Double compression molding machine and manufacturing method of product

A double compression molding machine comprising:

• a plunger;
• a supporting member configured to support an internal part to be sealed in an inner portion of a product to be molded;
• a mold having a cavity in which the product is molded,
• a cylinder hole which communicates with the cavity and into which the plunger is inserted,
• an insertion hole which communicates with the cavity and into which the supporting member is inserted and a fixing member which fixes the internal part in the cavity;
• a plunger driving apparatus configured to press a resin material inserted in the cylinder hole into the cavity such that the product is molded when the plunger is at a retracted position by advancing the plunger inserted in the cylinder hole from the retracted position toward the cavity;
• and
• a supporting member driving apparatus configured to press the supporting member inserted in the insertion hole until the supporting member abuts on the internal part fixed in the cavity and extracts the supporting member inserted in the insertion hole from the cavity.
