[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0029] In order to save manpower and improve efficiency, as an embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the utility model describes a reducer housing mold that is easy to demold, comprising a base 1, a connecting cover 2 and a connecting pipe 26. A fixed mold 11 is provided on the upper outer wall of the base 1, a movable mold 12 is provided on the upper outer wall of the fixed mold 11, a connecting cover 2 is provided on one side of the outer wall of the fixed mold 11, and exhaust pipes 24 equidistantly distributed in parallel are installed on one side of the outer wall of the connecting cover 2. A ventilation groove 23 is provided inside the connecting cover 2, a connecting pipe 27 is installed on one side of the outer wall of the lower end of the connecting cover 2, and a fixed block 14 is installed on one side of the outer wall of the movable mold 12.
[0030] When in use, the external push rod mechanism drives the movable mold 12 to move vertically, thereby realizing the separation and closing of the fixed mold 11 and the movable mold 12, so that the metal solution is cooled and formed through the mold core between the fixed mold 11 and the movable mold 12.
[0031] For casting workpieces, for example, Figure 2 As shown, mold cores are provided on the outer walls of the fixed mold 11 and the movable mold 12 on opposite sides, and a feed port 13 is provided on one side of the outer wall of the upper end of the movable mold 12.
[0032] During use, after the fixed mold 11 and the movable mold 12 are closed, the molten metal can be injected into the mold core through the external injection mechanism and the feed port 13. The mold core can limit the molding shape of the workpiece, and the molten metal can be cooled and formed inside the mold core.
[0033] In order to keep the connection cover 2 in the use position, for example, Figure 1 As shown, support blocks 21 are installed on the outer walls of both sides of the connecting cover 2. The support blocks 21 are located outside the fixed mold 11. Bolts 22 are provided inside the support blocks 21, and the support blocks 21 are connected to the fixed mold 11 through the bolts 22.
[0034] During use, the support block 21 can be fixed by the bolts 22 , thereby keeping the connection cover 2 in a stable position outside the fixed mold 11 and ensuring the stable position of the nozzle 25 .
[0035] For airflow ejection, for example, Figure 3 As shown, the exhaust pipe 24 is designed in a curved shape. The exhaust pipe 24 is connected to the interior of the ventilation groove 23. A nozzle 25 is installed on the outer wall of one end of the exhaust pipe 24.
[0036] When in use, the gas inside the ventilation groove 23 can be ejected through the exhaust pipe 24 and the nozzle 25, so that the airflow ejected by the nozzle 25 flows to the workpiece, which can cool the workpiece inside the mold core, and the ejection direction and range of the airflow can be controlled by the selected model of the nozzle 25.
[0037] For air intake, for example, Figure 1As shown, an air intake pipe 28 is plugged and installed on one side of the outer wall of the lower end of the connecting pipe 27, and the air intake pipe 28 is connected to the interior of the ventilation groove 23 through the connecting pipe 27.
[0038] When in use, the air inlet pipe 28 is connected to an external air pump, which can pressurize the gas and then transport it to the inside of the connecting pipe 27 until the air flow flows into the inside of the ventilation groove 23.
[0039] In order to accommodate the piston body 16, for example, Figure 4 As shown, a connecting pipe 26 is plugged and installed on one side of the upper end of the outer wall of the connecting cover 2, and the connecting pipe 26 is connected to the interior of the ventilation groove 23.
[0040] When in use, the connecting pipe 26 can accommodate the piston body 16 to prevent the piston body 16 from remaining inside the ventilation groove 23 , ensuring that the piston body 16 is controlled to block the connecting pipe 27 .
[0041] In order to adjust the use position of the piston body 16, for example, Figure 1 As shown, a connecting rod 15 is installed on one side of the outer wall of the lower end of the fixing block 14 , and a piston body 16 is installed on the outer wall of the lower end of the connecting rod 15 . The piston body 16 is located inside the connecting pipe 26 .
[0042] During use, the movable mold 12 can drive the piston body 16 to move through the fixed block 14 and the connecting rod 15, can adjust the use position of the piston body 16, and the piston body 16 can be driven to move into the connecting pipe 27 to block the connecting pipe 27.
[0043] When the utility model is in use, the external push rod mechanism drives the movable mold 12 to move vertically, thereby realizing the separation and closing of the fixed mold 11 and the movable mold 12. When the fixed mold 11 and the movable mold 12 are closed, the external injection mechanism injects the metal solution into the mold core through the feed port 13, and the metal solution can be cooled and formed inside the mold core;
[0044] The push rod body drives the movable mold 12 to split the mold, and the ejector rod inside the fixed mold 11 can eject the workpiece cooled and formed inside the mold cavity, so that the workpiece is separated from the mold cavity.
[0045] According to the above-mentioned movement steps of the movable mold 12, the movable mold 12 can drive the fixed block 14, the connecting rod 15 and the piston body 16 to move until the piston body 16 enters the connecting pipe 26, so that the piston body 16 is freed from the blockage of the connecting pipe 27. The external air pump pressurizes the air and delivers it to the inside of the air inlet pipe 28, so that the air flow enters the inside of the ventilation groove 23 through the connecting pipe 27, and the gas inside the ventilation groove 23 is ejected through the exhaust pipe 24 and the nozzle 25. The nozzle 25 can control the ejection angle and range of the gas, so that the air flow can flow at the upper and lower ends of the workpiece after ejection, and the workpiece can continue to be cooled after the mold is opened.
[0046] After the fixed mold 11 and the movable mold 12 are closed, the connecting rod 15 pushes the piston body 16 into the connecting pipe 27 to block the connecting pipe 27, ensuring that the gas enters the connecting groove through the connecting pipe 27 in a controlled manner, ensuring controlled use of the airflow.
