DETAILED DESCRIPTION

[0014] Referring to Figure 1 、 Figure 2 , four cavity silica gel pipe production mould of the utility model, including main body block 1, template 2, module 3, fixed rod 31, movable rod 41, movable block 4, pneumatic cylinder 40, the inside of main body block 1 is equipped with an installation channel 10, installation channel 10 is through the both sides of main body block 1, and installation channel 10 one end is fixedly installed with the vertically arranged template 2, and the template 2 is equipped with a horizontally arranged die hole 20, and the die hole 20 is through the both ends of template 2, and installation channel 10 inside is fixedly installed with a module 3, and the end face of module 3 close to template 2 is fixed with two horizontally arranged fixed rods 31, and the axis direction of fixed rod 31 is parallel with die hole 20, and fixed rod 31 extends into die hole 20 inside, the inside wall of template 2, installation channel 10, module 3 jointly encloses a feeding cavity 11, and the main body block 1 is equipped with a feeding hole 15, and the feeding cavity 11 is only connected with feeding hole 15 and die hole 20, the module 3 is equipped with two parallel guide holes 35 with fixed rod 31, and the guide hole 35 is through the both ends of module 3, the movable block 4 is located at the side of module 3 away from template 2, and the movable block 4 is fixed with two movable rods 41 corresponding with guide hole 35, and the movable rod 41 is adapted to guide hole 35, and the movable rod 41 is passed through the corresponding movable rod 41, the movable block 4 is connected with a pneumatic cylinder 40, and the pneumatic cylinder 40 drives movable block 4 to move along the direction parallel to movable rod 41.

[0015] A cutting mechanism 5 is provided on the outside of the main block 1, and the cutting mechanism 5 is located on the side of the template 2 away from the module 3.

[0016] The module 3 has a guide platform 30 near the template 2. The guide platform 30 is a horizontally arranged truncated cone. The guide platform 30 and the mold hole 20 are located on the same central axis. The end of the guide platform 30 near the template 2 is the minimum outer diameter of the guide platform 30.

[0017] A portion of the motion trajectory of the movable rod 41, which is away from the end of the movable block 4, is located inside the die hole 20.

[0018] The working process of this utility model:

[0019] In operation, the four-cavity silicone tube production mold of this utility model is installed on the extruder. The mold is initially in state A, i.e. Figure 1 The end of the movable rod 41 shown is on the same vertical plane as the end of the module 3. The raw material flows into the feeding chamber 11 from the feeding hole 15 and exits from the die hole 20. Since there are only two fixed rods 31 in the die hole 20 at this time, the extruded silicone tube has only two cavities. After extrusion for a period of time, the cylinder 40 drives the movable block 4 and the movable rod 41 on the movable block 4 to move until a part of the movable rod 41 enters the die hole 20. At this time, it is as follows. Figure 2 In state B, there are two fixed rods 31 and two movable rods 41 inside the die hole 20. The extruded silicone tube has four cavities. After extrusion for a period of time, the cutting mechanism 5 cuts the silicone tube. At this time, there are four cavities at the cut surface. Then, extrusion continues for a period of time. Then, the cylinder 40 drives the movable rod 41 to reset, and the die returns to state A. At this time, the extruded silicone tube has two cavities. After extrusion for a period of time, the cutting mechanism 5 cuts the silicone tube. At this time, there are two cavities at the cut surface. Then, extrusion continues for a period of time. Then, the die returns to state B. In this way, the die switches between state A and state B while continuously extruding. The cutting mechanism 5 cuts the silicone tube in an orderly manner, realizing the production of a four-cavity silicone tube.
