Channel converter

Abstract

The invention discloses a channel converter. The channel converter is applied to a channel of a mould. The mould comprises an upper fixing plate, a stripping plate, a female mould plate, a female mould core, a male mould core, a male mould plate, an upper ejector plate, a lower ejector plate and a lower fixing plate. The channel converter comprises a plurality of channel inserts which are rotatably arranged in the male mould core of the mould, a rotating groove, a first groove and a fastener, wherein the channel inserts are cylindrical bodies; the rotating groove is formed in the end in the axial direction of the channel inserts; the first groove is formed in the other ends of the channel inserts and provided with a second groove in the perpendicular direction of the first groove, and thesecond groove is provided with a bottom surface and two side surfaces connected with the bottom surface; and the fastener is movably fixed to one sides of the channel inserts, and one end of the fastener is fixed in the female mould plate. According to the channel converter, the channel inserts are rotated by a certain angle, so that the flow direction of plastic materials are cut off or changed,and a designated mold cavity is filled with the plastic materials, so that a plurality of products are produced in the same set of moulds.

Description

【Technical field】 [0001] The invention relates to a mold mechanism, in particular to a flow channel converter applied in a mold. 【Background technique】 [0002] see figure 1 , figure 1 A schematic structural view of a three-plate mold with a throttle valve is shown. The three-plate mold includes an upper fixing plate 101, a stripping plate 102, a female template 103, a female mold core 104, a male mold core 105, a male template 106, an upper ejector plate 107, a lower ejector plate 108 and a lower fixed plate 109, A throttling valve 110 is provided in the master template 103 . When the above-mentioned three-plate mold is producing plastic products, the flow path can be changed through the throttle valve 110 arranged in the mother template 103, and different products can be molded at the same time. [0003] However, sometimes because the throttling height of the throttling valve 110 is not adjusted properly, the throttle cannot be completely throttled, which will lead to ...
