Description

Technical Field

[0001] The utility model relates to the technical field of bucket tooth manufacturing, in particular to a bucket tooth processing mould. Background Art

[0002] Bucket teeth are similar to human teeth. They are important parts of excavators and loaders. They are consumable parts. They mainly include tooth seats and tooth tips, which are connected as a whole by a pin. Since the main part of the bucket teeth that wears is the tooth tip, when the bucket teeth are worn, only the tooth tip needs to be replaced.

[0003] A Chinese patent (authorization announcement number: CN 214872032 U, authorization announcement date: 2021.11.26) proposes a loader bucket tooth mold, which includes an upper mold, a lower mold and a locking device. The upper mold is aligned with the lower mold, and the upper mold is opened and closed and connected to the lower mold to realize mold opening and mold closing operations. A cavity for forming the loader bucket tooth is provided between the upper mold and the lower mold. The locking device is installed on the upper mold, and the locking device can perform a locking operation between the upper mold and the lower mold. A positioning groove is provided on the upper mold, and a positioning block is provided on the lower mold. The positioning block is clamped in the positioning groove. The locking device includes a locking rod, and a locking groove is provided on the positioning block. The locking rod can extend into the locking groove to fix the positioning block in the positioning groove. Under the action of the locking rod, the locking rod can fix the positioning block in the positioning groove, so that the upper mold and the lower mold can be fixed during the mold closing process, the mold closing accuracy is improved, and it is ensured that there is no offset between the upper mold and the lower mold, and the quality of the product produced by the entire mold is improved.

[0004] The processing of the tooth tip mainly adopts the casting molding process, in which the molten liquid is poured into the mold, and the product is formed after cooling and molding. After that, a through hole for the pin shaft needs to be drilled at the position where the tooth tip and the tooth seat cooperate. Although the above patent can ensure that the upper mold and the lower mold do not offset, it is still necessary to drill a through hole for the pin shaft later, and one-time molding cannot be achieved, which affects work efficiency. For this reason, we propose a mold for bucket tooth processing. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4The utility model provides a technical solution: a bucket tooth processing mold, including a base 1, a mold base 14 is fixedly installed on the upper end surface of the base 1, a mold cavity 10 is opened on the upper end surface of the mold base 14, a mounting frame 4 is bolted to the upper end surface of the base 1, a cylinder 7 is installed on the upper end surface of the mounting frame 4, a mounting plate 8 is fixedly connected to the output end of the cylinder 7, a core block 9 is installed at the bottom of the mounting plate 8, a through hole 6 is opened on the core block 9, a core rod 18 is penetrated on the left and right end surfaces of the mold base 14, a moving component for driving the core rods 18 on the left and right sides to move synchronously is installed on the rear side of the mold base 14, and a rotating component for driving the core rod 18 to rotate is installed on the rear side of the upper end surface of the base 1.

[0024] When in use, the cylinder 7 drives the core block 9 to move downward, and the core block 9 will be molded into the cavity 10 in the mold base 14. The gap between the core block 9 and the cavity 10 forms an injection cavity. Then the moving component drives the core rods 18 on the left and right sides to move relative to each other. The core rod 18 will be inserted into the through hole 6 on the core block 9, and then the molten liquid will be injected into the injection cavity. During the cooling and molding process, the core rod 18 can be driven to rotate by rotating the component as needed. The rotating core rod 18 can prevent the liquid from solidifying on the core rod 18 during the cooling and molding process. After cooling and molding, the moving component is used again to separate the core rod 18 from the cavity 10, and then the cylinder 7 drives the core block 9 to rise and open the mold. The final product will have its own pin shaft hole, thereby avoiding the need for later hole opening, effectively improving production efficiency.

[0025] The moving assembly includes a fixed frame 12, which is fixedly connected to the upper end surface of the base 1, a first motor 3 is fixedly installed on the left end surface of the fixed frame 12, a screw rod 2 is fixedly connected to the output end of the first motor 3, the right end of the screw rod 2 is rotatably connected to the inner right side wall of the fixed frame 12, a strip slide is opened on the upper end surface of the fixed frame 12, and moving blocks 23 are slidably assembled on the left and right sides of the inner side of the strip slide, the screw rod 2 is threadedly penetrated on the moving block 23, the front side surface of the moving block 23 is fixedly connected to the fixed plate 22, and the core rod 18 is rotatably penetrated on the fixed plate 22.

[0026] When the moving assembly is used, the first motor 3 drives the screw rod 2 to rotate, and the screw rod 2 rotates to drive the left and right moving blocks 23 to move relative to or apart from each other, thereby causing the left and right core rods 18 to move relative to or apart from each other.

[0027] The screw rod 2 is a bidirectional screw rod with two sections of threads in opposite directions.

[0028] The rotating assembly includes a second motor 11, and connecting plates are fixedly connected to the left and right sides of the upper end surface of the base 1, and a rotating tube 15 is rotatably installed between the connecting plates on the left and right sides. The second motor 11 is bolted on the connecting plate on the right side, and the output end of the second motor 11 is fixedly connected to the rotating tube 15. A through sliding opening is opened on the outer surface of the rotating tube 15, and sliders 21 are slidably connected to the left and right sides of the inner side of the through sliding opening. The outer surface of the rotating tube 15 is slidably sleeved with sleeves 20 on the left and right sides, and the outer surface of the sleeve 20 is fixedly sleeved with an active transmission wheel 19, and the end of the core rod 18 is fixedly connected to a driven transmission wheel 16, and a transmission belt 17 is connected between the driven transmission wheel 16 and the active transmission wheel 19, and the rear side of the moving block 23 is fixedly connected to a driving plate 24, and the sleeve 20 is transmitted through the driving plate 24.

[0029] When the moving blocks 23 on the left and right sides move, the sleeve 20 will be pulled to slide along the rotating tube 21 through the driving plate 24. When the core rod 18 needs to be rotated, the second motor 11 is started, and the second motor 11 will drive the rotating tube 15 to rotate. When the rotating tube 15 rotates, the active transmission wheel will be driven to rotate. Since a transmission belt 17 is connected between the driven transmission wheel and the active transmission wheel, the core rods 18 on the front and rear sides rotate synchronously when the second motor 11 is started, which can prevent the liquid from solidifying on the core rod 18 and making it difficult to detach the core rod 18 later.

[0030] A plurality of positioning holes 13 are formed on the upper end surface of the mold base 14 , and a plurality of positioning columns 5 are fixedly connected to the bottom of the mounting plate 8 , and the positioning columns 5 are adapted to the positioning holes 13 .

[0031] When the mold is closed, the positioning column 5 will be inserted into the corresponding positioning hole 13, thereby improving the accuracy of the mold closing.

[0032] The rear side of the mold base 14 is connected with an injection tube communicating with the mold cavity 10 .

[0033] Working principle: When in use, the cylinder 7 drives the core block 9 to move downward, and the core block 9 will be molded into the cavity 10 in the mold base 14. The gap between the core block 9 and the cavity 10 forms an injection cavity. Then the moving assembly drives the core rods 18 on the left and right sides to move relative to each other. The core rod 18 will be inserted into the through hole 6 on the core block 9, and then the molten liquid will be injected into the injection cavity. During the cooling and molding process, the core rod 18 can be driven to rotate by the rotating assembly as needed. The rotating core rod 18 can prevent the liquid from solidifying on the core rod 18 during the cooling and molding process. After cooling and molding, the moving assembly is used again to separate the core rod 18 from the cavity 10. Then the cylinder 7 drives the core block 9 to rise and open the mold. The final product will have its own pin shaft hole, thereby avoiding the need for later hole opening, effectively improving production efficiency.

[0034] When the moving assembly is used, the first motor 3 drives the screw rod 2 to rotate, and the screw rod 2 rotates to drive the moving blocks 23 on the left and right sides to move relative to or apart from each other, thereby causing the core rods 18 on the left and right sides to move relative to or apart from each other;

[0035] When the rotating assembly is used, the second motor 11 is started, and the second motor 11 will drive the rotating tube 15 to rotate. When the rotating tube 15 rotates, it will drive the active transmission wheel to rotate. Since a transmission belt 17 is connected between the driven transmission wheel and the active transmission wheel, the core rods 18 on the front and rear sides rotate synchronously when the second motor 11 is started, which can prevent the liquid from solidifying on the core rod 18 and making it difficult to detach the core rod 18 later. When the moving blocks 23 on the left and right sides move, the sleeve 20 will be pulled to slide along the rotating tube 21 through the driving plate 24, thereby not affecting the movement of the moving assembly.
