Embodiment Construction

[0045] The double-material injection molding machine of the present invention includes a mold clamping mechanism, a turntable mechanism, a plastic injection mechanism, a liquid silicone injection program mechanism, a plastic heating and feeding mechanism, a mixer composed of a dynamic screw connected to a static mixing tube, a hydraulic system and electronic control system. Among them, the mold clamping mechanism is a direct pressure mold clamping mechanism of horizontal mold clamping, which is used to complete the opening and closing of the mold. The mold clamping mechanism includes a movable template, a rear mold, a front mold and a fixed template. A set of molds with at least two symmetrical mold cavities can be installed on the end face of the rear template, and a set of molds corresponding to the mold cavities of the rear mold can be installed on the end surface of the front template. The corresponding mold cavities on the end faces together form the appearance shape of ...

Abstract

The invention provides a double-material injection moulding machine and a forming method thereof. The double-material injection moulding machine is mainly used for the product production of a mixing injection moulding process of a thermoplastic plastic and a thermosetting liquid silica gel. The double-material injection moulding machine comprises a mould closing mechanism, a rotating disc mechanism, a plastic injection mechanism, a liquid silica gel injection moulding mechanism, a plastic baking and feeding mechanism, a mixer, a hydraulic system and an electric control system, wherein the mixer is formed by connecting a dynamic screw rod and a static mixing tube. According to the double-material injection moulding machine, the rotating disc mechanism can rotate a rear mould plate at 180 degrees so as to exchange mould cavities inside a mould, so that the product is processed at a time, high accuracy of a synthetic product is achieved, the requirement of a customer on the product is easily met, and adverse effect generated due to secondary processing is prevented. The double-material injection moulding machine provided by the invention has the advantages of time conservation, convenience for operation and facilitation in production work.

Description

technical field [0001] The invention relates to a double-material injection molding machine and a molding method thereof, belonging to the technical field of injection molding. Background technique [0002] Injection molding is an important processing method in the field of plastic processing. It has the advantages of short production cycle, can form plastic products with complex shape and precise size at one time, has strong applicability to the raw materials used, high production efficiency, and can realize automatic production. The injection molding machine makes thermoplastics or thermosetting plastics undergo heating, shearing, compression mixing and conveying in the heating barrel, melts, plasticizes and homogenizes them. Then apply pressure to the plasticized material by means of the screw, forcing the high-temperature melt to rush into the cavity of the closed mold, and after cooling and solidification, plastic products with certain geometric shape and dimensional ac...
