Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0028] See also Figures 1 to 7As shown, this embodiment provides an automatic waste material removal structure of a canopy forming and punching die, comprising an upper die 1 and a lower die 2. A ejection port 3 is provided on the mating surface of the upper die 1 corresponding to the hole position to be punched of the canopy product, and a receiving port 4 is provided on the mating surface of the lower die 2 corresponding to the ejection port 3. A ejection mechanism is provided in the back cavity of the upper die 1, and the ejection mechanism includes a ejector rod 5, which can extend or retract into the ejection port 3. A cavity 6 connected to the receiving port 4 is provided in the lower die 2, and a waste box 7 is provided in the cavity 6. The waste box 7 is used to receive the punching waste material pushed into the receiving port 4 by the ejector rod 5 and falling into the cavity 6.

[0029] Therefore, a material ejection mechanism is set for the holes to be punched in the canopy product, which realizes the function of automatically removing the punching residue after punching in the mold closing state, improves production efficiency, reduces the subsequent labor input, and reduces the production site cost.

[0030] Optionally, the ejection mechanism further includes a drive cylinder 8, which is fixed to the upper mold 1 via a mounting bracket 23, and the ejector rod 5 is coaxially fixedly connected to the output rod of the drive cylinder 8. The drive cylinder 8 here can be an oil cylinder, a pneumatic cylinder, an electric cylinder, etc., which provides ejection force for removing excess material.

[0031] Optionally, the ejection mechanism also includes a limit switch 9 connected to the signal of the driving cylinder 8, a support seat 10 is provided on the cylinder body of the driving cylinder 8, a follower plate 11 is provided on the output rod of the driving cylinder 8, and two travel rods 12 arranged in parallel and passing through the support seat 10 are provided on the follower plate 11. The limit switch 9 is located on one side of the two travel rods 12, one travel rod 12 is provided with a first travel block 13, and the other travel rod 12 is provided with a second travel block 14. When the ejector rod 5 is extended relative to the ejection port 3 and the first travel block 13 triggers the limit switch 9, the extension action of the ejector rod 5 stops; when the ejector rod 5 is retracted relative to the ejection port 3 and the second travel block 14 triggers the limit switch 9, the retraction action of the ejector rod 5 stops.

[0032] In this way, it is ensured that the ejector rod 5 can extend and retract within the set range, can be completely retracted into the upper die 1 in the retracted state, and can be prevented from extending excessively when ejecting excess material.

[0033] Furthermore, the limit switch 9 is also connected to the signal of the drive mechanism that controls the opening and closing of the upper mold 1 and the lower mold 2. When the second stroke block 14 triggers the limit switch 9, the drive mechanism can control the opening or closing of the mold to avoid damaging the ejector rod 5.

[0034] Optionally, a heat insulation plate 15 is provided between the mounting bracket 23 and the upper mold 1 to ensure that the working environment of the driving cylinder 8 and the limit switch 9 is not affected by the hot mold temperature.

[0035] Optionally, a bolster insert 16 is provided in the ejection port 3 , and a first through hole 17 is provided on the bolster insert 16 for allowing only the ejector rod 5 to pass through, thereby improving the position accuracy of the ejector rod 5 and ensuring the integrity of the mold surface of the upper mold 1 .

[0036] Optionally, a cutting edge insert 18 is provided in the material receiving port 4 , and a second through hole 19 is opened on the cutting edge insert 18 for allowing only the ejector pin 5 to pass through, thereby improving the position accuracy of the ejector pin 5 and ensuring the integrity of the mold surface of the lower mold 2 .

[0037] Optionally, a back plate 20 is provided on the back of the upper mold 1 , and an inspection port 21 is provided on the back plate 20 at a position corresponding to the ejection mechanism to facilitate maintenance of the ejection mechanism.

[0038] Optionally, a cleaning port 22 is provided on the side of the lower mold 2 , and the waste box 7 is taken out of or put into the cavity 6 through the cleaning port 22 so as to regularly clean the residual material.

[0039] Process flow: When closing the mold, the mold uses a cutting edge, and the remaining material after punching remains in the punching position; before opening the mold, the drive cylinder 8 is activated, driving the ejector rod 5 to extend until the first stroke block 13 triggers the limit switch 9, and the ejector rod 5 pushes the remaining material into the receiving port 4, and then the remaining material falls into the waste box 7 in the cavity 6; the drive cylinder 8 is reset, driving the ejector rod 5 to retract until the second stroke block 14 triggers the limit switch 9, and the ejector rod 5 is completely withdrawn into the ejection port 3; the mold is opened, and the molded canopy product is taken out.

[0040] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented.
