Detailed description of the invention
Referring to figs. 1 through Fig. 3, the utility model plastics plasticator embodiment is described further.
As shown in Figure 1, 2, a kind of plastics plasticator, this plasticator can extrusion molded plastic chopping board, is put into by polypropylene blank on counterdie 6, forms chopping board by compression moulding.Quick in order to realize upper and lower mould 6 folding, this plasticator structure comprises frame 1, drive motors 2, driving wheel 3, screw mandrel 4, patrix 5 and counterdie 6, and frame 1 is for overall structure that is fixing and support plasticator.Described drive motors 2 to be fixed in frame 1 and to be connected with driving wheel 3 V belt translation, and the casing of drive motors 2 is bolted in frame 1, and a sheathed belt on the driving shaft of drive motors 2, belt is also connected on driving wheel 3.By belt transmission, quick and convenient, structure is simple, easily maintenance and replacing belt.Described screw mandrel 4 is vertically arranged, the low side of described screw mandrel 4 is fixedly connected with patrix 5, the top of described screw mandrel 4 wear penetrate in the center of driving wheel 3 and with driving wheel 3 threaded engagement, described driving wheel 3 drives screw mandrel 4 to move up and down, after drive motors 2 drives driving wheel 3 to rotate, screw mandrel 4 will affect patrix 5 to move.Frame 1 is fixed with four leads 10, described four leads 10 are worn respectively and are penetrated on four angles of patrix 5.Four wire columns that move through of patrix 5 play the effect of leading and balancing, and make patrix 5 stressed more even in motion process, can well keep level, reduce mechanical oscillation to the impact of patrix 5 time patrix 5 moves.
Described counterdie 6 to be arranged at immediately below patrix 5 and to be bolted to connection with frame 1, described frame 1 is provided with nozzle 7, atomizing piece is had in nozzle 7, lubricant can be made can be homodispersely sprayed on counterdie 6 by atomizing piece, described nozzle 7 is just to the die cavity 8 of counterdie 6, and described nozzle 7 is connected with conduit 9, stores lubricant in described conduit 9, described nozzle 7 is provided with switch, and described switch control rule nozzle 7 sprays lubricant on die cavity 8.Switch is hand switch, the switch manually on pressing nozzle 7, nozzle 7 just can be made to spray lubricant, thus reach the effect be convenient in demoulding.And nozzle 7 is prior art, do not repeat them here.
The second embodiment:
As shown in Figure 3, switch is magnetic valve YV, and described magnetic valve YV is connected with control circuit A, and described control circuit A controls the opening and closing of Controlling solenoid valve YV.Realize the control to magnetic valve YV by control circuit A, nozzle 7 is controlled more convenient, concerning very laborsaving the operation of employee, convenient.
Control circuit A comprises limit switch S, power supply VCC, current-limiting resistance R, NPN triode Q and normally closed relay K; Described limit switch S to be fixed on counterdie 6 and closed when upper and lower mould 6 pressing, and described limit switch S one end is connected to power supply VCC, and the other end is coupled to current-limiting resistance R; The other end of described current-limiting resistance R is coupled to the base stage of NPN triode Q; Power supply VCC is met, grounded emitter after the colelctor electrode of described NPN triode Q is coupled to the coil of normally closed relay K; The normally closed electric shock of described relay is connected power supply VCC after connecting with magnetic valve YV.The course of work is: when patrix 5 presses down, and the limit switch S be in below patrix 5 is closed, and the base stage of NPN triode Q is switched on power VCC, the coil of turn-on relay, the normally-closed contact of relay is opened, shut electromagnetic valve YV, thus make nozzle 7 stop spraying lubricant, and when patrix 5 leaves counterdie 6, limit switch S resets, thus makes relay power-off, and the normally-closed contact of relay closes, thus connect for magnetic valve YV, nozzle 7 sprays for counterdie 6.The manual operation of personnel can be effectively reduced, thus raise labour efficiency.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
