Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-5 The utility model provides a technical solution: a feeding mechanism for casting automobile parts, comprising a base 1, a lower mold 2 is installed on the upper surface of the base 1, an upper mold 3 is installed on the upper surface of the base 1, the upper mold 3 is located above the lower mold 2, a connecting seat 4 is installed on the upper surface of the upper mold 3, a feeding pipe 5 is connected to the side wall of the lower mold 2, a preheating structure 6 is provided in the lower mold 2, and a guide structure 7 is provided on the side wall of the lower mold 2.

[0032] The specific arrangement and function of the preheating structure 6 and the guide structure 7 will be described in detail below.

[0033] like Figure 2 and Figure 3As shown, the preheating structure 6 includes a preheating chamber 601, which is opened on the side wall of the lower mold 2, and the inner wall of the preheating chamber 601 is slidably connected to the electric heating plate 602, and the surface of the electric heating plate 602 is fixedly connected to the transmission belt 603, and the transmission belt 603 passes through the lower mold 2 and is fixedly connected to the upper mold 3.

The arc surface of the winding roller 606 is fixedly connected with a plurality of limit plates 609. The cross section of the limit plates 609 is "J"-shaped. The limit plates 609 can prevent the traction rope 607 from falling off the arc surface of the winding roller 606, thereby ensuring that the winding roller 606 can normally reel in the traction rope 607. The side wall of the lower mold 2 is fixedly connected with a heat preservation frame 610. The heat preservation frame 610 is connected to the preheating chamber 601. The size of the heat preservation frame 610 is adapted to the size of the electric heating plate 602. The traction rope 607 passes through the heat preservation frame 610. After the electric heating plate 602 slides into the inner wall of the heat preservation frame 610, the heat preservation frame 610 will insulate the electric heating plate 602.

[0034] like Figure 2 and Figure 4 as well as Figure 5As shown, the guide structure 7 includes a support plate 71, the support plate 71 is fixedly connected to the lower mold 2, the surface of the support plate 71 is rotatably connected to two guide cylinders 72, the guide cylinders 72 are slidably connected to the transmission belt 603, the surface of the support plate 71 is slidably sleeved with a rectangular tube 73, the surface of the rectangular tube 73 is fixedly connected to a sliding frame 74, the surface of the sliding frame 74 is rotatably connected to an adjusting cylinder 75, the adjusting cylinder 75 is slidably connected to the transmission belt 603, when the transmission belt 603 is loose, the bolt 76 is rotated, the bolt 76 will be disengaged from the support plate 71 by means of thread movement, and then the rectangular tube 73 will slide along the surface of the support plate 71, and the sliding frame 74 will slide with the help of the rectangular tube 73 The adjusting cylinder 75 is driven to slide, and the sliding of the adjusting cylinder 75 will squeeze the transmission belt 603, so that the transmission belt 603 is in a taut state again, ensuring that the transmission belt 603 can pull the electric heating plate 602 normally, and then the bolt 76 is rotated in the opposite direction to make the bolt 76 rest against the surface of the support plate 71 again, and the bolt 76 reaches the position of the limiting rectangular tube 73, thereby limiting the position of the adjusting roller, and the side wall of the lower mold 2 is fixedly connected to the limiting tube 77, and the transmission belt 603 passes through the limiting tube 77. When the transmission belt 603 passes through the limiting tube 77, the limiting tube 77 can limit the sliding direction of the transmission belt 603 to prevent the transmission belt 603 from being out of contact with the guide cylinder 72

[0035] Working principle: when it is necessary to produce the motor housing of an electric vehicle, firstly connect the output end of the external driving device (not shown in the figure) with the connecting seat 4 for installation, so that the external driving device (not shown in the figure) can control the upper mold 3 to move in the vertical direction, and then connect the feeding pipe 5 with the silo (not shown in the figure) for installation. During the casting process, start the electric heating plate 602, which will convert electrical energy into thermal energy. When the upper mold 3 moves upward and is demolded from the lower mold 2, the upper mold 3 will pull the transmission belt 603, and the transmission belt 603 will pass through the lower mold 2 to drive the electric heating plate 602 to slide from the inner wall of the insulation frame 610 into the inner wall of the preheating chamber 601. At this time, the electric heating plate 602 will heat the lower mold 2, and the sliding of the electric heating plate 602 will pull the traction rope 607, which will unfold from the arc surface of the winding roller 606. At this time, the winding roller 606 will drive the rotating rod 605 to rotate, and the winding roller 606 will twist the torsion spring 608, so that the torsion spring 608 is in a twisted state. After the lower mold 2 is heated to a suitable temperature, the upper mold 3 is controlled to move down and the electric heating plate 602 is closed. At this time, the transmission belt 603 begins to relax, and the torsion spring 608 will use its own torque to make the winding roller 606 rotate in the opposite direction to reel in the traction rope 607. At this time, the limit plate 609 can prevent the traction rope 607 from falling off the arc surface of the winding roller 606, ensuring that the winding roller 606 can normally reel in the traction rope 607. The traction rope 607 will pull the electric heating plate 602 into the inner wall of the insulation frame 610, and the insulation frame 610 will keep the electric heating plate 602 warm. After the upper mold 3 and the lower mold 2 are molded together, the raw material is injected into the lower mold 2 through the feeding pipe 5. When the raw material is cooled, the motor housing can be made.

[0036] During the movement of the transmission belt 603, the guide cylinder 72 will adjust the movement angle of the transmission belt 603 so that the transmission belt 603 passes through the lower mold 2 horizontally, thereby preventing the transmission belt 603 from being excessively worn by the lower mold 2, and extending the service life of the transmission belt 603, thereby ensuring that the transmission belt 603 can normally pull the electric heating plate 602 to move. When the transmission belt 603 is loose, the bolt 76 is turned, and the bolt 76 is disengaged from the support plate 71 by means of thread movement, and then the rectangular tube 73 slides along the surface of the support plate 71, and the sliding frame 74 slides with the help of the rectangular tube 73. The adjusting cylinder 75 will be driven to slide, and the sliding of the adjusting cylinder 75 will squeeze the transmission belt 603, so that the transmission belt 603 is in a taut state again, ensuring that the transmission belt 603 can pull the electric heating plate 602 normally, and then the bolt 76 is rotated in the opposite direction to make the bolt 76 rest against the surface of the support plate 71 again, and the bolt 76 reaches the position of the limiting rectangular tube 73, thereby limiting the position of the adjusting roller. When the transmission belt 603 passes through the limiting tube 77, the limiting tube 77 can limit the sliding direction of the transmission belt 603 to prevent the transmission belt 603 from being out of contact with the guide cylinder 72.
