[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Example:

[0023] See also Figure 1-Figure 4 As shown, a barrel body injection mold includes a mounting base 1 and a movable mold 8. Vertical plates 2 are symmetrically and vertically arranged on the upper surface of the mounting base 1. Track rods 5 are arranged at the four corners between the two vertical plates 2. The four track rods 5 are parallel to each other. A fixed mold 4 is installed on the inner surface of one vertical plate 2, and a hydraulic cylinder 3 is arranged on the outer side of the other vertical plate 2. A movable plate 6 is slidably installed between the four track rods 5. The output end of the hydraulic cylinder 3 is fixed to the center of the surface of the movable plate 6 to control the movable plate 6 to move through the hydraulic cylinder 3, and to ensure that the movable plate 6 can only slide along the surface of the track rod 5. A docking groove 62 is symmetrically opened on the side surface of the movable plate 6 close to the fixed mold 4. The cross section of the docking groove 62 is conical, and the top of the docking groove 62 is open, so that the movable mold 8 can be installed from top to bottom, the docking groove 62 is a blind hole structure to support the movable mold 8 through the bottom, the movable mold 8 is placed on the side of the movable plate 6 close to the fixed mold 4, and the surface of one side of the movable mold 8 is symmetrically provided with docking strips 82, and the docking strips 82 are adapted to the internal dimensions of the docking groove 62, so that the movable mold 8 and the movable plate 6 can be installed through the cooperation of the two. A mold cavity 81 is provided on the side of the movable mold 8 away from the movable plate 6, and a corresponding mold cavity 81 is provided on the surface of the fixed mold 4. A lifting ring 83 is provided on the top of the movable mold 8 to facilitate lifting the movable mold 8 by a crane. A lifting ring 83 is also provided on the top of the fixed mold 4. Shaft sleeves 61 are provided at the four corners of the movable plate 6, and the track rod 5 passes through the shaft sleeves 61 to reduce the friction between the movable plate 6 and the track rod 5.

[0024] Please refer to Figure 2-Figure 4As shown, the top of the docking strip 82 is flush with the upper surface of the movable plate 6, so that the top of the docking strip 82 can be limited when the limit slide bar 65 slides. A boss 63 is provided in the center of the upper surface of the movable plate 6, and sliding holes 64 are symmetrically opened at both ends of the boss 63. A limit slide bar 65 is slidably installed inside the sliding hole 64. The limit slide bar 65 slides horizontally, and the limit slide bar 65 passes through the end surface of the boss 63. By controlling the movement of the limit slide bar 65, it can be controlled whether the limit slide bar 65 moves to the top of the docking groove 62. A fixed platform 68 is provided in the center of the upper surface of the boss 63, and a spring 66 is provided inside the sliding hole 64. One end of the spring 66 contacts the end surface of the limit slide bar 65. The elastic force of the spring 66 is used to make the limit slide bar 65 move outward when it is not restricted, so as to realize the limiting work of the movable mold 8.

[0025] Please refer to Figure 3 and Figure 4 As shown, a rotating shaft 7 is rotatably mounted at the center of the fixed platform 68, and a winding wheel 71 is provided at the bottom of the rotating shaft 7. The winding wheel 71 is placed inside the boss 63. The ends of the two limiting slides 65 that are close to each other are connected to a pull rope 67. The pull rope 67 passes through the spring 66. The ends of the two pull ropes 67 that are away from the limiting slide 65 are respectively connected to both sides of the surface of the winding wheel 71. Rotating the winding wheel 71 can pull the two pull ropes 67 at the same time to pull the two limiting slides 65 to retract into the sliding hole 64.

[0026] Among them, a square rod 72 is installed vertically sliding on the top of the rotating shaft 7, and a knob 73 is provided on the top of the square rod 72. The structure of the square rod 72 can ensure that the rotation of the knob 73 drives the rotating shaft 7 to rotate, thereby realizing the control of the winding wheel 71. At the same time, the square rod 72 can slide up and down, and a positioning pin 75 is provided on one side of the square rod 72. The positioning pin 75 has an L-shaped structure. Positioning holes 74 are evenly opened on the upper surface of the fixed platform 68 with the rotating shaft 7 as the center. The end of the positioning pin 75 is adapted to the internal size of the positioning hole 74, so that the other rod 72 can be limited by the cooperation of the two, so that the limiting slide 65 can be kept in a retracted state when the movable mold 8 is disassembled.

[0027] Working principle: The hydraulic cylinder 3 can control the movable plate 6 to slide along the surface of the track rod 5 to control the distance between the movable mold 8 and the fixed mold 4 to realize the opening and closing of the mold. After the mold is closed, ultra-high molecular weight polyethylene is injected into the mold cavity 81 to easily realize the injection molding of the barrel body. When the movable mold 8 needs to be replaced, the knob 73 can be lifted so that the positioning pin 75 no longer cooperates with the positioning hole 74. The rotation of the knob 73 drives the winding wheel 71 to rotate, and then the pull rope 67 is pulled to make the limit slide 65 move toward the inside of the slide hole 64. Then overlap it with the top of the docking groove 62, and then press down, and the positioning pin 75 cooperates with the corresponding positioning hole 74 to keep the rotating shaft 7 fixed. At this time, the movable mold 8 can be removed by the cooperation of the crane and the lifting ring 83. Conversely, when the new movable mold 8 is installed in place through the cooperation of the docking strip 82 and the docking groove 62, the knob 73 can be lifted to allow the winding wheel 71 to rotate. At this time, the elastic force of the springs 66 on both sides makes the limiting slide bar 65 pop outward to limit the top of the docking strip 82 and maintain the stability of the installation of the movable mold 8.

[0028] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
