Description

Technical Field

[0001] This utility model belongs to the field of mold technology, and in particular relates to a strong release structure for an ultra-thin snap-fit ​​mold. Background Technology

[0002] Molds are tools used to make shaped items. In industrial production, they are various molds and tools used to obtain the desired products by methods such as injection molding, blow molding, extrusion, die casting or forging, smelting, and stamping. They are widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, and pressure casting. Among them, injection molds are mainly used for the production of injection molded products.

[0003] Currently, injection molds used in industry are usually equipped with corresponding ejection mechanisms. The ejection mechanism ejects the molded product to remove it from the mold. The ejection effect of the ejection mechanism plays a crucial role in the production efficiency and pass rate of injection molded products.

[0004] Most existing injection mold ejection mechanisms are vertical ejection mechanisms, which are suitable for ejecting injection molded products with good flatness. However, when the injection molded product is an irregularly shaped product such as an automotive headlight interior trim ring, the vertical ejection mechanism cannot eject the injection molded product smoothly and cannot meet the ejection requirements of the injection molded product, resulting in poor ejection effect of the injection mold ejection mechanism for irregularly shaped products.

[0005] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a strong ejection structure that can tilt and eject. Utility Model Content

[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide an ultra-thin snap-fit ​​mold strong release structure.

[0007] To solve the above problems, the present invention adopts the following technical solution: A strong release structure for an ultra-thin snap-fit ​​mold, characterized in that it includes a moving mold and a top plate. The mold core on the moving mold is designed and formed with ejector pin holes. If there are several mold cores, each mold core has at least one or more ejector pin holes. The ejector pin holes are through slots, allowing the top plate to be inserted and make directional reciprocating motion under the drive of the ejection system. The ejector pin holes are designed with an angle, which is formed inclined on the moving mold, and the top plate fitted with it also has the same angle. The top plate has an integrally formed tapered structure on one side connected to the ejection system, while the other side is designed with a snap-fit.

[0008] Preferably, the surface where the top roller hole contacts the snap fastener on the top plate is a curved surface design.

[0009] Preferably, the top plate is integrally formed from a separate metal plate. Beneficial effects of this utility model Compared with the prior art, the advantages of this utility model are as follows: This utility model, through the setting of the corresponding structure, enables the injection mold to have the function of tilting ejection, which can be used to eject irregularly shaped products such as automotive headlight interior rings, thereby improving the ejection effect and yield of irregularly shaped injection molded products. One of the detailed designs can realize the function of sliding first and then forcefully ejecting, and this design is a buckle design on the top plate that can work with the mold core.

[0014] To better understand the purpose, structure, and function of this utility model, a more detailed description of this utility model is provided below with reference to the accompanying drawings.

[0015] like Figures 1 to 5 As shown, the main improved structural parts of this utility model are the moving mold (1) and the top plate (2). The specific modified technical structure is as follows: The moving mold (1) has a mold core with an ejector pin hole (10) designed and formed. If there are several mold cores, each mold core has at least one or more ejector pin holes (10). The ejector pin hole (10) is a through slot, which allows the top plate (2) to be inserted and reciprocated under the drive of the ejection system. The ejector pin hole (10) is designed with an inclination and is formed on the moving mold (1). The top plate (2) fitted with it also has the same inclination. The top plate (2) has an integrally formed end cap structure (20) on one side connected to the ejection system, and a buckle (21) is designed on the other side.

[0016] It can be further explained that the closing structure (20) of the top plate (2) is an auxiliary structure for connecting and fixing the top plate (2) to the ejection system, so as to achieve a direct and stable assembly connection. The buckle (21) plays a role in limiting and positioning when the top plate (2) falls and resets, ensuring that its travel is within the distance.

[0017] The inclined ejector pin hole (10) plays a role in positioning, limiting and guiding the movement of the top plate (2), thereby ensuring the smoothness of its operation and improving the yield of ejected injection molded parts.

[0018] Regarding the top plate (2), it can also be explained that it is made of an independent metal plate in one piece, which not only has strength but also saves volume and assembly space. The ejector pin hole (10) that works in conjunction with the buckle (21) of the top plate (2) has a curved surface (11) that contacts the buckle (21). This structural design can increase its contact area with the moving mold, further enhance the limiting and positioning function, and also ensure its required sliding and then forceful release function.

[0019] By optimizing the structure of the above technologies, the previous vertical ejection structure design can be changed to an inclined ejection structure design, which can match the production of irregularly shaped products, ensure smooth ejection of such injection molded products, guarantee the ejection mechanism of the injection mold for ejecting irregularly shaped products, and improve the yield rate.

[0020] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
