Compared with prior art, the utility model is being provided with thermal insulation board below the injection pot, intercepted of the influence of the high heat of the high temperature that swaging die produced to sizing material in the material chamber, and the required temperature that reaches of sizing material has the thermal hole of heat-conducting medium to solve by circulation coil-like in the injection pot, not only take away too high heat but also control different temperature by the rubber of different cultivars, guarantee that sizing material remains at the uniform temperature compacted under, not only have good plasticity but also can not cause sulfuration, reach the purpose of the stable performance of improving the quality of products, on the other hand, because the sizing material in the material chamber can carry out repeatedly pressure injection, saved rubber raw materials, realized automated production, entreprise cost is reduced.
Description of drawings
Fig. 1 has provided the utility model sectional structure schematic diagram.
The specific embodiment
Embodiment is described in detail the utility model again below in conjunction with accompanying drawing.
Referring to Fig. 1, rubber injecting device with cold runner is that a kind of rubber compression moulding die or rubber curing forming equipment are in product injection-compression molding process, the sizing material that solves in the material chamber remains uniform temperature, can not vulcanize again to satisfy the existing good plasticity of sizing material, use improve the quality of products performance and save rubber raw materials equipment or mould.
This device comprises fixed upper mould fixed plate 4 and material chamber fixed head 5 on the equipment, material chamber plunger 6 fixes with material chamber fixed head, follow 3 liftings of equipment column and injection pot 7 that fixes and injection pot fixed head 8, be located at the charging of expecting below the plunger of chamber and overlap 20, go up the swaging die 15 of thermal insulation board 9, a plurality of arrangements, reach and the electric hot plate 19 that equipment fixes, following thermal insulation board 18 and head board 17.
The last thermal insulation board 9 of calcium selenate system is located between injection pot 7 and the swaging die 15, certainly, last thermal insulation board preferably is fixed on the cope match-plate pattern of swaging die, can prevent that swaging die from causing a large amount of thermal loss when depanning, cause product to owe sulphur, the effect of last thermal insulation board is to alleviate the influence of the high temperature of swaging die to sizing material in the material chamber.
Swaging die can adopt sandwich construction as required, what present embodiment adopted is three layers of mould, promptly constitute by cope match-plate pattern 10, middle template 11, lower bolster 12, patrix mold insert, middle mould mold insert, fuse etc., adopt multi-mode simultaneously, promptly the sizing material in a material chamber can be repeatedly to multimode die cavity feed, once reinforced in other words can pressure injection multimode product, weighing and reinforced time that single mode is produced have been saved, also avoided the sizing material that once feeds in raw material and wasted when only producing a mould, improve production efficiency of products, reduced product cost.Swaging die 15 is installed in and must guarantees in the equipment to overlap 20 concentrics with charging, is triangular arranged.The patrix of swaging die is inserted and the cope match-plate pattern matched in clearance, and it is spacing on cope match-plate pattern with screw and pad, middle mould is inserted and is cooperated with middle die clearance, and spacing on middle template with screw and pad, fuse and lower bolster matched in clearance, and spacing on lower bolster with jump ring, adopting above method location is in order to make die cavity part energy location-independent, to guarantee the degree of accuracy of each die cavity,, avoided by swaging die through the error that distortion caused that work causes under the HTHP of being everlasting as axiality.Adopt guide pillar, guide pin bushing to locate mutually between the template of upper, middle and lower, and accurately locate formation blank die cavity by bedding-in between each mold insert.
The below of swaging die 15 is the electric hot plate 19 of connection device, following thermal insulation board 18 and head board 17, the jogger hole 13 of full-automatic push rod ejecting mechanism is located in the above-mentioned part, on electric hot plate, be provided with simultaneously a plurality of electric heating pores 16, electrothermal tube is arranged in the hole, realization is heated swaging die, thermocouple in the thermocouple hole 14 connects temperature controller equally, by temperature controller control and mensuration temperature.Electric hot plate and following thermal insulation board can be located at head board above or below, former technology is located at the below, maintains static, the defective that is located at the below is: after head board was released, swaging die lost thermal source, did not just guarantee the necessary temperature of swaging die; Next is that thermal loss is big, has prolonged the product cure time.Now with electric hot plate, down thermal insulation board changes and is located at the top, also is improvements of the present utility model, has overcome the defective that is located at the below.The lower bolster of swaging die is fixed on the electric hot plate, and corresponding navigation system is arranged, and is convenient to quick die change.Head board is positioned on the equipment lower bolster, and lower bolster connection device oil cylinder is realized quick die sinking and high-voltage lock mould.
Dynamic structure of the present utility model is as follows:
The equipment oil cylinder moves downward during die sinking, cope match-plate pattern 10 separates die sinking with last thermal insulation board 9, after die sinking puts in place, head board 17 drives cope match-plate pattern 10, middle template 11, lower bolster 12, electric hot plate 19, thermal insulation board 18 is released towards the working face level together down, after release puts in place, full-automatic push rod liftout attachment rises automatically and once back down cope match-plate pattern and middle template from jogger hole 13, realizes automatic depanning.
After the depanning, when not having enough sizing materials in the injection pot 7, material in the injection pot can be controlled by the travel switch on the column 3, column drives injection pot 7, injection pot fixed head 8, upward thermal insulation board 9 moves downward, injection pot 7 is separated with material chamber plunger 6, and when sizing material was used to a certain degree in the material chamber, column touched travel switch, automatically open injection pot and while equipment alarm, prompting operation worker is reinforced.Lower push rod decline button is pressed in reinforced back, push rod descends, this moment is if product has skeleton, throw in skeleton to swaging die 15 earlier, if it is exoskeletal or thrown in skeleton, then directly close cope match-plate pattern 10 and middle template 11, again by automatic firing switch, head board 17 just drives cope match-plate pattern 10, middle template 11, lower bolster 12, electric hot plate 19, following thermal insulation board 18 pushes towards the equipment level direction, push put in place after, during the supreme thermal insulation board 9 of oil cylinder fast rise, oil cylinder starts high-voltage lock mould function at a slow speed, in the promotion, in, lower bolster, the injection pot fixed head, injection pot is to the plunger 6 directions motion of material chamber, sizing material is exerted pressure, make sizing material annotate die cavity by charging cover 20, injecting glue material amount what by the decision of high-voltage lock mould pressure size, and locked mode pressure can be provided with.
