[0027] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0028] like Figures 1-5 As shown, a quick-change mechanism for wear-resistant plastic molds includes a frame 1, an upper mounting base 2 is provided inside the frame 1, and the bottom of the upper mounting base 2 abuts against the lower mounting base 4 through the mold body 3;

[0029] The top of the lower mounting base 4 is provided with a sliding groove 5, and a clamping mechanism 7 is slidably installed inside the sliding groove 5. A positioning mechanism 8 is provided inside the lower mounting base 4.

[0030] The clamping mechanism 7 includes a fixed base 71 and a piston head 74. The fixed base 71 has a cavity 73 inside that communicates with a compressed air connector 76. A push rod 75 is fixedly installed on the top of the piston head 74. The top of the push rod 75 pushes the clamping block 72 to swing.

[0031] See attached document Figure 1 and Figure 2 In this embodiment, the upper mounting base 2 is slidably installed with the frame 1, the lower mounting base 4 is fixedly installed with the frame 1, the upper mold of the mold body 3 is fixedly installed with the upper mounting base 2, and the lower mold of the mold body 3 is fixedly installed with the lower mounting base 4.

[0032] In the above embodiment, a drive device is installed on the top of the frame 1 to drive the upper mold of the mold body 3 to move vertically inside the frame 1. A support frame is provided at the bottom of the lower mounting base 4 inside the frame 1 so that the lower mold of the mold body 3 can be installed with the frame 1.

[0033] Furthermore, the upper mold of the mold body 3 is fixedly installed with the mold base 6 installed at the bottom of the upper mounting base 2, while the lower mold of the mold body 3 is fixedly installed with the mold base 6 at the top of the lower mounting base 4.

[0034] It should be noted that the upper mounting base 2 and the lower mounting base 4 can adopt the same structure, which is intended to enable the upper mold and the lower mold of the mold body 3 to be easily disassembled.

[0035] See attached document Figure 2 , Figure 4 and Figure 5 In this embodiment, the positioning mechanism 8 pushes the fixed seat 71 to move inside the slide groove 5, so that the fixed seat 71 abuts against the mold base 6, and the top of the fixed seat 71 is rotatably mounted with a clamping block 72.

[0036] In the above embodiment, the positioning mechanism 8 can push the fixed seat 71 to move on the surface of the lower mounting seat 4. There are four sets of fixed seats 71, which are distributed in pairs on both sides of the lower mounting seat 4. Therefore, the mold base 6 can be clamped and fixed by moving the fixed seat 71.

[0037] The fixed base 71 is equipped with a compressed air connector 76 on one side. The compressed air connector 76 is used to deliver compressed air into the cavity 73. When the compressed air enters the cavity 73, it can push the piston head 74 to drive the push rod 75 to move vertically, so that the top of the push rod 75 abuts against the clamping block 72, and pushes the other end of the clamping block 72 to move down and abut against the top of the mold base 6, thereby fixing the mold base 6.

[0038] Specifically, the push rod 75 is slidably installed with the fixed seat 71, while the piston head 74 is slidably installed with the cavity 73. A sealing ring is installed on the side of the piston head 74 to prevent compressed air from overflowing and affecting the fixing effect of the clamping block 72 on the mold base 6.

[0039] See attached document Figure 3 and Figure 5 In this embodiment, the positioning mechanism 8 includes a side plate 81 and a sliding seat 84. A motor 82 is fixedly installed on one side of the side plate 81, and the motor 82 drives the lead screw 83 to rotate. A hydraulic cylinder 85 is fixedly installed on the top of the sliding seat 84.

[0040] According to the above structure, the side plate 81 is fixedly installed inside the lower mounting base 4, and the sliding base 84 is threadedly installed with the motor 82. The hydraulic cylinder 85 is fixedly installed on the top of the sliding base 84. Therefore, when the motor 82 is started, it can drive the lead screw 83 to rotate. The rotation of the lead screw 83 can drive the sliding base 84 to move linearly, thereby causing the sliding base 84 to drive the hydraulic cylinder 85 to move linearly. Since the output shaft of the hydraulic cylinder 85 is telescopic, the clamping mechanism 7 can be pushed to move through the hydraulic cylinder 85.

[0041] It is worth noting that the output shaft of the hydraulic cylinder 85 is slidably mounted on the lower mounting base 4, and the hydraulic cylinder 85 can drive its output shaft to retract into the interior of the lower mounting base 4. Therefore, the limit on the clamping mechanism 7 can be released, allowing the clamping mechanism 7 to slide and disassemble from the interior of the slide groove 5.

[0042] The working principle of this utility model is as follows: When it is necessary to disassemble the mold body 3, simply disconnect the air supply pipe from the compressed air connector 76 to allow the air inside the cavity 73 to be discharged, causing the piston head 74 to drive the push rod 75 to fall, thereby releasing the support on one end of the clamping block 72, and the other end of the clamping block 72 to separate from the top of the mold base 6. At this time, by starting the hydraulic cylinder 85 to retract, the limit on the clamping mechanism 7 is released, and the two sets of clamping mechanisms 7 on one side inside the slide groove 5 can be directly disassembled. By starting the positioning mechanism 8, the clamping mechanisms 7 on the other two sides are pushed to move, thereby pushing the clamping mechanism 7 to slide on the top of the lower mounting base 4, so that the clamping mechanism 7 pushes the mold base 6 and the mold body 3 to move, thereby realizing the convenient disassembly of the mold body 3.

[0043] When it is necessary to install the mold body 3, simply align the slider at the bottom of the mold base 6 with the clamping mechanism 7 and slide it onto the top of the lower mounting base 4. Then, insert the clamping mechanism 7 into the slide groove 5 and simultaneously activate the hydraulic cylinder 85 to extend its output shaft into the slide groove 5. By starting the motor 82, the lead screw 83 rotates, causing the sliding base 84 to drive the hydraulic cylinder 85 to move linearly. This, in turn, drives the clamping mechanism 7 to move synchronously, positioning the mold base 6 and the mold body 3 at the predetermined position on the top of the lower mounting base 4. Then, connect the air supply pipe to the compressed air connector 76. By filling in compressed air, the gas pushes the piston head 74 to move the push rod 75 upward, and pushes one end of the clamping block 72 upward, while the other end of the clamping block 72 moves downward simultaneously and abuts against the top of the mold base 6, thereby fixing the mold base 6 and the mold body 3.

[0044] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
