[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention is a method suitable for taking out molded products, especially molded products of special shapes, in a vertical direction from a bottom mold for molding. This invention relates to a mold release device for molded products.

(Conventional technology) Conventionally, for example, press forming of glass products was performed using the fourth
The process is as shown in the figure. This device usually has 8
The bottom mold B of the stand was installed and rotated in the counterclockwise direction shown by the arrow, so that the molded product K was taken out from the B6 position in the direction shown by the arrow.

That is, the glass gob G is accommodated in B1, and the glass gob G is accommodated in B2.
Pressing is performed in And B3, B
4, the molded product K that has passed through B5 is taken out at B6 in the direction indicated by the arrow.

A conventional take-out device used in such a process is shown in FIG. In FIG. 5, the impact when the vertically movable vacuum head 1 descends and comes into contact with the molded product K is alleviated by the elasticity of the built-in spring 2. Then, as the vacuum head 1 moves upward, the air a shown by the arrow is sucked from the bottom mold B6, so that the molded product K is attracted, detached from the bottom mold B6, and lifted in the vertical direction. There is.

(Problem to be solved by the invention) However, if the bottom mold B is inclined with respect to the horizontal plane, or if the molded product is
Specially shaped molded product with a convex part D on the outer wall of K'
In the case of K', there was a problem in that even if the molded product K' was sucked up vertically by the vacuum head 1 in the bottom mold B6, the convex part D was locked to the bottom mold B6, and the molded product K' could not be removed from the bottom mold B6. .

Therefore, the present invention was devised in order to take out the molded product with the above-mentioned special shape, and after tilting the molded product toward the convex part and retracting it, the molded product is moved two-dimensionally in the vertical direction. It is an object of the present invention to provide a mold release and take-out device for molded products that can be easily taken out by.

[Structure of the idea]

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a take-out device for taking out a molded product molded in a mold from the mold, which includes first and second shafts each having a buffer member. a liftable guide plate that supports the upper ends of the two shafts and that is inserted through the first shaft and rotatably pivots the upper end of the second shaft; a liner rotatably connected at both ends to the lower end of the second shaft and having means for adsorbing the molded product in the center thereof, and as the guide plate moves up and down, the first shaft Rotating the liner using the side end as a fulcrum,
The molded product is tilted at a predetermined angle and taken out from the mold.

(Function) In the device configured in this way, since the first shaft passes through the guide plate,
The distance between the liner connected to the lower end of the first shaft and the guide plate can be varied. That is, when the guide plate is raised, this distance increases, and when it is lowered, it contracts. On the other hand, the second
Since the upper end of the second shaft is pivotally connected to the guide plate on the shaft side, the distance does not change as much as on the first shaft side. Therefore, when these movements are taken together, when the guide plate is lowered, the liner is in a substantially horizontal state, and when it is raised, it is in an inclined state so as to face the second shaft side. Therefore, when a molded product having a protrusion D on the side as shown in FIG. It is tilted to avoid getting stuck in B and can be taken out upwards.

(Example) The present invention will be described below based on an example shown in FIGS. 1 and 2. Figure 1 is similar to Figure 3.
This figure shows a two-dimensional operation take-out device 10 (hereinafter referred to as take-out device) used to take out products at position B6. A guide plate 12 is disposed perpendicularly to the lower end of a pipe 11 that is supported to be movable up and down and horizontally by a drive mechanism (not shown). This guide plate 12 has a shaft 13 fitted with a spring 15 that elastically relieves the force applied to the molded product.
is inserted through the shaft 13, and a stopper 14 is screwed onto the lower end of the shaft 13 to abut the tip of the take-out device 10 against the bottom mold B to determine the operating reference position of the take-out device 10 when the take-out device 10 is lowered to take out the molded product.

Further, the guide plate 12 has a link shaft 16 whose lower end is rotatably connected to one end side of the liner 18 and which has a built-in spring 17 that moves in response to the rise and fall of the guide plate 12. let The other end of the liner 18 is screwed onto the shaft 14, and the liner 18 is shaped so that when the lower surface abuts against the molded product K', there is no gap between it and the edge of the molded product K'. . For example, in this embodiment, the lower part 18b of the liner 18 is inclined at about 13 degrees to the left in FIG. 1 in accordance with the inclination of the upper opening of the molded article K'. Furthermore, a through hole 18a is provided approximately in the center of the liner 18, and is configured to be connected to an air compressor (not shown) so as to adsorb the molded product K' under reduced pressure.

Next, the operation of the present invention based on the above configuration will be explained with reference to FIGS. 2A to 2F. In the following description, the rotatable connection portion between the shaft 13 and the liner 18 will be referred to as the first fulcrum P1 and the link shaft 1.
6 and the liner 18 will be described as a second fulcrum P2.

First, in FIG. 2A, the take-out device 10
When the bottom mold B descends in the direction of the arrow, the stopper 14 comes into contact with a notch Bp cut out at the end of the bottom mold B and stops. Next, in FIG. 2B, the guide plate 12 continues to descend due to the remaining force from the top, and the liner 1
8 comes into contact with the molded product K'. At this time, the spring 15 fitted into the shaft 13 contracts to reduce the impact upon contact. The guide plate 12 further descends until it reaches FIG.
7, the liner 18 is completely molded.
Close to K′. Here, the molded product K' having the convex portion D on the left side is set so that its opening side is inclined to the left by about 13 degrees with respect to the horizontal, and the liner 1
Since the lower contact surface 18b of No. 8 is also set to be tilted to the left by about 13 degrees with respect to the horizontal, the two can be brought into close contact with each other without any gap. Next, the molded product K' is brought into close contact with the liner 18 of the take-out device 10 by suction from the air compressor.

When the guide plate 12 starts to rise as shown in FIG. 2D, the spring 17 built into the link shaft 16 expands and returns to its original position.
When the guide plate 12 further rises, the second fulcrum P2 side of the liner 18 is pulled up in conjunction with the link shaft 16 and rotated about the first fulcrum P1, so that the molded product K' moves the convex portion D downward. It is held tilted.

Therefore, the convex portion D is separated from the concave portion of the bottom mold B (see FIG. 2E).

Next, in FIG. 2F, the spring 15 on the shaft 13 side returns to its original position, so that
The take-out device 10 can take out the molded article K' in the vertical direction while keeping it in an adsorbed state.

In this embodiment, since the stopper 14 is screwed, the height of the liner 18 relative to the bottom mold B can be easily adjusted, and by replacing the lower contact surface 18b of the liner 18 or the liner 18. Can handle a wide variety of products.

[Effect of idea]

As explained above, according to the present invention, a link shaft for tilting and taking out a molded product, a liner pivotally attached to the link shaft, and a buffer member for relieving the force applied to the molded product are assembled. By combining these two dimensions, it becomes possible to perform a two-dimensional operation in which the molded product is tilted and then taken out in the vertical direction, instead of a one-dimensional operation in which the molded product is taken out only in the vertical direction. Molded products with special shapes can also be easily removed.

In addition, since it is possible to operate automatically, there is no need for manual labor, and since the pressure applied to the molded product is alleviated by the cushioning member, there is no risk of damage to the molded product. It has the effect of being able to do it.
