Abstract
The utility model relates to a kind of injection mold preparing plastic-metal product, this mould only need add overflowing well at the position easily producing weld mark on the basis of original mould, make due to injection moulding stream liquidate produce weld mark come together in overflowing well, after injection moulding completes, Injection moulded part overflowing well position is wiped out, can effectively reduce and even eliminate weld bond.Adopt plastic-metal product not only appearance looks elegant prepared by the utility model injection mold, technology stability is high, and environmental protection, will progressively replace conventional spray paint technique.
Description
Technical field
The utility model relates to a kind of injection mold, particularly a kind of injection mold preparing plastic-metal product.
Background technology
Plastic-metal is a kind of advanced composite material (ACM), take plastics as matrix, as PP, ABS, PMMA, ABS/PMMA, PC, PC/ABS, ASA, polyester, PS etc., by special design and formula, its final products are made not only to keep the intrinsic characteristic of macromolecule itself, as: low cost, be easy to machine-shaping, high performance, multifunction etc., and outward appearance has typical metal texture and gloss, even if outside surface is subject to brokenly, the outward appearance of internal layer is still consistent in top layer, and forms obvious flaw unlike spraying coating process goods.The appearance of environment-friendly type plastic metal, by progressively substituting traditional spraying coating process, forms huge development space.
Due in plastic-metal formula itself, the auxiliary agent such as metallic pigments, mica titanium nacreous material can be added, the surface of the plastic-metal product that injection moulding is formed, particularly to meet place at melt material flow, form weld mark, largely reduce the attractive in appearance of article surface, the problem of weld bond be also plastic-metal relative to conventional spray paint technique major defect, limit the application of plastic-metal at Injection Industry especially panel product.
Summary of the invention
The purpose of this utility model is exactly to overcome the very easily generation weld bond of above-mentioned plastic-metal in Shooting Technique, affecting product aesthetic problem, propose a kind of injection mold improving plastic-metal product weld mark.
The utility model is achieved through the following technical solutions:
Establish mold cavity and overflowing well in injection mold of the present utility model, described overflowing well is arranged at the position of meeting of mold cavity stream.Come together in by weld mark in overflowing well, the later stage, by cutting out overflowing well, can realize the object improving and eliminate weld mark.Overflowing well offers position, mainly concentrates on melt material flow in mould and to meet welding, easily produces the position of weld mark.The shape of overflowing well can be square, circular or triangle.
Compared with prior art, the injection mold tool that the utility model proposes has the following advantages:
(1) improve and even eliminate the problem that plastic-metal easily produces weld bond in injection moulding process, while cutting down finished cost, reach the object of environmental protection, ensure the surface aesthetics of plastic-metal product simultaneously.
(2) high relative to conventional spray paint technique defect rate problem, adopts plastic-metal Shooting Technique can ensure the stability of producing, has higher accepted product percentage.

Fig. 1 is frame type switch panel decoration mould schematic diagram.
Fig. 2 is two frame-type switch panel decoration mould schematic diagrames.
Fig. 3 is wheel trim mould schematic diagram.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in detail.
Embodiment 1
Existing switch panel decoration, is generally frame type on the market, and adopt plastic-metal injection moulding straight forming, easily produce weld bond, affect product attractive in appearance, can increase overflowing well on mould, mould structure is shown in Fig. 1.After adopting the plastic-metal injection moulding of PP material to complete, product weld mark obviously alleviates.
Embodiment 2
Switch panel decoration another kind is two frame-type on the market, and adopt 2 Shooting Techniques entering glue, lower frame easily produces two weld bonds, can add overflowing well, mould structure Fig. 2 at two places.After adopting the plastic-metal injection moulding of PC/ABS alloy material to complete, wipe out overflowing well 1 overflowing well 2, the basic weldless trace of article surface.
Embodiment 3
Wheel trim is generally circle, and single-point enters glue and easily produces obvious weld bond, and overflowing well is added at the position easily producing weld bond at injection mold, and mould structure is shown in Fig. 3.After adopting the plastic-metal injection moulding of ABS material to complete, weld bond is eliminated substantially.
Table 1 adds and does not add overflowing well weld mark display degree
Note: ★ more multilist shows that weld mark is more obvious, represents do not see weld mark without ★.
From above embodiment 1 ~ 3, by optimal design of the present utility model, the weld mark problem that plastic-metal produces in Injection moulded part can be improved very well.
Scope of the present utility model is not by the restriction of described specific embodiments, and a described embodiment wish is as the single example of illustrating the utility model various aspects.In fact, except content as herein described, those skilled in the art can easily grasp multiple improvement of the present utility model with reference to description above and accompanying drawing.Described improvement also falls within the scope of appended claims.
Claims (3)
1. prepare an injection mold for plastic-metal product, it is characterized in that: establish mold cavity and overflowing well in described injection mold, described overflowing well is arranged at the position of meeting of mold cavity stream.
2. the injection mold preparing plastic-metal product according to claim 1, is characterized in that: described overflowing well is square, circular or triangle.
3. the injection mold preparing plastic-metal product according to claim 1, is characterized in that: described mold cavity is switch panel mould, wheel trim mould.
