Injection mold for automobile grille

Abstract

The invention provides an injection mold for an automobile grille, wherein the injection mold comprises an upper mold and a lower mold which are matched with each other; the upper mold and the lower mold are respectively provided with mold cavities matched with each other to form the injection molding automobile grille. The lower mold includes a pair of semi-molds which are symmetrically arranged;each semi-mold has a number of gate combinations distributed close to the lateral border of the semi-mold, and each gate combination has a main runner and at least two branch runners connected with the main runner. The gate combinations comprise a first gate combination located at the side part along the lengthwise direction of the lower mold, and a second gate combination and a third gate combination arranged in the front direction and the rear direction. The injection mold for the automobile grille has balanced glue feeding in the process of injection molding of the automobile grille, and can effectively improve the product quality of the automobile grille.

Description

technical field [0001] The invention relates to an injection mold, in particular to an injection mold for an automobile grid. Background technique [0002] Usually, the automobile grille is manufactured and produced through the mold injection molding process, because the grid structure in the middle area of ​​the automobile grille is usually relatively complicated, and the appearance quality requirements of the automobile grille are relatively high. With the development of injection molding technology, people have higher and higher requirements for the surface quality of injection molding products. It is required that the surface of injection molding products have no weld marks, no flow marks, and high surface gloss. Traditional molds can no longer meet such requirements. In the injection molding process of automobile grille, the direct pouring gate design is generally adopted, and the gate is set on both sides of the automobile grille, but the length of the automobile grill...

AI Technical Summary

Problems solved by technology

With the development of injection molding technology, people have higher and higher requirements for the surface quality of injection molding products. It is required that the surface of injection molding products have no weld marks, no flow marks, and high surface gloss. Traditional molds can no longer meet such requirements.

In the injection molding process of automobile grille, the direct pouring gate design is generally adopted, and the gate is set on both sides of the automobile grille, but the length of the automobile grille is relatively long, and the length of the runner is relatively long, resulting in the molten plastic material filling There is a temperature deviation when entering the cavity, which leads to lower product quality; in this way, the development of injection molds is relatively difficult, and there is still a risk of defects on the product surface,
