Description

Technical Field

[0001] The invention relates to the technical field of tread block casting, and in particular to a tire tread block mold casting device. Background Art

[0002] The tread block is the raised part on the tire surface, which together with the tread groove constitutes the tire pattern and has an important impact on the tire performance. Tread block mold casting is a process used to manufacture mold components with specific patterns or designs. Common casting methods include gravity casting, which relies on the liquid metal's own gravity to fill the mold cavity under the action of gravity to form a casting.

[0003] Related patent 202210916048.1 A single-block casting device for an aluminum alloy tread ring comprises: a steel film, a riser, a base and a runner. A riser is fixedly connected to the top of the steel film. A tread block casting method is introduced. In order to avoid excess part of the riser, during the pouring process, the second ball in the discharge pipe cooperates with the first ball in the riser to open and close / close and open the riser and the discharge pipe respectively to close the steel mold to discharge the aluminum liquid inside the riser. Since the first ball and the second ball are respectively arranged inside the riser and the discharge pipe, the aluminum liquid inevitably contacts the first ball and the second ball during the flow inside the riser and the discharge pipe. The first ball and the second ball expand due to heat, causing the discharge pipe and the riser to expand internally. Long-term use leads to loose blockage of the riser and the discharge pipe, and the resistance to the movement of the balls increases, which affects the discharge of excess aluminum liquid in the riser and the use of the riser.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1

[0034] See also Figure 1 - Fig. 9 As shown, a tire tread block mold casting device includes a base 1 and a mold assembly 2 on the base 1, the mold assembly 2 includes a bracket 24, the bracket 24 is fixed to the upper end of the base 1, the bracket 24 is horizontally slidably connected to a mold body 21, and is used for casting a tread block mold. The specific structure is not shown in the figure. A cover body 22 is detachably provided at the upper end of the mold body 21, and a riser 23 is passed through the center of the cover body 22; molten aluminum liquid is injected from the riser 23, and then flows into the mold body 21 until it is fixed, and the required tread block is cast, and then processed into a qualified tread block. The mold body 21 can be moved and adjusted on the bracket 24 so that the riser 23 can be docked with the casting pouring machine for aluminum liquid injection;

[0035] The cover body 22 is provided with a discharge mechanism 3, which includes a slide groove 35 with an arc structure opened at the upper end of the cover body 22, a slide plate 31 with an arc structure is fixed to the outer wall of the bottom end of the riser 23, and the slide plate 31 is slidably arranged inside the slide groove 35, and a discharge pipe 32 with an arc structure is passed through the bottom end of the riser 23, and the discharge pipe 32 is fixedly connected to the upper end of the slide plate 31, and one end of the discharge pipe 32 is rotatably connected to a vertically arranged rotating pipe 33, and a sealing plate 34 with an arc structure is fixed to the outer surface of the bottom end of the riser 23, and the sealing plate 34 is slidably connected to the other end of the slide groove 35. On one side of the inner wall, a bottom plate 37 is fixed on one side of the mold body 21, and a liquid receiving dish 36 is fixed on the bottom end of the mold body 21. The riser 23 is flush with the upper end of the rotating tube 33; the riser 23, the drain pipe 32, and the rotating tube 33 constitute a communicating vessel. When working, when the aluminum liquid is injected from the riser 23, the aluminum liquid enters the inside of the mold body 21, and a part of the aluminum liquid flows into the drain pipe 32 until the riser 23 and the aluminum liquid level at the upper end of the rotating tube 33 are flush, ensuring that the aluminum liquid inside the mold body 21 is full. When the aluminum liquid is injected, the riser 23 rotates counterclockwise ( Figure 1 The sliding plate 31 is driven to slide out of a part of the slide groove 35, so that the drain pipe 32 and the rotating pipe 33 move together, until the sealing plate 34 is driven to slide to cover the riser hole 8 at the center of the cover body 22, and the bottom end of the riser 23 contacts and blocks the upper surface of the bottom plate 37. At this time, the rotating pipe 33 can be rotated to tilt downward toward the liquid receiving dish 36, and the excess aluminum liquid in the riser 23 flows from the drain pipe 32 into the rotating pipe 33 under the action of gravity. Figure 4 , and then flows into the liquid receiving dish 36 from the lower end of the rotating tube 33 for collection and storage. Since the riser 23 rotates and then discharges the excess aluminum liquid inside, and the slide plate 31 and the sealing plate 34 seal the cover body 22, this prevents air and dust from entering the mold body 21 and affecting the molding quality of the pattern block during the molding process of the aluminum liquid inside the mold body 21. In this way, the riser 23 is directly moved to discharge the excess aluminum liquid inside, and there will be no blockage. The excess aluminum liquid can be directly discharged, so that the riser 23 can be used multiple times to inject aluminum liquid for molding inside the mold body 21;

[0036] A driving assembly 5 for driving the riser 23 to move is installed on the upper end of the cover body 22;

[0037] The driving assembly 5 is equipped with a rocker mechanism 6 for driving the rotating tube 33 to rotate and discharge liquid;

[0038] The base 1 is provided with a cover-removing walking mechanism 4 for moving the mold body 21 and flipping the cover body 22 .

[0039] Embodiment 2

[0040] See also Figure 1 , Figure 2 , Figure 6 In order to realize the movement and adjustment of the mold body 21 and the opening of the cover body 22, the cover removal walking mechanism 4 includes a guide rail 42, and inclined rails 43 are fixed at both ends of the guide rail 42. A flat rail 44 is fixed on one side of the top of the connecting rod 63 inclined rail 43. The two flat rails 44 are fixedly connected to the base 1. The flat rail 44 is slidably connected to a walking box 45. A fixed rod 49 is fixed to the upper end of the walking box 45. A torsion spring shaft 48 is rotatably provided at the upper end of the fixed rod 49. A fixed frame 41 is fixed to the torsion spring shaft 48. The bottom end of the fixed frame 41 is connected to the upper end of the cover body 22. The surface is fixedly connected, and the cover taking walking mechanism 4 also includes a motor 46, which is fixed to the outer wall of the walking box 45. The inner surface of the walking box 45 is rotatably connected with four friction wheels 47, and the friction wheels 47 are rollingly connected with the flat rail 44. The output shaft of the motor 46 is fixedly connected with one of the friction wheels 47. A limit rod 411 is fixed at the bottom end of the fixed frame 41, and a support block 412 is fixed on one side of the fixed rod 49. The bottom end of the limit rod 411 is in contact with the upper surface of the support block 412, and a handle 410 is fixed to the movement of the torsion spring rotating shaft 48;

[0041] By adopting the above technical solution, the motor 46 channel works to drive the friction wheel 47 to rotate, and under the action of the friction wheel 47, it rolls on the guide rail 42 (the friction wheel 47 between the friction wheel 47 and the flat rail 44 is sufficient), driving the travel box 45 to slide along the guide rail 42, thereby driving the fixed rod 49 and the fixed frame 41 to move, driving the cover body 22 and the mold body 21 to move along the bracket 24, and adjusting the position of the riser 23, so that the aluminum liquid casting machine can inject aluminum liquid into the position of the riser 23. When the aluminum liquid is injected, the riser 23 is moved to discharge the excess aluminum liquid from the rotating tube 33, and the aluminum liquid is formed into a pattern block in the mold body 21. At this time, the motor 46 can be driven to work, driving the travel box 45 to move to the inclined rail 43 position, so that The mold body 21 and the cover body 22 move together, and then the travel box 45 continues to move onto the inclined rail 43. At this time, the travel box 45 moves up and rotates, and the torsion spring shaft 48 and the fixed rod 49 rotate relative to each other, driving the cover body 22 to move up until the travel box 45 moves onto the flat rail 44, driving the cover body 22 to move up and separate from the upper end of the mold body 21. The handle 410 can be used to rotate the torsion spring shaft 48 to rotate the fixed frame 41 and the cover body 22 to flip open the mold body 21, so as to facilitate the removal of the pattern blocks. In this way, during the movement of the travel box 45, the mold body 21 can be driven to move and adjust the position of the cover body 22 and the riser 23, and the cover body 22 can also be driven to move away from the mold body 21 for mold opening, which is convenient for use.

[0042] In this embodiment, see Figure 7 In order to realize the movement of the mold body 21 and the traveling box 45 together, the mold body 21 is connected with a connecting assembly 7, which includes a vertical rail 71, which is fixed to the outer wall of the mold body 21, and one side of the vertical rail 71 is vertically slidably connected with a sliding rod 72 of an L-shaped structure, and a horizontally arranged rotating column 73 is fixed to the upper end of the sliding rod 72, and one end of the rotating column 73 is rotatably connected to the fixed rod 49; when the traveling box 45 moves to the inclined rail 43 and rises, it drives the sliding rod 72 to move upward and slide up inside the vertical rail 71, and causes the rotating column 73 and the fixed rod 49 to rotate relative to each other, but the sliding rod 72 is not separated from the vertical rail 71, which makes it possible for the traveling box 45 to move to the inclined rail 43 and then to move to the flat rail 44, and the mold body 21 still moves together on the bracket 24, so that it is convenient for the subsequent cover body 22 to cover the mold body 21 again.

One end of the rotating rod 51 is fixedly connected to the outer wall of the riser 23. When the aluminum liquid inside the mold body 21 is injected, the motor 2 53 can be driven to work, drive the gear 2 54 to rotate, and drive the gear 1 52 to rotate, drive the rotating rod 51 to rotate, and drive the riser 23 and the slide plate 31 to slide inside the slide groove 35 until the bottom end of the riser 23 moves to the upper end of the bottom plate 37 to isolate the excess aluminum liquid inside the riser 23. Then, the rotating rod 51 can be rotated to discharge the aluminum liquid inside the riser 23. The electric efficiency is high, the liquid discharge is smooth, and the safety is high.

The three limiting columns 26 are inserted into the inner wall of the edge of the cover body 22.

[0047] Working principle: The motor 1 46 channel works to drive the friction wheel 47 to rotate, and under the action of the friction wheel 47, it rolls on the guide rail 42, drives the travel box 45 to slide along the guide rail 42, drives the cover body 22 and the mold body 21 to move and walk, and moves the riser 23 to the bottom of the aluminum liquid casting machine for injection.
