Glass molds for bottles and cans that open the bottle body and shoulders step by step

Abstract

The invention discloses a bottle glass mold adopting separate mold opening for a bottle body and a bottle shoulder. The bottle glass mold comprises two symmetrical half molds, wherein each half mold comprises a body and a top cover which are arranged at an interval, a shoulder part molding block capable of moving upwards and downwards is arranged in the interval, an elastic piece is arranged between the bottom surface of the shoulder part molding block and the body, a stamping positioning hole is formed in the top cover, a stamping positioning dowel is arranged on the top surface of the shoulder part molding block and penetrates the stamping positioning hole to form a bulge, and the height of the bulge is larger than or equal to the thickness difference of the interval and the shoulder part molding block. According to the mold, the bottle body and the bottle shoulder part are subjected to separate mold opening automatically, manual intervention is not required, the combination accuracy is high, the appearance quality of a finished product is improved, and the processing efficiency is increased.

Description

technical field [0001] The invention relates to a glass mold for bottles and cans, in particular to a glass mold for bottles and cans in which a bottle body and shoulders are molded step by step, which is mostly used in the production of cosmetic bottles and cans, and belongs to the technical field of glass mold manufacturing. Background technique [0002] Relatively high-end cosmetic bottles and jars, such as glass bottles and jars such as perfume bottles, have complex appearance shapes. In addition to the conventional decorative patterns such as patterns and edges on the surface of the bottle body, the design of the shoulders of the bottles is also more complicated. Ordinary bottles and cans are designed with concave and convex patterns on the bottle body. Usually, a suitable parting line can be found so that the entire pattern can be arranged on the same half-mould, and there will be no irregular pattern of concave and convex in the parting direction of the two half-moulds...

AI Technical Summary

Problems solved by technology

This makes the left and right two-part mold that can be designed simply, but cannot be opened smoothly because of the concave-convex surface of the shoulder ring.

At this time, the shoulder mold must be designed separately to separate it from the bottle body mold, which makes the entire mold combination very cumbersome and requires high assembly and combination, otherwise it is easy to have bottle body defects and affect the yield
