Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical technology, specifically to a seat molding mold insert with an internal cooling water channel. Background Technology
[0002] Seat molding is mostly completed through injection molding. Seats include backrests and seats. Since the backrest of the seat needs to be connected to the frame, chassis, gas spring, and other structures, the structure of the backrest of the seat often differs in different models of seats. Therefore, it is necessary to design matching molds for different backrest structures for production. Summary of the Invention
[0003] To overcome the shortcomings of the prior art, this utility model provides a seat molding mold insert with an internal cooling water channel.
[0004] To achieve the above objectives, a seat molding mold insert with internal cooling water channels is designed, including a molding insert, top blocks on the front and rear sides of the molding insert, a top block cylinder connected to the upper end of the top block, a notch on one side of the molding insert, a molding surface on the other side of the molding insert, and several cooling water channels inside the molding insert.
[0005] The top block has a groove on one side that mates with the top block cylinder.
[0006] The molding surface is provided with several molding grooves.
[0007] The surface of the molded insert on one side of the notch is provided with several positioning grooves.
[0008] The surface of the molded insert is provided with several through holes.
[0009] The molded insert has a guide post inside, and a guide sleeve is provided on the outside of the guide post.
[0010] The cooling water channels are arranged in both horizontal and vertical directions.
[0011] The molded insert has mounting grooves on both the front and rear sides that mate with the top block.
[0012] The molded insert has a clearance groove on one side.
[0013] Compared with existing technologies, this invention has a simple structure. By cooperating with the molding surface and external components, the required structure for the back of the chair seat is processed, and then the processed structure is cooled by a cooling water channel. Furthermore, the cooperation of the top block and the top block cylinder facilitates demolding at the contact point between the molding surface and the chair seat. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings.
[0023] like Figures 1 to 7 As shown, the molding insert 1 has top blocks 2 on the front and rear sides respectively. The top block 2 is connected to the top block cylinder 3. The molding insert 1 has a notch 1-1 on one side of the horizontal direction and a molding surface 1-2 on the other side of the horizontal direction. Several cooling water channels 1-4 are provided inside the molding insert 1.
[0024] like Figure 8 As shown, the top block 2 has a groove 2-1 on one side that cooperates with the top block cylinder 3.
[0025] The molding surface 1-2 is provided with several molding grooves 1-3. In actual use, the molding grooves 1-3 cooperate with external components to process the inverted structure required for the back of the chair seat.
[0026] The surface of the molded insert 1 on one side of the notch 1-1 is provided with several positioning grooves 1-5. In actual use, the positioning grooves 1-5 cooperate with external components to position the cooperation between other components and the molded insert 1.
[0027] The surface of the molding insert 1 is provided with several through holes 1-6, which facilitates the molding component to pass through the molding insert 1 and process the back of the chair seat to obtain the required grooves, screw holes and other structures.
[0028] The molded insert 1 has guide posts 1-8 inside, and guide sleeves are provided on the outside of the guide posts 1-8 to play a guiding role.
[0029] The cooling water channels 1-4 are arranged in both horizontal and vertical directions to ensure cooling effect from both directions.
[0030] The front and rear sides of the molded insert 1 are respectively provided with mounting grooves 1-9 that cooperate with the top block 2.
[0031] The molding insert 7 has a clearance groove 1-10 on one side. In actual use, the seat molding needs to be used in conjunction with the glue injection component. The clearance groove 1-10 plays a role in avoiding the glue injection component.
[0032] In use, the molding surface 1-2 and recess 1-1 of the molding insert 1 cooperate with other molding components to process the chair seat. When it needs to be removed after processing, the top block cylinder 3 first pushes out, and the top block 2 drives the molding insert 1 to lift the chair seat, ensuring that the molding surface and the chair seat can be demolded smoothly.
[0033] During the processing, since the cooling water channel 1-4 is located inside the molding insert 1 and close to the molding surface 1-2, the processed structure can be cooled in time, thereby ensuring the molding quality of the seat.
