Plastic forming die

Abstract

The invention discloses a plastic forming die. The plastic forming die comprises a convex die and a concave die which are arranged at the upper part and the lower part respectively, wherein an upper base plate is arranged at the top of the convex die; a filling hole is formed in the top of the upper base plate; a plurality of locating columns are arranged on the lower surface of the convex die; a plurality of concave locating holes are formed in the upper surface of the concave die; the locating holes and the locating columns are matched; a mold core is arranged on the convex die; a cavity is formed in the concave die and at the place corresponding to the mold core; a small hole is formed in the mold core; the small hole is communicated with the filling hole. The plastic forming mold is simpler in structure, can effectively improve the match accuracy of the upper die and the lower die through match of the locating columns and the locating holes, more obviously improves the machining efficiency, and can be widely applied to the plastic molding industry with wide applicability.

Description

technical field [0001] The invention relates to a molding die, in particular to a plastic molding die. Background technique [0002] In the existing technology, the traditional plastic molding mold has technical defects that cannot be calibrated during the plastic molding process. When the upper mold falls, it cannot be accurately aligned with the lower mold, resulting in imperfect mold fit and burrs on the plastic molded product. Defects need to be reworked, resulting in an increase in the finished product. Contents of the invention [0003] Aiming at the technical problems existing in the prior art, the object of the present invention is to provide a plastic molding mold with better processing effect. [0004] The technical scheme adopted in the present invention is as follows: [0005] A plastic forming mold, comprising a punch and a die set up and down, the top of the punch is provided with an upper bottom plate, the top of the upper bottom plate is provided with a m...
