As a preferable scheme, the top of the flow regulating rod is provided with a threaded hole along the axial direction.
As a preferred scheme, an upper die top roller is movably arranged in the top plate and connected with an upper die top plate positioned below the top plate, and a plurality of vertical upper ejector pins for die sinking and pushing are arranged on the upper die top plate.
As a preferable scheme, a cooling water channel is arranged in the upper template; and a cooling water channel is arranged in the lower template.
The invention has the beneficial effects that: this flow control structure for injection mold is through setting up a plurality ofly on last mould and each mouthful matched with flow control pole of moulding plastics, the upper and lower position of flow control pole in last mould is adjustable through increasing and decreasing gasket, in flow control pole's bottom stretched into the mouth of moulding plastics, adjust the feed through adjusting corresponding to the flow control pole height to the die cavity of different positions, thereby play the effect of balanced injection pressure and velocity of flow, so that the pressure of moulding plastics is unanimous in the die cavity of each position, thereby ensure the finished product quality. And need not take apart the mould during regulation, only need loosen headless screw, increase and decrease the gasket according to the condition and realize adjusting, very convenient and fast.
Because the top of the flow adjusting rod is provided with the threaded hole along the axial direction, when the flow adjusting rod is taken out, only the headless screw is taken out, then the bolt is screwed into the threaded hole, and then the flow adjusting rod is taken out through the bolt.
Because the activity is equipped with the mould knock-out pin in the roof, goes up the mould knock-out pin and is connected with the last mould roof that is located the roof below, is equipped with a plurality of vertical die sinking on the last mould roof and pushes away and use last thimble, has made things convenient for the drawing of patterns of work piece, and can steadily deviate from the work piece, and the atress damages when avoiding the work piece drawing of patterns.
Because the upper template is provided with a cooling water channel; the lower template is provided with a cooling water channel, so that the injection molding piece can be rapidly cooled and molded, and the molding quality of the workpiece is ensured.
