Automatic separation type isolation ring injection molding structure

Abstract

The invention discloses an automatic separation type isolation ring injection molding structure. The structure comprises a second pouring channel connected to the side portion of an isolation ring; the side portion of the isolation ring is provided with an arc-shaped pouring notch which is concave inwards and is provided with an inclined opening towards one side of the isolation ring; the second pouring channel is connected to the arc-shaped pouring notch through an ox horn pouring section; and the connection point of the ox horn pouring section and the arc-shaped pouring notch is located in the axial range of the arc-shaped pouring notch. According to the automatic separation type isolation ring injection molding structure, the arc-shaped pouring notch is formed in the side portion of theisolation ring, then the mode that the ox horn pouring section is injected into the arc-shaped pouring notch is adopted so that the connecting strength between the isolation ring and a material handle after mold opening is reduced, a product obtained after mold opening can be automatically separated under the action of a vibrating screen, and manual separation is omitted. The arc-shaped pouring notch is perpendicular to the tangent line of the ox horn pouring section as much as possible, normal injection molding is guaranteed, and the connecting face of the formed material handle and the product is small.

Description

technical field [0001] The invention relates to an injection molding structure of an automatic separation isolation ring, which belongs to the technical field of injection molding of a battery cap isolation ring. Background technique [0002] The isolation ring of the battery cap is made of plastic insulating material, which is produced by injection molding. Since the isolation ring is usually small in size, it is usually injection molded by using one material handle to produce multiple products at the same time. Such as figure 1 as shown, figure 1 It is the connection structure diagram of the isolation ring and the sprue-2 in the prior art, the end face of the sprue-2 and the isolation ring 1 ( figure 1 is the bottom surface of the figure) flush. After the product is out of the mold, the material handle needs to be separated from the product. In the prior art, manual separation is usually used, but due to the large number of spacers, the separation efficiency is not high...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide an injection molding structure of an automatic separation type isolation ring, which solves the technical problem in the prior art that the isolation ring of the battery cap needs to be manually separated from the material handle after injection molding
