Abstract
The utility model discloses a resetting device of an injection molding machine, and relates to the field of a manufacturing technology of plastic machineries. The resetting device comprises a de-molding plate arranged between a fixed plate and a movable die plate, wherein a driving cylinder arranged on the fixed plate is connected with the de-molding plate, a push plate is arranged between the movable die plate and a movable die; an ejection pin which is inserted in a movable die guide hole is arranged at one side of the push plate; the push plate is connected with the de-molding plate through an ejection rod; a plurality of threaded holes are formed on the de-molding plate, one end of the ejection rod is provided with a section of threads, and the ejection rod is connected with the de-molding plate by threads. Compared with the prior art, the ejection rod and the de-molding plate are connected by threads, when the die is assembled, a piston rod of the driving cylinder pulls the de-molding plate to move and reset towards the direction of the fixed plate, the de-molding plate drives the ejection rod and the push plate to move and reset all together, the ejection pin moves and resets along with the push plate, therefore the collision phenomenon of the ejection pin and a fixed die is avoided, the ejection pin resets accurately in a balanced manner, the resetting speed is high, and consequently, the production efficiency is high.
Description
Technical field
The utility model relates to plastics machinery manufacturing technology field, especially a kind of resetting means for the injection machine ejecting mechanism.
Background technology
Injection machine is to utilize mould for plastics to make the main former of the plastic products of various shapes thermoplastic or thermosetting material, and wherein the effect of ejecting mechanism is that in type plastic products are ejected to break away from moulds, takes out smoothly product; When the mould matched moulds, ejecting mechanism can be rapidly, reset exactly.The resetting means of existing a kind of injection machine, the resetting means of this injection machine includes the stripper plate be located between fixed head and moving platen, the driving cylinder be contained on described fixed head is connected with described stripper plate, be provided with push pedal between described moving platen and dynamic model, described push pedal one side is provided with thimble and the release link be through in described dynamic model guide hole, described push pedal connects by knock-pin and described stripper plate, described stripper plate is provided with the spacing blind hole of a plurality of described knock-pins, with described dynamic model, is provided with in opposite directions the cover half be contained on solid plate.There is following deficiency in process of production in the resetting means of this injection machine: because knock-pin is inserted in the spacing blind hole of stripper plate, during the mould matched moulds, the piston rod of driving cylinder pulls stripper plate to move and reset towards the fixed head direction, knock-pin separates with stripper plate, when dynamic model and cover half matched moulds during to certain position, cover half and release link connect and promote release link drive push pedal and thimble resets; The phenomenon that the collision of thimble and cover half easily occurs and damage, and thimble resets unevenly, inaccurate, and reset speed is slow, causes production efficiency low.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of balance that resets, accurate, the resetting means of the injection machine that reset speed is fast.
In order to address the above problem, the technical solution adopted in the utility model is: the resetting means of this injection machine, include the stripper plate be located between fixed head and moving platen, the driving cylinder be contained on described fixed head is connected with described stripper plate, be provided with push pedal between described moving platen and dynamic model, described push pedal one side is provided with the thimble be through in described dynamic model guide hole, and described push pedal is connected with described stripper plate by knock-pin.
In the resetting means technical scheme of above-mentioned injection machine, technical scheme can also be more specifically: described stripper plate is provided with a plurality of screwed holes, and an end of described knock-pin is provided with one section screw thread, and described knock-pin is connected with described stripper plate by screw thread.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
Knock-pin and stripper plate are threaded connection, during the mould matched moulds, the piston rod of driving cylinder pulls stripper plate to move and reset towards the fixed head direction, and stripper plate drives knock-pin mobile resetting together with push pedal, thimble moves and resets along with push pedal, avoids occurring the phenomenon of thimble and cover half collision; Reset balance, accurately of thimble, reset speed is fast, and production efficiency is high.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the cutaway view of the A-A place of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:
The resetting means of injection machine includes the stripper plate 2 be arranged between fixed head 1 and moving platen 6 as shown in Figure 1 and Figure 2, fixed head 1 is contained on the workbench of injection machine, the piston rod that is contained in the driving cylinder 4 of fixed head 1 one sides is connected with stripper plate 2 through fixed head 1, and the driving cylinder in the present embodiment is hydraulic cylinder 4; Guide post 3 through fixed head 1 and stripper plate 2 is fixed on moving platen 6 successively, moving platen 6 is connected with dynamic model 10 by mould pin 9, between moving platen 6 and dynamic model 10, push pedal 7 is housed, push pedal 7 one sides are equipped with the thimble 8 be through in dynamic model 10 guide holes, and opposite side is equipped with the knock-pin 5 through moving platen 6; Stripper plate 2 is provided with four screwed holes, and an end of four knock-pins 5 is equipped with one section screw rod, and knock-pin 5 is connected with stripper plate 2 by screw thread; Be provided with in opposite directions with dynamic model 10 cover half 11 be contained on solid plate 12.
During work, after the formed product of injection moulding, open mould, dynamic model 10 is separated with cover half 11, primer fluid cylinder pressure 4, the piston rod of hydraulic cylinder 4 promotes stripper plate 2 and moves towards moving platen 6 directions, stripper plate 2 promotes knock-pin 5 drive push pedals 7 and moves in the same way together, thimble 8 moves and stretches out dynamic model 10 along with push pedal 7, and product is ejected from dynamic model 10, can take out product.When the mould matched moulds, the piston rod of hydraulic cylinder 4 pulls stripper plate 2 to move and reset towards fixed head 1 direction, and stripper plate 2 drives knock-pins 5 and pulls push pedal 7 mobile resetting together, and thimble 8 moves and resets along with push pedal 7, avoids occurring the phenomenon of thimble 8 and cover half 11 collisions; Reset balance, accurately of thimble 8, reset speed is fast, and production efficiency is high.
