Drawings
Fig. 1 is the structure schematic diagram of the injection foaming mold with the shaft end limiting structure forming function.
Detailed Description
The utility model provides a foaming mold moulds plastics that possess axle head limit structure forming function. The technical solution of the present invention will be described in detail below with reference to the accompanying drawings so as to be easier to understand and grasp.
An injection foaming mold with a shaft end limiting structure forming function, as shown in fig. 1, comprises two mold bases 1 which are vertically arranged oppositely and provided with opening and closing displacements.
Arbitrary die holder 1 includes at least one injection molding chamber groove 2, and injection molding chamber groove 2 is including being used for the fashioned half type groove cavity 3 of membrane cover, and the both ends of the half type groove cavity 3 of membrane cover are equipped with respectively and are used for carrying out tip limit bearing's semicircle type bearing part 5 to paper spool 4, and the one end of the half type groove cavity 3 of membrane cover is equipped with a plurality of protruding type portions 6 of circumference evenly distributed.
Under two die holders 1 looks amalgamation state, semicircle type load-bearing part 5 splices mutually and forms end position centre gripping station, and the paper spool 4 bridges between two end position centre gripping stations, forms the membrane cover die cavity of moulding plastics between the periphery wall of membrane cover half die cavity and paper spool.
The specific implementation process and principle description are as follows:
before injection molding operation is carried out, the two die holders 1 are in a die splitting state, and at the moment, the paper roll shaft 4 is placed in the injection cavity groove 2 of the die holder 1 at the bottom, so that two ends of the paper roll shaft 4 are respectively supported on the semicircular bearing parts 5.
Then carry out the compound die operation of two die holders 1, the compound die in-process, the 5 looks one-to-one amalgamations of semicircle type load-bearing part of two die holders 1 to the realization is to the both ends centre gripping lock solid of paper spool 4, and the half type vallecular cavity of membrane cover 3 is integrative mutually spliced, forms the membrane cover die cavity of moulding plastics between the periphery wall of half type vallecular cavity of membrane cover 3 and paper spool 4, through pouring into the expanded material in the die cavity of moulding plastics to this membrane cover, thereby directly form the membrane cover on the paper spool, need not the artifical cup joint in later stage.
What need explain is, through the design of a plurality of protruding type portions 6 for the one end of the foaming type membrane cover after the shaping forms wave type ring end, thereby the interference of the chuck of being convenient for cup joints the cooperation, and form the ring platform portion between wave type ring end and the foaming type membrane cover, thereby realize the spacing butt of axial to the chuck, satisfy the loading position stability demand of chuck.
