Abstract
The utility model discloses a hidden three-plate mold pin-point gate injection mold, comprising a panel, a top clamp plate, a plate A and a plate B which are connected in sequence, wherein a mold core is arranged between the plate A and the plate B; a mold cavity and a slide block corresponding to the mold cavity are arranged inside the mold core; a runner is arranged between the top clamp plate and the plate A. The hidden three-plate mold pin-point gate injection mold also comprises a pin-point gate which is communicated with the runner and passes through the plate A and the mold core; the outlet of the pin-point gate is arranged inside the slide block, and is communicated with the mold cavity by contact of the slide block and the mold cavity. By adopting the hidden three-plate mold pin-point gate injection mold, the outlet of the pin-point gate is moved to the inside of the slide block, plastic cement enters the mold cavity to form the product from one side of the slide block contacting the inner side of the mold cavity, and the residue cement at the pin-point gate and the product are cut open by the slide block in the demolding process. Thus, the residue cement is prevented from being formed on the product appearance, and the product is beautiful in appearance and good in hand feeling.
Description
Technical field
The utility model relates to a kind of injection-moulding device, particularly a kind of hidden three template die spot pouring mouth injection moulds.
Background technology
Three template die spot pouring mouths can be applicable to various forms of goods, near residual stress spot pouring mouth is little, can break voluntarily the mouth of a river, can realize automated production, for larger goods can Multi-spot pouring to reduce deformation of products, but injection pressure loss is large, and majority will adopt three template die structures so that spot pouring mouth can directly enter on product.
General expression three template die spot pouring mouth injection moulds shown in Fig. 1 and 2, its due to spot pouring mouth 17 from the direct hole irrigation of die on product 19 outer surfaces, therefore on product 19, can there be a glue mouth 17 culls 20 (as shown in Figure 3), even have wire drawing phenomenon, thereby bring vision and the defect such as feel is poor to outward appearance.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of hidden three template die spot pouring mouth injection moulds, to avoid forming spot pouring mouth cull in product appearance, guarantees that product appearance is attractive in appearance.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of hidden three template die spot pouring mouth injection moulds, comprise the panel, water gap plate, A plate and the B plate that connect successively, between described A plate and B plate, be provided with die, in described die, there is the slide block of die cavity and corresponding described die cavity, between described water gap plate and A plate, be provided with runner;
Also comprise the spot pouring mouth that is communicated with and passes described A plate and die with described runner, the outlet of described spot pouring mouth is arranged in described slide block, and is communicated to described die cavity by described slide block and die cavity contact side.
Preferably, in described slide block, be provided with breach, the entrance of described breach is communicated to described spot pouring mouth, and outlet is communicated to described die cavity concordant with described die cavity.
Pass through technique scheme, the hidden three template die spot pouring mouth injection moulds that the utility model provides, it is by moving to the outlet of spot pouring mouth in slide block, plastic cement enters die cavity and forms product from contacting a side of die cavity inner side in slide block, and during the demoulding, slide block can cut the cull at spot pouring mouth place and product, thereby avoided forming cull in product appearance, product appearance is beautiful, good hand touch.

The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
With reference to figure 4 and 5, the hidden three template die spot pouring mouth injection moulds that the utility model provides, comprise the panel 11, water gap plate 12, A plate 13 and the B plate 14 that connect successively, between A plate 13 and B plate 14, be provided with die 15, in die 15, there is the slide block 18 of die cavity and corresponding die cavity, between water gap plate 12 and A plate 13, be provided with runner 16; Also comprise the spot pouring mouth 17 that is communicated with runner 16 and passes A plate 13 and die 15, the outlet of spot pouring mouth 17 is arranged in slide block 18, and is communicated to die cavity by slide block 18 and die cavity contact side; Wherein, be provided with breach 21 in slide block 18, the entrance of breach 21 is communicated to spot pouring mouth 17, and outlet is communicated to die cavity concordant with die cavity.
The hidden three template die spot pouring mouth injection moulds that the utility model provides, it is by moving to the outlet of spot pouring mouth 17 in slide block 18, plastic cement enters die cavity from a side of the interior contact die cavity of slide block 18 inner side and forms product 19, and during the demoulding, slide block 18 can cut the cull at spot pouring mouth 17 places 20 and product 19, thereby avoided forming in appearance cull 20 at product 19, as shown in Figure 6, only can leave cull 20 vestiges and not affect outward appearance in the some glue position of product 19 inner sides, product 19 outward appearances be beautiful, good hand touch.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.To the multiple modification of above-described embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
