A Self-Adaptive Injection Mold Positioning Structure

Abstract

The invention discloses a self-adaptive injection mold positioning structure, comprising a first mounting plate, a lower injection mold, a second mounting plate and an upper injection mold, the lower injection mold is installed above the first mounting plate, and the injection molding A positioning groove is reserved on the lower mold, and a guide groove is provided on the positioning groove, and a positioning nail is arranged on the outside of the guiding groove, and the positioning nail is located on the inside of the positioning groove. A mold, and a positioning block is installed under the injection mold, an alignment groove is opened on the positioning block, and a guide nail is installed under the positioning block. The self-adaptive injection mold positioning structure can correct the misalignment between the upper injection mold and the lower injection mold by inserting the adjusting sleeve into the slot on the pole, and at the same time, the stability block and the stability slot on the clamping block The cooperation can guide and position the adjusting sleeve, which improves the mold clamping accuracy between the upper injection mold and the lower injection mold.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an adaptive injection mold positioning structure. Background technique [0002] Injection mold is a container tool used to produce plastic products. Injection mold is generally divided into upper injection mold and lower injection mold. Both upper injection mold and lower injection mold have cavities inside, while upper injection mold and lower injection mold After the mold is closed, the internal cavity is combined to form a complete cavity, which is convenient for the plastic to be poured and cooled to form, and finally the required plastic product is made; [0003] 1. The positioning accuracy of the docking and positioning of the existing injection molds through the guide rod is poor when the molds are closed, which leads to the inability to accurately dock the inner cavities of the upper injection mold and the lower injection mold, which leads to relatively rough edge...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a self-adaptive injection mold positioning structure to solve the problem that the existing injection molds proposed in the background art have poor positioning accuracy through the guide rods when the molds are closed, resulting in the upper mold being injected. The inner cavity of the injection mold cannot be accurately docked, which leads to severe burrs on the finished injection molded product, which requires manual deburring processing. The traditional injection mold is inconvenient for the upper injection mold and the lower injection mold after the mold is closed. The stable locking of the mold will cause the shape of the plastic product inside to be easily damaged, which will affect the normal use of the product, resulting in a high product scrap rate and indirectly increasing the production cost.
