Abstract
The utility model discloses a mould for producing a plastic product with a bracket by the blow-molding process. The mould comprises a left mould and a right mould, wherein the two moulds are enclosed into a die cavity; the inner side wall of the left mould is provided with a concave hole; the shape of the inner surface of the concave hole is matched with that of the outer surface of the bracket arranged in the concave hole; the bracket and the plastic product are connected in the mould after the mould is used for production, therefore, the problems of cooling deformation and relocation do not exist; the precision of the bracket position of the produced plastic product is high; in addition, as the welding process is eliminated, the processing course of parts are shortened and simplified; no welding process is needed, therefore, the production cost is lowered greatly.
Description
Technical field
The utility model relates to a kind of mould that has the support plastic products that is used to produce, and relates in particular to a kind of mould that is used for having by blow molding process production the support plastic products.
Background technology
Current, the plastic products that have support by blow molding process production, blowing goes out plastic products, support respectively earlier, with plastic products, support welding fabrication, carry out outward then, have certain deformation after the cooling owing to be welded on mould, and part needs location once more, the backing positions precision is reduced, and welding needs specialized apparatus in addition, and production cost is higher.
The utility model content
The utility model is at deficiency of the prior art, a kind of mould that is used for having by blow molding process production the support plastic products is provided, after this mould was used for producing, being connected in the mould of support and plastic products carried out, and do not have cooling strain, and orientation problem once more, the plastic products backing positions precision height of producing owing to cancel welding sequence, has shortened and has simplified the process of part in addition, no longer need the operation of welding, production cost can reduce significantly.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of mould that is used for having the support plastic products by blow molding process production, comprise left and right mould, described left and right mould surrounds a die cavity, the madial wall of described left mould is provided with shrinkage pool, the inner surface configuration of described shrinkage pool is suitable with the rack outer surface shape of inserting in the shrinkage pool, this mould has been cancelled welding sequence after being used for producing.
Beneficial effect: the utility model compared with prior art has following beneficial effect:
1) use the utility model to be used to produce the plastic products that have support, being connected in the mould of support and plastic products carried out, there is not cooling strain, and the problem of locating once more, the plastic products backing positions precision height of producing owing to cancel welding sequence, has shortened and has simplified the process of part in addition, no longer need the operation of welding, production cost can reduce significantly.
2) owing to cancelled welding sequence, also promptly can reduce the input of welding equipment, personnel, production station, further reduce cost.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
See Fig. 1～Fig. 4, be used to produce have the support plastic products mould mainly by left and right mould 1,1 ', and the shrinkage pool 2 that is arranged on left mould 1 madial wall constitutes.
Described left and right mould 1,1 ' surrounds a die cavity 4, the inner surface configuration of die cavity 4 and the external surface shape of plastic products to be processed are suitable, the madial wall of described left mould 1 is provided with a shrinkage pool 2, in order to placing rack 3, the inner surface of described shrinkage pool 2 is suitable with support 3 external surface shape of inserting in this shrinkage pool 2.
When having the plastic products of support by blow molding process production, see Fig. 2～Fig. 4, support 3 is put into shrinkage pool 2, the upper surface of the base of support 3 is provided with a step, make the upper surface of base and the sidewall of mould that one gap be arranged, carry out article of manufacture by blowing worker technology then, owing on the sidewall of the upper surface of base and mould a gap is arranged, material enters this gap, and support 3 is covered by on the plastic products body.
