Utility model content
The defect existing for overcoming prior art, technical problem to be solved in the utility model is to provide that a kind of volume is little, cost is low, production efficiency is high, can produce the mould of multiple special-shaped teeth cavity pipe.
For addressing the above problem, the utility model provides a kind of teeth cavity pipe mold, comprise successively connected spreader external mold, die body, mouthful mould, and the internal layer extruder head being connected with spreader external mold, the outer extruder head that is connected with die body, in described spreader external mold, spreader is installed, middle level mandrel holder is installed in described die body, in described mouthful of mould, middle level plug is installed, in the mandrel holder of described middle level, internal layer mandrel holder is installed; Described middle level plug and described middle level mandrel holder are tightly connected, and described internal layer mandrel holder and described spreader are tightly connected.
Further, described middle level plug has with in the mandrel holder of described middle level the hole being communicated with.
Further, described spreader external mold is provided with internal layer eccentric adjusting screw.
Further, described die body is provided with outer eccentric adjusting screw.
Further, one end of described die body is connected with flange.
Compared with prior art, the teeth cavity pipe mold that the utility model provides adopts spreader and internal layer mandrel holder, middle level mandrel holder and middle level plug split design, dwindled mould volume, and can utilize difform internal layer mandrel holder to make multiple special-shaped teeth cavity pipe, in addition, because middle level plug has with in the mandrel holder of middle level the hole being communicated with, on the teeth cavity tube wall of making, with aperture, be convenient to wear operation optical fiber.Teeth cavity pipe die of the present utility model has the advantages that volume is little, cost is low, and can utilize the difform internal layer mandrel holder of replacing to produce multiple special-shaped teeth cavity pipe, and mould is applied widely.
