[0023] Specific implementation: when in use, the operator holds the base 15, inserts the dovetail slider 16 into the dovetail groove 11, and pushes the bracket 14 downward, and the bracket 14 drives the dovetail slider 16 to move downward in the dovetail groove 11, and then The base 15 moves downward, and the downward movement of the base 15 drives the automatic exhaust assembly 2 to move downward. When the automatic exhaust assembly 2 moves to the front of the exhaust hole 4, the operator tightens the positioning bolt 13, and the positioning bolt 13 will The dovetail slider 16 is fixed in the dovetail groove 11, and the base 15 is fixed on the lower mold base 3, thereby realizing the quick assembly function of the device and being convenient for operators to operate.
[0024] Then the exhaust hole 4 squeezes the rubber plug 21, the rubber plug 21 squeezes the push rod 24 to move in the guide sleeve 22, the push rod 24 moves and squeezes the spring 23, so that the spring 23 is ...

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...
