Abstract
The present invention provides a forming die block enhanced cooling process of a plastic double-walled corrugated tube. At least one set of water supply pipelines, water pumping pipelines, vacuum pumping pipelines and blast cold pipelines are arranged above a right forming die block and a left forming die block. A cooling medium is continuously injected into cooling pipelines in the forming die blocks by the water supply pipelines. The cooling medium is continuously extruded out of the cooling pipelines by the water pumping pipelines to enable both ends of the outlets and the inlets of the cooling pipelines to form positive-negative pressure difference, and thus, the cooling medium fluently flows in the forming die blocks to enhance and cool the forming die blocks. At the same time, the vacuum pumping pipelines are used for vacuum pumping to vacuum passages in the forming die blocks which just enter a forming work position. Plastics at the outer layer of the plastic double-walled corrugated tube are absorbed on the inner walls of the forming die blocks to be formed and cooled. When the forming die blocks continuously advance and the plastic double-walled corrugated tube is basically cooled and shaped, cold air is blasted to the vacuum passages in the forming die blocks to enable the plastic double-walled corrugated tube and the surfaces of forming cavities in the forming die blocks to be enhanced and cooled simultaneously. The present invention also provides a forming die block enhanced cooling device of the plastic double-walled corrugated tube.
Description
Technical field:
The present invention is relevant with plastic double-walled corrugated pipe moulding and enlarging, and is relevant with enlarging module reinforcement cooling with the moulding of plastic double-walled corrugated pipe horizontal mode especially.
Background technology:
At present the mode that the moulding of plastic double-walled corrugated pipe horizontal mode and enlarging module are carried out cooling processing has 3 kinds: a kind of is directly to spray cooling water to the back side of module at the top of left and right sides module, water flows down from the back side of module and enters the lower header, the shortcoming of this mode is because module thickness is bigger, cooling water can not be fully with inside modules particularly a large amount of heats of the inner surface that directly contacts of module and bellows outer surface take away, cooling effect is poor, pipe workpiece quality and speed of production all are affected, and current splash everywhere; Another kind of as United States Patent (USP) DE19843340C2, the inlet opening that is the bottom by left and right sides module upwards is pressed into cooling water toward the inside modules pipeline, while also drains by the bottom discharge hole Jiang Shui of left and right sides module, the shortcoming of this mode is that hydraulic pressure can not be big, when hydraulic pressure is increased to greater than the module own wt a little, to up lift module, current let out from the slit of module baseplane and the two faying face that moves mutually of guide level, can not be fully in inside modules circulation cooling, the current of Guo Louing will have a strong impact on the evacuation passageway operate as normal of module bottom simultaneously; Also have a kind of mode such as German UNICOR company to adopt fast automatic plug to be installed and open and close joint at the module top, when module does not stop to move forward continuously, upper and lower, forward and back reciprocating motion that joint is done under driven by motor, with cooling water injection module internal duct discontinuously, the shortcoming of this mode is that the module cooling is insufficient, and mechanism's complexity owing to be to inject cooling water discontinuously, the upper and lower continually plug of joint makes very quick-wearing of seal, causes leakage.
Summary of the invention:
The objective of the invention is in order to overcome above deficiency, provide the plastic double-walled corrugated pipe forming module that a kind of moulding enlarging is stable, cooling effect is good to strengthen cooling means.
Another object of the present invention provides a kind of plastic double-walled corrugated pipe forming module and strengthens cooling device.
The object of the present invention is achieved like this:
Plastic double-walled corrugated pipe forming module of the present invention strengthen cooling means be with the left and right sides forming module of the synchronous forward movement of bellows above at least one group of supply channel is installed, pipeline draws water, vacuum-pumping pipeline and blast-cold air pipe, supply channel ceaselessly injects cooling medium to the cooling line of inside modules continuously, the pipeline that draws water is ceaselessly extracted cooling medium out continuously and is sent back in the collection box from cooling line, form positive and negative pressure with these import and outlet two ends at the cooling line of inside modules, allow cooling medium forming module be strengthened cooling in the smooth and easy circulation of inside modules, simultaneously, utilize the vacuum passage in the vacuum-pumping tube road direction module to vacuumize to the forming module that just enters the shaping work position, vacuum passage communicates with forming cavity in the forming module, the double-wall corrugated pipe outer layer plastic is adsorbed onto moulding and cooling on the module inwall, after the shaping mould piece continues to move ahead the basic cooling and shaping of tubing, utilize the vacuum passage blast-cold gas of blast-cold air pipe in module, make in tubing and the module cooling that strengthened simultaneously of forming cavity surface, hard-wired supply channel, pipeline draws water, adopt the plane to compress also intercommunication medium and sealing of the relative slip of laminating type between the forming module of vacuum-pumping pipeline and blast-cold air pipe and motion.
It is that supply channel injects cooling medium in the fixed plumbing container settled of the top of forming module passage or the pipeline to the left and right that above-mentioned plastic double-walled corrugated pipe forming module is strengthened cooling means, cooling medium is by being fixedly linked with plumbing container or pipeline, have at least one group of plumbing pressing plate of cooling medium inlet and outlet, or supply channel directly is connected with the plumbing pressing plate, enter install on module top and with the module proal at least one group of plumbing supporting plate that upwards holds up and be close to spring on the plumbing pressing plate baseplane simultaneously that be fixedly linked, import and export by the plumbing supporting plate are injected cooling medium to the cooling line of inside modules, exert pressure down at spring, fixed plumbing pressing plate baseplane and proal plumbing supporting plate top plan fit tightly the sliding channel of the sealing of formation energy intercommunication cooling medium mutually, make that cooling medium is smooth and easy to be entered the cooling line of inside modules and do not let out from the slit of plumbing pressing plate baseplane and the two faying face slideway that moves mutually of plumbing supporting plate top plan, the module of generating heat because of the moulding plastics double-wall corrugated pipe is fully cooled off, then with pump from the exit of the cooling medium of plumbing supporting plate end face with cooling medium by the plumbing pressing plate, in plumbing container or the pipeline suction collection box, under pumping action, the cooling line of inside modules is imported and exported and is formed positive and negative pressure, make cooling medium more unimpeded in pipeline, cooling effect is better, and need not increase inlet pressure, reduced sealing difficulty, moving to the pipeline that only draws water on the plumbing pressing plate on a group of the rearmost position or two pack module tops to the tubing Way out, the water that remains in the module is drained only, and stopped in module, to supply water.
