Background technology
Injection mold is plastic injection moulding process tooling device used, and it is mainly used in molded thermoplastic plastic products.Injection mold is comprised of moving platen and solid plate two large divisions; moving platen is arranged on the moving platen plate of injector; solid plate is arranged on the solid plate plate of injector; moving before injection, solid plate closure under injector drives, form die cavity and running gate system, and injector is all that plastic melt injects die cavity by running gate system by plastifying; after cooled and solidified; moving, solid plate is opened, and mould emptier is released plastic cement, completes the injection moulding action of a workpiece.
The running gate system of injection mold be plastic cement molten mass from the nozzle of injector out, arrive the passage of flowing through before die cavity in mould, wherein, cast gate is the important structure in running gate system, the form of cast gate is a lot, but no matter adopt the mould gate of what form, its position of offering is of great impact to the forming property of plastic and Forming Quality.Mould gate should be opened in plastic section thickness.When the wall thickness of plastic differs larger, if mould gate is opened in to the thin place of wall, this is that plastic melt enters after die cavity, and not only flow resistance is large, but also easily cooling, affects the mobile distance of melt, and difficulty or ease guarantee to be filled with whole die cavity.The moulding of having relatively high expectations for some surface quality, Workpiece shaping is very high for the requirement of cast gate, often adopt spot pouring mouth to pour into a mould, and spot pouring mouth flow resistance is large in prior art, and envelope is solidifying fast, easily causes plastic melt premature solidification to affect the moulding of product.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of plastic parts moulding quality good, the running gate system of the injection mold of cast gate good concealment.
The purpose of this utility model can realize by following technical proposal: a kind of running gate system of injection mold, comprise top clamping plate, solid plate, core, die cavity, in described solid plate, be provided with sprue bush, described top clamping plate is provided with the locating ring for casting positioning muzzle, it is characterized in that, the discharging opening of described sprue bush stretches between the core and die cavity of mould, the die joint place of described core and die cavity forms the cold slug well of arc, described core is provided with the runner of dive, described runner one side communicates with cold slug well, opposite side flows in die cavity by the deflector of the setting on core.
In the running gate system of above-mentioned injection mold, described deflector comprises the push rod of mould, on described core, offer jogger hole, described push rod upper end offers the portion of stepping down, between the described portion that steps down and core, form diversion cavity, described diversion cavity one end communicates with runner, and the other end communicates with die cavity.
In the running gate system of above-mentioned injection mold, described cold slug well is curved, and described runner entrance is positioned at the middle part of cold slug well.
In the running gate system of above-mentioned injection mold, described die cavity is mould two chambeies, and described cold slug well and runner are two and be centrosymmetric and be arranged in the both sides of sprue bush.
In the running gate system of above-mentioned injection mold, described runner is taper, and described runner end is spot pouring mouth.
Compared with prior art, the running gate system of this injection mold, adopt submarine spot pouring mouth, workpiece gate location is hidden in to the invisible position of use state, do not affect the outward appearance of plastic cement, it is separated that shearing force while utilizing die sinking is carried out the solidifying material of plastic and running gate system, the operation while simplifying the workpiece demoulding; Cold slug well is set in die cavity, stores the condensation stub bar of injection moulding interim nozzle generation and forward's cold burden of melt flows, to prevent that these cold burdens from entering die cavity, affect the speed of melt filling, and the quality of moulding plastic.
