Abstract
The invention discloses a location column for a mould, comprising a column body. The location column is characterized in that the column body is configured to be a two-section type sphere or a cross-rib structure convenient to be poured by a plastic mould, and with a small-diameter top and a slightly-large-diameter bottom; a fillet radius R at the junction of the column body and a bottom plate is 1.0 mm; chamfer radiuses C at the two steps of the two-section type sphere are 0.3 mm; the diameter d of the upper-section sphere of the two-section type sphere is not less than 0.2 mm, and the height h of the upper-section sphere is less than 3 mm; and the maximum diameter A of the lower-section sphere is less than 3.5 mm, and the height of the lower-section sphere is greater than 2 mm. The location column for a mould disclosed by the invention is simple in structure and convenient in use; and a flow rate is increased and the strength of the location column is enhanced, which is very important for a whole injection moulding production process, so that the quality of products is improved.
Description
Technical field
The present invention relates to a kind of mold position post.
Background technology
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.Mold temperature raises and reduces all very fast.
Mainly be to mould.Offer even distribution water route in mould die and the outward appearance slide block, utilize high-temperature high-pressure steam to be the Fast 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 duct 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.
Through the product that this mould waters out, as shown in Figure 1, when the reference column that in product, has the meticulous d of too high H, easily lack of fill and fracture situation, thus influence the total quality of product.For this reason, need do an improvement to the reference column of product, relevant mould also adjusts and avoids this situation.
Summary of the invention
Purpose: in order to overcome the deficiency that exists in the prior art, the present invention provides a kind of simple in structure, easy to use, mold position post that efficient is high.
Technical scheme: for solving the problems of the technologies described above; The technical scheme that the present invention adopts is: the mold position post; Comprise: cylinder is characterized in that: said cylinder is set to be convenient to the little following big slightly two-part circle or the cross rib structure of diameter of top diameter of plastic mould pouring.
The radius of corner R of said cylinder and back plate connections is 1.0 mm.
As preferred version, the chamfer radius C at two step places of said two-part circle is 0.3 mm; The diameter d of said two-part circle epimere circle is not less than 1.2 mm, and height h is less than 3 mm; The maximum gauge A of hypomere circle is less than 3.5 mm, and height is greater than 2 mm.
Beneficial effect: mold position post provided by the invention, simple in structure, easy to use, increased the intensity of flow and reference column, extremely important for whole injection moulding production process, improved the quality of product.
Description of drawings
Fig. 1 is the prior art constructions sketch map;
Fig. 2 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done explanation further.
As shown in Figure 2, the mold position post comprises: cylinder 1, cylinder 1 are set to be convenient to the little following big slightly two-part circle or the cross rib structure of diameter of top diameter of plastic mould pouring; Cylinder 1 is 1.0 mm with the radius of corner R of base plate 2 junctions.
As preferred version, the chamfer radius C at two step places of said two-part circle is 0.3 mm, and the diameter d of said two-part circle epimere circle is not less than 1.2 mm, and height h is less than 3 mm; The maximum gauge A of hypomere circle is less than 3.5 mm, and height is greater than 2 mm.
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 technical scheme that obtained of equivalent transformation mode, all drop within protection scope of the present invention.
