Abstract

The invention discloses a crescent cavity injection mold. The crescent cavity injection mold comprises a front mold core base plate, a front mold core plate, a mold cavity plate, a rear mold core plate, a rear mold core base plate, main runner holes and transverse runners, wherein the front mold core base plate, the front mold core plate, the mold cavity plate, the rear mold core plate and the rear mold core base plate are sequentially stacked from top to bottom; each of the front mold core plate, the mold cavity plate and the rear mold core plate is provided with two insert cavities in left-right symmetry, the insert cavities are of crescent shapes in left-right symmetry, and the recessed parts of the crescent shapes are opposite to each other; two front mold inserts are embedded into the front mold core plate, and two rear mold inserts are embedded into the rear mold core plate; the front mold inserts, the rear mold inserts and the mold cavity plate form a product cavity. The crescent cavity injection mold is used for producing crescent injection molding products and is high in machining precision, capable of producing two products at the same time and high in machining efficiency.

Description

technical field [0001] The invention relates to the field of plastic product mold structures, in particular to an injection mold structure with a crescent-shaped cavity. Background technique [0002] Injection mold is an important process equipment for the production of various industrial products. With the rapid development of the plastic industry and the promotion and application of plastic products in aviation, aerospace, electronics, machinery, ships and automobiles and other industrial sectors, injection molds are widely used in various industries. middle. The traditional injection mold consists of a movable mold and a fixed mold. The movable mold is installed on the moving template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During 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 and the fixed mo...
