In order to solve the problems, the utility model adopts the following technical proposal;
the utility model provides a backshell drawing die utensil for vacuum booster, includes cope match-plate pattern, lower bolster, goes up the mold core, lower mold core and backshell, and the mold core mounting panel is installed to the lower extreme of cope match-plate pattern, and the upper end of lower bolster is installed and is had the lower mold core mounting panel, goes up the mold core and fixes on last mold core mounting panel, goes up the mold core and mutually supports with lower mold core, and the inboard adoption of going up the mold core adopts the concave type structure identical with the backshell surface, and the surface of lower mold core adopts the protruding type structure identical with the backshell inboard, the outside of going up the mold core is equipped with the reinforcing plate, goes up the reinforcing plate and fixes on last mold core mounting panel, the outside of lower mold core is equipped with down the reinforcing plate, the upper end of backshell is equipped with the.
Preferably, the upper reinforcing plate is provided with a guide pillar, the lower reinforcing plate is provided with a guide sleeve, and the guide pillar is matched with the guide sleeve.
This setting plays the positioning action to reciprocating of mould, prevents that the skew from appearing in the in-process of backshell at processing, influences the processingquality of backshell.
Preferably, a rear shell fixing hole is formed in the upper mold core.
This setting is convenient for the installation, the fixed of backshell material, is convenient for extrude, stretch, shaping to the backshell.
Preferably, a magnet is arranged at the upper end of the rear shell fixing hole.
Due to the arrangement, the fixed rear shell material cannot fall off, and the rear shell material is convenient to reprocess.
Preferably, the upper mold core and the lower mold core are both provided with positioning holes.
This setting is convenient for go up the location when mold core and the installation of lower mold core, accuracy when guaranteeing the die holding.
The utility model has the advantages that: simple structure, convenient operation can directly stretch the design to the backshell, and tensile backshell is of high quality, and thickness is even, and work efficiency is high simultaneously, has the practicality and the universality of use.
