摘要： The application provides a molding apparatus. The molding apparatus comprises a first mold-defining member together with a second mold-defining member, one or more channels, and one or more moveable cores. The first mold-defining member together with the second mold-defining member defines an internal cavity. The channels comprise inlets for receiving molten resin and outlets to the internal cavity. The moveable cores are moveable between a first position and a second position, wherein the moveable core in the second position reduces a volume of the internal cavity and closes the channel outlets. The moveable core is also independently moveable with respect to the first mold-defining member and with respect to the second mold-defining member.

摘要： An apparatus for adjusting die stroke includes a plurality of adjustable helical springs, each of which is equipped with a displacement sensor, a rotation sleeve, and a rotation sleeve driver; a plurality of supporting rods; and a central processing unit. The apparatus is mounted between an oil-pressure cylinder and a top die movable above a bottom die. After the top and the bottom dies are closed to each other, deformation of the adjustable helical springs detected by the displacement sensors and errors measured at different points of molded product released from the dies are sent to the central processing unit for operation. Based on operation results, the central processing unit sends adjusting signals to the rotation sleeve drivers for the same to turn the rotation sleeves and thereby adjusts the helical springs to required modulus of elasticity for use in next cycle of molding process to reduce product errors.
