Error-assembling-proofing structure for die

Abstract

The invention relates to an error-assembling-proofing structure for a die. The error-assembling-proofing structure comprises a fixed die base, a movable die base and a movable die core. The movable die core is assembled in the movable die base, and a leftward insert hole and a rightward insert hole penetrating the movable die core and the movable die base are formed in the two sides of the movabledie core. The bottom end of the leftward insert hole is provided with a leftward fool-proof positioning structure in an extending manner, and the bottom end of the rightward insert hole is provided with a rightward fool-proof positioning structure in an extending manner. The radial extending size of the leftward fool-proof positioning structure and the radial extending size of the rightward fool-proof positioning structure are different. The axial extending size of the leftward fool-proof positioning structure and the axial extending size of the rightward fool-proof positioning structure aredifferent. The fixed die base is arranged on the movable die base. Due to the error-assembling-proofing design, rotation of related inserts and ejector pins of slant product dies and curved-surface product dies can be achieved; assembling dislocation of two or more inserts, insert pins, ejector pins, sliding blocks and pitched roofs which are similar in shape and size on a die is achieved; and thefool-proof function is achieved, and the phenomenon that defective products are manufactured due to die errors in the injection molding process is avoided.

Description

Technical field [0001] The invention relates to a structure for preventing errors in mold assembly. Background technique [0002] At present, the parts assembly of the mold often has problems such as wrong parts, reverse parts, and offset parts, which have been repeated, often reworked and reworked, which delays time and wastes costs, resulting in failure to deliver on time, or in serious cases. As a result, the mold is crushed, and the repair takes a long time, resulting in high costs. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a structure for preventing errors in mold assembly. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] The structure used for error-proofing mold assembly, which is characterized by: contains a fixed mold blank, a movable mold blank and a movable mold core. The movable mold core is installed in the movable mold b...

[0002] At present, the assembly of mold parts often has problems such as wrong parts, reversed parts, and misplaced parts. These problems have been repeated, often reworked and redone, which delays time and wastes costs, resulting in failure to deliver on time. Cause mold crushing, repair takes a long time and generates high cost
