Description

Dust screen mould structure

Technical Field

The utility model relates to a mould, in particular to dust screen mould structure.

Background

The mold product needs to be kept in a high-temperature and high-pressure state in the injection molding process, if the product volume is too small and the glue position is too thin, the phenomenon that the plastic begins to cool and solidify under the condition that the mold cavity is not filled with the plastic easily occurs, and the conventional mold is not provided with an active heating device, so that the plastic flowability is insufficient when the heat of the plastic in the mold cavity flowing is insufficient, the mold cavity is not filled with the plastic, and the produced product is in glue shortage. On the other hand, the smaller the product volume, the thinner the glue position, the greater the processing difficulty of the die, and the higher the processing precision requirement, and the conventional processing technology is difficult to meet the requirement of the high-precision die structure.

The common mould only has a cooling system, but does not have a heat preservation and heating device. In the injection molding process of the product, the plastic raw materials and the catalyst are heated by the injection molding machine to carry out chemical reaction to form liquid plastic, the liquid plastic is compressed to form high-temperature and high-pressure liquid plastic, the liquid plastic is injected to a casting system of a mold, the plastic flows into a mold cavity through a runner in a mold core, most energy can be dissipated in the plastic flowing process, and the temperature in the mold cavity is difficult to ensure the normal working temperature. The special structure of the product has small volume and thin glue position, which can cause insufficient pressure of the die cavity and difficult glue removal.

As a preferred technical scheme, the heating module comprises a first heating module and a second heating module, the first heating module is installed between the front mold core and the plate a, and the second heating module is installed between the rear mold core and the plate B.

As an optimized technical scheme, the ejector pin assembly comprises an ejector pin panel and an ejector pin bottom plate, and the ejector pin panel is installed on the ejector pin bottom plate.

As a preferred technical scheme, the first heating module and the second heating module both adopt a heating plate, and the two sets of heating modules are independently controlled by an independent controller.

As a preferred technical scheme, the outer side end of the panel and the outer side end of the bottom plate are both provided with a heat insulation module, the heat insulation modules are all thermal insulation plates and comprise upper thermal insulation plates and lower thermal insulation plates, the upper thermal insulation plates are arranged at the outer side ends of the panel, and the lower thermal insulation plates are arranged at the outer side ends of the bottom plate.

The utility model has the advantages that: the utility model discloses an objective condition that satisfies little volume, glue the product production that the position is thin that dust screen mould structure can. The heat-preservation heating device on the back of the front mold core and the back mold core is used for keeping the plastic cement to have enough fluidity in the filling process, so that the plastic cement can be ensured to fill the mold cavity, the product is molded smoothly, the product has better glossiness, and the product quality is higher; and its mould structure is accurate, stable in structure, and in earlier stage mould development process, mould parts machining requires rigorously, and the probability that the mould in later stage broke down is little, reduces cost of maintenance, improves production efficiency.
