In a so-called sleep rate mold using a nest (slide core) for forming an undercut surface on a molded product, the mold, that is, a fixed side plate of each mold, and a movable plate are movable until the nest escapes from the mold. The side plate or parting must be completely locked. For this reason, the present inventor has already devised Japanese Utility Model Publication No. 23774. This real fairness 1
In the conventional mold described in Japanese Patent No. 23774, one of a pair of opening / closing dies is provided with an insertion portion whose lower end is swelled, and the other is provided with a pair of claws for sandwiching the insertion portion, and a lock bar is inserted between the pair of claws. Then, the pair of claws were locked so as not to open. However, this requires a pair of claws, so that the device becomes large. Further, when the release bar is pulled by the release bar, an impact is generated when the release bar and the engagement protrusion of the lock bar are engaged, and the engagement protrusion is damaged. . Therefore, a lock device as shown in FIGS. 6, 7, 8, and 9 has been conventionally used. In this method, a projection 1a is pivotally mounted on one of the pair of opening and closing molds 1 and 2 by a shaft 2b, and a claw 2a engaging with the projection 1a is resiliently repelled by a spring 2c.
As shown in FIG. 6, a lock bar 7 is attached to the outside of the claw 2a.
a was locked so that it did not come off.

If the force is weak, there is a disadvantage that the lock is hard to be released. Further, the projection 1a is easily disengaged from the claw 2a, so that the engagement surface is displaced from the shaft 2b of the claw 2a. There is a disadvantage that the molded product or the nest is damaged, or the engagement surfaces are engaged with each other, so that the lock is hardly released.

外れることがないものである。Next, the operation of this device will be described. In the mold open state shown in FIG. 4, the cam 5a is engaged with the front portion of the slope 2g, and the claw 2a is disengaged from the projection 1a. When the mold is clamped from this state, the movable mold 1 operates forward, that is, to the right in FIG. As a result, the driven mold 2 is pushed forward, the slope 2g of the claw 2a is disengaged from the cam 5a, and the claw 2a is engaged with the projection 1a by the spring 2f, and is locked in the mold-clamped state shown in FIGS. State. The molding is performed in this state. Thus, the engagement surface between the projection 1a and the claw 2a is 3/1.
Since the precision is set to 00 or less, there is no backlash in the lock. Therefore, the protrusion 1a is hard to be painful, and the molded product, the nesting member is not damaged, or the lock does not become difficult to be disengaged due to the engagement of the engaging surfaces. The center of the shaft 2b of the claw 2a is the protrusion 1
The projection 2 is located on the vertical line at the center of the engagement surface between the projection 2a and the projection 2a.

出される。Next, when returning from the mold-clamped state shown in FIGS. 2 and 3 to the mold-opened state shown in FIG. 4, first, the opening and closing molds 1 and 2 are operated backward, and the space between the mold 2 and the runner stripper 4 is opened. , The runner separates from the molded product, and at the same time, the nest 2x comes off to the side. The runner stripper 4 also operates slightly behind the fixed-side mounting plate 3, and the runner lock pin comes off from the runner attached to the rear surface of the runner stripper 4, and the runner drops rearward. Thus, the slope 2g of the claw 2a is
When engaged with a, the claw 2a rotates upward against the elasticity of the spring 2f, the claw 2a comes off the projection 1a, and the lock is released. Next, the space between the molds 1 and 2 is opened, and the molded product is taken out.

いものである。As described above, according to the present invention, since the structure of the claw 2a is simple, the claw 2a can be provided in a small size and at a low cost, and the claw 2a is repelled by the spring 2f in the direction of engaging with the projection 1a. The lock is released, and the cam 5a is engaged with the slope 2g of the claw 2a to release the lock, so that the lock is released without any impact and is not damaged. It is. Further, in the present invention, since the engagement surface between the projection 1a and the claw 2a has a surface accuracy of 3/100 or less, there is no backlash in the lock. Therefore, the projection 1a is hardly painful and damages the molded product and the nest. There is no possibility that the lock will not come off easily due to the engagement or engagement of the engagement surfaces. Also, since the center of the shaft 2b of the claw 2a is on the vertical line of the center of the engagement surface between the protrusion 1a and the claw 2a, the claw 2a does not come off from the protrusion 1a even when a strong force acts. It is.
