Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1, a kind of mold vacuumizes no gasket set, including panel 1, is connected with front template 2 at the top of panel 1,
2 lower horizontal of front template is equipped with rear pattern plate 3, and 3 bottom end of rear pattern plate is connected with two blocks of square iron 4 vertically, and two pieces of 4 bottoms of square iron are hung down jointly
It is direct-connected to be connected to bottom plate 5, it is vertically-mounted respectively from top to bottom inside front template 2 to have sprue bushing 8 and preceding mould mold insert 9, before sprue bushing 8 is inserted into
Inside mould mold insert 9, sprue bushing 8 and preceding mould mold insert 9 and integrated formed structure, and preceding 9 bottom end of mould mold insert extend to 2 outside of front template and
Setting in a circular table shape, preceding 9 bottom end rotary table bevel edge inclination angle of mould mold insert are 3-5 °, vertically-mounted on the panel 1 of 8 corresponding position of sprue bushing
There is injection molding nozzle 13, be bonded to each other between injection molding nozzle 13 and sprue bushing 8, is opened on 3 top of rear pattern plate of preceding 9 corresponding position of mould mold insert
Equipped with formed product chamber 12,12 inner wall top of formed product chamber matches with preceding mould mold insert 9, preceding mould mold insert 9 be inserted into product at
Inside type chamber 12, and it is interconnected between injection molding nozzle 13, sprue bushing 8 and formed product chamber 12, the installation of 12 bottom end of formed product chamber
There is ventilative steel 10, is horizontally installed with Non-return air valve 11 on the outside of the rear pattern plate 3 of ventilative 10 corresponding position of steel, breathe freely steel 10 and unidirectional gas
