The method of clamping the bottle blowing mold by using the clamp during turning

Abstract

The invention discloses a method of using a fixture to clamp a bottle blowing mold during turning. The method includes: clamping the bottom end of a half core with a left clamping device having a first elastic positioning component, wherein the first elastic positioning component is attached tightly to the peripheral face of the bottom end of the half core; clamping the bottleneck end of the halfcore with a right clamping device having a second elastic positioning component, wherein the second elastic positioning component is attached tightly to the peripheral face of the bottleneck end of the half core, and the left and right clamping devices are connected via a connection haft; using a three-jaw chuck of a lathe to clamp and hold the clamping end, coaxial to the first elastic positioning component, of the left clamping device such that an ejector pin at the tail of the lathe is inserted into an ejector pin hole in the right clamping device end of the connection shaft, and such thatcylindrical turning can be started for the half core. The method can provide better internal and external coaxiality for a half core during cylindrical turning, extrusion indentations in the surface of the half core are avoided, and processing quality and efficiency of the half core are improved accordingly.

Description

technical field [0001] The invention relates to the technical field of plastic mold manufacturing, in particular to a method for clamping a bottle blowing mold with a clamp during turning. Background technique [0002] In the beverage production industry, a variety of plastic beverage bottles are used. Most of the beverage bottles are manufactured by blow molding. The blow molding molds used to form beverage bottles mainly include Hafur type mold core, there is a rotary cavity that can shape the shape of the bottle body in the Hafur type mold core, one end of the rotary cavity is gradually reduced to form the mouth of the beverage bottle, and the Hafur type mold core is in the rotary cavity The other end of the body is provided with an outwardly expanded sinker, so that an inlaid block for forming the bottom of the beverage bottle is arranged in the sinker. When we need to turn the outer circle of the Hafur mold core, we usually use the three-jaw chuck with automatic center...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the coaxiality precision of the existing Harfur type mold core of the beverage bottle blow mold cannot be guaranteed when the outer circle is turned, and the surface of the mold core is easy to produce extrusion dents due to pressure, etc. The problem is to provide a method of clamping the blowing mold with a clamp during turning, which can effectively improve the coaxiality of the inner and outer circles of the Hafur type core when turning the outer circle, and can avoid the occurrence of cracks on the surface of the core. Extrude dents, thereby improving the processing quality and processing efficiency of the Hafur core
