Description

Technical Field

[0001] This utility model belongs to the technical field of foam molding machines, specifically relating to a rapid cooling system for molds in a foam molding machine. Background Technology

[0002] In modern industrial production, foam molding machines are widely used in the production of plastic products, foam materials, and many other fields. As a key component of the foam molding machine, the temperature control of the mold during operation has a crucial impact on production efficiency and product quality. Traditional mold cooling methods often rely on airflow to remove heat from the mold surface. This typically involves using fans or blowers to blow cool air onto the mold to achieve heat exchange. However, air cooling is relatively inefficient because air has a low specific heat capacity, requiring a large airflow to remove the same amount of heat. In large-scale production or situations requiring rapid cooling, air cooling cannot meet the demand for rapid temperature reduction. Utility Model Content

[0011] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model sets up a water tank in the cooling station. When the mold needs to be cooled, the mold is transferred to the cooling station. Then, the electric push rod is activated to extend and drive the connecting rod and the sealing door to move downward. The opening is blocked by the sealing door. When the sensor detects that the sealing door is closed, a large amount of water is quickly injected into the cooling station by opening the water inlet valve. At this time, the large amount of water will completely immerse and surround the mold, achieving a rapid cooling effect. Compared with the air cooling method, it can achieve rapid cooling and better meet the needs of large-scale production. 2. This utility model sets up a stabilizing plate and rollers between the frame and the transfer station. When the drive gear rotates, the transfer station is raised and lowered by the drive gear cooperating with the rack. At the same time, the rollers can roll along the stabilizing plate during the up and down movement of the transfer station, thereby providing auxiliary support for the transfer station and increasing the stability of the rack movement.

Detailed Implementation

[0019] This specific embodiment is a rapid cooling system for a foam molding machine mold, and its structural schematic diagram is shown below. Figures 1-6 As shown, the system includes a frame 1 and a loading / unloading station 2, a transfer station 3, a heating station 4, and a cooling station 5 mounted on the frame 1. The specific structures of the loading / unloading station 2, transfer station 3, heating station 4, and cooling station 5 on the frame 1 have been disclosed in application number 202410806570.3 and will not be described in detail here. The loading / unloading station 2 is located on the front side of the frame 1, the transfer station 3 is located on the rear side of the frame 1, and the cooling station 5 and heating station 4 are arranged sequentially from top to bottom on the frame 1. The cooling station 5 is... The cooling station 5 is a closed trough. An opening 6 is provided on the back of the cooling station 5. A sealing door 7 is slidably inserted into the opening 6. There is a sealing gasket on the outside of the sealing door 7. After moving downward, the opening 6 is blocked, so that the cooling station 5 forms a water tank. An electric push rod 8 is installed at the top of the frame 1. A connecting rod 9 is fixedly connected to the telescopic end of the electric push rod 8. The bottom end of the connecting rod 9 is fixedly connected to the sealing door 7. A water inlet pipe 10 and a water outlet pipe 11 are installed on the side of the frame 1. A water inlet valve 12 is installed on the water inlet pipe 10, and a water outlet valve 13 is installed on the water outlet pipe 11.

[0020] To better facilitate drainage, such as Figure 2 and Figure 6As shown: In this embodiment, grooves 501 are provided on both the front and rear sides of the bottom wall of the cooling station 5. The top of the drain pipe 11 is a Y-shaped structure and extends to the bottom of the two grooves 501. A cover plate 502 is installed inside the groove 501. The groove 501 is stepped, and the cover plate 502 can be placed directly in the stepped groove. Multiple drainage holes 503 are provided on the cover plate 502. In this way, after a large amount of water is quickly injected into the cooling station 5, it will flow into the grooves 501 on the bottom wall of the cooling station 5 to cool the mold. Then, it will flow to the outside along the Y-shaped drain pipe 11 or be cooled and reused.

[0021] In order to facilitate the control of the opening and closing of the inlet valve 12 and the drain valve 13, in this embodiment, both the inlet valve 12 and the drain valve 13 are electric valves. When a large amount of water is rapidly injected into the cooling station 5, the inlet valve 12 and the drain valve 13 are closed. After the cooling is completed, the inlet valve 12 and the drain valve 13 are opened.

[0022] like Figure 2 and Figure 3 As shown: In this embodiment, a sensor 802 is installed on the outside of the electric push rod 8 via a bracket 801. The sensor 802 is used to detect the opening and closing of the sealing door 7. The sensor 802 can detect the position of the sealing door 7. The sensor 802, the water inlet valve 12 and the drain valve 13 are all connected to the controller.

[0023] To make the lifting of transfer station 3 more stable, such as Figure 2 , Figure 4 and Figure 5 As shown: In this embodiment, the frame 1 includes a base plate, a top plate, and two side plates 103 fixedly connected between the base plate and the top plate. A stabilizing plate 104 is fixedly connected to the side of the two side plates 103 that are far apart. The transfer station 3 includes a transport frame 301, a drive gear 302 mounted on the transport frame 301, and a rack 303 fixedly connected to the stabilizing plate 104. The transport frame 301 is slidably connected to the side plates 103. L-shaped connecting plates 304 are fixedly connected to the lower surfaces of the left and right ends of the transport frame 301. The other end of the L-shaped connecting plate 304 extends to the front side of the stabilizing plate 104 and is rotatably connected to a roller 305. The roller 305 contacts the outer surface of the stabilizing plate 104. A guide rail 105 is fixedly connected to the side of the two side plates 103 that are close to each other. A slider 106 is fixedly connected to the left and right sides of the transport frame 301. The slider 106 is slidably connected to the guide rail 105.

[0024] The drive gear 302 is connected to the drive component in the transfer station 3. When the drive gear 302 rotates, the transfer station 3 is raised and lowered by the drive gear 302 cooperating with the rack 303. At the same time, the transfer station 3 can make the roller 305 roll along the stabilizing plate 104 during the up and down movement, thereby providing auxiliary support for the transfer station 3 and increasing the stability of the rack movement.

[0025] Working principle: By setting up a water tank on the cooling station 5, when the mold needs to be cooled, the mold is transferred to the cooling station 5, and then the electric push rod 8 is activated to extend and drive the connecting rod 9 and the sealing door 7 to move downward. The opening 6 is blocked by the sealing door 7. At this time, the sensor 802 detects that the sealing door 7 is closed, and a large amount of water is quickly injected into the cooling station 5 by opening the water inlet valve 12. At this time, the large amount of water will completely immerse and surround the mold, achieving the effect of rapid cooling. Compared with the air cooling method, it can achieve rapid cooling and better meet the needs of large-scale production.

[0026] All technical features in this embodiment can be freely combined according to actual needs.

[0027] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
