[0031] Reference Figure 1-5 A multi-cavity stamping die 100 for automotive clutch transmission plates includes: a base 101, a support column 102, a fixing plate 103, a hydraulic cylinder 104, a punch 105, a lower die 106, a first sliding plate 107, a first spring 108, a limiting block 109, a first slider 110, a driving block 112, a transmission block 113, and a cylinder 114. The support column 102 is fixedly connected to the base plate. The fixing plate 103 is fixedly connected to the support column 102. The fixing plate 103 is located at the upper end of the support column 102. The base 101 is located at the lower end of the support column 102. The cylinder body of the hydraulic cylinder 104 is fixedly connected to the fixing plate 103.

[0032] The punch 105 is fixedly connected to the piston of the hydraulic cylinder 104. The lower die 106 is fixedly connected to the base 101. The first sliding plate 107 is vertically slidably connected to the lower die 106. Specifically, the lower die 106 is provided with a guide hole 106a extending along the height direction of the lower die 106, and the first sliding plate 107 moves axially along the guide hole 106a. The two ends of the first spring 108 are fixedly connected to the first sliding plate 107 and the base 101, respectively. The limiting block 109 is fixedly connected to the lower die 106. The first slider 110 is horizontally slidably connected to the base 101. Specifically, the base 101 is provided with a first groove 101a extending along the length direction of the base 101, and the first slider 110 moves along the first groove 101a.

[0033] The drive block 112 is fixedly connected to the first slider 110. The transmission block 113 is fixedly connected to the first slide plate 107. The cylinder 114 is fixedly connected to the base 101, and the piston of the cylinder 114 is fixedly connected to the first slider 110. The drive block 112 includes a drive inclined surface, and the transmission block 113 includes a transmission inclined surface; the drive inclined surface abuts against the transmission inclined surface. The lower die 106 includes a mounting groove 106b, and the cylinder 114 is located within the mounting groove 106b. The transmission block 113 is located at the lower end of the first slide plate 107, the cylinder 114 is located on one side of the first slider 110, and the drive block 112 is located on the other side of the first slider 110. The limiting block 109 is located at the lower end of the first slide plate 107 and abuts against the first slide plate 107. Multiple sets of the lower die 106 and the punch 105 are provided. The hydraulic cylinder 104 is the power source of the mold. The piston of the hydraulic cylinder 104 is fixedly connected to the punch 105. The extension and retraction of the piston directly drives the punch 105 to move up and down.

[0034] The punch 105 is driven by a hydraulic cylinder 104, and its shape matches the final shape of the workpiece. During the pressing process, the punch 105 applies pressure to the workpiece 115, causing it to undergo plastic deformation within the forming cavity of the lower die 106, ultimately forming the desired shape. Both the lower die 106 and the punch 105 have multiple sets. Because both the lower die 106 and the punch 105 have multiple sets, the hydraulic cylinder 104 can simultaneously drive multiple punches 105 for synchronous stamping, ensuring that multiple workpieces are formed within the same timeframe. This achieves multi-cavity synchronous stamping, improving work efficiency.

[0035] Working principle: The workpiece 115 is placed in the forming cavity of the lower die 106. Then, the hydraulic cylinder 104 drives the punch 105 to stamp and form the workpiece 115. Then, the hydraulic cylinder 104 drives the punch 105 to reset. Next, the cylinder 114 drives the first slider 110 to move. The movement of the first slider 110 drives the drive block 112 to move. The drive block 112 drives the first slide plate 107 to move through the drive inclined surface and the transmission inclined surface, thereby making it easier for the workpiece 115 to be demolded.

[0036] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
