A bending groove molding cavity 303 is provided on one side of the top of the slanted top body 301, and one end of the elastic structure 302 is connected to the bending groove molding cavity 303. When the slanted top component 3 moves obliquely, the elastic structure 302 exerts pressure on the bending structure 5 to produce elastic deformation, so that the bending structure 5 is demolded.

[0030] The front mold assembly 1 is provided with a front mold core 101, and the rear mold core 201 is provided at the rear assembly below the front mold assembly 1. The front mold core 101 and the rear mold core 201 are combined to form a molding cavity. The inclined top assembly 3 is arranged on the rear mold assembly 2, including an inclined top body 301 and an elastic structure 302. The inclined top assembly 3 has molding and demoulding functions. The lower part of the inclined top assembly 3 can be adapted to a variety of ejection structures and guide structures 4. A curved groove molding cavity 303 is provided on one side of the top of the inclined top body 301. The molding cavity can be combined with the rear mold core 201 to form a complete The entire molding cavity can also be combined with other structures to form a complete molding cavity. The elastic structure 302 of the inclined top component 3 can be arranged inside the inclined top body 301, or it can be fixed on the inclined top body 301. One end of the elastic structure 302 is connected to the bending groove molding cavity 303, so that after the product is formed, one end of the elastic structure 302 is in contact with the bending structure 5. When the inclined top component 3 moves obliquely to eject the molded product during demolding, the elastic structure 302 applies pressure to the bending structure 5, causing the bending structure 5 to produce elastic deformation and demold smoothly.

The receiving groove 306 matches the shape of the elastic structure 302 to facilitate the relative sliding of the elastic structure 302 in the receiving groove 306. The receiving groove 306 is connected with the bending groove forming cavity 303, so that after molding, the elastic structure 302 abuts against the bending structure 5 through the connecting position, which is convenient for demolding.

[0033] Furthermore, if Figure 4-6 As shown, the elastic structure 302 includes a top block 307 that slides relatively in the accommodating groove 306 , one end of the top block 307 is a protruding end 308 that protrudes from the inclined top side wall, and the other end is connected to the curved groove forming cavity 303 .

[0034] The elastic structure 302 includes a top block 307 that slides relatively in the accommodating groove 306. The top block 307 can be a cylindrical, T-shaped or other structure suitable for ejecting molded parts. One end of the top block 307 protrudes from the inclined top side wall to facilitate pressing the elastic structure 302. The other end of the top block 307 is connected to the bending groove molding cavity 303. The protruding end 308 of the elastic structure 302 is pressed, so that the other end is ejected, and the bending structure 5 is compressed to produce elastic deformation, which is convenient for demolding.

[0035] Furthermore, if Figure 6 As shown, the elastic structure 302 further includes an elastic member 304 , and the elastic member 304 is disposed outside the top block 307 .

[0036] The elastic member 304 is arranged on the outside of the top block 307. When one side of the top block 307 is pressurized, the elastic member 304 is compressed.

A groove 203 is provided on one side of the sliding groove 202, and the position of the groove 203 corresponds to the protruding end of the top block 307. When the mold is opened, the inclined top component 3 moves obliquely through the sliding groove 202, and the distance between the inner wall of the groove 203 and the inclined top body 301 is gradually shortened. The protruding end of the top block 307 is squeezed by the inner wall of the groove 203, so that the top block 307 moves in the accommodating groove 306, so that the other end of the top block 307 is ejected, which is convenient for the bending structure 5 to be demoulded.

[0043] Furthermore, if Figure 6-8 As shown, an inclined surface is provided at the upper end of the groove 203 , and a platform 305 matching the inclined surface on the groove 203 is provided at the top of the inclined top body 301 .

[0044] An inclined surface is provided at the upper end of the groove 203, so that the top block 307 rebounds and resets immediately after being pressed out of the bending structure 5 without affecting the subsequent demolding. A platform 305 is provided on the top of the inclined top body 301 that cooperates with the inclined surface on the groove 203, which facilitates the positioning of the inclined top body 301 and the oblique displacement of demolding without interference.

[0046] The position where the receiving groove 306 communicates with the bending groove forming cavity is set at the end of the bending groove forming cavity, which is convenient for directly ejecting the end of the bending hook during demoulding to prevent the bending structure 5 from being incompletely ejected during demoulding.

[0047] Furthermore, if Figure 3-5 As shown, the inclined top assembly 3 includes a guide structure 4 installed on the rear mold assembly 2, and the guide structure 4 includes a guide base 401 provided with a guide groove, a protrusion 402 arranged at the bottom of the inclined top body 301 and matching with the guide base 401, and a guide block 403 installed on the rear mold assembly 2.

[0048] The inclined top assembly 3 is provided with a guide structure 4, which includes a guide base 401 with a guide groove. The guide base 401 can be other guide structures 4 such as H-type, L-type or dovetail type. A protrusion 402 matching the guide groove of the guide base 401 is provided at the bottom of the inclined top body 301. The protrusion 402 slides relatively in the guide groove of the guide base 401 to facilitate the sliding of the inclined top assembly 3 during demolding and mold closing. The guide block 403 guides the inclined top assembly 3 during demolding and mold closing.
