Description

Technical Field

[0001] The present invention belongs to the technical field of metal casting, and specifically relates to an external mold of an open-mold buffer type casting machine. Background Art

[0002] Casting molding, also known as static casting, is to inject the prepared casting raw materials into a mold to solidify them and obtain products similar to the mold cavity. The raw materials for casting molding can be monomers, preliminarily polymerized or polycondensed pastes, or solutions of polymers and monomers, etc. Polymerization or polycondensation reactions usually occur during the solidification process. In recent years, some new casting methods have emerged on the basis of traditional casting molding, including insert molding, centrifugal casting, casting by extrusion, slush molding, rotational molding, etc.

[0003] In the existing casting process, when injecting raw materials, since the raw materials are liquid, during the process of injecting the raw materials into the mold, oxidation with air will cause oxidized impurities inside the finished casting, affecting the purity of the casting. Therefore, the method of sealed feeding is generally used for casting. When using the sealed method for casting, because a corresponding sealed pipe is needed to transport the raw material liquid, it is very easy for liquid to remain inside the sealed pipe. After the pipe body cools, the remaining liquid will form residues, which will then block the inside of the sealed pipe and affect the feeding process. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the present invention provides an external mold of an open-mold buffer type casting machine, which solves the problem that when using the sealed method for casting, because a corresponding sealed pipe is needed to transport the raw material liquid, it is very easy for liquid to remain inside the sealed pipe. After the pipe body cools, the remaining liquid will form residues, which will then block the inside of the sealed pipe and affect the feeding process. Technical Solution

[0005] The technical solution adopted by the present invention to solve its technical problems is as follows: An external mold of an open-mold buffer type casting machine according to the present invention includes a casting machine main body. On the front and rear sides of the outer surface of the casting machine main body, support walls are symmetrically arranged. On the side of the support wall away from the casting machine main body, a feeding device is fixedly connected. Before using this device for casting, molten liquid raw materials are injected into one of the feeding devices, and then the two feeding devices are sealed. The through holes on the lower surface of the hollow strip are connected to the tops of the corresponding material-passing pipes to complete the preparation work.

[0006] Preferably, the casting machine main body includes a fixing plate. Inside the fixing plate, casting cylinders are uniformly arranged through an adapter. The lower surface of the casting cylinder is rotationally connected to a friction drive belt. On the front and rear sides of the inner wall of the friction drive belt, friction rotating cylinders are symmetrically arranged. The lower part of the inner wall of the friction rotating cylinder is rotationally connected to a control motor.

[0007] Preferably, the casting cylinder includes a shaping cylinder. On the left and right sides of the inner wall of the shaping cylinder, material passing pipes are symmetrically arranged. At the center of the lower surface of the shaping cylinder, a control rotating rod is fixedly connected, and an external rotating shaft is fixedly connected to the outer surface of the control rotating rod.

[0008] Preferably, the shaping cylinder includes an external fixed cylinder. At the center of the upper surface of the external fixed cylinder, an upper cover plate is clamped. At the center of the lower surface of the upper cover plate, an upper die cover is fixedly connected. The lower surface of the upper die cover is fixedly connected to a lower template. The molten liquid raw material is injected into the corresponding material passing pipes through a feeding device. The raw material can enter the interior of the shaping cylinder through the material passing pipes. The initial state inside the shaping cylinder is as Figure 4 shown. Therefore, it is necessary to first control the control motors at both ends. The control motors control the friction drive belt to rotate through the friction rotating cylinders, and then control the external rotating shafts below each casting cylinder to rotate by 90 degrees through friction. The outer surface of the upper die cover sweeps across the outer surface of the sealing block. After the sealing chucks on both sides are squeezed, they slide towards the inner wall of the sealing block, and the side springs are compressed to clamp the upper die cover. At this time, the raw material passing through the material passing pipes is injected into the side openings of the upper die cover through the side nozzles to complete the feeding work. During the feeding process of this device, the material is in a relatively sealed state throughout the process and does not come into contact with the air impurities in the outside world. Therefore, it is not easy for oxidation reactions to occur inside the connected and unblocked material passing pipes. Moreover, the two material passing pipes on both sides are responsible for the work of transporting materials and ventilating respectively and will not interfere with each other. Therefore, the residual materials inside the material passing pipes are not easily oxidized into solids to block the inside of the sealing pipes and affect the feeding process.

[0009] Preferably, the external fixed cylinder includes a cylinder shell. On the left and right sides of the inner wall of the cylinder shell, sealing blocks are symmetrically arranged. On both sides of the outer surface of the sealing block, magnetic attraction plates are symmetrically arranged. In the middle of the inner wall of the cylinder shell, a sealing chuck is slidably connected. On the side of the sealing chuck away from the upper cover plate, a side spring is fixedly connected. At the bottom end of the inner wall of the material passing pipe, a side nozzle is slidably connected. After the feeding is completed, the lower template and the upper die cover connected above are controlled to rotate by 90 degrees through the external rotating shaft. At this time, the state inside the shaping cylinder is as Figure 4As shown, the outer surface of the upper mold cover squeezes the side nozzles on both sides against the inner wall of the cylinder shell, thereby blocking the side nozzles. At this time, the inside of the shaping cylinder is sealed. After the mold parts inside the lower template and the upper mold cover are cooled and formed, the lower template and the upper mold cover connected above are controlled to rotate 90 degrees through an external rotating shaft. The feeding device on the other side without added raw materials is used to ventilate through the material pipe. The pressure inside the cylinder shell increases, thereby pushing the upper cover plate upward. The upper cover plate pulls the upper mold cover and the lower template apart to obtain the finished mold. Because during the feeding and shaping process of this device, the material is in a relatively sealed state and does not come into contact with the outside world, there will be no problem of raw material leakage during the pouring of raw materials in the traditional casting industry. Therefore, the production environment is relatively clean and hygienic, the production process is relatively safe and reliable, and the working environment temperature of the staff will not be too high, which is conducive to the progress of production work.

[0010] Preferably, the lower surface of the lower template is rotatably connected to the upper surface of the fixed plate. The top of the control rotating rod is fixedly connected to the center of the lower surface of the lower template. The side surface of the lower template is rotatably connected to the outer surface of the sealing block. The outer surface of the upper mold cover is slidably connected to the outer surface of the sealing chuck. The outer surface of the upper mold cover is slidably connected to the outer surface of the side nozzle.

[0011] Preferably, the outer surface of the external rotating shaft is slidably connected to the inner wall of the friction transmission belt. The top of the friction rotating cylinder is rotatably connected to one side of the lower surface of the fixed plate. The upper part of the outer surface of the friction rotating cylinder is slidably connected to the inner wall of the friction transmission belt. The lower part of the inner wall of the external rotating shaft is fixedly connected to the outer surface of the output shaft of the control motor. When this device produces molds, it can carry out batch production through this device. Since the bottom ends of the two material pipes on both sides will be blocked by the outer surface of the upper mold cover during production, the irritating gas generated by the raw materials will not be emitted to the outside. After the model is cooled, the bottom ends of the material pipes can be opened for heat dissipation to prevent the premature mold opening phenomenon due to excessive pressure inside the shaping cylinder.

[0012] Preferably, the number of casting cylinders is five. The upper surface of the support wall is fixedly connected to one side of the lower surface of the fixed plate. The number of support walls is two. The number of control motors is two. The number of feeding devices is two.

[0013] Preferably, the magnetic attraction plate includes a rotating joint. An arc-shaped fan plate is rotatably connected to the outer surface of the rotating joint. A clamping strip is fixedly connected to one side of the outer surface of the arc-shaped fan plate close to the upper mold cover. A fixed magnetic strip is fixedly connected to one side of the outer surface of the arc-shaped fan plate far from the upper mold cover.

[0014] Preferably, the bottom end of the arc-shaped fan plate is rotatably connected to the outer surface of the rotating joint, the outer surface of the clamping strip is movably connected to the outer surface of the upper mold cover through a card slot, the upper mold cover is made of a metal material, and the lower template is made of a heat-resistant composite material. Due to the stabilizing effect of the magnetic attraction plate, when pouring the raw material, the upper mold cover and the lower template will not shake relative to each other due to the impact force. The side nozzle can accurately pour the raw material from the material inlet of the upper mold cover, preventing the problem that the raw material spills out of the upper mold cover due to inaccurate alignment.

[0015] Preferably, the feeding device includes a hollow bar. Pressing plates are symmetrically arranged on the front and rear sides of the inner wall of the hollow bar. Through holes are evenly formed in the lower part of the inner wall of the hollow bar. A threaded push rod is fixedly connected to one side of the outer surface of the pressing plate close to the inner wall of the hollow bar.

[0016] Preferably, one side of the lower surface of the hollow bar is fixedly connected to the outer surface of the support wall through a connecting plate. The lower surface of the hollow bar is fixedly connected to the outer surface of the material-passing pipe through a through hole. The top end of the material-passing pipe extends into the hollow bar through the through hole. Since the device controls the rotation of the threaded push rod, and then controls the amount of material injection and the amount of pressure, the quality of the product can be intuitively controlled, making the weight of the product more uniform, and the pressure progress can also be carried out slowly. Therefore, the mold opening force can be accurately controlled, preventing the problem that the mold opening force is too large and causing damage to the device.

[0017] Preferably, the number of the hollow bars is two. The outer surface of the pressing plate is slidably connected to the inner wall of the hollow bar, and the cross-sectional area of the pressing plate is the same as the cross-sectional area of the inner wall of the hollow bar. The outer surface of the threaded push rod is threadedly connected to one side of the inner wall of the hollow bar. The bottom end of the threaded push rod is rotatably connected to one side of the outer surface of the pressing plate. The top end of the threaded push rod extends to the outside of the hollow bar.

[0018] The beneficial effects of the present invention are as follows: 1. During the material injection process of the device, the material is in a relatively sealed state throughout the process and does not come into contact with air impurities in the outside world. Therefore, it is not easy for oxidation reaction to occur inside the unblocked material-passing pipe. And the two material-passing pipes on both sides are responsible for material transportation and ventilation respectively, and do not affect or interfere with each other. Therefore, the residual material inside the material-passing pipe is not easy to be oxidized into a solid, blocking the inside of the sealed pipe and affecting the material injection process.

[0019] 2. Since the material is in a relatively sealed state and does not come into contact with the outside world during the feeding and shaping process of the device, the problem of raw material leakage during the pouring of raw materials in the traditional foundry industry will not occur. Therefore, the production environment is relatively clean and hygienic, the production process is relatively safe and reliable, and the working environment temperature of the staff will not be too high, which is conducive to the progress of production work.

[0020] 3. When the device produces molds, batch production can be carried out through this device. Since the bottom ends of the material feeding pipes on both sides will be blocked by the outer surface of the upper mold cover during production, the irritating gas generated by the raw materials will not be emitted to the outside. After the model cools down, the bottom ends of the material feeding pipes can be opened for heat dissipation to prevent the premature mold opening phenomenon caused by excessive internal pressure in the shaping cylinder.

[0021] 4. Due to the stabilizing effect of the magnetic attraction plate, when pouring the raw materials, the upper mold cover and the lower template will not shake relatively due to the impact force. The side nozzles can accurately pour the raw materials from the material feeding port of the upper mold cover, preventing the problem of the raw materials spilling out of the upper mold cover due to inaccurate alignment.

[0022] 5. Since the device controls the rotation of the threaded push rod, and then controls the amount of material injection and the amount of pressure, the quality of the product can be intuitively controlled, making the weight of the product more uniform, and the pressure application progress can also be carried out slowly. Therefore, the mold opening force can be accurately controlled to prevent the problem of damage to the device caused by excessive mold opening force. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The bottom end of the arc-shaped fan plate 72 is rotatably connected to the outer surface of the rotating joint 71.

[0037] The feeding device 3 includes a hollow bar 31. Pressing push plates 33 are symmetrically arranged on the front and rear sides of the inner wall of the hollow bar 31. Through holes 32 are uniformly opened in the lower part of the inner wall of the hollow bar 31. One side of the outer surface of the pressing push plate 33 close to the inner wall of the hollow bar 31 is fixedly connected to a threaded push rod 34. Before using the device for casting, molten liquid raw materials are injected into one of the feeding devices 3, and then the two feeding devices 3 on both sides are sealed.

[0038] One side of the lower surface of the hollow bar 31 is fixedly connected to the outer surface of the support wall 2 through a connecting plate. The lower surface of the hollow bar 31 is fixedly connected to the outer surface of the material conveying pipe 43 through the through hole 32.

[0053] During the process of injecting materials, since the upper mold cover 52 is made of metal, when the outer surface of the upper mold cover 52 presses against the sealing chucks 64 on both sides, the fixed magnetic strips 73 on the magnetic attraction plate 7 will press against the outer surface of the upper mold cover 52 under the action of magnetic force, and then push the arc-shaped fan plate 72 to wrap around the outer surface of the upper mold cover 52. The clamping strip 74 is clamped with the upper mold cover 52 to stabilize the state of the upper mold cover 52 and the lower template 53, preventing the upper mold cover 52 and the lower template 53 from shaking due to the impact force when pouring raw materials.
