Description
Technical field
The present invention relates to a kind of rubber production mould, is a kind of rubber injection sulfurizing mould with cooling channel specifically.
Background technology
At present, the tradition injection sulfurizing mould that uses in the rubber production industry all is comprised of heating plate, cope match-plate pattern and lower bolster, the upper surface of heating plate has total Jiao Dao, a plurality of injection orifices corresponding to position are all arranged on heating plate and the cope match-plate pattern, injection orifice all is connected with total Jiao Dao, be evenly equipped with Jiao Dao and forming cavity between cope match-plate pattern and lower bolster, each injection orifice all is connected with a Jiao Dao at least, and each Jiao Dao all is connected with a forming cavity at least.During use, sizing material after the heating is imported in the total glue of the heating plate road, and through being full of forming cavity behind injection orifice, the Jiao Dao, then heating plate or heating plate and lower bolster are heated simultaneously, the sulfidization molding so that the sizing material in the forming cavity is heated, thus required rubber product formed.In the process of this rubber curing forming, the sizing material that is positioned at the total Jiao Dao of heating plate and heating plate, the cope match-plate pattern injection orifice sulfuration of can being heated simultaneously, and in a single day rubber carry out vulcanizing treatment, just can't again utilize.Therefore, use traditional mould to carry out vulcanization of rubber operation meeting and produce a large amount of rubber scraps, not only increased cost, but also needed labor intensive that these rubber scraps are removed from mould, affected production efficiency.
Summary of the invention
The problem to be solved in the present invention provides a kind of rubber cooling channel injection sulfurizing mould, adopts this mould, can reduce the rubber scrap that sulfidation produces, and reduces cost, enhances productivity.
For addressing the above problem, take following scheme:
Rubber cooling channel injection sulfurizing mould of the present invention comprises lower bolster, cope match-plate pattern and heating plate, and lower bolster, cope match-plate pattern and heating plate are stacked together from bottom to top successively, and heating tube is arranged in the heating plate.Injection orifice is all arranged on described heating plate and the cope match-plate pattern, and both injection orifice quantity and position correspondence.Be evenly equipped with Jiao Dao and forming cavity between the lower surface of described cope match-plate pattern and the upper surface of lower bolster, each group injection orifice all is connected with a Jiao Dao at least, and each Jiao Dao all is connected with a forming cavity at least.Be characterized in that described heating plate top has stacked thermal insulation board, cold plate and panel from bottom to top successively, injection orifice is all arranged on thermal insulation board and the cold plate, the injection orifice of thermal insulation board, cold plate is all corresponding with injection orifice quantity and the position of heating plate, cope match-plate pattern.Total injection orifice is arranged on the described panel, between the lower surface of panel and the upper surface of cold plate total Jiao Dao is arranged, total injection orifice is connected with total Jiao Dao, and total Jiao Dao is communicated with mutually with injection orifice.Be processed with condensation pipe in the described cold plate.
The further improvement of the present invention scheme is to be equipped with an injection-tube in arbitrary one group of injection orifice corresponding to described cold plate, thermal insulation board, heating plate and cope match-plate pattern, be between the injection orifice inwall of injection-tube outer wall and cold plate, cope match-plate pattern and be tightly connected, gapped between the injection orifice inwall of injection-tube outer wall and thermal insulation board, heating plate.The upper open end of described injection-tube is connected with total Jiao Dao, and the lower open end of injection-tube and the Jiao Dao corresponding with the injection orifice at its place are connected.Utilizing this injection-tube can stop sizing material contacts with cold plate, thermal insulation board, heating plate, the direct of cope match-plate pattern, and gapped between the injection orifice inwall of injection-tube outer wall and thermal insulation board, heating plate, can reduce heat transfer like this, thereby further avoid the sulfuration of sizing material in the injection orifice, reduce the generation of rubber scrap.
Further improvement project of the present invention is on the injection-tube outer wall corresponding with the condensation pipe position annular groove to be arranged all, forms runner between annular groove and injection orifice, and this runner is connected with described condensation pipe.Like this, can utilize condensate can further reduce the temperature of sizing material in the injection-tube so that the injection-tube outer wall of cold plate section directly is connected with condensation pipe, avoid rubber vulcanization.
In above-mentioned arbitrary scheme, described panel upper surface is fixed with deflector, and bowl-shape groove is arranged on the deflector, and through hole is arranged at the bottom of bowl-shape groove, and this through hole is connected with total injection orifice on the panel.Thereby can avoid sizing material in the irregular overflow of panel upper surface, reduce sizing material to the pollution of die surface.
Take such scheme, have the following advantages:
Because rubber cooling channel injection sulfurizing mould of the present invention has stacked thermal insulation board successively above its heating plate, cold plate and panel, and total injection orifice is arranged on the panel, total Jiao Dao is arranged on the cold plate, cold plate, have on the thermal insulation board and heating plate, the injection orifice that cope match-plate pattern is corresponding, when using this mould to carry out the rubber injection sulfuration, the sizing material that is positioned at the total Jiao Dao of cold plate and injection orifice is subject to the cooling effect of condensed water, can not vulcanize, sizing material in the thermal insulation board injection orifice also can correspondingly slow down curingprocess rate, in working continuously, sizing material in the thermal insulation board injection orifice, sizing material in the total Jiao Dao of cold plate and the injection orifice all can continue to use, and can not affect product performance.Compare with traditional sulfurizing mould, this mould only produces rubber scrap in heating plate, cope match-plate pattern injection orifice, and has avoided having produced in total glue road rubber scrap, thereby reduced manufacturing cost, and its prune job is relatively simple, can reduce labour's consumption, enhances productivity.
