[0034] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0035] like Figures 1 to 4 As shown, the embodiment of the present invention provides a circular hole chamfering device for mold base processing, comprising a machine base 1, a feeding slide 2, a clamping mechanism 3, a lifting mechanism 4, a chamfering mechanism 5 and an intermittent blocking mechanism 6;

[0036] An inclined table 10 is provided at one side end of the machine base 1, and the feeding slide 2 is provided on the inclined table 10. The feeding slide 2 is provided with a chute 20 for conveying mold base accessories, and the height of the inclined table 10 gradually decreases along the conveying direction of the feeding slide 2; the setting of the inclined table 10 can make the mold base accessories automatically slide along the chute 20 through the action of gravity, without the need for an additional power source to push the accessories forward, thereby realizing automatic feeding, reducing dependence on manual intervention, and improving production efficiency.

[0037] The clamping mechanism 3 is arranged on both sides of the feeding slide 2. The clamping mechanism 3 is used to clamp the mold base accessories in the slide 20. The lifting mechanism 4 is arranged on the inclined table 10. The lifting mechanism 4 is connected to the chamfering mechanism 5 to drive the chamfering mechanism 5 to perform lifting and lowering adjustment. The chamfering mechanism 5 is used to chamfer the mold base accessories in the clamping mechanism 3; when the mold base accessories are transported to the position of the clamping mechanism 3 under the action of gravity, the clamping mechanism 3 can stably clamp the mold base accessories to prevent them from shifting during the chamfering process. Then the lifting mechanism 4 can drive the chamfering mechanism 5 to abut against the mold base accessories, prompting the chamfering mechanism 5 to chamfer along the edge of the circular hole of the mold base accessories to eliminate sharp edges and form smooth rounded corners.

[0038] The intermittent material stopping mechanism 6 is arranged at the end of the slide 20, and the intermittent material stopping mechanism 6 includes a lifting rod 61, a positioning seat 62, a swing arm 63 and a material stopping rod 64. The positioning seat 62 is arranged at the side end of the inclined table 10 below the feeding slide 2, and the swing arm 63 is connected to the positioning seat 62 through the pin shaft. The swing arm 63 can swing up and down relative to the positioning seat 62, and one end of the swing arm 63 is connected to the lifting mechanism 4 through the lifting rod 61, and the material stopping rod 64 is arranged at the other end of the swing arm 63. The material stopping rod 64 blocks or releases the mold base accessories on the slide 20 as the swing arm 63 swings. When the chamfering mechanism 5 is in the working state, the lifting mechanism 4 will simultaneously drive the lifting rod 61 to press down, thereby driving the swing arm 63 to swing. At this time, the material blocking rod 64 is in a high position. The high-position material blocking rod 64 can block the mold base accessories on the slide 20 to prevent it from continuing to slide; when the chamfering process of a workpiece is completed, the lifting mechanism 4 can drive the chamfering mechanism 5 to move upward. At this time, the lifting rod 61 also rises at the same time, and drives the material blocking rod 64 to swing to a low position through the swing arm 63. The material blocking rod 64 in the low position is no longer in contact with the mold base accessories on the slide 20, so that the mold base accessories can automatically release the material, reducing the tedious operation of manual material collection and improving production efficiency.

[0039] like Figure 1 and Figure 2 As shown, the present invention further includes a blanking plate 71 and a first collection box 72. The blanking plate 71 is tilted at the bottom of the inclined table 10, and the tilt angle of the blanking plate 71 is equal to the tilt angle of the inclined table 10. The first collection box 72 is located below the bottom of the blanking plate 71 and is used to collect mold base parts that have completed the chamfering process. When the mold base parts are released from the chute 20, they can slide through the blanking plate 71 into the first collection box 72 for unified collection.

[0040] like Figure 2 As shown, the blanking plate 71 is further provided with a plurality of chip removal holes 710, and a second collection box 73 is located below the chip removal holes 710. The second collection box 73 is used to collect metal debris generated during the chamfering process. The chamfering process of the mold base parts generates metal debris, which slides onto the blanking plate 71 under the action of gravity and falls through the chip removal holes 710 into the second collection box 73 for automatic collection, eliminating the need for manual cleaning and improving production efficiency.

[0041] like Figure 1 and Figure 2As shown, a third collection box 74 is further included. The bottoms of the first and second collection boxes 72, 73 are each provided with a plurality of filter holes 700. The third collection box 74 is located below the first and second collection boxes 72, 73 to collect the cooling liquid flowing through the filter holes 700. When some metal chips are scattered on the blanking plate 71 and the inclined table 10, the user can flush the blanking plate 71 with water to cause the metal chips to flow under the impact of the water flow onto the blanking plate 71 and fall into the second collection box 73 through the chip removal holes 710.

[0042] like Figure 3 As shown, the clamping mechanism 3 further includes a first cylinder 31, a first slide rail 32, a first slide 33, and a clamping arm 34.

The clamping arm 34 is provided on the side wall of the first slide 33 near the feed slide 2. The clamping arm 34 is provided with an arc-shaped clamping opening 340, which is used to abut against the side wall of the mold base component. The clamping mechanism 3 drives the first slide 33 to move on the first slide rail 32 through the first cylinder 31, thereby achieving the clamping and release of the mold base component by the clamping arm 34, so that the mold base component can be accurately positioned and firmly clamped during the chamfering process, thereby improving the processing accuracy.

[0043] like Figure 2 As shown, the lifting mechanism 4 further includes a support base 41, a second cylinder 42, and a lifting base 43. The support base 41 is disposed on the inclined table 10, and the second cylinder 42 is disposed on the support base 41, with the movable end of the second cylinder 42 facing upward and connected to the lifting base 43. The chamfering mechanism 5 is disposed on the lifting base 43. The second cylinder 42 can drive the chamfering mechanism 5 to move up and down through the lifting base 43, thereby adjusting the distance between the chamfering mechanism 5 and the mold base component, so that the chamfering mechanism 5 can accurately reach the predetermined position for chamfering processing.

[0044] like Figure 4As shown, the chamfering mechanism 5 further includes a rotary motor 51, a spindle box 52, a rotary spindle 53, and a chamfering cutter head 54. The spindle box 52 is located at the bottom of the lifting base 43, and the rotary spindle 53 is rotatably connected to the spindle box 52. The rotary motor 51 is located on the lifting base 43, and the output shaft of the rotary motor 51 is connected to the top of the rotary spindle 53 via a pulley transmission assembly. The chamfering cutter head 54 is connected to the bottom of the rotary spindle 53 via a locking member. The chamfering cutter head 54 is provided with a plurality of chamfering cutting edges 541 along the circumferential direction. The rotary motor 51 can drive the rotary spindle 53 to rotate at high speed, thereby driving the chamfering cutter head 54 connected to the rotary spindle 53 to chamfer the circular holes on the mold base accessories.

[0045] like Figure 2 and Figure 4 As shown, the lifting mechanism 4 further includes a second slide rail 44 and a second slide seat 45. The second slide rail 44 is vertically arranged on the side wall of the support base 41. The second slide rail 44 is connected to the second slide seat 45 via a second slider. The side wall of the spindle box 52 is connected to the second slide seat 45. The provision of the second slide rail 44 and the second slide seat 45 can improve the lifting and lowering stability of the lifting mechanism 4 and prevent the chamfering cutter head 54 from shifting.
