Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Such as figure 2 As shown, an injection mold with three parting surface structures provided in this embodiment includes a fixed mold part, a movable mold part and an ejector mechanism. When the fixed mold part and the movable mold part are in the mold closing state, the fixed mold part The fixed mold core 21 of the mold part and the movable mold core 24 of the movable mold part jointly form a product cavity for injection molding a kind of belt through hole 101, and a rotary switch cover 103 with a concave-convex surface 102 is formed on the inner wall, as figure 1 shown;

[0020] The fixed mold fixing plate 1 of the fixed mold part is provided with a diagonal shift block 2 which forms an inclined angle with respect to the mold opening direction of the mould. The slider 4 on the frame 3, the slider 4 is provided with a core-pulling 5, the core-...

Abstract

The invention discloses an injection die, in particular to an injection die having a structure with three parts of parting surfaces. The injection die comprises a fixed die part, a moving die part and an ejector pin mechanism. When the fixed die part and the moving die part are in a die assembly state, a fixed die core of the fixed die part and a moving die core of the moving die part jointly form a product cavity used for the injection molding of a rotary switch cover with a through hole and with a concave and convex surface formed on the inner wall. The three separating processes of the three parts of parting surfaces of the injection die are simple. In the process of injection-molding one rotary switch cover with the through hole and with the concave and convex surface formed on the inner wall, the production failure rate is low, and the production efficiency is high.

Description

technical field [0001] The invention relates to an injection mold, in particular to an injection mold with three parting surface structures. Background technique [0002] Plastic injection molding is one of the most efficient production methods for plastic products, and it is also an important method of plastic molding. It is mainly suitable for the molding of thermoplastics. The parting surface is used on the mold to take out the plastic part or [0003] Separable contact surface for gating system aggregate. The design of the parting surface of the injection mold directly affects the quality of the plastic parts, the mold structure and the ease of operation are one of the keys to the success of the injection mold design. According to the number of parting surfaces, it can be divided into single parting surface injection mold and multi parting surface injection mold. [0004] In general, multi-parting surface injection molds are more complex in structure than single-part...
