Description

[Detailed description of the invention] [Field of industrial application] The present invention is capable of separating and combining split molds, especially relatively large split molds for molding automobile transmission cases, etc., when installed on a machine. This invention relates to a carriage for transporting molds that is equipped with a mechanism that allows molds to be transported easily in the same posture as the molds.

[Conventional technology]

This type of casting mold for molding a transmission case consists of a movable mold and a fixed mold, and the fixed mold is slid laterally to separate and combine the two, so-called mold release. For split molds, a crane was used to perform this separation and assembly work.

In other words, the combination of the movable mold and the fixed mold is the seventh
As shown in Figure A, the movable mold 1 is placed on sleepers 3 spread out on the floor, the fixed mold 2 is hooked to the crane hook 4 and hoisted horizontally, and the movable mold 1 is placed in this state. Guide post 1a protruding from the end surface of 1
Using this as a guide, the fixed mold 2 was laterally moved in the direction of the movable mold 1 to combine the two molds 1 and 2, and this separation was performed in the opposite manner to the above.

The combined state of both 1 and 2 was then placed on a trolley 5 and transported, as shown in FIG.

In addition, in Japanese Utility Model Application Publication No. 55-60269, a plurality of rollers that rotate in contact with the outer surface of the mold are provided on the side of the conveyor on which the divided molds are placed and transferred, and the rollers are placed opposite to the rollers to rotate the conveyor. On the other side, a plurality of pressure cylinders were provided which were movable periodically in the same direction as the conveyor and pressed in the direction of the mold dividing surface, and these cylinders were configured to operate alternately with adjacent cylinders so that they could be transferred while pressing the mold. A mold clamping device for a casting machine has been proposed.

[Problem that the invention attempts to solve]

However, with the crane described above, if the fixed mold 2 has an unbalanced weight, it is not only impossible to hang it horizontally, but also it is difficult to place the movable mold 1 in parallel due to the unevenness of the floor and sleepers. In addition, lifting heavy objects with a crane is dangerous work in itself, and since the work of combining and separating the molds and this transport work were performed separately, the work was carried out smoothly without waiting time. The disadvantage was that it was not possible to move on to transport work, resulting in waste at work breaks.

In addition, what is described in Utility Model Application Publication No. 55-60269 is
The molds are transported using a conveyor, and it is thought that this method cannot be applied to carts.

[Means for solving problems]

In view of the above, the present invention allows for the installation and removal of fixed molds without the use of a crane, and also allows the installation and removal of fixed molds to be carried out from this installation and removal work to the mold transportation work, and vice versa. It was devised to provide a device that could shorten the time required to move the movable mold, and its gist was a movable mold receiving plate for horizontally placing the movable mold, and a movable mold receiving plate for horizontally mounting the movable mold. The mold conveying trolley is characterized in that it is provided with a fixed mold receiving plate which is slidable in the direction of the mold receiving plate and on which a fixed mold is horizontally placed.

(Function) Then, the movable mold is placed horizontally on the upper surface of the movable mold receiving plate, and the fixed mold is placed horizontally on the upper surface of the fixed mold receiving plate, and in this state, the fixed mold receiving plate is placed horizontally on the upper surface of the movable mold receiving plate. The movable mold and the fixed mold are combined by sliding in the direction of the mold receiving plate, and in the combined state, the fixed mold receiving plate is moved in the opposite direction to the above, that is, in the opposite direction of the movable mold receiving plate. This separation can be carried out on the respective carts.

〔Example〕

Hereinafter, the present invention will be explained in detail with reference to embodiments shown in FIGS. 1 to 5. In addition, Figure 1 is a front view,
Fig. 2 is a side view, Fig. 3 is an enlarged partially cutaway front view showing the connection between the fixed mold receiving plate and the cylinder for moving the receiving plate, and Fig. 4 is an enlarged cross section showing the tip of the mold clamp cylinder. FIG. 5 is an exploded perspective view showing the seated state of the fixed mold.

In the figure, 0 is the main body of the cart, and wheels 11 are rotatably attached to the lower four corners of the main body, and a power supply is secured, and inside this, although not shown, there is a self-propelled drive device such as an electric motor. It also has a built-in hydraulic pressure generating device for operating a mold clamp cylinder 19 and a receiving plate moving cylinder 27, which will be described below, and is configured to be able to run on rails 12 laid in the floor.

A base plate 13 is horizontally attached to the upper surface of this truck body 10 via a leveling adjustment mechanism 14, and a movable mold mounting plate 15, a tie bar fixing plate 16, and a cylinder mounting plate 17 are respectively mounted on the upper surface of this base plate 13. A slide plate 18 is fixed vertically and horizontally and parallelly between the movable mold mounting plate 15 and the tie bar fixing plate 16.

A mold clamp cylinder 19 is attached to the inner side of the movable mold mounting plate 15, respectively.
As this moves forward, this shaft 19
The flanges 1b of the movable mold 1 are clamped and fixed by hook-shaped clamps 21 connected to the ends of the movable molds 1 via coupling rings 20, respectively. Further, a tie bar 24 is installed between the movable mold mounting plate 15 and the tie bar fixing plate 16, and serves as a guide for the movable mold receiving plate 22 and the fixed mold receiving plate 23.

The movable mold receiving plate 22 and the fixed mold receiving plate 23 are placed so as to slide on the upper surface of the slide plate 18 using this as a sliding surface, and a positioning stopper 25 is interposed between them 22 and 23. At the same time, a back-up block 26 is fixed to the rear surface of the fixed mold receiving plate 23 for pushing the rear surface of the fixed mold placed thereon.

This movable mold receiving plate 22 is for horizontally placing the movable mold 1 on its upper surface, and a positioning pin 22a is provided approximately in the center of the movable mold receiving plate 22.
Side guides 22b are protruded from both sides of the plate, and the fixed mold receiving plate 23 is for horizontally placing the fixed mold 2, and a positioning pin 23a is located approximately in the center of the plate. Side guides 23b are located on both sides of the fixed mold 2 and protrude from each side.

The fixed mold 2 is seated on the fixed mold receiving plate 23 as shown in FIG.
This is done by inserting the positioning pin 23a into the positioning hole 2a drilled in the center of the hole, and inserting the side guide 23b into the guide groove 2b formed at the bottom of both sides. The same applies to the seating of the movable mold 1 on the mold 22.

The rear end of the cylinder 27 for moving the receiving plate is fixed to the cylinder mounting plate 17, and the tip of this shaft 27a is connected to a joint rod 29 having a male thread through a coupling ring 28. It is screwed and fixed to the fixed mold receiving plate 23.

Then, as the shaft 27a moves forward with the operation of the receiving plate moving cylinder 27, the fixed mold receiving plate 23 slides on the slide plate 18 toward the movable mold receiving plate 22 using the tie bars 24 as guides. This reverse operation causes the movable mold receiving plate 22 to slide in the opposite direction, that is, in the opposite direction of the movable mold receiving plate 22. Note that the forward end of the fixed mold receiving plate 23 is connected to the stop 25.
The retracting end is regulated by a limit switch.

Therefore, when combining the movable mold 1 and the fixed mold 2, the movable mold 1 is placed on the movable mold receiving plate 22.
The fixed molds 2 are each placed on the fixed mold receiving plate 23, and the mold clamp cylinder 19 is moved forward to clamp the movable mold 1, and the receiving plate moving cylinder 27 is operated to remove the fixed molds. This is done by sliding the mold receiving plate 23 and, by extension, the fixed mold 2 in the direction of the movable mold receiving plate 22 and, ultimately, the movable mold 1, and when they are in a combined state, they are lifted up with a crane while being combined. The receiving plate moving cylinder 27 is activated in advance to move the movable mold receiving plate 22 forward, and the movable mold receiving plate 22 is placed thereon, and after the movable mold 1 is clamped by the mold clamp cylinder 19, the fixed mold receiving plate is moved. This is done by reversely operating the plate 23 and sliding it in the opposite direction.

What is shown in FIG. 6 shows another embodiment.
Devices similar to those described above are provided on the left and right sides of the movable mold mounting plate 15 on the trolley body 10'.

In this way, by providing them on the left and right, a pair of movable molds 1' and fixed molds 2' and a pair of movable molds 1'' and fixed molds 2'' are conveyed simultaneously, and the fixed molds 1
2' and 2'' can be attached and detached at the same time.

[Effect of idea]

As described above, the mold conveyance trolley according to the present invention has the following features:
A movable mold receiving plate for horizontally placing a movable mold, and a fixed mold receiving plate for horizontally placing a fixed mold so as to be slidable in the direction of the movable mold receiving plate. This configuration has the following effects.

The work of attaching and detaching the fixed mold can be carried out without using a crane, so not only is there no danger, but the crane can also be used more effectively.

It is possible to simplify the work of attaching and detaching the fixed mold and improve work efficiency.
