The present invention is an apparatus for manufacturing EPS used as a heat insulating material, which is a kind of building material. It relates to an EPS manufacturing device capable of continuously and mass-producing EPS blocks while circulating a conveyor belt.

In general, expandable polystyrene (EPS) is expanded polystyrene by the action of a foaming agent, and is called various names such as expanded polystyrene, styrofoam, and styrofoam, and is abbreviated as EPS after the English initials.

The EPS is a colorless and transparent thermoplastic material, becomes soft at 100 ° C. or higher, becomes a viscous liquid at about 185 ° C., and has strong properties such as acids, alkalis, oils and alcohols. The EPS is white, light, has good insulation properties, and has excellent sound insulation and molding processability, so it is suitable for sea buoys, other decorative cups or bowls, plates, shell-shaped containers, meat packaging containers, egg packaging containers, electronic products or other fragile It is widely used as packaging materials for transportation of goods, building materials with wood grain patterns, decorative furniture, and boxes for agricultural and marine products. In addition, it is used as a wall material for meat refrigeration warehouses, exterior of frozen pipes, wall and ceiling materials for prefabricated houses, stage equipment for televisions, artificial snow, etc.

The EPS makes foam beads by simultaneously adding a foaming agent under pressure while performing suspension polymerization of the styrene monomer, and heating the foamable beads to a high temperature so that the foaming agent injected therein expands. During the expansion process, the softened styrene polymer beads are inside It is produced by inducing to form fine bubbles in

Since about 98% of the volume of this expanded polystyrene is air and the remaining 2% is made of styrene resin, it is lighter than anything else, has good insulation by air, and has excellent water resistance, buffering and sound insulation properties. . Using such characteristics of expanded polystyrene, it is in the limelight as an internal and external insulation material for buildings, and various types of insulation materials are developed and used.

In order to manufacture an insulator using such an EPS, an injection molding method is mainly used. Looking at the injection molding apparatus for manufacturing insulation materials, a fixed frame and a movable frame are provided, a hopper for accommodating foam beads, which is a raw material, is provided on the fixed frame side, and the movable frame is moved toward the fixed frame by supplying the foam beads to the mold of the injection device The molded EPS is separated from the mold of the injection device.

In the case of this process, it is difficult to mass-produce because only a single EPS block can be produced per one injection device, and a plurality of injection devices must be provided for mass production, but it is expensive, so it is difficult to provide a plurality of them in reality.

In addition, since the EPS raw material injected into the mold of the injection device is in a heated state for molding, it is easy to handle after being separated from the mold through a cooling process, so it must be separated from the mold and moved to a separate space for cooling. Since this requires more equipment and space to separately move the EPS block for cooling, space and cost aspects are inevitably burdened.

In addition, there is a disadvantage in that it takes a very long time to manufacture the EPS insulator because a cutting process tailored to a certain size can be performed only after the molded EPS block is cooled.

Therefore, in order to manufacture a heat insulating material, which is a kind of building material, using an injection molding method to manufacture a heat insulating material using EPS, mass production is possible with a short manufacturing time, and development of a manufacturing device capable of reducing production costs has emerged.
