Problems solved by technology

[0002] The shape of the injection molded product is a long strip product, and the product is formed by two injection molding methods, the first injection of A plastic, and the second injection of another B plastic; when using a commonly used two-color injection mold to form this product, the main The problem is that it is impossible to guarantee the orderliness of the molecular arrangement of the second plastic, and to form an apparent quality with consistent molecular orientation. The second is that the bonding between the two layers of plastic is not firm and it is easy to fall off. Launched a new secondary injection molding unit

Abstract

The invention provides a long-strip-shaped injection molded part. The long-strip-shaped injection molded part is manufactured from a secondary injection molding mold, and the secondary injection molding mold comprises parts such as a side-edge positioning ring, a sprue bush fastening screw, a mold cavity insert, an upper semi-ring sprue bush, a lower semi-ring sprue bush, a sprue bush positioningpin, a reset rod spring, a reset rod, a supporting column, a flow channel jacking rod, an A rubber jacking rod and a skeleton body lower positioning insert. Through side-edge type pouring system parts, the technical effect that it is ensured that molten material flow molecules flowing out of a main runner can be poured into a molding mold cavity without greatly changing the direction of the moltenmaterial flow molecules is achieved, and the beneficial effect that the main runner and a main flowing channel can maintain flow orientation consistency of B rubber injection molded flow molecules.
