Description
Technical Field
The utility model relates to a cooling forming device, especially plastics extrusion molding section bar cooling forming device.
Background
At present, in common extrusion molding section bar production, molten plastic is extruded from a die head and then is immersed into a cooling pipe filled with cooling water for cooling and shaping. The bottom end of the cooling pipe in the cooling shaping device is connected with a water inlet pipe of cooling water, and an overflow port is arranged at the top end of the cooling pipe, so that the cooling water forms circulation, and the temperature of the cooling water is not too high. However, the cooling water in the cooling pipe in the cooling and shaping device has poor integral fluidity and the cooling effect of the section bar is poor; and most of the cooling water in the cooling pipe overflows from the overflow port without exchanging heat with the section bar, so that the consumption of the cooling water is large. Therefore, the existing plastic extrusion molding section cooling forming device has the problems of poor cooling effect and large cooling water consumption.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a plastics extrusion molding section bar cooling forming device. The utility model discloses not only can improve the cooling effect, still have the less advantage of cooling water quantity.
The technical scheme of the utility model: the plastic extrusion molding section cooling forming device comprises a hollow cooling pipe, wherein an annular connector is fixed at one end of the cooling pipe, and an annular cavity is formed in the connector; the outer wall of the connector is connected with a water inlet pipe which is communicated with the cavity; the side wall of the inner ring of the connector is provided with a plurality of water spray nozzles.
In the aforesaid plastics extrusion molding section bar cooling forming device, the other end that is connected with the connector relatively on the cooling tube is fixed with the flexibility and seals, and the middle part that the flexibility was sealed is equipped with the opening.
In the plastic extruded section cooling forming device, the top end of the cooling pipe is provided with an overflow port.
In the plastic extrusion molding section cooling forming device, all the water spray nozzles on the side wall of the inner ring of the connector are uniformly distributed in an annular shape.
In the above-described apparatus for cooling and forming a plastic extruded section, the water jet is provided toward the cooling pipe.
Compared with the prior art, the utility model improves the existing plastic extrusion molding section cooling forming device, and one end of the cooling pipe is fixed with an annular connector, one side of the inner ring part of the connector can be in threaded connection with the extrusion molding die, so that the section passes through the connector and enters the cooling pipe after being extruded from the extrusion molding die; an annular cavity is arranged in the connector, after cooling water is introduced into the connector through the water inlet pipe, the cooling water can be sprayed out from a water spraying port on the side wall of the inner ring of the connector, the flow of the cooling water around the section is fully driven, and the cooling effect of the section is improved; the cooling water sprayed from the water spray opening can fully contact with the section bar to carry out heat exchange, and the consumption of the cooling water is less. In addition, the other end of the cooling pipe, which is relatively connected with the connector, is fixed with a flexible seal, and the middle part of the flexible seal is provided with an opening for the section bar to pass through, so that the cooling pipe can be filled with cooling water after the cooling water enters the cooling pipe from the connector, the section bar can be completely immersed in the cooling water, and the cooling effect is improved; excessive cooling water after heat exchange is finished can overflow from an overflow port at the top end of the cooling pipe, so that the temperature of the cooling water in the cooling pipe is not too high; the water spray nozzles uniformly distributed in the annular shape can effectively and uniformly cool all positions of the section bar, and the cooling effect is good; and all the water spray nozzles are arranged towards the direction of the cooling pipe, so that the sprayed cooling water can further stir the cooling water in the cooling pipe, and the cooling effect is improved.

Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. The plastic extrusion molding section cooling forming device comprises a hollow cooling pipe 1 as shown in figures 1 to 4, wherein one end of the cooling pipe 1 is fixedly provided with an annular connector 2, and an annular cavity 3 is arranged in the connector 2; the outer wall of the connector 2 is connected with a water inlet pipe 4, and the water inlet pipe 4 is communicated with the cavity 3; the inner ring side wall of the connector 2 is provided with a plurality of water spray nozzles 5.
A flexible seal 6 is fixed at the other end of the cooling pipe 1 opposite to the connector 2, and an opening 7 is formed in the middle of the flexible seal 6; the top end of the cooling pipe 1 is provided with an overflow port 8; all the water spray nozzles 5 on the side wall of the inner ring of the connector 2 are uniformly distributed in a ring shape; the water spray nozzle 5 is arranged towards the cooling pipe 1.
The working principle is as follows: connecting a connector 2 with an extrusion molding die, immersing cooling water into a cavity 3 in the connector 2 from a water inlet pipe 4 on the outer wall of the connector 2, and spraying the cooling water in the cavity 3 into a cooling pipe 1 from a plurality of water spray nozzles 5 which are uniformly distributed in a ring shape on the side wall of the inner ring of the connector 2; because the other end of the cooling pipe 1 is provided with the flexible seal 6, the cooling water can fill the cooling pipe 1 until the cooling water overflows from the overflow port 8 at the top end of the cooling pipe 1.
The profile is then fed from the extrusion die into the cooling tube 1 and out through the opening 7 in the middle of the flexible seal 6; when the section passes through the position of the connector 2, cooling water sprayed from a plurality of water spray nozzles 5 which are uniformly distributed in an annular manner can drive the cooling water on the outer surface of the section to flow, so that the cooling effect of the section is improved; and the sprayed cooling water can stir the flow of the cooling water in the cooling pipe 1, so that the cooling water in the cooling pipe 1 can exchange heat with the sectional material as much as possible, and finally flows out from an overflow port 8 at the top end of the cooling pipe 1, the utilization rate of the cooling water is improved, and the consumption of the cooling water is reduced.
