Mold guide pillar structure

Abstract

The invention relates to a mold guide pillar structure. The structure comprises a fixed mold and a movable mold matched with the fixed mold, receding grooves are formed in the fixed mold, guide blocks are installed in the receding grooves, square guide pillars are fixedly arranged on the movable mold, the square guide pillars are arranged in the receding grooves in a sliding manner, wear-resisting plates corresponding to the guide blocks in position are arranged at the two sides of the square guide pillars, the wear-resisting plates protrude out of the side walls of the square guide pillars, the guide blocks protrude out of the side walls of the receding grooves, and the wear-resisting plates are in contact fit with the guide blocks and guide the square guide pillars to slide. The structural form that the wear-resisting plates are installed on the side faces is adopted, only the wear-resisting plates need to be repaired, the repairing difficulty of a bench worker is reduced, and the problems that in the prior art, a whole guide pillar needs to be repaired, and repairing is difficult and time-consuming are solved.

Description

technical field [0001] The invention belongs to the field of moulds, and can specifically relate to a mold guide post structure. Background technique [0002] With the rapid development of the car lamp industry, its shape structure tends to develop in the direction of complexity, and the car lamp products with large shapes and sizes are more and more in line with people's aesthetics. What follows is that the requirements for the matching mold products are getting higher and higher, and the overall size is getting bigger and bigger. [0003] At the same time, in order to ensure the stability and reliability of the mold structure, the mold designer usually symmetrically designs positioning structures such as the guide post body on the periphery of the mold with a deep cavity drop and a large size drop. With its stable structure, the guide column body mechanism can also withstand a certain lateral force of the mold to ensure the relative position of the mold, the moving mold c...

AI Technical Summary

Problems solved by technology

However, the traditional guide column body mechanism adopts an integral design, which is difficult to disassemble and assemble, which consumes a lot of repair time for the fitter

At the same time, the position deviation caused by various factors such as its fixing method, material selection, and fit clearance will also cause brittle fracture of the guide post body without obvious deformation.
