Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a mold setting device that transports molds such as press molds from a predetermined transport position to a target setting position. be.

(Prior art) Recently, for example, in order to transport a replacement mold to a press machine, it has become common to use a trolley for a predetermined mold set (for example, (See Publication No. 57329). If you use the trolley for Mold Seno 1 like this,
For example, compared to the lifting transfer method using a crane or forklift as shown in JP-A No. 62-220228, both the transfer speed and mold exchange efficiency are higher, which ultimately improves the operating efficiency of the press itself. It has the advantage of being able to encourage people to move forward.

(Problem to be Solved by the Invention) By the way, the above-mentioned mold set cart currently in use is located near a press machine and is carried from a predetermined mold receiving section (mold receiving station) to the press machine's bolster. It can be moved arbitrarily on the rails placed on the floor until it reaches a partially visible position, and the molds received at the mold receiving section are first set accurately on the trolley. Then, it is transferred to a position facing a part of the bolster of the press machine.

When it comes to a position facing a part of the bolster, it is horizontally placed on the bolster of the press using an extrusion transfer device such as lazy tongs that has a predetermined link mechanism and is configured to be extendable and retractable. A system is adopted in which it is transferred and finally locked and fixed (for details, refer to the above-mentioned Utility Model 5).
8-57329).

However, even in this system, the loading of the mold onto the trolley in the mold receiving section, and the transfer and loading of the mold from the trolley to the bolster each require complicated positioning and locking work each time. If each of these operations is not performed accurately, there is a problem in that accurate transfer onto the bolster and accurate press operation cannot be achieved.

In addition, since molds are generally transported from the mold storage section to the mold receiving section by a crane (often an overhead crane), the molds must be set (hanged and lowered) onto a trolley at the mold receiving section. , the accompanying positioning and locking) are complicated operations that require a certain degree of skill.

In addition, there are similar problems with the loading/unloading and positioning of molds onto the bolster, and the final centration of the upper and lower molds.In particular, strict precision is required when molds are set on one side of the bolster. At the same time, the press machine was not operating during the setting work, resulting in poor operating efficiency.

(Means for Solving the Problems) The present invention has been made for the purpose of solving the problems of the prior art as described above. In a mold setting device configured to set a mold by transporting a gold pear using a transporting trolley, the upper surface of the aforementioned trolley and the upper surface of the target mold set section A die set plate is provided in each section that can be commonly locked or fixed, and a mold can be installed on the upper surface of the die set plate, and the die set is placed on the trolley surface of the mold receiving section. The die setting plate and the mold are installed on a plate, and the die set plate and the mold are transported from the mold receiving part to the intended mold setting part via a trolley, and then set in the mold setting part. It is characterized by the fact that

A configuration is adopted in which a reference pin for positioning is provided on the upper surface of the die set plate, for example, to serve as a marker when installing a mold.

(Function) In the configuration of the mold setting device of the present invention, as described above, the mold is transferred and set using a mold transport trolley from a predetermined mold receiving part to a part of the bolster of the press machine. In the mold setting device, a die set 71-play 1- is provided with positioning and locking means such as a predetermined positioning reference pin or lower mold locking means on the upper surface of the cart. The die set plate is placed on the die set plate, and the mold is set on the truck surface or the entire bolster surface through the die set plate. Initial setting can be performed relatively easily by simply setting the mold as a reference, and after the initial setting, the gusset plate itself serves as a reference and can be easily set to the final setting position.

(Effects of the Invention) Therefore, according to the mold setting device of the present invention, the mold exchange efficiency is greatly improved, and the operating efficiency of the press machine is increased.

(Example) FIGS. 1 to 11 show a mold setting device for a press machine according to an example of the present invention.

First, FIG. 1l shows the overall layout 1 of a mold transfer/exchange system in a predetermined press factory.

In FIG. 11, reference numeral 1 denotes a mold station, and the mold station 1 stores a large number of various molds used in a press machine 9, which will be described later.

On the other hand, reference numeral 3 designates a mold receiving section, in which a trolley 4 for transporting molds as shown in FIGS. 9 and 10, which will be described later, is placed on standby. This trolley 4 is moved by a motor or the like on two rails 5 and 5 extending from the mold receiving section 3 to the mold setting station 6, which is the population section of the target press 9. It is possible and installed.

On the second side of the carriage 4 of the mold receiving section 3, a die set 1, play 1, (see FIG. 1) 20 for mold setting is placed, as will be described in detail later.

Then, on the second surface of the pedestal 4A, the above-mentioned polster 1 of Guiset 1, Play 1, and 20 is placed as described above.
Multiple ports 30, 30 to facilitate transfer to the 0 side
It is installed using a predetermined groove 31.31.

On the other hand, the reference numeral 32 has short links 32a, 32a and long links 32b, 32b that are rotatably attached to each other as shown in the figure, so that the entire structure linearly expands and contracts on the axis (A)-(B). The base end 33 of the lazy tongs is pivoted and fixed to one end side (the front side in the mold transfer direction) of the casing to which the pedestal 4A is fixed.

On the other hand, the tip side thereof engages with an engagement piece 23 provided on an example of a tie set plate 2o, which will be described later, placed on the pedestal 4A to push out the die set plate 20 in the direction of the bolster IO. Or, conversely, a hook-shaped latch 35 is attached for pulling.

On the other hand, a female threaded hole 37 is formed in the lower part of the intersecting shaft 36 of the long links 32b, 32b, which is the central intersection of the lazy tongues 32, and the female threaded hole 37 has both front and rear ends facing toward the pedestal 4A. A male screw rod 39, which is rotatably supported by fixed bearings 38a and 38b, is inserted therethrough in a screwed state.

Of course, in this case, the central axis of the male threaded rod 39 is as described above (

For example, as shown in FIG. 5, a groove 20a on the soil surface side is formed at the front end of the grip set plate 20, and a hook-shaped engaging piece 23 having a predetermined protruding height is formed in the groove 20a. A structure is adopted in which the parts 23a are engaged and fixed and integrated with bolts 23b, and the structure is sufficiently strong against pushing and pulling in the directions of arrows (a) and (b), as well as against forces in any direction. It has a structure. Note that the arrow (c) indicates the direction in which the latch 35 of the lazy tongues 32 is engaged.

Therefore, first, when the carriage 4 is in the mold receiving part 3 as described above, the die set plate 20 with the above structure is moved from side to side by engaging the guide grooves 21 and 22 with predetermined pins on the pedestal 4A side. Then, the front and rear positioning is performed, and the die set 1-plate 20 itself is held in a state of being pulled in the direction of the arrow (mouth) in FIG. Ru.

In this state, the mold S to be replaced or set is suspended from above. Then, in the suspended state,
The position of the mold S is set to X- on the die set plate 20.
The first and second reference pins P, P, are formed on the mold side by alignment with reference to the Y reference lines Lx, Ly. The mold S is set in a state where it is fitted into the first and second reference bottle fitting holes (not shown).

In other words, in this case, the mold S is placed on the trolley 4 as described above.
Since the tie set plate 2o is installed on the pedestal 4A of the tie set plate 20, it is easy to make a And it will be set correctly for Army Inclusion 4.

Next, the trolley 4 with the mold S set in this way is
