Compression or injection mold useful in e.g. automobiles and trains, comprises a matrix assembly having a close-fitting side, an assembly of low-base core carrier with a core, and an assembly of pieces joined together by mechanical welding

摘要

The compression or injection mold (101) comprises a matrix assembly (102) having a close-fitting side, an assembly (103) of low-base core carrier (108) with a core (109), and an assembly of pieces joined together by mechanical welding. The core is present in the form of a complementary close-fitting part passing through matrix assembly. The pieces have a simple geometry, and are present in the form of plate, cylindrical plots or parallelepiped. The lower base has lower parts and ribs same as that of a mold made of steel block, and forms a cage for the ejection of molded parts.

The core is present in the form of a complementary close-fitting part passing through matrix assembly. The pieces have a simple geometry, and are present in the form of plate, cylindrical plots or parallelepiped. The lower base has lower parts and ribs same as that of a mold made of steel block, and forms a cage for the ejection of molded parts. The mold further comprises vertical reinforcement plates, gussets of reinforcement plots, replacement ribs made of steel, plates for covering a system of plots, and plates opposite to that of core carrier. The core carrier comprises an interior plate having a central opening for passing the ejection plate and carrying a rising wedge so as to guide the mechanical connection with movable core and recentering of the lower base assembly, an intermediate plate comprising side openings for passing the rising wedge, and an upper plate. Independent claims are included for: (1) a base part and/or a core-carrier of mold; and (2) a process for the fabrication of a mold.
