Abstract
The invention discloses a temperature adjustment device for a mandrel in one-step-method injection-blow moulding equipment. The temperature adjustment device is characterized by comprising a mandrel installation seat, a mandrel press plate, a mandrel body, a mandrel head, a water tube and a water tube installation seat, wherein the water tube installation seat is fixed in one head of the mandrel installation seat; the water tube is welded together with the water tube installation seat; the mandrel body and the mandrel installation seat are fixed via the mandrel press plate; the mandrel head is connected with the mandrel body; the mandrel installation seat is provided with an oil inlet and an oil outlet; oil flows in from the oil inlet, enters in the mandrel head via the water tube, and finally flows out from the oil outlet; a first heat-resistant O-shaped ring is installed between the mandrel installation seat and the mandrel head; and a second heat-resistant O-shaped ring is installed between the water tube installation seat and the mandrel installation seat.
Description
Technical field
The present invention relates to the one-step injection blower former, particularly relate to the register of plug in the one-step injection blower former, belong to the plastics machinery field.
Background technology
The equipment of one-step injection blower processing hollow plastic container (for example medicine), its forming process is: plastic raw materials adds the injection moulding hopper behind plasticizing assembly fusing homogeneous, injects die cavity, directly is blow molded into bottle.The core component of one-step injection blow molding is a triangular turntable, and by 120 ° of calibration rotations, plug is installed in the end face of rotating disk, and parison just forms at plug, at last by the moulding of air inflation.Triangular turntable divides three stations, and wherein station one: be the parison station, the plasticizing melt is injected the parison die cavity under low injection pressure, form parison at plug, at this station, bottle neck is precise forming, through after the suitable control, mould is opened, and plug forwards next station to together with parison.Station two: blowing is finished at this station, and mold cavity will determine shape and the outward appearance of bottle, and parison is by from plug air inflation out, when plastics blown be adjacent to the cold wall of mould after, just last moulding of bottle, then, mould is opened, and plug forwards next station to together with bottle.Station three: finish the demoulding at this station, then just enter by conveyer belt that streamline is packed or canned.Injection, blowing, the demoulding three actions are carried out on a machine continuously, and are energy-efficient.Very large in the temperature difference at die parting line place and non-die parting line place through the parison of injection mo(u)lding, cause the goods of blow molding very large in the dimensional discrepancy at die parting line place and non-die parting line place, be difficult to satisfy the client to the requirement on the goods precision.So this difficult problem of the temperature difference that how to solve between mould die parting line place and the overstepping one's bounds mould place is the key of success or failure in the process technology.Prior art is to pass into Compressed Gas to plug to reach the mode of regulating the plug temperature.This mode is very limited to the thermoregulatory effect of plug, is to be difficult to gas temperature is monitored on the one hand, and the heat transmission effect of gas is poor on the other hand.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art existence, a kind of fluid that passes into uniform temperature to plug is provided, directly plug is heated or cool off, thereby indirectly the parison that is attached on the plug is carried out temperature adjustment, regulate the register of plug in the one-step injection blower former of the temperature difference at die parting line place and non-die parting line place.
The technical scheme of the register of plug is in the one-step injection blower former of the present invention: it is characterized in that: comprise the plug mount pad, the plug pressing plate, mandrel body, core head, water pipe and socket for installation of water tube, described socket for installation of water tube is fixed among of plug mount pad, described water pipe and socket for installation of water tube are through welding together, described mandrel body fixes by plug pressing plate and plug mount pad, described core head is connected with mandrel body, described plug mount pad is shaped with fuel feed hole and oil outlet, fluid flows into from fuel feed hole, the water pipe of flowing through again enters core head, flow out from oil outlet at last, the first heat-resisting O type circle is installed between plug mount pad and core head, the second heat-resisting O type circle is installed between socket for installation of water tube and plug mount pad.
The invention discloses a kind of register that relates to plug in the one-step injection blower former, formed by institutes such as socket for installation of water tube, plug mount pad, plug pressing plate, mandrel body, core head and water pipes, during work, the fluid of uniform temperature is inputted the plug mount pad from fuel feed hole, and in the oil-in inflow water pipe (also can be described as oil pipe) of water pipe, from out flow through afterwards runner between water pipe and the core head of oil pipe, the temperature of plug is regulated and control, then from oil-out and oil outlet oil return.The plug temperature control is regulated Main Function after injection moulding is finished, before blowing begins, because the temperature difference of parison at this moment at die parting line place and non-die parting line place directly has influence on the effect of blowing, temperature by the rising plug, come parison is heated again, dwindle parison in the temperature difference at die parting line place and non-die parting line place, reach the required temperature conditions of blowing.The technical program adopts be fluid as temperature control medium, can react to the temperature of plug rapidly, the temperature adjustment precision reaches ± 2 °.
Description of drawings
Fig. 1 is the structural representation of the register of plug in the one-step injection blower former.
The specific embodiment
The present invention relates to the register of plug in the one-step injection blower former, as shown in Figure 1, it is characterized in that: comprise plug mount pad 2, plug pressing plate 3, mandrel body 4, core head 5, water pipe 6 and socket for installation of water tube 1, described socket for installation of water tube 1 is fixed among of plug mount pad 2, described water pipe 6 and socket for installation of water tube 1 are through welding together, described mandrel body 4 fixes by plug pressing plate 3 and plug mount pad 2, described core head 5 is connected with mandrel body 4, described plug mount pad 2 is shaped with fuel feed hole 21 and oil outlet 22, fluid is from fuel feed hole 21, flow through in the water pipe 6, enter core head 5, flow out from oil outlet 22 at last, the first heat-resisting O type circle 7 is installed between plug mount pad 2 and core head 5, the second heat-resisting O type circle 8 is installed between socket for installation of water tube 1 and plug mount pad 2.Formed by institutes such as socket for installation of water tube 1, plug mount pad 2, plug pressing plate 3, mandrel body 4, core head 5 and water pipes 6, during work, the fluid of uniform temperature is inputted plug mount pads 2 from fuel feed hole 21, and in the oil-in 61 inflow water pipes (also can be described as oil pipe) of water pipe 6, from out flow through afterwards runner between water pipe and the core head 5 of oil pipe, temperature to plug is regulated and control, then from oil-out 11 and oil outlet 22 oil returns.The plug temperature control is regulated Main Function after injection moulding is finished, before blowing begins, because the temperature difference of parison at this moment at die parting line place and non-die parting line place directly has influence on the effect of blowing, temperature by the rising plug, come parison is heated again, dwindle parison in the temperature difference at die parting line place and non-die parting line place, reach the required temperature conditions of blowing.The technical program adopts be fluid as temperature control medium, can react to the temperature of plug rapidly, the temperature adjustment precision reaches ± 2 °.
