Description

Technical Field

[0001] The utility model relates to the technical field of mold repair devices, in particular to an automatic inner hole grinding device for a steel injection mold. Background Art

[0002] In modern industrial production, especially in the steel manufacturing industry, steel injection molds are critical production tools whose quality and precision directly impact the final product. Due to high temperatures, high pressures, and frequent use, steel injection molds often develop defects such as wear, oxidation, and cracks on their inner surfaces. These defects not only shorten the mold's service life but also negatively impact the quality of the finished product. Therefore, regular grinding and maintenance of steel injection mold inner surfaces is crucial.

[0003] Some existing mold repair devices lack a system or container for collecting cooling water when in use. The cooling water will flow around the device or onto the ground, which will not only pollute the working environment but also cause corrosion or damage to the device.

[0004] For example, the announcement number CN208866898U discloses an inner hole repair device for a copper alloy tube and rod stretching die. The repair device of this patent adopts a working mode of counter-rotation of the workpiece and the tooling, which increases the grinding effect compared with traditional turning and drilling and milling; the design of the cooling nozzle can ensure fixed-point cooling of small parts, and at the same time prevent the cutting fluid from splashing and damaging the working environment; in addition to grinding the original size of the grinding tool, it can also enlarge the small-aperture mold, thereby making full use of the mold material and reducing production costs; this device adopts a low-cost vehicle-mounted modification, is easy to install and disassemble, and is easy to operate.

[0005] Although the above-mentioned repair device has many advantages, there are still some shortcomings in the treatment and discharge of cooling water. The above-mentioned repair device does not mention any system or container for collecting cooling water. In actual operation, after the cooling water is sprayed onto the repairing part through the cooling nozzle, it will flow around the lathe or on the ground, which may not only cause a slippery working environment and safety hazards, but may also cause corrosion or damage to the lathe and other equipment.

[0006] Therefore, it is necessary to invent a kind of automatic inner hole grinding device of steel injection mold to solve the above problems. Utility Model Content

[0035] In one aspect of this embodiment, a control panel 8 is installed on the front of the workbench 1, and a solenoid valve 9 is installed in the middle of one end of the drain pipe 6 on the outside of the workbench 1. The solenoid valve 9 is electrically connected to the control panel 8. Longitudinal linear modules 10 are installed on both sides of the top of the workbench 1, and support columns 11 are installed on the top of the slides of the two longitudinal linear modules 10. Horizontal linear modules 12 are installed on the tops of the two support columns 11. A No. 1 electric push rod 13 is installed at the bottom of the slide of the horizontal linear module 12, and a drive motor 14 is installed at the bottom of the No. 1 electric push rod 13. The bottom of the output shaft of the drive motor 14 is connected to a grinding drill bit 15 for transmission. The longitudinal linear module 10, the horizontal linear module 12, and the No. 1 electric push rod 13 are connected to the bottom of the output shaft of the drive motor 14 for transmission. The push rod 13 and the drive motor 14 are both electrically connected to the control panel 8. A water supply component 16 is provided on one side of the drive motor 14. A clip is installed on one side of the drive motor 14. The water supply component 16 includes a water supply pipe 17. The water supply pipe 17 is clipped with the clip. The top and bottom ends of the water supply pipe 17 are both provided with threaded interfaces. The threaded interface at the bottom end of the water supply pipe 17 is threadedly connected to a nozzle 18. Clamping mechanisms 19 are provided on both sides of the top of the workbench 1. The clamping mechanism 19 includes a No. 2 electric push rod 20. The No. 2 electric push rod 20 is electrically connected to the control panel 8.

[0036] Working principle of this utility model:

[0037] Refer to the instruction manual Figure 1-5 When using the present invention, first place the mold to be repaired at the top center of the storage seat 3 to ensure that the mold is stable and does not shake, and connect the threaded interface at the top of the water supply pipe 17 to the external cooling water delivery pipe to ensure that the connection is tight and leak-free;

[0038] The two second electric push rods 20 are activated through the control panel 8. The second electric push rods 20 push the clamping plate 21 toward the mold until the rubber anti-slip pads 22 on the clamping plate 21 fit tightly against the mold surface, thereby clamping and fixing the mold.

[0039] The two longitudinal linear modules 10 are activated through the control panel 8, so that their slides drive the support columns 11 and the transverse linear module 12 to move above the mold. Then, the transverse position of the grinding drill bit 15 is adjusted through the transverse linear module 12, and the vertical position of the grinding drill bit 15 is adjusted through the No. 1 electric push rod 13 to ensure that the grinding drill bit 15 is aligned with the inner hole of the mold surface. After confirming that the position of the grinding drill bit 15 is correct, the drive motor 14 is controlled by the control panel 8 to start working, and the grinding drill bit 15 rotates and slowly descends into the inner hole of the mold to grind and repair the inner hole of the mold;

[0040] At the same time, the valve of the cooling water delivery pipeline is opened, and the cooling water flows into the nozzle 18 through the water supply pipe 17 and is evenly sprayed on the grinding part to flush and cool the grinding process and prevent overheating and debris splashing;

[0041] Cooling water with debris flows down from the mold surface, passes through the storage seat 3 and enters the sunken water collection trough 2. The cooling water is filtered by the frame-shaped filter plate 7, and the debris is trapped on the filter plate. The clean cooling water flows into the water storage hopper 5 through the seepage trough 4. When the cooling water in the water storage hopper 5 accumulates to a certain amount, the solenoid valve 9 is opened through the control panel 8, and the cooling water in the water storage hopper 5 is discharged through the drain pipe 6 for subsequent treatment or recycling.

[0042] Shut down the equipment regularly, remove the frame filter plate 7, and clean the debris and impurities attached thereto to maintain the filtering effect.
