Description

Technical Field

[0001] The utility model relates to the field of silica gel foam production, in particular to a hot pressing splicing machine. Background Art

[0002] Silicone foam is a special material. It is a porous, low-density, compressible polymer elastomer made by evenly mixing raw materials such as silicone rubber, fillers, vulcanization accelerators, and foaming glue, and then undergoing a special process under high pressure and high temperature. Silicone foam is a material with a variety of application scenarios. It combines a series of characteristics such as elasticity, light weight, fast pressure-sensitive fixation, easy use, easy bending, ultra-thin volume, and reliable performance. In the production and processing of silicone foam, two or more silicone foams need to be spliced ​​and formed according to actual use requirements.

[0003] After searching, Chinese patent announcement number: CN218876244U discloses a foam silicone plate hot pressing molding machine. By adjusting two motors, the two motors indirectly control the two connecting strips to move forward or backward, and then adjust the position of the lower die, thereby reducing the problem of burns to the staff's arms caused by the high temperature generated by the upper die when the staff takes the foam silicone plate. At the same time, when the staff takes out the foam silicone plate, the upper die will not suddenly move, causing damage to the staff's arms.

[0004] In the above technical solution, a motor is used to control the position of the lower die to avoid the risk of burns to the staff's arms. However, when multiple groups of silicone foam need to be spliced ​​and formed during hot pressing, it is difficult to ensure the stability of the multiple groups of silicone foam placed on the surface of the lower die. The offset causes the splicing parts to be unable to be in a fitting state, which reduces the efficiency and effect of hot pressing splicing. Therefore, a hot pressing splicing machine is proposed to solve the above problems. Utility Model Content

[0039] Working principle: When multiple groups of silicone foam need to be spliced, first determine the size of the silicone foam and then start the motor 701. The motor 701 drives the bidirectional screw rod 702 to rotate, so that the moving block 703 drives the two groups of positioning frames 705 to move closer or farther away from each other, and insert the multiple groups of silicone foam into the through grooves of the two groups of positioning frames 705 in turn. The elastic force of the spring 708 will allow the pressing plate 709 to press it tightly. When the silicone foam is placed, confirm that the spliced ​​parts remain in a fitted state. When the multiple groups of silicone foam are placed according to the above steps, turn on the electric heating rods of the upper die 5 and the lower die 6. After the upper die 5 and the lower die 6 generate heat, start the hydraulic cylinder 4, and the upper die 5 will gradually descend and approach the lower die 6 to hot-press the silicone foam until the spliced ​​parts are hot-pressed and formed, and then turn off the electric heating rod. At this time, the circulating pump 712 and the air pump 713 is turned on, and the circulating pump 712 draws the coolant of the external circulating refrigeration and transmits it to the inside of the cooling pipe 711. The wind source produced by the air pump 713 is converted into relatively low-temperature cold air after passing through the cooling pipe 711, and then sprayed out through the through hole 710 to contact the silicone foam to cool the spliced ​​parts. During the cooling process, the hydraulic cylinder 4 drives the upper pressing mold 5 to gradually rise. When the cooling is completed, the electromagnet 1 801 and the electromagnet 2 802 are energized at the same time. The mutually repelling magnetism of the two will cause the left set of pressing plates 709 to gradually move upward, thereby reducing the pressing force on the silicone foam. Finally, the operator holds the auxiliary rod 804 with one hand to lift the right side pressing plate 709 upward, and pulls the silicone foam out of the through groove in turn with the other hand, completing the discharge of hot pressing splicing, improving the efficiency of hot pressing of silicone foam and the stability of hot pressing splicing.
