The setting plate on the PP hollow plate production line is the key part of cooling and setting the plate, and the cooling effect of the setting plate directly affects the production efficiency of the production line. The function of the setting plate of the PP hollow plate is to maintain the shape of the PP hollow plate just extruded from the mold and promote its cooling and setting. The setting plate includes an upper setting plate and a lower setting plate. The working surface of the setting plate is distributed with a vacuum groove connected to a negative pressure source. A cooling water pipeline is arranged in the entity of the setting plate.

In the description of the utility model, the meaning of ''a plurality of'' is two or more, unless otherwise specified.

[0020] As Figure 1 shown, the utility model relates to a kind of vacuum shaping waterway, including plate body 1 and the water inlet pipe 2 and water outlet pipe 3 located at the both sides of plate body 1, plate body 1 is the shaping plate of PP hollow plate, for assisting the description of the following corrugated waterway 7 and cooling water hole 8, plate body 1 is connected with the shaping table of prior art, thus it is no longer described in detail.In the embodiment, plate body 1 is lower shaping plate, water inlet pipe 2 and water outlet pipe 3 are connected to external water circulating equipment, for providing cooling circulating water to the plate material of the PP hollow plate to be cooled on the upper surface of plate body 1. Plate body 1 is equipped with several vacuum suction ports 4 connected to external vacuum equipment, and the vacuum suction ports 4 are used for vacuum adsorption to the plate material on the upper surface of plate body 1.

[0021] As Figure 2 and Figure 3 shown, in a preferred embodiment, one side of the inner cavity of plate body 1 is provided with a water inlet main pipeline 5 connected to the water inlet pipe 2, and the water inlet main pipeline 5 extends from one side to the other side along the horizontal direction of the inner cavity of plate body 1. The other side of the inner cavity of plate body 1 away from the water inlet main pipeline 5 is provided with a water outlet main pipeline 6 connected to the water outlet pipe 3, and the water outlet main pipeline 6 extends from one side to the other side along the horizontal direction of the inner cavity of plate body 1, and the water outlet main pipeline 6 is arranged opposite to the water inlet main pipeline 5. A plurality of rows of evenly distributed corrugated waterways 7 are connected between the water inlet main pipeline 5 and the water outlet main pipeline 6, and the corrugated waterways 7 are provided with cooling water holes 8 with non-circular longitudinal section. The cooling water hole 8 is the longitudinal section of the corrugated waterway 7, and the length of the upper end of the cooling water hole 8 is the contact length of the corrugated waterway 7 with the upper surface of plate body 1. Cooling water enters each corrugated waterway 7 evenly from the water inlet main pipeline 5, and the corrugated waterway 7 can be used for cooling the plate material above plate body 1.

[0022] In the example of the present embodiment Figure 3 , the corrugated water channels 7 are arranged in 10 groups and evenly arranged in the horizontal direction of the inner cavity of the plate body 1. The corrugated water channels 7 can make the distribution of the cooling water in the inner cavity of the plate body 1 more uniform, and make the temperature distribution of the upper surface of the plate body 1 more uniform. In this way, the cooling temperature of the plate body 1 relative to the surface of the plate is more uniform, and the cooling and shaping effect of the plate is better.

[0023] In a preferred embodiment, the length of the longitudinal section of the cooling water hole 8 away from the plate is not greater than the length of the side close to the plate, that is, the upper end of the cooling water hole 8 of the present application is closer to the contact surface of the cooling working surface of the plate body 1 and has a larger contact area than the existing circular water hole under the same unit area. This can make the plate in the plate body cool and shape faster, allow the plate to pass through the shaping plate at a faster speed, improve the cooling efficiency of the plate, and thus improve the production capacity of the production line.

[0024] In a preferred embodiment, the cooling water hole 8 is a square water hole 801, and a support body 9 is arranged between adjacent corrugated water channels 7. The square structure of the square water hole 801 can not only increase the length and area of the contact surface of the cooling water and the cooling working surface of the plate body 1, but also the support body 9 between the two adjacent corrugated water channels 7 can effectively support the plate on the upper surface of the plate body 1, thereby ensuring the stability of the vacuum shaping.

[0025] As shown in Figure 4 , in a preferred embodiment, the cooling water hole 8 is an inverted trapezoidal water hole 803. The inverted trapezoidal structure of the inverted trapezoidal water hole 803 can also increase the length and area of the contact surface of the cooling water and the cooling working surface of the plate body 1, and the support body 9 between the two adjacent corrugated water channels 7 can also effectively support the plate on the upper surface of the plate body 1. At the same time, under the same unit area, the inverted trapezoidal water hole 803 has a larger length and area of the contact surface of the upper end and the cooling working surface of the plate body 1 than the square water hole 801.

[0026] As shown in Figure 5 , in a preferred embodiment, the cooling water hole 8 is an inverted triangular water hole 802. The inverted triangular water hole 802 is not limited to the size shown in the figure, and the area of the longitudinal section thereof can be customized and designed according to the cooling requirements of the PP hollow plate. It should be understood that the inverted triangular structure of the inverted triangular water hole 802 can make the length and area of the contact surface of the inverted triangular water hole 802 and the cooling working surface of the plate body 1 larger under the same area, thereby further improving the cooling effect and efficiency of the plate body 1 on the plate.

[0027] The preferred specific embodiments and examples of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments and examples, and various changes or equivalent replacements can be made within the knowledge range possessed by the person skilled in the art without departing from the concept of the utility model, therefore, the utility model is not limited by the specific embodiments disclosed herein, and all the embodiments falling within the scope of the claims of the application belong to the range protected by the utility model.
