Mould design of multiple parting surface hollow storage bucket based on inner and outer side linkage core-pulling
According to the performance and process characteristics of the product,the product structure and process of the hollow storage bucket were analyzed.Based on the different positions of hollow and bucket groove,the mould structure of three-layer parting surface were designed to realize the motion control of each forming part.In order to improve molding quality and save mould space,an explosive sliding block core-pulling mechanism on the fixed die side was cleverly designed.Because the concave shape of the bottom of the product was located at the bottom of the fixed die,the space was narrow and the power source was lacking,so the floating inclined top mechanism of the cavity side was designed at the bottom of the fixed die,and the core-pulling action of the bottom side concave was completed.A core-pulling mechanism with inner and outer linkage was designed in the moving die for the large barrel groove with inner and outer rounded edges.After the mould is put into production,each core-pulling mechanism works smoothly,the product demoulding smoothly,and the expected purpose is achieved.
