Description

Technical Field

[0001] This invention relates to the field of metal casting technology, and more specifically to an automatic demolding device for heat-resistant and wear-resistant casting. Background Technology

[0002] Casting molds are important process equipment in industrial manufacturing, mainly used to obtain parts with specific structural shapes. Mold casting involves pouring molten metal or alloy into a mold, allowing it to cool and solidify within the mold cavity, thus forming a part that conforms to the shape of the mold. The part is then removed from the mold and cleaned and processed as necessary. This process of removing the formed part from the mold is called the demolding process. Nowadays, most demolding processes for castings rely on automated devices. In automatic demolding devices, when the casting cools to a sufficient temperature, the control system issues a command, the drive device starts working, and the ejection mechanism, under the action of the drive device, ejects the casting from the mold. After being ejected, the casting can be transported to the next process for further processing by a conveyor device.

[0003] The control system of the automatic demolding device is responsible for receiving operation commands, controlling the action of the drive device, and monitoring the entire demolding process. It even relies on components such as sensors and controllers to monitor mold temperature changes in order to achieve automated and intelligent operation. This makes the overall cost of the automatic demolding device high, increasing the operating costs of enterprises and making it unsuitable for small and medium-sized workpiece manufacturing enterprises. Summary of the Invention

The transmission air pipe includes a frame assembly comprising a connecting frame, a slide rail block fixedly connected to the inner side of one side of the connecting frame, and a first gear connected to the pivot of the other side of the connecting frame. The demolding assembly includes a cylinder, a piston movably sleeved on the inner side of the cylinder, a second spring fixedly connected to the bottom of the piston, a mounting base plate fixedly connected to the bottom of the second spring, a mounting base plate fixedly connected to the bottom of the cylinder, a connecting piece fixedly connected to the top of the piston, a first connecting rod rotatably sleeved on the side of the connecting piece, a first connecting strip fixedly connected to both ends of the side of the first connecting rod, a second connecting rod fixedly connected to the top ends of the two first connecting strips, and a second gear fixedly connected to one end of the second connecting rod.

[0006] Furthermore, the casting assembly includes an injection mold, with connecting blocks fixedly connected to both ends of the cavity of the injection mold, first springs fixedly connected to the tops of the two connecting blocks, annular plates fixedly connected to the tops of the two first springs, and a steam chamber fixedly connected to the top of the injection mold.

[0007] Furthermore, the feeding assembly includes a feeding pipe, the top of the steam chamber is movably sleeved with the feeding pipe, and the bottom of the feeding pipe is fixedly sleeved with an upper top plate.

[0008] Furthermore, a mounting base plate is fixedly connected to the bottom of the connecting frame, a lower support plate is fixedly connected to the middle of the top of the mounting base plate, a water pump is fixedly connected to one end of the top of the mounting base plate, a water inlet pipe is connected to the bottom pipe on one side of the water pump, and a transmission water pipe is connected to the pipe on the back of the water pump.

[0009] Furthermore, the second gear meshes with the first gear on its side, and the back of the second gear is rotatably connected to an intermediate shaft. A second connecting strip is fixedly connected to one side of the intermediate shaft, and a connecting frame is fixedly connected to one end of the second connecting strip. A transmission air pipe is connected to the bottom pipe on the back of the cylinder.

[0010] Furthermore, the wall of the injection mold is hollow, forming an inner cavity, and the size of the annular piece is the same as the size of the cavity of the injection mold.

[0011] Furthermore, the bottom area of ​​the upper top plate is the same as the area inside the injection mold.

[0012] Furthermore, the lower support plate is the same size as the upper top plate, and the side of the lower support plate is movably sleeved on the bottom of the injection mold.

[0013] Furthermore, the second connecting rod is fixedly connected to the edge position on the front side of the second gear.

[0014] The technical effects and advantages of this invention are as follows:

[0015] 1. This invention features a molding assembly with a hollow injection mold shell. A feed pipe delivers molten metal into the mold, and a water pipe injects water into the mold cavity. The injected cold water cools the casting, promoting rapid molding. Simultaneously, the cold water rapidly vaporizes upon contact with the high temperature generated by the molten metal, forming a large amount of steam. This increases the pressure within the mold cavity, causing the steam to expand and break open the annular strip. The steam then enters the steam chamber, powering the demolding assembly. This design facilitates rapid molding of the molten metal and avoids expensive equipment costs.

[0016] 2. This invention features a demolding assembly. One end of a transmission pipe is connected to a steam chamber, and the other end is connected to a cylinder. Steam from the steam chamber is transmitted into the cylinder, pushing a piston upward. A connecting piece is attached to the top of the piston. Under the action of a first connecting rod and a second connecting rod, a second gear rotates. The second gear meshes with the first gear, causing the first gear to rotate as well. The first gear meshes with a rack, causing the casting assembly to move upward while the feeding assembly remains stationary. The top plate presses the casting down to demold it. When the steam in the steam chamber is used up, the piston returns to its original position under the pull of a second spring. Similarly, the casting assembly also returns to its original position. This design helps reduce mold damage, improves production efficiency, and lowers the cost of casting production. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The automatic demolding device for heat-resistant and wear-resistant casting involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Reference Figure 1 The present invention provides an automatic demolding device for heat-resistant and wear-resistant casting, including a mold assembly 1, a frame assembly 2 movably connected to the bottom of the mold assembly 1, and a demolding assembly 3 movably connected to one side of the frame assembly 2.

[0027] In this embodiment, it is necessary to further explain that the mold assembly 1 uses cold water to cool the casting and enable it to form quickly. On the other hand, the cold water vaporizes rapidly when it encounters the high temperature generated by the molten metal, forming a large amount of water vapor, which provides power for the demolding assembly 3. This is beneficial for promoting the rapid forming of the molten metal and avoiding expensive equipment costs. The demolding assembly 3 helps to reduce mold damage, improve production efficiency, and reduce the production cost of castings. The specific structure and working principle of the above-mentioned components will be explained in detail later.

[0028] Reference Figure 2The casting mold assembly 1 includes a casting assembly 101. A steam chamber 102 is fixedly connected to the top of the casting assembly 101. A pulley assembly 103 is fixedly connected to one side of the casting assembly 101. A rack 104 is fixedly connected to the other side of the casting assembly 101. A feeding assembly 105 is movably sleeved on the top of the steam chamber 102. A first gear 203 is meshed with one side of the rack 104. A connecting frame 201 is fixedly sleeved on the side of the top of the feeding assembly 105.

[0029] Reference Figure 3 The back pipe of the casting component 101 is connected to a water transmission pipe 106, and the back pipe of the steam chamber 102 is connected to a gas transmission pipe 107.

[0030] Reference Figure 4 The casting assembly 101 includes an injection mold 1011. Both ends of the cavity of the injection mold 1011 are fixedly connected to connecting blocks 1012. The tops of the two connecting blocks 1012 are fixedly connected to first springs 1013. The tops of the two first springs 1013 are fixedly connected to annular plates 1014. The top of the injection mold 1011 is fixedly connected to a steam chamber 102. The top of the steam chamber 102 is movably sleeved with a feed pipe 1051. The bottom of the feed pipe 1051 is fixedly sleeved with an upper top plate 1052.

[0031] In this embodiment, it is necessary to further explain that the wall shell of the injection mold 1011 is hollow, forming an inner cavity. The size of the annular plate 1014 is the same as the size of the cavity of the injection mold 1011. The bottom area of ​​the upper top plate 1052 is the same as the internal area of ​​the injection mold 1011. The feed pipe 1051 transports the molten metal solution into the interior of the injection mold 1011. Water is injected into the cavity of the injection mold 1011 through the water transmission pipe 106. The injected cold water has a cooling effect on the casting, enabling it to form quickly. On the other hand, the cold water vaporizes rapidly when it encounters the high temperature generated by the molten metal solution, forming a large amount of water vapor. This increases the air pressure in the cavity of the injection mold 1011. The water vapor expands and pushes open the annular plate 1014. The water vapor enters the steam chamber 102 to provide power for the demolding assembly 3, which is beneficial for promoting the rapid forming of the molten metal solution and avoiding expensive equipment costs.

[0032] Reference Figure 5The frame assembly 2 includes a connecting frame 201. A slide block 202 is fixedly connected to the inner side of one side of the connecting frame 201. A first gear 203 is connected to the pivot on the other side of the connecting frame 201. A mounting base plate 204 is fixedly connected to the bottom of the connecting frame 201. A lower support plate 205 is fixedly connected to the middle of the top of the mounting base plate 204. A water pump 206 is fixedly connected to one end of the top of the mounting base plate 204. A water inlet pipe 207 is connected to the bottom pipe on one side of the water pump 206. A water transmission pipe 106 is connected to the back pipe of the water pump 206.

[0033] In this embodiment, it should be specifically noted that the size of the lower support plate 205 is the same as that of the upper top plate 1052, and the bottom of the injection mold 1011 is movably sleeved on the side of the lower support plate 205.

[0034] Reference Figure 6 The demolding assembly 3 includes a cylinder 301, a piston 302 is movably sleeved on the inner side of the cylinder 301, a second spring 303 is fixedly connected to the bottom of the piston 302, a mounting base plate 204 is fixedly connected to the bottom of the second spring 303, a mounting base plate 204 is fixedly connected to the bottom of the cylinder 301, a connector 304 is fixedly connected to the top of the piston 302, a first connecting rod 305 is rotatably sleeved on the side of the connector 304, a first connecting strip 306 is fixedly connected to both ends of the side of the first connecting rod 305, a second connecting rod 307 is fixedly connected to the top of the two first connecting strips 306, a second gear 308 is fixedly connected to one end of the second connecting rod 307, and a first gear 203 meshes with the side of the second gear 308.

[0035] In this embodiment, it should be specifically explained that the second connecting rod 307 is fixedly connected to the edge of the front of the second gear 308. When the piston 302 moves upward, the connecting member 304 pushes the first connecting rod 305, the first connecting bar 306, and the second connecting rod 307 to make the second gear 308 rotate.

[0036] Reference Figure 7 The back of the second gear 308 is rotatably connected to an intermediate shaft 309. A second connecting strip 310 is fixedly connected to one side of the intermediate shaft 309. A connecting frame 201 is fixedly connected to one end of the second connecting strip 310. A transmission air pipe 107 is connected to the bottom pipe on the back of the cylinder 301.

[0037] In this embodiment, it is necessary to further explain that one end of the transmission pipe 107 is connected to the steam chamber 102, and the other end is connected to the cylinder 301. The steam in the steam chamber 102 is transmitted into the cylinder 301. The steam entering the cylinder 301 pushes the piston 302 upward. The top of the piston 302 is connected to the connecting piece 304. Under the action of the lower support plate 205 and the second connecting rod 307, the second gear 308 rotates. The second gear 308 meshes with the first gear 203, and the corresponding first gear 203 also rotates. The first gear 203 meshes with the rack 104, causing the casting component 101 to move upward, while the feeding component 105 remains stationary. The upper top plate 1052 presses the casting down to demold it. When the steam in the steam chamber 102 is used up, the piston 302 returns to its original position under the pull of the second spring 303. Similarly, the casting component 101 also returns to its original position. This helps to reduce mold damage, improve production efficiency, and reduce the production cost of castings.

[0038] The working principle of this invention is as follows: Molten metal solution is transported into the injection mold 1011 through the feed pipe 1051. Water is injected into the wall cavity of the injection mold 1011 through the water transmission pipe 106. The injected cold water has a cooling effect on the casting, enabling it to form quickly. On the other hand, the cold water vaporizes rapidly when it encounters the high temperature generated by the molten metal solution, forming a large amount of water vapor. This increases the air pressure in the wall cavity of the injection mold 1011. The water vapor expands and pushes open the annular plate 1014. The water vapor enters the steam chamber 102 to provide power for the demolding component 3. This is beneficial for promoting the rapid forming of the molten metal solution and avoiding expensive equipment costs.

[0039] One end of the transmission pipe 107 is connected to the steam chamber 102, and the other end is connected to the cylinder 301. The steam in the steam chamber 102 is transmitted into the cylinder 301. The steam entering the cylinder 301 pushes the piston 302 upward. The top of the piston 302 is connected to the connecting piece 304. Under the action of the lower support plate 205 and the second connecting rod 307, the second gear 308 rotates. The second gear 308 meshes with the first gear 203, and the first gear 203 also rotates accordingly. The first gear 203 meshes with the rack 104, causing the casting component 101 to move upward, while the feeding component 105 remains stationary. The upper top plate 1052 presses the casting down to demold it. When the steam in the steam chamber 102 is used up, the piston 302 returns to its original position under the pull of the second spring 303. Similarly, the casting component 101 also returns to its original position. This helps to reduce mold damage, improve production efficiency, and reduce the production cost of castings.
