The side of the fixed enclosure near the adjustment component has a groove structure. The top of the inner wall of the fixed enclosure is fixedly connected to both ends of one end of the telescopic baffle. A protective door is hinged to the front of the fixed enclosure. The interior of the protective door has an opening structure, and a cover plate is hinged to the top of the opening end of the inner wall of the protective door. A dust collection interface is fixedly connected to one end of the side of the fixed enclosure, and the outward-facing end of the dust collection interface is connected to an industrial vacuum cleaner via a flexible hose.

[0009] Optionally, the column includes a connecting block, and a vertical slot frame is fixedly connected to the top of the other end of the connecting block. The side surface of the vertical slot frame is slidably connected to the inside of the adjusting assembly, and a rack and an anti-slip strip are fixedly connected to the front and rear ends of the vertical slot frame, respectively.

[0010] Optionally, the adjustment assembly includes a lifting slide, the inner wall of which is slidably connected to a groove on the side surface of the vertical slot frame. A chassis is fixedly connected to the front end of the lifting slide, a gear seat is fixedly connected to the center of the top of the chassis, a front frame is fixedly connected to the bottom of the chassis, and a cover frame is fixedly connected to the four sides of the top of the chassis. The top of the front frame facing inward is fixedly connected to the bottom of the cover frame facing outward. An adjusting screw is rotatably connected inside the cover frame. One end of the adjusting screw extending into the cover frame is engaged with the side surface of the top of the gear seat. A hand crank is fixedly connected to the end of the adjusting screw extending outward from the cover frame. A threaded rod is threadedly connected to the other side of the lifting slide.

[0011] Optionally, a friction plate is fixedly connected to one end of the threaded rod extending into the lifting slide, and a rotating shaft seat is fixedly connected to one end of the threaded rod extending outside the lifting slide.

[0013] Optionally, the quick-change connector consists of a connector body, a sliding outer sleeve, a locking steel ball, and a return spring. One end of the quick-change connector body is fixedly connected to the other end of the grinding motor. The sliding outer sleeve of the quick-change connector is slidably connected to the side surface of the connector body. The opposite sides of the quick-change connector body and the sliding outer sleeve are movably connected by the locking steel ball and the return spring.

[0014] This invention provides a grinding fixture for mold manufacturing, which has the following advantages: This grinding fixture for mold production and processing uses a rack and pinion transmission mechanism, which improves the lifting speed compared to the traditional lead screw structure. It can quickly adjust the grinding height to adapt to mold workpieces of different thicknesses. The rack can lift and lower quickly. The fixed surrounding plates, together with the top telescopic baffle and the front protective door, form a closed grinding space, solving the dust pollution problem. The quick-change connector allows for the replacement of the grinding head, and the flip-up baffle ensures protection and provides ample operating space, greatly improving grinding efficiency.

[0015] This grinding fixture for mold production and processing rotates a threaded rod by turning an eccentric wheel rod, causing a friction plate to press against the anti-slip strip on the column, thus achieving rapid locking of the lifting slide. The eccentric wheel structure has a self-locking effect, and the locking force increases with the increase of grinding vibration, completely preventing loosening and slippage. The eccentric friction locking method, where the eccentric wheel rod pushes the friction plate to press against the anti-slip strip on the column, increases the locking force, ensuring that it will not loosen even under strong vibration during grinding, thus guaranteeing stable grinding accuracy.

[0016] This grinding fixture for mold production and processing enables one-click positioning of the mold through a positioning reference block. The T-slot allows for arbitrary adjustment of the pressure plate position. Combined with quick-change pressure plates, it enables rapid clamping of molds of different sizes and shapes. The carbide wear-resistant strip ensures that the reference surface will not wear out during long-term use.

[0017] This grinding fixture for mold production and processing can adjust the height of the enclosed space according to the height of the mold by means of a telescopic baffle. The flip-up baffle can provide an operation entrance without opening the protective door, which ensures the protection effect without affecting the convenience of operation. The dust collection interface sucks all the dust generated by grinding into the vacuum cleaner.

[0018] This grinding fixture for mold production and processing uses a hand crank to rotate an adjusting screw, which in turn drives a gear seat to roll along a rack, enabling the lifting slide to move up and down rapidly. The two rotating shafts can adjust the pitch and rotation angles of the grinding motor, and the telescopic swing arm can adjust the grinding radius, enabling grinding at any angle and position. The locking knob can fix the swing arm in any position to ensure grinding stability. Attached Figure Description
