Abstract

The invention discloses a throttling column mechanism, which comprises: a first through hole, which is arranged in the master template, and a second through hole is arranged along the downward direction of the first through hole; a throttling column, which is The throttling column is movably arranged in the first through hole, the lower end of the throttle column is provided with a limit block, and the limit block is movably arranged in the second through hole; the elastic element is movably arranged in the second through hole , and the elastic element is sleeved on the throttling column; a third through hole, which is arranged in the female mold core and communicates with the second through hole, along the third through hole A fourth through hole is arranged in the downward direction; a fastener is movably arranged in the third through hole, the upper end of the fastener is fixedly connected to the limit block, and the lower end of the fastener is fixed on a over the head. Using the throttling column mechanism of the present invention, the flow of the plastic material is blocked by using the throttling column, so that the plastic material is filled in the designated mold cavity, and multiple products can be produced in the same set of molds.

Description

【Technical field】 [0001] The invention relates to a mold mechanism, in particular to a throttling column mechanism 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, Wherein, a throttling valve 110 is arranged in the mother template 103 , and the throttling valve is fixed on an adjusting screw 111 . When the above-mentioned three-plate mold is producing plastic products, due to the short stroke distance between the stripping plate 102 and the mother template 103, the technician cannot make the throttle valve 110 penetrate into the flow channel 1031 inside the mold, so the mold needs to be disassembled. Adjust the adjus...
