Hot and cold dual-station rotary rapid thermal cycle injection mold and molding method

Abstract

The invention provides a hot-and-cold double-station rotary rapid heat cycle injection mould, comprising a fixed mould module and a movable mould module. The fixed mould module comprises, arranged in sequence, a cavity plate, a cavity retaining plate, a fixed mould fixing plate and a fixed mould rotating device driving the cavity plate to rotate on the cavity retaining plate; the movable mould module comprises, arranged in sequence, a core plate, a core retaining plate, a movable mould fixing plate and a movable mould rotating device driving the core plate to rotate on the core retaining plate; the front surface of the cavity plate and the front surface of the core plate define two mould cavities through enclosure; and a heating device and a cooling device are arranged in both the cavity retaining plate and the core retaining plate, and in a closed state of the mould, the heating device heats one of the two mould cavities while the cooling device cools the other of the two mould cavities. The invention also provides a hot-and-cold double-station rotary rapid heat cycle injection moulding method using the mould. The mould and method provided by the invention have high heating and cooling rates and high production efficiency, enables good temperature homogeneity to be obtained on the surface of the cavities and are convenient for industrial application.

Description

technical field [0001] The invention relates to a polymer material forming mold, in particular to a hot and cold double station rotary rapid thermal cycle injection mold and a forming method. Background technique [0002] Plastic injection molding has the characteristics of high production efficiency, low cost, strong adaptability and product diversification. Injection molded products are widely used in the fields of information, automobiles, home appliances, aerospace and national defense. In recent years, plastic products are developing in the direction of high performance, high precision, low cost, lightweight and green, which makes the conventional injection molding process is facing increasingly severe challenges, and it is becoming more and more difficult to meet the requirements of the development of modern injection molding industry. For this reason, in recent years, the industry has introduced a new injection molding technology—rapid thermal cycle injection molding,...
