Description

Technical Field

[0001] The utility model relates to the technical field of rail transit turnout area pads, in particular to a vertical casting mold used for rail transit turnout area pads. Background Art

[0002] Our company previously used horizontal molds. During the pouring and stirring process of the polyurethane material, air was easily mixed into the raw materials, resulting in obvious pores on the surface of the molded product.

[0003] However, in the existing technology, it is found that there are at least the following technical problems: polyurethane materials are easily mixed with air and produce bubbles during the molding process. If the clamping force of the template is insufficient, bubbles will appear between the molded pads, greatly reducing the cushioning effect of the pads and making them less practical. For this reason, we propose a vertical casting mold for rail transit switch area pads. Utility Model Content
