DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figures 1 to 8As shown, a fire protection pipe fitting casting device described in an embodiment of the present invention includes a workbench 1 and a mold assembly. A through slot 2 is opened on the top of the workbench 1. The mold assembly includes a fixed mold 3, a core shaft 4, a movable mold 5 and a driving plate 6. The fixed mold 3 is fixedly installed on the inner wall of the through slot 2, the core shaft 4 is fixedly installed on the inner wall of the fixed mold 3, the movable mold 5 is slidably installed on the inner wall of the fixed mold 3, the end of the core shaft 4 away from the fixed mold 3 is slidably connected to the movable mold 5, the driving plate 6 is fixedly installed on the outer wall of the movable mold 5, and a separation assembly is arranged on one side of the movable mold 5. The mold assembly separates the movable mold 5 from the fixed mold 3 through the separation assembly. When performing casting work, the movable mold 5 and the fixed mold 3 are kept in close contact to form a complete mold, and metal in a molten state is injected into the interior of the fixed mold 3. The metal liquid is distributed in the shape of a pipe fitting through the cooperation of the movable mold 5, the fixed mold 3 and the core shaft 4. The pipe fitting can be formed after the metal liquid is cooled and fixed. When it is necessary to unload the material, the separation component causes the driving plate 6 to move away from the fixed mold 3. When the driving plate 6 moves, it will drive the movable mold 5 to move, thereby separating the movable mold 5 from the fixed mold 3. When the movable mold 5 and the fixed mold 3 are separated, the bottom of the fixed mold 3 is in an open state. At this time, the formed pipe fitting can be separated from the bottom of the fixed mold 3, thereby achieving the effect of facilitating demoulding.

[0024] like Figures 1 to 5 As shown, the separation component includes a driving motor 7, which is fixedly installed at the bottom of the workbench 1. A traveling screw 8 is fixedly installed at the output end of the driving motor 7. The outer wall of the traveling screw 8 is rotatably connected to the inner wall of the workbench 1. The outer wall of the traveling screw 8 is threadedly connected to a lifting block 9. The outer wall of the lifting block 9 is symmetrically fixedly installed with a connecting outer frame 10. A lifting shaft 11 is fixedly installed between the inner walls of the two connecting outer frames 10. The lifting shaft 11 is located above the end of the driving plate 6 away from the moving mold 5. A reset assembly is arranged on the inner side of the through slot 2. The movable mold 5 is reset by the reset component provided; when the separation component is working, the driving motor 7 drives the traveling screw 8 to rotate. When the traveling screw 8 rotates, it cooperates with the lifting block 9 to make the lifting block 9 descend. When the lifting block 9 descends, it drives the lifting shaft 11 to descend through the connecting outer frame 10. When the lifting shaft 11 descends, it presses down the driving plate 6. When the lifting shaft 11 presses down the inclined surface of the driving plate 6, the driving plate 6 will move, thereby achieving the effect of driving the movable mold 5 to separate from the fixed mold 3.

[0025] like Figure 2 and Figures 4 to 6As shown, the reset assembly includes a linear telescopic rod 12 and a linear elastic member 13, one end of the linear telescopic rod 12 and the linear elastic member 13 are fixedly connected to the inner wall of the through groove 2, and the other end of the linear telescopic rod 12 and the linear elastic member 13 are fixedly connected to the outer wall of the movable mold 5, and the linear elastic member 13 is sleeved on the outer side of the linear telescopic rod 12; when the driving plate 6 drives the movable mold 5 to separate from the fixed mold 3, the linear elastic member 13 will be squeezed by the movable mold 5, and the linear elastic member 13 is in a compressed state. When the demoulding work is completed, the lifting shaft 11 will rise again. When the lifting shaft 11 rises, the movable mold 5 will be pushed to move under the action of the reverse elastic force of the linear elastic member 13, so that the movable mold 5 is fitted with the fixed mold 3 again, thereby achieving the effect of automatic reset.

[0026] like Figures 1 to 3 and Fig. 9 As shown, the outer wall of the lifting shaft 11 is symmetrically fixed with vertical plates 14, and a horizontal plate 15 is fixedly installed between the ends of the two vertical plates 14 away from the lifting shaft 11. A pressing block 16 is fixedly installed at the bottom of the end of the horizontal plate 15 away from the vertical plate 14, and the pressing block 16 is located above the movable mold 5; when the lifting shaft 11 moves to the end position of the inclined surface of the driving plate 6, the movable mold 5 is separated from the fixed mold 3, and the condition for the pipe fitting to be separated from the fixed mold 3 has been met. In this process, the pressing block 16 will follow the lifting shaft 11 to fall to a position that fits the top of the pipe fitting under the action of the horizontal plate 15 and the vertical plate 14, and then the lifting shaft 11 will continue to fall. When continuing to fall, the lifting shaft 11 will pass through a vertical section of the driving plate 6, and the movable mold 5 will no longer move, while the pressing block 16 will continue to fall. When the pressing block 16 continues to fall, it will squeeze the already formed pipe fitting, so that the pipe fitting is separated from the inside of the fixed mold 3, thereby achieving the effect of automatic demolding.

[0027] like Figures 9 to 11As shown, the outer wall of the fixed mold 3 is symmetrically provided with a knocking assembly, which includes a positioning seat 17 fixedly installed on the outer wall of the fixed mold 3, a rotating shaft 18 is rotatably installed on the inner wall of the positioning seat 17, a rotating plate 19 is rotatably installed on the outer wall of the rotating shaft 18, a mounting block 20 is fixedly installed on one end of the rotating plate 19, a rubber hammer 21 is fixedly installed on the outer wall of the mounting block 20, and the outer walls of the two rubber hammers 21 are both fitted with the outer wall of the fixed mold 3, an arc-shaped telescopic rod 22 and an arc-shaped elastic member 23 are fixedly installed between the positioning seat 17 and the outer wall of the rotating plate 19, and the arc-shaped elastic member 23 is sleeved on the outer side of the arc-shaped telescopic rod 22, and a toggle assembly is symmetrically provided on one side of the fixed mold 3, and the knocking assembly causes the rubber hammer 21 to knock on the fixed mold 3 through the toggle assembly; in the process of casting, the toggle assembly will reciprocate through the knocking assembly, and whenever the toggle assembly passes through the knocking assembly When the assembly is moved, the rotating plate 19 will be squeezed away from one end of the mounting block 20 under the action of the toggle assembly, and the rotating plate 19 will rotate around the rotating shaft 18. When the rotating plate 19 rotates, the arc-shaped elastic member 23 will be squeezed by the rotating plate 19 and contracted, and the rubber hammer 21 will separate from the fixed mold 3. When the toggle assembly passes over the rotating plate 19, the rotating plate 19 will rotate in the opposite direction under the action of the arc-shaped elastic member 23, so that the rubber hammer 21 will hit the fixed mold 3. When the toggle assembly reciprocates, the rubber hammer 21 will reciprocate and hit the fixed mold 3 to vibrate the fixed mold 3. When the molten metal is added, the density of the molten metal can be further improved by vibration, and the strength and durability of the pipe fittings can be enhanced. After the pipe fittings are formed, the adhesion between the pipe fittings and the mold can be reduced by vibration, thereby preventing the pipe fittings from being strained during demolding, thereby improving the demolding effect of the device.

[0028] like Figures 9 to 11 As shown, the toggle assembly includes a connecting frame 24 fixedly mounted on the outer wall of the vertical plate 14, and a connecting shaft 25 is symmetrically fixedly mounted on one end of the connecting frame 24 away from the vertical plate 14, and an arc-shaped extrusion shaft 26 is fixedly mounted between one end of the two connecting shafts 25, and the two arc-shaped extrusion shafts 26 are respectively located below one end of the two rotating plates 19 away from the mounting block 20; when the toggle assembly is working, the vertical plate 14 is lifted and lowered under the action of the driving motor 7, and the vertical plate 14 drives the arc-shaped extrusion shaft 26 through the connecting frame 24 and the connecting shaft 25. When the arc extrusion shaft 26 is lifted and lowered, the rotating plate 19 will be reciprocatedly squeezed to make it rotate. As the rotating plate 19 rotates, it will gradually move away from the arc extrusion shaft 26. When the rotating plate 19 is separated from the arc extrusion shaft 26, the rotating plate 19 will reverse under the action of the arc elastic member 23, thereby achieving the knocking of the fixed mold 3. The arc extrusion shaft 26 will reciprocate and rise first and then fall. During this process, the lifting shaft 11 will not contact the driving plate 6, so that the movable mold 5 and the fixed mold 3 remain in a fitted state.

[0029] like Figures 9 to 12As shown, the outer wall of the fixed mold 3 is symmetrically fixed with a fixed block 27, and the outer wall of the movable mold 5 is symmetrically fixed with a positioning block 28. The outer walls of the two positioning blocks 28 are respectively slidably connected with the inner walls of the two fixed blocks 27. The bottoms of the two connecting frames 24 are fixedly installed with a receiving plate 29. The top of the receiving plate 29 away from the connecting frame 24 is fixedly installed with a pin 30. One end of the two pins 30 is respectively inserted into the inner wall of the fixed block 27. After each demoulding work is completed, the movable mold 5 is reset as the lifting shaft 11 rises. When the movable mold 5 is fitted with the fixed mold 3, the positioning block 28 will enter the inner side of the fixed block 27. At this time, under the action of the connecting frame 24, the receiving plate 29 drives the pin 3 0 is moved up and inserted into the fixed block 27. Then, with the continuous rise of the lifting shaft 11, the pin 30 will pass through the positioning block 28, thereby locking the movable mold 5 to ensure the sealing effect between the movable mold 5 and the fixed mold 3. The connecting frame 24 will not enable the rubber hammer 21 to perform the knocking work until it continues to rise. That is, when the knocking work is performed, the movable mold 5 is in a locked state to avoid liquid leakage during the knocking process. When the demoulding work is performed, before the lifting shaft 11 squeezes the driving plate 6, the pin 30 will slide out from the inner side of the positioning block 28, so that the movable mold 5 is released from the locked state when the demoulding begins, thereby achieving the effect of automatically locking and unlocking the movable mold 5. The device is particularly convenient to use.

[0030] like Figure 1 As shown, a containing box 31 is fixedly installed on the top of the workbench 1, and a conveying pipe 32 is connected between the containing box 31 and the fixed mold 3; the containing box 31 is used to carry the molten metal for casting. When the casting work is carried out, the containing box 31 will convey the molten metal to the inside of the mold through the conveying pipe 32 under the action of negative pressure, so as to achieve the effect of raw material transportation.

[0031] like Figure 1 to Figure 2 As shown, a motor seat 33 is fixedly installed at the bottom of the workbench 1, and the inner wall of the motor seat 33 is fixedly connected to the outer wall of the drive motor 7. Limiting columns 34 are symmetrically fixedly installed on the top of the workbench 1, and the outer walls of the two limiting columns 34 are slidingly connected to the inner walls of the two connecting outer frames 10 respectively; the driving motor 7 is fixed by the motor seat 33 so that the driving motor 7 can provide power for the operation of the device, and the connecting outer frame 10 is limited by the limiting columns 34 to ensure the stability of the connecting outer frame 10 during lifting.

[0032] like Figure 1 to Figure 2 and Figure 5As shown, a slider 35 is symmetrically fixedly installed on the outer wall of the movable mold 5 near the bottom, and a slide column 36 is symmetrically fixedly installed on the bottom of the workbench 1. The end of the slide column 36 away from the workbench 1 is fixedly connected to the motor base 33, and the inner walls of the two sliders 35 are slidably connected to the outer walls of the two slide columns 36 respectively; through the cooperation of the slider 35 and the slide column 36, while ensuring that the movable mold 5 has the conditions for moving, the stability of the movable mold 5 during movement is increased, and the movable mold 5 is prevented from being offset during movement.

[0033] Working principle: During casting, the receiving box 31 will transport the molten metal to the inside of the mold through the delivery pipe 32 under the action of negative pressure. The movable mold 5 and the fixed mold 3 are kept in close contact to form a complete mold. The molten metal is distributed in the shape of a pipe through the cooperation of the movable mold 5, the fixed mold 3 and the mandrel 4. When the molten metal is cooled and fixed, the pipe can be formed. When it is necessary to unload the material, the separation component moves the driving plate 6 away from the fixed mold 3. When the driving plate 6 moves, it will drive the movable mold 5 to move, so that the movable mold 5 is separated from the fixed mold 3. When the movable mold 5 is moved, the movable mold 5 is separated from the fixed mold 3. After the mold 5 and the fixed mold 3 are separated, the bottom of the fixed mold 3 is in an open state. At this time, the formed pipe fitting can be separated from the bottom of the fixed mold 3, so as to achieve the effect of facilitating demoulding. When the separation component is working, the driving motor 7 drives the traveling screw 8 to rotate. When the traveling screw 8 rotates, it cooperates with the lifting block 9 to make the lifting block 9 descend. When the lifting block 9 descends, it drives the lifting shaft 11 to descend through the connection outer frame 10. When the lifting shaft 11 descends, it presses down the driving plate 6. When the lifting shaft 11 presses down the inclined surface of the driving plate 6, the driving plate 6 will move. The movable mold 5 is moved to achieve the effect of driving the movable mold 5 to separate from the fixed mold 3. When the driving plate 6 drives the movable mold 5 to separate from the fixed mold 3, the linear elastic member 13 will be squeezed by the movable mold 5. At this time, the linear elastic member 13 is in a compressed state. When the demoulding work is completed, the lifting shaft 11 will rise again. When the lifting shaft 11 rises, the movable mold 5 will push the movable mold 5 to move under the action of the reverse elastic force of the linear elastic member 13, so that the movable mold 5 is fitted with the fixed mold 3 again, thereby achieving the effect of automatic reset. When the lifting shaft 11 moves to the end point of the inclined surface of the driving plate 6 Position, the movable mold 5 and the fixed mold 3 are separated. At this time, the condition for the pipe fitting to be separated from the fixed mold 3 has been met. In this process, the pressing block 16 will follow the lifting shaft 11 to fall to a position that fits the top of the pipe fitting under the action of the horizontal plate 15 and the vertical plate 14, and then the lifting shaft 11 will continue to fall. When continuing to fall, the lifting shaft 11 will pass through a vertical section of the driving plate 6. The movable mold 5 will not continue to move, and the pressing block 16 will continue to fall. When the pressing block 16 continues to fall, it will squeeze the already formed pipe fitting, so that the pipe fitting will be separated from the inside of the fixed mold 3, thereby achieving the effect of automatic demolding.

[0034] During the casting process, the toggle assembly will reciprocate through the knocking assembly. Whenever the toggle assembly passes through the knocking assembly, the toggle assembly will squeeze the end of the rotating plate 19 away from the mounting block 20, and the rotating plate 19 will rotate around the rotating shaft 18. When the rotating plate 19 rotates, the arc-shaped elastic member 23 will be squeezed by the rotating plate 19 and shrink, and the rubber hammer head 21 will separate from the fixed mold 3. When the toggle assembly passes over the rotating plate 19, the rotating plate 19 will rotate in the opposite direction under the action of the arc-shaped elastic member 23, so that the rubber hammer head 21 knocks the fixed mold 3. When the toggle assembly reciprocates, the rubber hammer head 21 will reciprocate and knock the fixed mold 3 to vibrate the fixed mold 3. When the molten metal is added, the density of the molten metal can be further improved by vibration, and the strength and durability of the pipe fittings can be enhanced. After the pipe fittings are formed, Vibration can reduce the adhesion between the pipe fitting and the mold, thereby preventing the pipe fitting from being strained during demoulding and improving the demoulding effect of the device. When the toggle assembly is working, the vertical plate 14 is lifted and lowered under the action of the drive motor 7, and the vertical plate 14 will drive the arc extrusion shaft 26 to lift and lower through the connecting frame 24 and the connecting shaft 25. When the arc extrusion shaft 26 is lifted and lowered, the rotating plate 19 will be reciprocated and squeezed to rotate. As the rotating plate 19 rotates, it will gradually move away from the arc extrusion shaft 26. When the rotating plate 19 is separated from the arc extrusion shaft 26, the rotating plate 19 will reverse under the action of the arc elastic member 23, thereby achieving the knocking of the fixed mold 3. The arc extrusion shaft 26 will reciprocate and rise and then fall. In this process, the lifting shaft 11 will not contact the driving plate 6, so that the movable mold 5 and the fixed mold 3 remain in a fitted state.

[0035] When the demoulding work is completed each time, the movable mold 5 is reset as the lifting shaft 11 rises. When the movable mold 5 is fitted with the fixed mold 3, the positioning block 28 will enter the inner side of the fixed block 27. At this time, under the action of the connecting frame 24, the receiving plate 29 drives the pin 30 to move up and insert into the fixed block 27. Then, under the continuous rise of the lifting shaft 11, the pin 30 will pass through the positioning block 28, thereby locking the movable mold 5 to ensure the sealing effect between the movable mold 5 and the fixed mold 3. The connecting frame 24 will not enable the rubber hammer 21 to perform the knocking work until it continues to rise. That is, when the knocking work is performed, the movable mold 5 is in a locked state to avoid leakage during the knocking process. When the demoulding work is performed, before the lifting shaft 11 squeezes the driving plate 6, the pin 30 will slide out from the inner side of the positioning block 28, so that the movable mold 5 is released from the locked state when the demoulding starts, thereby achieving the effect of automatically locking and unlocking the movable mold 5. The device is particularly convenient to use.
