Description

Technical Field

[0001] The invention relates to the technical field of feeding equipment, and in particular to a segmented heating feeding system of a die-casting machine. Background Art

[0002] Liquid die forging equipment is generally worth mentioning die-casting machines. Die-casting machines are machines used for pressure casting, including hot pressing chambers and cold pressing chambers. The die-casting machine hydraulically injects molten metal into the mold under pressure to cool and form. After the mold is opened, solid metal castings can be obtained. It was originally used for die-casting lead type. Die-casting machines are generally divided into cold die-casting machines and hot die-casting machines. They are generally used for the production of castings of low-melting-point materials such as zinc alloys and magnesium alloys. The basic working principle of the die-casting machine is to hydraulically inject molten metal into the mold through the ejection rod under pressure to cool and form. This process is usually called injection molding.

[0003] In order to heat and melt the raw materials, they need to be transported to the inside of the barrel. The traditional feeding method generally connects a larger material box to the barrel, and then uses the gravity of the material inside the material box or mechanical devices such as vibrating feeders to transport the material to the inside of the barrel. Although these methods can perform feeding operations, this method generally continuously transports materials to the inside of the barrel, which may cause the material to be unevenly distributed in the barrel, especially when there are differences in material particle size, shape or density, this unevenness may be more obvious. The uneven distribution of materials in the barrel will lead to uneven amount of melted liquid, which in turn leads to uneven distribution of the melted liquid in the barrel. In addition, this method cannot accurately control the amount of material entering, and inaccurate metering may cause the amount of melted liquid to be unstable during processing, thereby affecting the effect of the processed product. Summary of the invention

[0027] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0028] like Figures 1 to 9As shown, a segmented heating and feeding system of a die-casting machine of the present invention includes a material box 10 and a heating and feeding assembly 40. The heating and feeding assembly 40 is located below the material box 10, and is used to heat and transport the raw materials. It also includes a hopper 20, a feed pipe 30, a push assembly 50, a recovery and return assembly 60, an isolation plate 70, a stirring assembly and a partition feeding assembly 80. There are multiple hoppers 20, and multiple hoppers 20 are installed at the bottom position of the material box 10. The hopper 20 is used to store a specific amount of raw materials. The feed pipe 30 is arranged at the bottom end of the hopper 20, and the feed pipe 30 corresponds to the hopper 20 one by one. The outer peripheral surface of the heating and feeding assembly 40 is connected to the bottom ends of the multiple feed pipes 30, and the multiple feed pipes 30 are each provided with an electromagnetic valve 31 The pushing assembly 50 is installed on one side of the material box 10, and the pushing assembly 50 is used to push the raw materials inside the material box 10 to move. The recycling and returning assembly 60 is installed on the side of the material box 10 away from the pushing assembly 50. The recycling and returning assembly 60 is used to collect the raw materials pushed by the pushing assembly 50, and the recycling and returning assembly 60 re-transports the raw materials to the inside of the material box 10. The isolation plate 70 is installed in the inside of the material box 10. The isolation plate 70 is used to divide the inside of the material box 10 into two spaces of different sizes. The stirring assembly is installed on the isolation plate 70. The stirring assembly is used to stir the material inside the material box 10. The partition feed assembly 80 is installed at the top position of the material box 10. The partition feed assembly 80 is used to divide the inside of the material box 10 into multiple separate spaces.

[0029] It should be noted that the top side of the hopper 20 passes through the bottom side of the material box 10 and extends to the interior of the material box 10, and the top side of the hopper 20 and the bottom side of the interior of the material box 10 are on the same horizontal plane, and a portion of the isolation plate 70 is located inside the hopper 20 and connected to the hopper 20, which can facilitate the subsequent installation of the stirring assembly.

[0030] The partition feeding assembly 80 includes a bracket 81 installed on the top side of the material box 10, a first electric push rod 82 is installed on the bracket 81, the output end of the first electric push rod 82 is connected to a moving plate 83, a plurality of partition plates 84 are connected to the moving plate 83, the partition plates 84 pass through the top side of the material box 10 and are slidably connected to the material box 10, and a feeding pipe 85 corresponding to the position of the hopper 20 is connected between the plurality of partition plates 84, the feeding pipe 85 passes through the top side of the material box 10 and is slidably connected to the material box 10.

[0031] When different kinds of materials need to be placed inside the material box 10, the first electric push rod 82 is used to make the movable plate 83 drive the partition plate 84 to move downward, so that the bottom side of the partition plate 84 fits tightly with the bottom side of the inside of the material box 10. At this time, the interior of the material box 10 is divided into multiple storage spaces by multiple partition plates 84, and the hopper 20 is located inside the storage space.

[0032] It should be noted that when the partition feed assembly 80 is not used, the partition plate 84 and the feeding pipe 85 are not located inside the material box 10.

[0033] The material pushing assembly 50 includes a second electric push rod 51 and a push plate 52 connected to an output end of the second electric push rod 51 . The second electric push rod 51 is installed on one side of the material box 10 .

[0034] It should be noted that the push plate 52 is located inside the large space divided by the isolation plate 70 into the interior of the material box 10, one side of the push plate 52 is in contact with the isolation plate 70, and the other sides of the push plate 52 are in contact with the interior of the material box 10, so that the push plate 52 can push the raw materials between the isolation plate 70 and the material box 10 to move.

[0035] The material recovery and return assembly 60 includes a return hopper 61 installed on one side of the material box 10. The return hopper 61 is tilted downward and is used to collect and store excess material inside the material box 10. A lifting cylinder 62 is connected to the end of the return hopper 61. The lifting cylinder 62 is vertically arranged. A conveying auger 63 is connected to the lifting cylinder 62. The conveying direction of the conveying auger 63 is upward. The lifting cylinder 62 and the conveying auger 63 are used to lift the material inside the return hopper 61 to a high position. A return pipe 64 is connected to the lifting cylinder 62, which is tilted and connected to the lifting cylinder 62. The end of the return pipe 64 is connected to the material box 10, and the return pipe 64 is connected to the material box 10.

[0036] When the recycling return component 60 is working, the material pushed by the pushing component 50 will be transported to the inside of the return hopper 61, and the material located inside the return hopper 61 will enter the inside of the lifting cylinder 62 for transportation through the conveying auger 63. When the material is transported to the top position of the lifting cylinder 62, the material will enter the inside of the return pipe 64 and under the conveying action of the return pipe 64, the material will be transported to the inside of the material box 10 again.

[0037] It should be noted that the end position of the return pipe 64 corresponds to the position of the hopper 20 farthest from the lifting cylinder 62, and can accurately transport the material to the interior of the hopper 20 farthest from the lifting cylinder 62, thereby facilitating the subsequent push plate 52 to push the material to move and push the material to the interior of the remaining hoppers 20.

[0038] The stirring assembly includes a stirring rod structure 71 which is rotatably connected to the isolation plate 70 and is located in the hopper 20. The stirring rod structure 71 is used to stir the material inside the hopper 20. The input end of the stirring rod structure 71 is connected to a belt drive structure. The input end of the belt drive structure is connected to a gear 72. The gear 72 and the belt drive structure are used to drive the stirring rod structure 71 to rotate.

[0039] It should be noted that the belt drive structure is located inside the small space divided by the isolation plate 70 into the interior of the material box 10, which can avoid the influence of the material on the belt drive structure and ensure the normal operation of the belt drive structure. The gear 72 is located inside the large space divided by the isolation plate 70 into the interior of the material box 10, and the rotating shaft is connected to the two pulleys in the belt drive structure. The rotating shaft is rotatably connected to the isolation plate 70, which can ensure the stability of the belt drive structure during the transmission process.

[0040] The push plate 52 is provided with an avoidance groove, and a rack 53 is fixedly installed on the inner wall of the avoidance groove. The position of the rack 53 corresponds to that of the gear 72 , and the rack 53 can mesh with the gear 72 .

[0041] The movement of the isolation plate 70 can drive the rack 53 to move. When the rack 53 moves to the position of the gear 72, the gear 72 will rotate due to the meshing transmission of the rack 53 and the gear 72. At this time, the stirring rod structure 71 will rotate and stir the material inside the hopper 20 under the transmission action of the belt drive structure.

[0042] It should be noted that the width of the avoidance groove is greater than the thickness of the gear 72, and the length of the avoidance groove is greater than the sum of the thickness of the rack 53 and the top circle diameter of the gear 72, thereby avoiding interference between the isolation plate 70 and the gear 72 during movement and ensuring smooth rotation of the subsequent gear 72.

[0043] The heating feeding assembly 40 includes a barrel 41 installed on the die-casting machine, and a feeding structure is arranged on the barrel 41. A plurality of heating sleeves 42 are arranged around the outer surface of the barrel 41. The interiors of the plurality of heating sleeves 42 are all filled with heating coils. The intervals between the plurality of heating sleeves 42 are the same. The heating sleeves 42 are used to heat the material inside the barrel 41 to make the material flow. A temperature measuring rod 43 is arranged on the plurality of heating sleeves 42. The temperature measuring rod 43 is connected to the heating sleeve 42, and a temperature sensor is arranged inside the temperature measuring rod 43. The temperature measuring rod 43 is used to monitor the temperature inside the barrel 41 in real time.

[0044] The working principle of the present invention for processing raw materials of the same kind and color is as follows:

[0045] The material is added to the inside of the material box 10 through multiple feeding pipes 85, so that the material fills the hopper 20 and continues to add material, so that the height of the material inside the material box 10 is less than the bottom side of the avoidance groove, and then the second electric push rod 51 is started to move the push plate 52. At this time, the push plate 52 pushes the material above the hopper 20 in the material box 10 to move and allow the material to enter the inside of the return hopper 61. In this process, when the rack 53 is meshed with the gear 72, the gear 72 will rotate, and under the transmission action of the belt drive structure, the stirring rod structure 71 will rotate and stir the material inside the hopper 20, and then the material can be stirred according to the method described above. Open a suitable number of solenoid valves 31 according to the actual situation during use. At this time, a specific amount of material located inside the hopper 20 enters the interior of the barrel 41 through the discharge pipe 30, and then is heated and melted by the heating sleeve 42 and the melted material is conveyed through the feeding structure to the interior of the die-casting structure of the die-casting machine for die-casting operation. When the material located inside the hopper 20 enters the interior of the barrel 41, the material can be lifted to a high place by the conveying auger 63 and the lifting cylinder 62 and enter the interior of the return pipe 64. Under the conveying action of the return pipe 64, the material re-enters the interior of the material box 10 and is accumulated inside the material box 10.

[0046] The working principle of the present invention for processing raw materials of different types or colors is as follows:

[0047] The first electric push rod 82 is started to make the moving plate 83 drive the partition plate 84 and the feeding pipe 85 to move downward. The partition plate 84 is tightly fitted with the bottom side of the inside of the material box 10, so that the inside of the material box 10 is divided into multiple spaces, and then different colors or different types of materials can be added to the inside of the hopper 20 through multiple feeding pipes 85, and then the solenoid valve 31 installed on a feeding pipe 30 is opened. At this time, a color or a type of material located in the hopper 20 enters the inside of the barrel 41 through the feeding pipe 30, and then the material is heated and melted by the heating sleeve 42 and the melted material is transported through the feeding structure, and the material is transported to the inside of the die-casting structure of the die-casting machine for die-casting operation, and then the solenoid valve 31 installed on a feeding pipe 30 can be opened to continue the die-casting operation of another color or type of material.

[0048] It should be noted that the tops of the multiple temperature measuring rods 43 are connected to transmission lines, through which the temperature signals measured by the temperature measuring rods 43 can be transmitted to the control processing system of the die-casting machine. The control processing system of the die-casting machine analyzes the temperature signals and adjusts the heating sleeves 42 at different positions to work, ensuring that the material inside the barrel 41 is heated evenly and the temperature is controllable.
