Description

Mold for preparing rubber covered wheel and forming device

Technical Field

The utility model relates to a rubber coating wheel technical field, specific is a mould and forming device for preparing rubber coating wheel.

Background

The rubber coating wheel shown in fig. 1 comprises a hub 11 and a buffer rubber 12 coated on the outer wall of the hub 11, wherein two ends of the outer wall of the buffer rubber 12 are respectively chamfered, so that two ends of the outer wall of the buffer rubber 12 are respectively provided with an inclined surface.

At present, most of molds for preparing the rubber covered wheel are processed by steel, the molds are cylindrical, and a cavity is arranged in the cylindrical molds and penetrates through one end of the molds and does not penetrate through the other end of the molds along the axis direction. That is, the lower end of the mold is closed and the upper end is open. When the rubber-coated wheel needs to be prepared, the wheel hub is firstly placed in a mold for positioning, then liquid rubber is injected from the open upper end of the mold, and the liquid rubber flows from the upper end to the lower end of the mold until being solidified to form solid buffer rubber 12 coated outside the wheel hub 11. The mould of this structure is simple, the simple operation, but also has following some problems:

1. because the upper end of the mold is in an open manner, the shape of the upper half portion of the cushion gum 12 in the molding process is free from mold constraint (that is, the inclined surface at the end of the cushion gum 12 corresponding to the upper end of the mold cannot be molded by the mold), the shape and size requirements cannot be met at one time, and the shape and size of the upper half portion need to be met by secondary processing.

2. After the liquid glue is solidified in the mould, the liquid glue is firmly bonded with the mould and is not easy to take out a product. Therefore, before each glue pouring, a release agent needs to be sprayed on the surface of the mold to ensure that the product is completely separated from the mold, and each release agent spraying leads to complex operation and high cost.

3. Due to the cylindrical design, the mold occupies a large area, and the glue filling is horizontally placed during operation, so that the occupied space is large.

4. The mold made of steel has larger mass.
