Description

Technical Field

[0001] This utility model relates to the field of die casting technology for metal parts, specifically a die casting device for the production of metal furnace parts. Background Technology

[0002] Metal furnace components play a vital role in industrial production, as their quality and precision directly affect the performance and lifespan of the furnace. Die casting, a common method for producing metal furnace components, involves rapidly injecting molten metal into a mold cavity under high pressure, allowing the metal to cool and solidify to form components with specific shapes and dimensions.

[0003] According to the Chinese patent publication number "CN219881277U", a combined metal parts die-casting mold includes: a mold body, including a first module, a positioning rod connected to the top surface of the first module, and a second module sleeved on the outer wall of the top of the positioning rod; and limiting structures connected to both sides of the first module, including a first limiting plate, and a second limiting plate inserted inside the first limiting plate. This invention utilizes a second module that, when pressed down, drives a second limiting plate downwards. This causes the bottom end of the second limiting plate to compress the first spring rod, causing it to contract. A bearing seat connected to one side of the second limiting plate drives a gear to rotate within a groove in the first limiting plate, allowing the gear to move relative to the second limiting plate within the groove. This, in conjunction with the first limiting plate, limits the movement of the second limiting plate, thus preventing the mold from shifting position during die casting. However, during die casting, the mold is frequently subjected to thermal shock from the high-temperature molten metal and corrosion from the chemical components it may contain. Furthermore, the mechanical friction during demolding can cause significant damage to the mold, leading to premature wear, deformation, and corrosion. Therefore, this invention proposes a die casting device for the production of metal furnace accessories to address these problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a die-casting device for the production of metal furnace accessories, including a support base, on which a demolding mechanism is provided. The demolding mechanism includes a support frame, a storage tank, a delivery pump, a connecting hose, a cleaning nozzle, a threaded sleeve, and a screw. The storage tank is fixedly installed on the top of the support frame, the delivery pump is fixedly installed on one side of the storage tank, one end of the connecting hose is fixedly connected to the delivery pump, the cleaning nozzle is fixedly connected to the other end of the connecting hose, the threaded sleeve is rotatably connected to the top of the support frame through a bearing, the top end of the screw is threadedly connected to the inner wall of the threaded sleeve, and the bottom end of the screw is fixedly connected to the top of the cleaning nozzle.

[0006] Preferably, the demolding mechanism further includes a limiting lifting rod, which is fixedly installed on the support frame, and the bottom end of the inner rod of the limiting lifting rod is fixedly connected to the cleaning nozzle. With this preferred embodiment, the limiting lifting rod can limit the movement of the screw.

[0007] Preferably, the demolding mechanism further includes a motor and a helical gear set. The motor is fixedly mounted on the top of the support frame, one helical gear in the helical gear set is fixedly sleeved on the outer wall of one end of the motor output shaft, and the other helical gear in the helical gear set is fixedly sleeved on the outer wall of the threaded sleeve. With this preferred embodiment, by starting the motor, the motor output shaft drives the helical gear set fixedly sleeved on one end of the outer wall to rotate.

[0008] Preferably, the support base is further provided with a die-casting mechanism, which includes a die-casting machine body and an L-shaped support base. The die-casting machine body and the L-shaped support base are fixedly installed on the top of the support base, and the support frame is fixedly installed on the top of the die-casting machine body and the L-shaped support base via support legs. With this preferred embodiment, the die-casting machine body hydraulically casts metal into the cavity, thereby die-casting the metal parts.

[0009] Preferably, the die-casting mechanism further includes a fixed mold and a hydraulic cylinder. The fixed mold is fixedly mounted on an L-shaped support, and the hydraulic cylinder is fixedly mounted on the left side of the L-shaped support. With this preferred embodiment, by activating the hydraulic cylinder, the rod inside the hydraulic cylinder pushes the moving mold to move.

[0010] Preferably, the die-casting mechanism further includes a moving mold, which is slidably connected to an L-shaped support via a slider.

[0011] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0012] 1. This die-casting device for producing metal furnace parts, through the coordinated action of a support frame, storage tank, delivery pump, connecting hose, cleaning nozzle, threaded sleeve, screw, limit lifting rod, motor, and helical gear set, allows the screw to push the cleaning nozzle downwards. By activating the delivery pump, the pump extracts the mold release agent mixed inside the storage tank, then delivers it to the connecting hose, and finally sprays it out through the cleaning nozzle. This demolding process removes the mold material from the cavity, facilitating the die-casting of the next part material. It also forms a protective film on the surface of the mold cavity, reducing the thermal shock, chemical corrosion, and mechanical wear of the mold caused by the molten metal during the die-casting process.

[0023] Please see Figure 1-4 One embodiment of this utility model is: a die-casting device for producing metal furnace accessories, including a support base 1, on which a demolding mechanism 21 is provided. The demolding mechanism 21 includes a support frame 211, a storage tank 212, a conveying pump 213, a connecting hose 214, a cleaning nozzle 215, a threaded sleeve 216, and a screw 217.

At the top, the top end of the screw 217 is threadedly connected to the inner wall of the threaded sleeve 216, and the bottom end of the screw 217 is fixedly connected to the top of the cleaning nozzle 215. The demolding mechanism 21 also includes a limiting lifting rod 218, which is fixedly installed on the support frame 211. The bottom end of the inner rod of the limiting lifting rod 218 is fixedly connected to the cleaning nozzle 215. The demolding mechanism 21 also includes a motor 219 and a helical gear set 220. The motor 219 is fixedly installed on the top of the support frame 211.

A cavity is opened on the side of the moving mold 315 and the fixed mold 313 that are close to each other.

[0026] Working principle: By adding molten metal into the die-casting machine body 311, the hydraulic cylinder 314 is activated. The inner rod of the hydraulic cylinder 314 pushes the moving mold 315 to move, so that the moving mold 315 and the fixed mold 313 close together. The die-casting machine body 311 hydraulically casts the metal into the cavity, so that the metal parts are die-cast and formed. The inner rod of the hydraulic cylinder 314 drives the moving mold 315 to move, so that the formed metal parts can be taken out by an external material handling robot.
