Exhaust structure of mold

Abstract

The invention provides an exhaust structure of a mold. The exhaust structure comprises a dovetail groove, a fixed plate, a positioning bolt, a support, a dovetail sliding block, a rubber plug, a guidesleeve, a spring and an ejector rod; the dovetail groove is formed in the position, on the left side of an exhaust hole, of the front end face of a lower mold holder, the fixed plate is arranged on the upper end face of the support, the positioning bolt is arranged in the middle of the fixed plate, the rear end of the positioning bolt extends into the dovetail groove, the support is fixed to therear surface of the base, the dovetail sliding block is fixed to the rear end face of the support, the dovetail sliding block is assembled in the dovetail groove. Through the design, rapid assemblingof the structure is achieved, the rubber plug is fixed to the rear end of the ejector rod, the guide sleeve is arranged in the middle of the rear surface, the spring is assembled on the front side face in the guide sleeve, the rear end of the spring is connected with the ejector rod, and the ejector rod is assembled in the guide sleeve. Through the design, the automatic seal function of the exhaust hole is achieved, and the structure is novel, convenient to assemble, good in use flexibility, good in stability and high in reliability.

Description

technical field [0001] The invention relates to an exhaust structure of a mold, which belongs to the field of mold technical equipment. Background technique [0002] The mold exhaust structure in the prior art is simple, and cannot be quickly assembled, and the flexibility of use is not high; the mold exhaust structure in the prior art cannot seal the vent hole when it is not in use, and dust can easily enter through the vent hole In the mold cavity, it affects the pass rate of the workpiece, so there is an urgent need for a mold exhaust structure to solve the above-mentioned problems. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a mold exhaust structure to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure, is easy to assemble, has good flexibility in use, good stability, and reliability. high. [0004] In order to achieve...
