Abstract

The invention discloses an injection mould with a positioning function. The injection mould comprises an upper mould, a lower mould, a positioning shaft, a positioning ring and guide posts, wherein a circular blind hole is formed in the middle of the lower mould; a ring-shaped clamping slot is formed, in a peripheral direction, in the middle of the blind hole; a circular groove is formed in the bottom of the upper mould; a ring-shaped thin wall is formed between the circular groove and the outer wall of the upper mould; the upper mould is clamped in the ring-shaped clamping slot through the ring-shaped thin wall so as to position the upper mould and the lower mould in a height direction; the positioning ring is arranged at the outer side of the positioning shaft in a sleeving mode; the positioning shaft is arranged between the upper mould and the lower mould; and the guide posts are uniformly distributed in the form of a ring along the end surface of the upper mould. In this way, the injection mould with the positioning function disclosed by the invention can be used for accurately positioning the upper mould and the lower mould and guaranteeing the manufacturing quality of products in the mould, is simple and reliable in positioning, convenient in dismounting, and especially has a zero-deflection positioning function.

Description

technical field [0001] The invention relates to an injection mold, in particular to an injection mold with a positioning function. Background technique [0002] With the application of plastic products in people's life more and more. The development and production of injection molds has also increased. The injection mold consists of a moving mold and a fixed mold. The moving mold is installed on the movable template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the movable mold and the fixed mold are closed to form the gating system and the cavity, and the movable mold and the fixed mold are separated to take out the plastic product when the mold is opened. [0003] In the process of using the mold, people must first clamp and fix the mold, and then use the upper mold and the lower mold to cast or press the product. Because the upper mold and the lower mold have a certain...
