Blow molding device capable of continuous processing

1. A blow molding device comprising:

a heating unit configured to heat a molding material; and

molds configured to load and mold the molding material therebetween,

wherein the heating unit includes,

an infrared lamp configured to emit infrared rays,

a reflective mirror configured to concentrate the infrared rays emitted from the infrared lamp, and

a light transmitting body configured to receive the infrared rays concentrated by the reflective mirror and transmit the concentrated infrared rays to the molding material,

wherein the molds are configured to mold the molding material by using a gas pressure applied to surfaces of the molding material that has been heated to a temperature by the infrared rays transmitted from the light transmitting body,

wherein the molds include a first chamber and a second chamber that accommodate the molding material therebetween and define spaces in which the gas pressure is formed,

wherein the first chamber is fixedly coupled to the heating unit, and the first chamber includes a window at one side of the first chamber and a sealing surface at the other side of the first chamber, the window configured to accommodate the light transmitting body of the heating unit therethrough, the sealing surface configured to come into contact with the molding material, the sealing surface and the window configured to form a first space therebetween, and the first space including an inlet port configured to introduce a gas having a pressure and a first discharge port configured to discharge air from the first space,

wherein the second chamber has a loading surface on which the molding material is loaded, the second chamber is configured to be closed as the molding material is placed on the loading surface, the second chamber has a second space having a shape corresponding to a shape into which the molding material is to be molded, and the second space has a second discharge port configured to discharge air therefrom,

wherein the first chamber and the second chamber are configured to be moved between a first position, at which the first chamber and the second chamber are moved to be close to each other such that the molding material is accommodated between the sealing surface and the loading surface, and a second position, at which the first chamber and the second chamber are moved to be spaced apart from each other such that the molding material is loaded on the second chamber or the molded molding material is separated from the second chamber, and

wherein at the first position of the first chamber and the second chamber, the heating unit heats the molding material is heated to the temperature, the inlet port of the first chamber introduces the gas having the pressure into the first chamber, and the second discharge port of the second chamber discharges air from the second chamber, such that the molding material is molded in the second space of the second chamber.

2. The blow molding device of claim 1 , wherein at the second position of the first chamber and the second chamber, the second discharge port is configured to discharge the gas from the second space of the second chamber to apply a negative pressure to the molding material loaded on the loading surface.

3. The blow molding device of claim 1 , wherein at the second position of the first chamber and the second chamber, the gas is discharged from the first space of the first chamber and the second space of the second chamber and the heating unit is configured to heat the molding material in a state in which the molding material is placed between the sealing surface of the first chamber and the loading surface of the second chamber.

4. The blow molding device of claim 1 , further comprising:

sealing elements on the sealing surface of the first chamber and the loading surface of the second chamber, the sealing elements configured to seal the first space and the second space by coming into contact with the molding material.

5. The blow molding device of claim 1 , wherein

the second chamber is configured to be movable upward and downward, by a lifting device, relative to the first chamber and the heating unit, and

the second chamber is further configured to be movable laterally from the first chamber and the heating unit by a turntable or a linear motion device.

6. The blow molding device of claim 1 , wherein

the first chamber and the heating unit are configured to be movable upward and downward, by a lifting device, relative to the second chamber, and

the first chamber and the heating unit are configured to be movable laterally from the second chamber by a turntable or a linear motion device.

7. The blow molding device of claim 1 , wherein

the reflective mirror surround the infrared lamp under the infrared lamp, and

the light transmitting body being at a lower end of the reflective mirror and configured to transmit the infrared rays, which are received by the reflective mirror from the infrared lamp and are reflected and concentrated by the reflective mirror to the molds.

8. The blow molding device of claim 1 , wherein the light transmitting body is a quartz rod.

9. The blow molding device of claim 8 , further comprising:

an anti-reflection treated layer on a lower end surface of the quartz rod, the anti-reflection treated layer configured such that the infrared rays passing through the quartz rod is applied to the molding material without being reflected.
