The right end of the No. 2 top rod is provided with a runner well, which is arranged below the left end of No. 1 top rod, and the front side of the No. 1 top rod is provided with a flow channel. The runner is connected with the water inlet of the mold body, and a hot nozzle is inserted on the left side of the runner; the right side of the runner is provided with a knife edge, the knife edge is suspended in the mold body, and the upper end of the knife edge is fixed on the slider, sliding The block is slidably arranged in the groove on the left side of the mold body. The upper end of the slider is fixed on the piston rod of the oil cylinder. After the oil cylinder passes through the oil cylinder seat, it is exposed above the oil cylinder seat, and the oil cylinder seat is fixed on the upper surface of the mold body. superior.

Further, the knife edge is arranged at a reverse slope, and its left end is lower than its right end.

Further, the water inlet of the mold body is a Y-shaped water inlet.

After the above structure is adopted, the beneficial effects of the present utility model are as follows: the strong self-cutting nozzle device in the mold of the present utility model has a sliding block designed in the mold, the sliding block is controlled by an oil cylinder, and the oil cylinder is regulated by the oil pressure in the injection molding machine Therefore, the ordinary injection molding machine can also be integrally formed, and the finished product does not need to be processed twice, which saves time and labor, and also saves costs. The utility model has the advantages of simple structure, reasonable setting and low production cost.

Mold body 1, No. 1 ejector pin 2, No. 2 ejector pin 3, runner well 4, runner 5, hot nozzle 6, knife edge 7, slider 8, oil cylinder 9, oil cylinder seat 10, product 11.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings.

Referring to Fig. 1 and Fig. 2, the technical solution adopted in this specific embodiment is: it comprises a mold body 1, the inner middle end of the mold body 1 is provided with a No. 1 ejector rod 2, and the lower end of the No. There is No. 2 ejector rod 3, No. 1 ejector rod 2 and No. 2 ejector rod 3 are connected with external power, the right end of No. 2 ejector rod 3 is provided with a runner well 4, and the runner well 4 is arranged on the No. 1 ejector rod 2 Below the left end, the front side of the upper end of the No. 1 ejector rod 2 is provided with a flow channel 5, which is connected with the water inlet of the mold body 1, and a hot nozzle 6 is inserted on the left side of the flow channel 5; The right side is provided with a knife edge 7, the knife edge 7 is suspended in the mold body 1, the upper end of the knife edge 7 is fixed on the slider 8 by bolts, the slider 8 is slidably arranged in the groove on the left side of the mold body 1, and the slider 8 The upper end of the mold is welded and fixed on the piston rod of the oil cylinder 9. After the oil cylinder 9 passes through the oil cylinder seat 10, it is exposed above the oil cylinder seat 10. The oil cylinder seat 10 is fixed on the upper surface of the mold body 1 by bolts.

Further, the knife edge 7 is set at a reverse slope, and its left end is set lower than its right end, which can ensure that the nozzle is squeezed downward, and glue will not overflow to the product 11 .
