Wind wheel mold structure with composite slide structure

Abstract

The invention relates to the technical field of injection molds, in particular to a wind wheel mold structure with a composite slide structure, which comprises a first mold, a second mold and a plurality of slide structures, the first die can move relative to the second die; the slide structure comprises a mold core assembly, a slide assembly, a linear power piece and a relative movement piece; the linear power part is arranged on the first mold or the second mold and connected with the slide assembly, a rim forming surface is arranged at the top end of the mold core assembly, and blade forming surfaces are arranged on the two sides of the mold core assembly; a forming cavity is defined by the mold core assembly, the first mold and the second mold; the relative movement part is connected with the mold core assembly and the slide assembly respectively; the mold core assembly is in linear sliding connection with the slide assembly, and the linear sliding direction between the mold core assembly and the slide assembly and the linear power direction of the linear power piece are located in the vertical plane and have acute angles. According to the wind wheel demolding device, step-by-step demolding of the wind wheel can be achieved, and the defect of mold drawing is avoided or reduced.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a wind wheel mold structure with a compound row structure. Background technique [0002] A traditional wind wheel mold includes a first mold, a second mold and a plurality of row structures, and the first mold, the second mold and the plurality of row structures are surrounded to form a forming cavity. When the fluid plastic injected into the forming cavity is hardened to form the wind wheel and needs to be demolded, the multiple row structures move in a direction away from the forming cavity as a whole to realize the demoulding. [0003] In summary, there are at least the following technical problems in the prior art, [0004] First, the contact area between the row position structure and the wind wheel formed by the hardened plastic is large, and the adhesion force is relatively large when the mold is removed once, which is easy to pull the wind wheel and cause it to n...

AI Technical Summary

Problems solved by technology

[0004] First, the contact area between the row position structure and the wind wheel formed by the hardening of plastic is relatively large, and the adhesion force is relatively large when the mold is demoulded, which is easy to damage the wind wheel and cause no light

[0005] Second, when the structure of the wind wheel is complex, the row position structure also needs to set a complex motion trajectory accordingly, resulting in a complex overall structure of the mold
