TECHNICAL FIELD

[0001] The present application relates to the technical field of alloy casting, in particular to a supercharged casting equipment for aluminum alloy casting. BACKGROUND

[0002] The supercharged casting machine is a special casting equipment combining low-pressure casting and forging pressure.

[0013] Preferably, the side of the cleaning strip away from the pushing rod is provided with an inclined edge, and the upper side of the inclined edge protrudes outward to form a triangular cleaning edge.

[0014] Preferably, the fixed tube is provided with a ventilation assembly for ventilation demolding into the upper compression mold.

[0017] Preferably, the opening and closing assembly comprises elastic connecting rods and opening and closing plates, the elastic connecting rods are fixedly connected inside the deflection groove, and the opening and closing plates are fixedly connected to the side edges of the elastic connecting rods.

[0020] Compared with the prior art, the present application has the following beneficial effects:

[0021] 1. After the casting is completed, the piston block is pushed by the hydraulic adjusting assembly to move inside the fixed pipe, thereby driving the push rod and the cleaning strip to move, and the cleaning strips on both sides scrape and clean the inner wall of the upper mold shell in the moving process. The cleaning strip not only has the demolding effect of separating the casting from the upper mold shell, but also scrapes and cleans the residual material generated in the moving process. The present application can push the casting out from both sides when the casting is demolded, reduces the extrusion deformation of the casting, and can also shovel the metal residues in the mold;

[0022] 2. The triangular cleaning strip edge can conveniently shovel the solidified residual material quickly. The cleaning strip cleans the residual material while assisting in demolding, thereby ensuring the cleanliness of the inside of the upper mold shell and avoiding the influence of the residual material on the subsequent casting forming. The triangular side edge of the cleaning strip can separate the side edge of the casting from the upper mold shell, thereby reducing the area of the hard extrusion between the cleaning strip and the casting, ensuring that the upper surface of the casting will not be deformed in the demolding process, and improving the integrity of the casting;

[0023] 3. The piston block extrudes the gas inside the air cavity space, the gas is introduced into the air guide channel through the plurality of inner gas ports, and the gas is uniformly sprayed into the gap between the upper mold shell and the casting through the plurality of gas outlets. Due to the setting of the fixed pipe diameter, a large amount of gas is sprayed out during the movement of the piston block, thereby accumulating a large amount of gas in the gap between the upper mold shell and the casting. The gas pressure is continuously increased to separate the upper mold shell and the casting. During the air separation process, the moving cleaning strip can quickly transfer the sprayed gas to the newly generated gap, and the cleaning strip can also scrape and separate the adhered metal residues;

[0024] 4. During the process of ventilation demoulding and mold vacuuming, the ventilation pipe can be connected to the vacuum pump and the inert gas pump according to the usage. During the vacuuming, the gas inside the mold can be completely extracted with the assistance of the vacuum pump. During the ventilation demoulding process, if the gas volume inside the fixed pipe is insufficient, the inert gas pump can be connected to introduce inert gas into the fixed pipe, thereby completing the ventilation demoulding of castings of different volumes.

[0025] 5. After the cleaning component is retracted into the placement slot, the opening and closing plate is reset under the elastic action of the elastic connecting rod, thereby closing the placement slot in one direction and preventing the molten metal from entering the placement slot during the material guiding process. When demoulding and cleaning are performed, the cleaning component moves outward, and the cleaning bar pushes the opening and closing plate, thereby deflecting the opening and closing plate outward, opening the notch of the placement slot, and the cleaning bar moves outward for demoulding and cleaning. After cleaning is completed, the opening and closing plate is reset again;

[0026] 6. Each time the cleaning strip is moved out of the placement slot, it comes into contact with the scraper bar, which scrapes the inclined side of the cleaning strip. The scraped residue will be transferred to the inside of the outlet and accumulated. Regularly clean the inside of the outlet by opening the sealing strip to reduce the accumulation of metal residue.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

[0038] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present application are only for the convenience of clear description, and are not used to limit the scope of the present application. The change or adjustment of the relative relationship is also regarded as the scope of the present application without substantial change of the technical content.

[0039] Referring to Figures 1-9 A supercharged casting equipment for aluminum alloy casting, comprising: a casting frame 1, a material guiding bottom die 2 and an upper pressing die 3, the upper pressing die 3 comprises an upper die shell 31, two placing grooves are symmetrically arranged on both sides of the upper pressing die 3, and two cleaning assemblies 4 are respectively arranged in the inner portions of the two placing grooves;

[0040] The cleaning assembly 4 comprises a fixed pipe 41, a piston block 42, a pushing rod 43 and a cleaning strip 44, the fixed pipe 41 is fixedly connected to the side edge of the upper die shell 31, the piston block 42 is sealingly and slidingly arranged in the fixed pipe 41, a sliding opening is formed in the side wall of the upper die shell 31, the pushing rod 43 is fixedly connected to the piston block 42 and slidingly arranged in the sliding opening, and the cleaning strip 44 is vertically and fixedly connected to the end portion of the pushing rod 43 and arranged in the placing groove;

[0041] The upper pressing die 3 is provided with a hydraulic adjusting assembly 5, and the hydraulic adjusting assembly 5 is used for adjusting the position of the piston block 42 in the fixed pipe 41.

[0042] In the embodiment of the application, during casting, the metal liquid may seep into the micro-holes of the mold or the demolding slope is insufficient or the ejection is unbalanced, which may cause local tearing of the casting, and metal residues may be left in the inner part of the upper mold shell 31. If the residues are not cleaned in time, pits may be formed on the surface of the casting during the next casting, which affects the forming of the casting.

[0043] After the casting is completed, the hydraulic adjusting assembly 5 pushes the piston block 42, so that the piston block 42 moves in the fixed pipe 41, thereby driving the push rod 43 and the cleaning strip 44 to move. During the movement of the cleaning strips 44 on the two sides, the inner wall of the upper mold shell 31 is scraped and cleaned. During the movement of the cleaning strip 44, the demolding effect of separating the casting from the upper mold shell 31 is achieved, and the residues generated are scraped and cleaned.

[0044] The application can push the casting out from both sides during demolding, which reduces the extrusion deformation of the casting, and can also remove the metal residues in the mold.

[0045] The preferred technical solutions in the embodiment are as follows:

[0046] With reference to Figure 3 The upper pressing mold 3 further comprises two hydraulic columns 32 and a connecting plate 33. The two hydraulic columns 32 are vertically and fixedly connected to the upper part of the casting frame 1. The connecting plate 33 is slidably arranged at the four corners of the casting frame 1. The bottom end of the hydraulic column 32 is fixedly connected to the upper surface of the connecting plate 33. The upper mold shell 31 is movably arranged below the connecting plate 33.

[0047] During casting, one hydraulic column 32 drives the connecting plate 33 and the upper mold shell 31 to move downward. After the upper mold shell 31 is combined with the lower guide bottom mold 2, the material tank is pressurized, the molten metal is smoothly injected into the mold cavity through the pipe of the guide bottom mold 2 under low pressure, the process is similar to low-pressure casting, and turbulence and air entrainment are avoided. During casting, when the metal liquid is filled by more than 95%, another hydraulic column 32 is controlled to drive the upper mold shell 31 to move downward to extrude the un-solidified metal under super-high pressure, so as to accelerate the solidification and forming of the metal liquid.

[0048] With reference to Figures 5-6 The upper pressing mold 3 is symmetrically provided with two ejection assemblies 9. The ejection assembly 9 comprises a push rod 91 and an ejection plate 92. Two push ports are vertically and symmetrically arranged on the connecting plate 33 and the upper mold shell 31. A clamping groove is arranged below the push port. The push rod 91 is sealingly and slidably arranged in the push port. The ejection plate 92 is fixedly connected to the bottom end of the push rod 91 and clamped in the clamping groove.

[0049] After the casting is finished, in order to ensure that the two cleaning assemblies 4 can be inserted into the gap between the casting and the upper mold shell 31, the pushing rod 91 is quickly pushed by the hydraulic adjusting assembly 5 after the casting is finished, so that the ejection plate 92 pushes the two sides of the casting, and after the ejection is completed, the ejection plate 92 is reset, so that a gap is formed between the casting and the upper mold shell 31, thereby facilitating the insertion of the cleaning strip 44 into the casting and the inside of the upper mold shell 31.

[0050] The ejection plate 92 arranged on the two sides of the casting can ensure the ejection of the casting while reducing the ejection deformation of the casting by increasing the contact area.

[0051] With reference to Figures 5-6 The hydraulic adjusting assembly 5 comprises a mounting pipe 51, a hydraulic rod 52, a communication pipe 53 and a control pipe 54, the mounting pipe 51 is mounted on the connecting plate 33, the hydraulic rod 52 is telescopic at both ends and is arranged in the mounting pipe 51, the communication pipe 53 is communicated between the mounting pipe 51 and the fixed pipe 41, and the control pipe 54 is fixedly connected between the pushing port and the mounting pipe 51.

[0052] During the position adjustment of the cleaning assembly 4, the hydraulic rod 52 is in a retracted state during feeding, so that the hydraulic oil in the fixed pipe 41 is drawn into the mounting pipe 51, when the casting is finished and demolding is needed, the hydraulic rod 52 is controlled to push the hydraulic oil in the mounting pipe 51, so that the hydraulic oil is introduced into the fixed pipe 41 through the communication pipe 53, the sealing block 64 is pushed, and the pushing rod 43 and the cleaning strip 44 are moved by the sealing block 64.

[0053] Since the hydraulic rod 52 is telescopic at both ends, the cleaning assembly 4 and the ejection assembly 9 can be controlled, the hydraulic oil is extruded by the other hydraulic rod 52, so that the position of the pushing rod 91 is adjusted and controlled.

[0054] The movement distance of the cleaning assembly 4 and the extrusion force provided for the ejection assembly 9 can be controlled by hydraulic adjustment, and the same hydraulic adjusting assembly 5 is controlled at the same time, which reduces the setting of the control equipment, and the hydraulic adjusting assembly 5 is convenient to disassemble and maintain.

[0055] With reference to Figures 6-8 The side of the cleaning strip 44 away from the pushing rod 43 is provided with an inclined edge, and the upper side of the inclined edge is outwardly convex, forming a triangular cleaning edge.

[0056] In order to clean the metal residues adhered to the inside of the upper mold shell 31, the top of the upper mold shell 31 is scraped from both sides to the middle by two cleaning strips 44 on both sides. The triangular cleaning strip 44 side can conveniently shovel the solidified residues quickly. The cleaning strip 44 cleans the residues while assisting in demolding, thereby ensuring the cleanliness of the inside of the upper mold shell 31 and avoiding the influence of the residues on the subsequent casting forming.

[0057] At the same time, the triangular side cleaning strip 44 can separate the side of the casting from the upper mold shell 31, thereby reducing the hard extrusion area between the cleaning strip 44 and the casting, thereby ensuring that the upper surface of the casting will not be deformed during demolding, and improving the integrity of the casting.

[0058] Referring to Figure 8 The fixed pipe 41 is provided with a ventilation assembly 6 for venting the inside of the upper mold 3 during demolding.

[0059] The ventilation assembly includes a ventilation pipe 61, a plurality of inner air ports 62, a gas guide channel 63, a sealing block 64, and a plurality of air outlets 65. The ventilation pipe 61 is fixedly connected to the side of the fixed pipe 41 close to the upper mold 3. The gas guide channel 63 is T-shaped and is arranged between the push rod 43 and the cleaning strip 44. The sealing block 64 is fixedly connected in the gas guide channel 63. The push rod 43 is slidingly arranged on the sealing block 64. A plurality of inner air ports 62 are annularly arranged on the side of the push rod 43 close to the sealing block 64 and are in communication with the gas guide channel 63. A plurality of air outlets 65 are arranged on the cleaning edge of the cleaning strip 44.

[0060] During demolding, due to the adhesion between the casting and the upper mold shell 31, in order to improve the demolding efficiency, the ventilation demolding can be selected to quickly guide the gas into the gap between the casting and the upper mold shell 31, thereby completing the rapid demolding of the casting.

[0061] The piston block 42 in the cleaning assembly 4 will divide the fixed tube 41 into two parts, and the hydraulic cavity is arranged on the side close to the hydraulic adjusting assembly 5, and then the gas cavity space is formed between the piston block 42 and the sealing block 64 on the other side. When the piston block 42 is pushed by the hydraulic pressure of the hydraulic adjusting assembly 5, the piston block 42 will extrude the gas in the gas cavity space, and the gas is introduced into the gas guide channel 63 through the plurality of inner gas ports 62, and then the gas is uniformly sprayed into the gap between the upper mold shell 31 and the casting through the plurality of gas outlets 65. At the same time, due to the setting of the diameter of the fixed tube 41, a large amount of gas will be sprayed out during the movement of the piston block 42, so that a large amount of gas is accumulated in the gap between the upper mold shell 31 and the casting, and the upper mold shell 31 and the casting are separated by the continuously increasing gas pressure. During the air separation process, the moving cleaning strip 44 can quickly transfer the sprayed gas to the newly generated gap, and the cleaning strip 44 can also scrape and separate the adhered metal residues.

[0062] When the demolding is completed, the mold is closed again for casting. At this time, the piston block 42 is driven to move by the hydraulic control assembly, so that the cleaning strip 44 moves from the middle of the upper mold shell 31 to both sides. During the movement, the residual gas in the mold is quickly extracted through the gas outlet 65, so that a vacuum is formed in the mold to avoid the formation of casting bubbles in the casting.

[0063] During the air demolding and mold gas extraction process, the air connection pipe 61 can be connected with the vacuum pump and the inert gas pump according to the use condition. During the gas extraction process, the gas in the mold can be extracted by the auxiliary vacuum pump. During the air demolding process, if the volume of the gas in the fixed tube 41 is not enough, the inert gas can be introduced into the fixed tube 41 through the inert gas pump, so as to complete the air demolding of castings with different volumes.

[0064] Referring to Figure 9 , the placing groove is provided below the slot of the deflection groove, and the opening and closing assembly 7 is arranged in the deflection groove, which is used to control the opening and closing of the slot of the deflection groove.

[0065] The opening and closing assembly 7 comprises an elastic connecting rod 71 and an opening and closing plate 72, the elastic connecting rod 71 is fixedly connected in the deflection groove, and the opening and closing plate 72 is fixedly connected to the side edge of the elastic connecting rod 71.

[0066] In order to avoid the metal liquid into the placement groove on both sides of the upper mold shell 31 when the metal liquid is introduced, affecting the normal work of the cleaning assembly 4, a deflection groove is arranged below the placement groove, a one-way deflection opening and closing assembly 7 is arranged in the deflection groove, the opening and closing plate 72 is fixed in the slot of the placement groove through the elastic connecting rod 71, the elastic connecting rod 71 is made of high-temperature resistant material, and two spring shafts are arranged on both sides for controlling the elastic rotation of the elastic connecting rod 71.

[0067] When the cleaning assembly 4 is retracted into the placement groove, the opening and closing plate 72 is reset under the elastic action of the elastic connecting rod 71, so as to one-way close the placement groove, avoiding the metal liquid into the placement groove during the material guiding process, when demolding and cleaning, the cleaning assembly 4 moves outwards, the cleaning strip 44 pushes the opening and closing plate 72, so that the opening and closing plate 72 deflects outwardly, the slot of the placement groove is opened, the cleaning strip 44 moves outwards, demolding and cleaning are carried out, and the opening and closing plate 72 is reset again after cleaning.

[0068] Referring to Figure 9 , the opening and closing plate 72 is provided with a scraping strip 8 close to one side of the cleaning assembly 4, the scraping strip 8 is fixedly connected to the middle part of the opening and closing plate 72 and is arranged obliquely upwards to form a y shape with the opening and closing plate 72, and the end of the scraping strip 8 is arranged to be inclined to the cleaning strip 44;

[0069] The placement groove is provided with a guide outlet 10 close to one side of the deflection groove, the guide outlet 10 is arranged below the scraping strip 8, and a sealing strip is arranged below the guide outlet 10.

[0070] Since part of the metal residues will adhere to the cleaning strip 44 during the cleaning of the metal residues, in order to avoid the metal residues from blocking the air outlet 65, the cleaning strip 44 is in contact with the scraping strip 8 during the outward movement of the cleaning strip 44 from the placement groove, the inclined side of the cleaning strip 44 is scraped by the scraping strip 8, the scraped residues are transferred to the guide outlet 10 for accumulation, and the guide outlet 10 is cleaned regularly by opening the sealing strip, so that the accumulation of metal residues is reduced.

[0071] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
