Description

Technical Field

[0001] The utility model relates to the field of mold processing, and more specifically, to a grinding device for the inner wall of a mold. Background Art

[0002] In the mold industry, various molds and tools are used to obtain the required products by injection molding, blow molding, extrusion, die casting or forging, smelting and stamping. Due to the different functions of the parts, the shapes of the parts will also be different. When different shapes need to be die-casted at different positions of a mold workpiece, the mold needs to be polished, which will improve the processing accuracy and work efficiency.

[0003] Chinese patent authorization announcement number: CN211540679U, provides a grinding device for the inner wall of a mold. This patent can clamp the processed mold in two sets of resistance plates by setting a telescopic rod and a first spring. By setting a hose and a nozzle, the debris generated during the grinding process can be brushed. By setting a second connecting plate and a pressure plate, the user can replace the damaged grinding stone.

[0004] In the existing technology, the mold inner wall grinding device directly extends into the mold and then rotates, and can only grind the outer area of the rotation range. The grinding range is small, and it is impossible to grind the recessed groove in the mold, which reduces the functionality and practicality of the grinding device. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide a grinding device for the inner wall of the mold, which can be achieved by arranging a limit frame and an electric push rod in the grinding mechanism. The grinding head is fixed at the lower end of the telescopic rod. The electric push rod can control the swing of the telescopic rod, thereby driving the use angle of the grinding head to change. The use angle of the grinding head can be adjusted accordingly according to the diameter of the inner wall of the mold, thereby improving the grinding efficiency. The inclined grinding head can grind the recessed parts of the inner wall of the mold, effectively improving the functionality and practicality of the grinding device.

[0007] 2. Technical solution

[0008] To solve the above problems, the utility model adopts the following technical solutions.

The polishing head is installed at the lower end of the telescopic rod by a fixed installation method. One end of the telescopic rod away from the polishing head is rotationally connected to the output shaft of the telescopic rod. First, start the electric cylinder to drive the whole polishing component to move downwards, insert the polishing head into the mold, and then start the electric push rod to drive the telescopic rod and the polishing head to swing, so that the polishing head contacts the inner wall of the mold.

[0010] Further, second clamping grooves are respectively formed at the front and rear ends inside the limiting frame. Second clamping blocks are fixedly installed at the front and rear ends on the right side of the output shaft of the electric push rod. The second clamping blocks are clamped inside the second clamping grooves. During use, when the output shaft moves left and right to adjust the use angle of the polishing head, the second clamping blocks at the front and rear ends of the output shaft slide inside the second clamping grooves.

[0011] Further, a limiting sliding groove is arranged in the middle of the upper end of the workbench. A first clamping groove communicating with the limiting sliding groove is arranged at the lower end of the limiting sliding groove. The width of the first clamping groove is smaller than that of the limiting sliding groove. A clamping component is installed inside the limiting sliding groove. During use, the arrangement of the limiting sliding groove and the first clamping groove can help limit the clamping component.

[0012] Further, the clamping component includes a first bearing, a double-threaded screw rod and an electric motor.

The sliders are installed at both outer ends of the double-threaded screw by means of threaded connection, and the sliders are arranged inside the limit sliding grooves. The first clamping block is installed at the lower end of the slider by means of fixed installation. The first clamping block is clamped inside the first clamping groove. The clamping plate is installed at the upper end of the slider by means of fixed connection. When in use, when the double-threaded screw rotates, it can drive the two sliders and the clamping plate to move in and out. By moving the clamping plate inward, the limit of the mold can be realized.

[0014] Furthermore, a mold is installed inside the inner sides of the two clamping plates. A control panel is fixedly installed at the upper right end of the support frame. The control panel is electrically connected to the electric motor, the electric cylinder and the electric push rod. When in use, the staff can touch the control panel to control the operation and use of the electric motor, the electric cylinder and the electric push rod.

[0015] 3. Beneficial Effects

[0016] Compared with the prior art, the advantages of the present utility model are as follows:

[0017] (1) In this solution, by arranging a limit frame and an electric push rod inside the grinding mechanism, the grinding head is fixed at the lower end of the telescopic rod. The electric push rod can control the swing of the telescopic rod, thereby driving the use angle of the grinding head to change. The use angle of the grinding head can be adjusted accordingly according to the diameter of the inner wall of the mold, improving the grinding efficiency. Moreover, the inclined grinding head can grind the concave parts of the inner wall of the mold, effectively improving the functionality and practicality of the grinding device.

[0018] (2) When the output shaft adjusts the use angle of the grinding head by moving left and right, the second clamping blocks at the front and rear ends of the output shaft slide inside the second clamping grooves. Through the setting of the second clamping blocks and the second clamping grooves, the stability of the output shaft and the grinding head can be improved.

[0019] (3) By starting the electric motor, the double-threaded screw can be driven to rotate. When the double-threaded screw rotates, it can drive the two sliders and the clamping plate to move in and out. By moving the clamping plate inward, the limit of the mold can be realized. Moreover, through the setting of the first clamping block and the first clamping groove, the fixation of the clamping plate can be strengthened, and the stability of the clamping plate can be improved.
