Description

Technical Field

[0001] This utility model relates to the field of edge trimming equipment technology, specifically an edge trimming equipment for aluminum die casting processing. Background Technology

[0002] In aluminum die casting, trimming equipment refers to specialized mechanical equipment used to remove excess waste (such as burrs and flash from gates, overflow channels, venting channels, and parting surfaces) from die casting blanks. This process is commonly referred to as "trimming," "deburring," or "flaking." It is a crucial and common step in the post-processing of aluminum die casting production, with the aim of obtaining parts that meet dimensional requirements and have a clean appearance for subsequent processing (such as CNC finishing, grinding, painting, etc.) or direct assembly.

[0003] In existing technology, hydraulic trimming machines are typically used for trimming aluminum die castings. The huge thrust generated by the hydraulic system drives the slide to move. When the slide descends, it causes the upper and lower molds to close. The precision molds then stamp and remove the waste material from the aluminum die casting. However, in actual use, the trimmed aluminum die casting is embedded outside the lower mold. When disassembling it, one side needs to be pried up. This method of prying up one side for disassembly can easily cause bending when disassembling some thinner aluminum die castings. Therefore, it is necessary to improve the aluminum die casting processing trimming equipment to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an edge-trimming device for aluminum die-casting parts to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum die-casting part processing and trimming device, comprising a trimming device body and a control button for operation control. An auxiliary lifting mechanism is provided on the top of the trimming device body. A support rod is fixedly installed on the top of the trimming device body. A top plate is fixedly installed on the top of the support rod. A hydraulic rod is fixedly installed inside the top plate. A sliding plate is fixedly installed at the bottom of the output end of the hydraulic rod. An upper trimming mold is fixedly installed at the bottom of the sliding plate. Holes are opened at corresponding positions of the sliding plate and the support rod, and the support rod is slidably installed inside the holes opened inside the sliding plate. The auxiliary lifting mechanism includes a support frame, which is fixedly installed on the top of the cutting equipment body. A lower die is fixedly installed on the top of the support frame. An abutment column is slidably installed inside the lower die. An arc-shaped plate is fixedly installed at the bottom of the abutment column. A spring is fixedly installed on the top of the arc-shaped plate. A motor is fixedly installed on the top of the cutting equipment body. A rotation limit seat is provided on the inner side of the top of the support frame. A cam rod is rotatably installed inside the rotation limit seat on the inner side of the top of the support frame. A transmission roller is fixedly installed outside the cam rod. A transmission belt is driven by the transmission roller.

[0006] Preferably, the spring is disposed outside the abutment post, and the end of the spring away from the arc head plate is fixedly installed on the top inner side of the lower mold pad.

[0007] Preferably, the lower mold has a hole inside, and the abutting post is slidably installed inside the hole inside the lower mold, and the hole inside the lower mold is symmetrically distributed at the four corners of the top of the lower mold.

[0008] Preferably, there are two cam rods, and the back of the left cam rod is fixedly installed to the front of the motor's drive shaft.

[0009] Compared with the prior art, this utility model provides an edge trimming device for aluminum die castings, which has the following advantages: This aluminum die-casting processing and trimming equipment, through its auxiliary lifting mechanism, utilizes the transmission of a cam rod to push the aluminum die-casting upwards away from the lower mold after trimming, thus avoiding the inconvenience of disassembling the aluminum die-casting with one side tilted up. The synchronous pushing method at all four corners can prevent the aluminum die-casting from bending and effectively reduce the scrap rate of trimming. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0013] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0014] Example: Please see Figure 1-4This utility model provides a technical solution: an aluminum die casting processing trimming equipment, including a trimming equipment body 1 and a control button 8 for controlling operation. An auxiliary lifting mechanism 2 is provided on the top of the trimming equipment body 1. A support rod 3 is fixedly installed on the top of the trimming equipment body 1. A top plate 4 is fixedly installed on the top of the support rod 3. A hydraulic rod 5 is fixedly installed inside the top plate 4. A sliding plate 6 is fixedly installed at the bottom of the output end of the hydraulic rod 5. A trimming upper mold 7 is fixedly installed at the bottom of the sliding plate 6.

[0015] Furthermore, holes are provided at corresponding positions of the slide plate 6 and the support rod 3, and the support rod 3 is slidably installed inside the holes provided inside the slide plate 6. The sliding of the slide plate 6 is limited by the support rod 3, so that the lower position of the upper cutting mold 7 can correspond to the lower mold 22, thereby accurately cutting the aluminum die casting.

[0016] Furthermore, the auxiliary lifting mechanism 2 includes a support frame 21, which is fixedly installed on the top of the cutting equipment body 1. A lower mold 22 is fixedly installed on the top of the support frame 21. An abutment column 23 is slidably installed inside the lower mold 22. An arc head plate 24 is fixedly installed at the bottom of the abutment column 23. A spring 25 is fixedly installed on the top of the arc head plate 24. A motor 26 is fixedly installed on the top of the cutting equipment body 1. A rotation limit seat is provided on the inner side of the top of the support frame 21. A cam rod 27 is rotatably installed inside the rotation limit seat provided on the inner side of the top of the support frame 21. A transmission roller 28 is fixedly installed on the outside of the cam rod 27. A transmission belt 29 is driven on the outside of the transmission roller 28. Through the auxiliary lifting mechanism 2, after the cutting is completed, the abutment column 23 can be pushed out of the four corners of the aluminum die casting by the transmission of the cam rod 27, which facilitates its disassembly.

[0017] Furthermore, the spring 25 is set outside the abutment post 23, and the end of the spring 25 away from the arc head plate 24 is fixedly installed on the top inner side of the lower mold 22. By utilizing the elastic force of the spring 25, the abutment post 23 can be normally reset and return to its original position after being pushed, so as to avoid affecting the placement of the next batch of aluminum die castings.

[0018] Furthermore, the lower mold 22 has holes inside, and the abutment post 23 is slidably installed inside the holes inside the lower mold 22. The holes inside the lower mold 22 are symmetrically distributed at the four corners of the top of the lower mold 22. The evenly distributed symmetrical holes can make the force points of the aluminum die casting evenly distributed, so that it can be pushed out smoothly.

[0019] Furthermore, there are two cam rods 27, and the back of the left cam rod 27 is fixedly installed to the front of the drive shaft of the motor 26, so that the cam rod 27 can be driven to rotate by the output end of the motor 26, thereby causing the abutment column 23 to rise.

[0020] In actual operation, when this device is used to trim the edges of aluminum die castings, the aluminum die casting to be processed is first placed above the lower mold 22 to ensure it fits properly. Then, the output end of the hydraulic rod 5 is driven by the control button 8 to lower the slide plate 6, causing the upper mold 7 to press down and trim the edge of the trimming device body 1. After trimming, the output end of the motor 26 rotates once by pressing the control button 8. Through the transmission of the transmission roller 28 and the transmission belt 29, the two cam rods 27 rotate synchronously and push the abutment post 23 upward through the arc head plate 24. At this time, the aluminum die casting moves upward and can be directly removed. When the cam rod 27 resets, the elastic force of the spring 25 makes the abutment post 23 reset, preventing the next aluminum die casting from being unable to be properly placed.

[0021] It should be further explained that the edge-cutting device body 1 in this application is designed for cutting square aluminum die-cast parts. If it is necessary to cut aluminum die-cast parts of different shapes, the edge-cutting device body 1 of a specific shape can be customized according to different processed parts. At the same time, in order to avoid the cam rod 27 rotating asynchronously due to friction slippage, the transmission roller 28 and transmission belt 29 used in this application are made of rubber toothed material. The tooth groove meshing completely avoids slippage. The control method of the motor 26 adopts the prior art. It is electrically installed with the edge-cutting device body 1 through wires and controlled by the integrated control button 8. The control method of the hydraulic rod 5 is also controlled by the control button 8. All of these adopt the prior art.

[0022] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
