Description

[Detailed Description of the Invention] Technical Field The present invention relates to a chuck attachment for a take-out machine, and more specifically, to a chuck attachment that has a member for gripping a molded product of a take-out machine for a molding machine and is detachable. It is.

Prior Art The chuck attachment of an injection molding machine is required to be replaced.
Proposed by No. 61-50421. Although this known chuck attachment does not take into consideration the possibility of manually attaching and detaching the chuck attachment to the extractor, there are cases where it is necessary to attach and detach the chuck attachment manually. For example, if the attachment/detachment mechanism breaks down, or if the attachment needs to be replaced when the power required for automatic attachment/detachment is not being supplied due to circumstances in the molding machine, it is necessary to attach/detach it manually.

Purpose The purpose of the present invention is to provide a chuck attachment to a take-out machine that can be easily attached and detached either manually or automatically.

Structure The present invention has the above-mentioned purpose of providing a chuck plate with a mounting hole into which a support pin provided on the mounting plate of a take-out machine can be inserted and a member for gripping a molded product, and a guide mounted on the chuck plate. parts and
It has two opposing lock plates that are supported reciprocally by the guide member, and the lock plates are provided with an engaging portion that engages with the support pin, a manual operation portion, and an automatic operation portion, Furthermore, a spring is provided that presses the lock plate to an engagement position where the engagement portion engages the support pin, and the lock plate is engaged with the support pin against the spring pressure by pushing the manual operation portion or the automatic operation portion. This problem was solved by using a chuck attachment for the extractor that can be moved to the position where it is released.

With this invention, the lock plate is pressed and held by the spring force in a position where the engaging part engages with the support pin of the mounting plate inserted into the mounting hole of the chuck plate, and the chuck plate is fixed to the mounting plate. . By pushing the manual operation part by hand or moving the automatic operation part by an automatic device, the lock plate slides and is disengaged from the support pin, allowing the chuck plate to be detached from the mounting plate.

Embodiment In FIGS. 1 and 2, a chuck plate 3 of a chuck attachment 2 is removably fixed to a mounting plate 1 of a take-out machine.

A support pin 4 is embedded in the mounting plate 1, and a mounting hole 5 into which the support pin 4 is inserted is formed in the chuck plate 3. Although not shown, the chuck plate 3 is provided with a member for gripping the molded product.

The guide member 6 is attached to the chuck plate 3 with a screw 7.
A lock plate 8 is inserted and supported in a reciprocating manner into an opening formed by a guide groove 6a of the guide member 6 and the surface of the chuck plate 3 as shown in FIG. The number of guide members 6 is not limited to the illustrated example and can be selected as appropriate.

The lock plate 8 consists of two lock plates arranged opposite to each other in the moving direction, and a manual operation part 9 bent into a U-shape is provided at the adjacent end of each lock plate, and a manual operation part 9 bent into a U-shape is provided at the end opposite to each other. An automatic operation section 10 is provided on the side opposite to the manual operation section 9 and is bent into an L-shape toward the chuck plate 3.

A locking hole 11 is formed in the lock plate 8 as an engaging portion for the support pin 4. The form of the engaging part is not limited to a daruma hole, and can be arbitrarily selected as long as it has a structure that has a locking part that can prevent the support pin 4 from coming off and a detachable part that allows the pin 4 to be inserted and removed. In the case of the Daruma hole example, there is a large diameter hole 11a through which the support pin 4 can freely go in and out, and a small diameter hole 11b which engages in an annular groove formed in the support pin 4 and prevents relative movement of the support pin 4 in the axial direction. It is formed by

A spring 15 is provided between the manual operating parts 9 of both lock plates 8 to apply the pressing force of the lock plate 8, and the small diameter hole of the engaging part 11 engages with the annular groove of the support pin 4 at an engagement position. Give it the habit of moving and holding. One spring 15 can be placed directly between the manual operation parts 9, but in the example shown, the holder block 1 which also serves as a guide member for the lock plate 8 is used.
2 to the chuck plate 3 with screws 13, and two spring seats 14 for each lock plate formed in the holder block 12, for example the fourth
As shown in the figure, the bottom 12c of the hole 12b is formed into which the spring 15 can be inserted, and the respective lock plates 8
Two springs 15 are used so as to be tensioned between the manual operation section 9 and the manual operation section 9.

The part of the holder block 12 of the lock plate 8 that is inserted into the opening formed by the guide groove 12a and the surface of the chuck plate 3 as shown in FIG. It is formed in half of the guide groove 12a, and is formed so that the two lock plates can be moved relative to each other within the guide groove 12a while being juxtaposed side by side.

Normally, the two lock plates 8 are held in the engagement position by the force of the spring 15, where the engagement portions 11 are engaged with the support pins 4, respectively. When removing the chuck plate 3 from the mounting plate 1, by holding the two manual operation parts 9 from both sides with your hands and pressing them inward so that they approach each other, the lock plates 8 will move outward against the spring force. The lock plate 8 moves relative to the support pin 4, and the engagement portion 1
The support pin 4 of the mounting plate 1 can be inserted into the large diameter portion 11a serving as the attachment/detachment portion of the attachment plate 1. At this time, if the mounting plate 1 is moved upward in FIG. 1 and the chuck attachment 2 is fixedly held, the chuck attachment 2, that is, the chuck plate 3
can be easily removed from the mounting plate 1.

When you release your hand pushing the manual operation part 9, the lock plate 8 automatically moves to the engagement position by the force of the spring 15, and if the support pin 4 is inserted into the mounting hole 5, the lock plate 8 is moved to the engagement position by the force of the spring 15. A small diameter hole 11b serving as a locking portion of the pothole 11 is engaged. Support pin 4
is not inserted, the edge of the notch 16 of each lock plate 8 is inserted into the mating lock plate 8.
The lock plates 8 are stopped and held at appropriate positions.

The automatic operating portion 10 of each lock plate 8 is fitted into a notch 17 of the chuck plate 3, but the notch 17 may be omitted if necessary.

When the chuck plate 3 is to be automatically removed from the mounting plate 1, a lock plate is installed on an external device such as a change stand that securely holds a chuck attachment (not shown), as shown in part in FIG. An automatic attachment/detachment device is used which has an engaging claw 18 that engages with the automatic operation section 10 of No. 8 and is capable of reciprocating movement. The locking plate 8 is compressed by the spring 15 by moving the engaging claw 18 of the automatic attachment/detachment device forward and hooking it to the automatic operation section 10, and then moving the engagement claw 18 back and pulling the automatic operation section 10. The large-diameter hole 11a of the pothole 11 is engaged with the support pin 4 to the disengagement position. Remove the chuck plate 3 in the same manner as in the manual case.

Effects According to the present invention, the chuck attachment can be manually attached to and detached from the mounting plate of the take-out machine by using the manual operating section, and can also be automatically attached and detached using the automatic operating section.

With this invention, the chuck attachment can automatically remove the one that was manually attached to the extractor, and conversely, it can also manually remove the one that was automatically attached, making it possible to switch from automatic to manual at will. Available.
