Description

Straight top insert structure Technical Field The utility model relates to the technical field of mold structures, in particular to a straight top insert structure. Background In the injection molding process, because the compact bone position structure of the product leads to abnormal increase of packing force, the traditional inclined ejection mechanism is easy to enable the product to synchronously retreat along with the inclined ejection during ejection, and the surface of the product is dragged and the demolding efficiency is low. In the prior art, although the straight-top insert is adopted for auxiliary ejection, the straight-top insert is limited by the defects of an insert fixing mode and structural matching, the movement of a product along with the inclined top cannot be effectively blocked, the product is easy to drag under the condition, the production yield and the production efficiency are seriously affected, and therefore, the straight-top insert structure is provided. Disclosure of utility model The utility model aims to overcome the existing defects, provides the straight-top insert structure, limits the position of a product, avoids dragging the product, and can effectively solve the problems in the background technology. In order to achieve the aim, the utility model provides the technical scheme that the straight top insert structure comprises a rear die and an inclined top insert assembly; The rear die is internally provided with an inclined guide opening, and a straight top insert component is arranged in the inclined guide opening; The oblique top insert assembly comprises a guide frame, a connecting bolt and an oblique top insert, wherein an oblique hole is formed in the middle of the guide frame, the oblique top insert is connected in the oblique hole in a sliding mode, the upper end of the oblique top insert is located in the oblique guide opening, four corresponding threaded holes are formed in the edge of the guide frame, the connecting bolt is connected to the inner threads of the threaded holes, the straight top insert assembly is connected with the upper end of the oblique top insert, and the connecting assembly is connected to the lower end of the oblique top insert, and drives a product to move through the arrangement of the oblique top insert assembly. Further, straight top mold insert subassembly contains spread groove, straight top mold insert, product and round pin axle, spread groove and shaping groove have been seted up to the upper side portion of oblique top mold insert, the shaping groove is located the top of spread groove, the inside of shaping groove is provided with the product, straight top mold insert has been placed to the inside of spread groove, straight top mold insert is laminated mutually with the inner wall of slant guiding mouth, the pinhole has been seted up to the upside of oblique top mold insert, the inside of pinhole is provided with the round pin axle, the lower extreme of round pin axle is laminated mutually with the upside of straight top mold insert, the upside of product is provided with the connecting hole, the round pin axle is located the inside of connecting hole, supports the product through setting up straight top mold insert subassembly.
