[0026] Among them, the ejector rod assembly 25 includes a sealing cavity 251 opened inside the bottom mold 21, a connecting cavity 252 is further opened inside the sealing cavity 251, the connecting cavity 252 is communicated with one side of the sealing cavity 251 away from the mold cavity 23, and the inner diameter of the sealing cavity 251 is larger than the inner diameter of the connecting cavity 252; due to the arrangement of the connecting cavity 252, it can ensure that the second infusion tube 6 can be well communicated with the sealing cavity 251, and then under the action of hydraulic oil, the piston plate 253 drives the ejector rod 254 to reciprocate.

[0027] Among them, a piston plate 253 is hermetically sleeved inside the sealing cavity 251. On the side of the outer surface of the piston plate 253 away from the communication cavity 252, a number of ejector rods 254 are fixedly connected. One end of the ejector rod 254 away from the piston plate 253 penetrates through the sealing cavity 251 and extends into the interior of the mold cavity 23, and the end of the ejector rod 254 away from the piston plate 253 is flush with the inner wall of the mold cavity 23.

[0028] Among them, the demolding auxiliary part 26 includes a limiting groove 261 opened on the front surface of the bottom mold 21. A clamping groove 262 is opened inside the bottom mold 21. The clamping groove 262 communicates with the limiting groove 261. The inner diameter dimension of the limiting groove 261 is smaller than the inner diameter dimension of the clamping groove 262. One end of the limiting groove 261 extends into the interior of the mold cavity 23, and one end of the clamping groove 262 is not connected to the mold cavity 23; due to the arrangement of the limiting groove 261 and the clamping groove 262, it can ensure that the slider 263 can reciprocate, and at the same time, it can prevent the slider 263 from completely disengaging from the limiting groove 261 and the clamping groove 262.

[0030] At the other ends of the inner cavities of the limiting groove 261 and the clamping groove 262, a positioning spring 264 is arranged. One end of the positioning spring 264 is connected to the inner walls of the limiting groove 261 and the clamping groove 262, and the other end of the positioning spring 264 is connected to the slider 263; due to the arrangement of the positioning spring 264, it can ensure that the mold core 24 can be smoothly inserted into the mold cavity 23, and at the same time, it can block the reverse movement of the formed butt welding column, so that the ejector rod 254 can disengage from the formed butt welding column to complete demolding.

[0031] Among them, a chute 4 is opened at the top of the base 1. Two left and right sliders are slidably clamped inside the chute 4. The tops of the two sliders extend above the chute 4 and are respectively fixedly connected to the bottoms of the bottom mold 21 and the top mold 22.

[0032] Among them, a hydraulic rod 3 is connected to the opposite surfaces of the bottom mold 21 and the top mold 22. The opposite distal ends of the two hydraulic rods 3 are respectively installed at both ends of the base 1. A first infusion pipe 5 is connected between the opposite distal ends of the two hydraulic rods 3. A second infusion pipe 6 is connected to the middle of the first infusion pipe 5. The other end of the second infusion pipe 6 is fixedly connected to the bottom mold 21 and communicates with the communication cavity 252;

[0033] Solenoid valves 7 are arranged on both the left and right sides of the first infusion pipe 5 on the side of the second infusion pipe 6, and a solenoid valve 7 is also arranged on the second infusion pipe 6. The first infusion pipe 5 and the second infusion pipe 6 are connected to a hydraulic pump through a hose.

[0034] The working principle and usage process of the present utility model:

[0035] With the cooperation of the first infusion tube 5 and the solenoid valve 7, hydraulic oil enters the hydraulic rod 3, and then, with the cooperation of the base 1 and the chute 4, the bottom die 21 and the top die 22 move, thus achieving the purpose of mold opening and mold closing;

[0036] After mold opening, with the cooperation of the second infusion tube 6 and the solenoid valve 7, hydraulic oil enters the sealing cavity 251 through the communication cavity 252, and under the restriction of the sealing cavity 251, the piston plate 253 is pushed. Due to the movement of the piston plate 253, the ejector rod 254 can be pushed to move, and then its front end moves in the mold cavity 23, and the butt-welding column formed in the mold cavity 23 can be ejected, so that the butt-welding column can be separated from the mold cavity 23. At this time, when the hydraulic oil is withdrawn, the ejector rod 254 can move in the opposite direction with the cooperation of the communication cavity 252, the sealing cavity 251 and the piston plate 253, and reset to the position where its front end is flush with the inner wall of the mold cavity 23; if there is adhesion between the front end of the ejector rod 254 and the formed butt-welding column, when the ejector rod 254 retracts, the formed butt-welding column can be separated from the ejector rod 254 under the block of the slider 263, thus quickly completing demolding.
