Abstract
The utility model discloses a mould, which is mainly used for the prominence of the connecting end head of a plastic pipe, comprising an outer mould 1 and an inner mould 2. The utility model is characterized in that the outer mould 1 is provided with two different inner diameters, and the inner mould 2 is provided with two different outer diameters. A ring groove 4 is arranged between the two outer diameters of the inner mould 2. The inner mould 2 is sheathed in the outer mould 1, and is limited by the limiting baffle edge of the inner mould 2. An interstice 6 is arranged between the end head of the outer wall of the ring groove of the inner mould 2 and the inner dummy club 5 of the outer mould 1. The utility model has the advantages that an outer circumference convex edge which is connected with the wall of the plastic pipe as an integral can be processed. The structure is simple, and the process precision is high.
Description
The utility model relates to a kind of mould, and particularly a kind of mould that is used for the plastic tube blistering belongs to technical field of mold.
Existing mould kind is more, but does not have a kind of mould that is used for the plastic tube blistering.Treat blistering, greatly linking intensity between the reinforced plastic pipes and sealing on the circumference of union end at plastic tube.But, all be not with the excircle chimb on the outer circle wall at hard plastic tube two ends at present, connection between the hard plastic tube is mainly by bonding, thread connection and pipe fitting connect, but it is low all to have linking intensity, and sealing is poor, and the low deficiency of easily breaking that causes of pressure is born in the connection place, influenced the application of plastic tube, slowed down to mould the speed of Dai Gang.
The purpose of this utility model provides a kind of mould, utilizes outer wall that it can make plastic tube along the circumference blistering, forms the outer chimb of circumference, is convenient to the connection between the plastic tube, increases the intensity and the sealing of connection place.
The purpose of this utility model is achieved through the following technical solutions.This mould is made up of external mold 1 and internal mold 2, and its special character is, external mold 1 is two die sinkings, and the cavity of external mold 1 has d
1, d
2Two internal diameters, inner diameter d
1Greater than inner diameter d
2Internal mold 2 is enclosed within the cavity of external mold 1, and is provided with spacing shelves limit 3 at an end of internal mold 2; Internal mold 2 has d
3, d
4Two external diameters, outside diameter d
3Greater than outside diameter d
4, and between two external diameters, being provided with circumferential groove 4, the width of this circumferential groove equals the external mold inner diameter d
2With the internal mold outside diameter d
4Difference 1/2nd.The thickness of circumferential groove 4 outer walls is slightly less than the external mold inner diameter d
1With its inner diameter d
2Difference 1/2nd, and between the inner convex platform 5 of the termination of circumferential groove 4 outer walls and external mold 1, leave space 6.The width of external mold inner convex platform 5 is slightly larger than the outer wall thickness of circumferential groove 4.External mold 1 inner diameter d
1, d
2Size and internal mold 2 outside diameter d
3, d
4Size be directly proportional with the diameter for the treatment of the blistering plastic tube, wall thickness, the width of circumferential groove 4 is slightly larger than the wall thickness for the treatment of the blistering plastic tube.The width in space 6 is directly proportional with the size of institute's blistering.
A kind of embodiment preferably of the utility model is, internal mold 2 is the open-core type inner membrance, and the hollow wall of this internal mold is provided with internal thread.Can use steel less like this, alleviate the weight of internal mold, be convenient to connecting of internal mold and drive unit.
Second kind of the utility model embodiment preferably be, is provided with alignment pin 7 on a half module of external mold 1, establishes on another half module and the alignment pin corresponding positioning hole.
The utility model the third preferably embodiment be, on the sidewall at two ends, external mold 1 bottom, be provided with gathering sill 8, can simplify mould and the connection of waiting to connect base like this.
Because the utility model has adopted above-mentioned technical solution, make it compared with prior art, can be on the outer circle wall of plastic tube union end blistering, form an excircle chimb that combines as a whole with outer wall, both be convenient to the connection between the plastic tube, the intensity and the sealing of plastic tube connection place have been increased again, for the application that enlarges plastic tube provides a kind of desirable processing mold.
The explanation of accompanying drawing drawing
The structural representation of an embodiment of Fig. 1-the utility model
The A-A of Fig. 2-Fig. 1 is to cutaway view
Fig. 3-put into the structural representation that mould forms the excircle chimb by the blistering plastic tube
Provide embodiment of the present utility model below in conjunction with accompanying drawing, be used for further specifying technical solution.
Embodiment is with reference to figure 1-Fig. 3.This is that an appearance is square, and endoporus is the mould of circular port.There is gathering sill 8 external mold 1 bottom on the two side, and alignment pin is two, lays respectively on the diagonal corner of a half module, and locating hole is positioned at the corresponding position of another half module.The inner diameter d of external mold 1 cavity
1=70MM, inner diameter d
2=65MM.Internal mold 2 is the open-core type internal mold, is provided with internal thread on the hollow wall of this internal mold, its outside diameter d
3=69.6MM, outside diameter d
4=59MM, the width of circumferential groove 4 equals (d
2-d
4)/2=(65-59)/2=3 (MM), space 6 is 3MM.Thick (the d that is slightly less than of circumferential groove 4 outer walls
1-d
2)/2=(70-65)/2=2.5 (MM).Find out the outside diameter d of the aperture of plastic tube 9 and internal mold 2 by Fig. 3
4Matching, also is that plastic tube 9 is matched in clearance with internal mold 2, and the excircle chimb 10 that is risen just in time is positioned at space 6.This mould is as follows to the process of plastic tube blistering: in the place of blistering, earlier with heater heating of plastic pipe 9, make the local deliquescing of plastic tube, when waiting to reach requirement, plastic tube is inserted in the mould, at this moment plastic tube 9 is between external mold 1 and internal mold 2, heated plastic tube wall just in time is positioned at 6 pairing positions, space, apply a thrust to plastic tube, push inward internal mold 2 simultaneously, at this moment heated plastic tube is under the pressure at two ends, and the softening plastics of part are pressed against in the space 6, after cooling, just formed the excircle chimb 10 that combines as a whole with outer wall.Loosening internal mold 2 makes the movable mold of external mold 1 leave plastic tube 9 simultaneously, and at this moment, locating hole and alignment pin 7 break away from, and make plastic tube 9 leave mould 1, have just finished the process at plastic tube one end blistering.If make the other end blistering of plastic tube, repeat above process and just can.
In like manner, according to claim 1,2,3 technical schemes that limit, cause and to provide the mould that three kinds of structures form less.Here narration no longer one by one, use is similar, but machining accuracy and manufacturing cost are all poor slightly than the foregoing description.
