Description

An injection mold for lawn plastic bricks with good cooling effect

technical field

The utility model relates to the technical field of injection moulds, in particular to an injection mould of lawn plastic bricks with good cooling effect.

Background technique

Injection mold processing is to first add plastic into the mold, and then the mold is continuously rotated along two vertical axes and heated. Under the action of gravity and thermal energy, the plastic in the mold is gradually and uniformly coated and melted to adhere to the entire cavity of the mold cavity. On the surface, it is formed into the desired shape, and it is prepared by cooling and setting. A combined plastic mould for compression moulding, extrusion moulding, injection moulding, blow moulding and low foaming moulding mainly comprises a die combination base plate, a die combination and a die combination card plate with a variable cavity The punch is a punch with a variable core, which is composed of a punch combination base plate, a punch assembly, a punch combination card plate, a cavity cut-off assembly and a side cut combination plate. Coordinated change of mold convex, concave and auxiliary molding system. It can process a series of plastic parts of different shapes and sizes. In the plastic processing industry, it is matched with plastic molding machines to give plastic products a complete configuration and precise size tools. Due to the variety of plastic varieties and processing methods, and the complex and simple structures of plastic molding machines and plastic products, the types and structures of plastic molds are also diverse. A plastic mold is a tool for producing plastic products. It consists of several groups of parts, and this combination has a molding cavity. During injection molding, the mold is clamped on the injection molding machine, the molten plastic is injected into the molding cavity, and cooled and shaped in the cavity, and then the upper and lower molds are separated, and the product is ejected from the cavity through the ejection system to leave the mold, and finally the mold is closed again. For the next injection, the entire injection molding process is cyclic.

When the existing lawn plastic brick injection mold is used, because the lawn plastic brick is large in size and grid-like, it is a thin-walled part, and the cooling effect is poor during the injection molding process, which leads to the phenomenon that the product is difficult to demould, which is a serious problem. It affects the production efficiency and the quality of the product is not high.
