Description

Technical Field

[0001] The utility model relates to the technical field of condensation of a foam molding machine, in particular to a condensation device of an EPS foam molding machine. Background Art

[0002] EPS foam is made of polystyrene resin, and is heated and foamed at high temperature by adding auxiliary materials such as foaming agent. It has a unique hard closed-cell structure. EPS foam has many excellent properties, such as good thermal insulation, light weight, strong self-reliance, impact and vibration resistance, sound insulation, moisture resistance, vibration reduction and excellent dielectric properties.

[0003] For example, the Chinese utility model patent (CN 214214522 U) discloses a condensing device for an EPS foam molding machine, including a shell of the condensing device, an air inlet pipe is arranged inside the shell, a heat exchange pipe is fixedly arranged at the lower end of the air inlet pipe, the heat exchange pipe is connected to a primary condensing device through a pipeline, and an exhaust pipe is arranged at the upper end of the shell. The condensing device for the EPS foam molding machine can perform preliminary cooling of the part with a higher temperature at the upper end of the air inlet pipe through the primary condensing device, so as to avoid a large temperature difference and damage to the air inlet pipe.

[0004] However, in the above patent, when cooling treatment is carried out, the cooling liquid will gradually heat up, and the liquid will evaporate under high temperature conditions, increasing the pressure inside the equipment. It is necessary to continuously introduce cooling liquid for cooling. The introduction of liquid requires continuous flow or manual operation, and the temperature cannot be effectively controlled. In addition, the patent lacks automated control. This design drives the connecting rod to move by the sealing block being pushed out by pressure, so that when the temperature is too high and the pressure is too high, the coolant is automatically discharged and replaced. No worker supervision is required, saving personnel costs. For this reason, a condensing device of an EPS foam molding machine is required. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. By setting the sealing block, the inside of the cooling box absorbs the heat of the pipeline, causing the water to evaporate. The pressure generated can push the sealing block to slide in the sliding groove opened by the limit block, and push the sealing block and the fixed plate out to a certain position. The air pressure leaks out from the pressure relief port, reducing the internal pressure and temperature.

When it reaches a certain position, the trigger button opens the solenoid valve, so that water can flow in and out of the water inlet and outlet at the same time, realizing automatic regulation, effectively reducing the temperature of the water inside the cooling box and performing circulating cooling.

[0029] Among them, Figure 3 As shown, the limiting tube 3 is provided with a groove which matches the spring 4, which is conducive to the spring 4 being able to be stabilized in the groove of the limiting tube 3 when stretched, and preventing the limiting tube 3 from deforming and rotating when the fixing plate 7 is raised or lowered, thereby stabilizing the direction and improving stability.

[0030] Among them, Figure 3 As shown, six groups of limit tubes 3 and springs 4 are provided, and the positional relationship of the six groups of limit tubes 3 and springs 4 is symmetrically distributed about the center of the limit block 5, which is conducive to providing power for the lifting, lowering and retracting of the fixed plate 7, and the sealing block 6 and the fixed plate 7 are pushed out by air pressure and retracted by the spring 4.

[0031] Among them, Figure 3 As shown, the limit block 5 is provided with a sliding groove that matches the sealing block 6, which is conducive to the steam pressure inside the cooling box 1 to push the sealing block 6 out of the groove of the limit block 5 and leak from the pressure relief port 8 to reduce the pressure.

[0032] Example 2

[0033] like Figure 1 , Figure 2 and Figure 4As shown, this embodiment further illustrates Example 1, the outer wall of the fixed plate 7 is fixedly connected with a connecting rod 9, one end of the connecting rod 9 is fixedly connected with a first rack 10, one side of the first rack 10 is meshedly connected with a gear 11, the outer wall of the gear 11 is fixedly connected with a rotating shaft 12, the outer wall of the first rack 10 is slidably connected with a limiting plate 13, the outer wall of the gear 11 is meshedly connected with a second rack 14, the outer wall of the second rack 14 is fixedly connected with a connecting column 15, one end of the connecting column 15 is fixedly connected with a fixing block 16, the bottom of the fixing block 16 is fixedly connected with a trigger pin 17, the top of the cooling box 1 is fixedly connected with a button 18, the outer wall of the cooling box 1 is fixedly connected with an inlet 19, the outer wall of the cooling box 1 is fixedly connected with a discharge port 20, the outer wall of the cooling box 1 is fixedly connected with a water inlet 21, the outer wall of the water inlet 21 is provided with a solenoid valve 22, the outer wall of the cooling box 1 is fixedly connected with a drain port 23, and the interior of the cooling box 1 is provided with a pipe 24.
