Description
Technical field
The utility model relates to a kind of appearance for household electrical appliance plastic casing without glue-feeder injection mold, belongs to injection mold technical field.
Background technology
Improving constantly along with people's living standard at present, also more and more extensive to application in domestic appliances, but it is also more and more higher that the thing followed requires, if the electric appliance casing of conventional plastic production is sometimes because processing discomfort, product stays cast vestige (being mainly reflected in the vestige that appearance after moulding has mould-injection mouth), thus affect attractive in appearance, the people of being attractive in appearance are used for evaluating one of condition of product to product, if unsightly the sales volume of its product can reduce greatly, vestige removal will will be poured into a mould by various different means to eliminate these defects by factory for this reason, waste time and energy.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of appearance for household electrical appliance plastic casing without glue-feeder injection mold, its structure is simple, appearance can't see the vestige of any mould-injection mouth after moulding, make the appearance looks elegant of household electrical appliance plastic casing, commercially sales volume is very competitive, time saving and energy saving during production.
Appearance for household electrical appliance plastic casing described in the utility model is without glue-feeder injection mold, comprise the dynamic model and quiet mould that cooperatively interact, an injection molding cavity for the injection moulding of household electrical appliance plastic casing is constituted between dynamic model and quiet mould, it is characterized in that: the lower surface of injection molding cavity is the outer surface of household electrical appliance plastic casing, its upper surface is the inner surface of household electrical appliance plastic casing, dynamic model in the middle part of the inner surface of injection molding cavity offers injection channel, the feed end of injection channel is funnel shaped, injection channel discharge end is provided with up big and down small cone body structure.
The conveniently cleaning of an injection mo(u)lding mould-injection mouth, the diameter of preferred described cone body structure lower surface is 3mm ~ 5mm.
In order to injection moulding effect, prevent variations in temperature when injection moulding in injection channel large, preferably described from funnel shaped to cone body structure between the diameter of injection channel be 10mm ~ 15mm.
With above-mentioned reason, preferred described injection channel entire length is from top to bottom 20mm ~ 30mm.
Conveniently clear up an injection mo(u)lding mould-injection mouth (tapering of cone body structure its removal power used when removing different will difference, can according to Force principle) further, the tapering of preferred described cone body structure is 20 degree ~ 30 degree.
Compared with prior art, the utility model has following beneficial effect:
By the appearance for household electrical appliance plastic casing described in the utility model without glue-feeder injection mold, its structure is simple, appearance can't see the vestige of any mould-injection mouth after moulding, make the appearance looks elegant of household electrical appliance plastic casing, commercially sales volume is very competitive, time saving and energy saving during production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structure for amplifying schematic diagram at A place in Fig. 1;
In figure: 1, injection molding cavity 2, injection channel 3, dynamic model 4, quiet mould 5, cone body structure.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
Below by way of specific embodiment, the utility model is described in further detail; but not in order to limit the utility model; all within the present invention's spirit and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
