Description

Technical Field

[0001] The invention belongs to the technical field of molding equipment, and in particular relates to a high-pressure casting molding machine for nonferrous metals. Background Art

[0002] Casting has the advantages of fast production speed, high efficiency and precise product size. It is widely used in the manufacturing fields of automobiles, plastic products, machinery, and aerospace. Casting is a cyclic process. Each cycle mainly includes quantitative feeding, melting and plasticization, pressure injection, mold filling and cooling, and mold opening and taking out the parts. After taking out the plastic parts, the mold is closed again for the next cycle.

[0003] In the actual production application of magnesium alloys and aluminum alloys, in order to make it easier to demold the products after molding and to improve the molding quality of the products, it is necessary to spray the mold cavity and the die outlet with a mold release agent. After the high-pressure casting molding machine has cast a product, it is usually necessary to manually spray the mold cavity and the die outlet with the mold release agent, which is time-consuming and labor-intensive. In response to the above technical problems, a Chinese patent with patent announcement number CN208195605U, when in use, uses a manipulator assembly for spraying products and a driving mechanism for driving the manipulator assembly to move, so that there is no need to manually spray the mold cavity and the die outlet with a mold release agent. However, since the mold release agent is in an open state when spraying, the mold release agent will escape into the outside air during spraying, and the flow of outside air will cause problems in the flow direction of the mold release agent, resulting in the inability to completely spray the mold cavity and the die outlet with the mold release agent, which can easily cause defects on the surface of the casting after demolding. Summary of the invention

[0008] Further technical solution: two groups of partitions are fixedly installed in the closed frame, the two groups of partitions are symmetrically distributed on both sides of the mounting frame and the mounting plate is located between the two groups of partitions, and multiple groups of evenly distributed through grooves are opened on the partitions, and the positions of the through grooves correspond one by one to the positions of the mounting plates.

[0009] Further technical solution: a vertical plate located on both sides of the through groove is fixedly installed on the surface of the partition away from the mounting plate, and multiple groups of second guide columns are slidably installed on the vertical plates, and a baffle is commonly fixedly installed on one end of the multiple groups of second guide columns close to the corresponding through grooves, and a second elastic member distributed around the second guide column is fixedly installed on the vertical plate, and the end of the second elastic member away from the vertical plate is fixedly connected to the baffle, and a slope structure is provided on the side of the baffle away from the vertical plate. In the initial state, the two groups of baffles are in contact with each other and the V-shaped opening formed faces the through groove.

[0010] Further technical solution: A telescopic member is fixedly installed on the inner bottom surface of the closed frame, and two sets of power plates are rotatably installed on the output end of the telescopic member. The end of the power plate away from the telescopic member is rotatably connected to the horizontal plate on the corresponding side, and the baffle is pushed to move when the horizontal plate moves outward.

[0011] Further technical solution: Push plates are fixedly installed at both ends of the mounting plate, and the end of the push plate away from the mounting plate is a V-shaped structure. The push plate is used in conjunction with a roller rotatably installed on the baffle.

[0012] Further technical solution: connecting boxes are fixedly installed on the upper and lower surfaces of the closed frame, and a through hole connected to the connecting box is opened on the side wall of the closed frame, and the through hole is located on the outside of the partition.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. After the material is unloaded, the closed frame is driven to move by the control component. When the closed frame is aligned with the molding cavity and the die outlet, it stops. At this time, the molding cavity moves to one side of the die outlet table and presses the closed frame on the die outlet table. The die outlet, the molding cavity and the closed frame can form a sealed area. The release agent is sprayed onto the inner wall of the die outlet and the molding cavity through the nozzle, which avoids the release agent from escaping into the surrounding air during spraying and the influence of external air flow on the spraying of the release agent, ensuring that the release agent can be completely sprayed onto the inner wall of the die outlet and the molding cavity, thereby improving the demoulding quality of the casting.

[0016] 2. The partition and baffle can be used to seal the area where the nozzle is located to avoid dust accumulation on the nozzle when not in use. At the same time, the partition and baffle can reduce the area in contact with the outside air in the closed frame, thereby reducing the probability of dust remaining in the molding cavity and the die outlet when the release agent is sprayed later, further improving the quality of the casting.

[0017] 3. The air in the lower connecting box is extracted by an air pump, and the extracted air is filtered and transported to the upper connecting box through a reflux pipe. The air in the upper connecting box enters the sealed areas on both sides through the upper through holes, thereby realizing the self-circulation of air in the sealed areas on both sides. During the flow of air, the internal areas of the closed frame, the die outlet, and the molding cavity are cleaned. Dust and impurities follow the air into the filter chamber for filtration and collection, thereby ensuring the cleanliness of the closed frame, the die outlet, and the molding cavity, ensuring that the die outlet and the inner wall of the molding cavity can be evenly sprayed with a release agent, reducing the influence of dust in the closed frame, the die outlet, and the molding cavity on the quality of castings, and further improving the quality of castings.

[0018] 4. After the release agent is sprayed, open the air pump, the second branch pipe and the solenoid valve on the air inlet pipe. At this time, the air pump extracts the air in the sealed areas on both sides and transports it to the external equipment through the second branch pipe for purification. The outside air is filtered by the filter and then replenished from the air inlet pipe to the sealed areas on both sides. After the set time, the air in the sealed areas on both sides is completely replaced by the outside air. The release agent floating in the air in the sealed area is extracted with the air, thereby preventing the release agent in the air from escaping to the outside after the closed frame is separated, and preventing the staff from inhaling and affecting their health. At the same time, when the air flows in the sealed area, it can accelerate the drying of the release agent on the inner wall of the die outlet and the molding cavity, improve the effect of forming a film on the inner wall of the die outlet and the molding cavity, and avoid defects on the casting surface caused by insufficiently dried release agent, affecting product quality.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0031] like Figure 1-Figure 2As shown, a high-pressure casting molding machine for non-ferrous metals provided by the present invention includes a machine body 1, a demolding platform 2 is arranged on the machine body 1, a molding cavity 3 is arranged on the demolding platform 2, and a demolding port 4 is arranged on the side of the demolding platform 2 close to the molding cavity 3, a bracket 5 is fixedly installed on the side of the demolding platform 2, a closing frame 13 is arranged on the bracket 5, and a control component 37 for adjusting the position of the closing frame 13 is arranged on the bracket 5, two groups of mounting frames 35 are fixedly installed on the inner bottom surface of the closing frame 13, two groups of cross plates 28 are slidably installed on the horizontal section of the mounting frame 35, a plurality of groups of evenly distributed mounting plates 29 are fixedly installed on the cross plates 28, a plurality of groups of nozzles 30 are fixedly installed on the surface of the mounting plate 29 away from the cross plates 28, and the nozzles 30 are connected to a material pump 34 fixedly installed on the outer side of the closing frame 13.

[0032] In actual application of this embodiment, the forming mold cavity 3 contacts the die outlet 4 to form a mold cavity for casting. After the casting is completed, the forming mold cavity 3 moves away from the die outlet 2 for unloading. After the unloading is completed, the closing frame 13 is driven to move by the control component 37. When the closing frame 13 is aligned with the forming mold cavity 3 and the die outlet 4, it stops. At this time, the forming mold cavity 3 moves to one side of the die outlet 2 and presses the closing frame 13 on the die outlet 2. The die outlet 4, the forming mold cavity 3 and the closing frame 13 can form a sealing area, and the material pump 34 is used to spray The head 30 delivers the release agent, which is sprayed onto the die outlet 4 and the inner wall of the molding cavity 3 through the nozzle 30, thereby preventing the release agent from escaping into the surrounding air during spraying and preventing the influence of external air flow on the spraying of the release agent, thereby ensuring that the release agent can be completely sprayed onto the die outlet 4 and the inner wall of the molding cavity 3, thereby improving the demoulding quality of the casting. After the spraying is completed, the molding cavity 3 contacts the fixing of the closing frame 13 to reset the closing frame 13, and then the molding cavity 3 contacts the die outlet 4 to continue casting.

[0033] like Figure 1-Figure 2 As shown, a high-pressure casting machine for nonferrous metals provided by the present invention, the control component 37 includes a servo module 8, the servo module 8 is arranged on the bracket 5 and the servo module 8 drives the movable plate 7 to move, and a plurality of groups of first guide columns 6 are fixedly installed on the vertical section of the bracket 5, the first guide columns 6 penetrate the movable plate 7 and are slidably connected to the movable plate 7, and the end of the first guide column 6 away from the bracket 5 is fixedly connected to the demolding platform 2.

[0034] Specifically, a plurality of groups of parallelly distributed pillars 9 are fixedly installed on the movable plate 7, a support plate 10 is slidably installed on the pillars 9, the support plate 10 is fixedly connected to the closed frame 13, a fixed plate 11 is commonly fixedly installed on the two groups of pillars 9, a first elastic member 12 distributed around the pillars 9 is fixedly installed on the fixed plate 11, and the first elastic member 12 is fixedly connected to the support plate 10 at one end away from the fixed plate 11.

[0035] In actual application of this embodiment, when the material is formed and removed, the servo module 8 drives the moving plate 7 to move toward the direction close to the ejection platform 2, and the moving plate 7 drives the closing frame 13 to move between the ejection platform 2 and the forming cavity 3 through the support 9 and the support plate 10, and stops moving when the closing frame 13 is aligned with the ejection port 4 and the forming cavity 3;

[0036] When the subsequent molding cavity 3 is reset, it contacts with the closing frame 13 and pushes the closing frame 13 to move. When the closing frame 13 contacts the mold outlet 4, it stops. At this time, the closing frame 13, the mold outlet 4 and the molding cavity 3 can form a closed area, and then the demolding agent can be sprayed. When the closing frame 13 moves, it will compress the first elastic member 12. After the subsequent demolding agent is sprayed, the molding cavity 3 moves away from the mold platform 2 again. Under the action of the first elastic member 12, the closing frame 13 is separated from the contact with the mold outlet 4, and then the moving plate 7 can drive the closing frame 13 to reset. When the closing frame 13 moves along the length direction of the first guide column 6, it will not rub against the mold outlet 4 and the molding cavity 3. The movement of the closing frame 13 in the length direction of the pillar 9 enables the molding cavity 3 to press the closing frame 13 against the mold outlet 4, thereby ensuring the sealing of the closed area formed by the closing frame 13, the mold outlet 4 and the molding cavity 3.

[0037] In an embodiment of the present invention, the first elastic member 12 is a first spring, and can also be other elastic members such as an elastic ball. The first spring is compressed to provide a resetting thrust to the closing frame 13 .

[0038] like Figure 1-Figure 9 As shown, a high-pressure casting machine for nonferrous metals provided by the present invention is provided, wherein two groups of partitions 21 are fixedly installed in the closed frame 13, the two groups of partitions 21 are symmetrically distributed on both sides of the mounting frame 35, and the mounting plate 29 is located between the two groups of partitions 21, and a plurality of groups of evenly distributed through grooves 22 are provided on the partitions 21, and the positions of the through grooves 22 correspond one-to-one to the positions of the mounting plates 29.

[0039] Specifically, vertical plates 26 located on both sides of the through slot 22 are fixedly installed on the surface of the partition 21 away from the mounting plate 29, multiple groups of second guide columns 24 are slidably installed on the vertical plates 26, and baffles 23 are commonly fixedly installed on one end of the multiple groups of second guide columns 24 close to the corresponding through slot 22. Second elastic members 25 distributed around the second guide columns 24 are fixedly installed on the vertical plates 26, and one end of the second elastic member 25 away from the vertical plates 26 is fixedly connected to the baffle 23. The side of the baffle 23 away from the vertical plates 26 is provided with an inclined structure. In the initial state, the two groups of baffles 23 are in contact with each other and the V-shaped opening formed faces the through slot 22.

[0040] Specifically, a telescopic member 32 is fixedly installed on the inner bottom surface of the closed frame 13, and two sets of power plates 33 are rotatably installed on the output end of the telescopic member 32. The end of the power plate 33 away from the telescopic member 32 is rotatably connected to the horizontal plate 28 on the corresponding side. When the horizontal plate 28 moves outward, it pushes the baffle 23 to move.

[0041] Specifically, push plates 31 are fixedly mounted on both ends of the mounting plate 29 . One end of the push plate 31 away from the mounting plate 29 is a V-shaped structure. The push plate 31 is used in conjunction with a roller 27 rotatably mounted on the baffle 23 .

[0042] In actual application of this embodiment, when it is necessary to spray the release agent, the telescopic member 32 is extended, and the telescopic member 32 pushes the two sets of horizontal plates 28 to move in the direction close to the partition 21 through the power plate 33. At this time, the push plate 31 first contacts the roller 27. As the horizontal plate 28 moves, the push plate 31 and the roller 27 act to move the baffle 23 to both sides and open. When the baffle 23 moves, it compresses the second elastic member 25. When the side of the push plate 31 perpendicular to the mounting plate 29 contacts the roller 27, the baffle 23 is fully opened. At this time, the mounting plate 29 continues to move outward to make the nozzle 3 0 passes over the partition 21. After the release agent is sprayed, the telescopic member 32 shrinks and resets to reset the mounting plate 29. Under the action of the second elastic member 25, the baffle 23 is reset to cover the through groove 22. The partition 21 and the baffle 23 can be used to close the area where the nozzle 30 is located to avoid dust accumulation on the nozzle 30 when not in use. At the same time, the partition 21 and the baffle 23 reduce the area in contact with the outside air in the closed frame 13, thereby reducing the probability of dust remaining in the molding cavity 3 and the die outlet 4 when the release agent is sprayed later, thereby further improving the quality of the casting.

[0043] In one embodiment of the present invention, the second elastic member 25 is a second spring, and of course it can also be other elastic members such as an elastic ball. The second spring is compressed to provide a reset thrust to the baffle 23. The telescopic member 32 is an electric telescopic rod, and of course it can also be other members such as a hydraulic cylinder that can actively change the length. The two sets of horizontal plates 28 are driven to move simultaneously by the extension and contraction of the electric telescopic rod.

[0044] like Figure 1-Figure 9 As shown, a high-pressure casting molding machine for nonferrous metals provided by the present invention, a connecting box 14 is fixedly installed on the upper and lower surfaces of the closed frame 13, a through hole 15 connected to the connecting box 14 is opened on the side wall of the closed frame 13, and the through hole 15 is located on the outside of the partition 21, and an air pump 16 is fixedly installed on the lower connecting box 14, and the air inlet end of the air pump 16 is connected to the lower connecting box 14, and the air pump 16 is connected to a first branch pipe 17 and a second branch pipe 18, and the first branch pipe 17 and the second branch pipe 18 are both provided with solenoid valves, the first branch pipe 17 is connected to a filter chamber 19, and the filter chamber 19 is connected to a reflux pipe 20, and the reflux pipe 20 is connected to the upper connecting box 14.

[0045] Specifically, the connecting box 14 at the top of the closed frame 13 is connected to an air intake pipe 36 , and the air intake pipe 36 is provided with a solenoid valve and a filter.

[0046] In actual application of this embodiment, after the casting closing frame 13, the die outlet 4 and the molding cavity 3 are removed to form a closed area, the area is divided into three areas due to the presence of the partition 21. At this time, the air pump 16 and the electromagnetic valve on the first branch pipe 17 are turned on, and the air pump 16 extracts the air in the lower connecting box 14, so that the air in the closed areas on both sides can be replenished downward to the lower connecting box 14 through the through hole 15, and then transported to the filter chamber 19 through the first branch pipe 17 for filtration. The filtered air is transported to the upper connecting box 14 through the return pipe 20, and the air in the upper connecting box 14 is The air enters the sealed areas on both sides through the through holes 15 at the top, thereby realizing the self-circulation flow of the air in the sealed areas on both sides. During the flow of the air, the internal areas of the closed frame 13, the die outlet 4, and the molding cavity 3 are cleaned, and the dust and impurities follow the air into the filter chamber 19 for filtration and collection, thereby ensuring the cleanliness of the closed frame 13, the die outlet 4, and the molding cavity 3, ensuring that the die outlet 4 and the inner wall of the molding cavity 3 can be evenly sprayed with the release agent, reducing the influence of the dust in the closed frame 13, the die outlet 4, and the molding cavity 3 on the quality of the casting, and further improving the quality of the casting;

[0047] After the cleaning is completed, the air pump 16 and the electromagnetic valve on the first branch pipe 17 are closed to spray the release agent. After the release agent is sprayed, the air pump 16, the second branch pipe 18 and the electromagnetic valve on the air inlet pipe 36 are opened. At this time, the air pump 16 extracts the air in the sealed areas on both sides and transports it to the external equipment through the second branch pipe 18 for purification. The external air is filtered by the filter and replenished from the air inlet pipe 36 to the sealed areas on both sides. After the set time, the air pump 16, the second branch pipe 18 and the electromagnetic valve on the air inlet pipe 36 are closed. The air in the sealed areas on both sides is completely replaced by the external air. The release agent floating in the air in the sealed area is extracted with the air, thereby preventing the release agent in the air from escaping to the outside after the closed frame 13 is separated, and preventing the staff from inhaling and affecting their health. At the same time, when the air flows in the sealed area, it can accelerate the drying of the release agent on the inner wall of the die outlet 4 and the molding cavity 3, improve the effect of forming a film on the inner wall of the die outlet 4 and the molding cavity 3, and avoid the release agent that is not fully dried causing defects on the casting surface, affecting product quality.
