[0002] Molds are an indispensable and important tool in the manufacturing industry and are widely used in many fields such as machinery, automobiles, electronics, and aviation. Their main function is to mold raw materials into parts of specified shapes and specifications through processes such as pressing, injection molding, and casting. Molds with convex molded shift fork parts are mainly used in automobile transmission systems to control the precise positioning and operation of shift forks. This type of mold requires high precision and good wear resistance to ensure that the finished parts can maintain their stable performance for a long time during actual use.

[0003] The existing mold uses the cooperation of the upper mold and the lower mold to punch the metal sheet into a fork part with a specific shape and convex structure under the action of the punching machine. In this mold design, the convex part plays a role in strengthening the strength of the part and increasing the contact area, effectively improving the durability and service life of the part. At the same time, the molding mold can ensure the consistency of each part, thereby ensuring the assembly quality and stable performance of the entire product.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 , Figure 3 and Figure 4 The utility model provides an embodiment: a mold for a convex fork part, comprising an upper mold base 1 and a lower mold base 6, the lower surface of the upper mold base 1 is fixedly connected with a middle plate 3, the interior of the middle plate 3 is fixedly connected with an upper clamping plate 5, the upper surface of the lower mold base 6 is provided with a concave mold plate 7, the lower surface of the concave mold plate 7 is slidably connected with a concave mold back plate 8, the lower surface of the concave mold back plate 8 is slidably connected with a lower pad 9, the upper surface of the lower mold base 6 is fixedly connected with a fixed plate 10, the outer wall of the fixed plate 10 is fixedly connected with an electric slide rail 11, the outer wall of the electric slide rail 11 is slidably connected with a slide seat 12, and the upper surfaces of the fixed plate 10 and the slide seat 12 are both fixedly connected with movable rings 13, The outer wall of the movable ring 13 is fixedly connected with a clamping pad 14, the outer walls of the fixed plate 10 and the sliding seat 12 are rotatably connected with a connecting frame 15, the outer wall of the movable ring 13 is fixedly connected with a sliding rod 16, the outer wall of the sliding rod 16 is slidably connected with a push plate 17, a limit spring 18 is arranged inside the movable ring 13, and a fixing component is arranged on the outer wall of the upper die seat 1, and the fixing component is used for connecting the upper die seat 1 and the lower die seat 6; the upper surface of the upper die seat 1 is fixedly connected with a fixed seat 2, and the lower surface of the upper die seat 1 is fixedly connected with a discharge plate 4, one end of the limit spring 18 is fixedly connected to the inside of the movable ring 13, and the other end of the limit spring 18 is fixedly connected to the outer wall of the push plate 17;

[0025] Specifically, when it is necessary to fix different cavity mold plates 7, the slide seat 12 is driven to slide by the electric slide rail 11, so that the slide seat 12 can approach the fixed plate 10. At the same time, the connecting frame 15 plays the role of connecting the fixed plate 10 and the slide seat 12. This process ensures that the clamping pads 14 on both sides can be evenly clamped on the surfaces of the cavity mold plate 7, the cavity back plate 8 and the lower pad 9. Subsequently, the limit spring 18 pushes the push plate 17 to slide along the outer wall of the slide rod 16, so that the push plate 17 can tightly clamp the cavity mold plate 7 again, which ensures the stable clamping of the cavity mold plate 7, the cavity back plate 8 and the lower pad 9, thereby ensuring the stability and safety during mold operation, which not only improves the practicability of the mold, enabling it to handle a variety of cavity mold plates 7, but also expands the scope of application of the mold, and improves production efficiency and operational safety.

[0026] Reference Figure 1-Figure 3The fixing assembly includes a mounting plate 22, the outer wall of which is slidably connected to the outer wall of the upper die base 1, and the outer wall of the mounting plate 22 is slidably connected to the outer wall of the lower die base 6; a support spring 19 is arranged inside the die back plate 8, one end of the support spring 19 is fixedly connected to the outer wall of the lower die base 6, and the other end of the support spring 19 is slidably connected to the outer wall of the die plate 7; a top piece 20 is fixedly connected to the outer wall of the lower die base 6, and the outer walls of the top piece 20 respectively penetrate into the inside of the die back plate 8 and the lower pad 9, and the top piece 20 The outer wall of the upper die base 1 is slidably connected to the inside of the concave die plate 7; a force transmission rod 21 is fixedly connected to the inside of the fixed seat 2, a piston air pump 23 is fixedly connected to the outer wall of the upper die base 1, and a shunt pipe 24 is fixedly connected to the output end of the piston air pump 23; an air delivery pipe 25 is fixedly connected to the outer wall of the shunt pipe 24, and an air outlet nozzle 26 is fixedly connected to one end of the air delivery pipe 25; a positioning rod 28 is fixedly connected to the lower surface of the upper die base 1, and a sleeve 27 is fixedly connected to the upper surface of the lower die base 6, and the outer wall of the positioning rod 28 is slidably connected to the inside of the sleeve 27;

[0027] Specifically, when it is necessary to achieve rapid demolding of the object, the piston air pump 23 is used to deliver air to the shunt pipe 24, and the shunt pipe 24 then transmits the airflow to each air supply pipe 25, and finally the airflow is sprayed onto the surface of the object through the air outlet nozzle 26. This process can not only clean the impurities on the surface of the object, but also effectively reduce the temperature of the object, which allows the object to be quickly cooled and demolded, and then the object is pushed out of the mold by using the ejector 20. The ejector 20 can safely eject the object from the mold after it is cooled, ensuring the smooth progress of the demolding process. At the same time, the sleeve 27 can slide in the positioning rod 28, and the mounting plate 22 ensures the firm connection between the upper mold base 1 and the lower mold base 6, which not only enhances the overall stability of the mold, but also extends the service life of the mold. The stable mold structure can withstand high-frequency use and rapid demolding operations, reducing wear and damage caused by frequent use.

[0028] Working principle: When it is necessary to fix different concave mold plates 7, the slide seat 12 is driven to slide by the electric slide rail 11, so that the slide seat 12 can continuously approach the fixed plate 10, and at the same time, the connecting frame 15 can connect the fixed plate 10 and the slide seat 12 until the clamping pads 14 on both sides are clamped on the surfaces of the concave mold plate 7, the concave mold back plate 8, and the lower pad 9, and then the limit spring 18 pushes the push plate 17 to slide on the outer wall of the slide rod 16, so that the push plate 17 can clamp and fix the concave mold plate 7 again, thereby achieving the effect of stably clamping the concave mold plate 7, the concave mold back plate 8 and the lower pad 9, thereby improving the practicality of the mold and expanding the scope of application of the mold. When the object needs to be demoulded quickly, air is blown into the shunt pipe 24 through the piston air pump 23, and then distributed to each air supply pipe 25 by the shunt pipe 24, so that the air outlet nozzle 26 can blow the air flow to the surface of the object. In this way, on the one hand, impurities on the surface of the object can be cleaned, and on the other hand, the object can be cooled. The object is then ejected by the ejector 20, so as to achieve the effect of quickly cooling and demoulding the object, and then the sleeve 27 slides inside the positioning rod 28. At the same time, the mounting plate 22 can connect the pressed upper mold base 1 with the lower mold base 6, so that the mold as a whole can be stabilized, the stability of the mold is improved, and the service life of the mold is extended.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
