Description

Technical Field

[0001] This utility model relates to the field of treadmill plastic running belt processing technology, specifically to a processing mold for non-powered curved running plastic running belts. Background Technology

[0002] In industrial production, molds are various molds and tools used to obtain the desired products through injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. Molds are tools used to make shaped items. These tools are composed of various parts, and different molds are composed of different parts. They mainly achieve the processing of the shape of the item by changing the physical state of the material being molded. In the injection molding of plastic running belts for treadmills, a non-powered arc running plastic running belt processing mold is required.

[0003] Existing processing molds suffer from problems such as low molding accuracy, poor molding effect, low processing efficiency, and low yield. The sealing and buffering effect of existing processing molds is not good enough, which means that the molds cannot buffer the upper and lower mold bases when they are closed, and cannot achieve a better sealing effect between the upper and lower mold bases. In addition, the efficiency of demolding of existing processing molds is not high enough, which makes it inconvenient for users to eject the molded mold from the surface of the lower mold core, thus reducing the demolding efficiency of the processing molds. Utility Model Content

[0004] The purpose of this invention is to provide a non-powered arc running plastic running belt processing mold to solve the problems mentioned in the background art, such as insufficient sealing and buffering effect when using the processing mold and insufficient efficiency during demolding.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-powered arc running plastic running belt processing mold, including an upper template, an upper mold frame provided on the surface of the upper template, a lower template provided on one side of the upper template, a fixing plate installed on the surface of the lower template by screws, a lower mold frame installed on the surface of the fixing plate, the surfaces of the upper mold frame and the lower mold frame in contact, an upper mold core installed inside the upper mold frame by screws, a lower mold core installed inside the lower mold frame by screws, the inner wall of the upper mold core in contact with the inner wall of the lower mold core, mold cavities formed on the inner walls of the upper mold core and the lower mold core, a sealing and buffering mechanism provided on the surfaces of the upper mold frame and the lower mold frame, and a mechanism for easy demolding provided on the surface of the lower template.

[0006] Preferably, the surface of the upper mold plate is threaded with hexagon socket screws, one end of which penetrates the upper mold plate and is threadedly fastened to the surface of the upper mold frame. The inner wall of the lower mold core is equipped with cooling water pipes. A nozzle is installed on the surface at the center of the upper mold frame, one end of which extends to the outside of the upper mold plate and penetrates the upper mold core, communicating with the interior of the lower mold core. The inner wall of the upper mold plate is equipped with limit posts, one end of which penetrates the upper mold frame and extends to the outside of the upper mold frame. The surface of the lower mold frame is equipped with support posts, one end of which extends into the interior of the limit posts.

[0007] Preferably, the easy demolding mechanism consists of a mounting base, an ejector plate, a telescopic spring, a round ejector pin, and a guide rod. The mounting base is installed on the surface of the lower mold frame, and the surface of the mounting base is fixed to the surface of the lower mold plate. The surface of the lower mold plate is provided with an ejector plate, and the ejector plate slides against the inner wall of the fixed plate. Round ejector pins for ejecting material are installed on the surface of the top position of the ejector plate, and one end of the round ejector pin penetrates the lower mold core and extends into the interior of the lower mold core.

[0008] Preferably, a guide rod is installed on the surface of the top position of the lower mold plate. The top end of the guide rod is fixed to the surface of the bottom position of the upper mold frame. The telescopic spring slides in cooperation with the inner wall of the ejector plate. The surface of the guide rod is fitted with a telescopic spring. The surface of the bottom position of the telescopic spring is fixed to the surface of the ejector plate. The surface of the top position of the telescopic spring is fixed to the surface of the bottom position of the lower mold core.

[0009] Preferably, the sealing and buffering mechanism consists of a first rubber sealing gasket, a buffer groove, a shock absorber, and a second rubber sealing gasket. The surface of the lower mold frame is equipped with the first rubber sealing gasket, and the surface of the upper mold frame at the bottom position is provided with a buffer groove. The buffer groove is provided with a second rubber sealing gasket for sealing and shock absorption between the upper mold frame and the lower mold frame. The second rubber sealing gasket slides in contact with the inner wall of the buffer groove.

[0010] Preferably, the inner wall of the buffer groove is equipped with equally spaced shock absorbers, one end of which is fixed to the surface of the second rubber sealing gasket, and the second rubber sealing gasket is in contact with the surface of the first rubber sealing gasket.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the non-powered arc running plastic running belt processing mold not only enables the upper mold frame and the lower mold frame to be buffered when the mold is closed, but also achieves a better sealing effect between the upper mold frame and the lower mold frame. In addition, it makes it easier for the user to push the mold after injection from the surface of the lower mold core, making the demolding efficiency of the processing mold higher when in use.

[0012] 1. By setting a sealing and buffering mechanism, the second rubber sealing pad is driven to contact the surface of the first rubber sealing pad under the elastic force of the shock absorber inside the buffer groove. At this time, the first rubber sealing pad squeezes the second rubber sealing pad, causing the second rubber sealing pad to move into the buffer groove. The second rubber sealing pad squeezes the shock absorber, and the shock absorber relieves the pressure on the second rubber sealing pad. At the same time, the surfaces of the second rubber sealing pad and the first rubber sealing pad come into contact. Under the combined action of the first rubber sealing pad and the second rubber sealing pad, a sealing treatment is performed between the upper mold frame and the lower mold frame, making the plastic running belt injection more efficient. It realizes the sealing and buffering function of the processing mold, so that the processing mold can buffer when the upper mold frame and the lower mold frame are closed. At the same time, it can achieve a better sealing effect between the upper mold frame and the lower mold frame.

[0013] 2. By incorporating a convenient demolding mechanism, the injection molding machine's push rod presses against the ejector plate, causing the ejector plate to push the round ejector pin upwards. As the ejector plate moves upwards, it slides on the surface of the guide rod, which guides the ejector plate. At this time, the telescopic spring contracts, allowing the round ejector pin to smoothly enter the lower mold core. Under the action of the round ejector pin, the injected plastic strip inside the lower mold core is ejected, achieving demolding. After demolding, the injection molding machine's push rod resets the ejector plate, and the telescopic spring's elasticity resets the ejector plate and round ejector pin, facilitating the next demolding. This design enables convenient demolding of the mold, making it easier for users to eject the injected mold from the surface of the lower mold core, resulting in higher demolding efficiency during mold use.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] The structure of the non-powered curved running belt processing mold provided by this utility model is as follows: Figures 1 to 5 As shown, the system includes an upper template 1, with an upper mold frame 103 mounted on its surface. All surfaces of the upper template 1 are threaded with hexagonal socket head cap screws 102, one end of which penetrates the upper template 1 and is threadedly fastened to the surface of the upper mold frame 103. A lower template 106 is mounted on one side of the upper template 1. A fixing plate 105 is mounted on the surface of the lower template 106 by screws. A lower mold frame 104 is mounted on the surface of the fixing plate 105. The surfaces of the upper mold frame 103 and the lower mold frame 104 are in contact. An upper mold core 107 is mounted inside the upper mold frame 103 by screws, and a lower mold core 108 is mounted inside the lower mold frame 104 by screws. The upper mold core 107 and the lower mold core 108... The inner walls of molds 107 and 108 are in contact with each other. Mold cavities are formed on the inner walls of the upper mold core 107 and the lower mold core 108. Cooling water pipes 109 are installed on the inner walls of the lower mold core 108. A nozzle 101 is installed on the surface at the center of the upper mold base 103. One end of the nozzle 101 extends to the outside of the upper mold plate 1. The other end of the nozzle 101 passes through the upper mold core 107 and communicates with the interior of the lower mold core 108. Limiting posts 110 are installed on the inner walls of the upper mold plate 1. One end of the limiting post 110 passes through the upper mold base 103 and extends to the outside of the upper mold base 103. Support posts 111 are installed on the surface of the lower mold base 104. One end of the support post 111 extends into the interior of the limiting post 110.

[0024] Furthermore, such as Figure 6 and Figure 7As shown, the surfaces of the upper mold frame 103 and the lower mold frame 104 are provided with a sealing and buffering mechanism 3. The sealing and buffering mechanism 3 consists of a first rubber sealing gasket 31, a buffer groove 32, a shock absorber 33, and a second rubber sealing gasket 34. The surface of the lower mold frame 104 is equipped with the first rubber sealing gasket 31. The surface of the upper mold frame 103 at the bottom position is provided with a buffer groove 32. The interior of the buffer groove 32 is provided with a second rubber sealing gasket 34 for sealing and shock absorption between the upper mold frame 103 and the lower mold frame 104. The second rubber sealing gasket 34 slides and engages with the inner wall of the buffer groove 32. The inner wall of the buffer groove 32 is equipped with equally spaced shock absorbers 33. One end of the shock absorber 33 is fixed to the surface of the second rubber sealing gasket 34. The second rubber sealing gasket 34 is in contact with the surface of the first rubber sealing gasket 31.

[0025] During implementation, under the elastic force of the shock absorber 33 inside the buffer groove 32, the second rubber sealing gasket 34 moves to contact the surface of the first rubber sealing gasket 31. At this time, the first rubber sealing gasket 31 squeezes the second rubber sealing gasket 34, causing the second rubber sealing gasket 34 to move into the buffer groove 32. The second rubber sealing gasket 34 squeezes the shock absorber 33, and under the action of the shock absorber 33, the extrusion force on the second rubber sealing gasket 34 is relieved and buffered. At the same time, the second rubber sealing gasket 34 contacts the surface of the first rubber sealing gasket 31. Under the combined action of the first rubber sealing gasket 31 and the second rubber sealing gasket 34, a sealing treatment is performed between the upper mold frame 103 and the lower mold frame 104, making the injection molding of the plastic running belt more efficient, so as to realize the function of sealing and buffering the processing mold.

[0026] Furthermore, such as Figure 3 and Figure 4 As shown, the surface of the lower mold plate 106 is provided with a demolding mechanism 2, which consists of a mounting base 21, an ejector plate 22, a telescopic spring 23, a round ejector pin 24, and a guide rod 25. The mounting base 21 is mounted on the surface of the lower mold frame 104, and the surface of the mounting base 21 is fixed to the surface of the lower mold plate 106. The surface of the lower mold plate 106 is provided with an ejector plate 22, which slides against the inner wall of the fixing plate 105. Round ejector pins 24 for ejecting material are mounted on the top of the ejector plate 22. One end of 4 passes through the lower mold core 108 and extends into the interior of the lower mold core 108. Guide rods 25 are installed on the surface of the top position of the lower mold plate 106. The top end of the guide rod 25 is fixed to the surface of the bottom position of the upper mold frame 103. The telescopic spring 23 slides and engages with the inner wall of the ejector plate 22. The surface of the guide rod 25 is fitted with the telescopic spring 23. The surface of the bottom position of the telescopic spring 23 is fixed to the surface of the ejector plate 22. The surface of the top position of the telescopic spring 23 is fixed to the surface of the bottom position of the lower mold core 108.

[0027] During implementation, the ejector rod of the injection molding machine presses against the ejector plate 22, causing the ejector plate 22 to drive the round ejector pin 24 upward. When the ejector plate 22 moves upward, it slides on the surface of the guide rod 25. Under the action of the guide rod 25, the ejector plate 22 is guided. At this time, the telescopic spring 23 contracts, allowing the round ejector pin 24 to smoothly enter the interior of the lower mold core 108. Under the action of the round ejector pin 24, the plastic strip after injection into the lower mold core 108 is ejected, realizing demolding. After demolding is completed, the ejector rod of the injection molding machine drives the ejector plate 22 to reset. Under the elastic force of the telescopic spring 23, the ejector plate 22 and the round ejector pin 24 are reset, facilitating the next demolding, thus realizing the function of convenient demolding of the processed mold.

[0028] Working principle: In use, the upper mold base 103 and the lower mold base 104 are first positioned and assembled under the combined action of the limiting column 110 and the support column 111. Then, the internal hex screws 102 are tightened to assemble the upper mold plate 1 and the upper mold base 103. After the upper mold plate 1 is assembled, it is installed on the injection molding machine for use. Plastic granules enter the injection molding machine through the hopper. The plastic granules are pushed forward with the rotation of the screw. During the forward movement, the plastic is melted into a plastic fluid by the heating device. The screw continues to push forward, quickly squeezing the plastic fluid into the lower mold core 108 through the nozzle 101 until the plastic... Fluid fills the entire mold cavity of the lower mold core 108. Then, cold water is added into the cooling water pipe 109. When the cold water circulation is started, it can remove the heat inside the lower mold core 108 and the upper mold core 107, accelerating the cooling of the product inside the upper mold core 107 and the lower mold core 108. After the product cools and solidifies, it is injection molded into a plastic running belt. Then, the upper mold plate 1 moves the upper mold base 103 and the upper mold core 107 away from the surface of the lower mold core 108 and the lower mold base 104. At this time, the upper mold core 107 moves away from the surface of the lower mold core 108, and the upper mold plate 1 moves the limiting post 110 away from the surface of the support post 111 on the surface of the lower mold base 104, thus realizing mold opening.

[0029] Subsequently, when the upper mold frame 103 and the lower mold frame 104 are closing, the second rubber sealing gasket 34 moves to contact the surface of the first rubber sealing gasket 31 under the elastic force of the shock absorber 33 inside the buffer groove 32. At this time, the first rubber sealing gasket 31 squeezes the second rubber sealing gasket 34, causing the second rubber sealing gasket 34 to move into the buffer groove 32. The second rubber sealing gasket 34 squeezes the shock absorber 33, and the shock absorber 33 relieves and buffers the compressive force on the second rubber sealing gasket 34. The second rubber sealing gasket 34 contacts the surface of the first rubber sealing gasket 31. Under the combined action of the first rubber sealing gasket 31 and the second rubber sealing gasket 34, a sealing treatment is performed between the upper mold frame 103 and the lower mold frame 104, making the plastic running belt injection more efficient and realizing the sealing and buffering function of the processing mold. This allows the processing mold to buffer the upper mold frame 103 and the lower mold frame 104 when they are closed, and at the same time, it can achieve a better sealing effect between the upper mold frame 103 and the lower mold frame 104.

[0030] Subsequently, the ejector rod of the injection molding machine (not shown in the figure) presses against the ejector plate 22, causing the ejector plate 22 to drive the round ejector pin 24 upward. When the ejector plate 22 moves upward, it slides on the surface of the guide rod 25. Under the action of the guide rod 25, the ejector plate 22 is guided. At this time, the telescopic spring 23 contracts, allowing the round ejector pin 24 to smoothly enter the interior of the lower mold core 108. Under the action of the round ejector pin 24, the plastic strip after injection is ejected from the interior of the lower mold core 108, realizing demolding. After demolding is completed, the ejector rod of the injection molding machine drives the ejector plate 22 to reset. Under the elastic force of the telescopic spring 23, the ejector plate 22 and the round ejector pin 24 are reset, facilitating the next demolding. This realizes the function of convenient demolding of the processing mold, making it easier for the user to eject the molded mold from the surface of the lower mold core 108 during use. This makes the demolding efficiency of the processing mold higher, and finally completes the use of the processing mold.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
