Abstract
The utility model discloses a pressure control device which structurally includes a hopper, a machine barrel, a screw rod, a storage cylinder, a die, a pressure control oil cylinder and proximity switches, wherein the cylindrical machine barrel is vertically mounted; the hopper is arranged at the top of the machine barrel; the screw rod is arranged inside the machine barrel; the storage cylinder is arranged beside the bottom end of the machine barrel and communicated with the die through an injection nozzle; the pressure control oil cylinder is arranged on the upper side of the storage cylinder; the lower end of the pressure control oil cylinder is communicated with the storage cylinder through a plunger; the upper end of the pressure control oil cylinder is connected with a sliding block through a piston rod; and the two proximity switches are arranged on the upper and the lower sides of the sliding block respectively. The pressure control device has simple structure, smaller size, stable pressure maintaining for a melt inside the die, short work cycle and high equipment operating efficiency.
Description
Technical field
The utility model relates to a kind of pressure control device, relates in particular to a kind of fusion and injects the pressure control device that carries out and can shorten barrel length simultaneously.
Background technology
Existing melt pressure control device comprises the screw rod that is arranged in the machine barrel, in the leading section machine barrel of screw rod, is provided with the cavity that can hold plastic melt, and cavity outlet end and mould link, and the rearward end of screw rod is connected with two injection cylinders; When screw rod rotates, also can do axially-movable along machine barrel in machine barrel, when this device uses, screw rod rotation preformed; Melt pressure raises in the mould of machine barrel front end, the mould pressurize, and screw rod receives the effect of front end melt pressure, motion backward vertically in machine barrel; Along with the continuous rotation of screw rod, the plastics material for making clothes at machine barrel rear portion is constantly plastified and is transported to the front end of screw rod, when screw rod retreats into the precalculated position; Spiro rod plasticizing stops, and at this moment, has just stored enough melts between screw front end and the mould; After the anti-saliva action of screw rod completion, melt pressure descends, moulds open.Treat mould once more behind the matched moulds, screw rod travels forward under the drive of two injection cylinders, and the melt of fusion is injected mould, and when waiting screw rod to be advanced to the precalculated position, injection finishes.
This molding machine melt pressure control device has following deficiency: the fusion of plastics is separately carried out with injection in the device, so increases its service cycle, and production efficiency is not best; Simultaneously, this device comes the melt in the mould is carried out pressurize through the rotation of screw rod, therefore; Its pressurize less stable, in addition, because screw rod moves axially in machine barrel; The leading section that is machine barrel is provided with the cavity that holds melt, and therefore, its barrel length is longer relatively.
Summary of the invention
The purpose of the utility model gram is to provide a kind of fusion and injection to carry out simultaneously, and pressurize is more stable, and can shorten the melt pressure control device of barrel length.
The purpose of the utility model is to realize through following technical scheme:
The utility model discloses a kind of pressure control device, its structure is controlled oil cylinder, is formed near switch by hopper, machine barrel, screw rod, accumulator, mould, pressure, and wherein machine barrel is uprightly installed; Be cylindric; The machine barrel top is provided with hopper, is provided with screw rod in the machine barrel, and machine barrel bottom side is provided with accumulator; The accumulator side is provided with mould; The accumulator upside is provided with pressure control oil cylinder, and pressure control oil cylinder upper end is connected with slide block through piston rod, and the upper and lower sides of slide block is respectively arranged with two near switch.
Described hopper divides two parts shape, and the first half is cylindric, and the latter half is coniform, and the circular cone waist is equipped with charging aperture.
Described pressure control oil cylinder lower end is communicated with accumulator through plunger.
Described accumulator is connected with mould through nozzle.
Owing to adopted above technical scheme, it is simple to the utlity model has apparatus structure, and volume is less, uses more reliable; Stable to the melt pressurize in the mould; Work period shortens, and the equipment operating efficiency improves.
Description of drawings
Fig. 1 is the structure chart of the utility model pressure control device.
Among the figure: 1-hopper, 2-screw rod, 3-machine barrel, 4-accumulator, 5-nozzle, 6-mould, 7-piston rod, 8-pressure control oil cylinder, 9-plunger, 10-slide block, 11-are near switch.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described:
Embodiment 1: a kind of pressure control device, and its structure is controlled oil cylinder, is formed near switch by hopper, machine barrel, screw rod, accumulator, mould, pressure, and wherein machine barrel is uprightly installed; The machine barrel top is provided with hopper; Be provided with screw rod in the machine barrel, machine barrel bottom side is provided with accumulator, and accumulator links through nozzle and mould; The accumulator upside is provided with pressure control oil cylinder; Pressure control oil cylinder lower end is communicated with accumulator through plunger, and pressure control oil cylinder upper end is connected with slide block through piston rod, and the upper and lower sides of slide block is respectively arranged with two near switch.
Embodiment 2: when a kind of pressure control device was worked, screw rod rotated in machine barrel, and plastic pellet is carried downwards; And fusion plastification, after the melt of fusion plastification was full of mould, the melt pressure in the accumulator rose; When melt pressure rose to the active force that is enough to overcome pressure control oil cylinder, plunger moved upward, and promoted the piston rod of pressure control oil cylinder and the slide block at top thereof and moved upward together; Dwell pressure is provided by pressure control oil cylinder, after pressurize finishes, and the screw rod counter-rotating; Melt pressure in the accumulator descends, and the slide block that the piston rod of pressure control oil cylinder drives its end moves downward, up to trigger its underpart near switch; Screw rod stops counter-rotating, waits for getting into next cycle.
What should explain at last is: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; All do not break away from the effect of the utility model and the technical scheme and the improvement thereof of scope, and it all should be encompassed in the claim scope of the utility model.
