- the hot melt resin material is filled or injected into the molded product shape space 12 before the filled or injected hot melt resin material is solidified or cured in the mold, That is, when compressed air is injected from the air ejector port 14 into the molded product shape space 12 before the hot melt resin material becomes below the softening point, the hot melt resin is solidified or cured first from the portion in contact with the mold surface. Since the center portion of the material is still in an unsolidified or uncured semi-molten state, the entire hot melt resin material is compressed so as to be pressed against the long-side heat-sealed portion 5c of the laminate film outer case 5. At the same time, the cooling effect is promoted by the injection of compressed air, and as shown in FIG.
- “sink marks” occur due to shrinkage accompanying solidification or hardening as the cooling solidification or cooling hardening progresses.
- the recess Q is formed in a portion that receives the injection of compressed air from the air ejector port 14 in the direction perpendicular to the surface.
- the jet of compressed air is jetted in the same direction as the ejecting direction by the ejector pin 13, the jetting force of the compressed air, together with the ejecting force by the ejector pin 13, moves the edge protector 6 after molding to the lower mold 9.
- the mold is positively released while protruding, and this also provides good mold release properties.
- the jet direction of the compressed air coincides with the direction in which the edge protector 6 formed of the hot melt resin material is pressed against the front or back surface of the long side heat-sealed portion 5c in the laminate film outer package 5. Also, the adhesion of the edge protector 6 to the laminate film outer package 5 is very good.
- positively generating “sink” in a part of the molded product means a decrease in the shape accuracy of the original molded product, and particularly in the design aspect of the molded product.
- the occurrence of “sink” is not allowed in many cases, but the edge protector 6 does not require any design because of its function, so there is no problem. More specifically, if the single battery 1 as shown in FIG. 1 is used as one cell, a plurality of cells are combined into one cell, and then stored in a metal hard case to form a battery module. Therefore, as long as the edge protector 6 can exhibit the function of avoiding the metal touch of the battery 1 with respect to, for example, a metal hard case, the shape accuracy of the edge protector 6 is not particularly problematic.
