Embodiment 1

[0035] Embodiment 1: a kind of wall tube roller mold, such as figure 1 and 2As shown, it includes a cylinder body 1 and an annular skeleton 2 uniformly distributed in the inner cavity of the cylinder body 1 along the axial direction of the cylinder body 1 . The cylinder body 1 includes a base plate 11 , a first side plate 12 and a second side plate 13 enclosing a cylindrical structure, and the ring frame 2 includes a base frame fixed to the base plate 11 , the first side plate 12 and the second side plate 13 respectively. 21. The first frame 22 and the second frame 23, the first frame 22 and the second frame 23 are respectively rotatably connected to the base frame 21 and the opposite end faces of the first frame 22 and the second frame 23 are provided with slopes that guide and displace each other. A skeleton 22 can rotate inside the cylinder body 1 along the slope. A first connecting rod 31 and a second connecting rod 32 are respectively fixed through the first frame 22 an...

Embodiment 2

[0044] Embodiment 2: as Figure 4 As shown, the difference from Embodiment 1 is that the first adapter 5 includes two U-shaped first connecting plates 51 that are rotatably connected to the two first rotating shafts 33 and the two fixed sleeves 423 respectively, and are connected to the two second A connecting plate 51U-shaped non-open end telescopic rod 52, the middle part of the telescopic rod 52 is provided with a handle 522 and the two ends of the handle 522 are respectively provided with threaded parts 521 in opposite directions, and the threaded part 521 is connected with the two first connecting plates. 51 threaded connections respectively.

Abstract

The invention relates to a wall tube roller mold, which comprises a cylinder body and an annular skeleton distributed in the inner cavity of the cylinder body along the axial direction. The cylinder body includes a base plate, a first side plate, and a second side plate enclosing a cylindrical structure, and the ring frame includes a base frame, a first frame, and a second frame fixed to the base plate, the first side plate, and the second side plate, respectively. , the first frame and the second frame are respectively rotatably connected with the base frame and the opposite end surfaces of the first frame and the second frame are provided with slopes that guide and displace each other, and the first frame and the second frame are respectively provided with The first connecting rod and the second connecting rod; the base frame is provided with a transmission shaft along the axial direction of the cylinder, and a driving mechanism is provided on the base plate; through the linkage skeleton inside the cylinder, multiple cylinders that are closed into a cylindrical shape are realized. The deflection of the unit of the cylinder reduces the outer diameter of the cylinder, facilitates the separation of the formed product from the mold, realizes rapid demoulding, and greatly reduces or even eliminates the damage to the product during the demoulding process.

Description

technical field [0001] The invention relates to the field of wall tube forming molds, in particular to a wall tube roller mold. Background technique [0002] HDPE / PPH winding reinforced pipe is a new type of pipe that has been vigorously developed in my country in recent years. The process of winding and forming structural wall pipe is to extrude the plastic after melting, and extrude the flat material belt and U in the molten state from the die of the extruder. The profile belt is evenly wound on the heated roller mold according to the predetermined position, which ensures the quality of the welding seam of the structural wall pipe, and forms the structural wall pipe through the welding between the profiles. The advantage of this structure wall pipe is just can produce the pipe material of different diameter, different rigidity more easily by changing tire mold, is especially suitable for the plastic pipe that production diameter is very big (diameter is greater than 3 acryl...
