Description

Technical Field

[0001] This utility model relates to the field of automotive mold processing technology, specifically to an electromagnetic fixing device for processing automotive metal block molds. Background Technology

[0002] Automotive metal block molds are indispensable key tools in automobile manufacturing. Made of high-strength metal materials (mainly steel and aluminum alloys), they have a fixed block structure and are used to mold various automotive parts. During mold processing, the mold needs to be fixed in place; any displacement or movement can directly lead to dimensional deviations and surface defects in the parts. Currently, traditional clamps commonly used in the industry generally suffer from cumbersome installation and disassembly, time-consuming positioning and adjustment, and the potential for crushing damage to the mold surface. To solve this problem, electromagnet fixing solutions have been gradually adopted. When an electromagnet is energized, it generates a strong magnetic force to attract and fix the mold; when the electromagnet is de-energized, the magnetic force disappears, and the fixation can be easily released, balancing convenience and protection for the mold.

[0003] However, in actual use, the electromagnet-fixed mold solution has the following problems: a large amount of metal debris is generated during the processing. When the electromagnet is energized, it will simultaneously attract the debris to the mold surface and surrounding area, causing the debris to accumulate continuously. This not only affects the mold processing quality but also increases the workload of subsequent cleaning and maintenance. Utility Model Content

[0004] Therefore, this utility model provides an electromagnetic fixing device for processing automotive metal block molds, which can effectively prevent the accumulation of debris from affecting mold processing, thus effectively ensuring the quality of mold processing and reducing the workload of personnel cleaning.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electromagnetic fixing device for processing automotive metal block molds, comprising an electromagnetic fixing component fixed on the worktable of a mold processing equipment, the electromagnetic fixing component comprising a hollow base, an opening at the top and front end of the hollow base, an electromagnet fixed at the center of the top of the hollow base, and an automotive metal block mold fixed to the top of the electromagnet.

[0006] The hollow base has multiple electromagnets fixed on both sides of the electromagnet one at its top, which are used to adsorb the debris generated during processing.

[0007] Both sides of the top of the hollow base are equipped with debris cleaning mechanisms for cleaning debris generated during the processing of electromagnet one and electromagnet two.

[0008] Furthermore, chip removal openings are formed between adjacent electromagnets, between electromagnet 2 and electromagnet 1, and between electromagnet 2 and the inner wall of the hollow base, through which the processing debris falls into the hollow base.

[0009] Furthermore, a U-shaped baffle is fixed at the top edge of the hollow base to block the debris generated during processing on the hollow base.

[0010] Furthermore, the debris cleaning mechanism includes an electromagnet three located on the top of the hollow base. The outer side of the electromagnet three is driven to move by an electric push rod, which is fixed to the side of the U-shaped baffle. The bottom surface of the debris cleaning mechanism, the top surface of the hollow base, the top surface of electromagnet one, and the top surface of electromagnet two are all flush, which facilitates the movement of electromagnet three to clean the debris on electromagnet one and electromagnet two.

[0011] Furthermore, mounting blocks are fixed on both the front and rear sides of the three top ends of the electromagnet. The front mounting block is slidably connected to the inner front wall of the U-shaped baffle via a slide rail, and the rear mounting block is slidably connected to the mold processing equipment via a slide rail.

[0012] Furthermore, a collection drawer is slidably provided inside the hollow base, and the collection drawer extends to the front end of the hollow base. The processing debris falls into the collection drawer of the hollow base through the debris discharge port for collection.

[0013] Furthermore, an electromagnet is fixed to the bottom of the inside of the collection drawer to facilitate the attraction and fixation of debris in the collection drawer.

[0014] Furthermore, tactile switches are fixed on both sides of the inner wall of the U-shaped baffle. When the mounting block contacts the tactile switch, the electromagnet installed on the mounting block is turned off. When the mounting block is not in contact with the tactile switch, the electromagnet installed on the mounting block is energized.

[0015] This utility model has the following advantages: This invention installs two electromagnets around an electromagnet one that is used to fix the mold, and forms chip discharge ports between adjacent electromagnets two, between electromagnet two and electromagnet one, and between electromagnet two and the inner wall of the hollow base. During processing, some chips fall into the hollow base through the chip discharge ports and are collected, effectively reducing the accumulation of chips around the mold. At the same time, a chip cleaning mechanism is provided to clean the chips around the mold during the mold processing, further reducing the accumulation of chips around the mold. This effectively avoids chip accumulation affecting the mold processing and thus effectively ensures the quality of mold processing. In addition, the debris cleaning mechanism also supports the comprehensive and automatic cleaning of debris on the top of the hollow base after the mold processing is completed, effectively reducing the workload of personnel cleaning.

[0017] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Refer to the instruction manual appendix Figure 1-6 This utility model provides an electromagnetic fixing device for processing automotive metal block molds, including an electromagnetic fixing component fixed on the worktable of the mold processing equipment 1. The electromagnetic fixing component includes a hollow base 2 with an opening at the top and front end. An electromagnet 3 is fixed at the center of the top of the hollow base 2. The automotive metal block mold is placed on the top of the electromagnet 3. When the electromagnet 3 is energized, the automotive metal block mold is fixed on the top of the electromagnet 3. A collection drawer 7 is slidably provided inside the hollow base 2, and the collection drawer 7 extends to the front end of the hollow base 2.

[0019] Multiple electromagnets 4 are fixed to both sides of the top of the hollow base 2, located at the top of the electromagnet 3. Chip-falling openings are formed between adjacent electromagnets 4, between electromagnets 4 and 3, and between electromagnets 4 and the inner wall of the hollow base 2. A U-shaped baffle 5 is fixed to the edge of the top of the hollow base 2 to block chips generated during processing. In actual use, the mold processing equipment 1, electromagnets 3 and 4 are all controlled by the control system of the mold processing equipment 1.

[0020] In use, the car metal block mold is first placed on top of electromagnet 3. Then, both electromagnet 3 and electromagnet 4 are energized and started. Electromagnet 3 generates a magnetic field to attract and fix the mold. Then, the mold processing equipment 1 processes the mold. During processing, some of the debris is attracted to electromagnet 4, and the other part falls into the collection drawer 7 of the hollow base 2 through the debris discharge port. This not only achieves convenient fixation of the mold, but also effectively prevents the debris generated during processing from splashing outward, thereby effectively reducing the workload of personnel cleaning.

[0021] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, both sides of the top of the hollow base 2 are provided with debris cleaning mechanisms 6, which are used to clean debris generated during processing on electromagnets 1 and 2. Specifically, the debris cleaning mechanism 6 includes electromagnet 3 61 located on the top of the hollow base 2. The outer side of electromagnet 3 61 is driven by an electric push rod 62, which is controlled by the control system of the mold processing equipment 1.

[0022] The electric push rod 62 is fixed to the side of the U-shaped baffle 5. The bottom surface of the debris cleaning mechanism 6, the top surface of the hollow base 2, the top surface of electromagnet 1 3, and the top surface of electromagnet 2 4 are all flush, which makes it easy for electromagnet 3 61 to move and clean the debris on electromagnet 1 3 and electromagnet 2 4.

[0023] The electromagnet 61 has mounting blocks 63 fixed on both the front and rear sides of its top end. The mounting block 63 on the front side is slidably connected to the inner front wall of the U-shaped baffle 5 via a slide rail, and the mounting block 63 on the rear side is slidably connected to the mold processing equipment 1 via a slide rail, which facilitates the sliding of the electromagnet 61.

[0024] Tactile switches 9 are fixed on both inner side walls of the U-shaped baffle 5. Both the electromagnet 61 and the tactile switches 9 are controlled by the control system of the mold processing equipment 1. The tactile switches 9 are normally closed switches. The core working principle of a normally closed switch is that it is normally closed and opens upon triggering. When not energized, the contacts remain closed to conduct the circuit. When triggered by an external force or signal, the contacts open to cut off the circuit. After the trigger is released, it automatically resets and closes. This ensures that when the mounting block 63 is in contact with the tactile switch 9, the electromagnet 61 mounted on the mounting block 63 is closed; when the mounting block 63 is not in contact with the tactile switch 9, the electromagnet 61 mounted on the mounting block 63 is energized.

[0025] This invention offers two methods for cleaning debris: I. Cleaning during processing: First, electromagnets 3 and 61 are located on both sides of the mold. During processing, the electric push rods 62 of the two sets of chip cleaning mechanisms 6 drive the two electromagnets 3 and 61 to slide along the top of electromagnet 2 and 4. At this time, the electromagnets 3 and 61 leave the tactile switch 9. The two electromagnets 3 and 61 are energized to generate a magnetic field. On the one hand, the electromagnets 3 and 61 can push the chips on electromagnet 2 and 4 into the chip dropper or fall into the collection drawer 7 through the chip dropper. On the other hand, the electromagnets 3 and 61 can attract chips. When the electromagnets 3 and 61 move to the outside of the mold, they stop moving. Then the electric push rods 62 drive the electromagnets 3 and 61 to reset. When resetting, the electromagnets 3 and 61 trigger the tactile switch 9. The electromagnets 3 and 61 are turned off, and the chips attracted on them fall into the collection drawer 7 through the chip dropper. By cleaning debris around the mold during the mold processing, the accumulation of debris can be effectively prevented from affecting the mold processing, thus effectively ensuring the quality of mold processing.

[0026] 2. Cleaning after processing: Turn off electromagnet 3 and electromagnet 4, remove the processed mold from electromagnet 3, and then a set of debris cleaning mechanisms 6 on one side of the hollow base 2 will work. The electric push rod 62 of the debris cleaning mechanism 6 will drive electromagnet 3 61 to slide along the top of electromagnet 2 4. At this time, electromagnet 3 61 will leave the tactile switch 9. Electromagnet 3 61 will generate a magnetic field when energized. On the one hand, electromagnet 3 61 can push the debris on electromagnet 2 4 to fall into the collection drawer 7 through the debris discharge port. On the other hand, electromagnet 3 61 can attract debris. When electromagnet 3 61 moves to the other side of the hollow base 2, it will stop moving. Then the electric push rod 62 will drive electromagnet 3 61 to reset. When it resets, electromagnet 3 61 will trigger the tactile switch 9, and electromagnet 3 61 will be turned off. The debris attracted on it will fall into the collection drawer 7 through the debris discharge port. By fully and automatically cleaning the top of the hollow base 2 after the mold processing is completed, the workload of manual cleaning is reduced.

[0027] In actual use, the magnetic strength settings of electromagnet 13 and electromagnet 24 are different. Electromagnet 13 adopts a high magnetic flux density design, such as 1.2-1.5T, to ensure sufficient attraction force on the workpiece and prevent workpiece displacement. Electromagnet 24 and electromagnet 361 are designed with a magnetic flux density of 0.3-0.5T, which can only attract debris, avoiding excessive attraction force that would make debris difficult to clean, while not affecting the fixation of the workpiece.

[0028] Furthermore, such as Figure 5 As shown, an electromagnet 8 is fixed at the bottom of the inside of the collection drawer 7 to attract and fix the debris in the collection drawer 7, thereby preventing the debris from escaping when the collection drawer 7 is pulled out.

[0029] In actual use, the electromagnet 48 is not controlled by the control system of the mold processing equipment 1. Instead, a power supply and controller for the electromagnet 48 are installed separately on the collection drawer 7. Thus, when cleaning the inside of the collection drawer 7, the electromagnet 48 is turned off after the collection drawer 7 is pulled out, making it easy to pour out the debris collected in the collection drawer 7.

[0030] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
