[0054] refer to Figure 1 , Figure 2 The present application proposes a side push forming mold, which includes an upper mold assembly 100, a lower mold assembly 200 and a side mold assembly 300.

[0055] The upper die set 100 is connected to the driving structure, and moves up and down relative to the lower die set 200 under the action of the driving structure.

[0056] The side mold group 300 is disposed between the upper mold group 100 and the lower mold group 200 . The side mold group 300 converts the up and down movement of the upper mold group 100 into its own horizontal movement, thereby realizing a lateral pushing action on the formed piece 500 placed between the upper mold group 100 and the lower mold group 200 .

[0057] refer to Figure 3-Figure 9 Specifically, the upper mold assembly 100 includes an upper mold plate 101 and an upper positioning member 120 disposed below the upper mold plate 101. The upper positioning member 120 can be integrally formed with the upper mold plate 101, or can be a separate structure from the upper mold plate 101 and fixed below the upper mold plate 101 by mechanical connection or the like.

[0058] The lower mold assembly 200 includes a lower mold plate 201 and a lower positioning member 411 disposed above the lower mold plate 201 . The upper positioning member 120 and the lower positioning member 411 are used to clamp the formed member 500 .

[0059] That is, before the upper mold assembly 100 moves down to close the mold, the molded part 500 is placed on the lower mold assembly 200 in advance.

[0060] During the mold closing process, the upper positioning member 120 and the lower positioning member 411 clamp and fix the formed member 500 to prevent the formed member 500 from moving under the thrust of the side mold assembly 300 during the side pushing process of the side mold assembly 300 .

[0061] According to the specific shape of the formed piece 500 , an upper positioning surface 121 matching the outer shape of the corresponding position of the formed piece 500 is formed on the lower surface of the upper positioning piece 120 in contact with the formed piece 500 .

[0062] A lower positioning surface 412 matching the shape of the position of the forming member 500 is formed on the upper surface of the lower positioning member 411 that contacts the forming member 500 .

[0063] The specific arrangement positions and quantities of the upper positioning member 120 , the lower positioning member 411 and the side mold assembly 300 are determined according to the specific forming requirements of the forming member 500 .

[0064] refer to Fig.12 , Fig.15 Taking the formed part 500 as a TV back panel as an example, the TV back panel is rectangular and three end faces thereof need to be pushed sideways.

[0065] The forming of the back panel of a television requires multiple steps. First, a rectangular sheet metal material of corresponding size needs to be obtained, stretched into a disc shape, and then shaped. The three sides of the rectangular sheet metal material are bent at target angles to form an arc-shaped positioning segment 510. Then, the outer side of the positioning segment 510 is bent downward 90 degrees to form a formed vertical portion 530 perpendicular to the sheet metal surface.

[0066] The purpose of the side push forming die is to bend the end of each forming vertical portion 530 inwardly to a target angle, for example but not limited to, a 90-degree inward push bend to form an inwardly bent end portion 531 at the end of the forming vertical portion 530 .

[0067] The formed transverse portion 520 , the formed vertical portion 530 and the bent end portion 531 together form a C-shaped bend of the back panel of the television.

[0068] Each side mold assembly 300 realizes the side push forming of the bent end portion 531 at the corresponding position.

[0069] Take one of the side mold groups 300 as an example for detailed description:

[0070] The side mold assembly 300 includes a support seat 220, a forming slider 310 and a pressing block 320. The support seat 220 is fixed on the lower mold plate 201. The position of the support seat 220 is fixed, and it serves as a foundation for connecting the forming slider 310 and the pressing block 320.

[0071] refer to Figure 3 , Figure 4 In some embodiments of the present application, the forming slider 310 is connected to the support seat 220 through the first elastic member 350. During the process of opening and closing the mold, the forming slider 310 moves horizontally on the surface of the lower mold plate 201 to realize the side pushing process of the forming cross portion 520 of the formed part 500.

[0072] The pressing block 320 is connected between the support seat 220 and the forming slider 310. A driving surface 321 inclined from bottom to top toward the forming slider 310 is formed on the side of the pressing block 320 close to the forming slider 310. A follower surface 311 adapted to the driving surface 321 is formed on the forming slider 310. The pressing block 320 is connected to the support seat 220 and the forming slider 310 in a contact manner.

[0073] Under the action of the driving surface 321 and the following surface 311 , the pressing block 320 and the forming slide block 310 move in the vertical direction and the horizontal direction respectively.

[0074] Specifically, in the mold opening state, the top of the pressing block 320 is higher than the forming slider 310 by a certain height. During the mold closing process, as the upper mold plate 101 moves downward, the driving block 110 located directly above the pressing block 320 gradually approaches the pressing block 320 .

[0075] A driving block 110 extending downward is formed on the upper mold plate 101 . The driving block 110 is located directly above the pressing block 320 and is used to drive the pressing block 320 to move downward.

[0076] After the driving block 110 contacts the pressing block 320, as the upper template 101 moves downward, the driving block 110 presses the pressing block 320 downward. Under the action of the driving surface 321 and the following surface 311, the pressing block 320 forms a horizontal thrust on the forming module, moving the forming module to a position away from the support seat 220.

[0077] During this process, the first elastic member 350 is gradually stretched, and in the mold closing state, the first elastic member 350 is in a stretched state.

[0078] Specifically, the first elastic member 350 is connected to one end of the support seat 220 away from the forming slider 310, and a penetrating connecting hole is formed in the support seat 220. One end of the first connecting member 340 is connected to the first elastic member 350, and the other end passes through the connecting hole and is connected to the forming slider 310.

[0079] After the side-pushing process is completed, the upper template 101 moves upward, and the driving block 110 moves upward accordingly, gradually releasing the pressing block 320 . Under the restoring force of the first elastic member 350 itself, the forming slider 310 moves toward the direction close to the support seat 220 .

[0080] The cooperation between the driving surface 321 and the following surface 311 enables the forming slider 310 to provide an upward force on the pressing block 320 , thereby driving the pressing block 320 to reset upward relative to the support seat 220 and the forming slider 310 .

[0081] refer to Figure 5 , Figure 6 In some other embodiments of the present application, in order to further improve the stability of the pressing block 320 during the resetting process, the pressing block 320 is connected to the lower mold assembly 200 through the second elastic member 210.

[0082] The bottom of the second elastic member 210 is fixed on the lower template 201 , and the upper end of the second elastic member 210 is connected and fixed to the pressing block 320 via the second connecting member 330 .

[0083] The second connecting member 330 and the pressing block 320 are fixedly connected via a fastener 331 .

[0084] During the mold closing process, as the pressing block 320 moves downward, the second elastic member 210 is gradually compressed. In the mold closing state, the second elastic member 210 is in a compressed state.

[0085] When the mold is opened, the pressing block 320 is pushed upward under the action of the self-restoring force of the second elastic member 210. Since the pressing block 320 and the second connecting member 330 are fixedly connected by the fastener 331, the maximum upward displacement of the pressing block 320 can be limited to prevent the pressing block 320 from falling out from between the forming slider 310 and the support seat 220.

[0086] refer to Figure 7 , Figure 8 In some other embodiments of the application, the second connecting member 330 is in contact connection with the bottom of the pressing block 320, thereby reducing the use of the fastener 331 and lowering the cost of assembly and disassembly.

[0087] Similar to the previous embodiment, during the mold closing process, as the pressing block 320 moves downward, the second elastic member 210 is gradually compressed. In the mold closing state, the second elastic member 210 is in a compressed state.

[0088] When the mold is opened, the pressing block 320 is pushed upwards by the self-restoring force of the second elastic member 210 .

[0089] In order to avoid interference, the second connecting member 330 and the first connecting member 340 are staggered in position.

[0090] The length of the forming slide block 310 matches the length of the corresponding forming vertical portion 530 of the forming piece 500 . A plurality of pressing blocks 320 may be arranged at intervals along the length direction of the corresponding forming slide block 310 to provide a stable thrust to the forming slide block 310 .

[0091] The first connecting member 340 connected to the forming slider 310 is spaced apart from the pressing block 320 to ensure that the forming slider 310 is pushed and pulled stably, and can be staggered with the pressing block 320 to avoid interference.

[0092] In order to further display the upward displacement of the pressing block 320 during the resetting process, a limiting member 230 is further provided above the support seat 220. The limiting member 230 is formed with a limiting end 232 extending toward the pressing block 320 for limiting the maximum upward displacement of the pressing block 320.

[0093] The limiting member 230 is fixed to the upper surface of the support seat 220 by means of a fixing screw 231 , and the driving block 110 and the limiting end portion 232 are staggered in position to avoid interference.

[0094] Combination Figure 12-Figure 17 Since a forming transverse portion 520 is also formed on the forming piece 500, the forming transverse portion 520 is located between the positioning section 510 and the forming vertical portion 530, and for the back panel of the TV, the forming slider 310 only pushes the bent end portion 531 at the end of the forming vertical portion 530.

[0095] Combination Fig. 9 In order to support the upper ends of the formed horizontal portion 520 and the formed vertical portion 530 , in other embodiments of the present application, an intermediate module 400 is further provided on the lower template 201 , and a lower positioning member 411 is formed on the intermediate module 400 .

[0096] The middle mold assembly 400 includes a middle mold base 410 and an auxiliary positioning member 420 . The middle mold base 410 is vertically movably connected to the lower mold plate 201 via a third elastic member 250 , and the auxiliary positioning member 420 is horizontally movably connected to the middle mold base 410 via a fourth elastic member 430 .

[0097] The lower end of the third elastic member 250 is fixed on the lower mold plate 201 , and the middle mold base 410 is connected to the upper end of the third elastic member 250 via the third connecting member 260 .

[0098] During the mold closing process, as the upper mold assembly 100 moves downward, the middle mold assembly 400 also moves downward under the drive of the upper mold assembly 100 to compress the third elastic member 250 .

[0099] During the mold opening process, the upper mold assembly 100 moves upward, and the middle mold assembly 400 is reset upward under the restoring force of the third elastic member 250 .

[0100] A horizontal mounting hole is formed on the middle mold base 410, and one end of the fourth elastic member 430 is connected to the mounting hole and is connected to the middle mold base 410 through a fourth connecting member 431. The fourth elastic member 430 is configured so that when the mold is closed, the fourth elastic member 430 is deformed, stretched or compressed, and when the mold is opened, the fourth elastic member 430 is reset under the action of its own restoring force.

[0101] The first elastic member 350 , the second elastic member 210 , the third elastic member 250 and the fourth elastic member 430 are elastic structures such as return springs.

[0102] The first connecting member 340 , the second connecting member 330 , the third connecting member 260 and the fourth connecting member 431 are connecting structures such as connecting screws.

[0103] A lower support portion 413 extending horizontally toward the side module 300 is formed at the bottom of the middle module 400 , and the auxiliary positioning member 420 is movably connected to the lower support portion 413 .

[0104] The lower support portion 413 is formed integrally with the middle mold base 410 .

[0105] Specifically, the middle mold base 410 is also provided with an upwardly extending auxiliary support block 240 , on which a support slope 241 extending from top to bottom toward the forming slider 310 is formed, and on the auxiliary positioning member 420 a matching surface 422 matched with the support slope 241 is formed.

[0106] Under the action of the supporting inclined surface 241 and the matching surface 422 , as the middle module 400 rises and falls, the auxiliary positioning member 420 moves horizontally relative to the lower supporting portion 413 .

[0107] During the mold closing process, the auxiliary positioning piece 420 moves downward with the middle mold assembly 400. Under the action of the mating surface 422 and the supporting inclined surface 241, the auxiliary support block 240 applies a force on the auxiliary positioning piece 420 in the direction of the forming slider 310, moving the auxiliary positioning block in the direction of the forming slider 310.

[0108] During the movement of the auxiliary positioning block, the fourth elastic member 430 is stretched.

[0109] When the molding is completed and the mold is opened, the auxiliary positioning member 420 is reset under the restoring force of the fourth elastic member 430 and is released from the molded member 500, so as to facilitate demolding.

[0110] In order to avoid interference, a through installation opening is provided at the bottom of the middle mold base 410 , and the auxiliary support block 240 extends from the installation opening to above the lower support portion 413 and is in contact and connection with the auxiliary support member.

[0111] A positioning protrusion 421 is formed at one end of the auxiliary positioning member 420 close to the forming slider 310 , and the vertical height between the bottom surface of the positioning protrusion 421 and the top surface of the forming slider 310 is adapted to the thickness of the formed member 500 .

[0112] Between molds, the formed part 500 is supported on the middle mold 400, and the forming vertical part 530 extends between the middle mold 400 and the side push mold. As the upper mold 100 moves downward, the forming slider 310 moves toward the forming vertical part 530, and at the same time, the auxiliary positioning part 420 also moves toward the formed part 500.

[0113] After the auxiliary positioning member 420 is moved into position, the positioning protrusion 421 at the front end of the auxiliary positioning portion moves to the bottom of the forming cross portion 520 to provide support for the forming cross portion 520 to prevent it from being deformed.

[0114] At the same time, the forming slide 310 pushes the bent end portion 531 at the lower end of the forming vertical portion 530 inward to form an inward 90-degree bend.

[0115] Of course, in addition to forming a 90-degree bend between the forming vertical portion 530 and the bending end portion 531, other angles can also be formed, and the shape of the corresponding forming slider 310 and the shape of the positioning protrusion 421 can be adaptively designed.

[0116] The side-push forming mold involved in the present application has a simple overall structure. When the upper mold assembly 100 descends to position the formed part 500, it also provides power for the side mold assembly 300 to push sideways. The action process is simple, the stability is high, and the forming effect is good.

[0117] The number of side mold groups 300 can be set in multiples according to the actual forming requirements of the formed piece, and each forming position of the formed piece 500 is synchronously acted on, thereby improving the forming efficiency;

[0118] The upper positioning member 120 , the lower positioning member 411 and the auxiliary positioning member 420 cooperate with each other to position the formed member 500 , effectively preventing the formed member 500 from being deformed during the mold opening and closing process, and achieving a good forming effect.

[0119] During the specific working process of the side-thrust forming mold, the fastening screws, springs and other moving parts inside its structure may become loose and fall out during a long production process, and the formed part 500 may drop debris and squeeze out zinc powder. The fallen parts and fallen debris accumulate in the gap between the middle module 400 and the forming slider 310, hindering the normal movement of the forming slider 310 and the middle module 400, and easily damaging the mold.

[0120] refer to Figure 3 , Figure 4 , Fig.10 , Fig.11 In order to solve the above problem, in other embodiments, a downwardly extending receiving groove 270 is further formed on the surface of the lower mold plate 201 , and the receiving groove 270 is located between the forming slider 310 and the middle mold assembly 400 .

[0121] In case that the forming part 500 has multiple forming positions, take the forming part 500 as a TV back panel with three forming vertical parts formed on its peripheral side as an example. Correspondingly, three groups of side mold groups 300 are correspondingly arranged on the lower mold group 200. Then, an accommodating groove 270 is arranged between each side mold group 300 and the middle mold group 400.

[0122] That is, the accommodating groove 270 on the lower template 201 is shaped like a concave character as a whole.

[0123] In the open mold state, the forming slider 310 is located on one side of the accommodating groove 270. During the mold closing process, the forming slider 310 moves toward the middle template on the surface of the lower template 201. In the closed mold state, part of the forming slider 310 is located directly above the accommodating groove 270. The front end surface of the bottom of the forming slider 310 can push foreign objects on the lower template 201 forward into the accommodating groove 270.

[0124] The middle module 400 moves in the vertical direction. When the middle module 400 moves downward and contacts the lower template 201, foreign objects fall into the accommodating groove 270 and will not interfere with the foreign objects in the accommodating groove 270, thus avoiding the problem of interference when the middle module 400 moves downward when foreign objects fall.

[0125] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0126] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by technicians familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
