As shown in fig. 1 and 2, in one embodiment, a cooling molding apparatus includes: connect material body 100, driving piece and spray mechanism 200, connect material body 100 to be equipped with the feed portion 110 that is used for plastics wire rod 10 to get into, connect material body 100 to be equipped with the ejection of compact portion 120 that is used for plastics wire rod 10 to derive, the driving piece is used for driving plastics wire rod 10 and removes, it is equipped with condenser tube 210 that is used for carrying external water source to spray mechanism 200, the end orientation that sprays mechanism 200 is located connect the inside plastics wire rod 10 of material body 100, connect to be equipped with on the material body 100 with spray mechanism 200 and the corresponding water storage portion 130 of plastics wire rod 10.

When the cooling forming device is used, the feeding part 110 of the material receiving body 100 is aligned with the extrusion port of the wire extrusion device, so that the extruded wire can enter the material receiving body 100 timely and accurately. Then, the spraying mechanism 200 sprays the cooling water delivered to the spraying end by using the cooling water pipe 210, and at this time, the sprayed cooling water is sprinkled on the plastic wire 10, thereby cooling the plastic wire 10. Meanwhile, the water storage part 130 recovers the sprayed water. The above embodiment ensures that the water source (cooling water) sprayed by the spraying mechanism 200 and the water source (water received by the water storage part 130) for cooling the plastic wire 10 are independent from each other, that is, the cooling water sprayed by the spraying mechanism 200 each time does not increase the water temperature due to the cooling contact with the plastic wire 10. Therefore, the cooling molding device ensures that the cooling water for cooling the plastic wire 10 does not increase the water temperature of the cooling water due to the cooling contact with the plastic wire 10, thereby improving the cooling of the plastic wire 10.

In one embodiment, the drive member is a servo motor or a variable speed motor. The driving member can drive the plastic wire 10 to move in a corresponding process by means of a roller or a pulley, for example, the plastic wire 10 moves inside the material receiving body 100 by using the power of the driving member. Further, according to the actual processing situation, in order to avoid the influence of the driving member on the cooling of the plastic wire 10 inside the material receiving body 100, the driving member and the material receiving body 100 may be arranged relatively independently. Further, the feeding portion 110 of the receiving body 100 corresponds to the discharging portion 120 of the preceding device (e.g., a plastic extruder), so that the plastic wire 10 can more easily enter the receiving body 100 for cooling.

As shown in fig. 1 and 2, in an embodiment, the spray mechanism 200 includes a water conduit 220 and a spray pipe 230, the material receiving body 100 is provided with a mounting hole, one end of the water conduit 220 is connected to the cooling water pipe 210 through the mounting hole, the other end of the water conduit 220 is communicated with the spray pipe 230, the spray pipe 230 is located inside the material receiving body 100, and the spray pipe 230 is provided with a plurality of spray ports 231 for water outlet. Specifically, the cooling water pipe 210 is a metal pipe or a plastic pipe, in this embodiment, the cooling water pipe 210 is a metal pipe, that is, when the water source flows inside the cooling water pipe 210, the cooling water pipe 210 can absorb heat from the water source, so that the temperature of the water source sprayed by the spraying mechanism 200 is lower, and a better cooling effect is achieved on the plastic wire 10. Further, in order to ensure that the spray pipe 230 is located at the optimal spraying position inside the material receiving body 100, a mounting hole is formed in the material receiving body 100, and one end of the water guide pipe 220 is connected to the cooling water pipe 210 through the mounting hole. Namely, the installation position of the shower pipe 230 is determined, and then the water guide pipe 220 is used for transition, so that the shower pipe 230 is communicated with the cooling water pipe 210. Further, in the present embodiment, the shower opening 231 is directly opened in the shower pipe 230, that is, the water pressure inside the shower pipe 230 is utilized to directly spray the water from the shower opening 231. This is only one of the embodiments, for example: in order to further increase the spraying range of the spraying port 231, a shower sheet can be additionally arranged at the spraying port 231 (i.e. a plurality of capillary ports are formed on the surface of the sheet body, and the forming positions of the plurality of capillary ports on the surface of the sheet body can be determined according to the actual spraying requirements). Alternatively, a rotatable shower head may be installed at the shower port 231, and the spraying range of the shower pipe 230 is increased by the rotation of the shower head.

In one embodiment, the cooling water pipe 210 and the water guiding pipe 220 may be integrally formed, that is, one end of the cooling water pipe 210 is used for receiving a water source, and the other end of the cooling water pipe 210 is inserted into the material receiving body 100 through the mounting hole and connected to the spraying pipe 230. The above embodiment can improve the sealing performance of the shower mechanism 200.

Further, the plastic wire 10 passes through the water storage part 130 when moving inside the material receiving body 100, and considering that when the shower pipe 230 sprays, the amount of water source sprayed on the plastic wire 10 by the water source is limited or the contact time between the water source and the plastic wire 10 is limited. In order to further improve the cooling effect of the spraying mechanism 200 on the plastic wire 10, one side of the water storage part 130 is open, that is, the water source sprayed by the spraying mechanism 200 enters the water storage part 130 through the open to be collected, and meanwhile, the plastic wire 10 passes through the inner space of the water storage part 130, so that the water source in the water storage part 130 can cool the plastic wire 10 again. Along with the water source of the water storage part 130 is collected continuously, the water source can overflow from the opening of the water storage part 130 continuously, thereby ensuring that the water source in the water storage part 130 can not affect the cooling of the plastic wire 10 due to the rising of the water temperature. In addition, the sprayed water may collide with the water source inside the water storage part 130 when it is scattered into the water storage part 130, thereby accelerating the heat dissipation of the water source.

More specifically, the spraying pipe 230 and the water storage portion 130 both extend from the feeding portion 110 of the material receiving body 100 to the discharging portion 120 of the material receiving body 100, and the above embodiment ensures that the plastic wires 10 located in each region of the material receiving body 100 can be effectively cooled.

Specifically, the first spraying baffle 131 and the water receiving plate 133 form an obtuse angle, and the second spraying baffle 132 and the water receiving plate 133 also form an obtuse angle. That is, the water source sprayed on the first or second spray baffles 131 or 132 can flow toward the water receiving plate 133 by its own weight. More specifically, one end of the first spraying baffle 131 protrudes out of the spraying pipe 230, that is, an included angle between the first spraying baffle 131 and the second spraying baffle 132 and the water receiving plate 133 is determined according to an actual spraying range of the spraying pipe 230, so that it is effectively ensured that a water source sprayed by the spraying pipe 230 can fall into the water storage part 130 for collection.

The above embodiment realizes the recycling of the water source on one hand, and also avoids the higher water temperature of the water source on the other hand.

In one embodiment, considering that there is not enough time for the water source inside the water storage tank to dissipate heat, the cooling water pipe 210 may further communicate with an external water supply pipe, that is, when the water source inside the water storage tank has a high temperature, the external water supply pipe is directly used to introduce the cooling water into the cooling water pipe 210 for cooling.

The cooling forming device ensures that a water source (cooling water) sprayed by the spraying mechanism 200 and a water source (water source received by the water storage tank) for cooling the plastic wire 10 are mutually independent, namely ensures that the cooling water sprayed by the spraying mechanism 200 every time can not cause the temperature rise due to the cooling contact with the plastic wire 10. Therefore, the cooling forming device ensures that the cooling water for cooling the plastic wire 10 does not increase the water temperature of the cooling water due to the cooling contact with the plastic wire 10, thereby effectively improving the cooling of the plastic wire 10.

Further, considering that the airflow blown from the blow-drying assembly may blow toward the water storage portion 130, at this time, the water source may be scattered in the water storage portion 130 or collected toward a certain portion of the water storage portion 130, so that the water storage portion 130 may not effectively cool the wire. Therefore, in the present embodiment, the installation position of the blow-drying mechanism 400 on the cooling and forming device is different in height from the installation position of the water storage portion 130 on the cold penguin forming device. I.e., to prevent a large amount of air from the blow-drying mechanism 400 from being blown toward the water storage part 130.
