injection mold

Abstract

The invention provides an injection mold used for injection molding of a workpiece. The injection mold comprises an upper mold body, a lower mold body, a plastic inflow mechanism and a jacking material. The upper mold body comprises an upper mold base and an upper mold core arranged on the upper mold base. The lower mold body comprises a lower mold base and a lower mold core arranged on the lower mold base. The upper mold core and the lower mold core are matched to form a mold cavity. The plastic inflow mechanism comprises a wedge-shaped block, a plastic inflow sliding block and an angle pin. The wedge-shaped block is fixed to the upper mold base, the plastic inflow sliding block is arranged on the lower mold core in a sliding mode and matched with the inclined face of the wedge-shaped block, a plastic inlet is formed in the end, facing the mold cavity, of the plastic inflow sliding block, and therefore the plastic inflow sliding block can inject melted plastic into the mold cavity. The angle pin movably penetrates through the wedge-shaped block and the plastic inflow sliding block, the upper mold base can drive the wedge-shaped block and the angle pin to move away from the lower mold base together, the plastic inflow sliding block moves away from the mold cavity under the effect of the angle pin, and the jacking mechanism is movably arranged in the lower mold body and used for jacking the formed workpiece out of the mold cavity. The appearance quality of the workpiece obtained after injection molding is effectively improved through the injection mold.

Description

technical field [0001] The invention relates to a mold, in particular to an injection mold. Background technique [0002] With the rapid development of the manufacturing industry, injection molding technology has been widely used in mobile terminals, household appliances, automobiles and other industries. The existing injection molding process first injects molten plastic into the mold cavity, and after cooling and solidifying, a product with a specific shape can be formed, and then the product and the residual plastic are ejected through the ejector mechanism. However, as the market has higher and higher requirements on the appearance of products, the corresponding injection mold structure is also becoming more and more complicated. The traditional way of using a single hot runner to feed the mold will lead to uneven glue feeding, which in turn will affect the appearance quality of the injection molded product. Contents of the invention [0003] In view of this, it is n...
