Claims

A mold having a first mold and a second mold arranged to face each other;
A supply mechanism for supplying a resin molding target to a mold surface of any one of the first mold and the second mold,
A positioning mechanism for positioning the resin molding target on the guide member on the mold surface;
A mold clamping mechanism for clamping the molding die,
A light-emitting element that emits irradiation light,
A first light receiving element provided in the supply mechanism and capable of receiving the irradiation light;
A determination unit for determining the positioning of the resin molding target,
The one mold is provided with a first emission passage hole that allows the irradiation light from the light emitting element to pass therethrough,
The determination unit determines whether the resin molding target is normally positioned on the guide member based on detection of the irradiation light passing through the first emission passage hole by the first light receiving element. Resin molding equipment.

When the first light receiving element does not detect the irradiation light, the determination unit determines that the resin molding target is properly positioned on the guide member, and the first light receiving element detects the irradiation light. The resin molding apparatus according to claim 1, wherein when it is determined that the resin molding target is not properly positioned on the guide member.

3. The resin according to claim 1, wherein the first emission passage hole is provided in a region on the guide member side where the resin molding target is arranged in a state where the resin molding target is in contact with the guide member. 4. Molding equipment.

A light guide unit for guiding the irradiation light emitted from the light emitting element to the first emission passage hole is provided on the one mold or the platen to which the one mold is attached,
4. The resin molding device according to claim 1, wherein an optical member that allows the irradiation light to pass therethrough is provided in the light guide unit. 5.

The light emitting element is provided in the supply mechanism,
5. The resin molding apparatus according to claim 4, wherein the one mold is provided with an incident passage hole for passing the irradiation light emitted from the light emitting element and leading the irradiation light to the light guide.

In a state in which the resin molding object is in contact with the guide member, irradiation light emitted from the light emitting element or another light emitting element is passed through a region on the opposite side of the guide member where the resin molding object is arranged. A second emission passage hole is provided in the one mold,
The resin molding apparatus according to any one of claims 1 to 5 , wherein the supply mechanism includes a second light receiving element capable of receiving the irradiation light having passed through the second emission passage.
