Description

Technical Field

[0001] This invention belongs to the field of copper and aluminum casting technology, specifically relating to a preparation device and testing method for aluminum-copper alloy shells under investment casting. Background Technology

[0002] Investment casting typically involves creating a pattern from a fusible material, covering the pattern surface with several layers of refractory material to form a shell, then melting the pattern and removing it from the shell to obtain a mold without a parting line. After high-temperature firing, the mold can be filled with sand and poured. This method is frequently used in the manufacture of aluminum and copper alloy shells.

[0003] Furthermore, existing equipment for preparing aluminum-copper alloy shells under investment casting involves manually pouring molten aluminum into the injection mold or transferring it to the mold using a robotic arm. However, these methods result in aluminum waste, and changing molds is cumbersome when casting different aluminum-copper shells. Consequently, the equipment is not very practical and has low production efficiency. Moreover, the testing and analysis of the preparation benefits of existing equipment are inaccurate. Therefore, this invention proposes an equipment for preparing aluminum-copper alloy shells under investment casting and its testing method. Summary of the Invention

[0004] The purpose of this invention is to provide an apparatus for preparing aluminum-copper alloy shells by investment casting, so as to solve the problems of waste of molten aluminum and low production efficiency mentioned in the background art.

[0005] In a first aspect, the present invention provides an apparatus for preparing an aluminum-copper alloy shell by investment casting, comprising:

[0006] A smelting furnace body, wherein a rotating mechanism is provided on the smelting furnace body, and a casting mechanism for investment casting is provided on the rotating mechanism;

[0007] The investment casting mechanism includes an electric telescopic rod, which is fixedly connected to the investment casting mechanism. A casting feed frame is detachably mounted on the output end of the electric telescopic rod. An installation component is fixedly mounted on the casting feed frame. A transmission rod is rotatably inserted into the installation component. A threaded sleeve is threaded onto the outer surface of the transmission rod. A positioning plate is fixedly mounted on the threaded sleeve. A positioning fixture is fixedly mounted on the positioning plate. A second motor is fixedly mounted on the casting feed frame. A first synchronous pulley is fixedly mounted on the transmission rod. A second synchronous pulley is fixedly mounted on the output end of the second motor. A synchronous belt is mounted on the outer surfaces of the first and second synchronous pulleys. A mold placement frame is in contact with the positioning fixture in the middle.

[0008] In one possible implementation of the first aspect, the interior of the casting feed frame is hollow, the mold placement frame is used in conjunction with the casting feed frame, the melting furnace body is provided with a melting tank, and the mold placement frame is located directly above the melting tank.

[0014] I. In this invention, the casting feed frame is placed into molten aluminum, and the molten aluminum enters the mold placement frame through the feed hole for casting. Compared with the traditional manual casting method, this does not waste molten aluminum, saves resources, and improves the practicality of the overall device.

[0015] Second, the second motor drives the second synchronous pulley to rotate, which in turn drives the first synchronous pulley to rotate via the synchronous belt, thereby driving the transmission rod to rotate. This, in turn, drives a set of threaded sleeves to move relative to or away from each other, thereby driving a set of positioning fixtures to move relative to or away from each other, thus clamping and replacing different mold placement frames.

[0016] In a second aspect, the present invention provides a method for performing tests on an apparatus for preparing an aluminum-copper alloy shell under investment casting, comprising:

It includes a melting furnace body 1, a rotating mechanism 2 on the melting furnace body 1, and an investment casting mechanism 3 on the rotating mechanism 2. The investment casting mechanism 3 includes an electric telescopic rod 30. The rotating mechanism 2 can rotate at a certain angle in the horizontal direction.

[0046] Please see Figure 2 This is proposed as an embodiment of the present invention. Figure 1 A cross-sectional view of the casting feed frame structure is shown. The electric telescopic rod 30 is fixedly connected to the investment casting mechanism 3. The output end of the electric telescopic rod 30 is detachably mounted with a casting feed frame 31. A mounting part 32 is fixedly mounted on the casting feed frame 31. A transmission rod 33 is rotatably inserted into the mounting part 32. A threaded sleeve 38 is threaded onto the outer surface of the transmission rod 33. A positioning plate 39 is fixedly mounted on the threaded sleeve 38. A positioning clamp 311 is fixedly mounted on the positioning plate 39. A second motor 35 is fixedly mounted on the casting feed frame 31. The transmission rod 3... The first synchronous pulley 34 is fixedly sleeved on the upper part of the 3, and the second synchronous pulley 36 is fixedly sleeved on the output end of the second motor 35. The outer surfaces of the first synchronous pulley 34 and the second synchronous pulley 36 are covered with a synchronous belt 37. The positioning clamp 311 is in contact with the mold placement frame 314 in the middle. The casting feed frame 31 has a hollow structure inside. The mold placement frame 314 is used in conjunction with the casting feed frame 31. The melting furnace body 1 has a melting tank 11. The mold placement frame 314 is located directly above the melting tank 11 and can hold different molds to facilitate subsequent mold replacement.

[0047] Please see Figure 3 This is proposed as an embodiment of the present invention. Figure 2 The schematic diagram of the rotating rod structure shows that the rotating mechanism 2 includes a positioning member 20, on which a rotating rod 21 is rotatably inserted. A connecting plate 22 is fixedly installed on the rotating rod 21. The connecting plate 22 is fixedly connected to the electric telescopic rod 30. When the rotating rod 21 rotates, it can drive the connecting plate 22 to rotate, thereby driving the electric telescopic rod 30 to rotate through the connecting plate 22.

[0048] Please see Figure 4 This is proposed as an embodiment of the present invention. Figure 3The enlarged structural diagram at point A shows that a support base 23 is fixedly installed on the furnace body 1. The rotating rod 21 is rotatably installed on the support base 23. A transmission shaft 24 is rotatably inserted into the support base 23. The transmission shaft 24 is fixedly connected to the rotating rod 21.

The rotation adjustment of the rotating rod 21 is achieved through the transmission shaft 24.

[0049] The working principle and usage process of the aluminum-copper alloy shell preparation device for investment casting of the present invention are as follows: During the subsequent preparation of the aluminum-copper alloy shell, when all the solid aluminum has been melted into molten aluminum, the electric telescopic rod 30 is activated to move the casting feed frame 31 downwards until the center of the feed hole 313 is level with the molten aluminum. When the mold placement frame 314 is filled with molten aluminum, the electric telescopic rod 30 moves the casting feed frame 31 upwards and places it at rest until no more molten aluminum drips from the surface of the casting feed frame 31. Then, the first motor 26 is activated, which drives the second bevel gear 27 to rotate. 7 drives the first bevel gear 25 and the transmission shaft 24 to rotate, thereby driving the rotating rod 21 to rotate, which in turn drives the mold placement frame 314 to move horizontally until it moves to the placement position. Then, the first motor 26 is turned off, and the second motor 35 is started. The second motor 35 drives the second synchronous pulley 36 to rotate, which drives the first synchronous pulley 34 to rotate through the synchronous belt 37, which in turn drives the transmission rod 33 to rotate. A set of threaded sleeves 38 drives a set of positioning plates 39 to move in opposite directions until a set of positioning clamps 311 separates from the mold placement frame 314. Finally, the injection mold inside the mold placement frame 314 can be removed.
