Description

Technical Field

[0001] This utility model relates to punching dies, and more particularly to a plastic punching die. Background Technology

[0002] Existing punching dies are designed for horizontal punching of thin paper. It is proposed to expand their production applications to include punching of plastic film. Plastic film has low surface tension and requires high punching pressure. During horizontal punching, the moving die is prone to vertical displacement relative to the fixed die. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present utility model aims to provide a plastic punching die, wherein the guide post guides the longitudinal movement of the moving die, and the lifting adjustment mounting plate adjusts the guide post to keep the guide post horizontal.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the plastic punching die includes a fixed die and a moving die. The moving die is connected to a pressure plate through an elastic element. The pressure plate is located between the fixed die and the moving die. The die also includes mounting plates on both sides. The mounting plates are adjustable in height. The mounting plates are connected to guide posts. The moving die is longitudinally movable and is sleeved on the guide posts.

[0005] In this scheme, the lifting adjustment of one or both sides of the mounting plate corrects the levelness of one or both sides of the guide column.

[0006] Preferably, the guide post is connected to the fixed mold, and the guide post is fixedly installed.

[0007] In this design, the guide post is connected to the fixed mold, allowing the mounting plate to be adjusted based on the fixed mold, ensuring vertical alignment between the fixed mold and the moving mold.

[0008] Preferably, the moving mold is connected to a guide sleeve, and the guide sleeve is in sliding engagement with the guide post.

[0009] In this design, the guide sleeve reduces the coefficient of friction.

[0010] Preferably, the moving die is provided with a punching block, the pressure plate is provided with a through hole for the punching block to pass through, the fixed die is provided with a punching hole corresponding to the punching block, and the length of the punching block is greater than the gap between the moving die and the pressure plate.

[0011] In this scheme, the punching block is always inserted into the through hole during the longitudinal punching process, so that the pressure plate and the moving die are aligned vertically.

[0012] Preferably, the side of the fixed mold facing away from the pressure plate is defined as the back side. The back side of the fixed mold is provided with a reinforcing plate, which encloses to form multiple independent waste collection chambers. The waste collection chambers are connected to the punching holes, and the fixed mold is fixedly installed.

[0013] In this design, the waste collection bin facilitates the cleaning of waste materials, and the reinforcing plate increases the thickness of the fixed mold, enabling the fixed mold to withstand large punching pressures.

[0014] Preferably, the mounting plate is provided with a top block at the bottom end, the mounting plate has an inclined bottom surface at the bottom end, and the top block has a support surface that cooperates with the bottom surface.

[0015] In this scheme, the top block is moved to lift or lower the mounting plate, thereby achieving lifting and adjustment.

[0016] Preferably, the mounting plate is provided with a pressure block at its top, the mounting plate has an inclined top surface at its top, and the pressure block has a downward pressure surface that cooperates with the top surface.

[0017] In this design, the pressure block and the top block clamp the mounting plate, keeping the mounting plate in a vertical position.

[0018] Preferably, the bottom surface and the top surface are inclined in the lateral direction, and the top block and the pressure block are adjusted to move laterally.

[0019] In this design, the horizontal component of the force exerted by the top block and the pressure block on the mounting plate is transverse, which will not increase the longitudinal force on the fixed mold.

[0020] Preferably, the area between the two mounting plates is defined as the inner side, and the bottom surface and the top surface are in a figure-eight shape, with the figure-eight opening facing inward.

[0021] In this design, the horizontal component of the force exerted by the top block and the pressure block on the mounting plate is from the outside to the inside, and the horizontal component of the force on each part of the mounting plate is in the same direction, keeping the mounting plate vertical.

[0022] The beneficial effects of this utility model are as follows: The lifting adjustment of one or both sides of the mounting plate corrects the levelness of one or both sides of the guide posts; the pressure block and top block clamp the mounting plate, keeping it vertical; the horizontal component of the force exerted by the top block and pressure block on the mounting plate is from the outside to the inside, and the direction of the horizontal component force on each part of the mounting plate is uniform, thus keeping the mounting plate vertical. Therefore, this utility model has substantial features and progress compared with the prior art. Attached Figure Description
