Abstract

The invention provides a mold with an exhaust function. A mold core insert is arranged in the mold, the mold core insert is composed of a plurality of arranged exhaust inserts, one end of each exhaustinsert is in communication with the bottom surface of the mold, each exhaust insert is provided with an ejector pin position, a first exhaust groove and a second exhaust groove, the ends of the firstexhaust grooves communicate with the ejector pin positions, the first exhaust grooves communicate with the second exhaust grooves, and one end of each second exhaust groove is in communication with the bottom surface of the mold. According to the mold with the exhaust function, the characteristic parts which are not prone to exhaust in a mold cavity are divided into pieces of the exhaust inserts,after a deep cavity and the narrow part of gap are separated, so that the mold-saving polishing is facilitated, mold-casting production is facilitated, the exhaust insert structure is adopted, the peripheries of the exhaust inserts are subjected to a full circle of exhaust, the exhaust space is increased, the exhaust flow is increased, the exhaust efficiency is high, and the product casting quality is improved.

Description

technical field [0001] The invention relates to the technical field of mold manufacturing, in particular to a mold with exhaust function. Background technique [0002] With the development of the mold industry, the shape of many products will become more and more peculiar, which adds a lot of difficulties to mold manufacturing. Compared with the prior art, for deep-cavity products, due to the deep mold cavity, the gas in the deep cavity is not easy to be removed during die-casting, and negative pressure is easily formed, resulting in poor product molding quality, for example, under-casting, There are problems such as bubbles or pores on the surface of the product. Therefore, how to solve the problem of difficult exhaust in the deep cavity of the die-casting mold has become a technical problem to be solved urgently. Contents of the invention [0003] The present invention aims to solve the problems described above. [0004] According to the first aspect of the present in...
