[0026] See also Figure 1 and Figure 2 . Figure 1 This is a three-dimensional diagram of a mold with a secondary ejection demoulding mechanism according to an embodiment of the present invention. Figure 2 This is a top view of a mold with a secondary ejection and demoulding mechanism according to an embodiment of the present invention. As shown in the figure, the mold 1 includes a mold frame 11, a rear mold core 12, an ejection module 13 and a drive module 14.
[0027] The mold frame 11 has a mold frame hole at its center.
[0028] The rear mold core 12 is disposed in the mold frame hole and has a central hole.
[0029] The ejector module 13 is mounted within the central hole and includes two straight ejector inserts 131, two inclined ejector inserts 132, a guide block 133, and multiple push rods 134. The two inclined ejector inserts 132 are located on the left and right sides of the guide block 133, respectively, while the two straight ejector inserts 131 are located on the upper and lower sides of the guide block 133, respectively. A portion of the multiple push rods 134 is adjacent to one of the straight ejector inserts 131, while another portion of the multiple push rods 134 is adjacent to the other straight ejector insert 131. The number of these multiple push rods is an even number. In this embodiment, there are four push rods. Two of the push rods 134 are adjacent to one of the straight ejector inserts 131, while the other two push rods 134 are adjacent to the other straight ejector insert 131. In another embodiment, the number of these multiple push rods may be two or four or more; in yet another embodiment, the number of these multiple push rods may be an odd number. The number of push rods can vary depending on actual needs and is not limited to this. The ejection module 13 is engaged with the annular undercut of the product.
[0030] The driving module 14 is arranged under the mold frame 11 and is connected to the ejection module. The driving module 14 includes a base 141, a latch 142, a first top plate module 143, a second top plate module 144, a plurality of limit rods 145 and a plurality of ejector rods 146. The base 141 is connected to the first top plate module 143 and the two second top plates 144 through the latch 142. The structure of the latch 142 should be well known to those skilled in the art, so it will not be described in detail here. The first top plate module 143 includes two first top plates P1 stacked on each other, and the first top plate module 143 is connected to the ejection module 13 through the above-mentioned multiple limit rods 145 (in this embodiment, the number of the above-mentioned multiple limit rods 145 is 2, but it is not limited to this, and it can be increased or decreased according to actual needs). The second top plate module 143 includes two second top plates P2 stacked on each other, and the second top plate module 143 is connected to the ejection module 13 through the above-mentioned multiple ejector rods 146. The bottom end of each push rod 134 contacts the second ejector module 143. The drive module 14 can drive the ejector module 13 to perform a first-stage movement, causing the two straight ejector inserts 131, the two inclined ejector inserts 132, the guide block 133, and the plurality of push rods 134 to move upward synchronously, and then drive the ejector module 13 to perform a second-stage movement, causing the plurality of push rods 134 to move upward.

Through the above-mentioned secondary ejection and demoulding mechanism, the demoulding process can be carried out quickly and efficiently, and the demoulding process can be smoother, so that production efficiency is greatly improved. In addition, as can be seen from the above, the ejection module 13 of the mold 1 has an integrated design, so the structure can be greatly simplified, making the mold 1 easier to maintain and service. Therefore, the above-mentioned structural design can greatly reduce the maintenance cost and maintenance cost of the mold 1, thereby reducing the overall production cost. Therefore, the mold 1 can meet the needs of practical applications. Furthermore, the drive module 14 of the mold 1 can accurately execute the first stage movement and the second stage movement to accurately control the sequence and force of the above-mentioned secondary ejection and demoulding mechanism, so that product damage can be effectively prevented, the production process can be carried out smoothly, and the overall production cost can be further reduced.

[0032] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made to the mold with a secondary ejection demolding mechanism according to this embodiment should still be included in the patent scope of the present invention.
[0033] It's worth noting that many products feature annular undercuts, but these products often face demolding difficulties, resulting in poor production efficiency. Furthermore, to ensure smooth demolding, existing molds used to produce these products are often complex, making them difficult to maintain and service, significantly increasing production costs. Furthermore, existing molds used to produce these products lack precise control over the sequence and force of the ejection mechanism, which can easily cause product damage and hinder the smooth progress of the production process. In contrast, according to an embodiment of the present invention, a mold comprises a mold frame, a rear mold core, an ejection module, and a drive module. The mold frame has a mold frame hole. The rear mold core is positioned within the mold frame hole and has a central hole. The ejection module is positioned within the central hole and includes two straight ejector inserts, two inclined ejector inserts, a guide block, and multiple push rods. The two inclined ejector inserts are positioned on the left and right sides of the guide block, respectively, while the two straight ejector inserts are positioned on the top and bottom sides of the guide block, respectively. A portion of the multiple push rods is adjacent to one of the straight ejector inserts, while another portion of the multiple push rods is adjacent to the other straight ejector insert. The ejector module engages with the product's annular undercut. A drive module is positioned beneath the mold base and connected to the ejector module. The drive module drives the ejector module in a first-stage movement, disengaging the two straight and two angled top inserts from the guide blocks. This allows the two straight and two angled top inserts, along with the multiple push rods, to move upward synchronously. The drive module then drives the ejector module in a second-stage movement, moving the multiple push rods upward. This secondary ejection and demolding mechanism allows for a quick and efficient demolding process, making the demolding process smoother and significantly improving production efficiency.
[0034] Furthermore, according to the embodiments of the present invention, the mold's ejector module features an integrated design, significantly simplifying the structure and making mold maintenance and upkeep easier. Consequently, this structural design significantly reduces mold maintenance and upkeep costs, lowering overall production costs. Consequently, the mold can meet practical application requirements.
[0035] Furthermore, according to the embodiments of the present invention, the mold's drive module can precisely execute both the first and second stage movements to precisely control the sequence and force of the aforementioned secondary ejection and demolding mechanism. This effectively prevents product damage, allows for a smooth production process, and further reduces overall production costs. Consequently, the mold can be applied more widely to meet the needs of diverse applications. As can be seen from the foregoing, the mold with a secondary ejection and demolding mechanism according to the embodiments of the present invention can indeed achieve excellent technical results.
[0036] See also Figure 3 、 Figure 4 and Figure 5 , and please also refer to Figure 1 . Figure 3This is a schematic diagram of the first stage movement of a secondary ejection and demoulding mechanism according to an embodiment of the present invention. The ejection module and the annular undercut of the product are engaged with each other. Figure 4 This is a first schematic diagram of the second stage movement of a secondary ejection and demoulding mechanism according to an embodiment of the present invention. The ejection module and the annular undercut of the product are engaged with each other. Figure 5 This is a second schematic diagram of the second stage movement (product removal) of the secondary ejection demoulding mechanism according to an embodiment of the present invention. Figure 1 The state is the initial state of mold 1.
[0037] like Figure 3 As shown, the ejection module 13 and the annular undercut RX of the product are interlocked. The driving module 14 can drive the ejection module 13 to perform the first stage of movement. At this time, the buckle machine 142 controls the first top plate module 143 and the second top plate module 144 to move upward at the same time, and the above-mentioned multiple limiting rods 145 can pass through the second top plate module 144, but can only pass through the first top plate P1 on the upper side of the first top plate module 143, and cannot pass through the first top plate P1 on the lower side of the first top plate module 143, so as to achieve a limiting effect. The above-mentioned two straight top inserts 131 and the above-mentioned two inclined top inserts 132 are separated from the guide block 133, and the above-mentioned two straight top inserts 131, the above-mentioned two inclined top inserts 132 and the above-mentioned multiple push rods 134 are moved upward synchronously. The first stage of movement can achieve the effect of the first ejection, so that the outer side of the product is completely separated from the rear mold core 12. After the product is ejected for the first time, the two inclined top inserts 132 are separated from the buckle position of the product, and the buckle mechanism 142 stops moving after unlocking the two inclined top inserts 132 .
[0038] As shown in the figure, the height of one straight top insert 131 is greater than the height of the other straight top insert 131, the height of the two inclined top inserts 132, the height of the guide block 133 and the height of the plurality of push rods 134 before the second stage of movement.
[0039] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made to the mold with a secondary ejection demolding mechanism according to this embodiment should still be included in the patent scope of the present invention.
[0040] like Figure 4 and Figure 5As shown, the ejection module 13 is driven to perform the second stage of movement. At this point, the locking mechanism 142 controls the upward movement of the second ejector module 144, allowing the plurality of ejector pins 146 to pass through the second ejector module 144. However, the plurality of push rods 134 can only pass through the upper second ejector plate P2 of the second ejector module 144 and cannot pass through the lower second ejector plate P2 of the second ejector module 144. Therefore, the plurality of push rods 134 are pushed upward by the lower second ejector plate P2 of the second ejector module 144. This second stage of movement achieves a second ejection effect, allowing the plurality of push rods 134 to be ejected again. After the second stage of movement, the height of the plurality of push rods 134 is greater than the height of the two straight ejector inserts 131, the height of the two inclined ejector inserts 132, and the height of the guide block 133, thereby forcibly ejecting the product's annular undercut RX from the undercut of the plurality of straight ejector inserts 131.
[0041] By means of the above-mentioned secondary ejection demoulding mechanism, the demoulding process can be carried out quickly and efficiently, and the demoulding process can be smoother, thereby greatly improving production efficiency.
[0042] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made to the mold with a secondary ejection demolding mechanism according to this embodiment should still be included in the patent scope of the present invention.
[0043] In summary, according to an embodiment of the present invention, the mold includes a mold frame, a rear mold core, an ejection module and a drive module. The mold frame has a mold frame hole. The rear mold core is arranged in the mold frame hole and has a central hole. The ejection module is arranged in the central hole and includes two straight top inserts, two inclined top inserts, a guide block and a plurality of push rods. The two inclined top inserts are respectively arranged on the left and right sides of the guide block, and the two straight top inserts are respectively arranged on the upper and lower sides of the guide block. A portion of the multiple push rods is adjacent to one of the straight top inserts, and another portion of the multiple push rods is adjacent to the other straight top insert. The ejection module is engaged with the annular undercut of the product. The drive module is arranged under the mold frame and connected to the ejection module. The drive module drives the ejection module to perform a first-stage movement, disengaging the two straight and two slanted ejection inserts from the guide blocks and synchronously moving the two straight and two slanted ejection inserts and the plurality of push rods upward. The drive module then drives the ejection module to perform a second-stage movement, moving the plurality of push rods upward. This secondary ejection and demolding mechanism allows for a quick and efficient demolding process, making the demolding process smoother and significantly improving production efficiency.
[0044] Furthermore, according to the embodiments of the present invention, the mold's ejector module features an integrated design, significantly simplifying the structure and making mold maintenance and upkeep easier. Consequently, this structural design significantly reduces mold maintenance and upkeep costs, lowering overall production costs. Consequently, the mold can meet practical application requirements.
[0045] Furthermore, according to the embodiments of the present invention, the mold's drive module can precisely execute both the first and second phases of movement, accurately controlling the sequence and force of the secondary ejection mechanism. This effectively prevents product damage, ensures a smooth production process, and further reduces overall production costs. Consequently, the mold can be used in a wider range of applications to meet diverse requirements.
[0046] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection of the present utility model. Therefore, based on the innovative concept of the present utility model, changes and modifications to the embodiments described herein, or equivalent structural or process transformations made using the contents of the present utility model specification and drawings, and direct or indirect application of the above technical solutions to other related technical fields are all included in the scope of protection of the present utility model patent.
