The buckle plate 1431 engages with the first guide post 1411 to achieve tight closure of the mold.

[0072] In this embodiment, the movement trajectory of the buckle plate 1431 includes a first initial position and a first fixed position. When the buckle plate 1431 is in the first initial position, the buckle plate 1431 abuts against the ejector plate 1442, and the buckle plate 1431 limits the position of the ejector plate 1442. Figure 5 As shown; when the buckle plate 1431 is in the first fixed position, the buckle plate 1431 separates from the ejector plate 1442, and the buckle plate 1431 abuts against the connector 141 to achieve locking, as shown. Figure 6 As shown.

[0073] In this embodiment, the elastic buckle 143 also includes a positioning post 1433 and a mounting plate 1434. The mounting plate 1434 is connected to the lower mold 12. One end of the second elastic member 1432 is connected to the buckle plate 1431, and the other end abuts against the mounting plate 1434. The positioning post 1433 is disposed on one side of the mounting plate 1434, and the second elastic member 1432 is sleeved on the outside of the positioning post 1433, which improves the stability of the elastic buckle 143 during use.

[0074] Furthermore, the adaptive locking mechanism 14 also includes a positioning block 142 and a positioning groove 124. The positioning block 142 is disposed at the top of the connector 141, and its bottom end is connected to the bottom end of the upper mold 11; the positioning groove 124 is disposed at the top of the lower mold 12, and the positioning block 142 engages with the positioning groove 124, further enhancing the closing stability and accuracy of the mold. When the mold is closed, the positioning block 142 engages with the positioning groove 124, further enhancing the closing stability and accuracy of the mold.

[0075] The ejection mechanism 144 in this embodiment is described below:

The drive assembly also includes a reset rod 145, one end of which is connected to the ejector plate 1442, and the other end of which passes through the second guide hole 125 and extends outward. The reset rod 145 slides up and down along the second guide hole 125, thereby guiding the movement of the ejector plate 1442 and ensuring the stability of the ejector plate 1442 during movement.

[0082] The first elastic element 1443 connects the fixed base 1441 and the ejector plate 1442, pushing the ejector plate 1442 upward to lift the finished rubber corrugated product. The reset rod 145 has one end connected to the ejector plate 1442 and the other end passing through the vertical second guide hole 125 provided on the side wall of the lower mold 12 and extending thereafter.

[0083] In this embodiment, the movement trajectory of the ejector plate 1442 includes a second initial position, a preload position, and a second fixed position arranged sequentially from top to bottom. When the ejector plate 1442 is in the second initial position, the ejector pin 1444 extends out of the top of the lower mold 12, and the ejector pin 1444 lifts the rubber corrugated finished product, such as... Figure 7As shown; when the ejector plate 1442 is in the preload position, the latch plate 1431 is in the first fixed position, the positioning block 142 abuts against the ejector plate 1442, the positioning block 142 limits the position of the ejector plate 1442, and the ejector pin 1444 is located inside the lower mold 12, as shown. Figure 6 As shown; when the ejector plate 1442 is in the second fixed position, the latching plate 1431 is in the first initial position, the latching plate 1431 abuts against the ejector plate 1442, and the ejector pin 1444 is located inside the lower mold 12, as shown.

[0084] like Figure 4 As shown, in this embodiment, the adaptive locking mechanism 14 further includes a second guide post 146, which is vertically arranged in the lower mold 12. The ejector plate 1442 slides up and down along the second guide post 146, which improves the stability of the ejector plate 1442 during its up and down movement.

[0085] Combination Figure 2 and Figure 3 In this embodiment, the top of the lower mold 12 is also provided with an anti-slip groove 126, which is located on both sides of the second groove 121; the bottom of the upper mold 11 is provided with an anti-slip block 112, which fits into the anti-slip groove 126, thereby improving the stability of the upper mold 11 and the lower mold 12. Furthermore, the bottom portion of the anti-slip block 112 is used to seal the top of the second groove 121, thus sealing the upper mold 11 and the lower mold 12 to form a mold cavity 13.

[0086] In this embodiment, sealing strips 15 are also provided on both sides of the top of the lower mold 12. The sealing strips 15 are correspondingly located below the anti-slip block 112. When the upper mold 11 and the lower mold 12 are closed, the sealing strips 15 improve the sealing performance of the structure during use.

The first guide post 1411 of the connector 141 engages with the locking groove 122 of the lower mold 12, and through the interaction of the snap plate 1431 and the second elastic member 1432, the mold is tightly closed.

[0097] During the insertion of the first guide post 1411, the buckle plate 1431 is bent inward by the pressure of the first guide surface 1412 of the first guide post 1411.

[0098] When the first guide post 1411 is fully inserted into the locking groove 122, the buckle plate 1431 engages with the first guide post 1411 under the action of the second elastic element 1432, achieving self-adaptive locking.

[0099] Meanwhile, the positioning block 142 engages with the positioning groove 124, further enhancing the closing stability and precision of the mold.

[0100] The first elastic element 1443 pushes the ejector plate 1442 to move upward. When the ejector plate 1442 moves from the second initial position to the preload position, the positioning block 142 abuts against the ejector plate 1442, restricting the further rise of the ejector plate 1442. At this time, the ejector pin 1444 is still located in the lower mold 12, but is in a preparatory state for ejecting the finished product.

[0101] II. Vulcanization Molding

[0102] The semi-finished rubber product is placed in the mold cavity 13, filling the gap between the upper mold 11 and the lower mold 12. The semi-finished rubber product is heated and vulcanized in a vulcanizing machine, and then the material is allowed to cool and solidify to form the finished corrugated rubber product.

[0103] III. Mold opening and finished product ejection.

[0104] Applying external force lifts the upper mold 11 upward, causing the connector 141 to separate from the elastic latch 143, and the mold opens.

[0105] The first elastic element 1443 pushes the ejector plate 1442 upward, and the ejector plate 1442 moves from the preload position to the second fixed position. The ejector pin 1444 then extends out of the top of the lower mold 12 and lifts up the rubber corrugated finished product.

[0106] IV. Mold Reset

[0107] After the mold opens, the reset rod 145 guides the ejector plate 1442 to descend and reset, the adaptive locking mechanism 14 releases the locking force, and the ejection mechanism 144 ejects the finished product. The latch plate 1431 resets to its initial position under the action of the second elastic element 1432, awaiting the next mold closing. The positioning block 142 and the positioning groove 124 also reset to their initial state, ready for the next mold closing.

[0108] This completes the working process of the rubber corrugated protective cover flat vulcanization production mold of this preferred embodiment.

[0109] In this embodiment, the flat vulcanizing production mold and the vulcanizing machine body 21 work together. The vulcanizing machine body 21 provides the necessary heating and pressure environment. However, since the vulcanizing machine and its complex connection mechanism are not the main innovation of this application, they will not be described in detail here.

[0110] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
