Problems solved by technology

[0002] The mobile phone lens barrel adopts injection molding. In the existing injection mold, the injection material is injected between the upper mold and the lower mold through the upper mold. After molding, the upper mold moves upward. Sometimes the injection material in the sprue of the upper mold is not completely cooled. Because the temperature of the upper mold is relatively high, when the upper mold moves upward, the liquid injection plastic in the sprue is easy to fall to the lower mold, which will affect the subsequent injection molding.

Abstract

The invention discloses a high-pixel mobile phone lens tube injection mold, and relates to the technical field of injection molds. The high-pixel mobile phone lens tube injection mold comprises an upper die, a lower die, a pouring head, a runner, a forming groove and a pull needle, wherein the pouring head comprises a cup body, a cooling material injection nozzle with the upper end fixedly connected to the bottom of the cup body, a discharging channel penetrating through the bottom of the cup body and the cooling material injection nozzle, a cooling channel spirally arranged around the discharging channel, an inlet channel connected with one end of the cooling channel and a discharging channel connected with the other end of the cooling channel; the inlet channel and the discharging channel are located in the cup wall of the cup body, the end, away from the cooling channel, of the inlet channel is located on the upper edge of the cup body, and the end, away from the cooling channel, ofthe discharging channel is located on the upper edge of the cup body. The invention provides a high-pixel mobile phone lens tube injection mold, the raw material in the upper die is prevented from falling; and when the cold material is pulled out, the injection molding material cannot fall off.

Description

technical field [0001] The invention belongs to the technical field of injection molds, in particular to an injection mold for a high-pixel mobile phone lens barrel. Background technique [0002] The mobile phone lens barrel adopts injection molding. In the existing injection mold, the injection material is injected between the upper mold and the lower mold through the upper mold. After molding, the upper mold moves upward. Sometimes the injection material in the sprue of the upper mold is not completely cooled. Because the temperature of the upper mold is relatively high, when the upper mold moves upward, the liquid injection compound in the sprue is easy to fall onto the lower mold, thereby affecting the subsequent injection molding. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcoming that the raw materials in the upper mold in the prior art are easy to fall, and propose a high-pixel mobile phone lens barrel injection mo...
