DETAILED DESCRIPTION

[0024] The following is combined with Figure 1-2 This application is described in further detail.

[0025] The present application embodiment discloses a horizontal milling machine for producing molds. Figure 1 and Figure 2 The horizontal milling machine for producing molds includes a spindle box 1 and a milling cutter 2 rotatably mounted on the spindle box 1. The length direction of the milling cutter 2 is perpendicular to the plane of the spindle box 1. A liquid storage ring 3 is installed on the side of the spindle box 1 close to the milling cutter 2. The cross section of the liquid storage ring 3 is a circular ring. The liquid storage ring 3 is a hollow structure for storing coolant. The milling cutter 2 is located in the liquid storage ring 3 and the milling cutter 2 is located at the center of the liquid storage ring 3. The side wall of the liquid storage ring 3 is connected with a liquid inlet hose 4, which is used to communicate with an external pump body for extracting coolant, so as to facilitate the external coolant to be pumped into the liquid storage ring 3.

[0026] Reference Figure 2, an opening 5 is provided on one side of the liquid storage ring 3 away from the spindle box 1, and the opening 5 is arranged along the circumference of the liquid storage ring 3. A sealing ring 6 for sealing the opening 5 is rotatably arranged inside the liquid storage ring 3, and the sealing ring 6 covers the opening 5. The sealing ring 6 is coaxially arranged with the liquid storage ring 3, and the rotation axis of the sealing ring 6 is parallel to the axial direction of the liquid storage ring 3. The sealing ring 6 abuts against the inner wall of the liquid storage ring 3 on the side close to the opening 5, so that the coolant in the liquid storage ring 3 will not flow out from the opening 5; a plurality of nozzles 7 are fixedly penetrated on the sealing ring 6, and the plurality of nozzles 7 are evenly spaced along the circumference of the sealing ring 6, which helps to improve the cooling and lubrication effect of the milling position. In the embodiment of the present application, three nozzles 7 are provided, and in other embodiments, the number of nozzles 7 can be set according to actual needs. The nozzle 7 is connected to the inside of the liquid storage ring 3, and the nozzle 7 is movably arranged in the opening 5. The end of the nozzle 7 away from the sealing ring 6 is bent and faces the end of the milling cutter 2 away from the spindle box 1, so that the coolant sprayed by the nozzle 7 can be sprayed on the milling position of the milling cutter; a rotating component for driving the sealing ring 6 to rotate is provided on the spindle box 1.

[0027] When in use, the coolant is continuously pumped into the liquid storage ring 3 through the external pump body, and the coolant in the liquid storage ring 3 is sprayed to the milling position of the milling cutter 2 and the mold through multiple nozzles 7. The sealing ring 6 is driven by the rotating component to drive the multiple nozzles 7 to rotate along the milling cutter 2, so that the nozzle 7 moves in the opening 5. The nozzle 7 can spray the coolant along the circumference of the milling position of the milling cutter 2 and the mold, thereby cooling and lubricating the milling position, making the milling cutter 2 less likely to be damaged.

[0028] Reference Figure 2 In order to facilitate driving the sealing ring 6 to rotate, the rotating assembly includes a sealing ring 8 and a driving member 9. A plurality of nozzles 7 are fixedly penetrated on the sealing ring 8. The sealing ring 8 is located outside the liquid storage ring 3. The sealing ring 8 and the sealing ring 6 are coaxially arranged. The sealing ring 8 abuts against a side of the liquid storage ring 3 away from the spindle box 1. The sealing ring 8 covers the opening 5, so that the sealing ring 8 and the sealing ring 6 clamp the side of the liquid storage ring 3 away from the spindle box 1, which can guide the rotation of the sealing ring 6 so that the sealing ring 6 and the sealing ring 8 will not shift, and at the same time, the sealing effect of the opening 5 can be further improved; the driving member 9 is arranged on the spindle box 1, and the driving member 9 is used to drive the sealing ring 8 to rotate.

[0029] Reference Figure 2 In order to facilitate driving the sealing ring 8 to rotate, the driving member 9 includes a driving motor 91, a gear 92 and a gear ring 93. The driving motor 91 is fixedly installed on a side of the spindle box 1 close to the milling cutter 2. The driving motor 91 is located outside the liquid storage ring 3. The gear 92 is coaxially fixedly connected to the output shaft of the driving motor 91. The gear ring 93 is fixedly sleeved on the outer wall of the sealing ring 8. The gear 92 is meshed with the gear ring 93. The number of teeth of the gear 92 is less than the number of teeth of the gear ring 93, which helps to reduce the rotation speed of the gear ring 93 so that the coolant sprayed from the nozzle 7 will not be centrifugal.

[0030] When in use, start the drive motor 91, which drives the gear 92 to rotate, and the gear 92 drives the gear ring 93 to rotate slowly, and the gear ring 93 drives the sealing ring 8 to rotate, so that the sealing ring 8 drives multiple nozzles 7 and the sealing ring 6 to rotate with the milling cutter 2 as the axis, which helps the nozzle 7 to spray along the circumference of the milling position, improves the cooling and lubrication effect, and makes the milling cutter 2 less likely to be damaged.

[0031] Reference Figure 2 , sealing rings 10 are embedded on opposite sides of the inner wall of the liquid storage ring 3. The sealing rings 10 are arranged along the circumference of the liquid storage ring 3. One sealing ring 10 is located on the inner wall of the inner ring of the liquid storage ring 3, and the other sealing ring 10 is located on the inner wall of the outer ring of the liquid storage ring 3. The sealing ring 10 can be a rubber ring, a silicone ring, etc., which are not limited here. The blocking ring 6 is located between the sealing rings 10 on both sides, and the blocking ring 6 is rotatably embedded in the sealing ring 10 and slidably abuts against the sealing ring 10. The setting of the sealing ring 10 further enhances the sealing between the blocking ring 6 and the liquid storage ring 3, so that the coolant in the liquid storage ring 3 is not easy to overflow from the opening 5, and the blocking ring 6 can be positioned at the same time.

[0032] Reference Figure 2 , connecting ears 11 are fixed on opposite sides of the liquid storage ring 3, and a mounting member for fixing the connecting ears 11 and the spindle box 1 is provided on the connecting ears 11, and the mounting member includes a bolt 12 that is rotatably penetrated through the connecting ears 11, and the bolt 12 is a hexagonal bolt 12, which is convenient for rotation operation; a threaded hole (not shown in the figure) that is threadedly matched with the bolt 12 is opened on the spindle box 1. In other embodiments, the bolt 12 can be replaced by a screw, a rivet, etc.

[0033] By rotating the bolt 12 to connect or disconnect the bolt 12 with the threaded hole, the liquid storage ring 3 and the spindle box 1 can be installed or removed, which helps to facilitate the replacement of the milling cutter 2.

[0034] The implementation principle of the embodiment of the present application is as follows: when in use, the coolant is continuously pumped into the liquid storage ring 3 through the liquid inlet hose 4 through the external pump body, and the coolant in the liquid storage ring 3 is sprayed out through multiple nozzles 7 under pressure, and the drive motor 91 is started. The drive motor 91 drives the gear 92 to rotate, and the gear 92 drives the gear ring 93 to rotate slowly, and the gear ring 93 drives the sealing ring 8 to rotate, so that the sealing ring 8 drives multiple nozzles 7 and the sealing ring 6 to rotate with the milling cutter 2 as the axis, and the nozzle 7 can spray along the circumference of the milling position of the milling cutter 2 and the mold, so as to improve the cooling and lubrication effect and make the milling cutter 2 less likely to be damaged.
