A guiding, anti-side, and limiting structure was designed, in which the guide plate fixing seat and the limiting cover plate are integrated. The upper mold plate is guided by the friction between the guide slider and the guide plate, and a nitrogen spring is used to provide a limit when the mold is opened, ensuring the stability and limiting function of the upper mold base.
It achieves stability during mold operation and limits the upper mold pressure plate, preventing lateral movement and improving the stability and safety of mold use.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold technology, and in particular to a structure for guiding, preventing side movement, and limiting the pressure plate of a mold. Background Technology
[0002] In recent years, with the increasingly fierce competition in the automotive market, major automakers have turned their attention to the body panels and related stamped parts (hereinafter collectively referred to as parts) of the car itself in the development and research of new models. The requirements for them are getting higher and higher, and the parts are becoming more complex, stronger, more diverse, and varied in shape. When the parts are subjected to large lateral forces during forming, the mold tends to be biased to one side and there is no space to install a separate anti-side component.
[0003] The existing mold pressure plate causes the mold to be biased to one side when faced with a large lateral force during the forming of the part, and there is no space to install a separate anti-side load component.
[0004] Therefore, we propose a structure for guiding, preventing side movement, and limiting the pressure plate of a mold. Utility Model Content
[0005] In view of the shortcomings of the existing production technology, the applicant provides a structure for guiding, preventing side movement, and limiting the pressure plate of a mold, so that the guide plate fixing seat and the limiting cover are integrated. While playing a limiting role, it can also restrict the upper mold pressure plate, which can ensure the stability of the upper mold base when it is working, and can also play a limiting role when the upper mold pressure plate is in place.
[0006] The technical solution adopted in this utility model is as follows:
[0007] A structure for guiding, preventing lateral movement, and limiting the pressure plate of a mold, comprising:
[0008] Upper mold base;
[0009] The upper die pressing plate is located below the upper die base, and side grooves are provided on both sides of the upper die pressing plate;
[0010] Two guide plate fixing seats are fixed on both sides of the bottom of the upper mold base, and the two guide plate fixing seats are respectively located in two side grooves;
[0011] Among them, the upper mold pressing plate is provided with a guide block on the outside of the side groove, and each guide plate fixing seat is provided with a guide plate corresponding to the guide block, and the guide plate is in contact with the guide block; each guide plate fixing seat is provided with a limit cover plate at the bottom;
[0012] A spring is installed at the bottom of the upper mold base, and the other end of the spring is connected to the upper mold pressure plate.
[0013] Its further features are:
[0014] Four springs are provided, and each spring is located on one side of the bottom of the upper mold base.
[0015] The top of the upper die pressing plate is provided with a first recess on the outer side of each side groove.
[0016] The width of the guide block is greater than the width of the first recess, the guide block extends into the side groove, and one side of the guide block extends beyond the corresponding side edge of the side groove.
[0017] The spring is a nitrogen spring.
[0018] Each side groove has three sides, and three guide plates are provided, with one guide plate corresponding to one guide slider.
[0019] In the initial state, the spring is compressed and can continue to be compressed.
[0020] The guide plate fixing seat is provided with a second recess, and the guide plate is disposed in the second recess. The thickness of the guide plate is greater than the depth of the second recess.
[0021] The beneficial effects of this utility model are as follows:
[0022] This utility model features a compact and reasonable structure, and is easy to operate. During a single operation, when the upper die pressure plate moves upward, the guide slider on the upper die pressure plate rubs against the guide plate on the guide plate fixing seat, providing guidance and preventing lateral forces. When the mold opens, the spring force pushes the upper die pressure plate downward, and then the limiting cover plate limits the upper die pressure plate. This ensures the stability of the upper die base during operation and also provides a limiting function when the upper die pressure plate is in place. The guide plate fixing seat and the limiting cover plate are integrated, providing both limiting and restricting functions for the upper die pressure plate. Attached Figure Description
