[0020] A diversion block 7 with a right trapezoidal longitudinal section is fixedly installed on the upper surface of the body 1, and the bottom end of the inclined surface of the diversion block 7 faces the liquid through-hole 5.

[0021] First, the injection mold to be processed is positioned through the positioning component, 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 downward under the action of its own gravity, fall on the upper surface of the diversion block 7, and then flow downward along the inclined surface of the diversion block 7 to enter the collection box 4 in the chute from the liquid through-hole 5, thereby completing the automatic collection and cleaning of the water, and there is no need for manual labor to spend time cleaning the water on the upper surface of the body 1.

[0022] The milling assembly includes a first threaded rod 8 horizontally and rotatably installed in the installation 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 rotation of the slider 9 is restricted by a restricting component. The restricting component includes a restricting rod 14 fixedly installed on the surface of the slider 9. A restricting groove 15 is horizontally opened on the inner wall of the installation frame 2. One end of the restricting rod 14 is slidably disposed in the restricting groove 15. The milling motor 11 is fixedly installed at the bottom end of the driving shaft of the telescopic cylinder 10. One side of the table body 1 is fixedly installed with a placement plate. The surface of the placement plate is fixedly installed with a driving motor 13. The output shaft of the driving motor 13 is fixedly connected to the first threaded rod 8.

[0023] The output shaft of the driving motor 13 can drive the first threaded rod 8 to rotate, so that the slider 9 threadedly sleeved on the first threaded rod 8 drives the telescopic cylinder 10, the milling motor 11, and the milling cutter 12 to move horizontally. And the telescopic cylinder 10 can drive the milling motor 11 and the milling cutter 12 to move vertically. The milling motor 11 can drive the milling cutter 12 to rotate.

A rectangular opening 21 is opened on the upper surface of the placement plate 16.

The surface of the L-shaped block 18 is in sliding contact with the wall of the rectangular opening 21.

[0025] First, place the injection mold to be processed on the upper surface of the placement plate 16 and place it between the two positioning plates 19. Then rotate the second threaded rod 17 to control the two L-shaped blocks 18 to drive the two positioning plates 19 to move relatively until the mutually approaching surfaces of the two positioning plates 19 tightly abut against both sides of the injection mold respectively, then the pressing and clamping fixation of the injection mold can be completed, which is convenient and fast, and can quickly position injection molds of different sizes.

[0026] A plurality of drainage grooves 22 with an isosceles triangle cross-section are equidistantly and symmetrically opened on the surface of the placement plate 16. A discharge port 23 communicating with the rectangular opening 21 is vertically opened on the groove wall of the drainage groove 22.

[0027] The sprayed water will act on the milling cutter 12 and the positioned injection mold, and part of the water will fall on the surface of the placement plate 16, and then will flow down along the inclined groove wall of the drainage groove 22 and fall from the discharge port 23 to the upper surface of the lower diversion block 7, avoiding water accumulation on the upper surface of the placement plate 16.

[0028] The liquid supply component includes a water pump fixedly installed in the liquid storage tank 6 and a discharge pipe 24 (the water pump is a prior art, and its working principle will not be described in detail here). An installation block is fixedly installed on the housing of the milling motor 11. An installation opening is provided on the surface of the installation block. The discharge pipe 24 is fixedly installed in the installation opening, and the discharge end of the discharge pipe 24 faces the milling cutter 12. The output end of the water pump is fixedly communicated with the discharge pipe 24 through a hose 25.

[0029] When the water pump is started, the water pump will suck the water located in the liquid storage tank 6 and introduce it into the hose 25 at the output end, and spray it out from the discharge pipe 24. The sprayed water will act on the surface of the milling cutter 12 and the injection mold.

[0030] An installation ring 27 is fixedly installed on the lower surface of the limiting rod 14 through an L-shaped connecting rod 26. A vertical rod 28 is fixedly installed vertically inside the installation ring 27. A water groove is vertically provided at the top end of the vertical rod 28. A piston rod 29 is slidably and sealingly inserted into the water groove. The bottom end of the vertical rod 28 is fixedly installed with a water inlet pipe 30. The bottom end of the water inlet pipe 30 extends into the chute, and a filter screen is provided inside the bottom end of the water inlet pipe 30. The side wall of the vertical rod 28 is communicated with the inside of the liquid storage tank 6 through a water outlet pipe 31. Both the water inlet pipe 30 and the water outlet pipe 31 are made of elastic materials. Check valves are provided inside both the water inlet pipe 30 and the water outlet pipe 31. The conduction direction of the check valve inside the water outlet pipe 31 is from the inside of the water groove to the inside of the liquid storage tank 6, and the conduction direction of the check valve inside the water inlet pipe 30 is from the outside to the inside of the water groove. The piston rod 29 is controlled to move vertically back and forth through a transmission assembly. The transmission assembly includes a rotating rod 32 vertically rotatably installed on the lower surface of the limiting rod 14, a sliding plate 33, two sprockets 34, and a chain 35. A reciprocating thread is provided on the surface of the rotating rod 32. The sliding plate 33 is threadedly sleeved on the rotating rod 32, and the lower surface of the sliding plate 33 is fixedly connected to the top end 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. The chain 35 is meshed and wound around the two sprockets 34.

[0031] When the slider 9 moves, at this time, 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, under the driving action of the two sprockets 34 and the chain 35, the rotating rod 32 will rotate. The sliding plate 33 threadedly sleeved on the rotating rod 32 will drive the piston rod 29 to move vertically back and forth. During the vertical movement of the piston rod 29, the volume of the space between its bottom end and the bottom of the water groove will continuously change from small to large and then from large to small. When the volume becomes larger, the pressure decreases, and the water in the collection box 4 will enter the water groove from the water inlet pipe 30. When the volume becomes smaller, the pressure increases, and the water in the water groove 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.

[0032] The filter screen 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.

[0033] A rotating shaft is rotatably installed on the back surface of the table body 1. The rotating shaft is located above the sliding 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.

[0034] In the initial state, the surface of the baffle 36 will be in sliding contact with the surface of the collection box 4 located in the sliding groove under the action of its own gravity, so as to limit the collection box 4 from sliding out of the sliding groove. When it is necessary to control the collection box 4 to slide out of the sliding groove, the rotating shaft can be rotated to control the baffle 36 to rotate until its surface is no longer in contact with the surface of the collection box 4.

[0035] In the present invention, the device makes a systematic design for the milling processing of the injection mold and the collection of the milling fluid: first, the positioning component is used to position the injection mold. After closing the frame door 3, the milling component starts the processing. During the processing, the liquid supply component transports the water in the liquid storage tank 6 to the milling component to play the roles of cooling, flushing waste chips and reducing dust. After being sprayed, the water flows into the liquid through port 5 along the inclined surface of the diversion block 7 under the action of gravity and enters the collection box 4 in the sliding groove, realizing the automatic collection of water and saving the time for manually cleaning the water stains on the surface of the table body 1.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
