Description

Technical Field

[0001] The utility model relates to the technical field of component molds, and specifically relates to a precise positioning pin component mold. Background Technique

[0002] At present, various molds and tools used in the industrial production of molds for injection molding, blow molding, extrusion, die casting, forging, smelting, stamping, etc. to obtain the required products. In short, a mold is a tool used to make formed articles. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the outer shape of the article by changing the physical state of the formed material.

[0003] In the prior art, the authorized publication number is: CN 217327997 U, and the name is a precise positioning pin component mold. The utility model discloses a precise positioning pin component mold, including a male pin. A female pin is clamped at the top of the male pin. A lower template is sleeved on the outer surface of the male pin. An upper template is arranged on the top of the lower template. Screws are installed inside the upper template in a threaded manner, and the bottom of the screw is on the same horizontal plane as the bottom of the upper template. The utility model uses this component to be installed around the mold cavity and used for mold closing positioning. The matching position uses a bilateral 0.65-degree fit for better positioning, which can improve the mold closing positioning accuracy. There is no need to worry about jamming when the male pin and the female pin are closed. The matching position uses a clearance fit for better mold opening and closing. The positioning sleeve is pressed and positioned by side screws to prevent the positioning sleeve from loosening. At the same time, it solves the problem that gaps are easily generated at the matching part after mold closing, reduces the positioning accuracy after mold closing, and it is impossible to open and close the mold better during later use, which is likely to cause the mold to jam.

[0004] Although the above description solves the problem that the mold is likely to jam during use, during use, since the male pin is installed in the lower template, the male pin can only fit with the mutually matching female pin to perform operations, and it is impossible to change the space in the cavity of the lower template according to the actual situation of the component to be processed. This means that the mold can only process specific types of components. It is impossible to change the space in the cavity of the lower template according to the actual situation of the component to be processed. Therefore, this design is not suitable for a production environment that requires frequent replacement or adjustment of the mold to process different components. Content of the Utility Model
