DETAILED DESCRIPTION

[0023] Embodiment 1

[0025] A power assembly for driving the transmission belt 2 to rotate is installed on the frame 1 , and a plurality of through holes 201 are evenly formed on the transmission belt 2 .

[0026] The plurality of casting molds 14 correspond to the plurality of perforations 201 one by one, and the plurality of casting molds 14 are distributed on the outside of the transmission belt 2; a mounting rod 15 is provided on one side of the plurality of casting molds 14, and the mounting rod 15 is connected to the transmission belt 2, and a first elastic reset component is connected between the casting mold 14 and the mounting rod 15, and the first elastic reset component includes a sliding frame 17, a first guide rod 161 and a first spring 162, and the sliding frame 17 is connected to the casting mold 14, and the first guide rod 161 is vertically arranged on the mounting rod 15. On the rod 15, the sliding frame 17 is slidably installed on the first guide rod 161, and the first spring 162 is sleeved and installed on the first guide rod 161. When the pressure rod 18 is separated from the first limit baffle 6, the casting mold 14 is driven to automatically reset under the elastic force of the first spring 162. The casting mold 14 is connected with the pressure rod 18; multiple first limit baffles 6 are vertically corresponding to multiple cooling water tanks 9 one by one, the first limit baffle 6 is connected to the frame 1, and one side of the first limit baffle 6 is an upwardly tilted structure.

[0027] Multiple cooling water tanks 9 are installed on the frame 1, and multiple cooling water tanks 9 are located on the inner side of the transmission belt 2; multiple cooling water tanks 9 are installed with cooling devices 10 and temperature sensors. The set temperature sensor can monitor the internal water temperature of the cooling water tank 9 in real time and feed back the data to the controller 8. When the temperature exceeds the set range value, the controller 8 controls the cooling device 10 to work until the internal water temperature of the cooling water tank 9 drops to within the set range.

[0028] An automatic unloading mechanism 4 is installed at the upper end of the frame 1. The automatic unloading mechanism is used to inject molten iron into the interior of the casting mold 14. The automatic unloading mechanism 4 includes a heating box for heating the molten iron, a discharge pipe connected to the heating box, and an electrically controlled valve installed on the discharge pipe.

[0029] The upper end of the frame 1 is connected to a vibration frame 20, on which a vibration motor is installed. When the casting mold 14 moves to the position of the vibration frame 20, the vibration frame 20 contacts the side wall of the casting mold 14, and the vibration motor is started. The vibration generated by the vibration motor is transmitted to the vibration frame 20. When the casting mold 14 contacts the vibration frame 20, the vibration is transmitted to the casting mold 14, thereby eliminating bubbles in the molten iron inside the casting mold 14 and improving the production quality of the product.

[0030] Two support plates 13 are connected to the frame 1. The two support plates 13 are in contact with the top of the inner side surface of the transmission belt 2. The support plates 13 can support the upper end of the transmission belt 2 to prevent the transmission belt 2 from falling.

[0031] In this embodiment, a power assembly is set up to drive the transmission belt 2 to rotate, thereby driving multiple casting molds 14 to move. When the casting mold 14 moves to the position directly below the automatic unloading mechanism 4, molten iron is injected into the inner side of the casting mold 14, and the transmission belt 2 continues to rotate. When the pressure rod 18 begins to contact the inclined surface of the first limit baffle 6, the pressure rod 18 is forced to start moving downward, that is, driving the casting mold 14 to move downward. The casting mold 14 moves downward through the perforation 201 and is placed on the inner side of the cooling water tank 9. The casting mold 14 and the cast piston are cooled by the cooling water set inside the cooling water tank 9. Among them, multiple cooling water tanks 9 can be set, and the water temperature inside the multiple cooling water tanks 9 is reduced successively. The finished product is cooled by a step-by-step cooling method, thereby avoiding the adverse effects on the product and the casting mold 14 caused by excessively fast cooling speed.
