Plastic mold parts cracking and cracking Solution: plastic mold material is mainly due to the stretching process, the strain over its limit and form instability. Fracture tensile strength less than 1 generated, such as test recess, park around the tree brick plastic mold, punch garden corner, surrounded by trees brick plastic mold, local excessive force and rupture. 2. The amount is less material deformation and rupture, in the bulging deformation test produced top punch rupture, or rupture elongation flange distortion caused by the inflow. 3. Aging cracks: the serious part forming hardened by strain aging embrittlement has increased, and late parts of residual stress caused by molding rupture. The material is stretched bending both folded but curved so as to produce rupture, produce more die in the ribs or mouth. 5. striped cracks. Because there are cracks caused by impurities in the material, generally parallel to the rolling direction of the sheet. Cracking Solution aspect 1. Material: plastic box with a good drawing properties of materials 2. Reduce strain areas: choose the right blank size and shape parameter adjustment drawbead adding auxiliary processes (incision, etc.) to improve the lubrication conditions modify addendum surface adjustment binder force Qingyuan plastic brick mold around the tree, surrounded by trees brick plastic mold, mold provided by Baoding Guohui Guohui Die Machinery Co.
