Description

Technical Field

[0001] This utility model relates to the field of sandblasting equipment, and in particular to a sandblasting equipment for mold surface treatment. Background Technology

[0002] To enhance product aesthetics, various textures are created on automotive interior dashboards and other slush-molded parts. These textures require corresponding designs on the mold. Currently, chemical etching is the most common method. However, chemical etching has the disadvantage of a long etching cycle, making it difficult to meet customer delivery time requirements. To facilitate texture formation on the mold surface, sandblasting has emerged as a method for creating textures. The working principle of sandblasting is to spray steel balls onto the mold surface, thereby forming textures.

[0003] In the prior art, a sandblasting device is disclosed, which includes a collection tank, a sand screening machine, and a sandblasting box. The sand screening machine is used to output steel balls of different types to the sandblasting box. The sandblasting box is connected to a sandblasting head, which is used to perform surface treatment on the mold. The collection tank is used to recover the steel balls and transport them to the sand screening machine. In this structure, the sandblasting head is fixed and the sandblasting position is too limited, making it difficult to fully sandblast the surface of the mold. Moreover, when it is necessary to change the surface, it is necessary to manually adjust it, which affects the sandblasting efficiency of the sandblasting device.

[0004] Therefore, it is necessary to design a new technical solution to solve the above problems. Utility Model Content

The controller controls the sand screening machine 12 to selectively deliver steel balls of a set type into the sandblasting box 13. The heating device 132 and stirring device 133 in the sandblasting box 13 stir and heat the incoming steel balls, making the steel balls more fully heated. Then, the compressed gas output device 14 sprays the steel balls out from the sandblasting head 131.

[0049] See Figure 1 and Figure 2 As shown, a Z-axis drive mechanism 20 is provided on the side of the cabinet 10. The Z-axis drive mechanism 20 includes a Z-axis moving plate 21 and a Z-axis drive device 22 that drives the Z-axis moving plate 21 to move along the Z-axis. The sandblasting box 13 and the compressed gas output device 14 are both provided on the Z-axis moving plate 21. The Z-axis drive device 22 can drive the sandblasting head 131 to move along the Z-axis through the Z-axis moving plate 21.

[0050] Specifically, the Z-axis drive device 22 includes a first motor 221 and a Z-axis lead screw 222 connected to the first motor 221. The Z-axis moving plate 21 is connected to the Z-axis lead screw 222 via a nut. A motor mounting plate 23 is provided on the top of the cabinet 10. The motor mounting plate 23 is located on the side of the sand screening machine 12. The first motor 221 is mounted on the motor mounting plate 23. A vertical slide rail (not shown in the figure) is correspondingly provided on the side of the cabinet 10. The Z-axis moving plate 21 is slidably connected to the vertical slide rail via a slider, making the movement of the Z-axis moving plate 21 more precise. The first motor 221 is electrically connected to the controller.

[0051] The cabinet 10 is provided with a rotating placement platform 30 for placing molds. The rotating placement platform 30 includes a mounting frame 31 and a placement plate 32 that is rotatably mounted on the top of the mounting frame 31. The mounting frame 31 is provided with a rotation drive device 33. The bottom of the placement plate 32 is connected to the rotation drive device 33. The rotation drive device 33 can drive the placement plate 32 to rotate.

[0052] See Figure 1 and Figure 3 As shown, specifically, the mounting frame 31 includes a top plate 311, a peripheral side plate 312 connected to the bottom of the top plate 311, and a plurality of support rods 313 connected to the bottom of the top plate 311. The top plate 311 is mounted above the collection trough 11 via the support rods 313. Some of the support rods 313 are mounted on the guide slope 111. The placement plate 32 is rotatably mounted above the top plate 311. The rotary drive device 33 includes a second motor 331 and a Z-axis rotating shaft 332.

The top of the placement plate 32 is recessed to provide a placement groove 321 for placing the mold. The bottom wall of the placement groove 321 is provided with screws that connect to the top of the Z-axis rotating shaft 332. The peripheral side plate 312 can protect the second motor 331 and prevent it from contacting the ejected steel balls. The diameter of the second bevel gear 334 is smaller than the diameter of the first bevel gear 333, so that the placement plate 32 can rotate slowly, thereby allowing the mold surface to be sprayed with steel balls more fully. The second motor 331 is electrically connected to the controller.

[0053] In this embodiment, a control valve connected to the controller is installed on each delivery pipe to control the operation of the sandblasting equipment.

[0054] The key design feature of this utility model is:

[0055] Its main feature is that a Z-axis drive mechanism is set on the side of the cabinet. The Z-axis drive device of the Z-axis drive mechanism can drive the sandblasting head to move along the Z-axis through the Z-axis moving plate. In conjunction with a rotating placement table, the placement plate of the rotating placement table can rotate. After the mold is placed on the placement plate, the mold surface can be treated more comprehensively through its own rotation combined with the movement of the sandblasting head. The ingenious structural design helps to improve the sandblasting efficiency of the sandblasting equipment.

[0056] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model.
