Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the functions of the invention easy to understand, the invention is further explained by combining the specific embodiments.
As shown in fig. 1 to 4, a vacuum system for a foam molding apparatus includes a vacuum suction pipe 1, a cylinder 2, a cooling tank 3, a ring support 4, a water inlet pipe 5, a water outlet pipe 6, and a piston 12; promote piston 12 through cylinder 2, make vacuum exhaust tube 1 can bleed and inject gas, realize vacuum and bleed and inject two functions of gas, vacuum exhaust tube 1 is installed in cooler bin 3 simultaneously, cools off the air in vacuum exhaust tube 1 through leading to frozen water in the cooler bin 3, plays and makes it possess the function of cooling effect for gaseous cooling.
The side of the piston 12 is also fixedly connected with a rubber ring 13, and the rubber ring 13 is made of nitrile rubber. The rubber ring 13 made of the nitrile rubber has good wear resistance, aging resistance and air tightness, and air leakage is avoided during air suction and injection.
The annular supports 4 are provided with two annular supports, and each annular support 4 is provided with 10 through holes 40 at equal intervals. Two ring carrier 4 can play support and balanced effect well, and through-hole 40 guarantees that the inside frozen water of cooling tank 3 freely circulates.
The water inlet pipe 5 is provided with an electromagnetic valve 50. The solenoid valve 50 controls the water inlet of the water inlet pipe 5, the outlet of the water outlet pipe 6 faces upwards and is positioned above the left side face of the cooling box 3, and only when the water inlet pipe 5 enters water, the water is discharged through the water outlet pipe 6.
The vacuum exhaust tube 1 is made of a copper alloy material, and the cooling box 3 and the annular bracket 4 are both made of stainless steel materials. Copper has excellent thermal conductivity, so that ice water can better cool the air in the vacuum exhaust pipe.
The specific implementation mode and principle are as follows:
during foam plastic suction molding, vacuum air extraction equipment is needed, the vacuum degree required by foam plastic suction of common foam products is not too high, the device is designed and used by I, the purchased vacuum pump can be completely replaced, meanwhile, the device has the function which the common vacuum pump does not have, and the production requirement of common foam plastic suction molding is met better;
when vacuum air extraction is needed, the cylinder 2 is started, the telescopic shaft 20 retracts to drive the piston 12 to move backwards, negative air pressure is formed in the vacuum extraction pipe 1, air in the mold is extracted to form vacuum, the vacuum air extraction function is achieved, after the air is extracted into the vacuum extraction pipe 1, the vacuum extraction pipe 1 is located in the cooling box 3, therefore, the electromagnetic valve 50 is opened, ice water is injected into the cooling box 3 through the water inlet pipe 5, and the vacuum extraction pipe 1 is made of copper alloy materials and has excellent heat conductivity, so that the ice water can rapidly cool hot air in the vacuum extraction pipe 1 (the hot air is required to be heated before foam in the mold is formed), and the function of cooling the air is achieved;
after the foam is formed in the mold, the cylinder 2 is started again, the telescopic shaft 20 extends out and drives the piston 12 to move forwards, and the air cooled in the vacuum exhaust tube 1 is pushed back into the mold, so that the foam forming quality is improved, and the formed foam is easier to separate from the mold.
When needing to trade water for cooling tank 3, open solenoid valve 50, intake through inlet tube 5, because inlet tube 5 fixed connection is in the right flank below of cooling tank 3, and be equipped with through-hole 40 again on the ring carrier 4, and outlet pipe 6 export up and be located the left surface top of cooling tank 3, so only when inlet tube 5 intakes, just can discharge water through outlet pipe 6, and then realize trading water.
Based on the above, the utility model discloses simple structure uses in a flexible way, promotes the piston through the cylinder, makes the vacuum exhaust tube can bleed and inject gas, realizes vacuum and bleed and two functions of injection gas, and the vacuum exhaust tube is installed in the cooler bin simultaneously, cools off the air in the vacuum exhaust tube through leading to frozen water in to the cooler bin, plays and makes it possess the function of cooling effect for gas cooling, the utility model discloses simple and practical possesses vacuum and bleed and inject two functions of gas simultaneously, and can give gas cooling.
