Description

Technical Field

[0001] The present invention relates to the technical field of cold chamber die casting machines, and particularly to a cold chamber die casting machine for casting. Background Technique

[0002] Forging is a processing method that uses forging machinery to apply pressure to metal billets, causing them to undergo plastic deformation to obtain forgings with certain mechanical properties, certain shapes, and dimensions. It is one of the two major components of forging and stamping (forging and punching). Through forging, defects such as as-cast porosity generated during the smelting process of metals can be eliminated, the microstructure can be optimized. At the same time, due to the preservation of the complete metal streamline, the mechanical properties of forgings are generally superior to those of castings made of the same material. For important parts with high loads and severe working conditions in related machinery, except for those with relatively simple shapes that can use rolled plates, profiles, or welded parts, most use forgings. Castings usually need to be processed using a die casting machine during the forging process.

[0003] A die casting machine is a machine used for die casting. It includes two types: hot chamber and cold chamber. The latter is further divided into two types: vertical and horizontal. Under pressure, the die casting machine injects molten metal into the mold for cooling and forming. After opening the mold, solid metal castings can be obtained. It was initially used for die casting type. With the progress of science and technology and industrial production, especially with the development of industries such as automobiles, motorcycles, and household appliances, die casting technology has developed extremely rapidly.

[0004] In the die casting process of the above-mentioned traditional die casting machine, feeding needs to be carried out through a pouring port. However, when in use, the molten metal solution enters the lower mold through the pouring port, and the molten metal solution is easily adhered to the pouring port, resulting in incomplete entry of the material into the lower mold, affecting the completeness of the material entry and causing a certain problem of raw material waste.

At the same time, by rotating the screw rod, under the action of the thread, the clamping block is driven to embed into the card slot to lock the pushing plug. During die casting, the metal solution will not flow back through the pouring port, further saving the use cost and other advantages, and solving the problems raised in the background technique.

Detailed implementation manners

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment Refer to Figures 1-6 As shown, a cold chamber die casting machine for casting includes a machine body 1. A lower die 211 is fixed at the top of the machine body 1. A bracket 212 is fixed at the top of the machine body 1. A hydraulic rod 213 is installed at the top of the bracket 212. The output end of the hydraulic rod 213 is connected to a mounting plate 411. The outer wall of the mounting plate 411 is connected to an upper die 214 through a limiting mechanism. By starting the hydraulic rod 213 to drive the mounting plate 411 and the upper die 214 to press down, the upper die 214 can be embedded into the lower die 211 to achieve the die casting effect.

[0021] A pouring pipe 215 is fixed on the side wall of the lower die 211. A pouring port 216 communicating with the inside of the lower die 211 is opened inside the pouring pipe 215. The molten metal solution enters the lower die 211 through the pouring port 216 to achieve the purpose of feeding. Two groups of fixing plates 218 are fixed on the side wall of the machine body 1. A rotating plate 219 is rotatably connected to the opposite side surfaces of the two groups of fixing plates 218. A pushing plug 217 corresponding to the pouring port 216 penetrates through the rotating plate 219. By rotating the rotating plate 219 to drive the pushing plug 217 to correspond to the pouring pipe 215 and the pouring port 216, after moving the pushing plug 217, the pushing plug 217 is inserted into the pouring port 216, and the metal solution on the inner wall of the pouring port 216 is completely pushed into the lower die 211, thereby avoiding waste of raw materials.

[0022] A connecting plate 221 is fixed to the side of the rotating plate 219 away from the fixed plate 218. A threaded sleeve 223 is fixed to the top of the connecting plate 221. A screw rod 224 is threadedly connected to the inner wall of the threaded sleeve 223. A clamping block 222 is rotatably connected to the bottom of the screw rod 224. A clamping groove 220 corresponding to the clamping block 222 is formed at the top of the pushing plug 217. The rotating plate 219 rotates on the fixed plate 218, driving the pushing plug 217 to correspond to the pouring pipe 215 and the pouring port 216. Move the pushing plug 217 so that the pushing plug 217 is inserted into the pouring pipe 215, and push the molten metal remaining on the inner wall of the pouring port 216 completely into the lower die 211. Finally, rotate the screw rod 224, and under the action of the internal thread of the inner wall of the threaded sleeve 223 and the external thread of the outer wall of the screw rod 224, drive the clamping block 222 to be embedded into the clamping groove 220, so that the position of the pushing plug 217 can be locked. The pushing plug 217 can completely close the pouring port 216, and during the die-casting process, the solution will not flow back through the pouring port 216.

[0023] A top plate 318 is attached to the inner wall of the bottom end of the lower die 211. A ejector rod 317 passing through the fuselage 1 is fixed to the bottom end of the top plate 318. Push the ejector rod 317 upward to drive the top plate 318 and the die-cast material to move upward to achieve the discharging effect. A movable block 315 is fixed to the bottom end of the ejector rod 317. A first spring 319 is wound around the outer wall of the ejector rod 317. One end of the first spring 319 is connected to the bottom of the fuselage 1, and the other end is connected to the movable block 315. The first spring 319 is provided with a good elastic reset effect. In the initial state, the first spring 319 is in an extended state. By pushing the movable block 315 upward, the ejector rod 317 and the top plate 318 are driven to rise, compressing the first spring 319; after releasing the movable block 315, the top plate 318 rebounds under the elasticity of the first spring 319 and fits against the bottom end of the lower die 211.

[0024] A vertical plate 311 is fixed to the bottom end of the fuselage 1. A motor 312 is installed on the outer wall of the vertical plate 311. The output end of the motor 312 is connected to a rotating rod 313. A rotating wheel 314 is fixed to the end of the rotating rod 313 away from the motor 312. A roller 316 corresponding to the rotating wheel 314 is rotatably connected to the inner wall of the movable block 315. After starting the motor 312, the rotating rod 313 and the rotating wheel 314 are driven to rotate. The rotating wheel 314 pushes the roller 316 to rotate, and the roller 316, the movable block 315, the ejector rod 317 and the top plate 318 are driven to rise, realizing an automatic discharging effect.

[0025] The limiting mechanism includes a groove 412, a fixed cylinder 413, an insertion block 414, and a second spring 415. The groove 412 is formed on the side wall of the mounting plate 411. A fixed cylinder 413 is fixed to the top end of the upper die 214. An insertion block 414 corresponding to the groove 412 is connected to the inner wall of the fixed cylinder 413 through the second spring 415. Under the elasticity of the second spring 415, the insertion block 414 can be pushed to slide inside the fixed cylinder 413 and be inserted into the groove 412 to lock and limit the mounting plate 411 and the upper die 214. The staff can move the insertion block 414 to remove the upper die 214, so as to achieve the purpose of replacing the upper die 214. A movable rod 416 is fixed to the outer wall of the insertion block 414. One end of the movable rod 416 away from the insertion block 414 extends out of the outer wall of the fixed cylinder 413, and the second spring 415 is wound around the outer wall of the movable rod 416. The arrangement of the movable rod 416 can facilitate pulling the insertion block 414 in and out of the groove 412, making the operation more comfortable, time-saving and labor-saving. A handle 417 is fixed to one end of the movable rod 416 away from the insertion block 414. The diameter of the handle 417 is larger than that of the movable rod 416. The handle 417 has a good limiting effect. Under the elasticity of the second spring 415, the movable rod 416 can be prevented from being completely inserted into the fixed cylinder 413, which may affect the use and operation.

[0026] Working principle: When it is necessary to push the molten metal solution in the pouring port 216 into the lower die 211, the rotating plate 219 is rotated to drive the pushing plug 217 to correspond to the pouring port 216. Subsequently, the pushing plug 217 is moved to push the metal solution on the inner wall of the pouring port 216 into the lower die 211. At this time, the pushing plug 217 can completely close the pouring port 216 and push the material into the lower die 211. When discharging is required, the motor 312 is started to drive the rotating rod 313 and the rotating wheel 314 to rotate. The rotating wheel 314 rolls along the roller 316 and drives the roller 316 to rotate. The long axis end of the rotating wheel 314 pushes the roller 316, the movable block 315, the ejector rod 317, and the top plate 318 to rise, driving the first spring 319 to be compressed. The top plate 318 pushes the material to move upward and separate from the top of the lower die 211. When the upper die 214 needs to be disassembled, the handle 417 is pulled to move the movable rod 416 and the insertion block 414. The insertion block 414 can be separated from the inside of the groove 412 and drive the second spring 415 to be compressed. Subsequently, the upper die 214 is pulled downward to remove the upper die 214. During installation, the upper die 214 is attached to the bottom of the mounting plate 411. After the handle 417 is released, the insertion block 414 is driven by the elasticity of the second spring 415 to be inserted into the inside of the groove 412, achieving the purpose of locking the mounting plate 411 and the upper die 214.
