Abstract
The utility model discloses an injection mould with function of preventing the off center of a thin and long inserts, which comprises an upper mould and a lower mould, wherein both ends of a mould cavity of the lower mould are provided with magnets; both ends of a mould cavity of the upper mould are provided with pressure heads; the lower mould is provided with pressure tanks corresponding to the pressure heads; the shape of the pressure heads and shape of the pressure tanks; the dimension of the pressure heads is slightly smaller than the dimension of the pressure tanks; the shape and the dimension of the mould cavity of the upper mould and the shape and the dimension of the mould cavity of the lower mould are same completely. The injection mould of the utility model is adopted to ensure the positioning of the long and thin inserts and avoid the off center of the long and thin inserts in the process of manufacturing for the inserts.
Description
Technical field:
The utility model belongs to the injection moulding manufacture field, is specifically related to a kind of injection mold of avoiding elongated inserts off-centre.
Background technology:
In the design of product, production process, the performance of plastics can not satisfy the requirements such as intensity, rigidity of product sometimes, just needs to add rigid insert.But for elongated inserts, because the high pressure of injection moulding makes inserts produce flexural deformation easily, like this, the defective of inserts off-centre will appear in product, also can have the concentrated defective of stress simultaneously, influences the quality of product.In addition, during injection moulding inserts occur easily locating bad, mold damage.
The utility model content:
The purpose of this utility model provides a kind of elongated inserts easily location and the injection mold that can avoid elongated inserts off-centre.
The technical solution of the utility model: a kind of injection mold of avoiding elongated inserts off-centre, comprise upper die and lower die, be provided with magnet at the two ends of the die cavity of described counterdie.And the two ends of the die cavity of described patrix are provided with pressure head, and described counterdie this pressure head relatively is provided with indent.Described pressure head and indent shape are complementary, and the pressure head undersized is identical in the cavity shape and the size of the die cavity of the described patrix of indent size and counterdie.
Above-mentioned injection mold, the above indent of counterdie are located at the described magnet outside.
The utility model is used for locating elongated inserts by being provided with magnet by the two ends at the counterdie die cavity, and inserts can not produce displacement; The two ends of last model cavity are provided with pressure head, and the relative pressure head of counterdie place is provided with indent, and in the time of matched moulds, pressure head is pressed into indent with the inserts two ends, make inserts stretch, fix; Inserts places the centre position of upper die and lower die, guarantees that like this inserts after the injection moulding places the shaft position of member fully, can not produce off-centre.
Description of drawings:
Fig. 1 is the utility model mould structure bulk-breaking schematic diagram;
Fig. 2 is a structural formula intention behind the utility model mould matched moulds.
The specific embodiment:
The utility model provides a kind of and is used in the elongated inserts in location, and avoids the injection mold of elongated inserts off-centre in product.
As shown in Figure 1, the utility model is made up of patrix 1 and counterdie 2, wherein, is provided with magnet 3 at the two ends of the die cavity 21 of counterdie 2, holds two points of long and thin metal inserts 4 with magnetic force, to reach the effect of location; The two ends of patrix 1 die cavity are provided with pressure head 12, counterdie 2 relative pressure heads 12 places are provided with indent 22, the form fit of the shape of pressure head 12 and quantity and indent 22, pressure head 12 undersized are in the size of indent 22, and in the time of matched moulds, pressure head 12 is pressed into indent 22 with inserts 4 two ends, make inserts 4 stretch, fix, like this, in the process of injection moulding, inserts 4 can not produce any displacement and flexural deformation; Simultaneously, in the utility model, the cavity dimension and the shape of the die cavity of patrix 1 and counterdie 2 are identical, and inserts 4 places the centre position of patrix 1 and counterdie 2, guarantee that like this inserts 4 after the injection moulding places the shaft position of member fully, can not produce off-centre.
