    摘要： A molding-forming method, a molding mold, and a molding production apparatus with which efficient burrs removal is possible without requiring a large apparatus. A molding production method includes, in addition to a molding being formed inside a mold, burrs formed around the molding are separated from the molding. After formation of the molding, air is blown inside the mold on at least a portion of the burrs formed around the molding to cool the same, a projecting member is projected toward the cooled burrs, and the burrs are separated from the molding. After pressing the burrs toward the projecting member by the air blowing, the burr is pressed toward the mold surface facing the projecting member by projection of the projecting member to separate the burr from the molding.

    摘要： The present invention provides a manufacturing method of a molded product by which the cutting accuracy of a burr provided on the peripheral surface of the molded body can be improved. According to the present invention, provided is a manufacturing method of a molded product, comprising a measurement step; a correction step; and a burr cutting step, wherein, in the measurement step, a position of at least one point on a peripheral surface of a molded body is measured while the molded body is in a positioned state, in the correction step, a master cutting line is corrected on the basis of a measurement result in the measurement step to determine a corrected cutting line, and in the burr cutting step, a burr provided on the peripheral surface of the molded body is cut according to the corrected cutting line.

    摘要： A mold separation method includes the following steps: providing a mold separation device including a carrying mechanism, a scraping mechanism, and two separation mechanisms, wherein the scraping mechanism is disposed at an edge of the carrying mechanism, and the separation mechanisms are disposed at the edge of the carrying mechanism and are located on two opposite sides of the scraping mechanism; placing a first mold and a second mold bonded to the first mold on the carrying mechanism; causing the scraping mechanism to scrape off a spilled glue produced when the first mold is bonded to the second mold; and after scraping off the spilled glue, causing the separation mechanisms to pull open the first mold and the second mold so that the first mold and the second mold are separated from each other.

    摘要： Methods for post-mold processing a Venturi device for generating vacuum are disclosed that improve the evacuation time thereof. The methods include providing a molded Venturi device having a body defining a Venturi gap between an outlet end of a converging motive passageway and an inlet end of a diverging discharge passageway, where the outlet end defines a motive exit having flash extending radially inward and the inlet end defines a discharge inlet having flash extending radially inward. Then, the method includes positioning the molded Venturi device with an inlet end of the converging motive passageway facing a blasting nozzle or with an outlet end of a diverging discharge passageway facing a blasting nozzle, and propelling blasting media into the motive inlet or the discharge exit of the Venturi device to remove the flash in the motive exit and in the discharge inlet, or vice versa.
