[0027] Please refer to Figures 1 - 7 Figures 1 - 7 , the present utility model provides a technical solution: a servo pump control for an injection molding machine, including a pump body 1, a controller 2 and an air tank 3.

The clamping plate 621 is arranged on the side of the fixing frame 611 away from the pump body 1. A threaded sleeve 622 is fixedly connected to the side of the clamping plate 621 away from the fixing frame 611. The threaded sleeve 622 is threadedly connected to the surface of the threaded rod 614. A guide sleeve 623 is fixedly connected to the side of the clamping plate 621 away from the fixing frame 611.

[0030] Specifically, an anti-slip knob 615 is fixedly connected to the side of the threaded rod 614 away from the pump body 1. By means of the anti-slip knob 615, it is convenient for the staff to rotate the threaded rod 614, so that the threaded rod 614 can be engaged with the threaded sleeve 622.

[0031] Specifically, a rubber bump 624 is fixedly connected to the side of the clamping plate 621 away from the pump body 1. A rubber gasket 625 is fixedly connected to the inner arc surface of the U-shaped frame 612.

[0032] In this embodiment: During the movement of the clamping plate 621, the rubber bump 624 can be pushed, so that the rubber bump 624 can abut against the surface of the power cord.

[0033] Specifically, the number of the U-shaped frames 612 is two. The two U-shaped frames 612 are symmetrically arranged up and down with respect to the fixing frame 611. The position of the power cord can be preliminarily constrained by the U-shaped frames 612 to ensure the stability of the power cord during the clamping process.

[0034] In this embodiment: The threaded rod 614 is rotatably connected to the inner wall of the fixing frame 611. The guide rod 616 is inserted into the inner wall of the fixing frame 611.

[0035] In this embodiment: Through the cooperation of the guide rod 616 and the guide sleeve 623, the moving direction of the clamping plate 621 can be guided.

[0036] Specifically, the clamping plate 621 is in contact with the surface of the U-shaped frame 612, the clamping plate 621 is sleeved on the surface of the threaded rod 614, and the clamping plate 621 is sleeved on the surface of the guide rod 616.

[0037] Specifically, the rubber bump 624 is semi-cylindrical, and the rubber gasket 625 is fixedly connected to the inner arc surface of the connecting frame 613.

[0038] In this embodiment: Through the cooperation of the rubber bump 624 and the rubber gasket 625, when the clamping plate 621 is locked, they can cooperate with each other to clamp the power cord inside the U-shaped frame 612.

[0039] Specifically, a support assembly is provided on the surface of the pump body. The support assembly includes a positioning block. The positioning block is fixedly connected to the side surface of the pump body. An L-shaped bracket is fixedly connected to the side of the positioning block away from the pump body. A load-bearing frame is slidably connected to the inner wall of the L-shaped bracket. A limiting spring is fixedly connected to the side surface of the load-bearing frame. The side of the limiting spring away from the load-bearing frame is fixedly connected to the inner wall of the L-shaped bracket. A latch is fixedly connected to the side of the load-bearing frame away from the limiting spring. A folding plate is rotatably connected to the inner wall of the L-shaped bracket. A buckle is fixedly connected to the side surface of the folding plate. A jack is opened at one end of the folding plate close to the L-shaped bracket. The latch is inserted into the inner wall of the jack. The position of the load-bearing frame can be restricted by the limiting spring to ensure the stability of the load-bearing frame in the locked state.

[0040] Working principle: When installing the power cord, pass the power cord through the U-shaped frame 612. When the power cord passes through the U-shaped frame 612, insert the power cord into the connector 5. Then, when the injection molding machine works, the control mechanism of the injection molding machine can control the cylinder, the pump body 1, the controller 2, and the motor 4 to work; after the connection of the power cord is completed, rotate the anti-slip knob 615 clockwise. The anti-slip knob 615 rotates the threaded rod 614. The threaded rod 614 meshes with the threaded sleeve 622. Under the action of the threaded rod 614, the threaded sleeve 622 pulls the clamping plate 621 in the direction of the power cord. The clamping plate 621 is guided by the guide rod 616 and the guide sleeve 623 to push the rubber bump 624. The rubber bump 624 approaches the power cord during the movement. When the rubber bump 624 abuts against the surface of the power cord, continue to rotate the anti-slip knob 615 clockwise so that the rubber bump 624 continues to squeeze the power cord. The power cord is squeezed against the surface of the rubber gasket 625. Immediately, with the cooperation of the rubber bump 624, the clamping plate 621, and the rubber gasket 625, the power cord can be clamped and restricted. By setting the assisting assembly 6, the power cord can be locked on the connector 5, thereby reducing the problem that the power cord accidentally loosens during use, resulting in equipment power supply failure, and further improving the stability of the equipment during use.

[0041] After the power cord is locked, insert the power cord into the buckle holder. The buckle holder clamps the power cord. When the installed power cord needs to be bent in another direction, push the load-bearing frame. The load-bearing frame pulls the latch pin under force and compresses the limit spring. The latch pin is pulled out of the jack and loses the lock on the folding plate. At the same time, the limit spring is compressed and deformed. When the folding plate loses the lock, rotate the folding plate to the left or right. With the assistance of the buckle holder, the folding plate drives the power cord to bend. After the folding plate rotates 90 degrees, release the load-bearing frame. The load-bearing frame loses the pressure exerted on the limit spring. The limit spring without pressure pushes the load-bearing frame to reset. The load-bearing frame pushes the latch pin to reset. The latch pin is inserted into the jack on the other side of the folding plate to re-lock the position of the folding plate. After the folding plate is locked, it can cooperate with the buckle holder to limit the bending direction of the power cord. By setting the support component, the pump control can guide the bending direction of the power cord to improve the stability of the power cord in the bent state.
