Abstract

The utility model discloses a tunnel type glue feeding die structure of a thin-sheet type plastic piece. The die structure comprises a plurality of plastic piece cavities and a runner; a tunnel type sprue is arranged at the bottom of each plastic piece cavity; and the tunnel type sprue is communicated with the runner through a bent runner, so as to form a tunnel type pouring runner. With the adoption of the technical scheme, the tunnel type glue feeding die structure of the thin-sheet type plastic piece provided by the utility model has the advantages of cost conservation, automatic production and the like. Meanwhile, an operator can operate multiple machines.

Description

A kind of sheet plastic tunnel type advances the mould structure of glue
Technical field
The utility model relates to a kind of sheet part cast gate injection structure, and especially a kind of sheet plastic tunnel type advances the mould structure of glue.
Background technology
The sheet part is one of processing parts common in die industry, the product of producing is applied in all trades and professions, and the sheet plastic part is generally used the injection moulding mode and is produced, and product is produced in existing injection moulding, generally the phenomenon that a plurality of products link together along runner be can occur, the operations such as artificial pruning, polishing, the product that just can obtain completing at this moment just needed, operation is loaded down with trivial details, and cost is high and can not realize automated production.
Structure is advanced to water in existing direct side as shown in Figures 1 and 2, and this structure comprises a plurality of plastic die cavities 1 ,And runner 2 ,, described plastic die cavity 1 ,The side is provided with cast gate, this cast gate and feeding-passage 3 ,Be communicated with described runner 2 ,, feeding-passage 3 ,And plastic die cavity 1 ,Be distributed in same plane, this runner 2 ,, feeding-passage 3 ,And plastic die cavity 1 ,Be communicated with successively and form the feed injection runner; In this structure, runner 2 ,, feeding-passage 3 ,And plastic die cavity 1 ,Be distributed in same plane, make complete injection moulding after a plurality of products link together, need manually prune, the operation such as polishing, the product that just can obtain completing, operation is loaded down with trivial details, cost is high and can not realize automated production.
Thus, the inventor considers existing sheet part cast gate injection structure is improved, and this case produces thus.
The utility model content
For the deficiencies in the prior art, the utility model provides a kind of simple and reasonable, convenient to use, production efficiency is higher and cost is low sheet part tunnel gate injection structure.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of sheet plastic tunnel type advances the mould structure of glue, this mould structure comprises a plurality of plastic die cavities and runner, described each plastic cavity bottom is provided with tunnel gate, and described tunnel gate is communicated with formation tunnel type cast runner with runner by curved channel.
Further, the width of described cast gate is in the scope of 0.8mm to 1.5mm.
Further, this tunnel gate injection structure lower end also is furnished with thimble.
compared with prior art, advantage of the present utility model: for showing the phenomenon that a plurality of products link together along runner in prior art, need artificial the pruning, the deficiency of the operations such as polishing, the inventor is provided with tunnel gate at each plastic cavity bottom, described tunnel gate is communicated with formation tunnel type cast runner with runner by curved channel, described runner, curved channel and plastic die cavity are communicated with successively the formation tunnel type and advance the sealing rubber die structure, and the width of cast gate is in the scope of 0.8mm to 1.5mm, make after machining, when utilizing thimble that the product of injection formed is ejected, product itself and feed injection runner connecting portion are in cast gate place's disconnection, saved the operation of artificial pruning, thereby reach cost-effective purpose, this new structure can be realized automated production, realize that a people controls the effect of many machines.

Fig. 1 is the prior art structural representation;
Fig. 2 advances the plastic structure schematic diagram in prior art;
Fig. 3 is the utility model structural representation;
Fig. 4 advances the plastic structure schematic diagram in the utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Embodiment: see also Fig. 3 and shown in Figure 4, a kind of sheet plastic tunnel type advances the mould structure of glue, this tunnel gate injection structure comprises a plurality of plastic die cavities 1 and runner 2, described each plastic die cavity 1 bottom is provided with tunnel gate, and described tunnel gate is communicated with the formation tunnel type by curved channel 3 and pours into a mould runner with runner 2.
Runner 2, curved channel 3 and plastic die cavity 1 are communicated with into successively tunnel type and advance the sealing rubber die structure, and the width of described cast gate is in the scope of 0.8mm to 1.5mm, and this tunnel gate injection structure lower end also is furnished with the thimble (not shown).
the utility model is provided with cast gate in each plastic die cavity 1 bottom, described tunnel gate is communicated with formation tunnel type cast runner by curved channel 3 with runner 2, described runner 2, curved channel 3 and plastic die cavity 1 are communicated with into successively tunnel type and advance the sealing rubber die structure, and the width of cast gate is in the scope of 0.8mm to 1.5mm, make after machining, when utilizing thimble that the product of injection formed is ejected, product itself and runner 2 connecting portions are in tunnel gate place's disconnection, saved the operation of artificial pruning, thereby reach cost-effective purpose, this new structure can be realized automated production, realize that a people controls the effect of many machines.
The above record, only for utilizing the embodiment of this origination techniques content, modification, variation that any those skilled in the art use this creation to do all belong to the scope of the claims that this creation is advocated, and are not limited to those disclosed embodiments.
