Problems solved by technology

[0003] As far as the injection mold is concerned, due to the imperfect technology of the current injection mold, it is inevitable that air will enter during mold clamping and injection molding, which will cause air bubbles in the plastic fluid, and the bubbles cannot be completely discharged, which will make the surface of the injection molded part There are hollow convex balls visible to the naked eye, which will greatly reduce the quality of injection molded parts

Abstract

The invention discloses an injection mold. The injection mold structurally comprises a top plate, an upper mold body, a bubble shaking device, a base, side square blocks, an ejection mechanism and a lower mold body, wherein the bottom of the top plate is connected with the upper mold body, the upper mold body is located above the lower mold body, the lower mold body is connected with the base through the side square blocks, the ejection mechanism is arranged between the two side square blocks, the ejection mechanism is connected with the base, and the ejection mechanism is further matched withthe lower mold body. Compared with the prior art, the injection mold has the beneficial effects that through combined arrangement of a groove, a knocking block, a sponge sleeve, a rotating assembly,a linkage gear, a transmission belt, a base body, a second transmission mechanism, a first transmission mechanism and a limiting ring, the side face of the lower mold body is intermittently knocked sothat injection molding slurry in a mold cavity of the lower mold body can generate resonance; and the bubbles are broken by vibration through resonance, so that the problem that hollow convex balls exist in the formed injection-molded part due to the fact that the bubbles cannot be completely discharged can be solved, and the quality of the formed injection-molded part can be improved.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to an injection mold. Background technique [0002] Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. [0003] As far as the injection mold is concerned, due to the imperfect technology of the current injection mold, it is inevitable that air will enter during mold clamping and injection molding, which will cause air bubbles in the plastic fluid, and the bubbles cannot be completely discharged, which will make the surface of the injection molded part There are hollow convex balls visible to the naked eye, which will greatly reduce the quality of injection molded parts.
