Description

Technical Field

[0001] This utility model relates to the field of rubber product processing technology, specifically to an adaptive flow valve for rubber injection molding. Background Technology

[0002] In the field of rubber injection molding, flow valves are key components, and their performance directly affects the quality and efficiency of injection molding. With the continuous expansion of applications for rubber products, the requirements for injection molding precision and automation are becoming increasingly stringent. A new adaptive flow valve technology for rubber injection molding has emerged. Based on an innovative structural design, this technology achieves precise adaptive flow regulation through the collaborative work of multiple components, bringing a new breakthrough to the rubber injection molding process. Traditional flow valves often use fixed orifice diameters or adjusting knobs to control flow. However, due to the high viscosity and scorching characteristics of rubber materials, flow control becomes particularly difficult. Fixed orifice diameter flow valves cannot be flexibly adjusted according to material characteristics and production needs, while the precision of adjusting knobs is limited by manual operation, resulting in insufficient flow control. When producing rubber products of different specifications, it is necessary to replace flow valves with different orifice diameters or perform cumbersome adjustments, which not only increases production costs but also reduces production efficiency. Utility Model Content

[0028] Rubber injection molding adaptive flow valve, such as Figures 1-3As shown, the device includes an adaptive valve body 10 for rubber injection molding. A top seat 20 is mounted on the top of the adaptive valve body 10, and a hydraulic cylinder 30 is installed inside the top seat 20. A replaceable discharge head 40 is mounted on the bottom of the adaptive valve body 10. A material conveying channel 11 with a transverse T-shaped cross-section is provided inside the adaptive valve body 10. A check valve 12 is installed at the inlet end of the material conveying channel 11. The hydraulic rod 31 of the hydraulic cylinder 30 passes through the adaptive valve body 10 and is inserted into the material conveying channel 11. A piston 32 with a cross-sectional dimension adapted to the material conveying channel 11 is coaxially connected to the bottom end of the hydraulic rod 31. A guide rod 33 is coaxially mounted on the bottom of the piston 32, and the bottom of the guide rod 33 is coaxially connected to the replaceable discharge head. The sealing plug 34, with an inner diameter matching the rubber injection molding process, is connected to the self-adaptive valve body 10 for rubber injection molding. The top seat 20 mounted on the top of the valve body 10 cooperates with the internal hydraulic cylinder 30 to provide power to the hydraulic rod 31. The hydraulic rod 31 drives the piston 32 to move within the material conveying channel 11, which can control the flow rate. The check valve 12 at the feed end of the material conveying channel 11 prevents material backflow. The guide rod 33 ensures the stability of the movement of the sealing plug 34. The sealing plug 34 is compatible with the inner diameter of the replaceable discharge head 40, which can flexibly control the discharge. Different replaceable discharge heads 40 can meet diverse needs, thereby realizing the adaptive adjustment of the flow rate during the rubber injection molding process and improving the accuracy and efficiency of the injection.

[0029] Furthermore, the discharge end of the conveying channel 11 is equipped with an external threaded ring seat 13, and the top of the replaceable discharge head 40 is provided with a threaded groove 41 that is adapted to the size of the external threaded ring seat 13 and threadedly connected. Through the external threaded ring seat 13 and the threaded groove 41, the replaceable discharge head 40 can be conveniently and quickly threadedly connected to the discharge end of the conveying channel 11, which facilitates the replacement of the discharge head according to different glue injection requirements and improves the versatility and flexibility of the equipment.

[0030] The sealing plug 34 and the replaceable discharge head 40 both have inverted isosceles trapezoidal cross sections. The inverted isosceles trapezoidal structure of the sealing plug 34 and the replaceable discharge head 40 allows the sealing plug 34 to form a good sealing effect when inserted into the replaceable discharge head 40. At the same time, this structure is also conducive to the flow and control of materials.

[0031] It is worth noting that the maximum diameter of the sealing plug 34 is smaller than the inner diameter of the external threaded ring seat 13, making it easy to replace.

[0032] In addition, the bottom of the guide rod 33 is coaxially provided with a mounting screw hole 36, and the top of the sealing plug 34 is coaxially provided with a threaded connecting post 35 that is compatible with the size of the mounting screw hole 36 and is threadedly connected. Through the mounting screw hole 36 and the threaded connecting post 35, the sealing plug 34 can be firmly installed at the bottom of the guide rod 33, which facilitates the installation and removal of the sealing plug 34, as well as its maintenance and replacement.

[0033] The working principle of this rubber injection molded adaptive flow valve:

[0034] Before use, select the appropriate replaceable discharge head 40 and sealing plug 34 according to the specific glue injection process requirements; the sealing plug 34 is connected to the mounting screw hole 36 at the bottom of the guide rod 33 by the threaded connecting post 35 at the top to complete the assembly; then, the selected replaceable discharge head 40 is connected to the external threaded ring seat 13 at the discharge end of the material conveying channel 11 by the threaded groove 41 at the top and installed on the adaptive valve body 10.

[0035] Then, the material to be injected is injected from the feed end of the conveying channel 11. At this time, the check valve 12 will play a role to prevent the material from flowing back.

[0036] Then, the hydraulic cylinder 30 inside the top seat 20 is activated. The hydraulic cylinder 30 pushes the hydraulic rod 31 to move downward, which in turn drives the piston 32 to slide in the material conveying channel 11, pushing the material towards the replaceable discharge head 40. During this process, the guide rod 33 will ensure the stability of the movement.

[0037] When it is necessary to adjust the flow rate or stop the discharge, the hydraulic cylinder 30 is further controlled. The hydraulic rod 31 drives the piston 32 to continue to move, and the sealing plug 34 at the bottom of the guide rod 33 will gradually be inserted into the replaceable discharge head 40. Relying on its compatibility with the inverted isosceles trapezoidal structure of the replaceable discharge head 40, the discharge port is controlled, thereby adjusting the glue injection flow rate. After the glue injection work is completed, the hydraulic cylinder 30 is reversed to remove the sealing plug 34 from the replaceable discharge head 40 for the next use.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
