The specific embodiment
As shown in Figures 1 to 4, mixed doubles look injection (mo(u)lding) machine described in the utility model mainly is made up of frame 1 and the hydraulic cylinder 2 that shoots material, barrel 3, toning oil path block 4 and the feeding mechanism 5 that are installed on the frame 1.
The hydraulic cylinder 2 that shoots material is the single pole double acting hydraulic cylinder, and its piston rod is affixed with an end face of toning oil path block 4.The opposing end surface of toning oil path block 4 is provided with a single-action hydraulic cylinder 41, and is provided with support 42.Shoot material between the rodless cavity of rodless cavity and single-action hydraulic cylinder 41 of hydraulic cylinder 2 by two pipeline connections in parallel, a pipeline is provided with check valve 21, and another pipeline is provided with direct-acting overflow valve 22.
Be formed with in the barrel 3 to be provided with in the first material bar 33 and the first batch mixing shuttle, 36, the second material pipes 32 in the first material pipe 31 and the second material pipe, 32, the first material pipes 31 and be provided with the second material bar 34 and the second batch mixing shuttle 37.The outlet that one end of barrel 3 is provided with a dual channel list outlet nozzle 35, the first material pipes 31 and the second material pipe 32 is connected with this dual channel list outlet nozzle 35 respectively.The first material bar 33 is connected with the piston rod of single-action hydraulic cylinder 41.The second material bar 34 is affixed with the opposing end surface of regulating oil path block 4.
The course of work of the present utility model is as follows:
1, finishes the fallback procedures that shoots material: the first direction valve of the hydraulic cylinder that shoots material is got, system pressure oil arrives the rod chamber of the hydraulic cylinder that shoots material through the P of first direction valve mouth-B mouth, the piston rod of the hydraulic cylinder that shoots material is retreated, shooting material withdraws the membership behind the piston rod of hydraulic cylinder drives toning oil path block, the first material bar, the second material bar and amount material slide plate and retreats, when retreating, the rodless cavity of hydraulic cylinder of shooting material can form certain back pressure, its back pressure can arrive the rodless cavity of single-action hydraulic cylinder by check valve, thereby makes piston rod release single-action hydraulic cylinder.Also have, the early stage that is retreating, the toning oil path block not amount of drive material slide plate retreats, behind the first material bar and the second material bar slow astern set a distance, first feeding mouth and second feeding mouth respectively with the first pan feeding passage and the second pan feeding channel connection, make the colorant that accumulates in the pan feeding passage be entered the first material pipe and the second material pipe; When the toning oil path block retreated into the stop nut generation conflict that makes support and slide plate back end of tie rod, retreating of oil path block of toning retreated drive amount material slide plate.The first material bar and the second material bar retreat when putting in place, fallback procedures finishes, this moment first, the amount hopper hole and the second amount hopper hole were communicated with first material guide hole and second material guide hole on the cover plate respectively, and the colorant in this moment first material chamber and the second material chamber can inject the first amount hopper hole and second respectively and measure the hopper hole.
2, the injection moulding process that shoots material: the second direction valve of the hydraulic cylinder that shoots material is got, system pressure oil arrives the rodless cavity of the hydraulic cylinder that shoots material through the P of second direction valve mouth-A mouth, the shoot material piston rod of hydraulic cylinder of promotion advances, the piston rod of hydraulic cylinder of shooting material advances and can promote toning oil path block, amount material slide plate, the first material bar, the second material bar and advance to the interior colorant of barrel down, simultaneously, the shoot material pressure of rodless cavity of hydraulic cylinder can be communicated to the rodless cavity of single-action hydraulic cylinder by check valve.In the section just that shoots material, the toning oil path block not amount of drive material slide plate advances, after the toning oil path block advances to certain distance, when the stop nut of its support and slide plate pull bar front end takes place to conflict, advancing of oil path block of toning advances drive amount material slide plate, make the first amount hopper hole and second amount hopper hole and the first pan feeding passage and the second pan feeding channel connection, the colorant that accumulates in the first amount hopper hole and the second amount hopper hole can enter respectively in the first material pipe and the second material pipe, be able to further pan feeding, when the first material bar and the second material bar advance to sealing first feeding mouth and second feeding mouth, go into material process and promptly finish.In the section just that shoots material, because the resistance in the first material pipe is little, pressure is also little, so the forward travel distance of the first material bar and the second material bar is identical substantially; But, arrive when forming pressure in the die cavity with colouring matter, pressure in the first material pipe can sharply rise, when formed pressure in the first material pipe during greater than the Rodless cylinder chamber formed pressure of single-action hydraulic cylinder, thereby the first material bar will halt even retreat the first material pipe is no longer shot material, and the second material bar still can move on and shoot material, thereby reaches the fade effect of double-colored material.
By regulating direct-acting overflow valve, can regulate the interior pressure of rodless cavity of single-action hydraulic cylinder.According to the size of regulating direct-acting overflow valve pressure, can control the first material bar at the forward travel distance of injection moulding process that shoots material.
By regulated quantity material screw rod, but the position of regulated quantity material piece in amount hopper hole, the volume in change amount hopper hole, and then the feeding in adjusting injection rate hopper hole.
By the distance between two stop nuts on the adjusting slider pull bar, the stroke of controllable amounts material slide plate that is: increases distance between two stop nuts, and then the stroke of amount material slide plate shortens; Shorten the distance between two stop nuts, then the stroke of amount material slide plate increases.
The above-mentioned first batch mixing shuttle and the first batch mixing shuttle can make colorant be able to enter mould again after the plasticizing evenly earlier in the injection moulding process that shoots material.
Above-mentioned direct-acting overflow valve also can substitute with the back pressure check valve that can regulate back pressure.
Present embodiment only is a preferred embodiment of the present utility model in sum; unintelligible is qualification to the utility model protection domain; for adjustment that does not exceed technical solutions of the utility model and the change that the technical work personnel in this field are done according to the utility model present embodiment, should think and drop in the protection domain of the present utility model.
