Description

Technical Field

[0001] The utility model relates to a limiting structure for grinding an aluminum die-casting mold, belonging to the technical field of aluminum die-casting molds. Background Art

[0002] Aluminum die-casting molds are tools used in aluminum alloy die-casting production, typically constructed from high-strength steel to withstand high-temperature and high-pressure environments. These molds rapidly inject molten aluminum alloy into the mold cavity, where it cools to form precision aluminum parts. Aluminum die-casting molds offer excellent wear and corrosion resistance, enabling the production of complex castings while ensuring dimensional accuracy and surface finish. Due to the inherent lightness and high strength of aluminum alloys, products manufactured using aluminum die-casting molds are widely used in a variety of industries, including automotive, electronics, and aerospace. They are highly sought after for their ability to effectively reduce production costs and improve efficiency.

[0003] During the grinding process of aluminum die-casting molds, a limiting structure is required to limit and fix them. In the existing technology, the limiting structure usually uses a cylinder to drive the clamp to move inward and then fix the mold. However, the above method can only limit the mold in the horizontal direction. Since the mold will vibrate after contacting the grinding head during the grinding process, only using horizontal limiting may cause the mold to undergo longitudinal displacement during the grinding process, thereby affecting the grinding quality.

[0004] Therefore, a limiting structure for grinding an aluminum die-casting mold is proposed. Utility Model Content

[0005] In view of this, the present invention provides a limiting structure for grinding aluminum die-casting molds to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0006] The technical solution of the utility model is achieved as follows: a limiting structure for grinding aluminum die-casting molds, comprising a processing table, the bottom of the processing table is fixedly connected with a pad plate on all sides, and a transmission assembly is provided at the middle end of the bottom of the processing table, wherein the transmission assembly includes a transmission box, and the transmission box is fixedly connected to the middle end of the bottom of the processing table, and the left and right sides of the inner cavity of the transmission box are movably connected with positive and negative threaded rods through bearings, and both sides of the surfaces of the positive and negative threaded rods are threadedly connected with threaded sleeves, and the top of the threaded sleeve is fixedly connected with a connecting plate, and a clamping assembly is provided on the inner side of the connecting plate, and the clamping assembly includes a U-shaped plate and a transverse clamping plate, the U-shaped plate is welded to the inner side of the connecting plate, and an electric slide is provided on the inner side of the U-shaped plate, and the electric slide is slidably connected to the electric sleeve on both sides of the surface of the electric slide, and the inner side of the electric sleeve is fixedly connected with a connecting rod, and the inner side of the connecting rod is welded with a longitudinal clamping plate.

[0007] Further preferably, a welding plate is welded to the middle end of the inner side of the U-shaped plate, and the transverse clamping plate is welded to the inner side of the welding plate.

[0008] Further preferably, protective pads are bonded to the inner sides of the transverse clamping plate and the longitudinal clamping plate by PP glue, and the material of the protective pads is sponge.

[0009] Further preferably, a servo motor is provided on the left side of the transmission box, and the output end of the servo motor is fixedly connected to the forward and reverse threaded rods.

[0010] Further preferably, guide grooves are provided on the left and right sides of the transmission box and the top of the processing table, and the top of the connecting plate passes through the guide grooves and extends to the top of the processing table.

[0011] Further preferably, both sides of the bottom of the inner cavity of the transmission box are provided with sliding grooves, the bottom of the threaded sleeve is fixedly connected to a slider, and the bottom of the slider is slidably connected to the sliding groove.

[0012] Further preferably, a grinding mechanism mounting plate is welded to the back side of the top of the processing table, and a plurality of mounting holes are opened on the top of the grinding mechanism mounting plate.

[0013] The embodiment of the present invention has the following advantages due to the adoption of the above technical solution:

[0014] 1. The utility model drives the positive and negative threaded rods to rotate through the output end of the servo motor. The positive and negative threaded rods drive the threaded sleeve to move inward through the action of the thread. The threaded sleeve drives the U-shaped plate to move inward through the connecting plate, and the mold is laterally limited by the transverse clamping plate arranged on the inner side of the U-shaped plate. At the same time, through the arrangement of the electric slide and the electric slide, the longitudinal clamping plate can be driven to move inward. When it contacts the mold, the longitudinal position of the mold is limited, realizing the multi-directional limiting function, improving the limiting effect, and avoiding displacement of the mold during the grinding process.

[0015] 2. The utility model can protect the mold that needs to be limited by setting a protective pad to avoid wear caused by direct contact between the longitudinal clamping plate and the transverse clamping plate and the mold. By setting a guide groove, the moving trajectory of the connecting plate can be limited to avoid displacement during its movement. By setting a slider and a slide groove, the threaded sleeve can be limited, thereby improving its stability during movement.

Both sides of the surface of the electric slide 203 are slidably connected with electric sleeves 204, and the inner side of the electric sleeve 204 is fixedly connected with a connecting rod 205. A longitudinal clamping plate 208 is welded to the inner side of the connecting rod 205, a welding plate 202 is welded to the middle end of the inner side of the U-shaped plate 201, and the transverse clamping plate 207 is welded to the inner side of the welding plate 202.

[0027] The output end of the servo motor 704 drives the forward and reverse threaded rods 702 to rotate, and the forward and reverse threaded rods 702 drive the threaded sleeve 705 to move inward through the action of the thread, and the threaded sleeve 705 drives the U-shaped plate 201 to move inward through the connecting plate 703, and the mold is laterally limited by the transverse clamping plate 207 set on the inner side of the U-shaped plate 201. At the same time, through the setting of the electric slide 203 and the electric slide sleeve 204, the longitudinal clamping plate 208 can be driven to move inward. When it contacts the mold, the longitudinal position of the mold is then limited, realizing the multi-directional limiting effect, improving the limiting effect, and avoiding displacement of the mold during the grinding process.

[0028] Example 2

[0029] In one embodiment, the inner sides of the transverse clamping plate 207 and the longitudinal clamping plate 208 are bonded with protective pads 206 by PP glue, and the material of the protective pads 206 is sponge.

When it contacts the mold, the longitudinal position of the mold is then limited, realizing the multi-directional limiting effect, improving the limiting effect, and avoiding displacement of the mold during the grinding process (the grinding mechanism mounting plate in this application is for installing and placing the grinding components of the mold. Because the grinding mechanism is a conventional existing technology, it is not described here).
