Description
Technical field
The utility model relates to a kind of injection mold, relates in particular to a kind of injection mold with ejecting mechanism in the mould.
Background technology
Injection mold is to use a kind of very widely mould in the present industrial production, mainly form by cover half, dynamic model, ejecting mechanism etc., ejecting mechanism often all is on back mould (being dynamic model) in the present mould, during the mould die sinking, back mould retreats with workbench, the front and back mould separates, and after the back mould retreated into certain position, the ejecting mechanism that the push pedal on the injection machine promotes mould ejected product.
At present, mobile phone products just develops towards frivolous direction, but phone housing also must satisfy the demand of intensity and texture when pursuing frivolous structure.Therefore adopt alloying metals such as magnesium, aluminium, zinc, by the form of die casting, low cost of manufacture, intensity height, the casing part that metal-like is strong have become one of main direction that mobile-phone manufacturers pursue.But the capability of electromagnetic shielding of metal material is good, if phone housing is to be formed by whole covering of metalwork, then can shield mobile phone signal, causes the bad even no signal of mobile phone signal, influences its normal use.Therefore to solve this radio frequency problem, just need to adopt the plastic cement part, be beneficial to mobile phone and have the good signal receiving function in the position of antenna for mobile phone assembling.It is particularly important that the problem of mutually combining of metal parts and plastic cement part seems, the interconnecting in conjunction with mainly finishing by three kinds of forms of metalwork and plastic parts: 1) heat is melted and is connected combination: plastic cement moment hot melt is coated on the metalwork; 2) screw connects combination: with screw fixedly plastic parts and metalwork; 3) in-mould injection connects combination: metalwork (or type spare of other material) is placed in the injection mold, and plastic parts is injected and molded in the mould, metalwork (or type spare of other material) is combined with plastic parts form one.And in-mould injection connects combination, and plastic parts combines with metalwork closely, and junction intensity height, metalwork and plastic parts can be made seamless integral body, and product appearance, performance advantage are obvious.Therefore, the mode of in-mould injection connection combination is used widely.
Be used for the mould that in-mould injection connects combination, generally on cover half, inlay some location mold inserts (shape of its concrete quantity and locating surface is decided according to the shape of metalwork) that are used to locate metalwork, and on the relative forming surface of fixed half and moving half, being formed for the forming cavity of forming plastic cement spare, this forming cavity is partly joined according to the needs that are connected with the metalwork on being positioned at the location mold insert.When carrying out injection mo(u)lding, liquid plastic cement is injected into mold cavity forming, and after the cooling, plastic parts and metalwork are combined closely and be integral.When die sinking, dynamic model retreats, and metalwork breaks away from from the location mold insert, and then, the ejecting mechanism on the dynamic model ejects the combination of plastic parts and metalwork, finishes die sinking.The existing this mould that in-mould injection connects combination that is used for, metalwork can break away from from the location mold insert smoothly in the die sinking process in order to make, leave certain clearance between the locating surface of location mold insert and metalwork, metalwork can produce displacement in matched moulds and injection moulding process like this, cause plastic parts and metalwork mutual dislocation, especially for the high product of required precision, percent defective can be very high.
