Description

Technical Field

[0001] The invention relates to the technical field of tire mold processing, and in particular to a tire mold drilling machine and a use method thereof. Background Art

[0002] Molds used for vulcanization molding of various tires. Tire molds are mainly divided into flexible molds and two-half molds. The former consists of a tread ring, a mold sleeve, and upper and lower side panels. The flexible mold is divided into a cone-guided flexible mold and an inclined plane-guided flexible mold. The latter consists of an upper mold and a lower mold. Existing tire molds are often drilled for easy installation and use.

[0003] Existing tire mold drilling processing mostly adopts a new tire mold drilling machine disclosed in the announcement number CN111922380B, which proposes that the drilling effect is unstable during the drilling process, so an improved drilling machine with a strong structure and stable support is obtained, which can make the equipment have good structural stability, but fails to provide effective limiting measures for the tire mold, and the tire mold is different from the general mold structure, such as the attached Figure 3 The tire mold shown has a main body of a disc structure with a through hole in the center. The traditional two-point clamping structure cannot ensure the stability of the tire mold during the drilling process, which can easily cause the tire mold to shift and misalign, and may even cause the drill to contact the platform used to support the tire mold due to lack of balance support.

[0004] As disclosed in the announcement number CN105397148B, a special CNC automatic drilling machine for tire molds, the guide arm and the guide bearing play a guiding and supporting role during the flipping process, making the flipping smoother. The flipping of the sliding vertical plate brings the processed mold to flip along with it. However, when drilling holes in the tire mold with an annular structure, the hole positions are mostly equidistantly distributed circumferentially. The existing drilling structure represented by it is difficult to make a large-scale position adjustment, so only a plurality of drills can be set in a limited equipment space. This will not only increase the preparation cost, but also cause position interference when placing and limiting the tire mold, and there are many inconveniences in the operation process of frequently moving and adjusting the drill.

[0025] The load-bearing support plate 103 is integrally connected to the rear side of the upper end of the load-bearing bracket 101. The guiding arc groove 104 is horizontally opened at the front side of the upper end of the load-bearing bracket 101, thereby reducing the fixed support structure for installing the load-bearing ring 301 and facilitating the placement and adjustment of the tire mold on the machine body 1.

[0026] Refer to the attached Figure 6 The placing part 2 is arranged on the machine body 1, and the placing part 2 is used to support and fix the tire mold. The placing part 2 includes a lifting placer for vertically supporting the tire mold from bottom to top and a balance limiter for symmetrically clamping the tire mold on the same horizontal plane.

[0027] First of all, the lifting placer includes a load-bearing rotating shaft 201, a steering swing rod 202, a guiding slider 203, a lifting platform 204, a lifting support rod 205, and a double-layer placing table 206: The load-bearing rotating shaft 201 is rotatably installed in the U-shaped bracket 102. A driving motor is fixedly installed on the U-shaped bracket 102, and the load-bearing rotating shaft 201 is driven by the driving motor to deflect horizontally. Under the driving action of the driving motor, the load-bearing rotating shaft 201 performs a reciprocating deflection movement of 120°.

[0028] The steering swing rod 202 is fixedly connected to the load-bearing rotating shaft 201. The middle part of the steering swing rod 202 is connected to the load-bearing rotating shaft 201, so as to synchronously pull two guiding sliders 203 to move towards or away from each other during the deflection process.

[0029] The guiding slider 203 is horizontally slidably installed on the U-shaped bracket 102, and the guiding slider 203 is movably pulled by the steering swing rod 202. A linear horizontal groove for slidably sleeving the guiding slider 203 is horizontally opened at the lower end of the U-shaped bracket 102.

Specifically refer to the attached Figure 6, the double-layer placement table 206 is composed of a hollow wire mesh plate 20601 and a limiting central column 20602. The hollow wire mesh plate 20601 is integrally connected to the lifting support rod 205, and the limiting central column 20602 is concentrically welded to the hollow wire mesh plate 20601. The diameter value of the hollow wire mesh plate 20601 is twice the diameter value of the limiting central column 20602. Place the tire mold on the double-layer placement table 206 so that the limiting central column 20602 is sleeved in the central through hole of the tire mold, and the hollow wire mesh plate 20601 is used to support the tire mold. Driving the double-layer placement table 206 to vertically lift can support the tire mold to lift to a predetermined height position.

[0033] Secondly, the balance limiter includes a guide rod 209, an extension plate 210, a concentric frame 211, a moving slider 212, an extension block 213, a limiting arc opening 214, and a fixed clamping member 215: The guide rod 209 is slidably sleeved in the C-shaped support 102. A vertical cavity for slidably sleeving the guide rod 209 is vertically opened in the C-shaped support 102 to provide guiding and limiting effects on the extension plate 210 that performs vertical lifting.

[0034] The extension plate 210 is integrally connected to the lower end of the guide rod 209.

A driving cylinder with an output end fixedly connected to the concentric frame 211 is fixedly installed on the C-shaped support 102, and the concentric frame 211 is driven by the driving cylinder to vertically lift. By setting the concentric frame 211, it is convenient to set two or four extension plates 210, so as to set two or four moving sliders 212 distributed symmetrically.

[0036] The moving slider 212 is horizontally slidably installed in the load-bearing support 101, and the moving slider 212 is movably pulled by the extension plate 210. The extension block 213 and the fixed clamping member 215 that can symmetrically clamp the tire mold are arranged by using the moving slider 212.

[0037] The extension block 213 is integrally connected to the moving slider 212.

[0038] The limiting arc opening 214 is opened in the extension block 213. The limiting arc opening 214 is concentrically distributed with the double-layer placement table 206 to facilitate the sleeving of the tire mold.

[0039] The fixed clamping member 215 is arranged in the limiting arc opening 214, and the fixed clamping member 215 is used to symmetrically abut against the outer wall of the tire mold. Specifically, refer to the attached Figure 8 and attached Fig. 9 , the fixed clamping member 215 is composed of a C-shaped pipe 21501, a driving piston member 21502, a driven piston member 21503, a receiving arc groove 21504, a locking arc plate 21505, and a fourth connecting rod 21506: The U-shaped pipe 21501 is fixedly installed in the moving slider 212.

The locking arc plate 21505 is pin-mounted in the receiving arc groove 21504. The fourth connecting rod 21506 is pin-connected to the driven piston part 21503 and the locking arc plate 21505. During the process of the moving slider 212 moving towards each other, the driving piston part 21502 is extruded to drive the driven piston part 21503. When the driven piston part 21503 is in the extended state, the locking arc plate 21505 is extruded through the fourth connecting rod 21506, so that the locking arc plate 21505 symmetrically clamps the tire mold in the closed state.

[0040] Refer to the attached drawings of the specification Figure 7 - Attachment Fig. 9 The drilling part 3 is arranged on the machine body 1, and the drilling part 3 is used for vertically drilling the tire mold fixed on the placing part 2 from top to bottom.

[0041] The moving support rod 302 is slidably installed on the load-bearing bracket 101 through the guiding arc groove 104. It should be noted that the number of moving support rods 302 is set to two to four to facilitate the corresponding load-bearing support plate 103 to support the load-bearing ring 301. By movably arranging the moving support rod 302, the space on the machine body 1 can be flexibly adjusted to facilitate the picking and placing of the tire mold.

Under the tension of the strong spring 303, the limiting fixture 304 with a tendency of radial movement fixedly supports the load-bearing ring 301.

[0043] The extended moving block 306 is slidably installed on the load-bearing ring 301 through the guiding rail groove 305.

[0044] The self-locking telescopic rod 307 is slidably sleeved in the lengthened moving block 306 and can horizontally expand and contract along the lengthened moving block 306, so that the drill 309 can drill tire molds of different sizes.

[0045] The self-locking lifting rod 308 is slidably mounted on the self-locking telescopic rod 307 to facilitate adjusting the height position of the drill 309, thereby flexibly adjusting the drilling depth.

[0049] Third, a third connecting rod 216 is pin-connected between the extension plate 210 and the moving slider 212.

[0050] The working principle of a tire mold drilling machine can be illustrated by the following operating steps: First, horizontally place the tire mold on the double-layer placing table 206, so that the limiting central column 20602 is sleeved in the central through hole of the tire mold. Control the operation of the lifting placer, so that the load-bearing rotating shaft 201 drives the steering swing rod 202 to deflect. The steering swing rod 202 drives the guiding slider 203 to move horizontally through the first connecting rod 207.

Support the double-layer placing table 206 to move vertically upward through the lifting support rod 205 until the tire mold is lifted to a predetermined height position, avoiding direct contact between the tire mold and the load-bearing bracket 101 in the machine body 1. In this way, it can be avoided that the drill 309 drills through the tire mold and contacts the load-bearing bracket 101; Secondly, the balance limiter is controlled to operate, the concentric frame 211 moves upward through the extension plate 210, and the extension plate 210 drives the movable slider 212 to move toward each other in the horizontal direction through the third connecting rod 216, and the tire mold is initially mounted using the limiting arc opening 214 to initially limit the tire mold, and the movable slider 212 drives the mold tube 21501 to move synchronously, and the driving piston member 21502 is used to squeeze the driven piston member 21503, and the driven piston member 21503 squeezes the locking arc plate 21505 through the fourth connecting rod 21506, and the locking arc plate 21505 in the receiving arc groove 21504 deflects toward the limiting arc opening 214 to symmetrically clamp the tire mold, thereby symmetrically clamping and limiting the tire mold on the double-layer placement table 206; Finally, the movable support rod 302 is moved along the guide arc groove 104, and the limit clamp 304 is mounted on the load-bearing ring 301 under the tension of the strong spring 303 to symmetrically support the load-bearing ring 301, and the extended movable block 306 is moved along the guide rail groove 305, and the self-locking telescopic rod 307 on the extended movable block 306 is driven to horizontally extend and retract, and the self-locking lifting rod 308 on the self-locking telescopic rod 307 is driven to vertically lift and lower, so that the drill 309 drills holes in the tire mold, so as to accurately drill holes in the tire mold at multiple angles and positions.
