Abstract
Description
Technical Field
[0001] The utility model belongs to the field of injection molding, and particularly relates to a novel mold locking cylinder. Background Art
[0002] The clamping cylinder is an important part of the injection molding machine. It mainly injects a certain amount of pressure into the cylinder through the hydraulic system, so that the piston in the cylinder extends outward, thereby producing a clamping effect. Its main purpose is to lock the mold tightly on the template of the injection molding machine, ensuring that the mold maintains a stable position and close contact during the injection molding process, so as to ensure the quality and size stability of the injection molded product.
[0003] The existing clamping cylinder has certain problems in terms of sealing, such as loose sealing and easy leakage, which not only affects the normal operation of the injection molding machine, but also may cause damage to the mold and even cause safety accidents. Summary of the invention
[0004] The utility model aims to provide a novel anti-leakage clamping cylinder for the above-mentioned problems existing in the prior art.
[0005] The purpose of the utility model can be achieved through the following technical solutions: a new type of locking cylinder, including a cylinder body and an oil inlet and an oil outlet arranged on the cylinder body, characterized in that a piston rod for outputting energy is arranged in the cylinder body, and a piston for bearing the internal pressure of the cylinder body is arranged on the piston rod, an oil inlet chamber is arranged in the cylinder body, an anti-leakage component for preventing hydraulic oil leakage is arranged at the connection between the oil inlet chamber and the piston rod, a return spring is arranged on the anti-leakage component, and a movable push plate is connected to the return spring, and a sealing gasket for sealing is arranged on the push plate.
[0006] In the above-mentioned novel clamping cylinder, a sealing ring is arranged between the piston rod and the cylinder body.
[0007] In the above-mentioned novel clamping cylinder, the oil outlet is located in the oil cylinder body and an oil outlet cavity is provided.
[0008] In the above-mentioned novel clamping cylinder, support feet are arranged at the bottom of the cylinder body.
[0009] Compared with the existing technology, the new clamping cylinder effectively prevents the leakage of liquid media in high-pressure and high-speed working environments by optimizing the sealing structure. The excellent anti-leakage performance ensures the stable operation of the clamping cylinder and reduces the risk of safety accidents caused by leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0015] like Figure 1 , Figure 2 , Figure 3 As shown, the novel clamping cylinder comprises a cylinder body 1 and an oil inlet 2 and an oil outlet 3 arranged on the cylinder body 1. A piston rod 4 for outputting energy is arranged in the cylinder body 1, and a piston 5 for bearing the internal pressure of the cylinder body 1 is arranged on the piston rod 4. The oil inlet 2 is located in the cylinder body 1 and an oil inlet cavity 6 is arranged. An anti-leakage component 7 for preventing hydraulic oil leakage is arranged at the connection between the oil inlet cavity 6 and the piston rod 4. When the hydraulic oil enters the cylinder body 1 from the oil inlet 2 and flows through the oil inlet cavity 6, the anti-leakage component 7 will be affected by the pressure of the hydraulic oil. Open to allow the hydraulic oil to enter smoothly. When the pressure becomes smaller and smaller, the anti-leakage component 7 will gradually close as the pressure decreases to prevent the piston rod 4 from causing leakage of hydraulic oil during movement. The anti-leakage component 7 is close to the piston rod 4. A return spring 8 is provided on the anti-leakage component 7, and a movable push plate 9 is connected to the return spring 8. The push plate 9 moves under the influence of pressure. A sealing gasket 10 for sealing is provided on the push plate 9. When the anti-leakage component 7 is close to the piston rod 4, the sealing gasket 10 will press the piston rod 4 for sealing.
[0016] To be more specific, a sealing ring 11 is provided between the piston rod 4 and the cylinder body 1 .
[0017] In further detail, the oil outlet 3 is located in the oil cylinder body 1 and is provided with an oil outlet cavity 12 .
[0018] To be more specific, a supporting foot 13 is disposed at the bottom of the oil cylinder body 1 .
[0019] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
[0020] Although the terms such as oil cylinder body 1, oil inlet 2, oil outlet 3, piston rod 4, piston 5, oil inlet chamber 6, anti-leakage assembly 7, return spring 8, push plate 9, sealing gasket 10, sealing ring 11, oil outlet chamber 12, support foot 13 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
