Novel half block automatic opening mold structure

Abstract

The invention relates to a novel half block automatic opening mold structure, which is composed of half strips, a spring, guide wedges, a wedge, bolts, a lower mold and a middle mold; the spring is located between the two halves; the guide wedges are located at the left and right position of the halves; the entire half strips cooperate through the wedge; the guide wedges and the wedge are assembled on the lower mold by a bolt; and the middle mold is arranged on the lower mold. The guide wedges play the role of guiding and cooperating. The pre-pressure length of the spring can be chosen according to the outer diameter of the whole structure. The angles of the guide wedges and the length of a cooperating surface can be designed according to the outer diameter of the whole structure. The invention has the advantages of high production efficiency and low labor intensity of workers, can realize the functions of automatic bounce and automatic clamping of the half strips, omitting of manual prying and closing of the half, and no trimming connection between the two half products and reduction of auxiliary production time.

Description

technical field [0001] The invention belongs to the field of half block mold structures, and in particular relates to a novel half block mold structure for automatic opening. Background technique [0002] When the current gasket mold is vulcanized, the mold adopts the half-injection and half-molding structure of the half-injection mold. When the product is released from the mold, the middle mold is lifted, and the worker needs to use a tool to separate the pry opening between the half-holes to take the product, because the product cavity is not designed for a single When the material cup is out of the mold, the product between the two haffles and the flash are connected together. It is necessary to separate the flash with a tool before the mold can be released. Vulcanization, in the whole process, the auxiliary time is too long and the efficiency is low. Therefore, the existing mold structure can no longer meet the actual production needs, and there is an urgent need for a ...

[0002] When the current gasket mold is vulcanized, the mold adopts the half-injection and half-molding structure of the half-injection mold. When the product is released from the mold, the middle mold is lifted, and the worker needs to use a tool to separate the pry opening between the half-holes to take the product, because the product cavity is not designed for a single When the material cup is out of the mold, the product between the two haffles and the flash are connected together. It is necessary to separate the flash with a tool before the mold can be released. Vulcanization, in the whole process, the auxiliary time is too long and the efficiency is low

Therefore, the existing mold structure can no longer meet the actual production needs, and there is an urgent need for a kind of Huff bar that can automatically spring open and automatically close the mold, without the need for workers to manually pry and close the Huff, and there is no flying between the two Huff products. Hover block automatic opening of mold structure for edge joining and reduced production auxiliary time
