Summary of the invention
The utility model has overcome above-mentioned shortcoming, and a kind of low-pressure injection molding injection molding is provided, and the technology artisan craftsmanship such as moulds to overcome the existing expensive and loaded down with trivial details pool, has improved product quality and surface aesthetic degree.
To achieve these goals, the utility model is to realize by the following technical solutions:
A kind of low-pressure injection molding injection molding, comprise two gas pawls, described two gas pawls are arranged on the top of low-pressure injection molding injection molding, it also comprises upper die and lower die, constitute injection molding cavity between the upper die and lower die, it is characterized in that also be provided with the adjustment piece between the described upper die and lower die, described adjustment piece has 22.
Described adjustment piece is by grub screw and regulate alignment pin and be fixed on jointly on the patrix, by regulating the distance between described grub screw and the patrix, can determine product wrinkling and bleed whether in injection moulding process.
Adopt the low-pressure injection molding injection molding of said structure, in advance cloth or skin are inserted in the patrix of injection molding cavity, cloth or skin are placed along the upper cavity face, and cloth or skin extend to the counterdie intersection promptly becomes die joint.Such die joint does not need complicated mould design, and die joint is simply regular, and because the envelope material district that cloth or skin form constitutes special die joint, the surface quality of gadget is good, the bonding strength height of cloth or skin and moulding.
Described die joint is made of smooth layer and foaming; Smooth layer is fitted on the part of the lower die of injection molding cavity.Foaming layer is partly dissolved, like this after the injection mo(u)lding, cloth or skin have been bonded on the injection moulded products of plastics, because the high temperature during injection moulding has dissolved the lining of partial foaming layer, form a mixed layer on moulding surface with plastics, so that bonding strength far above original technology.
Now adopt the structural design of low-pressure injection molding injection, the expensive and loaded down with trivial details pool is moulded wait hand process to save, improved product quality and surface aesthetic degree, the while has been improved the production cost and the market competitiveness greatly.
Description of drawings
Fig. 1 is a low-pressure injection molding injection molding cutaway view.
Fig. 2 is the cross section partial sectional view of figure low-pressure injection molding injection molding.
Among the figure: 1 gas pawl, 2 cloth or skin, 3 plastics, 4 adjust piece, 5 patrixes, 6 grub screws, 7 regulating block alignment pins, 8 counterdies, 9 injection molding cavities.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
The cross section partial sectional view that has shown the low-pressure injection molding injection molding of the utility model embodiment with reference to figure 2.As shown in the figure, this low-pressure injection molding injection molding comprises two gas pawls 1, and described two gas pawls 1 are arranged on the top of mould, it also comprises patrix 5 and counterdie 8, constitute injection molding cavity 9 between patrix 5 and the counterdie 8, also be provided with between described patrix 5 and the counterdie 8 and adjust piece 7, described adjustment piece 7 has 22.
Described adjustment piece 7 is by grub screw 6 and regulate alignment pin 7 and be fixed on the patrix 5, by regulating the distance between grub screw 6 and the patrix 5, can determine product wrinkling and bleed whether in injection moulding process.The die joint of common injection mould generally is according to the tangent extension of product surface, because precoat is placed in the upper cavity, precoat stretches along the tiling of upper cavity wall, makes the counterdie 8 and the die joint of patrix 5 change.Precoat tangentially extends along upper cavity, intersect formation envelope material district with counterdie, precoat is placed along upper cavity, and it is outer crossing with patrix 5 tangentially to extend to lower mode cavity, because lining has certain thickness, behind patrix 5 and counterdie 8 matched moulds in the gap at the edge of Injection moulded part less than the thickness of precoat, therefore precoat and patrix when matched moulds clamps, counterdie 8 fits tightly and forms a special die joint, such die joint does not need difficult mould design, as long as the shape according to Injection moulded part presets precoat in die cavity, precoat extends to patrix, the counterdie intersection gets final product.Because tangential face is than the easy processing of normal plane, and many times it is the face of vertical and mould, so easier processing.Such zone face material low-pressure injection molding injection simplicity of design is convenient, and die joint is simply regular, and because the surface quality of so special die joint gadget is good, the bonding strength height of precoat and moulding.
If lining is air-locked materials such as PVC, also need on injection molding cavity, add ventilating area.In order to prevent the gauffer of lining, can place multiple lining pin or air spring isobaris surface device simultaneously in the mould periphery.
