Description

Technical Field

[0001] The utility model belongs to the technical field of vulcanization equipment, in particular to a silicone vulcanizer. Background Art

[0002] Vulcanization, also known as cross-linking and aging, is the process of adding cross-linking agents such as vulcanizers and accelerators to rubber to transform linear macromolecules into three-dimensional network structures under certain temperature and pressure conditions. Since sulfur was first used to achieve cross-linking of natural rubber, it is called vulcanization. The existing vulcanization equipment mainly includes flat plate vulcanizers, traditional round mold cylinder vulcanizers, new round mold vulcanizers, drum vulcanizers and other equipment; flat plate vulcanizers and traditional round mold cylinder vulcanizers are currently mainly used in my country. Vulcanizer is a machine that vulcanizes various rubber and plastic products. It has functions such as timed mold locking, automatic pressure replenishment, automatic temperature control, automatic timing, and time alarm. Vulcanizers are divided into three forms: electric heating, steam heating, and thermal oil heating.

[0003] In contrast, the Chinese patent with announcement number CN210758709U discloses a silicone vulcanizing machine, which includes a frame, on which an upper pressure plate and a lower pressure plate are respectively provided, and a first hydraulic cylinder for driving the lower pressure plate to move in a vertical direction is also provided on the frame below the lower pressure plate, an extension frame is provided on the frame, a material receiving plate is provided between the extension frame and the frame, a second hydraulic cylinder for pushing the material receiving plate to move in a horizontal direction is provided on the extension frame, and a material receiving box is provided at the end of the frame opposite to the extension frame; the material receiving plate is located between the upper pressure plate and the lower pressure plate and its height matches the spacing between the upper pressure plate and the lower pressure plate.
