Abstract

The invention discloses a novel inclined guide post structure which is applied to injection molding opening and closing of an injection mold and fixedly arranged on a front mold of the injection mold. The oblique guide post fixing seat is inserted in a designated position of the front die and fixed through bolts, a guide post installation groove is formed in the inner side face of the oblique guide post fixing seat, a square oblique guide post is fixedly installed in the guide post installation groove and protrudes out of the inner side face of the oblique guide post fixing seat, an oblique guide post guide groove corresponding to the square oblique guide post is formed in an injection molding sliding block in the injection mold, and one side of the square oblique guide post protruding out of the oblique guide post fixing seat is slidably installed in the corresponding oblique guide post guide groove. The structure design is simple, the condition that the height of the sliding block is set higher is fully utilized, the setting angle of the square inclined guide post is not limited, the running stroke of the sliding block is increased, the demolding of a product on a die is facilitated, the structure between the sliding block and the die is relatively stable due to the square inclined guide post, the driving component of the sliding block is reduced, and the cost is greatly saved.

Description

Novel oblique guide pillar structure Technical Field The invention relates to the technical field of injection mold core pulling, in particular to a novel inclined guide pillar structure. Background With the rapid development of the plastic industry, various tools and products used in daily production and life, such as ships, automobiles, screws, buttons and shells of various household appliances, are not closely related to plastic products. The injection mold is an important technological equipment for producing various plastic industrial products, and is also a tool for endowing plastic products with complete structures and precise dimensions. Injection molding is a processing method used for mass production of parts with complex shapes, and specifically refers to that heated and melted plastic is injected into a mold cavity formed by buckling a movable mold and a fixed mold through an injection molding machine at high pressure, and a formed product is obtained after cooling and solidification. The product needs demolding after molding, and under normal conditions, when the demolding sliding block stroke is relatively large, the sliding block is driven by an oil cylinder to perform core pulling action, the sliding block is guided by means of the inclined guide posts, but due to the fact that the sliding block stroke is large, the length of the guide distance of the inclined guide posts is increased, the occupied space of the inclined guide posts arranged in a mold is increased, and due to the fact that the existing inclined guide posts are fixedly arranged on a rear mold and are connected with the sliding block only through wall space in a sliding mode, the guiding effect is poor, meanwhile, the length of the existing inclined guide posts is long, and after the sliding block stroke is large, the inclined guide posts are easy to break due to the problem of moment. Disclosure of Invention The invention aims to solve the defects of the prior art and provides a novel inclined guide pillar structure. The technical scheme includes that the novel oblique guide post structure is applied to injection molding opening and closing of an injection mold, the novel oblique guide post structure is fixedly installed on a front mold of the injection mold and comprises an oblique guide post fixing seat and a square oblique guide post, the oblique guide post fixing seat is inserted in a designated position of the front mold and is fixed through bolts, a guide post installation groove is formed in the inner side face of the oblique guide post fixing seat, the square oblique guide post is fixedly installed in the guide post installation groove and protrudes out of the inner side face of the oblique guide post fixing seat, an oblique guide post guide groove corresponding to the square oblique guide post is formed in an injection molding sliding block in the injection mold, and one side of the square oblique guide post, protruding out of the oblique guide post fixing seat, is slidably installed in the corresponding oblique guide post guide groove. Further, an inserting protruding block used for limiting and fixing the front die is arranged on the outer side of the inclined guide post fixing seat, and a guide sliding block is further arranged on the side wall of the inclined guide post fixing seat. Further, the cross section of the square oblique guide post is of a rectangular structure, the upper end of the square oblique guide post is arranged in a step shape, and the square oblique guide post is integrally formed and is convenient to be embedded and clamped with the guide post mounting groove. Further, the setting angle of the square inclined guide post is 30-60 degrees with the vertical line, and the sliding stroke between the square inclined guide post and the injection molding sliding block is inversely proportional to the setting angle of the square inclined guide post. Further, one end of the upper inclined guide post guide groove of the injection molding sliding block, which is close to the front die, is upwards arranged in a flaring shape. Compared with the prior art, the invention has the advantages that the structure design is simple, the height of the sliding block is fully utilized, the setting angle of the square inclined guide post is not limited, the setting length of the square inclined guide post can be prolonged, the running stroke of the sliding block is increased, the demolding of a product on a die is facilitated, the structure between the sliding block and the die is relatively stable, the square inclined guide post can drive the sliding block to run only by driving the square inclined guide post along the inclined guide post guide groove through the die opening of the front die, and the cost is greatly saved.
