Description

Technical Field

[0001] The invention relates to the technical field of metal product die-casting machines, and in particular to a metal product die-casting molding machine. Background Art

[0002] The die-casting machine is a series of industrial casting machines that hydraulically injects molten metal into a mold under pressure, cools it, and then forms it into a solid metal casting after the mold is opened. It was originally used for die-casting lead type. With the progress of science and technology and industrial production, especially with the development of industries such as automobiles, motorcycles, and home appliances, die-casting technology has achieved extremely rapid development.

[0003] In the die-casting process of the existing metal product die-casting machine, after the molten metal is die-casted, the mold needs to be opened, and then the molded metal product in the mold is taken out by the feeding mechanism, and then the cooling liquid is sprayed on the mold surface by the cooling mechanism. After the above steps are completed, the next die-casting is performed, resulting in a long waiting time in the die-casting process, resulting in reduced processing efficiency of the metal product. At the same time, when injecting materials, the current die-casting machine usually uses a feeding spoon to take the molten metal in the molten furnace and feed it into the injection groove on the injection pipe. During the feeding process, the molten metal cannot be accurately controlled, resulting in some precision metal products having low quality after die-casting. At the same time, during the injection process, due to the open type of the feeding groove, the molten metal is easy to overflow during injection, or when the push rod is pushed during feeding, the molten metal is easy to splash out in the open feeding groove, so that the amount of molten metal pushed into the mold is insufficient, resulting in the casting after die-casting.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Embodiment 1 See also Figure 1-Figure 10 As shown, the present invention is a die-casting machine for metal products, including a mounting table 1, a mounting frame 2 is fixedly connected to the mounting table 1, a slide rail 3 is fixedly connected inside the mounting frame 2, a transmission plate 4 is slidably connected to the slide rail 3, a first electric telescopic rod 5 fixedly connected to the mounting frame 2 is fixedly connected to one side of the transmission plate 4, a die-casting molding mechanism is arranged on the transmission plate 4, the die-casting molding mechanism is used for die-casting the metal product, a molding die 6 is fixedly connected to the mounting frame 2, a feeding mechanism fixedly connected to the mounting frame 2 is fixedly connected to one side of the molding die 6, and the feeding mechanism is used for quantitatively feeding the molten metal.

[0023] The transmission plate 4 is driven to move by the first electric telescopic rod 5, and the transmission plate 4 drives the die-casting molding mechanism and the molding die 6 to close, and then the molten metal is injected into the cavity in the molding die 6 and the die-casting molding mechanism at a high speed through the feeding mechanism, and then cooled and formed. Then, the first electric telescopic rod 5 drives the transmission plate 4 to move backward to take the metal product formed on the die-casting molding mechanism, and at the same time cools the die-casting molding mechanism to dissipate heat, thereby realizing rapid die-casting of the metal product and greatly improving the forming efficiency of the metal product.

[0024] Embodiment 2 Based on Example 1, please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 8 and Fig.10As shown, the die-casting molding mechanism includes two transmission tubes 11 rotatably connected to the transmission plate 4, the opposite ends of the two transmission tubes 11 are fixedly connected to the first transmission block 12, the bottom of the first transmission block 12 is slidably connected to the transmission frame 13, the outer surface of the first transmission block 12 is fixedly connected to a plurality of first telescopic rods 14, one end of the first telescopic rod 14 is fixedly connected to a slider 15 slidably connected to the transmission frame 13, the outer surface of the first telescopic rod 14 is fixedly sleeved with a first spring 16 slidably connected to the slider 15, both sides of the slider 15 are fixedly connected to the second telescopic rod 17, the outer surface of the second telescopic rod 17 is fixedly sleeved with a second spring 18 fixedly connected to the transmission frame 13, the opposite sides of the two transmission frames 13 are fixedly connected to a four-sided die-casting mold 19 by bolts, and the top and bottom of the four-sided die-casting mold 19 are fixedly connected to the first lock by bolts. A tightening transmission block 190 is fixedly connected to a second electric telescopic rod 191 in the mounting frame 2, one end of the second electric telescopic rod 191 is fixedly connected to a second locking transmission block 192, the outer surface of the transmission tube 11 is transmission-connected to a driving mechanism connected to the transmission plate 4, the driving mechanism includes a driving motor 21 fixedly connected to the transmission plate 4, the driving motor 21 is controlled by a PLC programming program, and the driving motor 21 can be controlled to rotate forward and reverse and rotate at an angle, the output end of the driving motor 21 is fixedly connected to a driving shaft 22 through a coupling, the outer surface of the driving shaft 22 is fixedly sleeved with a first driving gear 23, the outer surface of the first driving gear 23 is meshingly connected to a second driving gear 24 fixedly sleeved with the transmission tube 11, and one end of the transmission tube 11 is provided with a water cooling mechanism connected to the mounting frame 2, and the water cooling mechanism is used to cool the four-sided die-casting mold 19.

[0025] The transmission plate 4 is driven to move quickly by the first electric telescopic rod 5, and the transmission plate 4 drives the transmission tube 11 to move. The transmission tube 11 drives the transmission frame 13 to move through the first transmission block 12 and the first telescopic rod 14 and the first spring 16 on the first transmission block 12. The transmission frame 13 drives the four-sided die-casting mold 19 to move, so that the four-sided die-casting mold 19 and the forming mold 6 are closed. At this time, since the first electric telescopic rod 5 drives the transmission plate 4 to move with a large stroke, the closing locking force of the four-sided die-casting mold 19 and the forming mold 6 is small. Then, the first electric telescopic rod 5 drives the transmission plate 4 to move with a large stroke, and the four-sided die-casting mold 19 and the forming mold 6 are closed. The second electric telescopic rod 191 drives the second locking transmission block 192 to move, and the second locking transmission block 192 pushes the first locking transmission block 190 on the four-sided die-casting mold 19 to move, and the first locking transmission block 190 drives the four-sided die-casting mold 19 to move, so that the four-sided die-casting mold 19 and the molding mold 6 are tightly locked and closed. At this time, during the movement, the first telescopic rod 14 and the first spring 16 are telescoped, the second telescopic rod 17 and the second spring 18 are telescoped, and at the same time, the slider 15 in the transmission frame 13 slides, so that the first transmission block 12 and The force on the transmission tube 11 is small, which prevents displacement and damage to the rotation connection between the transmission tube 11 and the transmission plate 4 during the locking process, thereby greatly improving the locking force between the die-casting molds, improving the sealing between the die-casting molds, and preventing the molten metal from overflowing, causing the quality of the formed metal product to be reduced. Subsequently, the molten metal is injected into the molding mold 6 at high speed and high pressure through the feeding mechanism, and then enters the four-sided die-casting mold 19 for cooling and die-casting. After the forming is completed, the second electric telescopic rod 191 and the first electric telescopic rod 5 are simultaneously contracted, and then the transmission tube 11 is driven by the driving mechanism to rotate 90°, so that the formed metal product is rotated to the front material taking position, and then taken out through the existing material taking mechanism, and at the same time, the four die-casting molds with the new side cooled are rotated to the die-casting position, and then the first electric telescopic rod 5 and the second electric telescopic rod 191 work to complete the die-casting of the next metal product, so that the die-casting machine does not need to wait for material taking and cooling after stamping, and the die-casting of the next metal product can be directly realized, which greatly reduces the waiting time and further improves the processing efficiency of the die-casting machine for metal products.

[0026] Embodiment 3 Based on Example 2, please refer to Figure 1 , Figure 5 , Figure 7 , Figure 8 and Fig.10As shown, the water cooling mechanism includes a connecting pipe 31 rotatably connected at both ends of the transmission pipe 11, the connecting pipe 31 is fixedly connected to the transmission plate 4, one end of the connecting pipe 31 is fixedly connected to a first hose 32, one end of the first hose 32 is fixedly connected to a water pump 33, the water pump 33 is fixedly connected to a water cooler 34 connected to the mounting frame 2 through a pipeline, the water cooler 34 is a prior art, so no further details are given here, the outer surface of the transmission pipe 11 is fixedly connected to a second hose 35 connected to the four-sided die-casting mold 19 through a pipeline, an electromagnetic valve is arranged on the second hose 35, and a heat dissipation groove 36 communicating with the second hose 35 is opened in the four-sided die-casting mold 19.

[0027] When the forming is completed, the formed metal product is driven to rotate to the front position, and then the material is taken through the material taking mechanism. At this time, the electromagnetic valve on the corresponding second hose 35 is opened, and the water pump 33 sends the cooling water in the water cooler 34 to the transmission pipe 11 through the pipeline and the first hose 32. Then the transmission pipe 11 passes the water into the heat dissipation groove 36 through the second hose 35, and then it is pumped into the water cooler 34 through the second hose 35 and the water pump 33 at the bottom for cooling, so as to realize the circulating water cooling of the surface of the four-sided die-casting mold 19. At the same time, the forming surface rotates three surfaces for the next die-casting forming, so as to realize the slow cooling of the forming surface and cool it to Sufficient cooling temperature reduces the damage to the die-casting mold caused by rapid cooling. At the same time, when it is rotated to the die-casting molding position, it is also cooled to a sufficiently low temperature to facilitate subsequent die-casting molding. At the same time, when it is rotated to this position, the electromagnetic valve of the second hose 35 at this position is closed to stop the flow of cooling water to prevent the die-casting mold temperature from suddenly rising and then suddenly falling during high-temperature die-casting. This causes damage to the inside of the die-casting mold and reduces the service life of the die-casting mold, thereby achieving sufficient cooling of the molding mold and slowly and gradually cooling the die-casting mold, which greatly reduces the damage to the die-casting mold caused by sudden cooling and increases the service life of the die-casting mold.

The quantitative feeding mechanism includes a feeding box 61 fixedly connected with the mounting platform 1, a pushing block 62 is slidably connected in the feeding box 61, and a second transmission block 63 is fixedly connected to the outer surface of the pushing block 62. Two transmission threaded rods 64 threadedly connected with the second transmission block 63 are rotatably connected on the mounting platform 1, and the two transmission threaded rods 64 are connected by a transmission wheel and a transmission belt. One end of one of the transmission threaded rods 64 is fixedly connected with a first motor 65 fixedly connected with the mounting platform 1 through a coupling. The first motor 65 is controlled by a PLC programming program, and the first motor 65 can be controlled to rotate forward and backward and rotate at an angle. A feeding pipe 66 is fixedly connected to the top of 61, a melting mechanism connected to the mounting platform 1 is fixedly connected to the top of the feeding box 61, the melting mechanism includes a melting box 71 fixedly connected to the mounting platform 1, a feeding pipe 72 fixedly connected to the feeding box 61 is fixedly connected to the bottom of the melting box 71, a degassing mechanism connected to the mounting platform 1 is arranged in the melting box 71, and is used to remove gas in the melt, the degassing mechanism includes a mounting frame 73 fixedly connected to the mounting platform 1, a degassing pipe 74 is rotatably connected to the mounting frame 73, a plurality of stirring pipes 75 are fixedly connected to the degassing pipe 74, the outer surface of the degassing pipe 74 is connected to the second motor 76 fixedly connected to the mounting frame 73 through a transmission belt and a transmission wheel, and the top of the degassing pipe 74 is rotatably connected to the air supply pipe 77,The gas supply pipe 77 is fixedly connected to the mounting frame 73, and the top of the gas supply pipe 77 is fixedly connected to an argon gas blower 78 fixedly connected to the mounting frame 73 through a pipeline.

[0029] The metal ingot is turned over into the melting box 71 for melting, and the second motor 76 drives the degassing pipe 74 to rotate through the transmission shaft, the transmission wheel and the transmission belt. The degassing pipe 74 drives multiple stirring tubes 75 of different lengths to rotate. During the rotation, the argon blower 78 is connected to the argon tank, and the argon is sent into the degassing pipe 74 through the pipeline and the gas supply pipe 77. Then, the degassing pipe 74 blows out the argon bubbles through the multiple stirring tubes 75, so that the gas and slag in the molten metal are taken out, thereby achieving the degassing of the molten metal. Then, the transmission threaded rod 64 is driven to rotate by the first motor 65, and the transmission threaded rod 64 drives the second transmission block 63 and the push The block 62 moves out of the feeding box 61 so that the feeding tube 72 at the bottom of the molten material box 71 is no longer blocked, and then the molten metal enters the feeding box 61, filling the feeding box 61 with the molten metal. At the same time, the outer surface of the feeding box 61 is fixedly connected with an electric heating wire and a heat preservation plate for heat preservation, and then the pushing block 62 is driven to move to block the feeding tube 72. When the die-casting mold is performing die-casting, the transmission threaded rod 64 is driven to rotate by controlling the first motor 65, and the transmission threaded rod 64 drives the second transmission block 63 and the pushing block 62 to move, so that the molten metal in the feeding box 61 is quantitatively fed into the metering cylinder 48 through the feeding tube 66, and then through the first The four electric telescopic rods 45 drive the connecting plate 46 to move downward, and the connecting plate 46 drives the feed pipe 47 and the metering cylinder 48 to move downward. At the same time, the feed pipe 47 drives the sealing plate 49 to move downward, so that the sealing plate 49 is tightly fitted with the feed groove 44 on the injection pipe 41. At the same time, during the downward movement, the first pressing block 58 abuts against the second pressing block 590, driving the transmission rod 57 to move downward, and the transmission rod 57 drives the second transmission inclined block 56 to move upward. The second transmission inclined block 56 drives the first transmission inclined block 53 and the sealing block 52 to move out of the transmission box 51. At this time, the third spring 55 and the third telescopic rod 54 are contracted. At this time, the sealing block 52 in the feed pipe 47 is opened. The molten metal in the metering cylinder 48 enters the injection tube 41, and then the compression rod 42 is driven by the third electric telescopic rod 43 to move at high speed, and the molten metal is injected into the molding die at high speed and high pressure. At the same time, the sealing plate 49 is used to seal the feed groove 44, so that the molten metal is not easy to spill out when the injection tube 41 is injected. Through this mechanical transmission, the influence of the high temperature of the molten metal on the structure when the electrical components are used is avoided, thereby realizing accurate and quantitative stable feeding in the injection tube 41, and effectively removing the gas in the molten metal. At the same time, the contact between the molten metal and the air is avoided in the whole feeding process, which greatly reduces the influence of the gas on the metal products after die-casting.

[0030] The working principle of the present invention is as follows: the transmission plate 4 is driven to move by the first electric telescopic rod 5, and the transmission plate 4 drives the die-casting molding mechanism and the molding mold 6 to close, and then the molten metal is injected into the molding mold 6 and the cavity in the die-casting molding mechanism at a high speed through the feeding mechanism, and then cooled and formed, and then the first electric telescopic rod 5 drives the transmission plate 4 to move backward to take the metal product formed on the die-casting molding mechanism, and at the same time cools the die-casting molding mechanism to dissipate heat, thereby realizing rapid die-casting molding of the metal product and greatly improving the forming efficiency of the metal product.

[0031] At the same time, the water cooling mechanism is used to achieve sufficient and slow heat dissipation of the Smyrna die-casting mold, thereby achieving sufficient cooling of the molding mold. At the same time, the die-casting mold is cooled slowly and gradually, which greatly reduces the damage caused by sudden cooling to the die-casting mold and increases the service life of the die-casting mold.

[0032] The molten metal is quantitatively and accurately injected into the injection pipe 41 on the die-casting machine through the feeding mechanism, and the molten metal is degassed at the same time. At the same time, the feeding groove 44 is sealed by the sealing plate 49, so that the molten metal is not easy to spill out when the injection pipe 41 is injected. Through this mechanical transmission, the influence of the high temperature of the molten metal on the structure when using electrical components is avoided, thereby achieving accurate and quantitative stable feeding in the injection pipe 41, and effectively removing the gas in the molten metal. At the same time, the contact between the molten metal and the air is avoided in the whole feeding process, which greatly reduces the influence of gas on the metal products after die-casting.

[0033] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
