Abstract
The utility model discloses a mold positioning column which comprises a column body. The utility model is characterized in that the column body is in a two-section cylinder or cross rib structure of which the upper surface has a smaller diameter than the lower surface, thereby facilitating the pouring of the plastic mold; the fillet radius R of the joint between the column body and the bottom plate is 1.0mm; the chamfer radium C at the two steps of the two-section cylinder is 0.3mm; the diameter d of the upper section of the two-section cylinder is not less than 1.2mm, and the height h is not less than 3mm; and the maximum diameter A of the lower section of the cylinder is less than 3.5mm, and the height is greater than 2mm. The utility model has a simple structure, is convenient to use, and increases the flow rate and the strength of the positioning column, which is very important for the whole injection molding production process, thereby enhancing the product quality.
Description
Technical field
The utility model relates to a kind of mould locating dowel.
Background technology
With the heat distortion temperature of mold cavity surface heating to plastics, injected plastic then, in the injection moulding process, the temperature of mould remains unchanged, and the temperature of complete rear mould 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 for 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 media, chilled water is used air tracheae air pressure again for the cooling media, sees through RHCM(high-speed and high-temperature forming technique), in plastics, add glass fibre, produce the shell with reflecting effect, RHCM can solve the 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.
Use the high-temperature high-pressure steam rapidly heating moulds to higher temperature (120 degree) in injection front cavity and the slide block in the water route.
Utilize steam to keep temperature in the injection.
Stop to supply with steam in the water route in the complete die of injection and the slide block, blow clean residual aqueous vapor in the water route with air duct air pressure, turn again logical chilled water and carry out the mould fast cooling.
Drop to proper temperature, ejection mold-opening enters second circulation after the product cooling.But it is exactly a fast heating that RHCM equipment is equivalent to, fast cooling die.
The product that waters out by this mould, as shown in Figure 1, when the locating dowel that in product, has the meticulous d of too high H, easily lack of fill and fracture situation, thus affect the total quality of product.For this reason, need to do an improvement to the locating dowel of product, relevant mould also adjusts to avoid this situation.
The utility model content
Purpose: in order to overcome the deficiencies in the prior art, the utility model provides a kind of simple in structure, easy to use, mould locating dowel that efficient is high.
Technical scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is: the mould locating dowel, comprise: cylinder is characterized in that: described cylinder is set to be convenient to little following slightly large two-part circle or the cross rib structure of diameter of top diameter of plastic mould pouring.
The radius of corner R of described cylinder and back plate connections is 1.0 mm.
As preferred version, the chamfer radius C at two step places of described two-part circle is 0.3 mm; The diameter d of described 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: the mould locating dowel that the utility model provides, simple in structure, easy to use, increased the intensity of flow and locating dowel, extremely important for whole injection moulding production process, improved the quality of product.
Description of drawings
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 2, the mould locating dowel comprises: cylinder 1, cylinder 1 are set to be convenient to little following slightly large 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 described two-part circle is 0.3 mm, and the diameter d of described 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 utility model with preferred embodiment, so it is not to limit the utility model, and all employings are equal to replaces or technical scheme that the equivalent transformation mode obtains, all drops within the protection domain of the present utility model.
