Problems solved by technology

[0005] Existing metal stamping dies have the characteristics of "one-off" in use, and can only be stamped as objects of the same size, and stamping parts with inconsistent sizes cannot be stamped, and the cost is high; if the parts are damaged during the process It cannot be repaired; at the same time, for traditional metal molds, if you want to change the size, you need to meet the high temperature environment for pouring, which has high environmental requirements
Today's rapid parts resin stamping dies also have the characteristics of "one-off" in use. The fundamental reason is that the resin materials used by most mold manufacturers are filled with hardening materials such as silica sand, and do not have mechanical reprocessing capabilities. Single parts After the stamping is completed, it can only be discarded

Embodiment Construction

[0040] Such as figure 1 As shown, a manufacturing method of a recyclable resin stamping die, its specific implementation steps are as follows:

[0041] (1) Selection of the master mold: first classify the parts according to the purpose, select the largest size of the same kind of parts to design the mold, and the mold manufactured according to this size is used as the master mold; the master mold is a resin stamping mold for rapid parts, master model for use;

[0042] (2) Refer to image 3 , Determine the correction area: After the master mold is used, after comparing it with the new parts of the same kind, determine the correction area of ​​the master mold according to the difference between the stamping surface shape of the new parts of the same kind and the master mold;

[0043] (3) Refer to Figure 4 , Modification of the punch: use a cutting machine to remove the excess resin material from the protruding part of the punch of the master die until the surface of the punc...

Abstract

The invention discloses a method for manufacturing recyclable resin stamping dies. The method mainly aims to solve problems of single use, high manufacturing cost and incapability of being repaired in case of damage of an existing stamping die. The method includes selecting female dies; comparing like novel components to the female dies to determine correction areas; correcting the female dies; preparing resin materials and filling the female dies with the resin materials; machining new dies to obtain the new dies on the basis of the female dies. The method has the advantages that purposes of locally modifying and integrally updating resin stamping dies can be achieved on the premise that the integral structures of the resin stamping dies are not changed, and accordingly the dies can be recycled.

Description

technical field [0001] The invention relates to a method for manufacturing a recyclable resin stamping die, which belongs to the field of die manufacturing. Background technique [0002] A mold is a tool used to shape objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. It is used under the action of external force in blanking, forming stamping, die forging, cold heading, extrusion, pressing of powder metallurgy parts, die casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. Blanks become tools for workpieces of specific shape and size. [0003] At present, my country's mold industry mainly relies on metal materials such as steel, cast iron, aluminum and alloys to complete the mold. [0004] Resin stamping die has the characteristics of ...
