The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0027] First embodiment:

[0028] See also Figure 1 to Figure 5 ,in Figure 1 This is a front view of the first embodiment of the utility model. Figure 2 The utility model Figure 1 The cross-sectional view along the AA line. Figure 3 The utility model Figure 2 A partial enlarged view of point B in the middle. Figure 4 The utility model Figure 1 Cross-sectional view of the CC line, Figure 5 The utility model Figure 4 A partial enlarged view of point D in the middle.

[0029] The utility model provides a hole opening mechanism for a mold, comprising a slide rail 101, two support rods 102, a base 103 and an adjusting component, wherein the adjusting component comprises a first screw rod 113, two bearings 114, a plurality of C-shaped blocks 115 and a knob 118. The above-mentioned scheme solves the technical problem that each time the second sliding block 111 is adjusted, the limit rod needs to be pulled upward, and the limit rod and the first baffle will drive the first spring to move upward, thereby gradually reducing the stability between the connecting rod 109 and the square frame 106, thereby causing the connecting rod 109 to fall from the frame 106.

[0030] According to this specific embodiment, the slide rail 101 is provided with a first slider 104, a cylinder 105 is provided below the first slider 104, a box 106 is provided at the output end of the cylinder 105, a first motor 107 is provided in the box 106, a hole drilling rod 108 is provided at the output end of the first motor 107, and the hole drilling rod 108 passes through the box 106, a connecting rod 109 is provided on the outside of the box 106, an adjustment slot 110 is provided in the connecting rod 109, a second slider 111 is provided in the adjustment slot 110, and a second slider 111 is provided below the second slider 111. A positioning piece 112 is provided, the slide rail 101 is fixedly connected to the corresponding support rod 102 and is located between the two support rods 102, and the two support rods 102 are respectively fixedly connected to the base 103 and are located above the base 103. By starting the first motor 107, the hole drilling rod 108 is rotated, and then the cylinder 105 is started to drill a hole on the surface of the mold. After the hole drilling is completed, the hole drilling rod 108 is moved to the next position where a hole needs to be drilled, and the positioning piece 112 is inserted into the newly drilled hole, so that the spacing between each drilled hole can be the same.

[0031] Among them, the second slider 111 has a first thread groove 116, and a plurality of limit blocks 117 are arranged on the outer side of the second slider 111. The screw is rotatably connected to the connecting rod 109 through the two bearings 114, and is located in the adjusting groove 110 and passes through one end of the adjusting groove 110. The second slider 111 is threadedly connected to the first screw 113 and sleeved on the first screw 113. The plurality of C-shaped blocks 115 are respectively fixedly connected to the connecting rod 109 and are located on the upper and lower end surfaces of the connecting rod 109, and the plurality of limit blocks 117 are respectively slidably connected to the corresponding C-shaped blocks 115 and are located in the C-shaped blocks 115. The second slider 111 is threadedly connected through the first screw 113 to achieve an adjustment effect. This method will not reduce the stability between the connecting rod 109 and the frame 106, thereby avoiding the situation where the connecting rod 109 falls off the frame 106. At the same time, this adjustment method can more conveniently adjust the second slider 111.

[0032] Secondly, a plurality of anti-slip protrusions 119 are arranged on the outer side of the knob 118. The knob 118 is fixedly connected to the first screw rod 113 and is located at one end of the first screw rod 113. The first screw rod 113 can be easily rotated by the knob 118, and the anti-slip protrusions 119 can improve the gripping force of the knob 118.

[0033] Again, a scale 120 is provided on the outer side of the C-shaped block 115 , and the scale 120 can be used to adjust the distance between the two holes.

[0034] When the second slider 111 is adjusted using the utility model, the knob 118 is held and turned to rotate the knob 118 under the action of the two bearings 114, and the second slider 111 is horizontally moved under the action of the first thread groove 116, and is adjusted to a suitable value by the scale 120. At this time, the setting of the limit block 117 and the C-shaped block 115 can improve the stability between the second slider 111 and the connecting rod 109. This design effectively improves the adjustment efficiency of the second slider 111, and in this way solves the technical problem that each time the second slider 111 is adjusted, the limit rod needs to be pulled upward, and the limit rod and the first baffle will drive the first spring to move upward, so that the stability between the connecting rod 109 and the frame 106 will gradually decrease, thereby causing the connecting rod 109 to fall off the frame 106.

[0035] The second embodiment is:

[0036] Based on the first embodiment, please refer to Figure 6 to Figure 10 ,in Figure 6 It is a three-dimensional stereogram of the second embodiment of the utility model. Figure 7 It is a front view of the second embodiment of the utility model.

[0039] Among them, a second screw 203 is arranged above the anti-slip pad 201, and a nut 204 is arranged on the outer side of the second screw 203. A second thread groove 205 is provided below the support leg 202. The second screw 203 is threadedly connected to the support leg 202 and is located in the second thread groove 205. The support leg 202 is fixedly connected to the base 103 and is located below the base 103. The arrangement of the nut 204 and the second screw 203 can facilitate the subsequent replacement of the damaged anti-slip pad 201.

[0040] Among them, a fixed block 208 is arranged on the first sliding block 104, and a third thread groove 209 is formed in the fixed block 208.

The arrangement of the third screw rod 206 and the second motor 207 can facilitate the transmission of the first sliding block 104, thereby achieving the function of automatically adjusting the drilling rod 108.

[0041] Among them, an active cavity 213 is provided at the bottom of the second slider 111, and a pulling rod 214 is arranged on the outer side of the positioning rod 212. The diameter of the positioning rod 212 is the same as that of the hole-opening drill rod 108. The spring 210 is supported between the limiting ring 211 and the active cavity 213. The limiting ring 211 is fixedly connected to the positioning rod 212 and is located at one end of the positioning rod 212. The limiting ring 211 is also slidably connected to the second slider 111 and is located in the active cavity 213, and the positioning rod 212 passes through the active cavity 213. The spring 210 can prevent the positioning rod 212 from moving out of the opened hole when the hole-opening drill rod 108 is working, thereby improving the tightness between the positioning rod 212 and the opened hole.

[0042] A hole-opening mechanism of a mold using the present embodiment can be supported by the support assembly, so that the base 103 will not directly contact the ground, thereby facilitating subsequent movement. The arrangement of the nut 204 and the second screw rod 203 can facilitate the subsequent replacement of the damaged anti-slip pad 201. The arrangement of the third screw rod 206 and the second motor 207 can facilitate the transmission of the first slider 104, thereby achieving the function of automatically adjusting the hole-opening drill rod 108. The spring 210 can prevent the hole-opening drill rod 108 from moving out of the opened hole when the hole-opening drill rod 108 is working, thereby improving the tightness between the positioning rod 212 and the opened hole.
