Description
Technical field
This utility model relates to a kind of vacuum mold suitable in small size synthetic resin work pieces process field。
Background technology
In recent years, along with the development of plastics industry, the range of application of plastic product constantly expands, and the ratio shared by plastic also rapidly increases。Mould of plastics is a kind of sectional die for extrusion molding, injection, compression moulding, blowing and low ratio foamed molding, and it mainly includes upper die and lower die, and generally upper mould is provided with core, and counterdie is provided with die cavity。But, injection mold of the prior art, after matched moulds, remains substantial amounts of air between upper and lower mould, the air of residual is easily caused some technological deficiency following: 1, increase the pressure at charging aperture place, make raw material not flow in die cavity uniformly, finally affect the concordance of moulding；2, moulding there is bubble, directly result in the quality problems of moulding；3, the pressure at charging aperture place is relatively big, and the requirement of air compressor machine is higher, and then increases production cost and produce limitation。
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, injection moulding are uniform, it is possible to effectively alleviate charging aperture pressure and also can ensure that the vacuum mold that will not produce bubble in injection-molded work。
This utility model be the technical scheme is that this vacuum mold includes baffle plate, cope match-plate pattern, die, lower bolster and lower mould bottom plate, the die joint of described lower bolster is provided with seal groove, described seal groove arranges around described die joint and is provided with sealing ring in described seal groove, described die joint is additionally provided with at least one aspirating hole, described aspirating hole is connected with the air flue within described lower bolster, described air flue connects with outside vaccum-pumping equipment, the sky of described vacuum mold, side is equipped with seal cover board。
Further, described vacuum mold also includes the ejector retainner plate being arranged between described lower bolster and described lower mould bottom plate and the some thimbles being fixedly installed on described ejector retainner plate, described ejector retainner plate is fixing with the gas column of peripheral cylinder to be connected, some described thimbles run through described lower bolster and described die top pressure injection workpiece, some nitrogen springs it are provided with between described ejector retainner plate and described lower bolster, being provided with seal washer between described ejector retainner plate and described lower mould bottom plate, described seal washer is set on the gas column of peripheral cylinder。
Further, described seal cover board and described vacuum mold sky, be equipped with sealing ring between side。
Further, described seal cover board by the sky of sunk screw and described vacuum mold, side fix and be connected, be provided with sealing ring in the screw hole on described seal cover board。
The beneficial effects of the utility model are: owing to this utility model includes upper baffle plate, cope match-plate pattern, die, lower bolster and lower mould bottom plate, the die joint of described lower bolster is provided with seal groove, described seal groove arranges around described die joint and is provided with sealing ring in described seal groove, described die joint is additionally provided with at least one aspirating hole, described aspirating hole is connected with the air flue within described lower bolster, described air flue connects with outside vaccum-pumping equipment, the sky of described vacuum mold, ground is equipped with seal cover board on side, described vacuum mold also includes the ejector retainner plate being arranged between described lower bolster and described lower mould bottom plate and the some thimbles being fixedly installed on described ejector retainner plate, described ejector retainner plate is fixing with the gas column of peripheral cylinder to be connected, some described thimbles run through described lower bolster and described die top pressure injection workpiece, some nitrogen springs it are provided with between described ejector retainner plate and described lower bolster, it is provided with seal washer between described ejector retainner plate and described lower mould bottom plate, described seal washer is set on the gas column of peripheral cylinder, the sky of described seal cover board and described vacuum mold, ground is equipped with sealing ring between side, described seal cover board is by the sky of sunk screw with described vacuum mold, side, ground is fixing to be connected, it is provided with sealing ring in screw hole on described seal cover board, so the advantage that this utility model has following aspect:
1, by the sealing ring in described seal groove, make to realize between described cope match-plate pattern and described lower bolster fully sealing, make to be formed between described cope match-plate pattern and described lower bolster the state of a perfect vacuum again through described aspirating hole, and then the pressure that effectively solves charging aperture place is excessive and that cause charging uneven with, containing alveolate problem in raw material, it is to avoid moulding is bad。It addition, the pressure reducing charging aperture place also can reduce the requirement to air compressor machine, and then reduce production cost and produce limitation。
2, in the sky of described mould, side increase seal cover board and on the gas column of extraneous cylinder, set up the vacuum environment that seal washer can further ensure that in die cavity, improve quality and the concordance of product。
