摘要： This injection blow molding machine has special provision for maintaining the plastic of a parison on a core rod at the orientation temperature of the plastic; and stretching the plastic of the parison lengthwise of the core rod for orientation in the direction of one axis without any substantial increase in the diameter of the parison. After this orientation in one axis, the temperature is controlled to maintain an orientation temperature, and the plastic of the parison is then blown to a larger diameter so as to obtain orientation in another axis for ''''bi-axial orientation.'''' The core rod is covered by an elastic balloon, and provision is made for obtaining flow of the plastic on the core rod lengthwise of the rod during the first orientation operation.

摘要： This molding machine has stations with molds that open and close, and has an indexing head that rotates periodically to shift core rods from one operating station to the next. A safety gate surrounds the space in which the mold and indexing head are located. The gate has to be raised to give an attendant access to the molds and indexing head, and when the gate is raised there are interferences that prevent the machine from operating, including latches that hold the molds open and limit switches that shut off power to the indexing head motor. There is novel power-operated mechanism for raising and lowering the gate so that all portions of the gate move up and down in synchronism.

摘要： A blow molding machine for making plastic articles has the plastic blown to the desired shape without requiring a blow mold cavity. A plastic coating is applied to a core rod which is covered by an expandible balloon, in deflated condition, hugging the core rod. The extent of expansion of the blown article is regulated by metering the amount of fluid used for blowing; and more accurate control can be obtained by using a liquid for blowing. A stream of air against the outside of the plastic cools the article. By making the wall of the balloon thicker at localized areas the expansion and consequent shape of the article can be controlled. If wide flat bottoms are desired, a baffle can be used for regulating the lengthwise expansion of the balloon and blown article.

摘要： Molding machines commonly have polygonal indexing heads with straight side faces from which core rods extend. Molded articles are stripped from the core rods at a stripping station; and sensing means beyond the stripping station detect any residual molding material that may not have been stripped. Upon detecting such material, the sensing means cause the machine to stop before a mold at the next station closes on the residue on the core rod. This invention moves the sensing devices toward and from the axis of rotation of the indexing head to compensate for the fact that the head is not round and to thereby operate over a greater length of the core rod.

摘要： A plastic container having a bail handle on one side, blown as one-piece with the container, is formed by blow molding in a cavity having a portion into which one side of the parison is displaced to form a handle portion. A shearing operation is then performed on the partially blown container. In this operation part of the handle portion is compressed to a flat condition and displaced from the container between the body of the container and the part of the handle portion that will constitute the actual handle of the final container. The container is then blown to its final size, preferably in a second blowing mold.

摘要： This blow molding apparatus applies a coating to a core rod and then moves the core rod into an inactive position in which it travels through one cycle of the apparatus before being brought into interaction with a blowing and stripping station during a second cycle. This travel of the parison with the core rod in an inactive position allows time for the parison to be brought to a temperature for biaxial orientation before blowing the parison. The cooling can also be used to bring the parison to a condition at which a second coating can be applied over the parison to make a laminated container or other article. The preferred construction has the core rods hinged to an indexing table for movement between active and inactive positions.

摘要： This molding machine has a motor that raises and lowers a core rod indexing head by a distance equal to a portion of the distance moved by the mold half that opens and closes the mold, preferably one-half as much. The control of working fluid to the head-raising motor depends upon the distance moved by the mold operating motor. The exhaust working fluid from one side of the mold operating motor can be used as the working fluid for the head raising motor.

摘要： This indexing head for blow molding apparatus has a plurality of core rods projecting from each of the side faces of the head. A trigger bar is located in a recess of each side face in position to actuate simultaneously all of the valves in the core rods of the face in which the trigger bar is located. This effects blowing of parisons on the core rods when the core rods are at a blowing station. The head has improved and more reliable actuating mechanism for moving the trigger bar. Freely movable balls serve as motion-transmitting means for changing the direction of motion from a thrustor to the trigger bar by cam action of one ball against the other.

摘要： This invention is an improved injection molding apparatus, and more specifically an injection blow molding machine. An injection mold and/or other molds have a movable part that is moved toward and from a fixed part to open and close the mold. Hydraulic motors supplied with high pressure liquid holds the molds closed. In order to conserve high pressure liquid, a small motor is used to open and close the molds and to move a piston of the high pressure hydraulic motor. Liquid under little or no pressure is drawn into the hydraulic motors as they are moved by the small motor. When the molds reach closed position, communication of the hydraulic motors with the low pressure liquid supply is cut off, and high pressure liquid is supplied to the hydraulic motors. The preferred construction has all of the movable parts of the molds connected with a frame and has a single small motor that moves the frame. Special motion-transmitting means maintain the frame against tilting.

摘要： This invention controls the application of a parison to a core rod in the cavity of the injection mold of injection blow molding apparatus. The invention is particularly useful for core rods that include a balloon which covers the outside surface of the core rod and over which the parison is applied. Elastomer material of which the balloon is made is eventually eroded by the hot blast of plastic injection against the end of the core rod in the conventional manner. This invention covers most of the core rod with a protecting metal tube in the mold cavity and applies the plastic as a rolling wave instead of a blast impact.
