Abstract: The present invention provides a position mechanism including a locating body. The locating body defines a locating cavity and a receiving chamber communicating with the locating cavity. A locating stopper is received in the receiving chamber of the locating body with an end thereof toward the locating cavity, and an elastic component is received in the receiving chamber of the locating body and resiliently biases the locating stopper into the locating cavity.

Abstract: A mold with unloading mechanism includes an upper insert embedded in an upper plate, a lower insert embedded in a lower plate and matching the upper insert to define a cavity therebetween for molding the product, a bottom clamping plate located under the lower plate via a padding plate, a pusher penetrating through the bottom clamping plate to push an ejector plate assembly movably received in the padding plate, two unloading pins, a stroke pin and an elastic element. The bottom of the unloading pin is fixed in the ejector plate assembly and the bottom of the stroke pin is movably configured in the ejector plate assembly. The top of the unloading pin and the stroke pin movably penetrates through the lower plate and the lower insert to push the product. The elastic element is against the bottom clamping plate and the bottom of the stroke pin.

Abstract: An ejector blade comprises a pin shaft and a safeguard. The pin shaft includes an enlarged circular head. The head is an integrally molded portion of the pin shaft. Furthermore, the pin shaft has a pillar part connected to the head and a blade part extending from the pillar part. Each side of the blade part defines an integrally molded support part thereon for supporting the thin blade part. The safeguard disposed in a core plate of a mold is cylindrically shaped with a diameter longer than the support part. The safeguard further defines a first axial passage for allowing the blade part to pass therethrough and a second axial passage for receiving the support part therein.
