Description

Technical Field

[0002] A piston engine, also known as a reciprocating engine, is an engine that uses one or more pistons to convert pressure into rotational kinetic energy. Currently, the pistons of engines are made by automatic casting equipment in conjunction with mold casting.

If a heat-conducting component is directly set at the bottom of the casting mold to improve the heat dissipation effect, it is easy to cause cooling before casting is completed, affecting the solidification effect, and the piston is relatively tight to the mold after molding, which is not convenient for demolding.

[0027] In this embodiment, the connecting plate 2022 is pushed up by the cooling component 201, and the connecting plate 2022 drives the tooth plate 2023 and the gear 2032 to transmit, so that the gear 2032 drives the screw 2031 and the petal cam 2033 to rotate, the petal cam 2033 squeezes the ball 208 to move, and the ball 208 drives the side mold 104 to move, and the side mold 104 drives the first spring 1034 to deform through the sliding rod 1035. When the convex surface of the petal cam 2033 is away from the ball 208, the first spring 1034 drives the side mold 104 to reset until the petal cam 2033 is pressed against the ball 208. The petal cam 2033 squeezes the ball 208 again to drive the side mold 104 to move, so that the petal cam 2033 cooperates with the first spring 1034 to drive the side mold 104 to vibrate, thereby removing bubbles inside the casting material and improving the quality of the finished product. In addition, during the vibration process, the insulation layer 2051 is gradually separated from the heat dissipation column 108, thereby avoiding the solidification of the casting material and facilitating the elimination of bubbles. At the same time, before demolding, the side mold 104 can also be vibrated, thereby separating the piston product from the side mold 104 through vibration, which is convenient for demolding.

[0028] Working principle: During pouring, the first electric push rod 1031 extends and moves, so that the support frame 1032 drives the side mold 104 to move through the sliding rod 1035, and the upper mold 105 moves at the same time, so that the two adjacent side plates 1065 contact and generate extrusion, and at the same time, an extrusion movement occurs between the upper side plate 1065 and the stopper 107, so that the movable frame 1064 and the side mold 104 and the upper mold 105 move relative to each other, and at the same time, the second spring 1063 is deformed, so that the movable frame 1064 drives the positioning rod 1062 to move, and the positioning rod 1062 escapes from the positioning groove 1036, so that the upper mold 105 and the side mold 104 are docked and closed, and then the pouring material is injected into the side mold 104 through the pouring port of the upper mold 105; Then, the second electric push rod 2012 is controlled to push the carrier plate 2011 upward to move, and the carrier plate 2011 drives the radiator 2013 and the heat conducting column 2014 to move upward, and the carrier plate 2011 pushes the tooth plate 2023 upward, so that the tooth plate 2023 and the gear 2032 are transmitted, and the gear 2032 drives the screw rod 2031 to rotate, and the screw rod 2031 drives the petal cam 2033 to squeeze the ball 208 to move, and the ball 208 drives the side mold 104 to move, and the side mold 104 drives the first spring 1034 to deform through the sliding rod 1035. When the convex surface of the petal cam 2033 is away from the ball 208, the first spring 1034 drives the side mold 104 to reset, until the petal cam 2033 squeezes the ball 208 again to drive the side mold 104 to move, so that the first spring 1034 cooperates with the petal cam 2033 to realize the vibration of the side mold 104, and the vibration of the side mold 104 can eliminate the internal bubbles; During the rotation of the screw 2031, the screw 2031 also drives the threaded barrel 2034 to move, so that the threaded barrel 2034 drives the push plate 2056 to move through the roller 2035, and the push plate 2056 drives the thermal insulation layer 2051 to move, and the thermal insulation layer 2051 drives the fourth spring 2054 to deform through the sliding sleeve 2055, and the thermal insulation layer 2051 is separated from the heat dissipation column 108, so that the heat dissipation column 108 is exposed, and the heat conduction column 2014 is connected with the heat dissipation column 108 upward, and heat is conducted outward through the heat conduction mold 109 and the heat dissipation column 108, so that the heat conduction column 2014 and the heat conduction rod 2015 diffuse heat outward, and the heat dissipation speed can be accelerated in combination with the radiator 2013, which is conducive to the rapid molding of the piston product; After the piston product is formed, the second electric push rod 2012 is controlled to drive the carrier plate 2011 to move downward, so that the tooth plate 2023 is again downwardly transmitted with the gear 2032, and the side mold 104 is vibrated again. At the same time, the screw 2031 drives the threaded tube 2034 to retract, so that the fourth spring 2054 drives the sliding sleeve 2055 and the insulation layer 2051 to reset, so that the insulation layer 2051 closes the heat dissipation column 108, and the first electric push rod 1031 is controlled to drive the support frame 1032 to retract, so that the side mold 104 and the upper mold 105 are separated, so that the piston product can be demolded.
