Outlet water collecting device for extrusion die for specially-shaped plastic materials

Abstract

An outlet water collecting device for an extrusion die for specially-shaped plastic materials comprises a bottom plate and a die plate installed on the bottom plate, wherein a plurality of water outlet nozzles are arranged on the die plate, each water outlet nozzle is connected with a water outlet pipe, a plurality of water inlets are formed in side walls of the bottom plate, the tail end of each water outlet pipe is connected with one water inlet, water in the water outlet pipes flows through the water inlets and then is collected in a water collecting cavity formed in the bottom plate, the water collecting cavity is also communicated with a plurality of shunting holes perpendicular to the water inlets, and the water in the water collecting cavity flows out of the plurality of shunting holes. With the adoption of the outlet water collecting device, the phenomenon that high-pressure water splashes around can be effectively avoided, the production safety can be guaranteed, the device is arranged by the aid of the structure of the die, and the cost is effectively reduced.

Description

technical field [0001] The invention relates to the field of moulds, in particular to a water collecting device for extruding molds of plastic profiled materials. Background technique [0002] There are many mold outlet pipes on the extrusion mold of plastic profiles. When the mold outlet pipes are in a free state, the positions are randomly placed. Generally, more than 2 kg of high-pressure cooling water flows out of the water pipes and splashes everywhere, making the ground wet and slippery. Operators are easy to slip; One thing is that the equipment is prone to rust after being wet by water, causing the equipment to malfunction or even be damaged. When the mold is opened in the production state, the water pipe is driven to shake, and the water will directly rush to the operator to affect the work; even rush to the die head to cool the die head locally, resulting in uneven discharge and a large amount of waste. Some molds are additionally installed with a water collection...

Problems solved by technology

[0002] There are many mold outlet pipes on the extrusion mold of plastic profiles. When the mold outlet pipes are in a free state, the positions are randomly placed. Generally, more than 2 kg of high-pressure cooling water flows out of the water pipes and splashes everywhere, making the ground wet and slippery. Operators are easy to slip; One thing is that the equipment is prone to rust after being wet by water, which will cause the equipment to malfunction or even be damaged.

When the mold is opened in the production state, the water pipe is driven to shake, and the water will directly rush to the operator to affect the work; even rush to the die head to cool down the die head locally, resulting in uneven discharge and a large amount of waste.

Some molds are additionally installed with a water collection device to collect the water together, and the high-pressure cooling water is concentrated in the device for buffering and then flows out. However, due to the addition of new parts, the cost is increased, the mold is more complicated, and the processing and manufacturing and use are increased. and maintenance difficulty
