[0001] The utility model relates to the technical field of power transmission of agricultural machinery, and more specifically, to a toothed V-belt mold for agricultural machinery. Background Technique
[0002] The toothed V-belt for agricultural machinery is used for power transmission of working components of agricultural machinery. Its production adopts the reverse forming method, and this method will use a cylindrical smooth mold for processing.
[0003] Manufacturing a product of the traditional reverse forming toothed V-belt for agricultural machinery requires a product smooth mold and a rubber sleeve mold. The toothed V-belt for agricultural machinery has the characteristics of fast replacement (the model is upgraded every 2 - 3 years, and the product size is adjusted annually), long product length (2000mm - 4800mm, and the limit can reach 7000mm), and small batch scale, resulting in a long mold processing cycle, high cost, and slow recovery of mold costs. This is also one of the important reasons for the low enthusiasm of belt manufacturers for new product development.
[0004] Although the device has many beneficial effects, there are still the following problems: during the use of the device, the mold has a single function. Making the rubber sleeve of the product requires a new mold, which is costly and inconvenient to use; secondly, during the use of the device, the rubber sleeve is prone to sticking to the mold and is not easy to demold, and improvement is needed. In view of this, we propose a toothed V-belt mold for agricultural machinery. Content of the Utility Model

[0027] Please refer to Figures 1-5 , the present utility model provides a technical solution:
[0028] A toothed V-belt mold for agricultural machinery, including a mold body 1. At the top of the inner circumferential wall of the mold body 1, an end cover 2 is fixedly installed. At the top of the end cover 2, a plurality of injection holes 3 are opened. At the top of the mold body 1, a heightening component 4 is fixedly installed. The heightening component 4 includes a metal ring 401. At the bottom of the metal ring 401, a convex ring 402 is fixedly installed. A ring groove 403 is opened at the top of the mold body 1. Four brackets 404 are fixedly installed on the inner circumferential wall of the metal ring 401. At the top of each of the four brackets 404, a first screw hole 405 is opened. At the top of the end cover 2, a plurality of second screw holes 406 are opened. A screw 407 is threadedly connected to the first screw hole 405, and the bottom of the screw 407 is threadedly connected to the second screw hole 406. A plurality of demolding components 5 are fixedly installed on the outer circumferential wall of the metal ring 401. In this utility model, products are processed through the mold body 1. Raw materials are injected through the injection holes 3 for easy processing. The ring groove 403 corresponds to the convex ring 402, facilitating the fixation of the metal ring 401. By screwing the screw 407 into the second screw hole 406, the connection between the metal ring 401 and the mold body 1 becomes more stable. The metal ring 401 facilitates the production of rubber sleeves.
[0029] Specifically, the demolding component 5 includes a groove 501 opened inside the outer circumferential wall of the metal ring 401. A moving rod 502 is slidably connected to the groove 501. A fixing ring 503 is fixedly installed on the outer circumferential wall of the moving rod 502. A spring 504 sleeved on the outer circumferential wall of the moving rod 502 is fixedly installed on the side wall of the fixing ring 503. The other end of the spring 504 is fixedly connected to the side wall of the groove 501. By manually pressing the moving rod 502 to drive the moving rod 502 to move inward, the rubber sleeve after processing is separated from the inner circumferential wall of the metal ring 401 to prevent adhesion. The fixing ring 503 is driven to move outward by the resilience of the spring 504, thus resetting the moving rod 502.
[0030] Furthermore, the diameter of the metal ring 401 is the same as that of the mold body 1, and the size and position of the convex ring 402 match the size and position of the ring groove 403. Through the convex ring 402 that matches the size and position of the ring groove 403, it is convenient to position the metal ring 401, making the connection between the mold body 1 and the metal ring 401 more convenient.
[0031] It should be noted that the size and position of the first screw hole 405 match the size and position of the second screw hole 406, and the screw 407 is a high-strength stainless steel socket head cap screw. Through the high-strength stainless steel socket head cap screw 407, the connection stability between the mold body 1 and the metal ring 401 is improved.
[0032] It should be noted that one end of the moving rod 502 extends beyond the outer circumferential wall of the metal ring 401, and the other end of the moving rod 502 is parallel to the inner circumferential wall of the metal ring 401. Through the moving rod 502 that extends beyond the outer circumferential wall of the metal ring 401, it is convenient for the staff to use and easy to press.
[0033] In addition, the mold body 1 is a cylindrical smooth mold, and multiple injection holes 3 are distributed in an annular array. The use of the cylindrical smooth mold body 1 improves the processing effect.
[0034] Working principle: When this device is used as a toothed V-belt mold for agricultural machinery, the product is processed through the mold body 1. The raw material is injected through the injection holes 3 for easy processing. The annular groove 403 corresponds to the convex ring 402, facilitating the fixation of the metal ring 401. By screwing the screw 407 into the second screw hole 406, the connection between the metal ring 401 and the mold body 1 becomes more stable. The metal ring 401 is used to make the rubber sleeve. By manually pressing the moving rod 502 to drive the moving rod 502 to move inward, the processed rubber sleeve is separated from the inner wall of the circumference of the metal ring 401 to prevent adhesion. The resilience of the spring 504 drives the fixed ring 503 to move outward, thus resetting the moving rod 502. The use of the high-strength stainless steel socket head cap screw 407 improves the stability of the connection between the mold body 1 and the metal ring 401. The use of the cylindrical smooth mold body 1 improves the processing effect.
