[0036] First, the injection mold to be processed is positioned by the positioning component, and then the two frame doors 3 are closed, and then the injection mold is milled by the milling component. In this process, the water in the liquid storage tank 6 is supplied to the milling component through the liquid supply component to achieve the effects of cooling, flushing waste chips and reducing dust. The sprayed water will flow down under the action of its own gravity and fall on the upper surface of the guide block 7, and then flow down along the inclined surface of the guide block 7 to the liquid port 5 and into the collection box 4 located in the chute, thereby completing the automatic collection and cleaning of water, and there is no need to spend time manually cleaning the water on the upper surface of the platform 1.

[0037] The milling assembly includes a first threaded rod 8 horizontally rotatably installed in the mounting frame 2, a slider 9 threadedly sleeved on the first threaded rod 8, a telescopic cylinder 10 fixedly installed at the bottom end of the slider 9, a milling motor 11 and a milling cutter 12 fixedly installed on the output shaft of the milling motor 11. The slider 9 is restricted in rotation by a limiting component. The limiting component includes a limiting rod 14 fixedly mounted on the surface of the slider 9. A limiting groove 15 is horizontally opened on the inner wall of the mounting frame 2. One end of the limiting rod 14 is slidably arranged in the limiting groove 15. The milling motor 11 is fixedly mounted on the bottom end of the drive shaft of the telescopic cylinder 10. A mounting plate is fixedly mounted on one side of the table body 1. A drive motor 13 is fixedly mounted on the surface of the mounting plate. The output shaft of the drive motor 13 is fixedly connected to the first threaded rod 8.

[0038] The output shaft of the drive motor 13 can rotate the first threaded rod 8, so that the slider 9 threadedly connected to the first threaded rod 8 moves laterally with the telescopic cylinder 10, the milling motor 11 and the milling cutter 12, and the telescopic cylinder 10 can move vertically with the milling motor 11 and the milling cutter 12, and the milling motor 11 can rotate with the milling cutter 12.

The second threaded rod 17 is horizontally rotatably mounted in the rectangular opening 21, and both ends of the second threaded rod 17 pass through the placement plate 16. The surface of the L-shaped block 18 is in sliding contact with the wall of the rectangular opening 21.

[0040] First, place the injection mold to be processed on the upper surface of the placement plate 16 and between the two positioning plates 19. Then rotate the second threaded rod 17 to control the two L-shaped blocks 18 to move the two positioning plates 19 relative to each other until the two positioning plates 19 are tightly pressed against the two sides of the injection mold. The pressing, clamping and fixing of the injection mold can be completed. It is convenient and quick, and injection molds of different sizes can be quickly positioned.

[0041] A plurality of drainage grooves 22 with isosceles triangle longitudinal sections are symmetrically and equidistantly formed on the surface of the placement plate 16 . A discharge port 23 communicating with the rectangular opening 21 is vertically formed on the groove wall of the drainage groove 22 .

[0042] The sprayed water will act on the milling cutter 12 and the positioned injection mold, and some of the water will fall on the surface of the placement plate 16, and then flow down along the inclined groove wall of the drainage groove 22 to the upper surface of the guide block 7 below that falls from the discharge port 23, preventing water from accumulating on the upper surface of the placement plate 16.

[0043] The liquid supply component includes a water pump and a discharge pipe 24 fixedly installed in the liquid storage tank 6 (the water pump is a prior art and its working principle is not described in detail here). The housing of the milling motor 11 is fixedly installed with a mounting block, and a mounting port is provided on the surface of the mounting block. The discharge pipe 24 is fixedly installed in the mounting port, and the discharge end of the discharge pipe 24 faces the milling cutter 12. The output end of the water pump is fixedly connected to the discharge pipe 24 through a hose 25.

[0044] When the water pump is started, the water in the liquid storage tank 6 is sucked out and passed into the hose 25 at the output end, and then sprayed out from the discharge pipe 24. The sprayed water acts on the surface of the milling cutter 12 and the injection mold.

[0045] The lower surface of the limiting rod 14 is fixedly installed with a mounting ring 27 through an L-shaped connecting rod 26, and a vertical rod 28 is vertically fixedly installed in the mounting ring 27. A water trough is vertically opened at the top of the vertical rod 28, and a piston rod 29 is inserted into the water trough for sliding sealing. A water inlet pipe 30 is fixedly installed at the bottom end of the vertical rod 28, and the bottom end of the water inlet pipe 30 extends into the chute, and a filter is provided in the bottom end of the water inlet pipe 30. The side wall of the vertical rod 28 is connected to the liquid storage tank 6 through the outlet pipe 31. The outlet pipe 31 and the water inlet pipe 30 are both made of elastic material. A one-way valve is provided in the water inlet pipe 30 and the water outlet pipe 31. The conduction direction of the one-way valve in the water outlet pipe 31 is The direction is from the water tank to the liquid storage tank 6, and the conduction direction of the one-way valve in the water inlet pipe 30 is from the outside to the water tank. The piston rod 29 controls the vertical reciprocating movement through the transmission assembly. The transmission assembly includes a rotating rod 32, a slide 33, two sprockets 34 and a chain 35 vertically mounted on the lower surface of the limiting rod 14. A reciprocating thread is provided on the surface of the rotating rod 32, and the slide 33 is threadedly sleeved on the rotating rod 32, and the lower surface of the slide 33 is fixedly connected to the top of the piston rod 29. The two sprockets 34 are respectively fixedly sleeved on the rotating rod 32 and the output shaft of the milling motor 11, and the chain 35 is meshed and wound around the two sprockets 34.

[0046] When the slider 9 moves, the rotating rod 32, the milling motor 11, the vertical rod 28 and the piston rod 29 will all move together. When the output shaft of the milling motor 11 rotates, the rotating rod 32 will rotate under the transmission action of the two sprockets 34 and the chain 35, and the slide plate 33 threadedly connected to the rotating rod 32 will carry the piston rod 29 for vertical reciprocating movement. During the vertical movement of the piston rod 29, the volume of the space between its bottom end and the bottom of the water tank will continue to change from small to large and then from large to small. When the volume increases, the pressure decreases, and the water in the collection box 4 will enter the water tank from the water inlet pipe 30. When the volume decreases, the pressure increases, and the water in the water tank will enter the liquid storage tank 6 from the water outlet pipe 31, thereby realizing the recycling of water and reducing the waste of water resources.

[0047] The filter in the water inlet pipe 30 is used to filter debris to prevent the debris from being sucked into the water tank along with the water.

[0048] A rotating shaft is rotatably mounted on the back of the platform 1 . The rotating shaft is located above the slide groove, and a baffle 36 is fixedly sleeved on the rotating shaft. The surface of the baffle 36 is in sliding contact with the surface of the collection box 4 .

[0049] In the initial state, the surface of the baffle 36 will slide in contact with the surface of the collection box 4 located in the chute under the action of its own gravity, thereby limiting the collection box 4 from sliding out of the chute. When it is necessary to control the collection box 4 to slide out of the chute, the baffle 36 can be controlled to rotate by rotating the shaft until the surface no longer contacts the surface of the collection box 4.

[0050] In the present invention, the device has made a systematic design for the milling processing of injection molds and the collection of milling fluid: first, the positioning component is used to position the injection mold, and after closing the frame door 3, the milling component starts processing. During processing, the liquid supply component transports the water in the liquid storage tank 6 to the milling component to play a role in cooling, flushing waste chips and reducing dust. Under the action of gravity, the sprayed water flows into the liquid port 5 through the inclined surface of the guide block 7 and enters the collection box 4 in the chute, realizing automatic collection of water and saving the time of manually cleaning water stains on the surface of the platform 1.

[0051] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
