Blind flange injection molding process mold and usage method thereof

Abstract

The invention provides a blind flange injection molding process mold and a usage method thereof. For solving the problems that uneven deformation and high rejection rate of a product which is an application object of an existing mold are caused by difficult cooling of a molding part of the product when the product is small and round, demolding difficulty is caused by an inner trapezoidal thread feature of the product, and large final molding buckling deformation is easily caused by deviation between a gate position and the center of the product during the injection molding process, a mechanismdevice capable of realizing automatic molding of the product and guaranteeing molding quality of the product is designed. The blind flange injection molding process mold comprises a mold base assembly, a pin-point gate gating system assembly, a molding assembly, a thread core pulling mechanism assembly, a mold plate motion control assembly and an ejection assembly, realizes automatic non-deformation injection molding production of the product, and is reasonable in structure, reasonable in mechanism design, high in work reliability, and convenient to manufacture.

Description

technical field [0001] The invention relates to the field of injection mold mechanism design, in particular to a flange cover injection molding process mold and a use method thereof. Background technique [0002] Such as figure 1 As shown, there are the following problems in the injection molding of small flanged plastic products: 1) The product is relatively small and round, and it is difficult to cool the molded part, resulting in uneven deformation of the product and a high rate of product rejection; Trapezoidal thread feature, difficult demoulding; 3) The wall thickness of the product is thicker, and the tightness to the core is relatively large, so it is difficult to eject and demould; 4) During injection molding, the position of the gate is off-center and the injection molding is likely to cause the final molding of the product to warp The deformation is large. Therefore, it is necessary to design a mechanism device that can realize the automatic molding of the produ...
