A type of motor mounting seat mold

Abstract

The invention discloses a mold for a motor mounting seat, which belongs to the technical field of injection moulds. The main point of the technical scheme is that it includes a die and a punch, and the opposite end faces of the die and punch are provided with parting surfaces and located on the end faces. The molding surface in the center, the molding surface of the concave mold is recessed to form a molding cavity, and the molding surface of the punch is provided with a protrusion for cooperating with the molding cavity for injection molding, and the parting surface of the punch includes a first A parting surface and two second parting surfaces; the first parting surface is a concave arc surface, and the second parting surface is a plane, and are respectively located on both sides of the first parting surface in the length direction ; The parting surface of the die and the parting surface of the punch are adapted to each other. The invention has the advantages of good glue sealing effect, less flash and high smoothness of injection-molded products.

Description

technical field [0001] The present invention relates to an injection mold, more specifically, it relates to a motor mounting seat mold. Background technique [0002] figure 1 What is shown is a motor mounting seat, which consists of two halves of the motor mounting seat shell 1, and the openings of the two halves of the motor mounting seat shell 1 are relatively snapped together and fixed during assembly. This type of motor mounting seat is usually made of plastic raw materials through injection molding. Its injection mold such as figure 2 , image 3 As shown, the punch 2 and the die 3 are included, the punch 2 and the die 3 are arranged oppositely, and the opposite end faces of the punch 2 and the die 3 are respectively provided with a protruding part 21 and a molding cavity 31 for cooperating molding, Parting surfaces 4 are formed on the peripheral edges of the protruding portion 21 and the molding cavity 31 . The parting surface 4 of this kind of injection mold is m...

Problems solved by technology

[0003] However, the parting surfaces 4 of the above-mentioned molds are all flat, and it is difficult to ensure that the force is uniform everywhere when the molds are closed, so that the cooperation between the molds is not tight enough, the sealing effect is not good, and the processed products are prone to flashing , The finish is poor, which increases the processing cost of the subsequent process and affects the appearance quality of the injection molding workpiece
