Description

Technical Field

[0001] The utility model relates to the technical field of casting equipment, in particular to energy-saving melting and casting equipment. Background Art

[0002] In modern industrial production, casting machines are capable of efficiently producing large quantities of castings in batches, meeting the demands of large-scale production. However, melt casting, which converts raw metal into castings through smelting and casting, still has its advantages and necessity. The reasons are as follows: Diversity: Melting casting can process a wide range of metals and alloys, including aluminum, copper, iron, steel, and their alloys. Flexibility: Compared with casting machines, melt casting offers greater flexibility in material selection and recipe adjustment. Complex castings: Melting casting may be more suitable for castings with complex shapes and special structures. Small-scale production: While casting machines excel at mass production, melt casting may have advantages for small-scale or customized production. Equipment investment: The high purchase and installation costs of casting machines can be a significant burden for small and medium-sized enterprises or startups. Melting casting, on the other hand, requires relatively simple equipment, with a lower investment cost, making it more affordable. Production cycle: In some cases, melt casting can have a shorter production cycle. Especially for small batches or urgent orders, melt casting can quickly respond to market demand and shorten delivery times.

The flipping mechanism includes four electric push rods 59. A hanging ear is respectively provided on both sides of the upper end and the lower end of the crucible 58.

One end of the electric push rod 59 of the forward and backward moving mechanism is hinged to the connecting rod, and the other end is hinged to the top surface of the moving plate 56.

[0029] As the molten metal is consumed, the height of crucible 58 gradually increases, its tilt angle gradually widens, and the movable plate 56 of the vertical movement mechanism gradually rises. Simultaneously, the two electric push rods 59 above the tilting mechanism gradually extend, while the two electric push rods 59 below gradually retract. The vertical movement and tilting mechanisms allow for convenient adjustment of the height and tilt angle of crucible 58 based on molten metal consumption, ensuring smooth casting.

The electric push rod 59 is an industry standard component. The extension and retraction control of the electric push rod 59 is actually also the speed and direction control of the motor. It belongs to the existing technology and is not described in detail. The electric push rod, also known as a linear drive or push rod motor, is an electric drive device that converts the rotational motion of the motor into the linear reciprocating motion of the push rod. It mainly consists of a drive motor, a reduction gear, a screw, a nut, etc. When the motor starts, the speed is reduced and the torque is increased by the reduction gear, and then the screw is driven to rotate. The cooperation between the screw and the nut converts the rotational motion into linear motion, pushing the telescopic rod to perform the telescopic action. The reciprocating forward and backward motion of the push rod can be achieved by using the forward and reverse rotation of the motor.

[0033] During operation, the mold to be cast is placed at the beginning of the conveyor chain 1, and the mold moves forward with the conveyor chain 1. Then, the heat-insulating door 3 at the front end of the conveying channel 21 at the beginning of the conveyor chain 1 is opened. After the mold enters the conveying channel 21, the front heat-insulating door 3 is closed, and the rear heat-insulating door 3 is opened. The mold then enters the heat-insulating cover 2 below the melting and casting mechanism 5 for casting. After the casting is completed, the heat-insulating door 3 at the front end of the conveying channel 21 at the end of the conveyor chain 1 is first opened. After the mold enters the conveying channel 21, the front heat-insulating door 3 is closed, and the rear heat-insulating door 3 is opened. After the mold completely exits the conveying channel 21, the heat-insulating door 3 at the rear end of the conveying channel 21 is closed, completing one casting. By arranging the melting and casting mechanism 5 in the heat-insulating cover 2, the casting equipment can reduce energy consumption. By arranging a conveying channel 21 on both sides of the heat-insulating cover 2, the mold to be cast enters from the conveying channel 21 on one side for casting, and exits from the conveying channel 21 on the other side after the casting is completed, so that the casting work can be continued.
