Description

Technical Field

[0001] This utility model relates to the field of O-ring production, and in particular to a high-efficiency cooling mold for O-ring production. Background Technology

[0002] The high-efficiency cooling mold for O-ring production is a mold device used to improve the production efficiency and quality of O-rings.

[0003] In existing O-ring manufacturing processes, after the rubber material is injected into the mold cavity, a cooling medium (usually cooling water) circulates through cooling channels. The cooling medium absorbs heat from the mold surface, causing the rubber to cool and solidify rapidly. Because the cooling channels are designed to ensure uniform distribution of the cooling medium, the rubber ring shrinks evenly during cooling, resulting in good dimensional accuracy and surface quality.

[0004] However, in actual use, the cooling medium carries impurities and scale during long-term circulation. These substances easily accumulate in the cooling channels, causing blockage. Once the cooling channels are blocked, the flow rate of the cooling medium will decrease, and the cooling effect will drop significantly. This will not only prolong the production cycle but may also damage the mold or affect product quality due to localized overheating. Therefore, in response to the above problems, a high-efficiency cooling mold produced by O-ring rubber seals has been developed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a high-efficiency cooling mold for the production of O-ring rubber seals, which aims to solve the problem in the prior art that "the cooling medium carries some impurities, scale, etc. during long-term circulation, and these substances are easy to accumulate in the cooling channel".

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency cooling mold for producing O-ring rubber seals, comprising a mold body, a forming groove on the top of the mold body, a circular cooling pipe fixedly connected to the top of the mold body, a circulation pipe fixedly threaded to the back of the mold body, a switching mechanism provided on the front surface of the mold body, a metering mechanism provided inside the switching mechanism, the switching mechanism including a connecting pipe B, a connecting pipe A fixedly connected to the outer wall of the mold body, the connecting pipe B threadedly connected to the outer wall of the connecting pipe A, a coolant inlet fixedly connected to the top of the connecting pipe B, a cleaning agent A inlet fixedly connected to the left side of the outer wall of the connecting pipe B, a cleaning agent B inlet fixedly connected to the right side of the outer wall of the connecting pipe B, a rotating shaft fixedly connected to the inner wall of the connecting pipe B, a connecting rod B rotatably connected to the inner wall of the rotating shaft, a connecting rod A fixedly connected to the outer wall of the rotating shaft, and a sealing ball slidably connected to the top of the connecting rod A.

[0007] As a further description of the above technical solution: a spring A is fixedly connected to the outer wall of the rotating shaft, and the top end of the spring A is fixedly connected to the outer wall of the sealing ball.

[0008] As a further description of the above technical solution: a toothed knob is slidably connected to the inner wall of the connecting rod B, a knob B is fixedly connected to the outer wall of the toothed knob, a spring B is fixedly connected to the outer wall of the connecting rod B, and the top end of the spring B is fixedly connected to the back of the toothed knob.

[0009] As a further description of the above technical solution: the quantitative mechanism includes a connecting rod C, which is rotatably connected to the outer surface of the connecting tube B. A limit rod is fixedly connected to the outer surface of the connecting tube B, and an active turntable is inserted into the outer wall of the connecting rod C.

[0010] As a further description of the above technical solution: the inner wall of the connecting pipe B is rotatably connected to a connecting rod D, the inner extension end of the connecting rod D is fixedly connected to a ball, and the outer extension end of the connecting rod D is fixedly connected to a driven disc.

[0013] As a further description of the above technical solution: there are two sets of connecting rod A, spring A and sealing ball, and the two sets of connecting rod A, spring A and sealing ball are symmetrically arranged at the left and right ends of the rotating shaft.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the quantitative mechanism uses the connecting rod C, limiting rod, active turntable, connecting rod D, ball, driven plate, and bolt to cooperate with each other to achieve quantitative control of the cleaning agent. Rotating the active turntable drives the driven plate to rotate, and the driven plate drives the ball to rotate through the connecting rod D, controlling the opening and closing angle of the cleaning agent inlet to achieve quantitative injection of the cleaning agent (dissolving and cleaning the internal scale through chemical agents). When unequal injection is required, the active turntable can be removed and the driven plate rotated separately.

Connecting pipe B connects each inlet to the mold body. Pressing down knob B disengages the toothed knob from the toothed ring, and rotating the connecting rod causes the sealing ball to change position. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3This utility model provides an embodiment of a high-efficiency cooling mold for producing O-ring rubber seals, comprising a mold body 1, which is the basic structure of the entire cooling mold and provides installation support for other components. A forming groove 2 is formed on the top of the mold body 1. The forming groove 2, located on the top of the mold body 1, is a key part in the forming of the O-ring rubber seal, providing a specific shape space for the rubber raw material so that it can be formed into the required O-ring rubber seal. A circular cooling pipe 3 is fixedly connected to the top of the mold body 1. Its function is to remove the heat generated during the forming process of the O-ring rubber seal through the circulation of coolant, accelerating the cooling and solidification of the rubber. A circulating cooling pipe is fixedly threaded to the back of the mold body 1. Pipe 4 is used to circulate the coolant within the circular cooling pipe 3, ensuring that the coolant can continuously and effectively remove heat and maintain the stability of the cooling effect. A switching mechanism 6 is provided on the front surface of the mold body 1, which controls the inlet and outlet channels of the coolant, cleaning agent A, and cleaning agent B, switching them according to different working requirements. A metering mechanism 7 is provided inside the switching mechanism 6 to precisely control the injection volume of cleaning agent A and cleaning agent B, ensuring that the two cleaning agents are mixed in the appropriate ratio. The switching mechanism 6 includes a connecting pipe B611. A connecting pipe A5 is fixedly connected to the outer wall of the mold body 1, and the connecting pipe B611 is threaded onto the outer wall of the connecting pipe A5, connecting the switching mechanism 6 to the mold body 1. The function of body 1 is to provide a channel for the delivery of coolant and cleaning agent. A coolant inlet 612 is fixedly connected to the top of connecting pipe B611, serving as the inlet for coolant to enter the circular cooling pipe 3. During the O-ring sealing process, coolant enters the cooling pipe through this inlet to achieve the cooling function. A cleaning agent A inlet 613 is fixedly connected to the left side of the outer wall of connecting pipe B611, and a cleaning agent B inlet 614 is fixedly connected to the right side of the outer wall of connecting pipe B611, used for injecting cleaning agents A and B respectively. When cleaning is required for the circular cooling pipe 3, the cleaning agent enters the cooling pipe through these two inlets. A rotating shaft 615 is fixedly connected to the inner wall of connecting pipe B611, serving as the connecting rod B619 and connecting rod... A616 provides a rotational support, allowing the sealing ball 618 to change position under its influence, thus sealing and opening different inlets. A connecting rod B619 is rotatably connected to the inner wall of the rotating shaft 615. By rotating the connecting rod B619, the position of the sealing ball 618 can be changed, thereby controlling the opening and closing of the coolant inlet 612, the detergent A inlet 613, and the detergent B inlet 614. A connecting rod A616 is fixedly connected to the outer wall of the rotating shaft 615, and the sealing ball 618 is slidably connected to its top end, serving to connect the rotating shaft 615 and the sealing ball 618. The sealing ball 618 is slidably connected to the top end of the connecting rod A616. A spring A617 is fixedly connected to the outer wall of the rotating shaft 615.

[0025] Reference Figures 2-4The top of spring A617 is fixedly connected to the outer wall of sealing ball 618. A toothed knob 6111 is slidably connected to the inner wall of connecting rod B619. A knob B6114 is fixedly connected to the outer wall of toothed knob 6111. Pressing down and rotating knob B6114 allows the toothed knob 6111 to engage and disengage with toothed ring 6113, thereby controlling the position of sealing ball 618. A spring B6112 is fixedly connected to the outer wall of connecting rod B619. When the pressed knob B6114 is released, the elastic force of spring B6112 causes the toothed knob 6111 to move upwards, engaging with the toothed ring 6113. Ring 6113 re-engages, limiting the toothed knob 6111. The top of spring B6112 is fixedly connected to the back of the toothed knob 6111. As a further description of the above technical solution: there are two sets of connecting rod A616, spring A617 and sealing ball 618. The two sets of connecting rod A616, spring A617 and sealing ball 618 are symmetrically arranged at the left and right ends of the rotating shaft 615. The symmetrical design makes the switching of coolant inlet 612 and cleaning agent inlet more stable and reliable, and can effectively seal and open multiple inlets at the same time.

[0026] Reference Figures 2-4The metering mechanism 7 includes a connecting rod C711, which is rotatably connected to the outer surface of the connecting tube B611, providing mounting and rotational support for the active turntable 714, enabling the active turntable 714 to drive the driven disc 716 to rotate. A limit rod 712 is fixedly connected to the outer surface of the connecting tube B611, cooperating with a bolt 713 to lock the position of the active turntable 714, preventing it from rotating arbitrarily during operation and ensuring metering accuracy. The active turntable 714 is inserted into the outer wall of the connecting rod C711. Rotating the active turntable 714 can drive the driven disc 716, which meshes with it, to rotate, thereby controlling the rotation of the connecting rod D715 and the ball 717, and realizing the control of the amount of cleaning agent injected. The connecting rod D715 is rotatably connected to the inner wall of the connecting tube B611, with the inner extension end connected to the ball 717 and the outer extension end connected to the driven disc 716, which plays the role of transmitting rotational power. The inner extension end of the connecting rod D715 is fixedly connected to a ball 717. By rotating the ball 717, the opening and closing angle of the cleaning agent inlet is changed, thereby precisely controlling the injection amount of cleaning agent A and cleaning agent B. The outer extension end of the connecting rod D715 is fixedly connected to the active turntable 714. The ball 717 rotates under the drive of the active turntable 714, thereby adjusting the injection amount of cleaning agent. A driven plate 716 is connected, and the outer wall of the active turntable 714 meshes with the outer wall of the driven plate 716. The inner wall of the connecting rod C711 is threaded with a bolt 713. By tightening the bolt 713, the active turntable 714 can be locked in a specific position to prevent it from rotating during operation. The extension end of the bolt 713 is threaded to the inner wall of the limiting rod 712. The outer walls of the circular cooling pipes 3 are all interconnected, ensuring that the coolant and cleaning agent can flow evenly throughout the circular cooling pipes 3, improving the cooling and cleaning effect.

[0027] Working principle: A switching mechanism 6 is set at the top of the mold body 1. When the O-ring rubber seal is reached, the operator pours coolant into the circular cooling pipe 3 through the coolant inlet 612 at the top of the connecting pipe B611. The cooling pipe is continuously filled and circulated by the circulation pipe 4, which removes the heat from the O-ring rubber seal. When the coolant inlet 612 is opened, the cleaning agent inlets 613 and 614 at both ends are fixed and blocked by the sealing plug ball 618. This is achieved by first pressing down the knob. When the knob is pressed down, it causes... The toothed knob 6111 moves downward, disengaging from the toothed ring 6113. This, in turn, rotates the connecting rod, causing the two sets of sealing balls 618 connected to the inner wall of the connecting rod to change position, sealing the coolant inlet 612 and either the detergent A inlet 613 or the detergent B inlet 614. After the sealing balls 618 are sealed, manually releasing the knob causes the toothed knob 6111 to re-engage with the toothed ring 6113 under the action of the spring B6112, thus ensuring that the toothed knob 6111 is limited to prevent loosening. Both inlet A (613) and inlet B are equipped with metering mechanisms (7). By mixing different cleaning agents at both ends, scale and impurities inside the circular cooling pipe (3) are cleaned. When metering is performed simultaneously at both ends, the active turntable (714) on the outer wall of connecting pipe B611 is rotated. When the active turntable (714) rotates, it drives the driven discs (716) meshing at both ends to rotate, thereby controlling the opening and closing angle of the ball (717) at the top of the connecting rod. This ensures that the dosage of cleaning agent A and cleaning agent B is equal, allowing the cleaning agent to be poured into the circular cooling pipe (3) through connecting pipe B611. In the cooling pipe 3, the threaded circulation pipe 4 is removed to allow the cleaned wastewater to be discharged directly. When the amount of cleaning agent A inlet 613 and cleaning agent B inlet 614 is not equal, the active turntable 714 is removed, and the driven plate 716 is rotated independently, which independently drives the opening and closing angle of the ball 717. Then, the active turntable 714 is inserted into the connecting rod, and the bolt 713 passes through the connecting rod and is threaded onto the limit rod 712 to ensure the locking of the active turntable 714 and prevent the driven plate 716 from rotating, thereby achieving the quantitative measurement of the cleaning agent.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
