Abstract
The utility model provides an injection molding and inner pumping demoulding mechanism for a steering lamp shell. The injection molding and inner pumping demoulding mechanism comprises a male mould, a female mould, sliding blocks and springs, wherein the male mould is provided with a groove which can extend from the edge of the male mould to the central region of the male mould, and the groove is communicated with a mould cavity composed of the female mold and the male mould; the sliding blocks and the springs are arranged in the groove, and the springs are close to the edge of the male mould; and the sliding blocks are pushed and reset by the female mould when the male mould and female mould are compounded, when the female mould and the male mould are separated after injection molding, the sliding blocks can inwards move under the action of the springs, so that the inner pumping type demoulding is finished. Through arranging the sliding blocks, the injection molding and inner pumping demoulding mechanism provided by the utility model can finish the inner pumping demoulding, and the problem that a lamp body is hard to demould is solved.
Description
Technical field
The utility model relates to a kind of mould, relates in particular to a kind ofly to be used for turning in the lamp housing injection moulding of production electric motor car, lamp casing for motorcycle and to take out mould emptier.
Background technology
At present, in the accessory of electric bicycle, motorcycle was produced, a lot of parts such as the lamp housing of light fixture all adopted the injection moulding mode to produce.In process of production, because the installing hole of lamp housing and lamp housing stripping direction are vertical design, and installing hole is darker, causes demoulding difficulty.
Summary of the invention
The purpose of this utility model is to provide a kind of turning in the lamp housing injection moulding to take out mould emptier, to solve the problem of the lamp housing demoulding difficulty that prior art exists.
In order to address the above problem, the utility model provides a kind of turning in the lamp housing injection moulding to take out mould emptier, it comprises punch, die, wherein, also comprise slide block and spring, described punch is provided with the groove that extends to the central area of described punch from the edge of described punch, and described groove is communicated with the die cavity that described die, described punch form, described slide block and spring are located in the described groove, and described spring is near the edge of described punch; Promote, reset when described slide block is subjected to described die during at described punch, described die matched moulds, described die after injection moulding is finished, when described punch separates, finish the inner drawing type demoulding under the effect of described spring thereby described slide block moves inward.
According to the above-mentioned a kind of preferred implementation of taking out mould emptier in the lamp housing injection moulding that turns to, wherein, the cross section of described groove and slide block all is the T type, and described slide block embeds described groove and comes off to prevent described slide block.
By slide block is set, the utility model can be finished the inner drawing type demoulding, thereby solves the problem of lamp housing demoulding difficulty.
Description of drawings
Fig. 1 is the main TV structure schematic diagram of the utility model preferred embodiment;
Fig. 2 is the plan structure schematic diagram of the utility model preferred embodiment.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
Fig. 1-Fig. 2 shows the structure of the utility model preferred embodiment from different perspectives, and as shown in the figure, this preferred embodiment comprises punch 2, die (not shown), slide block 3 and spring 1.At demoulding difficult problem, to compare with the technology of comparing, this preferred embodiment is taken out design in adopting.
Particularly, slide block 3 and spring 1 have been set up.As Fig. 1 (not shown spring 1 among Fig. 1) and shown in Figure 2, punch 2 is provided with the groove (unmarked, as wherein to be provided with slide block 3 and spring 1) that extends to the central area of punch 2 from the edge of punch 2.Groove is communicated with the die cavity that die, punch 2 form, and slide block 3 and spring 1 are located in the groove, and spring 1 is near the edge of punch 2; Promote, reset when slide block 3 is subjected to die during at punch 2, die matched moulds, die, punch 2 separately time injection moulding is finished after, slide block 3 under the effect of spring 1 inwardly (die cavity central area) thus mobilely finish the inner drawing type demoulding.
For anti-limited slip block 3 comes off, as shown in Figure 1, the cross section of groove and slide block 3 all is the T type, can also make more steady that slide block 3 moves like this.
In sum, the utility model can solve the demoulding difficult problem that prior art exists by setting up structures such as slide block, spring.
As known by the technical knowledge, the utility model can be realized by other the embodiment that does not break away from its spiritual essence or essential feature.Therefore, above-mentioned disclosed embodiment with regard to each side, all just illustrates, and is not only.All in the utility model scope or the change that is being equal in the scope of the present utility model all be included in the utility model.
