Description

Technical Field

[0001] This utility model relates to the field of centrifugal impellers, specifically to a centrifugal impeller forming mold. Background Technology

[0002] Centrifugal impellers are cylindrical and commonly used in gas water heaters, with multiple blades evenly punched out on their cylindrical walls. Currently, centrifugal impellers are manufactured with single blades, meaning the impeller rotates once for each blade punched out, until all blades are punched out.

[0003] Chinese patent discloses a centrifugal impeller forming mold (authorization announcement number CN 107649574 B). This patented technology "uses multiple punches and multiple expansion sleeves to cooperate, and uses a pusher sleeve to simultaneously push multiple punches to punch holes, which can not only reduce processing steps and save costs, but also improve product quality." It solves the problems of "uneven stress on the centrifugal impeller during processing, easy deformation, many processing steps, low production efficiency, and low product qualification rate." However, the patent still has the following problems: the centrifugal impeller in this patent is composed of multiple blades, and the blades are made by stamping. After the processed parts are stamped, they are easily stuck in the lower mold cavity, which makes it inconvenient to remove them. Utility Model Content

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] Please see Figures 1-5 This embodiment provides a centrifugal fan forming mold, including a base 1 and a connecting column 2. The connecting column 2 is installed on the upper end face of the base 1. A connecting sleeve 11 is installed on the outer side wall of the connecting column 2 by sliding fit. Multiple lower mold cavities 12 are installed on the outer side wall of the connecting sleeve 11 along its circumferential direction. A side plate 13 is rotatably installed on the outer end of the lower mold cavity 12 by a pin. An annular seat 14 is arranged on the outer end of the side plate 13. The annular seat 14 is installed on the upper end face of the base 1. A push rod 15 is installed at the top of the connecting sleeve 11. An adjusting cylinder 16 is installed at the bottom of the push rod 15. A fixed seat 17 is installed on the outer side wall of the base 1. An upper cylinder 18 is installed on the upper end face of the fixed seat 17. A disc 19 is installed at the output end of the 18. Multiple lower posts are installed along the circumferential direction at the bottom of the disc 19. An upper pressure plate 21 is installed at the bottom of the lower posts. During operation, the centrifugal impeller is composed of multiple blades, which are made by stamping. The workpiece is placed on the lower mold cavity 12. The upper cylinder 18 is started, which drives the upper pressure plate 21 to move down, thereby stamping the workpiece. The use of multiple lower mold cavities 12 improves the processing efficiency. The regulating cylinder 16 is started, which drives the outer wall of the connecting sleeve 11, so that the side plate 13 moves outward and opens, making it easy to take out the workpiece through the outer end. This avoids the workpiece being stuck in the lower mold cavity 12 after stamping, which would cause jamming and make it inconvenient to take it out.

[0021] The upper end face of the disk 19 is symmetrically equipped with upper posts 22. The upper posts 22 are connected to the bottom of the fixed base 17 by a sliding fit. During operation, the upper post 22 structure is used to ensure the stability of the disk 19 when moving up and down.

[0022] A control panel 23 is installed on the left end face of the fixed base 17. The control panel 23 is electrically connected to the regulating cylinder 16 and the upper cylinder 18. During operation, the control panel 23 contains a PLC program to control the operation of each device.

[0023] The upper surface of the base 1 is provided with multiple upper slots along its circumferential direction. A bottom rod 24 is installed in the upper slot by means of sliding fit. The upper surface of the bottom rod 24 is installed at the bottom of the lower mold cavity 12. During operation, the bottom rod 24 structure is used to ensure the stability of the lower mold cavity 12 when moving up and down.

[0024] The outer side of the annular seat 14 is rotatably mounted on the outer side wall via a pin along its circumferential direction. The top of the outer side seat 25 is connected to the upper surface of the annular seat 14 by a first snap-fit ​​head 26. During operation, the outer side seat 25 presses and fixes the upper end of the side plate 13 to prevent it from sliding up and down, thus ensuring the stability of the stamping. Rotating the outer side seat 25 opens the lower mold cavity 12, thereby controlling the adjusting cylinder 16 to move up and down.

[0025] The upper end face of the connecting sleeve 11 is equipped with a positioning head 27, and the bottom of the disc 19 is provided with a positioning groove that matches it. When the disc 19 moves down during operation, the positioning head 27 is inserted into the positioning groove, thereby positioning and fixing the position of the disc 19 to prevent the disc 19 from shifting position.

[0026] In actual operation, the centrifugal impeller is composed of multiple blades, which are made by stamping. The workpiece is placed on the lower mold cavity 12, and the upper cylinder 18 is started, which drives the upper pressure plate 21 to move down, thereby stamping the workpiece. The use of multiple lower mold cavities 12 improves the processing efficiency. The adjusting cylinder 16 is started, which drives the outer wall of the connecting sleeve 11, so that the side plate 13 moves outward and opens, making it easy to take out the workpiece through the outer end. This avoids the workpiece being stuck in the lower mold cavity 12 after stamping, which would cause jamming and make it inconvenient to take it out.
