Hollow sphere forming mold device

Abstract

The invention discloses a hollow sphere forming mold device which comprises a lower mold base, an eccentric wheel, guide sleeves, a lower mold, guide columns, an upper mold, an upper mold fixing base, upper mold withdrawing springs, lower compression springs, lower mold withdrawing pins and an upper mold withdrawing pin, wherein the eccentric wheel is mounted on the lower mold base; a rotating shaft is mounted at one end of the eccentric wheel; the lower mold is mounted above the lower mold base through the lower mold withdrawing pins; the lower compression springs are mounted at two ends of the lower mold withdrawing pins through hinge pins; the guide columns are mounted at two ends of the lower mold through the guide sleeves; the upper mold fixing base is mounted on the guide columns; the upper mold is mounted below the upper mold fixing base through the upper mold withdrawing pin; the upper mold withdrawing springs which are connected with the upper mold withdrawing pin are further mounted in the middle of the upper mold fixing base. As the elastic withdrawing pins are respectively added into the upper mold and the lower mold of the hollow sphere forming mold device, materials are easy to withdraw, no extra manual work is needed, the working efficiency is improved, and the loss and the cost are reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a hollow ball molding die device. Background technique [0002] The hollow ball is an indispensable intermediate connector in the spherical railing. The current mold is difficult to return during production and needs to be manually returned. Not only the production efficiency is low, but also the labor intensity of the workers is increased. For this reason, combined with the original mold, The mold needs to be redesigned. The production process of the hollow ball is to put a certain length of round tube into the mold, and form a hollow ball by extrusion molding. During the molding process, due to extrusion deformation, the finished product will stick to the mold and cannot be taken off automatically. It needs manual prying. Only by prying the rod can the mold be removed, and it is necessary to pry once to produce a hollow ball, which increases the extra labor i...

The production process of the hollow ball is to put a certain length of round tube into the mold, and form a hollow ball by extrusion molding. During the molding process, due to extrusion deformation, the finished product will stick to the mold and cannot be taken off automatically. It needs manual prying. The mold can only be removed by prying the stick, and it needs to be pried once to produce a hollow ball, which increases the extra labor intensity
