Description

Technical Field

[0001] The utility model relates to the technical field of a rotary glass bead automatic press machine, in particular to a multiple demoulding structure used for a rotary glass bead automatic press machine. Background Art

[0002] Glass beads, especially crystal glass beads, are widely used in the jewelry industry as jewelry accessories. Glass beads have different shapes and are provided with through holes for threading ropes. At present, glass beads are formed by manual pressing machines, which are generally composed of molds, foot-operated discharging mechanisms and manual small punches. The glass is heated and softened in a heating furnace through a clamp, and the soft and hot glass rod material is placed in the lower mold cavity of the mold for molding; in existing glass bead automatic pressing machines, most of them are single-time demolding, which easily causes incomplete demolding, and then causes secondary extrusion to damage the mold. Utility Model Content

[0003] In order to solve the above technical problems, the technical solution provided by the utility model is: a multiple demolding structure for a rotary glass bead automatic pressing machine, including a relatively arranged gear plate positioning structure, a plurality of model columns are circumferentially plugged into the gear plate positioning structure, and a rotating guide track group, an extrusion bearing structure and a reciprocating demolding guide track group are arranged at intervals on the outer circumference of the gear plate positioning structure, so that when the model column rotates with the gear plate positioning structure, it passes through the rotating guide track group and then the extrusion bearing structure, so that the relatively arranged model columns move relative to each other and complete product extrusion, and when passing through the reciprocating demolding guide track group, it moves horizontally repeatedly to demold the product between the relatively arranged model columns.

[0004] The advantages of the utility model compared with the prior art are: the utility model can guide the rotation of the model column by arranging a rotating guide track group, can make the model columns move relative to each other to extrude the raw materials by arranging an extrusion bearing structure, and can make the model column reciprocate multiple times by arranging a reciprocating demoulding guide track group, so that the finished product formed therein can be demoulded from the model under the action of the ejector pin, thereby completing the demoulding operation.
