[0002] Curing refers to the production process of heating, curing, and drying components in the electronics industry and other industries to enhance the bonding stress of materials. The machinery that carries out this process is a curing oven. A resin curing oven is a curing process that involves heating the workpiece to a high temperature and then maintaining that temperature. This process is called artificial curing. If the workpiece is left to cure at room temperature or under natural conditions for a long time, this process is called natural curing. The purpose of curing is to enhance the bonding stress of materials.

[0024] As mentioned in the background section, existing hot-press curing ovens cannot achieve uniform heating of workpieces, resulting in differences in workpiece molding.

Therefore, this disclosure proposes a structure that can achieve uniform heating and rapid cooling.

[0025] Example 1

[0026] Please see Figure 1 A vacuum hot-press curing oven for resin grinding blocks includes a base 1, which is stepped. A cabinet 2 is installed on the upper surface of the base 1. To facilitate the curing of the resin grinding blocks, a heating furnace 11 is fixedly connected to the middle of the inner cavity of the cabinet 1, and the opening of the heating furnace 11 faces forward for easy material feeding. To prevent heat loss, a cabinet door 9 is movably connected to the right side of the front face of the cabinet 2. To clearly understand the temperature inside the cabinet 2, a display screen 10 is fixedly connected to the upper part of the front face of the cabinet door 9.

[0027] Please see Figure 1To ensure that the temperature inside cabinet 2 does not drop too quickly, cabinet 2 needs to be evacuated. Specifically, a vacuum port 3 is connected through the left side of the upper end face of cabinet 2. At the same time, special gas needs to be injected into the interior of cabinet 2. An inflation pipe 7 is connected through the right side of the upper end face of cabinet 2. For easy connection, a flange 8 is fixedly connected to the upper end face of the inflation pipe 7. To facilitate the cooling of the heating furnace 11, an air-cooling device is installed on the front side of the upper end face of cabinet 2, and the end of the air-cooling device extends into the interior of cabinet 2.

[0028] Please see Figure 4 In order to increase the temperature inside the heating furnace 11 and ensure that the heating furnace 11 is heated evenly, a heating wire 17 is provided inside the heating furnace 11, and the heating wire 17 is spiral in shape. The spiral heating wire 17 can ensure that the resin grinding block inside the heating furnace 11 is cured quickly and evenly.

[0029] Please see Figure 2 In order to further ensure that the internal temperature of the heating furnace 11 does not drop rapidly, the insulation block 12 is a ceramic insulation block. The insulation block 12 is evenly bonded inside the inner cavity of the heating furnace 11, and there are eight sets of insulation blocks 12 arranged in a ring array on the inner wall of the inner cavity of the heating furnace 11.

[0030] Please see Figure 1 and Figure 2 To quickly regulate the temperature inside the heating furnace 11, a wind-cooling device is constructed using a fan 4, a connecting pipe 5, an air supply pipe 6, an insulation ring 13, an exhaust port 14, and a plug 15. The fan 4 is fixedly connected to the front of the upper end of the cabinet 2, and the connecting pipe 5 is fixedly connected to the air outlet of the fan 4. An insulation ring 13 is installed outside the heating furnace 11, and the front and rear ends of the insulation ring 13 are fixedly connected to the front and rear ends of the inner cavity of the cabinet 2, respectively. To facilitate the entry of cold air into the insulation ring 13, an air supply pipe 6 is fixedly connected to the upper part of the outer wall of the insulation ring 13, and the lower end of the air supply pipe 6 is connected to the insulation ring 13. The upper end of the air supply pipe 6 extends through to the upper end of the cabinet 2 and is connected to the end of the connecting pipe 5. To quickly exhaust and cool down, exhaust ports 14 are evenly distributed on the rear end of the cabinet 2, and the exhaust ports 14 are connected to the inner cavity of the insulation ring 13. To prevent heat loss, a plug 15 is installed inside the exhaust port 14.

[0031] Please see Figure 2 In order to quickly understand the temperature of the inner cavity of the cabinet 2 and the insulation ring 13, a temperature sensor 16 is fixedly connected to the outer wall of the insulation ring 13. The temperature sensor 16 is connected to the display screen 10 through a wire, and the display screen 10 is a temperature display screen.

[0032] Example 2

[0033] Please see Figure 2In order to further ensure the heat dissipation between the insulation ring 13 and the heating furnace 11 and achieve the conditions of air cooling, four sets of exhaust ports 14 are provided, and the four sets of exhaust ports 14 are arranged in a ring array on the rear end face of the cabinet 2.

[0034] Working principle: During use, connect the heating wire 17, temperature sensor 16, and fan 4 via an external power supply. Open the cabinet door 9 using the handle, place the resin to be cured inside the heating furnace 11, close the cabinet door 9, turn on the heating wire 17, and simultaneously connect the air inlet of the vacuum pump to the vacuum interface 3 to ensure a vacuum inside the cabinet 2. At the same time, connect the inert gas connecting pipe to the flange 8 to fill the cabinet 2 with inert gas to prevent rapid heat loss from the cabinet 2. According to the temperature displayed on the display screen 10, when the temperature is too high, stop the heating wire 17 from working and start the fan 4. The fan 4 blows air through the connecting pipe 5 and the air supply pipe 6 into the space between the insulation ring 13 and the heating furnace 11. Remove the blockage 15 to ensure that the heat from the outer wall of the heating furnace 11 is discharged. Through the heat transfer effect, the cold air cools the heating furnace 11 to improve the efficiency of resin curing.
