Description

Technical Field

[0001] This invention relates to the field of tire mold processing technology, and in particular to a tire mold drilling machine and its usage method. Background Technology

[0002] Molds used for vulcanizing and molding various types of tires. Tire molds are mainly divided into movable molds and two-piece molds. The former consists of a tread ring, a mold sleeve, and upper and lower side plates. Movable molds are further divided into conical guide movable molds and inclined plane guide movable molds. The latter consists of an upper mold and a lower mold. To facilitate installation and use, existing tire molds are often drilled.

[0003] Existing tire mold drilling processes often employ a novel tire mold drilling machine disclosed in CN111922380B. This machine addresses the instability of drilling results during the drilling process by developing a robust and stable drilling machine with good structural stability. However, it fails to provide effective limiting measures for tire molds. Furthermore, tire molds differ from general mold structures, as shown in the attached diagram. Figure 3 The tire mold shown has a disc structure as its main body and a through hole in the center. The traditional two-point clamping structure cannot guarantee the stability of the tire mold during the drilling process, which can easily cause the tire mold to shift or become misaligned. In fact, the lack of balanced support may even cause the drill to come into contact with the platform used to support the tire mold.

[0004] For example, the CNC automatic drilling machine for tire molds disclosed in CN105397148B uses guide arms and guide bearings to provide guidance and support during the flipping process, making the flipping smoother. The flipping of the sliding plate also flips the mold being processed. However, when drilling tire molds with annular structures, the holes are mostly distributed circumferentially. Existing drilling structures, represented by this type, are difficult to adjust significantly. Therefore, multiple drills can only be set in the limited equipment space. This not only increases the manufacturing cost but also causes positional interference when placing and limiting the tire mold. It also causes many inconveniences in the process of frequently moving and adjusting the drills. Summary of the Invention

[0005] This invention provides a reverse welding test to solve the defect in the prior art where it is difficult to fix the tire mold, which affects the drilling process.

[0006] On one hand, the present invention provides a tire mold drilling machine, including a machine body, and further including:

[0007] The placement part is disposed on the machine body and is used to support and fix the tire mold.

[0022] On the other hand, a first connecting rod is pinned between the end of the steering lever and the guide slider, and a second connecting rod is pinned between the guide slider and the lifting platform;

[0023] The double-layer placement platform consists of a hollow mesh plate and a limiting center column. The hollow mesh plate is integrally connected to the lifting support rod, and the limiting center column is concentrically welded to the hollow mesh plate. The diameter of the hollow mesh plate is twice the diameter of the limiting center column.

[0024] On the other hand, the balance limiter includes:

[0025] A guide rod, which is slidably fitted into the C-shaped bracket;

[0026] An extension plate, which is integrally connected to the lower end of the guide rod;

[0027] A concentric frame, which is fixedly connected to the extension plate, is driven to move vertically up and down by a drive cylinder;

[0028] A movable slider is horizontally slidably installed in the load-bearing bracket, and the movable slider is movably pulled by the extension plate;

[0029] An extension block, which is integrally connected to the movable slider;

[0030] A limiting arc opening is formed in the extension block;

[0031] A fixing clip is disposed in the limiting arc opening, and the fixing clip is used to symmetrically abut against the outer wall of the tire mold.

[0032] On the other hand, a third link is connected between the extension plate and the movable slider by a pin.

[0033] The fixing clip consists of an I-shaped tube, a driving piston, a driven piston, a receiving arc groove, a locking arc plate, and a fourth connecting rod.

[0035] On the other hand, the drilled portion includes:

[0036] A load-bearing ring, which is fixedly installed on the load-bearing support plate;

[0037] A movable support rod, which is slidably mounted on the load-bearing bracket via the guide arc groove;

[0038] A high-strength spring, which is fixedly installed on the movable support rod;

[0039] A limiting clamp is fixedly connected to the powerful spring and is slidably fitted into the movable support rod. The limiting clamp is used to symmetrically support the load-bearing ring.

[0040] Guide rail groove, the guide rail groove being formed in the load-bearing ring;

[0041] An extended movable block is slidably mounted on the load-bearing ring via the guide rail groove;

[0042] The self-locking telescopic rod is slidably fitted into the extended movable block;

[0044] A drill bit, which is fixedly installed on the self-locking lifting rod.

[0045] On the other hand, the limiting clamp has a Y-shaped structure.

[0046] The above-mentioned method of using a tire mold drilling machine includes the following steps:

[0047] Step S1: Place the tire mold horizontally on the double-layer placement platform, so that the limiting center column is fitted into the center through hole of the tire mold. Control the operation of the lifting placement device, so that the load-bearing rotating shaft drives the steering rocker to deflect. The steering rocker drives the guide slider to move horizontally through the first connecting rod. The guide slider supports the lifting platform to move vertically upward through the second connecting rod. The lifting support rod supports the double-layer placement platform to move vertically upward until the tire mold is raised to the predetermined height position.

[0048] Step S2: Control the operation of the balance limiter. The concentric frame moves upward through the extension plate. The extension plate drives the moving slider to move towards each other in the horizontal direction through the third connecting rod. The tire mold is initially fitted using the limiting arc opening. The moving slider drives the C-shaped tube to move synchronously. The driving piston squeezes the driven piston. The driven piston squeezes the locking arc plate through the fourth connecting rod. The locking arc plate in the receiving arc groove deflects into the limiting arc opening to symmetrically clamp the tire mold.

[0049] Step S3: Move the movable support rod along the guide arc groove, and under the tension of the strong spring, make the limiting clamp fit on the load-bearing ring to provide symmetrical support for the load-bearing ring. Move the extended moving block along the guide rail groove, drive the self-locking telescopic rod to extend and retract horizontally on the extended moving block, and drive the self-locking lifting rod to lift and retract vertically on the self-locking telescopic rod, so that the drill drills holes in the tire mold.

[0050] This invention provides a tire mold drilling machine and its usage method. By concentrically mounting the tire mold and adjusting its height, while simultaneously clamping and limiting the tire mold symmetrically, a drill is driven at the top of the tire mold to adjust its circumferential position, facilitating multi-point drilling operations on the tire mold at multiple locations. Specifically:

[0051] By using a load-bearing bracket and a U-shaped bracket to set up a steering rocker driven by a drive motor, the guide slider and the lifting platform are moved linearly and reciprocally, thereby supporting the vertical lifting of the double-layer placement platform used to place the tire mold, and avoiding direct contact between the tire mold and the machine body during drilling.

[0052] A concentric frame is set up to be vertically lifted and lowered by a drive cylinder, so that a sufficient number of movable sliders can be set as needed. During the radial movement of the movable sliders, the extension blocks are used to initially fit the tire mold. Then, the cooperating drive piston and driven piston are used to squeeze the locking arc plate to symmetrically clamp and limit the tire mold in the limiting arc.

[0053] A load-bearing ring is set up using a load-bearing support plate, and a movable support rod and a limiting clamp are set up using a guide arc groove to symmetrically support the load-bearing ring, so as to ensure the balance and support of the load-bearing ring. The load-bearing ring provides circumferential support for the drill, enabling the drill to perform drilling operations on the tire mold at multiple angle positions. Attached Figure Description

[0076] like Figure 1 As shown, a tire mold drilling machine includes a machine body 1, a placement part 2 and a drilling part 3. The tire mold is placed on the machine body 1 through the placement part 2, the height of the tire mold is adjusted and then the position is fixed, and the tire mold is drilled at multiple points through the drilling part 3.

[0077] It is worth noting that: the body 1 includes a load-bearing bracket 101, a U-shaped bracket 102, a load-bearing support plate 103, and a guide arc groove 104. It should be noted that:

[0078] The load-bearing support 101 is a platform structure supported by four legs, and a through hole is provided at the center of the load-bearing support 101. The through hole is used to set up a movable support lifting device so that the tire mold can be placed on the vertical line of the corresponding body 1.

[0079] The U-shaped bracket 102 is integrally connected to the lower end of the load-bearing bracket 101. The U-shaped bracket 102 has an upward opening and can be equipped with a lifting and placing device with a symmetrical structure on both sides.

[0080] The load-bearing support plate 103 is integrally connected to the upper rear side of the load-bearing bracket 101, and the guide arc groove 104 is horizontally opened at the upper front side of the load-bearing bracket 101, thereby reducing the fixed support structure used to install the load-bearing ring 301 and facilitating the placement and adjustment of the tire mold on the machine body 1.

[0081] Refer to the instruction manual appendix Figure 6The placement part 2 is disposed on the body 1 and is used to support and fix the tire mold. The placement part 2 includes a lifting placement device 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.

[0082] First, the lifting and placing device includes a load-bearing rotating shaft 201, a steering rocker arm 202, a guide slider 203, a lifting platform 204, a lifting support rod 205, and a double-layer placing platform 206.

[0083] The load-bearing rotating shaft 201 is rotatably mounted in the U-shaped bracket 102. A drive motor is fixedly mounted on the U-shaped bracket 102, and the load-bearing rotating shaft 201 is driven by the drive motor to deflect horizontally. Under the driving action of the drive motor, the load-bearing rotating shaft 201 performs a 120° reciprocating deflection motion.

[0084] The steering rocker arm 202 is fixedly connected to the load-bearing rotating shaft 201. The middle part of the steering rocker arm 202 is connected to the load-bearing rotating shaft 201 so as to synchronously pull the two guide sliders 203 to move in opposite directions during the deflection process.

[0085] The guide slider 203 is horizontally slidably mounted on the U-shaped bracket 102, and the guide slider 203 is movably pulled by the steering rocker 202. The lower end of the U-shaped bracket 102 is horizontally provided with a straight horizontal groove for sliding the guide slider 203.

[0086] The lifting platform 204 is vertically slidably installed on the U-shaped bracket 102, and the lifting platform 204 is movably pulled by the guide slider 203. The U-shaped bracket 102 has vertical slots on both sides for sliding the lifting platform 204.

[0087] The lifting support rod 205 slides through the load-bearing bracket 101, and the lifting support rod 205 is fixedly connected to the lifting platform 204. Under the support of the lifting platform 204, the lifting support rod 205 slides through the through hole in the middle of the machine body 1.

[0088] The double-layer placement platform 206 is integrally connected to the top of the lifting support rod 205, which passes through the load-bearing bracket 101. The double-layer placement platform 206 is used to mount and support the tire mold. Please refer to the attached instruction manual for details. Figure 6 The double-layer placement platform 206 consists of a hollow mesh tray 20601 and a limiting center column 20602. The hollow mesh tray 20601 is integrally connected to the lifting support rod 205, and the limiting center column 20602 is concentrically welded to the hollow mesh tray 20601. The diameter of the hollow mesh tray 20601 is twice the diameter of the limiting center column 20602. A tire mold is placed on the double-layer placement platform 206, so that the limiting center column 20602 is fitted into the central through hole of the tire mold. The hollow mesh tray 20601 is used to support the tire mold. Driving the double-layer placement platform 206 to lift vertically can support the tire mold to lift to a predetermined height position.

[0089] Secondly, the balance limiter includes a guide rod 209, an extension plate 210, a concentric frame 211, a movable slider 212, an extension block 213, a limiting arc 214, and a fixing clip 215.

[0090] The guide rod 209 is slidably fitted into the U-shaped bracket 102. The U-shaped bracket 102 has a vertical cavity for slidingly fitting the guide rod 209, so as to provide guidance and limiting function for the extension plate 210 that is vertically raised and lowered.

[0091] The extension plate 210 is integrally connected to the lower end of the guide rod 209.

[0092] The concentric frame 211 is fixedly connected to the extension plate 210. The output end of the drive cylinder is fixedly installed on the bracket 102 and is fixedly connected to the concentric frame 211. The concentric frame 211 is driven to rise and fall vertically by the drive cylinder. By setting the concentric frame 211, two or four extension plates 210 can be set, thereby setting two or four symmetrically distributed sliding blocks 212.

[0093] The movable slider 212 is horizontally slidably installed in the load-bearing bracket 101, and the movable slider 212 is movably pulled by the extension plate 210. The movable slider 212 is used to set the extension block 213 and the fixing clip 215 that can symmetrically clamp the tire mold.

[0094] The extension block 213 is integrally connected to the movable slider 212.

[0095] 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 platform 206 to facilitate the assembly of the tire mold.

[0096] The fixing clip 215 is disposed in the limiting arc opening 214, and the fixing clip 215 is used to symmetrically abut against the outer wall of the tire mold. Please refer to the attached instruction manual for details. Figure 8 With appendix Figure 9 The fixing clip 215 is composed of an inverted tube 21501, a driving piston 21502, a driven piston 21503, a receiving arc groove 21504, a locking arc plate 21505, and a fourth connecting rod 21506.

[0097] The C-shaped tube 21501 is fixedly installed in the movable slider 212, the driving piston 21502 is fixedly installed on the movable slider 212, and the driving piston 21502 is slidably fitted into the lower opening of the C-shaped tube 21501. The driven piston 21503 is slidably fitted into the upper opening of the C-shaped tube 21501. The receiving arc groove 21504 is opened in the limiting arc opening 214, and the locking arc plate 21505 is pin-mounted in the receiving arc groove 21504. In the middle, the fourth connecting rod 21506 is pin-connected to the driven piston 21503 and the locking arc plate 21505. During the process of moving the slider 212 towards each other, it squeezes the driving piston 21502 to drive the driven piston 21503. When the driven piston 21503 is in the extended state, it squeezes the locking arc plate 21505 through the fourth connecting rod 21506, so that the locking arc plate 21505 symmetrically clamps the tire mold in the closed state.

[0098] Refer to the instruction manual appendix Figure 7 -Appendix Figure 9 The drilling section 3 is provided on the machine body 1, and the drilling section 3 is used to drill vertical holes from top to bottom into the tire mold fixed on the placement section 2. The drilling section 3 includes a load-bearing ring 301, a movable support rod 302, a strong spring 303, a limiting clamp 304, a guide rail groove 305, an extended movable block 306, a self-locking telescopic rod 307, a self-locking lifting rod 308, and a drill 309.

[0099] The load-bearing ring 301 is fixedly installed on the load-bearing support plate 103, and the guide rail groove 305 is opened in the load-bearing ring 301. The two are concentrically arranged with the double-layer placement platform 206 to facilitate axial movement around the tire mold.

[0100] The movable support rod 302 is slidably installed on the load-bearing bracket 101 through the guide arc groove 104. It should be noted that the number of movable support rods 302 is set to two to four so that the corresponding load-bearing support plate 103 can support the load-bearing ring 301. By flexibly setting the movable support rods 302, the space on the machine body 1 can be flexibly adjusted so as to pick up and put down the tire mold.

[0101] A strong spring 303 is fixedly installed on the movable support rod 302. The limiting clamp 304 has a Y-shaped structure. The limiting clamp 304 is fixedly connected to the strong spring 303 and is slidably fitted in the movable support rod 302. The limiting clamp 304 is used to symmetrically support the load-bearing ring 301. The strong spring 303 is fitted on the limiting clamp 304. Under the tension of the strong spring 303, the limiting clamp 304, which has a radial movement tendency, fixes and supports the load-bearing ring 301.

[0102] The extended moving block 306 is slidably mounted on the load-bearing ring 301 via the guide rail groove 305.

[0103] The self-locking telescopic rod 307 is slidably fitted into the extended moving block 306, and can move horizontally along the extended moving block 306, so that the drill 309 can perform drilling operations on tire molds of different sizes.

[0104] The self-locking lifting rod 308 is slidably installed on the self-locking telescopic rod 307 to facilitate adjustment of the height position of the drill 309, thereby flexibly adjusting the drilling depth.

[0105] The drill bit 309 is fixedly installed on the self-locking lifting rod 308.

[0106] It should be noted that:

[0107] First, the lifting device and the balance limiter are both set by the load-bearing bracket 101 and the U-shaped bracket 102, and the drilling part 3 is set by the load-bearing support plate 103 and the guide arc groove 104.

[0108] Second, a first connecting rod 207 is pin-connected between the end of the steering lever 202 and the guide slider 203, and a second connecting rod 208 is pin-connected between the guide slider 203 and the lifting platform 204.

[0109] Third, a third connecting rod 216 is pin-connected between the extension plate 210 and the movable slider 212.

[0110] The working principle of a tire mold drilling machine can be explained through the following operating steps:

[0111] First, the tire mold is placed horizontally on the double-layer placement platform 206, so that the limiting center column 20602 is fitted into the center through hole of the tire mold. The lifting placement device is controlled to operate, so that the load-bearing rotating shaft 201 drives the steering rocker arm 202 to deflect. The steering rocker arm 202 drives the guide slider 203 to move horizontally through the first connecting rod 207. The guide slider 203 supports the lifting platform 204 to move vertically upward through the second connecting rod 208. The double-layer placement platform 206 is supported to move vertically upward through the lifting support rod 205 until the tire mold is raised to the predetermined height position, so as to avoid the tire mold from directly contacting the load-bearing bracket 101 in the machine body 1. In this way, the drill 309 can be prevented from drilling through the tire mold and contacting the load-bearing bracket 101.

[0112] Secondly, the operation of the balance limiter is controlled. The concentric frame 211 moves upward through the extension plate 210. The extension plate 210 drives the moving slider 212 to move in opposite directions in the horizontal direction through the third connecting rod 216. The tire mold is initially fitted by the limiting arc 214 to initially limit the tire mold. The moving slider 212 drives the C-shaped tube 21501 to move synchronously. The driving piston 21502 squeezes the driven piston 21503. The driven piston 21503 squeezes the locking arc plate 21505 through the fourth connecting rod 21506. The locking arc plate 21505 in the receiving arc groove 21504 deflects into the limiting arc 214 to symmetrically clamp the tire mold, thereby symmetrically clamping and limiting the tire mold on the double-layer placement platform 206.

[0113] Finally, the moving support rod 302 moves along the guide arc groove 104, and under the tension of the strong spring 303, the limiting clamp 304 is fitted onto the load-bearing ring 301 to provide symmetrical support for the load-bearing ring 301. The extended moving block 306 moves along the guide rail groove 305, and the self-locking telescopic rod 307 is driven to extend and retract horizontally on the extended moving block 306. The self-locking lifting rod 308 is driven to lift and retract vertically on the self-locking telescopic rod 307, 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.

[0114] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
