Compression molding die, resin molding device, resin molding system, and method for manufacturing resin molded product

A compression molding die, comprising:

• a first mold;
• and
• a second mold disposed above the first mold to face the first mold, wherein:
• the first mold includes a bottom surface member and a side surface member;
• the bottom surface member includes an upper surface on which a resin material can be disposed, and an outer peripheral surface that extends downward from the upper surface;
• the side surface member includes an inner peripheral surface that surrounds the outer peripheral surface of the bottom surface member;
• a cavity of the first mold is formed by at least the upper surface of the bottom surface member and the inner peripheral surface of the side surface member;
• a space is providable in the first mold by a step in at least one of the outer peripheral surface of the bottom surface member and the inner peripheral surface of the side surface member;
• the first mold further includes a gas inlet through which gas is introducible into the space, a gas outlet through which the gas introduced into the space is dischargeable, and a seal member below the space;
• the step includes a first step in the outer peripheral surface of the bottom surface member, and a second step in the inner peripheral surface of the side surface member, the second step disposed adjacent to and separate from the first step;
• the first step includes a first outer peripheral surface that extends downward from the upper surface of the bottom surface member, a second outer peripheral surface that extends from the first outer peripheral surface to an outer side, and a third outer peripheral surface that extends downward from the second outer peripheral surface;
• and
• the space is formed by both of the first step in the outer peripheral surface of the bottom surface member and the second step in the inner peripheral surface of the side surface member.
