Example (b):
as shown in fig. 1 to 3, a thin-wall annular sintered blank shaping mold comprises an upper mold 1 and a lower mold 2. The upper die 1 includes an upper mount 11, an upper punch 12, and an upper guide post 13. The upper punch 12 is fixed to the upper mount 11, and the upper guide post 13 is fixed to the upper punch 12, and the upper punch 12 and the upper guide post 13 are coaxially disposed.
The lower die 2 includes a lower mount 21, an outer reforming sleeve 22, and an inner reforming sleeve 23. The inner reforming sleeve 23 is located inside the outer reforming sleeve 22 and forms the molding cavity 3 with the outer reforming sleeve 22. The inner reforming sleeve 23 forms a receiving groove for the movement of the upper punch 12. The inner reforming sleeve 23 is detachably connected with the lower mounting seat 21.
The lower end of the inner shaping sleeve 23 is used for being rotatably connected to the lower mounting seat 21, a sliding block 41 is fixed at the lower end of the inner shaping sleeve 23, and a placing ring groove 42 for placing the sliding block 41 is formed in the lower mounting seat 21. The inner shaping sleeve 23 is moved from top to bottom, the sliding block 41 is placed in the placing ring groove 42, then the inner shaping sleeve 23 is rotated, the inner shaping sleeve 23 is positioned, and the inner shaping sleeve 23 is not easy to be separated from the lower mounting seat 21.
The outer reforming sleeve 22 is formed by splicing two opposing arcuate reforming rings 221. The lower mounting seat 21 is provided with a sliding groove 211, and an arc-shaped integral ring 221 is slidably connected in the sliding groove 211. The cross section of the sliding groove 211 is arranged in a T shape. A swash plate 5 for driving the arc-shaped shaping rings 221 to approach each other is fixed to the upper mount 11.
The side wall of the arc-shaped integral ring 221 is provided with placing grooves 6, an elastic member 61 is arranged between adjacent placing grooves 6, and the elastic member 61 is a spring and always applies elastic force to the inner wall of the placing groove 6.
One end of the arc-shaped integral ring 221 close to the upper mounting seat 11 is rotatably connected with a contact wheel 51, and the contact wheel 51 is used for contacting with the inclined plate 5.
The inclined plate 5 is provided with a straight groove 71. A spring plate 72 is provided in the straight groove 71, and a pressing plate 73 for abutting against the outer wall of the arc-shaped shaping ring 221 is connected to the spring plate 72.
In summary, when the device is used, a product to be processed is placed in the forming cavity 3, the upper mounting seat 11 moves downward, the contact wheel 51 on the inclined plate 5 is abutted against the outer wall of the arc-shaped shaping ring 221, and the contact wheel 51 applies pressure to the arc-shaped shaping ring 221 while rolling along the outer wall of the arc-shaped shaping ring 221, so that the two arc-shaped shaping rings 221 move towards the direction close to each other until abutting against each other. As the upper mounting seat 11 moves further, the arc-shaped shaping ring 221 abuts against the pressure plate 73, and the pressure plate 73 applies pressure to the arc-shaped shaping ring 221 all the time by the elastic force of the elastic sheet 72, so that the two arc-shaped shaping rings 221 are kept abutting. As the upper mount 11 is further moved down, the upper punch 12 is caused to press the product to be processed and is molded in the molding cavity 3. The upper mounting block 11 is then moved upwards to separate the upper punch 12 from the product. The two arc-shaped shaping rings 221 are pushed away from each other by the elastic force of the elastic member 61, so that the arc-shaped shaping rings 221 are separated from the product. The inner shaping sleeve 23 is rotated, the sliding block 41 is moved to the opening of the placing ring groove 42, and then the inner shaping sleeve 23 is separated from the lower mounting seat 21. Therefore, the product can be taken out smoothly and quickly, and the production efficiency is effectively improved.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
