The utility model relates to a combined plastic mold for compression molding, extrusion molding, injection molding, blow molding and low-foaming molding, which mainly includes a concave mold composite substrate, a concave mold component and a concave mold combined card board Consists of a concave mold with a variable cavity.
With the rapid development of the plastics industry and the continuous improvement of the strength of general plastics and engineering plastics, the application range of plastic products is also expanding, and the use of plastic products is also increasing.
Plastic molds are tools for producing plastic products. It consists of several groups of components. There is a molding cavity in this combination. During the injection molding process, the mold is clamped on the injection molding machine, the molten plastic is injected into the mold cavity, cooled in the cavity, and the upper and lower molds are separated. The product is ejected from the cavity through the ejection system, and then the mold is closed for the next time Injection molding. The entire injection molding process is cyclic.
The general plastic mold is composed of a movable mold and a fixed mold. The movable mold is installed on the movable template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. In injection molding, the movable mold and the fixed mold are closed to form a gating system and a cavity. When the mold is opened, the movable mold is separated from the fixed mold, and the plastic product is taken out.
The basic structure of the mold is the same, but the structure of the mold may be different due to the type and performance of the plastic, the shape and structure of the plastic, and the type of injection molding machine. The mold is mainly composed of a pouring system, a temperature control system, a molded part and a structural part. Casting systems and molded parts are parts that are in direct contact with plastics, and they change with changes in plastics and products. They are the most complex and variable parts in plastic molds, and they require finishing and precision.
The above is some basic content of mold processing, I hope to bring you some help. Some basic knowledge of mold processing
