Description

Technical Field

[0001] The invention relates to the technical field of die casting, in particular to a molding device for facilitating demoulding of aluminum die castings. Background Art

[0002] A die-casting mold is a mold used for die-casting molten metal. It can cool the molten metal into a desired shape. When producing die-casting parts, the metal is first heated and melted into molten metal, and then the molten metal is filled into the mold cavity, and the die-casting part is solidified under high pressure. Traditional die-casting molds are mainly aluminum die-casting molds for forming aluminum products.

[0003] After the die-casting is completed, the formed die-casting is stuck inside the mold and requires a certain amount of thrust to separate the die-casting from the mold. Since a part of the raw material will remain on one side of the die-casting and connected to the feed port of the mold, one side of the die-casting will need to be polished later, which will affect the next die-casting work.

[0004] Therefore, it is necessary to provide a molding device that facilitates the demoulding of aluminum die castings to solve the above technical problems. Summary of the invention

[0005] The purpose of the present invention is to provide a molding device that facilitates the demolding of aluminum die-casting parts to solve the problems existing in the above-mentioned background technology. The technical solution of the present invention provides a solution that is significantly different from the prior art in order to solve the technical problem that the prior art solution is too single.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a molding device that facilitates the demolding of aluminum die-casting parts, comprising a fixed seat, grooves are provided at both ends of the fixed seat, a fixed mold with an adjustable position is arranged inside the groove, movable rods are arranged through the four corners of the interior of the fixed seat, movable molds are installed at both ends of the movable rods, an extrusion mechanism that facilitates demolding is arranged inside the movable mold, a transportation hole is provided at the center of the two ends of the interior of the fixed seat, and a discharge hole is connected to one side of the top of the transportation hole and penetrates to the top of the fixed seat.

[0007] Preferably, a fixed plate is installed at the center of the front and rear ends of the fixed seat, both ends of the fixed plate are connected to spring 1, the other end of the spring 1 is connected to a movable plate, and slots are provided on both sides of the front and rear ends of the fixed seat, and a connecting plate connected to the fixed mold end is provided inside the slot, and the connecting plate is fixedly connected to the movable plate.

[0008] Preferably, a central groove is provided between the two groups of the transport holes, electric push rods are mounted at both ends of the central groove, and the telescopic ends of the electric push rods are arranged to cooperate with the transport holes.

[0009] Preferably, a connecting hole cooperating with the transport hole is opened at the center of the fixed mold, a circular ring plate is arranged on one side of the inner part of the connecting hole, and a circular plate is rotatably connected to the inner part of the circular ring plate.

[0010] Preferably, a movable groove is provided at the upper and lower ends of the communicating hole, and a movable block fixed to the upper and lower ends of the circular ring plate is provided inside the movable groove.

[0011] Preferably, the movable groove is connected to an inner groove at one end away from the connecting hole, a second spring is installed on the side of the inner groove away from the fixed seat, and the other end of the second spring is connected to a fixed block fixed on the outside of the movable block.

[0012] Preferably, the extrusion mechanism includes an arc-shaped channel 1 opened on both sides of the movable mold near the center and an arc-shaped channel 2 opened on both sides away from the center, a piston rod 1 penetrating one side of the movable mold is arranged on the inner side of the longer end of the arc-shaped channel 1, a piston rod 2 penetrating one side of the movable mold is arranged on the inner side of the longer end of the arc-shaped channel 2, a spring 3 fixed on the inner side of the arc-shaped channel 1 is connected to the side of the piston rod 1 away from the fixed mold, and U-shaped blocks are arranged on the inner sides of the shorter ends of the arc-shaped channel 1 and the arc-shaped channel 2.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention is connected to one side of a group of movable molds through a driving member in the prior art, and controls the movable mold to move toward the direction of the fixed seat and move away through the driving member. When the movable mold on one side is controlled to move toward the direction of the fixed seat, the movable rod drives the other group of movable molds to move away from the fixed seat, and the movable mold moving toward the fixed seat squeezes the fixed mold at the corresponding position to move toward the groove direction, thereby compressing the spring 1 until the fixed mold moves into the groove, thereby realizing the staggered work between the two groups of movable molds and the fixed mold, realizing the continuous die-casting work of the double-stations taking over each other, and improving the work efficiency; The aluminum liquid pushed by the present invention will enter the mold cavity formed by the fixed mold and the movable mold through the connecting hole for molding. The circular plate can be rotated inside the circular ring plate, so that the aluminum liquid will rotate the circular plate out of position during transportation and pass through the circular ring plate. When the aluminum liquid is molded into a solid state, the circular plate will disconnect the aluminum liquid on both sides, so that when the demolding work is performed, the solid structure formed by the aluminum liquid on the side of the circular plate facing the fixed seat is separated from the molded die casting, thereby reducing the intensity of subsequent grinding work. When the present invention is demoulded after the molding is completed, the fixed mold will move in the direction away from the fixed seat. At this time, the second spring is reset so that the movable block moves toward the fixed seat again, and the circular plate is controlled to move toward the fixed seat, so that the solid waste on one side of the circular plate can be squeezed out from the inside of the connecting hole, so as not to affect the next die-casting work. During the molding process of the present invention, the movable mold will move toward the fixed mold, and will drive the piston rod 2 to move toward the inner side of the arc channel 2, so that it is completely immersed in the arc channel 2. At this time, the oil will be pushed to drive the U-shaped block to move toward the fixed seat, so that negative pressure is formed inside the arc channel 1, driving the piston rod 1 to move toward the inside of the arc channel 1 to compress the spring 3. After the molding is completed, the movable mold and the fixed mold will be separated. At this time, the molded die-casting will be stuck on the movable mold. At this time, the piston rod 1 and the piston rod 2 are reset by the elastic force of the spring 3. At this time, the die-casting will be automatically squeezed out during the reset process of the piston rod 1. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] like Figure 1-7 As shown, a fixed plate 9 is installed at the front and rear end centers of the fixed seat 1, and springs 10 are connected to both ends of the fixed plate 9, and a movable plate 11 is connected to the other end of the spring 10. Slots 12 are provided on both sides of the front and rear ends of the fixed seat 1, and a connecting plate 13 connected to the end of the fixed mold 3 is provided inside the slot 12, and the connecting plate 13 is fixedly connected to the movable plate 11, and is connected to one side of a group of movable molds 5 through a driving member in the prior art, and the movable mold 5 is controlled by the driving member to move toward the direction of the fixed seat 1 to move away, and when the movable mold 5 on one side is controlled to move toward the fixed seat 1, the movable rod 4 will drive the other group of movable molds 5 away from the fixed seat 1, and the movable mold 5 moving toward the fixed seat 1 will squeeze the fixed mold 3 at the corresponding position to move toward the groove 2, thereby compressing the spring 10 until the fixed mold 3 moves into the groove 2, thereby realizing the staggered work between the two groups of movable molds 5 and the fixed mold 3, realizing the continuous die-casting work of the double stations taking over each other, and improving the work efficiency.

[0020] like Figure 1-7 As shown, a central groove 701 is opened between the two groups of transport holes 7, and electric push rods 702 are installed at both ends of the central groove 701, and the telescopic ends of the electric push rods 702 are matched with the transport holes 7. When the fixed mold 3 at the corresponding position moves to the inside of the groove 2, the aluminum liquid is injected into the inside of the transport hole 7 from the discharge hole 8 at the corresponding position, and then the aluminum liquid is pushed to move toward the direction of the fixed mold 3 by driving the electric push rod 702 at the corresponding position. A one-way valve is arranged on the outer wall of the discharge hole 8, so that the aluminum liquid can only enter the fixed mold 3 for die-casting.

[0021] like Figure 1-7 As shown, a connecting hole 14 cooperating with the transport hole 7 is opened at the center of the fixed mold 3, and a circular plate 15 is arranged on one side of the inner part of the connecting hole 14. The inner part of the circular plate 15 is rotatably connected with a circular plate 16. The pushed aluminum liquid will enter the mold cavity formed by the fixed mold 3 and the movable mold 5 through the connecting hole 14 for molding. The circular plate 16 can be rotated inside the circular plate 15, so that the aluminum liquid will rotate the circular plate 16 out of position during transportation and pass through the circular plate 15. When the aluminum liquid is molded into a solid state, the circular plate 16 will disconnect the aluminum liquid on both sides, so that when the demolding work is performed, the solid structure formed by the aluminum liquid on the side of the circular plate 16 facing the fixed seat 1 is separated from the molded die-casting.

[0022] like Figure 1-7 As shown, the upper and lower ends of the connecting hole 14 are connected to each other with a movable groove 17, and the interior of the movable groove 17 is provided with movable blocks 18 fixed to the upper and lower ends of the circular plate 15.

[0023] like Figure 1-7 As shown, the end of the movable groove 17 away from the connecting hole 14 is connected to the inner groove 19, and the side of the inner groove 19 away from the fixed seat 1 is installed with a spring 20, and the other end of the spring 20 is connected to a fixed block 21 fixed on the outside of the movable block 18. When the molding work is carried out, the fixed mold 3 at the corresponding position will move to the inside of the groove 2, thereby squeezing the movable block 18 extending from the outside of the fixed mold 3 into the inside of the connecting hole 14. In this process, the spring 20 will be squeezed and compressed. When demolding is performed after the molding is completed, the fixed mold 3 will move in the direction away from the fixed seat 1. At this time, the spring 20 is reset so that the movable block 18 moves back to the direction of the fixed seat 1.

[0024] like Figure 1-7As shown, the extrusion mechanism 6 includes an arc channel 1 601 opened on both sides of the center of the movable mold 5 and an arc channel 2 602 opened on both sides of the center. A piston rod 1 603 penetrating one side of the movable mold 5 is arranged on the inner side of the longer end of the arc channel 1 601, and a piston rod 2 604 penetrating one side of the movable mold 5 is arranged on the inner side of the longer end of the arc channel 2 602. A spring 3 605 fixed on the inner side of the arc channel 1 601 is connected to the side of the piston rod 1 603 away from the fixed mold 3. A U-shaped block 606 is arranged on the inner side of the shorter ends of the arc channel 1 601 and the arc channel 2 602. During the molding process, the movable mold 5 moves toward the fixed mold 3. It will drive the piston rod 2 604 to move toward the inside of the arc channel 2 602, so that it is completely immersed in the arc channel 2 602. At this time, it will push the oil to drive the U-shaped block 606 to move toward the fixed seat 1, so that negative pressure is formed inside the arc channel 1 601, driving the piston rod 1 603 to move toward the inside of the arc channel 1 601 to compress the spring 3 605. After the molding is completed, the movable mold 5 and the fixed mold 3 will be separated. At this time, the molded die-casting will be stuck on the movable mold 5. At this time, the piston rod 1 603 and the piston rod 2 604 are reset by the elastic force of the spring 3 605. At this time, the die-casting will be automatically squeezed out during the reset process of the piston rod 1 603.

[0025] Working principle: When in use, a driving member in the prior art is connected to one side of a group of movable molds 5, and the driving member controls the movable mold 5 to move closer to and away from the fixed seat 1. When the movable mold 5 on one side is controlled to move toward the fixed seat 1, the movable rod 4 will drive the other group of movable molds 5 away from the fixed seat 1, and the movable mold 5 moving toward the fixed seat 1 will squeeze the fixed mold 3 at the corresponding position to move toward the groove 2, thereby compressing the spring 10 until the fixed mold 3 moves into the groove 2, thereby realizing the staggered work between the two groups of movable molds 5 and the fixed mold 3, realizing the continuous die-casting work of the double-station succession, and speeding up the work efficiency. When the fixed mold 3 at the corresponding position moves to the inside of the groove 2, the aluminum liquid is then The discharge hole 8 at the corresponding position is injected into the transport hole 7, and then the electric push rod 702 at the corresponding position is driven to push the aluminum liquid toward the fixed mold 3. A one-way valve is arranged on the outer wall of the discharge hole 8, so that the aluminum liquid can only enter the fixed mold 3 for die-casting. The pushed aluminum liquid will enter the mold cavity composed of the fixed mold 3 and the movable mold 5 through the connecting hole 14 for molding. The circular plate 16 can be rotated inside the annular plate 15, so that the aluminum liquid will rotate the circular plate 16 out of position during transportation and pass through the annular plate 15. When the aluminum liquid is formed into a solid state, the circular plate 16 will disconnect the aluminum liquid on both sides, so that the circular plate 16 faces the fixed seat when the demolding work is performed. 1 is separated from the die-casting after forming. When the forming work is carried out, the fixed die 3 at the corresponding position will move into the groove 2, thereby squeezing the movable block 18 extending from the outside of the fixed die 3 into the connecting hole 14. In this process, the spring 20 will be squeezed for compression. When demoulding is performed after the forming is completed, the fixed die 3 will move in the direction away from the fixed seat 1. At this time, the spring 20 will be reset so that the movable block 18 will move toward the fixed seat 1 again, and the circular plate 16 will be controlled to move toward the fixed seat 1. The solid waste on one side of the circular plate 16 can be squeezed out from the connecting hole 14, so as not to affect the next die-casting work. In the forming process, the movable block 18 will be squeezed out from the connecting hole 14. During the movement of the mold 5 toward the fixed mold 3, the piston rod 2 604 will be driven to move toward the inner side of the arc channel 2 602, so that it is completely immersed in the arc channel 2 602. At this time, the oil will be pushed to drive the U-shaped block 606 to move toward the fixed seat 1, so that negative pressure is formed inside the arc channel 1 601, driving the piston rod 1 603 to move toward the inside of the arc channel 1 601 to compress the spring 3 605. After the molding is completed, the movable mold 5 and the fixed mold 3 will be separated. At this time, the molded die-casting will be stuck on the movable mold 5. At this time, the piston rod 1 603 and the piston rod 2 604 are reset by the elastic force of the spring 3 605. At this time, the die-casting will be automatically squeezed out during the reset of the piston rod 1 603.
