Description

A kind of injection mold of sole

Technical field

The utility model is related to injection mold field more particularly to a kind of injection molds of sole.

Background technology

Sole usually requires first to pour into material in injection mold in process of production, obtains a simple formed shoe Mould, later stage are again processed the footwear mould, you can obtain product shoes bottom, sole injection mold therein is a kind of according to sole Shapes and sizes are automatically by the machine of footwear injection molding, and traditional injection mold uses dispensing mouth mode mostly, such mode Glue-feeder can leave a cast gate trace in product surface, and the size of cast gate trace depends on different plastics, often also needs to artificial It goes to wipe out, it is not only time-consuming and laborious, but also easily product is damaged during wiping out, this just needs a kind of do not stay of design to pour The sole injection mold of mouth.

Utility model content

The purpose of this utility model is to provide a kind of injection mold of sole, by setting needle-valve in material head lower end, realizes Small click-through glue mode instead of traditional dispensing mouth mode, after the completion of injection, pulls out needle-valve in die sinking from shaped article Go out, without leaving cast gate trace in product surface, reduce the waste of material, and eliminate the process manually wiped out.

In order to achieve the goal above, the technical solution adopted in the utility model is：A kind of injection mold of sole, it includes The preceding mould and rear mold to cooperate, the rear mold cavity place mold insert, the material of mould before being provided through above the mold insert Head, the material head lower end be connected needle-valve, upper end cooperation thimble, the preceding mould upper end connection stripper plate, the stripper plate Upper end connecting cover plate, cover board middle part offer feed inlet, and the feed inlet is through cover board and extends to preceding mould, described Rear mold lower end connection backing plate, the backing plate lower end connecting bottom board.

Further, counter sink is offered on the cover board, lock screw is provided in the counter sink, it is described Lock screw is through cover board, stripper plate and extends in preceding mould, and the threaded hole with lock screw is offered on the preceding mould.

Further, the preceding mould upper end offers the feed well of connection feed inlet and material head.

Further, it is provided with voltage regulation screw among the stripper plate and preceding mould.

Further, the cooling hole that the preceding mould and rear mold middle part are provided through.

The beneficial effects of the utility model are：

1st, by setting needle-valve in material head lower end, small click-through glue mode is realized, instead of traditional dispensing mouth into glue mode, After the completion of injection, needle-valve from shaped article is extracted in die sinking, without leaving cast gate trace in product surface, reduces material The waste of material, and eliminate the process manually wiped out.

2nd, coordinate thimble in material head upper end, convenient for completing the ejection of stripper plate when needing pressure regulation, in stripper plate and preceding mould Centre setting voltage regulation screw can realize the adjusting of feed pressure, to adapt to different injection raw materials.

The 3rd, perforative cooling hole in the middle part of preceding mould and rear mold is set, can accelerate the cooling of injecting products by conveying coolant Shaping speed improves injection quality and efficiency.
