A kind of device of regulating plastic pipe mould die slot thickness
Technical field
The utility model relates to the technical field of plastic pipe mould, is specifically related to a kind of device of novel die slot thickness in can free adjustment plastic pipe mould.
Background technology
In the middle of the process of plastic pipe mould, because many-sided influences such as plastic pipe Mould Machining precision, assembly precision and processing technology, material behavior, when the mould extruding pipe material, tend to occur the tube wall thickness non-uniform phenomenon, for addressing this problem, the device of design adjusting die slot thickness is present more common a kind of method on pipe mold.But, the method that the existing device of regulating die slot thickness is taked is provided with around the mouth mould of mould normally that method that set screw radially is set realizes, this method is simple and practical, but must there be enough spaces to realize around the mould, so will have restriction on the space for the mould of a mould multitube, simultaneously, continuing to use the method that the radiai adjustment screw is set around mouthful mould is to realize by the centre-to-centre spacing that strengthens between tubing, and removing like this increases the difficulty that die cost also can increase the cost of equipment outward and increase operation.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, thereby a kind of novel die slot thickness adjusting apparatus that the set screw axial arranging has been reduced the mould radial space is provided.
The utility model is achieved by the following technical programs:
A kind of device of regulating plastic pipe mould die slot thickness comprises core rod, prosopyle mould, axial adjustment screw, pressure ring set bolt, pressure ring, deutostoma mould, die holder.
Prosopyle mould band spill sphere, deutostoma mould band convex spherical, the prosopyle mould has identical diameter with the sphere of deutostoma mould, and the prosopyle mould cooperates the location by its sphere with the deutostoma mould, and can be along sphere rotation and slight swing.
Be provided with core rod in the deutostoma mould, core rod and deutostoma mould all are connected on the die holder, and in addition, the part that core rod extends the deutostoma mould is surrounded by the prosopyle mould outward; The outside junction of prosopyle mould and deutostoma mould is fixed by pressure ring is nested, and pressure ring is fixed on the deutostoma mould by the pressure ring set bolt.
The pressure ring set bolt is provided with vertically.
Wherein, the axial adjustment screw is provided with vertically, pressure ring is fixed on the prosopyle mould, and then further carries out prosopyle mould and deutostoma mould fastening; The quantity of axial adjustment screw is 4, is symmetrically distributed on the prosopyle mould in the mode of upper and lower, left and right.By regulate simultaneously up and down or about the axial adjustment screw, the prosopyle mould is slightly swung to required direction along sphere, thereby regulated the size in die slot gap.
Usefulness of the present utility model is:
The utility model has designed a kind of device of regulating plastic pipe mould die slot thickness, utilize the principle that but any direction slides between two spheres, the set screw that will be used for the adjusting of tubing die slot thickness transfers axial arranging to by radially arranging, the installation site and the operating space of the set screw of originally radially arranging have been saved, reduced the centre-to-centre spacing between tubing in the mould multitube mould, realized reducing the effect of die size, reached the purpose of being convenient to production operation, greatly reduce job costs simultaneously, be convenient to production operation, possess excellent application performance.
Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, a kind of device of regulating plastic pipe mould die slot thickness comprises core rod 1, prosopyle mould 2, axial adjustment screw 3, pressure ring set bolt 4, pressure ring 5, deutostoma mould 6, die holder 7.
Prosopyle mould 2 band spill spheres, deutostoma mould 6 band convex sphericals, prosopyle mould 2 has identical diameter with the sphere of deutostoma mould 6, and prosopyle mould 2 cooperates the location by its sphere with deutostoma mould 6.
Be provided with core rod 1 in the deutostoma mould 6, core rod 1 all is connected on the die holder 7 with deutostoma mould 6, and in addition, the part that core rod 1 extends deutostoma mould 6 is surrounded by prosopyle mould 2 outward; The outside junction of prosopyle mould 2 and deutostoma mould 6 is by pressure ring 5 nested fixing, and pressure ring 5 is fixed on the deutostoma mould 6 by pressure ring set bolt 4.
Pressure ring set bolt 4 is provided with vertically.
Wherein, axial adjustment screw 3 is provided with vertically, pressure ring 5 is fixed on the prosopyle mould 2, and then further carries out prosopyle mould 2 and deutostoma mould 6 fastening; The quantity of axial adjustment screw 3 is 4, is symmetrically distributed on the prosopyle mould 2 in the mode of upper and lower, left and right.
The die slot of mould is the distance between core rod 1 and the prosopyle mould 2, the die slot size is to be determined by the core rod 1 and the relative position of prosopyle mould 2, wherein, core rod 1 and deutostoma mould 6 positions are changeless, but the prosopyle mould 2 of band spill sphere can be along the sphere fine rotation, axial adjustment screw 3 below the loosening prosopyle mould 2, tighten up the axial adjustment screw 3 above the prosopyle mould 2 simultaneously, then can be along the slightly upwards transhipment of the centre of sphere of sphere with the prosopyle mould 2 of spill sphere, thereby make the last die slot of mould become big, and die slot diminish down.
In addition, axial adjustment screw 3 by loosening prosopyle mould 2 left sides tightens up the axial adjustment screw 3 on prosopyle mould 2 right sides simultaneously, then can be along the slightly transhipment to the right of the centre of sphere of sphere with the prosopyle mould 2 of spill sphere, thereby make the right die slot of mould become big, and left die slot diminish.
By the operation of these some series, reached the purpose of regulating die slot thickness.
