Abstract
The blow-pressing die for the plastic hollow part with the flange is provided with a die, a core is arranged in the die, the die is connected with a bottom plate through a guide plate, a pushing and pressing chamber is arranged between the opening of the die and the core, a pressing plate is arranged in the pushing and pressing chamber, the outer end face of the pressing plate is connected with a push rod, the push rod penetrates through the bottom plate to be connected with a push plate, and the push plate is connected with a pushing and. The technology can be used for processing plastic hollow parts with a mouth part wall thickness larger than that of a parison, in particular to a flange. The plastic hollow part with the flange is convenient to connect and mount, and the strength is improved. The utility model discloses rational in infrastructure, simple, the investment is economized, convenient operation, the effect is reliable.
Description
The utility model belongs to device of plastic processing, is a kind of blow pressure mould that is specially adapted to produce the plastic hollow parts that has flange.
When producing the plastic hollow product, normally adopt the processing method of extrusion-blown modling in the past.At first extrude tubular parison, the parison of hot state is sandwiched in the blow mold, feed compressed air and carry out inflation, make its shape that reaches mould,, open mould then and take out finished product keeping cooling and shaping under certain pressure by extruder.Because the parison thickness unanimity that this processing method is extruded, if blowing oral area thickness just can't be realized greater than system of parison wall thickness or flanged (FLGD) hollow, though can achieve the goal if use the method for injection-blow molding instead, but make two secondary moulds is injection, each secondary mould of blowing, the processing trouble, equipment investment is big.
The purpose of this utility model be design a kind of have carry out simultaneously preform blowup and pushing structure, be specially adapted to process the blow pressure mould of the flanged or oral area wall thickness of oral area greater than the plastic hollow parts of parison thickness.
The blow pressure mould and the device of the processing plastic hollow that the utility model is designed, be that mould, core, base plate and dipper crowding gear etc. are formed, main inventive features is that a pushing chamber is arranged between the oral area of mould and core, the width of pushing chamber is decided on workpiece, its outer wall is equivalent to the outer rim size of plastic hollow parts oral area, if oral area is a flange, just be equivalent to the external diameter of flange.Push the indoor pressing plate that has, the outer face of pressing plate connects several push rods, push rod passes base plate and links to each other with push pedal, push pedal connects dipper crowding gear, dipper crowding gear drives push rod and pressing plate moves vertically, so-called dipper crowding gear can adopt hydraulic mechanism, air pressure mechanism or toggle etc., but with hydraulic pressure, the pneumatic drive to good.
The blow pressure mould of the flanged (FLGD) plastic hollow parts of processing of the present utility model can be processed the oral area wall thickness greater than parison, especially flanged (FLGD) plastic hollow parts.Flanged (FLGD) plastic hollow parts is gained in strength, and is convenient to be connected and installed.Present technique is relatively simple for structure, and reduced investment is easy to operate, and is effective.
Fig. 1 is the structural representation of the utility model blow pressure mould.
(1) hydraulic cylinder; (2) push pedal; (3) guide plate; (4) base plate; (5) push rod; (6) pressing plate; (7) be compressed the workpiece flange of moulding; (8) workpiece; (9) mould; (10) core; (11) pushing chamber; (12) piston rod.
Below in conjunction with Fig. 1 embodiment of the present utility model is elaborated.
The utility model has mould (9), is core (10) in the mould (9), and mould (9) connects base plate (4) by guide plate (3).Between the oral area of mould (9) and core (10), pushing chamber (11) is arranged, the width of pushing chamber (11) according to workpiece design decide, its outer wall is equivalent to the outer rim size of plastic hollow parts oral area, if oral area is a flange, just is equivalent to the external diameter of flange.In the pushing chamber (11) pressing plate (6) is arranged, the outer face of pressing plate (6) connects push rod (5), push rod (5) passes base plate (4) and links to each other with push pedal (2), push pedal (2) connects dipper crowding gear, dipper crowding gear is hydraulic pressure or air pressure, if hydraulic mechanism is hydraulic cylinder (1), the piston rod (12) in the hydraulic cylinder (1) is fixed on the base plate (4).
Blow pressure mould of the present utility model and device, push pedal (2) is made one with hydraulic cylinder (1) lid.
The utility model is enclosed within tubular parison on the core (10) when work, and mould (9) closure is clamped parison, feeds compressed air, and feed pressure oil in the hydraulic cylinder of tailpiece of the piston rod.Parison is blown into type under compressed-air actuated effect; Effect lower platen at hydraulic cylinder or cylinder is up, makes the indoor plastics of pushing be pressed into release behind the cooling and shaping such as flange, and pressing plate resets, and opens mould and takes out workpiece.
Claims (2)
1, a kind of blow pressure mould of flanged (FLGD) plastic hollow parts, by mould (9), in the mould (9) core (10), mould (9) connects base plate (4) by guide plate (3), it is characterized in that between the oral area of mould (9) and the core (10) pushing chamber (11) being arranged, in the pushing chamber (11) pressing plate (6) is arranged, the outer face of pressing plate (6) connects push rod (5), push rod (5) passes base plate (4) and links to each other with push pedal (2), and push pedal (2) connects dipper crowding gear.
2, the blow pressure mould of flanged (FLGD) plastic hollow parts as claimed in claim 1 is characterized in that the dipper crowding gear that push pedal (2) connects is hydraulic pressure or air pressure mechanism, and push pedal (2) is made one with the lid of hydraulic cylinder (1).
