Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to an injection mold that is easy to clean. Background Technology

[0002] Injection molding, a common industrial product manufacturing method, is widely used in rubber and plastic injection molding, and can be divided into injection molding compression molding and die casting. In the injection molding process, the injection mold is an indispensable tool for producing plastic products, its function being to give the plastic products a complete structure and precise dimensions.

[0003] In existing technologies, the lower mold is usually fixed inside the machine casing. After injection molding, people often use an air gun to clean the lower mold, but this leaves debris inside the machine casing, greatly increasing the difficulty of cleaning. In addition, operators need to put their hands inside the machine casing, which poses certain safety hazards and causes a lot of inconvenience to users.

[0004] Existing patents (such as CN218615158U) use a screw drive to move the lower mold outside the machine casing for cleaning, thus improving safety. However, this method of setting up the lower track is prone to accumulating dust and debris during the use of the injection mold, leading to unstable track movement and affecting the normal operation of the equipment.

[0005] Therefore, those skilled in the art have provided an injection mold that is easy to clean in order to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an injection mold that is easy to clean. As the sliding mechanism moves outward, the gas ejected from the air outlet can blow away the upper part of the support base, blowing debris into the cleaning tank and smoothly discharging it from the support base, thus facilitating cleaning.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An easy-to-clean injection mold includes a support base, a stabilizing slide bar fixedly arranged between the two sides inside the support base, a sliding mechanism slidably arranged outside the two stabilizing slide bars, and a mold body arranged at the upper end inside the sliding mechanism;

[0009] Multiple lower connecting frames are fixedly installed at the front and rear positions of the lower end of the support base. Two air outlet mechanisms are fixedly installed at the lower ends of the multiple lower connecting frames. Each air outlet mechanism includes a sealing cylinder. A power piston is slidably installed inside the sealing cylinder. A connecting rope is fixedly installed on one side of the power piston. A spring is connected between the other side of the power piston and the sealing cylinder. A one-way valve is installed through one side of the sealing cylinder.

[0010] Furthermore, two pulleys are fixedly installed on one side of the support base near the front and rear positions, and the other ends of the two connecting ropes pass through the pulleys and the support base and are fixedly connected to one side of the sliding mechanism.

[0011] Furthermore, the sliding mechanism includes a sliding table, an air inlet pipe is provided through the front end of the sliding table, one end of the air inlet pipe is fixedly connected to the air outlet mechanism, two air outlets are provided through one side of the sliding table, and the other end of the air inlet pipe is fixedly connected to the two air outlets.

[0012] Furthermore, two stabilizing slide rails are fixedly installed at the upper end of the support base, and the sliding platform is slidably installed at the upper end of the two stabilizing slide rails.

[0013] Furthermore, a mold frame is fixedly installed on the upper end of the sliding platform, and multiple fixing bolts are threaded through the mold frame. The mold body is connected to the inside of the mold frame by multiple fixing bolts.

[0014] Furthermore, a motor frame is fixedly installed on one side of the support base, a motor body is fixedly installed on one side of the motor frame, a power screw is fixedly installed at the output end of the motor body, and the sliding table is threadedly sleeved on the outside of the power screw.

[0015] Furthermore, the support base has cleaning grooves on both the front and rear sides of the side away from the sliding mechanism.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model proposes an injection mold that is easy to clean. When the power screw drives the sliding mechanism to move, the sliding mechanism drives the power piston to slide inside the sealed cylinder via a connecting rope. The power piston compresses the gas inside the sealed cylinder, and the gas flows directly from the air inlet pipe to the air outlet and is ejected. As the sliding mechanism moves outward, the gas ejected from the air outlet can blow away the upper part of the support base, blowing debris into the cleaning tank and smoothly discharging it from the support base, greatly simplifying the cleaning process and significantly reducing the burden of cleaning work.

[0018] 2. The present invention proposes an injection mold that is easy to clean. The mold body is mounted on a movable sliding mechanism, which avoids the operator having to put their hands into the machine box for cleaning, effectively reducing safety risks. Attached Figure Description

[0025] 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.

[0026] Reference Figure 1-3 An embodiment of this utility model provides: an easy-to-clean injection mold, including a support base 8, a stabilizing slide rod 6 fixedly arranged between the two sides inside the support base 8, a sliding mechanism 3 slidably arranged outside the two stabilizing slide rods 6, a mold body 4 arranged at the upper end inside the sliding mechanism 3, a cleaning groove 11 is provided on the side of the support base 8 away from the sliding mechanism 3 near the front and rear positions, and multiple lower connecting frames 12 are fixedly arranged at the front and rear positions of the lower end of the support base 8, and two air outlet mechanisms 1 are fixedly arranged at the lower end of the multiple lower connecting frames 12.

[0027] Specifically, the stabilizing slide bar 6 provides a stable sliding guide for the sliding mechanism 3, enabling it to move smoothly within the support base 8. The cleaning trough 11 collects debris blown out from inside the support base 8 for easy centralized cleaning. The lower connecting frame 12 secures the air outlet mechanism 1, providing a mounting base for it. The stabilizing slide bar 6 ensures the stability of the sliding mechanism 3's movement, improving the overall reliability of the mold's operation. The cleaning trough 11's design facilitates debris discharge and subsequent cleaning, enhancing cleaning efficiency. The air outlet mechanism 1 is securely installed via the lower connecting frame 12, laying the foundation for subsequent gas-blowing cleaning of debris.

[0028] Reference Figure 4Both air outlet mechanisms 1 include a sealing cylinder 101. A power piston 103 is slidably arranged inside the sealing cylinder 101. A connecting rope 102 is fixedly arranged on one side of the power piston 103. A spring is connected between the other side of the power piston 103 and the sealing cylinder 101. A one-way valve 104 is arranged through one side of the sealing cylinder 101. Two pulleys 2 are fixedly arranged on one side of the support base 8 near the front and rear positions. The other ends of the two connecting ropes 102 pass through the pulleys 2 and the support base 8 and are fixedly connected to one side of the sliding mechanism 3.

[0029] Specifically, when the sliding mechanism 3 moves, the connecting rope 102 pulls the power piston 103 to slide inside the sealing cylinder 101. The power piston 103 compresses the gas inside the sealing cylinder 101, and the compressed gas is discharged from the air outlet 305 of the sealing cylinder 101 for cleaning. When the power piston 103 resets, the spring pulls the power piston 103 back to its initial position. At this time, the one-way valve 104 opens, and outside air enters the sealing cylinder 101 to prepare for the next compressed air. The pulley 2 changes the direction of force on the connecting rope 102, allowing the sliding mechanism 3 to drive the power piston 103 more smoothly. The movement of the sliding mechanism 3 drives the air outlet mechanism 1 to work, realizing the linkage between the cleaning function and the mold movement. No additional power source is required, making it energy-saving and efficient. The coordinated design of the spring and the one-way valve 104 ensures that the air outlet mechanism 1 can continuously and stably output compressed air for cleaning, improving the continuity of the cleaning effect. The pulley 2 reduces friction between the connecting rope 102 and the support base 8, extends the service life of the connecting rope 102, and makes power transmission smoother.

[0030] Reference Figure 2 The sliding mechanism 3 includes a sliding table 303. An air inlet pipe 302 is provided through the front end of the sliding table 303. One end of the air inlet pipe 302 is fixedly connected to the air outlet mechanism 1. Two air outlets 305 are provided through one side of the sliding table 303. The other end of the air inlet pipe 302 is fixedly connected to the two air outlets 305. Two stabilizing slide rails 5 are fixedly provided inside the upper part of the support base 8. The sliding table 303 is slidably provided on the upper part of the two stabilizing slide rails 5. A mold frame 304 is fixedly provided on the upper part of the sliding table 303. Multiple fixing bolts 301 are threaded through the mold frame 304. The mold body 4 is connected to the inside of the mold frame 304 by multiple fixing bolts 301.

[0031] Specifically, the stabilizing slide rail 5 provides precise guidance for the movement of the sliding table 303, ensuring the smoothness of its movement. Compressed air generated by the air outlet mechanism 1 enters the sliding table 303 through the air inlet pipe 302 and is ejected from two air outlets 305 on one side of the sliding table 303, cleaning the interior of the support base 8. The mold frame 304 is connected to the mold body 4 via fixing bolts 301, facilitating the installation and disassembly of the mold body 4. The stabilizing slide rail 5 and the stabilizing slide rod 6 work together to greatly improve the stability and precision of the sliding table 303's movement, helping to ensure the accuracy of the mold during operation. The design of the air inlet pipe 302 and air outlet 305 of the sliding table 303 allows compressed air to efficiently act on the areas inside the support base 8 that need cleaning, enhancing the cleaning effect. The mold frame 304 and fixing bolts 301 facilitate the replacement and maintenance of the mold body 4, improving the mold's versatility and maintainability.

[0032] Reference Figure 1-3 A motor frame 9 is fixedly installed on one side of the support base 8, a motor body 10 is fixedly installed on one side of the motor frame 9, a power screw 7 is fixedly installed at the output end of the motor body 10, and a sliding table 303 is threadedly sleeved on the outside of the power screw 7.

[0033] Specifically, after the motor body 10 starts, the power screw 7 at its output end rotates. Since the sliding table 303 is threaded onto the outside of the power screw 7, according to the principle of threaded transmission, the rotation of the power screw 7 is converted into linear movement of the sliding table 303 along the screw axis, thereby driving the sliding mechanism 3 and the mold body 4 to move. The motor frame 9 is used to fix the motor body 10, providing stable installation support for the motor body 10. The cooperation between the motor body 10 and the power screw 7 provides a stable and controllable power source for the movement of the sliding mechanism 3, enabling precise control of the moving speed and position of the sliding mechanism 3. The motor frame 9 ensures the stability of the motor body 10 installation, ensuring that the motor body 10 will not shift or shake during operation, thereby ensuring the stability and reliability of the entire mold system operation.

[0034] Working principle: After the motor body 10 starts, the power screw 7 at its output end begins to rotate. Since the sliding table 303 is threaded onto the outside of the power screw 7, the rotation of the power screw 7 drives the sliding table 303 to move along the stable slide rail 5, thereby moving the mold body 4 together. When the sliding table 303 moves, one side of the sliding table 303 is connected to the power piston 103 through the connecting rope 102. The movement of the sliding table 303 pulls the connecting rope 102, causing the power piston 103 to slide inside the sealing cylinder 101, thereby compressing the gas inside the sealing cylinder 101. At this time, the compressed gas flows directly from the air inlet pipe 302 to the air outlet 305 and is ejected at high speed, blowing the upper part of the support base 8, blowing the debris into the cleaning tank 11 and discharging it from the support base 8. When the power piston 103 resets, the spring pulls the power piston 103 back to its initial position. At this time, the one-way valve 104 opens, and outside air enters the sealing cylinder 101 to prepare for the next compressed air. This cycle continues to clean the environment around the injection mold, ensuring the normal operation of the mold and the convenience of subsequent operations.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
