For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0029] Figure 1 Schematic diagram of the product of the embodiment of the present disclosure when it explodes. Figure 1 In the related art, when a product 900 containing a bending insert 91 is formed by a mold, the bending insert 91 needs to be embedded in the mold first. Since the bending insert 91 is in a bent state, it is inconvenient to put it into the mold. In addition, in order to ensure that the bending insert 91 is firmly installed and accurately positioned after being embedded, the size of the accommodating part of the mold that can accommodate the bending insert 91 needs to be precisely matched with the size of the bending insert 91, and the dimensional accuracy of the mold is required to be relatively high.

[0030] In view of this, an embodiment of the present disclosure provides a lower mold assembly, which is not only convenient for the installation and entry of the bending insert 91, but also has low requirements on the dimensional accuracy of the mold. The lower mold assembly of the embodiment of the present disclosure is used to embed at least one bending insert 91. The bending insert 91 includes a first bending portion 911 and a second bending portion 912 that are relatively bent. Optionally, the first bending portion 911 extends along a horizontal straight line. The second bending portion 912 extends along a vertical straight line. The bending angle between the first bending portion 911 and the second bending portion 912 is 90 degrees, but it can be understood that the bending angle between the first bending portion 911 and the second bending portion 912 of the present disclosure includes but is not limited to this, and the bending angle of the bending insert 91 can be adaptively increased or decreased relative to 90 degrees.

[0031] Figure 2 Schematic diagram of the structure of the mold of the embodiment of the present disclosure when the mold is not closed. Figure 1 and Figure 2 The lower mold assembly 100 of the embodiment of the present disclosure includes at least one embedded part 10 and a lower mold 20.

[0032] Figure 3 FIG. 1 is a schematic diagram of the structure of the embedded component 10 according to an embodiment of the present disclosure. Figure 2 and Figure 3The embedded component 10 includes an embedded portion 11. The embedded portion 11 forms at least one first insertion hole 101 for inserting the first bent portion 911. Optionally, the first insertion hole 101 is formed on the peripheral side wall of the embedded component 10 and extends horizontally along a straight line, so as to allow the first bent portion 911 extending in a horizontal straight line to be inserted.

[0033] The lower mold 20 forms an embedded space 201 with an open top and at least one second insertion hole 202, and when the embedded portion 11 is embedded in the embedded space 201, the second bent portion 912 is inserted into the second insertion hole 202. Optionally, the second insertion hole 202 is formed on the top surface of the lower mold 20 and extends vertically along a straight line for the second bent portion 912 extending in a vertical straight line to be inserted. It is understandable that, since the bending angle and shape between the first bending portion 911 and the second bending portion 912 include but are not limited to this, the extension direction and opening direction of the first insertion hole 101 and the second insertion hole 202 include but are not limited to this, and can be adaptively adjusted according to the shape and bending angle of the bending insert 91.

[0034] Thus, when at least one of the bent inserts 91 is embedded in the lower mold 20, the relevant technicians can first insert the first bent portion 911 of the bent insert 91 into the first insertion hole 101, and then move the embedded component 10 downward while aligning it with the embedded space 201, so as to embed the embedded component 10 downward into the embedded space 201 with the top open. As the embedded component 10 is embedded downward, the second bent portion 912 of the bent insert 91 is gradually inserted downward. The second insertion hole 202, therefore, when the embedded part 10 is completely embedded in the embedded space 201, the second bent portion 912 is correspondingly inserted into the second insertion hole 202. At this time, since the first bent portion 911 and the second bent portion 912 have been correspondingly inserted into the embedded part 10 and the lower mold 20 of the lower mold assembly 100, the bending insert 91 is installed in the lower mold assembly 100, and in the above process, the bending insert 91 is easy to install.

[0035] In addition, compared to the method of embedding the entire bending insert 91 into the bending groove in the lower mold 20 as a whole, the first bending portion 911 and the second bending portion 912 of the bending insert 91 disclosed in the present invention are divided into two steps and are respectively inserted into the embedded part 10 and the lower mold 20. When the bending insert 91 is embedded, the dimensional accuracy requirement of the lower mold assembly 100 is low, which is conducive to ensuring the smooth embedding of the bending insert 91.

[0036] It is worth mentioning that the lower mold assembly 100 can also prepare the product 900 containing two or more bending inserts 91. At this time, each embedded part 10 can form two or more first insertion holes 101 for inserting two or more first bending portions 911 of each product 900. Two or more second insertion holes 202 can be formed on the lower mold 20 corresponding to each embedded space 201 for inserting two or more second bending portions 912 of each product 900. The number of embedded bending inserts 91 can be adaptively adjusted according to the needs of the product 900.

[0037] In addition, when the mold is used to mold a plurality of products 900 at one time to improve production efficiency, the embedded component 10 and the embedded space 201 may be multiple, and the multiple embedded components 10 and the multiple embedded spaces 201 are arranged in a one-to-one correspondence.

[0038] Optionally, the lower mold 20 includes a first lower mold 21 and at least one second lower mold 22. At least one second lower mold 22 is movably disposed on one side of the first lower mold 21, and a gap between the first lower mold 21 and the second lower mold 22 forms the embedded space 201. Specifically, there may be a plurality of second lower molds 22, and a plurality of embedded spaces 201 are formed between the plurality of second lower molds 22 and the first lower mold 21.

[0039] Optionally, the moving direction of the second lower mold 22 is the same as the extending direction of the first insertion hole 101. The second lower mold 22 forms a first docking portion 2201. The embedded part 10 includes a second docking portion 12. The second docking portion 12 is connected to the embedded part 11, and docks with the first docking portion 2201 when the embedded part 11 is embedded in the embedded space 201, so that the second lower mold 22 can drive the embedded part 10 to disengage from the first bending portion 911 when the second lower mold 22 moves.

[0040] Therefore, when the embedded component 10 is embedded in the embedded space 201, the first docking portion 2201 and the second docking portion 12 are docked, so that the embedded component 10 is connected to the second lower mold 22, so that when the second lower mold 22 moves away from the first lower mold 21, the embedded component 10 is also driven by the second lower mold 22 to move away from the first lower mold 21 accordingly, and then the embedded component 10 can be pulled out from the first bending portion 911, so that the product 900 can be easily demolded after molding.

[0041] In some examples, the first docking portion 2201 is formed as a plug hole extending in a vertical direction. The second docking portion 12 is formed as a plug portion adapted to the plug hole. The plug portion is connected to the embedded portion 11, and when the embedded portion 11 is embedded in the embedded space 201, the plug portion is plugged into the plug hole.

[0042] In other examples, the second lower mold 22 forms a plug-in portion, the embedded component 10 forms a plug-in hole extending vertically and adapted to the plug-in portion, and when the embedded portion 11 is embedded in the embedded space 201, the plug-in portion is plugged into the plug-in hole.

[0043] Therefore, when the embedded component 10 is embedded in the embedded space 201, due to the plug-in cooperation between the plug-in hole and the plug-in portion, the embedded component 10 is connected to the second lower mold 22, so that when the second lower mold 22 moves away from the first lower mold 21, the embedded component 10 is also driven by the second lower mold 22 to move away from the first lower mold 21 accordingly, so that the embedded component 10 can correspondingly detach from the first bending portion 911.

[0044] Figure 4 Schematic diagram of the structure of the lower mold assembly at an angle according to an embodiment of the present disclosure. Figure 2 and Figure 4 The lower mold assembly 100 further includes a bottom mold 23. The first lower mold 21 is positioned and installed on the bottom mold 23. The bottom mold 23 forms a sliding notch 2301 located on one side of the first lower mold 21, and the sliding notch 2301 is slidably matched with the second lower mold 22.

[0045] Therefore, when the second lower mold 22 moves closer to or away from the first lower mold 21, the sliding notch 2301 can guide the second lower mold 22, so that the second lower mold 22 can move smoothly and steadily in a direction away from or toward the first lower mold 21.

[0046] Specifically, in some examples, after the upper mold 300 that cooperates with the lower mold assembly 100 is opened, the second lower mold member 22 can be driven by a linear drive member such as a cylinder to move accordingly.

[0047] In some other examples, the second lower mold 22 may also be moved away from the first lower mold 21 when the upper mold 300 and the lower mold assembly 100 are opened. Specifically, Figure 5 yes Figure 4 Schematic diagram of the structure at another angle. Figure 2 and Figure 5The second lower mold 22 forms an insertion and extraction space 2202 with one side open for the oblique column 31 of the upper mold 300 to be inserted and removed. For example, the oblique column 31 is fixed below the upper mold 300 and can move together with the upper mold 300 to move up accordingly when the upper mold 300 moves up, and move down accordingly when the upper mold 300 moves down.

[0048] The lower mold assembly 100 further includes a swinging member 24 and an elastic member 25. The swinging member 24 can swingably stop against the inner wall of the plug-in space 2202, and at least partially close the open opening 2203 of the plug-in space 2202. When the inclined column 31 moves downward, the swinging member 24 is driven by the inclined column 31 to move in a direction away from the open opening 2203 to open the open opening 2203, so that the inclined column 31 can enter the plug-in space 2202 through the open opening 2203. When the inclined column 31 moves upward to pull out the plug-in space 2202, the swinging member 24 is pushed by the inclined column 31 to drive the second lower mold 22 to move in a direction away from the first lower mold 21.

[0049] In other words, when the upper mold 300 and the lower mold 20 are not in mold closing, the swing member 24 stops against the inner wall of the plugging and unplugging space 2202 and at least partially closes the opening 2203. When the upper mold 300 moves downward to close the lower mold 20, the upper mold 300 moves downward to drive the inclined column 31 to move downward, and the downward movement of the inclined column 31 drives the swing member 24 to swing away from the opening 2203, so that the inclined column 31 can enter the plugging and unplugging space 2202 through the opening 2203.

[0050] Optionally, the swing component 24 includes a first swing member 241 and a second swing member 242. The first swing member 241 can swingably stop against the inner wall of the plug-in space 2202. The second swing member 242 can swingably stop against the inner wall of the plug-in space 2202, and cooperate with the first swing member 241 to close the open mouth 2203. Therefore, when the inclined column 31 moves downward, the first swing member 241 and the second swing member 242 are driven by the inclined column 31 to swing in a direction away from the open mouth 2203 to open the open mouth 2203, so that the inclined column 31 passes through the open mouth 2203 and then enters the plug-in space 2202 through the gap between the first swing member 241 and the second swing member 242.

[0051] The elastic component 25 is disposed between the swing component 24 and the second lower mold 22 , and is used to keep the swing component 24 at a position where it abuts against the inner wall of the plug-in space 2202 and at least partially closes the open opening 2203 .

[0052] In other words, after the inclined column 31 enters the plug-in space 2202, the elastic component 25 drives the swing component 24 to return from the position away from the open mouth 2203 to the position where it abuts against the inner wall of the plug-in space 2202 and at least partially closes the open mouth 2203. At this time, the swing component 24 can no longer continue to swing along the return direction. Therefore, when the upper mold 300 moves up to open the mold with the lower mold 20, the upper mold 300 moves up to drive the inclined column 31 to move up, and the inclined column 31 moves up to push the swing component 24, so that the swing component 24 pushes the second lower mold 22 to move away from the first lower mold 21, so that the second lower mold 22 moves away from the first lower mold 21. In the above process, since the swing component 24 will swing to avoid the inclined column 31 during the process of the inclined column 31 entering the plug-in space 2202, the inclined column 31 is difficult to be damaged by collision.

[0053] Specifically, after the inclined column 31 enters the plug-in space 2202, driven by the elastic component 25, the first swinging member 241 and the second swinging member 242 gather together to return to the position of cooperating to close the open opening 2203, so that when the inclined column 31 moves upward, the inclined column 31 can push the first swinging member 241 and the second swinging member 242 to push the second lower mold 22 away from the first lower mold 21.

[0054] Optionally, the elastic component 25 includes a first elastic member 251 and a second elastic member 252. The first elastic member 251, such as a first torsion spring, is disposed between the first swing member 241 and the second lower mold 22, and is used to keep the first swing member 241 in a state of abutting against the inner wall of the plug-in space 2202. Thus, after the first swing member 241 swings away from the open mouth 2203, the first elastic member 251 can drive the first swing member 241 to reset, so that the first swing member 241 returns to a position of abutting against the inner wall of the plug-in space 2202. The second elastic member 252, such as a second torsion spring, is disposed between the second swing member 242 and the second lower mold 22, and is used to keep the second swing member 242 in a state of abutting against the inner wall of the plug-in space 2202. Therefore, after the second swinging member 242 swings in a direction away from the open opening 2203 , the second elastic member 252 can drive the second swinging member 242 to return to the position where the second swinging member 242 abuts against the inner wall of the plugging space 2202 .

[0055] Figure 6 is a cross-sectional view of a mold according to an embodiment of the present disclosure. Figure 2 and Figure 6 , the embodiment of the present disclosure also provides a mold. The mold includes the lower mold assembly 100 and the upper mold 300 as described above. The upper mold 300 cooperates with the lower mold assembly 100 to form at least one molding cavity 301 that can accommodate at least part of the bending insert 91. Therefore, after the product raw material is injected into the molding cavity 301, the product raw material will be coated on the outside of the bending insert 91, so that the molding cavity 301 can mold the product 900 containing the bending insert 91.
