A new type of anti-pollution automobile mold

Abstract

The invention discloses a novel antifouling automobile mould, which comprises a movable mold, a fixed mold, a liquid discharge mechanism and a liquid blocking and exhaust mechanism. The movable mold and the fixed mold are respectively provided with a movable mold core and a static mold core, and the liquid discharge mechanism includes Liquid drainage tank, one end of the liquid drainage tank is connected with the mold cavity, and the other end is connected with a liquid discharge pipe, and the bottom of the liquid discharge pipe is provided with a liquid collection pool; the liquid blocking and exhausting mechanism includes a ring plate, a pulley, a chute, a ring There are air holes in the middle of the plate, and a baffle is provided on the inner side of the annular plate obliquely above the air holes. The annular plate includes a lower ring leaf and an upper ring leaf. There are at least two sliding columns on the upper surface of the lower ring leaf. The surface is provided with a track, the lower end of the lower ring is provided with a wheel groove, and a pulley is arranged in the wheel groove; the lower end of the movable mold core is provided with a ring groove at the corresponding position of the ring plate. The invention can isolate excess metal liquid from the movable mold core and the static mold core, can separate the gas-liquid mixture, and can also avoid secondary pollution caused by the flow of metal liquid from the air hole due to the setting of the air hole.

Description

technical field [0001] The invention belongs to the technical field of automobile moulds, in particular to a novel antifouling automobile mould. Background technique [0002] As we all know, an automobile mold is a special mold used to produce auto parts, which is widely used in automobile production; the existing automobile molds usually include a movable mold and a fixed mold, and the movable mold and the fixed mold are respectively equipped with a movable mold core. And the fixed mold core, the movable mold core and the fixed mold core are plugged and matched with each other to form a mold cavity. During use, the movable mold core moves relatively to the fixed mold core, and the excess melt is discharged after extrusion to cool to form auto parts. However, the inventors have found that during the extrusion process, due to the discharge of excess gas, the excess melt and gas are discharged outwards in the form of jets, which is not only difficult to collect and reuse, but ...

[0002] As we all know, an automobile mold is a special mold used to produce auto parts, which is widely used in automobile production; the existing automobile molds usually include a movable mold and a fixed mold, and the movable mold and the fixed mold are respectively equipped with a movable mold core. And the fixed mold core, the movable mold core and the fixed mold core are plugged and matched with each other to form a mold cavity. During use, the movable mold core moves relatively to the fixed mold core, and the excess melt is discharged after extrusion to cool to form auto parts. However, the inventors have found that during the extrusion process, due to the discharge of excess gas, the excess melt and gas are discharged outwards in the form of jets, which is not only difficult to collect and reuse, but also the ejected gas-liquid mixture It is also easy to cause pollution to the equipment

[0003] The automotive molds in the prior art generally exist during the pressing process, and the excess metal liquid mixed with gas is sprayed anywhere on the upper and lower movable fixed mold cores, so that workers need to scrub frequently to remove the metal solution and the metal slag after the metal solution condenses, seriously Reduce production efficiency, increase labor intensity of workers, and cause serious waste of molten metal, increasing costs

The anti-fouling automobile molds in the prior art are inconvenient to discharge gas. During the pressing down process of the movable mold core, due to the poor gas discharge, the die-cast automobile mold is mixed with gas, which makes the mechanical strength of the final molded automobile mould. The performance is severely degraded; on the other hand, the excess molten metal is not effectively isolated, and the isolation is not sufficient, so there will be pollution to the fixed and movable cores
