[0001] This utility model relates to the technical field of mold processing equipment, and more specifically to an automatic high-frequency quenching device for the side mold of a casting wheel hub mold. Background technology:

[0002] The side mold of a cast wheel hub is basically composed of four side molds combined into one unit. The contact area between each two adjacent side molds is a 45-degree inclined surface. This inclined surface is also a parting area of ​​the wheel hub mold. This parting area is a wear-prone parting area. After a certain number of products are produced, this area is easily corroded by aluminum adhesion after wear, which will produce flash, affecting casting and machining efficiency. In severe cases, aluminum run-out may occur. Utility model content:

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic high-frequency quenching device for the side mold of a casting wheel hub mold. It can perform high-frequency quenching on the surface to be processed of the side mold of the wheel hub mold, thereby improving its hardness and service life.

[0004] The solution of this utility model to the aforementioned technical problem is:

[0005] An automatic high-frequency quenching device for casting wheel hub mold edge modules includes a main water receiving tank and a high-frequency quenching head extending from one side wall of the main water receiving tank. A push cylinder is fixed on the left side wall of the left side plate of the main water receiving tank. The right end of the push rod of the push cylinder extends out from the right side wall of the left side plate of the main water receiving tank and is fixed with a placement trolley. The wheel hub mold edge module to be processed is placed on the placement trolley. The surface of the wheel hub mold edge module to be processed is close to and corresponds to the bottom surface of the high-frequency quenching head.

[0006] Furthermore, the top surface of the bottom plate of the main water receiving tank is fixed with corresponding left and right extending transverse guide rails, and the bottom of the trolley is fixed with trolley wheels, which are placed on the corresponding transverse guide rails.

[0016] Figure 2 This is a partial structural schematic diagram of the present invention in a side view. Detailed implementation method:

[0017] For example, see below. Figures 1 to 2 As shown, an automatic high-frequency quenching device for the side mold of a casting wheel hub mold includes a main water receiving tank 10, a high-frequency quenching head 20 extending from one side wall of the main water receiving tank 10, and a water spray pipe 2, with the water spray pipe 2 located on one side of the high-frequency quenching head 20.

[0018] A hydraulic cylinder 30 is fixed to the left side wall of the left side plate of the main water receiving tank 10. The right end of the push rod of the hydraulic cylinder 30 extends out of the right side wall of the left side plate of the main water receiving tank 10 and is fixed thereon with a placement trolley 40. The wheel hub mold side module 100 to be processed is placed on the placement trolley 40. The surface to be processed of the wheel hub mold side module 100 is close to and corresponds to the bottom surface of the high-frequency quenching head 20. The outlet of the water spray pipe 2 corresponds to the surface to be processed of the wheel hub mold side module 100. A drain pipe can also be connected to the lower part of one side plate of the main water receiving tank 10 to facilitate the drainage of water from the main water receiving tank 10 for recycling.

[0019] The surface to be processed of the wheel hub mold side module 100 is the front side wall of the front part or the rear side wall of the rear part of its arc-shaped top surface. At this time, it is placed vertically and leans against the surface to be processed when the trolley 40 is placed. This surface to be processed is the inclined surface at a 45° angle where two adjacent wheel hub mold side modules 100 are placed horizontally when the wheel hub mold side module 100 is used.

[0020] Furthermore, the top surface of the bottom plate of the main water receiving tank 10 is fixed with corresponding left and right extending transverse guide rails 1, and the bottom of the trolley 40 is fixed with push wheel 41, which is placed on the corresponding transverse guide rail 1.

[0021] Furthermore, the trolley 40 includes a trolley base frame 42, a rear support frame 43 is fixed to the rear of the top surface of the trolley base frame 42, the upper part of the front wall of the top transverse beam of the rear support frame 43 is formed with an obliquely extending oblique wall, a front support frame 44 is fixed to the front of the top surface of the trolley base frame 42, the rear top surface of the top transverse beam of the front support frame 44 is an oblique wall, and the top of the front support frame 44 is lower than the top of the rear support frame 43.

[0022] The front wall of the wheel hub mold side module 100 to be processed presses against the inclined wall of the front support frame 44, and the rear part of the bottom surface of the wheel hub mold side module 100 presses against the inclined wall of the rear support frame 43. The top surface of the trolley base frame 42 is fixed with a middle transverse support block 45, which is located behind the front support frame 44. The top surface of the middle transverse support block 45 is formed with a V-shaped elongated groove 46. The bottom end of the front part of the wheel hub mold side module 100 is inserted into the elongated groove 46. The lower part of the front wall of the wheel hub mold side module 100 presses against the front inner wall of the elongated groove 46, and the front part of the bottom surface of the wheel hub mold side module 100 presses against the rear inner wall of the elongated groove 46.

[0023] The accurate placement and positioning of the wheel hub mold side module 100 is ensured by pressing and positioning the inclined wall surface of the front support frame 44, the inclined wall surface of the rear support frame 43, and the front inner wall and rear inner wall of the elongated groove 46 of the middle transverse support block 45 against the wheel hub mold side module 100.

[0024] Furthermore, connecting blocks are fixed at the front and rear left and right parts of the bottom surface of the trolley base 42. Each connecting block 47 is movably connected to a push wheel 41 via a bearing. The top surface of the push wheel 41 presses against the top surface of the corresponding transverse guide rail 1. Radial extension edges 411 are formed on the outer side walls of the opposite ends of the front and rear push wheels 41. The outer side walls of the radial extension edges 411 are close to the inner side walls of the corresponding transverse guide rail 1.

[0025] In this embodiment, the high-frequency quenching head 20 is a component installed on the high-frequency quenching machine. Both the high-frequency quenching machine and the high-frequency quenching head 20 are conventional structures. The high-frequency quenching machine will not be described in detail here. The high-frequency quenching machine is located at the rear of the wall, and the high-frequency quenching head 20 extends out of the front wall surface. Similarly, the push cylinder 30 is also connected to the hydraulic system (which includes a hydraulic oil tank, oil pump, solenoid valve, etc., which are connected by a connecting pipe and are a conventional structure, and will not be described in detail here) through a connecting pipe.

[0026] In use, the wheel hub mold edge module 100 to be processed is placed on the placement trolley 40. By pushing the push rod of the hydraulic cylinder 30, the placement trolley 40 is moved to the right. During the movement, the wheel hub mold edge module 100 is moved to the right, so that the surface of the wheel hub mold edge module 100 to be processed is close to the bottom surface of the high-frequency quenching head 20 and moves horizontally. The high-frequency quenching head 20 performs high-frequency quenching on the corresponding part of the surface to be processed directly below it, so that its surface temperature rises instantly to 800-1000 degrees Celsius or above. Then, after this part passes through the high-frequency quenching head 20, it is simultaneously rapidly cooled by the water sprayed from the outlet of the water spray pipe 2 on the right side (which is connected to the water outlet of the water pump installed on the water storage tank through a connecting pipe. The water can be sprayed by opening the control valve. It is a conventional structure and will not be described in detail here). This allows the hardened edge mold to reach the ideal hardness.

[0027] The sprayed cooling water eventually accumulates in the main water receiving tank 10 and is discharged through the drain pipe.

[0028] This embodiment can perform high-frequency quenching on the surface to be machined of the wheel hub mold edge module 100, thereby improving its hardness and service life, reducing the frequency of later maintenance and repair, and improving casting and machining efficiency.
