Abstract
The utility model provides an ejector sleeve structure at top of a top roller. The ejector sleeve structure enables smooth implementation of the ejector sleeve at the hole position of the top roller; and as a result, the design cost of a mold is reduced, and the ejector sleeve structure is simple in structure and low in fabricating cost. The ejector sleeve structure comprises a front mold and a rear mold, wherein a pouring gate structure is formed at the interface at the center of the front mold and the rear mold, cavities on the two sides are communicated by virtue of the pouring gate structure, and the rear mold is supported on a plate B. The ejector sleeve structure is characterized in that a combined structure of an ejector plate and an ejector retainer plate is arranged under the plate B at an interval of a section of cavity, the lower end of the ejector retainer plate is supported on a support block on a base plate, the lower end of a material channel ejector is fastened on a central positioning cavity formed by the ejector plate and the ejector retainer plate, the lower ends of the ejector sleeves at the two sides are fastened in two side positioning cavities formed by the ejector plate and the ejector retainer plate, respectively; the material channel ejector pushes against the lower end face of the pouring gate structure, and the ejector sleeves at the two sides push against the lower end faces of the cavities at the corresponding sides, respectively.
