Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy casting processing technology, and in particular to a burr-free aluminum alloy casting edge trimming mold. Background Technology

[0002] Burr-free aluminum alloy casting trimming dies are special dies designed specifically for trimming, removing burrs, and shaping aluminum alloy castings during the production process. During the casting process, aluminum alloy castings usually produce some excess material (burrs) on the edges, openings, or other parts of the casting. These burrs not only affect the appearance of the casting but may also affect its assembly accuracy, performance, and subsequent processing. Therefore, using trimming dies for burr removal and shaping is an important part of aluminum alloy casting processing.

[0003] However, existing burr-free aluminum alloy casting trimming dies lack effective clamping components when trimming cylindrical aluminum alloy castings. Due to their relatively smooth and symmetrical shape, cylindrical aluminum alloy castings are prone to instability such as wobbling, tilting, or rotation during the cutting process without proper clamping. This instability not only causes the aluminum alloy casting to shift position during cutting, reducing cutting accuracy, but may also leave uneven cutting marks or burrs on the aluminum alloy surface, affecting the product's appearance quality and the accuracy of subsequent processing. In addition, the wobbling of the aluminum alloy casting during processing may also cause additional friction and wear to the die's blades or punches, reducing the die's service life and processing efficiency.

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] Example 1, please refer to Figure 1-7This utility model provides a technical solution: a burr-free aluminum alloy casting edge trimming mold, including a device body 1, a gantry frame 101 fixedly installed on the top of the device body 1, a first electric push rod 102 fixedly embedded in the top side of the inner side of the gantry frame 101, and a ring cutter 103 fixedly installed at the bottom of the first electric push rod 102. It also includes: an edge trimming table 104 fixedly installed on the top of the device body 1; and a clamping member 105 fixedly installed on the top of the device body 1, with a ring cutter 103 fixedly installed on the bottom side of the inner wall of the clamping member 105. The device includes a second electric push rod 106; a first push block 107, fixedly mounted on the top of the second electric push rod 106; wherein the first push block 107 is slidably connected inside the clamping member 105, and the second electric push rod 106 can drive the first push block 107 to slide up and down inside the clamping member 105; multiple connecting posts 108 are slidably connected inside the clamping member 105; multiple second push blocks 109 are fixedly mounted on opposite sides of the connecting posts 108; and a cylindrical casting 115 is movably embedded. Inside the cutting table 104, multiple second pushing blocks 109 are slidably connected to the outer surface of the first pushing block 107. Clamping plates 110 are fixedly installed on opposite sides of multiple connecting columns 108, soft pads 111 are fixedly installed on opposite sides of multiple clamping plates 110, and two first support columns 112 are fixedly installed on opposite sides of multiple clamping plates 110. The soft pads 111 are located inside the cylindrical casting 115, and second support columns 112 are slidably connected to the outer surfaces of the multiple first support columns 112. 13. Multiple second support columns 113 are fixedly installed on the outer surface of the clamping member 105 on opposite sides, and multiple first support columns 112 are fixedly installed on opposite sides with return springs 114. The other ends of multiple return springs 114 are fixedly installed on the inner wall of the second support column 113. The multiple return springs 114 can extend and retract inside the second support column 113. The outer surface of the clamping member 105 is movably fitted with a push plate 2, and the top of the push plate 2 is movably connected to the bottom of the cylindrical casting 115.

[0045] In this embodiment, during use, the operator first places the cylindrical casting 115 inside the cutting table 104 on the device body 1, and positions it outside the soft pad 111. Then, the operator presses down on the cylindrical casting 115 so that its bottom can fit against the top of the push plate 2. Then, the operator activates the second electric push rod 106 through its power supply system, so that when it extends, it can push the first push block 107 to slide upward inside the clamping member 105. When the first push block 107 slides upward, it can fit against the inner side of the second push block 109 and move. Then, the first push block 107 can squeeze the second push block 109 outward. When the second push block 109 is squeezed, the connecting column 108 can push the clamping plate 110 outward. Then, the clamping plate 110 can drive the soft pad 111 to fit against the inner wall of the cylindrical casting 115 to clamp it. When the clamping plate 110 moves, it can pull... The first support column 112 slides outward inside the second support column 113, and at the same time, the first support column 112 can pull the return spring 114 to extend. After the cylindrical casting 115 is clamped, the personnel can start the first electric push rod 102 through the power supply system inside the gantry frame 101, so that when it extends, it can drive the ring cutter 103 to descend. Then, the ring cutter 103 can be used to cut the cylindrical casting 115. The structure of the clamping plate 110 and the ring cutter 103 not only makes the soft pad 111 fit against the inner wall of the cylindrical casting 115, ensuring the stability of the casting during the cutting process, but also effectively avoids the casting from shaking or tilting during the cutting process, which would affect the cutting accuracy and surface quality of the casting. At the same time, the setting of the soft pad 111 can prevent the clamping plate 110 from directly contacting the inner wall of the cylindrical casting 115 during clamping, thus preventing scratches on the inner wall.

[0046] Example 2, as Figure 1-7 As shown, sliders 201 are fixedly installed on both sides of the push plate 2. One slider 201 is internally threaded with a screw 202. The bottom outer surface of the screw 202 is movably embedded inside the device body 1, and the top of the screw 202 is movably embedded in the bottom of the cutting table 104. A motor 203 is fixedly connected to the bottom of the screw 202. The other slider 201 is internally slidably connected with a slide rod 204. The bottom of the slide rod 204 is fixedly installed on the top of the device body 1, and the top of the slide rod 204 is fixedly installed on the bottom of the cutting table 104. The motor 203 is rigidly connected to the bottom of the device body 1 through a support frame.

[0047] In this embodiment, after the cylindrical casting 115 is trimmed, the operator can start the motor 203 through its power supply system. During operation, the motor 203 drives the screw 202 via its output shaft, which in turn drives the right slider 201. As the right slider 201 moves, the left slider 201, in conjunction with the sliding rod 204, causes the push plate 2 to rise. As the push plate 2 rises, it moves to fit against the outer surface of the clamping member 105, thus pushing the cylindrical casting 115 upwards inside the trimming table 104. This facilitates unloading by the operator. Furthermore, the push plate 2 and sliding rod 204 structure allow the cylindrical casting 115 to be pushed out of the trimming table 104, enabling the operator to easily complete the unloading operation, reducing physical labor intensity, and improving worker comfort and work efficiency.

[0048] Working principle: In use, the operator first places the cylindrical casting 115 inside the cutting table 104 on the main body 1 of the device, and places it outside the soft pad 111. Then, the operator presses down on the cylindrical casting 115 so that its bottom can fit against the top of the push plate 2. Then, the operator starts the second electric push rod 106 through the power supply system, so that when it extends, it can push the first push block 107 to slide upward inside the clamping member 105. When the first push block 107 slides upward, it can fit against the inner side of the second push block 109 and move. Then, the first push block 107 can squeeze the second push block 109 outward. When the second push block 109 is squeezed, the connecting column 108 can push the clamping plate 110 outward. Then, the clamping plate 110 can drive the soft pad 111 to fit against the inner wall of the cylindrical casting 115 to clamp it. When the clamping plate 110 moves, it can pull... The first support column 112 slides outward inside the second support column 113, and at the same time, the first support column 112 can pull the return spring 114 to extend. After the cylindrical casting 115 is clamped, the personnel can start the first electric push rod 102 through the power supply system inside the gantry frame 101, so that when it extends, it can drive the ring cutter 103 to descend. Then, the ring cutter 103 can be used to cut the cylindrical casting 115. Through the structure of the clamping plate 110 and the ring cutter 103, not only does the soft pad 111 fit against the inner wall of the cylindrical casting 115, ensuring the stability of the casting during the cutting process, it effectively avoids the casting from shaking or tilting during the cutting process, affecting the cutting accuracy and surface quality of the casting. At the same time, the setting of the soft pad 111 can prevent the clamping plate 110 from directly contacting the inner wall of the cylindrical casting 115 during clamping, thus preventing scratches on its inner wall.

[0049] In use, after the cylindrical casting 115 is trimmed, the operator can start the motor 203 through its power supply system. During operation, the motor 203 drives the screw 202 via its output shaft, which in turn drives the right slider 201. As the right slider 201 moves, the left slider 201, in conjunction with the sliding rod 204, causes the push plate 2 to rise. As the push plate 2 rises, it moves to fit against the outer surface of the clamping member 105, thus pushing the cylindrical casting 115 upwards inside the trimming table 104. This facilitates unloading. Furthermore, the push plate 2 and sliding rod 204 structure allows the cylindrical casting 115 to be pushed out of the trimming table 104, enabling operators to easily complete the unloading operation, reducing physical labor intensity, and improving worker comfort and work efficiency.

[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
