Embodiment Construction

[0014] see figure 1 and figure 2 As shown, the present invention provides a V-shaped elevator handrail molding device, which includes an upper mold 10 , a lower mold 20 and a mold core 30 between the upper mold 10 and the lower mold 20 .

[0015] The mold core 30 includes a strip-shaped body 31 , a pair of primary cooling sections 32 located at longitudinal ends of the body 31 , and a secondary cooling section 33 located outside the primary cooling section 32 . Wherein, the body 31 extends longitudinally, and it is provided with a bottom surface 310, a top surface 311 and an end surface 312. The bottom surface 310 is narrower than the top surface 311, forming a roughly V-shaped structure, and the bottom surface 310 is provided with The concave hole 313 and the steel sheet 314 accommodated in the concave hole 313, the steel sheet 314 is fixed on the bottom of the body 31 by countersunk screws, and does not protrude from the concave hole 313, the setting of the steel sheet 314...

Abstract

The invention provides a V-shaped escalator hand strap mold pressing device. The V-shaped escalator hand strap mold pressing device comprises an upper mold, a lower mold and a mold core located between the upper mold and the lower mold. The mold core comprises a long strip-shaped body, a pair of primary cooling sections located at the two longitudinal ends of the body, and secondary cooling sections located on the outer sides of the primary cooling sections. A V-shaped groove is formed in the top surface of the body. Heat insulation pieces are arranged between the primary cooling sections and the body as well as between the primary cooling sections and the secondary cooling sections. Compared with the prior art, the V-shaped escalator hand strap mold pressing device has the advantages that the structure of the mold core is improved, the size of the mold pressing device is small, carrying is convenient, and the requirement for field mold pressing of V-shaped polyurethane hand straps is met; and in addition, field operation is convenient, and the working efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a V-shaped elevator handrail molding device. Background technique [0002] At present, the elevator handrail is spliced ​​and molded in the factory, and then installed on site. However, due to customer or installation and maintenance needs, it needs to be spliced ​​on site. At present, most of the existing molding devices are polyurethane C-shaped molding systems, which are mainly designed for C-shaped handrails, and there is no splicing molding device for polyurethane V-shaped handrails. Since the molded polyurethane V-shaped handrail not only meets the requirements of surface appearance and material performance, but also meets the requirements of straightness and performance, V-shaped handrail products are gradually promoted and applied. The demand is also getting stronger. Contents of the invention [0003] The technical problem solved by the present invention is to pro...
