Abstract
The utility model relates to an injection molding die for preventing the bottom of a battery connector from being bent. The injection molding die comprises a front die and a rear die which form a die cavity, wherein the die cavity comprises a front die cavity in the front die and a rear die cavity in the rear die; and the shape of the die cavity is matched with the appearance of the battery connector. The injection molding die is characterized in that a reversed gradient plate is embedded into the bottom side of the rear die cavity; and an outwards arched angle of the reversed gradient plate is 0.4 to 0.45 degree. After injection molding is finished, the battery connector has certain temperature and is made of plastic; so, when a thimble jacks a product out, the bottom of the battery connector is easily inwards bent; therefore, the embedded reversed gradient plate can correct the bent bottom; and the quality of the injection-molding jacked product is extremely high.
Description
Technical field:
The utility model relates to a kind of injection mold, relates in particular to a kind of injection mold for the anti-bending in battery connector bottom surface.
Background technology:
As illustrated in Figures 5 and 6, the shape of battery connector 4, this battery connector 4 is to adopt injection machine integrated in production and processing, its injection mold that adopts comprises front mould, rear mold and thimble, the rear portion that is installed in injecting head that front mould and rear mold are vertical, the raw material of melting is injected in the die cavity of front mould and rear mold formation, after injection moulding is finished, by the thimble ejecting product, because what material adopted is plastics, forming injecting products in die cavity when, the bottom surface of battery connector is to the inside bending easily, the product that causes injecting has a lot of defective products generations, causes the waste of material.
Summary of the invention:
The technical problem that the utility model solves provides a kind of injection mold for the anti-bending in battery connector bottom surface, and the quality that ejects after the injection moulding of assurance product produces the phenomenon of inside bending when avoiding the battery connector bottom surface to eject.
The technical scheme in the invention for solving the technical problem is: a kind of injection mold for the anti-bending in battery connector bottom surface, comprise forming front mould and the rear mold of die cavity, described die cavity comprises front die cavity on the front mould and the rear die cavity on the rear mold, should be provided with numerous rear mold mold inserts in the rear die cavity, position by numerous rear mold mold inserts arranges the shape that guarantees this die cavity and the profile of battery connector is complementary, be inlaid with a back draught plate in the bottom side of described rear die cavity, the angle that described back draught plate outwards arches upward is 0.4 °～0.45 °.
Further, the angle that outwards arches upward of described back draught plate is 0.43 °.
The beneficial effect of this device: after injection mo(u)lding, because this moment, also there was certain temperature in battery connector, material own is plastics, so during the thimble ejecting product, be easy to cause the battery connector bottom surface to bend to the inside, like this, corrected by the back draught plate of inlaying, guaranteed that injection moulding ejects being of high quality of rear product.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the top view of the utility model front mould;
Fig. 2 is the top view of the utility model rear mold;
Fig. 3 is the enlarged diagram at A place among Fig. 2;
Fig. 4 is the position view of back draught plate and rear mold mold insert in the utility model;
Fig. 5 is the stereogram of battery connector;
Fig. 6 is the upward view of Fig. 5.
Among the figure: 1, front mould 11, front die cavity 2, rear mold 21, rear die cavity 22, rear mold mold insert 3, back draught plate 4, battery connector.
The specific embodiment:
A kind of injection mold for the anti-bending in battery connector bottom surface shown in Fig. 1-4, comprise forming front mould 1 and the rear mold 2 of die cavity, described die cavity comprises front die cavity 11 on the front mould and the rear die cavity 21 on the rear mold, should be provided with numerous rear mold mold inserts 22 in the rear die cavity 21, position by numerous rear mold mold inserts 22 arranges the shape that guarantees this die cavity and the profile of battery connector 4 is complementary, be inlaid with a back draught plate 3 in the bottom side of described rear die cavity 21, the angle that described back draught plate 3 outwards arches upward is 0.4 °～0.45 °.
Further, the angle that outwards arches upward of described back draught plate 3 is 0.43 °.
After injection mo(u)lding, because this moment, also there was certain temperature in battery connector 3, material own is plastics, so during the thimble ejecting product, be easy to cause battery connector 4 bottom surfaces to bend to the inside, like this, corrected by the back draught plate 3 of inlaying, guaranteed that injection moulding ejects being of high quality of rear product.
It is emphasized that, it more than is better implementation column of the present utility model, be not that the utility model is done any type of restriction in appearance, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
Claims (2)
