Description

Technical Field

[0001] The invention belongs to the technical field of casting, and in particular relates to energy-saving furnace roller automatic cooling mold opening casting equipment. Background Art

[0002] In industrial production, casting is an important processing method, especially in the processing of energy-saving furnace rollers, the casting device plays a key role. However, there are many problems with the existing casting equipment.

[0003] On the one hand, the overall structure of traditional casting equipment is usually in a static state during the casting process. When faced with casting materials with high viscosity, the material only relies on its own fluidity to fill the bottom of the cavity after being introduced into the cavity, which leads to low filling efficiency and uneven filling effect. This uneven filling will have an adverse effect on subsequent casting fillers, reducing product quality and production efficiency.

[0004] On the other hand, after casting, traditional casting devices often need to use external mold opening tools to open the mold, which is not only inefficient but also time-consuming and labor-intensive. This increases the complexity and labor costs of the operation, and also affects the use effect and production progress of the overall casting device.

[0005] To sum up, in order to solve the shortcomings of existing casting equipment in filling efficiency, filling effect and mold opening convenience, there is an urgent need for a new type of energy-saving furnace roller processing casting device to improve casting efficiency, improve filling effect and realize automatic mold opening, so as to meet the needs of industrial production for efficient, energy-saving and convenient casting equipment. Summary of the invention

[0006] The purpose of the present invention is to solve the problem that although the current casting equipment can complete the casting of materials, the overall casting structure is always in a static state during casting. During casting, some casting materials have a high viscosity. After the material is introduced into the cavity, the bottom of the cavity needs to be filled by the material's own fluidity. The overall filling efficiency is low and the filling effect is uneven, which affects the subsequent casting filler. At the same time, after the casting is completed, the subsequent mold opening requires the use of external mold opening tools, the mold opening efficiency is low, it is time-consuming and labor-intensive, and the overall casting device has a poor use effect. An energy-saving furnace roller automatic cooling mold opening casting equipment is proposed.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an energy-saving furnace roller automatic cooling open mold casting equipment, comprising a base, two touch pressure plates and a support assembly are fixedly installed on the top of the base, a casting molding mechanism is rotatably installed between the two support assemblies, the casting molding mechanism is used for casting molding of materials, and the two touch pressure plates and the support assemblies are symmetrically arranged about the longitudinal center axis of the base.

[0009] As a further description of the above technical solution: One end of the positioning pin is inserted into the positioning hole, a casting port is arranged on the top surface of the upper mold, and a casting cavity is arranged inside the lower mold.

[0010] Furthermore, by matching the casting molding mechanism and the supporting assembly, when casting is carried out, the casting material is first introduced into the casting molding mechanism through the casting port, and the casting material will first be filled on the lower mold. At this time, the supporting telescope is opened and the supporting telescope is extended. At this time, the driving motor is turned on, and the driving motor can drive the casting molding mechanism to rotate forward and reverse. At this time, the casting material filled on the lower mold can be evenly distributed on the bottom surface and the inner wall of the side of the lower mold. After the filling material is evenly distributed, the remaining material continues to be filled into the casting molding mechanism through the casting port until the filling is completed. Through this design, the casting molding mechanism is designed to be rockable. When the casting operation is carried out, the material can be effectively and stably filled at the bottom of the casting molding mechanism. The problem of filling the bottom of the cavity through the fluidity of the material itself, low overall filling efficiency, uneven filling effect, and affecting subsequent casting fillers is effectively solved, thereby improving the use effect of the overall equipment.

[0011] As a further description of the above technical solution: A mold opening accessory is arranged on the side plate arranged on the side wall of the lower mold, and the mold opening accessory is used for stable opening of the upper mold and the lower mold. The mold opening accessory includes a mounting shell, and a built-in spring device is fixedly installed inside the mounting shell.

[0012] As a further description of the above technical solution: A connecting column is fixedly installed at one end of the built-in spring device, one end of the connecting column is slidably connected to the inner wall of the mounting shell, an inner hole is arranged inside the connecting column, and a spring latch is arranged in the inner hole.

[0013] As a further description of the above technical solution: One end of the spring latch passes through and extends to the outside of the mounting shell, and the top end of the connecting column is fixedly mounted with an open mold top shell.

[0015] As a further description of the above technical solution: An expansion block is fixedly installed at one end of the side thrust spring, a flexible clamping column is fixedly installed on the top surface of the expansion block, one end of the flexible clamping column passes through and extends to the outside of the mold opening top shell, two inner holes are arranged inside the expansion block, mold opening springs are fixedly installed in both inner holes, and a mold opening top column is fixedly installed on the top of the mold opening spring.

[0016] As a further description of the above technical solution: The support assembly includes a support telescope, which is fixedly mounted on the top surface of the base, a drive motor is fixedly mounted on the side wall of the telescopic end of the support telescope, a rotating shaft is fixedly mounted on one end of the output shaft of the drive motor, and one end of the rotating shaft is fixedly connected to a mounting hole set on one side outer wall of the lower mold.

[0017] As a further description of the above technical solution: A cooling component is provided inside the base, and the cooling component is used for rapid cooling and forming of casting materials. The cooling component includes a liquid changing tank and a liquid storage tank, and the liquid changing tank and the liquid storage tank are both fixedly mounted on the inner wall of the bottom surface of the base, and the liquid changing tank and the liquid storage tank are connected by a liquid guide tube, and a coolant conduit is provided on the top surface of the liquid changing tank, and one end of the coolant conduit is fixedly connected to a water hole provided on the bottom surface of the lower mold, and a water pressure piston is provided inside the liquid storage tank, and the water pressure piston is slidably connected to the inner wall of the liquid storage tank, and a piston rod is fixedly mounted on the top surface of the water pressure piston, and the top end of the piston rod passes through and extends to the outside of the base, and a pressure plate is fixedly mounted on the top end of the piston rod, and a set spring is sleeved on the outside of the piston rod, and the pressure plate is located below the lower mold.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: First, by setting up the casting molding mechanism and the support assembly, the casting molding mechanism is designed to be swayable. During the casting operation, the casting material is first introduced into the casting molding mechanism, the support telescopic device and the drive motor are turned on, and the casting molding mechanism rotates forward and reversely. At this time, the casting material filled on the lower mold can be evenly distributed on the bottom surface and the inner wall of the side of the lower mold. After the filling material is evenly filled, the remaining material is continued to be filled, which effectively solves the problem of low filling efficiency and uneven effect caused by traditional casting relying on the material's own fluidity to fill the bottom of the cavity, and improves the overall equipment use effect and product quality.

[0019] Secondly, the matching cooling assembly and the touch plate, when the casting material is filled and needs to be cooled and formed, the support telescopic device is controlled to shorten, the height of the casting molding mechanism is lowered and deflected left and right, and its bottom end continuously touches the pressure plate, so that the coolant in the liquid storage tank is sent to the liquid exchange tank, and then introduced into the lower mold shell cavity through the coolant conduit, so as to quickly cool the material and form it. At the same time, the continuous shaking of the casting molding mechanism can also increase the cooling rate of the material, and the cooling does not require additional energy supply, which is highly energy-saving and improves the overall equipment efficiency.

[0020] Finally, the mold opening accessories are set. When the mold is opened after the material is cooled and formed, the height of the casting molding mechanism is lowered, the touch plate touches the spring latch to retract it, and the connecting column and the mold opening top shell are pushed up and popped out by the built-in spring device, giving the upper mold an upward impact force to achieve separation. At the same time, after the flexible clamping column is compressed and deformed into the mold opening top shell, the expansion block pops out under the action of the side push spring, and the mold opening top column quickly pushes up under the action of the mold opening spring, giving the upper mold side shell a secondary impact force, further improving the mold opening effect, realizing automatic mold opening, and no manual control is required, which greatly improves the use effect and convenience of the overall device.

[0034] The specific implementation method is as follows: during casting, the casting material is first introduced into the casting molding mechanism 4 through the casting port 41, and the casting material will first fill the lower mold 43.

At this time, the drive motor 31 is turned on, and the drive motor 31 can drive the casting molding mechanism 4 to rotate forward and reverse. At this time, the casting material filled on the lower mold 43 can be evenly distributed on the bottom surface and the side inner wall of the lower mold 43. After the filling material is evenly distributed, the remaining material continues to be filled into the casting molding mechanism 4 through the casting port 41 until the filling is completed.

[0035] Through this design, the casting molding mechanism 4 is designed to be rockable, so that the material can be effectively and quickly filled at the bottom of the casting molding mechanism 4 during the casting operation, effectively solving the problem of filling the bottom of the cavity through the fluidity of the material itself, low overall filling efficiency, uneven filling effect, and affecting subsequent casting fillings, thereby improving the use effect of the overall equipment.

[0036] A mold opening accessory 44 is arranged on the side plate arranged on the side wall of the lower mold 43, and the mold opening accessory 44 is used for stable opening of the upper mold 42 and the lower mold 43.

Two inner holes are provided inside the expansion block 4434, and mold opening springs 4432 are fixedly mounted in both inner holes, and a mold opening top column 4431 is fixedly mounted on the top of the mold opening spring 4432.

[0038] The specific implementation method is as follows: after the casting material is filled and the material needs to be cooled and formed, the support telescopic device 32 can be controlled to shorten, and the height of the casting molding mechanism 4 drops. The casting molding mechanism 4 continues to be controlled to deflect left and right. When the casting molding mechanism 4 deflects left and right, the bottom end of the casting molding mechanism 4 can produce continuous contact pressure on the pressure plate 53. At this time, the coolant in the liquid storage tank 56 can be continuously delivered to the liquid exchange tank 52, and finally introduced into the shell cavity of the lower mold 43 through the coolant conduit 51, so as to quickly cool the material in the lower mold 43 so that the material can be quickly formed. In this way, the real-time exchange of the coolant can be realized, and the cooling effect can be maintained continuously. At the same time, the continuous shaking of the casting molding mechanism 4 will also increase the cooling rate of the material in the casting molding mechanism 4, thereby improving the use effect and efficiency of the overall equipment. In addition, cooling does not require additional energy supply, and is highly energy-saving.

[0039] A cooling assembly 5 is provided inside the base 1, and the cooling assembly 5 is used for rapid cooling and molding of casting materials. The cooling assembly 5 includes a liquid changing tank 52 and a liquid storage tank 56, and the liquid changing tank 52 and the liquid storage tank 56 are both fixedly mounted on the inner wall of the bottom surface of the base 1, and the liquid changing tank 52 and the liquid storage tank 56 are connected by a liquid guide tube, and a coolant conduit 51 is provided on the top surface of the liquid changing tank 52, and one end of the coolant conduit 51 is fixedly connected to a water hole provided on the bottom surface of the lower mold 43, and a water pressure piston is provided inside the liquid storage tank 56, and the water pressure piston is slidably connected to the inner wall of the liquid storage tank 56, and a piston rod 54 is fixedly mounted on the top surface of the water pressure piston, and the top end of the piston rod 54 passes through and extends to the outside of the base 1, and a pressure plate 53 is fixedly mounted on the top end of the piston rod 54, and a sleeve spring 55 is sleeved on the outside of the piston rod 54, and the pressure plate 53 is located below the lower mold 43.

[0040] The specific implementation method is as follows: after the material is cooled and formed, when the mold is opened, the height of the casting molding mechanism 4 is further lowered, and the touch plate 2 can generate contact pressure on the spring latch 442 of the mold opening accessory 44, and the spring latch 442 under the contact pressure can be retracted to the inside of the mounting shell 446. At this time, the connecting column 444 and the mold opening top shell 441 can be pushed up and popped out under the action of the built-in spring device 445. At this time, the mold opening top shell 441 contacts the side shell of the upper mold 42 and gives the upper mold 42 an upward impact force, so as to achieve The upper mold 42 is separated from the lower mold 43. At the same time, when the mold opening top shell 441 contacts the side shell of the upper mold 42, the flexible clamping column 4433 is compressed and deformed and retracted into the mold opening top shell 441. At this time, the expansion block 4434 can pop out under the action of the side push spring 4435. When the expansion block 4434 is separated from the mold top shell 441, the mold opening top column 4431 can also be quickly pushed up under the action of the mold opening spring 4432, giving the side shell of the upper mold 42 a secondary impact force, thereby further improving the mold opening effect.

[0041] Through this design, the upper mold 42 and the lower mold 43 can be automatically opened after the furnace roller casting, without the need for manual control, which greatly improves the use effect and convenience of the overall device.

[0042] Working principle: During casting, the casting material is first introduced into the casting molding mechanism 4 through the casting port 41. The casting material will first fill the lower mold 43. At this time, the support retractor 32 is turned on and the support retractor 32 is extended. At this time, the drive motor 31 is turned on and the drive motor 31 can drive the casting molding mechanism 4 to rotate forward and reverse. At this time, the casting material filled on the lower mold 43 can be evenly distributed on the bottom surface and the inner wall of the side of the lower mold 43. After the filling material is evenly distributed, the remaining material is continued to be filled into the casting molding mechanism 4 through the casting port 41 until the filling is completed; After the material is filled, when the material needs to be cooled and formed, the support telescopic device 32 can be controlled to shorten, and the height of the casting molding mechanism 4 can be lowered. The casting molding mechanism 4 can continue to be controlled to deflect left and right. When the casting molding mechanism 4 deflects left and right, the bottom end of the casting molding mechanism 4 can produce continuous contact pressure on the pressure plate 53. At this time, the coolant in the liquid storage tank 56 can be continuously sent to the liquid exchange tank 52, and finally introduced into the shell cavity of the lower mold 43 through the coolant conduit 51, so as to quickly cool the material in the lower mold 43, so that the material can be quickly formed. In this reciprocating manner, the real-time exchange of the coolant can also be realized. The continuous shaking of the casting molding mechanism 4 will also increase the cooling rate of the material in the casting molding mechanism 4, thereby improving the use effect and efficiency of the overall equipment. After the material is cooled and formed, when the mold is opened, the height of the casting molding mechanism 4 is further lowered. At this time, the touch plate 2 can produce contact pressure on the spring latch 442 of the mold opening accessory 44. The spring latch 442 under the contact pressure can be retracted to the inside of the installation shell 446. At this time, the connecting column 444 and the mold opening top shell 441 can be pushed up and popped out under the action of the built-in spring device 445. At this time, the mold opening top shell 441 and the upper mold 4 2 and give an upward impact force to the upper mold 42 to achieve the separation of the upper mold 42 and the lower mold 43. At the same time, when the mold opening top shell 441 contacts the side shell of the upper mold 42, the flexible clamping column 4433 is compressed and deformed and retracted into the mold opening top shell 441. At this time, the expansion block 4434 can be ejected under the action of the side push spring 4435. When the expansion block 4434 is separated from the mold top shell 441, the mold opening top column 4431 can also be quickly pushed up under the action of the mold opening spring 4432, giving a secondary impact force to the side shell of the upper mold 42, thereby further improving the mold opening effect.
