Description
Technical field
The utility model relates to a kind of IML technique PET film forming mould, is specifically related to a kind of modified form high-pressure molding mould.
Background technology
Traditional high-pressure molding mould is as Fig. 1-2: comprise front cavity, high-pressure gas circuit, pilot pin and rear cavity, pilot pin fixing parts of sheet material during as die mould.But because of pilot pin fixedly the marginal portion of sheet material, the main part of sheet material is not located insert structure, make for the figuratum product of product or edge that has high-quality requirement, traditional high-pressure molding mould can cause distortion, the distortion of pattern form, causes fraction defective high; And the docking structure of conventional high-tension mould front cavity and rear cavity makes the product 5.1 of conventional high-tension mould have the stretched edge of need portion 10, need drawn products to make it meet demand, caused the waste of material and the decline of product quality.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of modified form high-pressure molding mould, and it has overcome conventional high-tension mould and has easily caused pattern form distortion, the low shortcoming with wasting material of product quality.
For addressing the above problem, the technical scheme that the utility model adopts is as follows:
As shown in Fig. 2-Fig. 4, a kind of modified form high-pressure molding mould, it comprises front cavity and rear cavity, and the die cavity that is positioned at front cavity and rear cavity junction; Rear cavity comprises the mould heart that is positioned at die cavity; Matched moulds portion before having in front cavity, matched moulds portion after having in rear cavity, front matched moulds portion and rear matched moulds portion form land area when matched moulds, and die cavity periphery seal is got up; In front cavity, be provided with high-pressure gas circuit; In described front cavity, be also provided with spring lock block device, spring lock block device comprises the first spring and briquetting; Wherein the first spring is fixed in front cavity, and briquetting is fixed under the first spring and stretches into die cavity; Rear matched moulds portion comprises at least two elastic devices, and elastic device comprises the second spring being fixed in rear cavity and be arranged on the mobile on the second spring, and mobile and front matched moulds portion form land area when matched moulds; In mobile, be equipped with pilot pin.
Preferably, for connecting the first spring of described briquetting, it is two.
Preferably, a pilot pin is at least set in described mobile.
Preferably, described in when die opening state, the bottom surface of briquetting is concordant with the bottom surface of described front matched moulds portion.
Preferably, described in when die opening state, the end face of mobile is concordant with the end face of the described mould heart.
The beneficial effects of the utility model are: the spring lock block device in front cavity and the elastic device of rear cavity are fixed the main part of sheet material when pressing mold, make this kind of high-pressure molding mould be difficult for causing pattern form distortion, have reduced the fraction defective of product; The structure that the front cavity of this high-pressure molding mould is docked with rear cavity makes the suit the requirements shape of product of die cavity, sheet material one-shot forming while making pressing mold, without stretched edge portion, has saved material, avoid the decline of product quality in drawing process, promoted product quality.
