Problems solved by technology

[0002] like figure 1 As shown, there are horizontal horizontal side holes on one side of the cavity of the product, which requires core-pulling and demoulding. There are many side holes on one side of the core, which requires side-pulling and demoulding. The product itself has many ribs, and injection molding is not easy. It is easy to cause uneven shrinkage during balance, resulting in severe uneven shrinkage of the product and large warping deformation; therefore, it is necessary to design a reasonable gating system, demoulding mechanism and overall structure of the mold

Abstract

The invention provides a front mold slide injection mold. The front mold slide injection mold comprises a mold plate structure assembly, an ejection assembly, a forming part assembly, a mold plate opening and closing control assembly, a casting system assembly, a mold plate guide assembly, a front mold first core pulling assembly, a front mold second core pulling assembly, a front mold third corepulling assembly and a front mold fourth core pulling assembly. According to the front mold slide injection mold, the technical problems that a product has multiple rib positions, a front mold side hole needs to be demolded, the number of back side surface holes is relatively large, then injection molding is prone to deformation and the molding is difficult are solved, the front mold slide injection mold has the beneficial effects that core pulling and demoulding of four side edges of the product and the inner hole of the front mold surface are achieved through the designed mold, through reasonable casting system design and reasonable layout design of a side core-pulling demoulding mechanism, the influence of buckling deformation on product during demoulding of the side core pulling mechanism is reduced, and the product rejection rate is reduced.

Description

technical field [0001] The invention relates to the field of injection mold mechanism design, in particular to a front mold line injection mold. Background technique [0002] Such as figure 1 As shown, there are horizontal lateral side holes on one side of the cavity of the product, which requires core-pulling and demoulding. There are more side holes on one side of the core, which requires side-pulling and demoulding. The product itself has many ribs, and injection molding is not easy It is easy to cause uneven shrinkage during balance, resulting in severe uneven shrinkage of the product and large warping deformation; therefore, a reasonable gating system, demoulding mechanism and overall mold structure must be designed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a front mold line injection mold, which is reasonable in design, compact in structure, stable in operation, safe and reliable, and convenient to ...
