During the stamping process of the upper cover of the fan lamp, the first inner forming member 2710 moves towards the first die base 210 under the action of the first elastic member 2740.

[0053] In other embodiments, the first elastic member 2740 can also be disposed between the first outer forming member 2720 and the first die base 210, such that the first outer forming member 2720 can move relative to the first inner forming member 2710 in the vertical direction. At this time, the first inner forming member 2710 is fixedly connected to the first die base 210. During the stamping process of the upper cover of the fan lamp, the first outer forming member 2720 moves towards the first die base 210 under the action of the first elastic member 2740.

[0054] In this embodiment, the third elastic member 2510 is disposed between the first die base 210 and the first stamping assembly 250, such that the first stamping assembly 250 can move relative to the first die base 210 in the vertical direction under the action of the third elastic member 2510. In other embodiments, the third elastic member 2510 can also be correspondingly disposed in the second die assembly 300, that is, the third elastic member 2510 is disposed between the second die base 330 and the second stamping assembly 310, such that the second stamping assembly 310 moves relative to the second die base 330 in the vertical direction under the action of the third elastic member 2510.

[0055] It should be noted that all the movable screws used in this embodiment are for limiting the displacement distance of the corresponding movable components.

[0056] Please refer to Figures 2 to 3 As shown, the second die assembly 300 includes a second stamping assembly 310, a second backing plate 320, and a second die base 330 that are stacked from top to bottom. Among them, the second stamping assembly 310 and the second backing plate 320 are fixedly connected to the second die base 330.

[0057] The second die assembly 300 includes a second boundary member 340. The second boundary member 340 is disposed around the second stamping assembly 310 and the second backing plate 320. The position of the second boundary member 340 corresponds to that of the first boundary member 260. The surface of the second boundary member 340 facing the second stamping assembly 310 is flush with the surface of the first boundary member 260 facing the first stamping assembly 250.

[0058] The second die assembly 300 further includes a second forming assembly 350. The second forming assembly 350 is disposed on the side of the second die base 330 facing the first die assembly 200. The second stamping assembly 310 is disposed around the second forming assembly 350.

[0059] The second forming assembly 350 includes a second inner forming member 3510 and a second outer forming member 3520. The second inner forming member 3510 is fixedly connected to the second die base 330. The second outer forming member 3520 is disposed around the second inner forming member 3510.

[0060] Please refer to Figures 3 to 4 As shown, the second die assembly 300 further includes a second elastic member 3521 and a fourth elastic member 3410.

[0061] The second elastic member 3521 is disposed between the second die base 330 and the second forming assembly 350. In this embodiment, the second elastic member 3521 is disposed between the second outer forming member 3520 and the second die base 330, so that the second outer forming member 3520 can move relative to the second inner forming member 3510 in the vertical direction. That is, the second outer forming member 3520 is elastically connected to the second die base 330 through the second elastic member 3521. During the stamping and forming process of the upper cover of the fan lamp, the second outer forming member 3520 moves toward the second die base 330 under the action of the second elastic member 3521. After the stamping and forming is completed, the second outer forming member 3520 is reset under the action of the second elastic member 3521. A first limiting portion 3522 is provided on the side of the second outer forming member 3520 facing the second inner forming member 3510. The second inner forming member 3510 is correspondingly provided with a second limiting portion 3512. When the second outer forming member 3520 is reset, the first limiting portion 3522 abuts against the second limiting portion 3512 to limit the displacement of the second outer forming member 3520.

[0062] In other embodiments, the second elastic member 3521 can also be disposed between the second inner forming member 3510 and the second die base 330, such that the second inner forming member 3510 can move relative to the second outer forming member 3520 in the vertical direction. At this time, the second outer forming member 3520 is fixedly connected to the second die base 330. During the stamping process of the upper housing 400 of the fan lamp, the second inner forming member 3510 moves towards the second die base 330 under the action of the second elastic member 3521.

[0063] In this embodiment, the fourth elastic member 3410 is disposed between the second die base 330 and the second boundary member 340, such that the second boundary member 340 can move relative to the second die base 330 in the vertical direction. In other embodiments, the fourth elastic member 3410 can also be disposed between the first die base 210 and the first boundary member 260, such that the first boundary member 260 can move relative to the first die base 210 in the vertical direction.

[0064] Further, please refer to Figure 5 、 Figure 7 As shown, the second forming assembly 350 further includes a top block 3540. The top block 3540 is disposed on the side of the second inner forming member 3510 facing the first die assembly 200 and is movably connected to the second inner forming member 3510. Correspondingly, a fifth elastic member (not labeled) is disposed below the top block 3540. During demolding, the top block 3540 can move upward relative to the second inner forming member 3510 in the vertical direction, so that the upper housing 400 of the fan lamp is removed from the second die assembly 300. In this embodiment, the top block 3540 is an independent structure, and cooperating with the fifth elastic member makes the demolding effect better. In other embodiments, the top block 3540 can be integrally provided with the second inner forming member 3510.

[0065] When the first die assembly 200 and the second die assembly 300 cooperate with each other to stamp the upper housing 400 of the fan lamp, the first stamping assembly 250, the first forming assembly 270, the second stamping assembly 310, and the second forming assembly 350 cooperate together, and finally stamp the upper housing 400 of the fan lamp into shape.

[0066] Specifically, please refer to Figure 8 As shown, the upper housing 400 of the fan lamp includes a central region 410 and a blade mounting region 420 surrounding the central region 410. Please refer to Figures 6 to 7 As shown, the first forming assembly 270 is provided with a groove structure 2730 that is recessed in the direction approaching the first die base 210. The second forming assembly 350 is provided with a protrusion structure 3530 adapted to the groove structure 2730. The groove structure 2730 and the protrusion structure 3530 are combined to stamp and form the central region 410. The first stamping assembly 250 and the second stamping assembly 310 are combined to stamp and form the blade mounting region 420.

[0067] Further, after the first boundary member 260 and the second boundary member 340 are abutted against each other up and down, a stamping boundary of the upper housing 400 of the stamping fan lamp and a stamping area located within the stamping boundary are formed. The first stamping assembly 250 and the second stamping assembly 310 are arranged within the stamping area, thereby limiting the edge of the upper housing 400 of the fan lamp and playing a role in limiting the final forming of the upper housing 400 of the fan lamp.

[0068] The groove structure 2730 includes a first groove 2731 and a second groove 2732. The first groove 2731 is formed by the first forming surface 2711 of the first inner forming member 2710 facing the second die assembly 300 and being recessed inward. An annular recess 2721 is provided on one side of the first outer forming member 2720 close to the first inner forming member 2710. The annular recess 2721 and the first forming surface 2711 are connected to jointly form a second groove 2732 coaxial with the first groove 2731. The first groove 2731 and the second groove 2732 jointly form the groove structure 2730.

[0069] The protrusion structure 3530 includes a first protrusion 3531 and a second protrusion 3532. The second inner forming member 3510 includes a second forming surface 3511 opposite to the first forming surface 2711. The second forming surface 3511 is provided with a first protrusion 3531 matching the first groove 2731, and a second protrusion 3532 protruding relative to the second outer forming member 3520 and matching the second groove 2732. The first protrusion 3531 and the second protrusion 3532 jointly form the protrusion structure 3530.

[0070] When the upper cover of the fan lamp is stamping formed, the first protrusion 3531 abuts against the first groove 2731, and the second protrusion 3532 abuts against the second groove 2732. As the first die assembly 200 moves downward, the first inner forming member 2710 approaches the first die base 210, and the second outer forming member 3520 approaches the second die base 330, gradually stamping and forming the upper housing 400 of the fan lamp.

[0071] Please refer to Figure 9 As shown, a stamping side 3110 is formed on the surface of the second stamping assembly 310 facing the first die assembly 200. The stamping side 3110 includes a first end 3111 close to the second forming assembly 350 and a second end 3112 far from the second forming assembly 350. In the moving direction of the first die assembly 200, the plane where the first end 3111 is located is higher than the plane where the second end 3112 is located. Therefore, the stamping side 3110 is equivalent to forming a relatively protruding structure. Correspondingly, please refer to Figure 10 As shown, a relatively recessed extrusion side 2520 is formed on the surface of the first stamping assembly 250 facing the stamping side 3110. The stamping side 3110 and the extrusion side 2520 approach each other and are stamped to form the blade installation area 420.

[0072] At a position on the stamping side 3110 close to the second end 3112, there are circumferentially distributed third grooves 3113. The third grooves 3113 are recessed towards the direction of the second die base 330. The groove bottom surface of the third grooves 3113 is coplanar with the second end 3112. In this embodiment, the third grooves 3113 are used to fix the fan blades.

[0073] Furthermore, the stamping side 3110 includes a connecting surface (not shown) connecting the first end 3111 and the second end 3112. On the connecting surface, there are a plurality of reinforcing ribs 3114, and the plurality of reinforcing ribs 3114 are circumferentially spaced apart along the stamping side 3110. In fact, the reinforcing ribs 3114 are groove structures recessed relative to the connecting surface towards the second die base 330, and there is a height difference between the groove and the connecting surface. The reinforcing ribs 3114 can reinforce the strength of the fan blade installation area 420, preventing the upper shell 400 of the fan lamp formed by stamping from deforming due to external forces.

[0074] The first die assembly 200 includes a first positioning structure 280, and the second die assembly 300 includes a second positioning structure 360. One of the first positioning structure 280 and the second positioning structure 360 is a guide post, and the other is a guide sleeve. The guide post is slidably arranged relative to the guide sleeve so that the first die assembly 200 and the second die assembly 300 perform relative movement. In this embodiment, the first positioning structure 280 is a guide post, and the second positioning structure is a guide sleeve. Among them, the first positioning structure 280 is fixedly connected to the first die base 210, the second positioning structure 360 is fixedly connected to the second die base 330, and both the first positioning structure 280 and the second positioning structure 360 are arranged between the first die base 210 and the second die base 330.

[0075] In this embodiment, when the first die assembly 200 and the second die assembly 300 start stamping the upper shell 400 of the fan lamp, the first positioning structure 280 and the second positioning structure 360 first come into guiding contact. As the first die assembly 200 moves towards the second die assembly 300, the first positioning structure 280 moves within the second positioning structure 360.

[0076] In this embodiment, the in-mold forming device 100 can also be provided with a first support plate 290 above the first die base 210, and a pad 370 and a second support plate 380 below the second die base 330. The second support plate 380 is fixedly installed on the installation surface. The settings of the first support plate 290 and the second support plate 380 can enable the in-mold forming device 100 to carry a greater weight and ensure the stability of the in-mold forming device 100 during operation. It can be understood that the first support plate 290, the pad 370, and the second support plate 380 are not necessary, so in other embodiments, at least one of the first support plate 290, the pad 370, and the second support plate 380 can be omitted.

[0077] The working process of the in-mold forming device 100 according to the embodiments of the present utility model will be described in detail below.

[0078] When the first mold component 200 and the second mold component 300 are closed, the second mold component 300 remains stationary. The first positioning structure 280 and the second positioning structure 360 come into contact first. The first positioning structure 280 moves in the second positioning structure 360 towards the second mold component 300, thereby driving the entire first mold component 200 to move towards the second mold component 300. The first boundary member 260 and the second boundary member 340 abut against each other. At the same time, the first forming component 270 and the second forming component 350 abut against each other synchronously. The first elastic member 2740 and the third elastic member 2510 start to contract. The first inner forming member 2710 approaches the first mold base 210 under the action of the first elastic member 2740, and the first stamping component 250 approaches the first mold base 210 under the action of the third elastic member 2510. The second elastic member 3521 and the fourth elastic member 3410 start to contract. The second outer forming member 3520 approaches the second mold base 330 under the action of the second elastic member 3521, and the second boundary member 340 approaches the second mold base 330 under the action of the fourth elastic member 3410.

[0079] When the first mold component 200 continues to move downward, the groove structure 2730 and the protrusion structure 3530 are pressed and matched with each other, and the first stamping component 250 and the second stamping component 310 are pressed and matched with each other, so that the upper shell 400 of the fan lamp is slowly formed downward along the second stamping component 310 and the second forming component 350. And through the pressure of the first mold component 200 on the material, the material of the upper shell 400 of the fan lamp flows uniformly along the gap between the first stamping component 250 and the second stamping component 310, and finally the upper shell 400 of the fan lamp is formed.

[0080] When the forming is completed, please refer to Figure 5 As shown, the first mold component 200 and the second mold component 300 are opened simultaneously. The second outer forming member 3520 is reset under the action of the second elastic member 3521 and pushes the upper shell 400 of the fan lamp away from the second mold component 300.

[0081] In summary, the in-mold forming device 100 of the present utility model places the upper shell 400 material of the fan lamp in the stamping area formed by enclosing the first boundary member 260 and the second boundary member 340. The first forming assembly 270 and the second forming assembly 350 are combined to stamp and form the central area 410 of the upper shell 400 of the fan lamp, and the first stamping assembly 250 and the second stamping assembly 310 are combined to stamp and form the blade mounting area 420 of the upper shell 400 of the fan lamp. The in-mold forming device 100 of the present utility model does not rely on manual operation and can integrally stamp and form the upper shell 400 of the fan lamp without turnover, reducing the waiting time and errors that may occur in the traditional multi-step processing or assembly process. The in-mold forming device 100 can complete the forming of the entire upper shell 400 of the fan lamp in one operation cycle, greatly improving the production efficiency. Due to the reduction of production steps and required equipment, as well as the possible reduction of manual operations, the in-mold forming device 100 effectively reduces the production cost.
