Abstract
The invention discloses a mould forming product comprising external peripheral edges, and the mould forming product is characterized in that small planar platforms are additionally arranged on the closed angles of the external peripheral edges; and the height of the small planar platform is 0.5mm. The mould forming product provided by the invention is simple in structure, convenient in application and high in efficiency, the small planar platforms are additionally arranged on the closed angles to reduce the lengths and sharpness of the closed angles, the strength of the outer edge of a product produced by an injection plastic forming mould is high, the dimension of the finished product is good, and the quality of the product is improved.
Description
Technical field
The present invention relates to a kind of mould-forming article.
Background technique
The mold cavity surface is heated to the heat distortion temperature of plastics, injected plastic then, in the injection moulding process, the temperature of mould remains unchanged, and the temperature of the back mould that finishes drops to the taking-up product gradually, and next injection treatment starts, and die surface heats rapidly.Die temperature raises and reduces all very fast.
Mainly be to shaping die.Offer even distribution water route in shaping die die and the outward appearance slide block, utilize high-temperature high-pressure steam to be the rapid heating medium, chilled water is the cooling medium; Use air tracheae air pressure again, see through RHCM (high-speed and high-temperature forming technique), in plastics, add glass fibre; Produce the shell with reflecting effect, RHCM can solve product problems such as the insoluble joint line of common moulding, current mark, and equipment switches in the water route in die and sliding field; Heating, cooling die.
Before the injection in die and the slide block in the water route with the high-temperature high-pressure steam rapidly heating moulds to higher temperature (120 spend).
Utilize steam to keep temperature in the injection.
Stop to supply with steam in the water route in intact die of injection and the slide block, blow clean residual aqueous vapor in the water route, change logical chilled water again and carry out the mould fast cooling with air conduit air pressure.
Drop to proper temperature, eject die sinking after the product cooling and get into second circulation.RHCM equipment is equivalent to be exactly one can heat fast, fast cooling die.
The product that uses this technology and die production to come out; As shown in Figure 1, when finished product outward appearance edge was sharp angle, wedge angle was difficult for being shaped; And the moulding subsequent handling can be damaged it; Finished product outer rim strength deficiency, the fragile finished size that causes is bad or overproof, greatly the quality of influence power finished product.
Summary of the invention
Purpose: in order to overcome the deficiency that exists in the existing technology, the present invention provides a kind of and produces outer rim intensity height, the mould-forming article that finished size is good through the injection of plastic shaping die.
Technological scheme: for solving the problems of the technologies described above, the technological scheme that the present invention adopts is: the mould-forming article comprise: outside edge is characterized in that: said outside edge sharp corner is set up the facet platform.
As preferred version, said facet podium level is 0.5mm.
Beneficial effect: mould-forming article provided by the invention, simple in structure, easy to use, efficient is high, sets up the facet platform through sharp corner; The length and the acutance of wedge angle have been reduced; It is high to produce outer rim intensity through the injection of plastic shaping die, and finished size is good, has improved the quality of product.
Description of drawings
Fig. 1 is the prior art constructions schematic representation;
Fig. 2 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done explanation further.
As shown in Figure 2, the mould-forming article comprise: outside edge 1 is characterized in that: said outside edge sharp corner is set up facet platform 2.
As preferred version, said facet platform 2 highly is 0.5mm.
Mould-forming article provided by the invention, simple in structure, easy to use, efficient is high, sets up the facet platform through sharp corner; The length and the acutance of wedge angle have been reduced; It is high to produce outer rim intensity through the injection of plastic shaping die, and finished size is good, has improved the quality of product.
Below disclose the present invention with preferred embodiment, so it is not in order to restriction the present invention, and all employings are equal to replacement or the technological scheme that obtained of equivalent transformation mode, all drop within protection scope of the present invention.
Claims (2)
1. mould-forming article, comprising: outside edge is characterized in that: said outside edge sharp corner is set up the facet platform.
2. mould-forming article according to claim 1 is characterized in that: said facet podium level is 0.5mm.
