Description

Technical Field

[0001] The utility model relates to the technical field of hot-pressing processing of rubber water-stops, in particular to hot-pressing molding equipment for rubber water-stops with a positioning structure. Background Art

[0002] Rubber waterstop is mainly used in foundation engineering where it is placed in construction joints and deformation joints during concrete pouring and becomes one with the concrete structure. During the processing of rubber waterstop, it is necessary to use a mold for hot pressing.

[0003] According to the description in a molding die for producing rubber waterstop disclosed on the patent website (authorization announcement number: CN217803295 U), "the utility model discloses a molding die for producing rubber waterstop, including a fixed die and a hot pressing die. The fixed die is fixedly connected to the bottom of the processing groove of the equipment frame, and the hot pressing die is movably connected in the processing groove of the equipment frame and is located directly above the fixed die. A calibration plate is movably connected in the processing groove and at a position corresponding to the top of the fixed die. A linkage mechanism is provided in the processing groove and between the hot pressing die and the calibration plate. The beneficial effect of the utility model is that when the rubber waterstop is extended into the processing groove for hot pressing molding, the downward movement of the hot pressing die and the transmission of the connecting rotating rod and the sliding plate can make the calibration plate slide to the closer side, thereby realizing the position calibration of the waterstop and ensuring that no position deviation occurs during hot pressing molding."
