[0026] See also Figure 1-4 , the utility model provides a technical solution:

[0027] A seat sponge forming mold includes a lower mold 1, the upper end of the lower mold 1 is sleeved with an upper mold 2, a feed pipe 3 is fixedly connected to the middle of the upper end of the upper mold 2, and a sealing block 4 is inserted and connected to the upper end of the feed pipe 3. The upper front end of the lower mold 1 and the lower front end of the upper mold 2 are both fixedly connected to a No. 1 support block 5, and the upper ends of the two No. 1 support blocks 5 are commonly inserted and connected to a fixing screw 6. The lower rear end of the lower mold 1 is fixedly connected to two No. 2 support blocks 7, and the upper ends of the two No. 2 support blocks 7 are fixedly connected to support rods 8.

[0028] In this embodiment, the four corners of the upper end of the lower mold 1 are fixedly connected with insertion rods 9, and the left and right ends of the lower mold 1 and the upper mold 2 are interspersed with two limit rods 10, the left ends of the two limit rods 10 on the left of the two groups and the right ends of the two limit rods 10 on the right of the two groups are fixedly connected with support plates 11, and the opposite ends of the two horizontal support plates 11 are interspersed with adjusting screws 12, the two limit rods 10 on the left of the two groups are located at one end inside the lower mold 1 and the upper mold 2 and the two limit rods 10 on the right of the two groups are located at one end inside the lower mold 1 and the upper mold 2 and are fixedly connected with push plates 13; the two upper adjusting screws 12 respectively pass through the two support plates 11 and are interspersed with the lower mold 1, and the two lower adjusting screws 12 respectively pass through the two support plates 11 and are interspersed with the upper mold 2.

[0029] Through the above scheme: the four insertion rods 9 are all connected with the upper mold 2 through insertion, which can strengthen the connection between the upper mold 2 and the lower mold 1. By synchronously rotating the two sets of horizontal adjustment screws 12, the positions of the two sets of horizontal support plates 11 can be adjusted, thereby adjusting the distance between the two sets of horizontal push plates 13, which facilitates the lower mold 1 and the upper mold 2 to jointly carry out the seat sponge molding process of different lengths, thereby improving flexibility.

[0030] In this embodiment, the upper mold 2 includes an upper frame 21, a feeding port 22 is opened through the upper end of the upper frame 21, and a connecting groove 23 and two limiting holes 24 are opened at both ends of the upper frame 21. The connecting groove 23 on the left is located between the two limiting holes 24 on the left, and the connecting groove 23 on the right is located between the two limiting holes 24 on the right. Two connecting blocks 25 are fixedly connected to the lower part of the rear end of the upper frame 21, and the upper frame 21 is fixedly connected to the No. 1 support block 5 on the upper part; the two connecting blocks 25 are respectively connected to the two support rods 8; the two limiting rods 10 on the left are respectively inserted and connected with the two limiting holes 24 on the left, and the two limiting rods 10 on the right are respectively inserted and connected with the two limiting holes 24 on the right.

[0031] Through the above scheme: the two connecting blocks 25 are respectively connected to the two support rods 8, which can facilitate the height adjustment process of the upper mold 2, and the feeding port 22 is fixedly connected with the feeding pipe 3, which can facilitate the feeding process in the lower mold 1 and the upper mold 2.

[0032] It should be noted that the present invention is a seat sponge forming mold. During use, the two connecting blocks 25 on the upper mold 2 are respectively sleeved with the two support rods 8, and the upper mold 2 is sleeved with the four insertion rods 9, and then the two No. 1 support blocks 5 are connected together by fixing the screw 6, so as to fix the connection between the lower mold 1 and the upper mold 2, thereby forming a closed molding space. Through the above-mentioned fixing method, the upper and lower parts of the mold are firmly connected together, which effectively improves the stability of the mold during operation and prevents the mold from being dislocated or deformed due to vibration or external force. By rotating the two sets of two horizontal adjusting screws 12, the distance between the push plates 13 can be changed by adjusting the rotation angle of the screws. This step is to ensure that the end faces of the two longitudinal push plates 13 are flush, so as to adapt to different For the molding requirements of seat sponges of the same length, after the adjustment is completed, the push plate 13 will be located at the predetermined molding position, ready for the subsequent sponge raw material injection and molding process, so that the lower mold 1 and the upper mold 2 can jointly carry out the molding process of seat sponges of different lengths. The sponge raw materials (such as polyether, isocyanate, etc.) are transported to the molding cavity of the mold through the feeding pipe 3. These raw materials undergo a chemical reaction (such as polyurethane foaming reaction) in the mold to form a seat sponge. After the mold is closed and the raw materials are injected, the raw materials react chemically in the mold and produce a large amount of gas (such as carbon dioxide), causing the raw materials to expand and form a seat sponge with a porous structure. In this process, the shape and size of the mold determine the shape and size of the final product, and the connection between the lower mold 1 and the upper mold 2 is convenient for installation and disassembly, which facilitates the removal of the molded seat sponge.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
