Abstract
The utility model discloses an injection mold field especially discloses an injection moulding mould in table tennis body heat runner wire dot system, including preceding template, back template, the rear end face of preceding template is provided with the front mould mold insert of the protruding form of a plurality of independent hemisphere, and the preceding terminal surface of back template is provided with a plurality of clamping inserts that are the sunken form of hemisphere, and clamping inserts just mutually supports with front mould mold insert one -to -one, is provided with the hot runner that feeds through in proper order in the preceding template, advances jiao kou, the pin mark advances jiaokou, and the pin mark advances jiaokou and runs through the front mould mold insert. Adopt this kind of structure, injection moulding's table tennis hemispheroid water a little equal shaping at the internal surface of hemispheroid, can not the shaping at spheroidal surface, including adopt the pin mark to advance jiao kou, can exempt spheroid surface secondary operation, solved that present processing table tennis process is loaded down with trivial details, the material extravagant, processing is slow, output is on the low side, the problem higher for the cost.
Description
Technical field
The utility model relates to mould applications, particularly relates to injection forming mold in a kind of table tennis body heat runner pin point formula.
Background technology
Table tennis is time-honored industry, the special plastic sheet material hot pressing machine-shaping of the shaping employing of existing table tennis so far or cold runner pouring basin injection moulding. In 2013.08.28 bulletin, notification number be CN203157037U Chinese utility model patent in, disclose the mould of a kind of disposable production hollow ball shell, when shaping half spherical lower casing, lower mode cavity in mould is the half spherical of concave and downward convex, fluid leads to the top of lower mode cavity by runner by hole for injecting glue, and namely hole for injecting glue is led on lower casing internal surface, even if pouring basin injection molding process cast gate salvage material is imperfect, formed protruding in lower casing, also do not affect the outward appearance of this lower casing; But this practicality is novel when shaping half spherical upper casing, upper cavity in mould is recessed half spherical of epirelief, fluid still leads to the top of upper cavity by runner by hole for injecting glue, owing to pouring basin injection molding process cast gate salvage material is imperfect, the top of the outside surface of the upper casing then formed out has projection, need follow-up secondary processing to remove, cause that operation is loaded down with trivial details, waste of material, processing is slow, output is on the low side, the problem higher relative to cost.
Practical novel content
For overcoming above-mentioned shortcoming, the purpose of this utility model be to provide a kind of operation simple, save material, processing fast, injection forming mold in the table tennis body heat runner pin point formula of output height, advantage of lower cost.
In order to reach above object, the technical solution adopted in the utility model is: injection forming mold in a kind of table tennis body heat runner pin point formula, comprise front template, rear pattern plate, the aft end face of described front template is provided with the front mould edge part of multiple independent hemisphere convex, the front end face of described rear pattern plate is provided with multiple rear mold edge part in hemisphere recess, described rear mold edge part and front mould are inlayed part one_to_one corresponding and cooperatively interact, described front template is provided be connected successively hot runner, glue-feeder, pin point glue-feeder, described pin point glue-feeder run through front mould edge part. in the utility model table tennis body heat runner pin point formula, the useful effect of injection forming mold is that fluid is all from hot runner, glue-feeder, pin point glue-feeder enters in the body formed chamber of hemisphere formed by front mould edge part and rear mold edge part, and inlaying part due to front mould is hemisphere convex, and rear mold edge part is hemisphere recess, and hot runner, glue-feeder, pin point glue-feeder is arranged on front template, then no matter the episphere of shaping table tennis still descends hemisphere, table tennis half spheroid of injection moulding (on, lower hemisphere) water the internal surface being a little all molded over half spheroid, the outside surface of spheroid can not be molded over, so not affect the profile of table tennis half spheroid, without the need to carrying out secondary processing again, in addition, adopt pin point glue-feeder also can exempt spherome surface secondary processing, there is operation then simple, save material, processing is fast, output height, the advantage of advantage of lower cost, solves to water in prior art and is a little molded over half outer surface of spheroid, it is necessary to secondary processing, causes operation loaded down with trivial details then, waste of material, processing is slowly, output is on the low side, the problem higher relative to cost.
It is that multiple described front mould edge part is separate, and dismountable is arranged on the aft end face of front template as further improvement of the utility model. Employing removably connects, once mould edge part damages and can exchange in time before certain, it is not necessary to change a whole set of front template, have cost-saving advantage, to a certain extent, extend the front template life-span.
As further improvement of the utility model it is, in described table tennis body heat runner pin point formula, injection forming mold also comprises front mould push pedal, described front mould push pedal is arranged on the rear of front template, and described front mould edge part stretches out front mould push pedal, is provided with spring between described front template and front mould push pedal. Mould push pedal demoulding before this practical novel employing, during die sinking, spring is with so that front template and front mould push pedal demoulding depart from fast, demoulding is easy.
Preferably, described front template being provided with some guideposts, described some guideposts run through front mould push pedal and the guidepost through hole through rear pattern plate, and described spring is set on the guidepost between front template and front mould push pedal. Guidepost provides the effect of guiding to front mould push pedal, rear pattern plate.
Preferably, described front template is also provided with the shutter of auxiliary demoulding. Shutter is in order to the auxiliary mould demoulding.
It is be provided with vent valve in rear mold edge part described in each as further improvement of the utility model. Make the body formed shrinking percentage of hemisphere comparatively stable.
Preferably, it is provided with copper cover in mould edge part before described in each. Copper cover arrange can isolation cooling system simultaneously water power isolation, in addition, it is also possible to complementary cold and hot flexible.
