What is "saving mould" in mould industry?
Saving die is the trimming of the accuracy of the male and female dies. It is generally used in the dies with high accuracy and operated by CNC milling machine. The main design software is UG.
The real economy of the industry has accelerated to decline, a large number of mold factories are in recession, and the Provincial mold polishing shop has accelerated the speed of disappearance. At present, the salary is not optimistic.
Mold saving means that some of the molds are spent and repaired with tools.
When a new mold starts to be processed, it shall be cleaned with hot water (kerosene) first, and then all oil stains and unnecessary substances shall be wiped with alcohol, so that when the mold is hit with oilstone, the oilstone surface will not be stuck with dirt or lose the cutting function
matters needing attention:
1. During die saving, the bottom corner, bone pit and dead corner of the die shall be saved first, and then the protruding position and the large plane part of the die shall be three to four pieces embedded to form a die. Only coarse or spark marks shall be punched along the edge of individual die mouth, and then all the die pieces shall be clamped to be smooth, and the position of the die mouth will be slightly smooth when the plastic part is pulled out.
2. For flat or high protruding die, it is necessary to use flat steel sheet and red lead to check whether the die is uneven or has a bad condition of reverse mouth after roughening. If there is any uneven finished product, it will be stuck or dragged.
3. If the mold piece is a plane and it may be a sealing position somewhere, we can use double-sided adhesive paper to paste sand paper on the edge of the mold that we don’t want to save, so as to ensure that we don’t save the place that we shouldn’t save.
4. When pressing the sandpaper mould with copper or bamboo pieces, remember that the sandpaper should not be larger than the area of the tool, and the area that should not be hit should not be hit to the round mouth by more sandpaper or changed the uneven status quo.
5. When processing with copper or bamboo pieces, the shape of the tool should be similar to that of the mold, so as to avoid the deformation of the mold.
Extended data:
According to the different materials formed
Hardware mold, plastic mold, and its special mold.
Hardware mold includes: stamping die (such as punching die, bending die, drawing die, turning die, shrinkage die, relief die, bulging die, shaping die, etc.), forging die (such as die forging die, upsetting die, etc.), extrusion die, extrusion die, die casting die, forging die, etc;
The non-metallic mould includes plastic mould, inorganic non-metallic mould, sand mould, vacuum mould and paraffin mould.
Among them, with the rapid development of polymer plastics, plastic mold is closely related to people’s life. Plastic mold can be generally divided into: injection molding mold, extrusion molding mold, gas assisted molding mold, etc.
