Technical field
This utility model is related to be molded production industry technical field, more particularly to a kind of injection mould ingate cut-out structure.
Background technology
Injection mo(u)lding is that thermoplastic cement material is injected in mould in the die cavity with required form, waits plastic material cold But after solidifying, mould is opened by the plastic cement machining object ejection for solidifying, the method to obtain products formed.Due to injection molding forming method tool Have that molding expense is low, short molding cycle, the features such as forming process is simple and is easy to forming shape complicated plastic cement products, therefore Plastic cement products manufacture field is using extremely widespread.Traditional diaphragm gate mould after die sinking, the plastic of injection mo(u)lding in mould Always connect together with the condensate at a cast runner, it is impossible to be automatically separated, and need to cut off plastic and condensate and just can produce Operational product.Way general at present is to increase and go by hand cast gate operation, utilizes and manually plastic is cut from condensate Separate.Above-mentioned operation is needed to arrange for staff and is operated using special equipment, causes high labor intensive, low production efficiency, people Work processing ease makes that the cast gate tangent plane of plastic is irregular, out-of-flatness, and severe patient can also make thin-gage goods deformation occur.Therefore mould The removal of material products cast gate is the Injection Industry technical staff problem to be solved, for this purpose, we have proposed being poured in a kind of injection mould Mouth cuts off structure to solve the above problems.
Utility model content
The purpose of this utility model is, in order to solve shortcoming present in prior art, and to pour in a kind of injection mould for proposing Mouth cut-out structure.
To achieve these goals, this utility model employs following technical scheme:
A kind of injection mould ingate cuts off structure, including upper mould fixed plate, upper bolster and front cavity, the upper mould fixed plate Positioned at the top of upper bolster, the relative side of the upper bolster and upper mould fixed plate is provided with corresponding groove, the upper bolster Die cavity is formed and upper mould fixed plate between, rear cavity is installed in the upper mould fixed plate, shifting block is installed in the rear cavity Unit, the shifting block unit includes slide block and shifting block, and the upper surface of the rear cavity is provided with dragging track, in the dragging track Slide block is provided with, the slide block is provided with shifting block insert port, and the shifting block inserts into the mouth positioned at shifting block, and the side of the rear cavity sets There is draw-in groove, the draw-in groove is engaged with the insertion end of shifting block, and be provided between shifting block and rear cavity and stir cavity, the rear cavity Sliding block and limited post are provided with, the rear cavity is provided with four the second support columns, and the slide block is solid by sliding block Be scheduled in dragging track, the rear cavity is provided with travel switch block, the upper end of the rear cavity is provided with front cavity, it is described before Die is located in the groove of upper bolster lower end, and the upper bolster is provided with dust excluding plate.
Preferably, the rear cavity is arranged at the lower section of front cavity.
Preferably, it is coated with anticorrosive coat on the upper bolster and upper mould fixed plate.
Preferably, the upper mould fixed plate is provided with band beam road beam mouth, the end connection die cavity of the beam mouth and The cast gate in beam road.
In this utility model, after mould filling molding, by the power of injection moulding machine mould open action, slide block is produced by shifting block Raw pull strength slides, and slide block is moved downward so as to play the effect of cut-out cast gate, eliminates follow-up artificial shearing pouring gate work Sequence reduces production cost, reaches automated production requirement so that product cast gate to go out stripping and slicing smooth attractive in appearance, be not required to Increase injection pressure to lose machine, this utility model improves production efficiency by the function of pruning cast gate automatically, saves The waste of raw material, reduces the demand to machine quantity, reduces cost of labor, improves the comfort of product, greatly carries The high practicality of injection mold, with wide market prospect, is adapted to promote.
