20100119644 | MOULD FOR INJECTION MOULDING OF TUBES HAVING SLIM WALLS AND BEING MADE OF PLASTIC - The invention relates to a mould for injecting tubes having slim walls made of a plastic material. The mould, destined to make tubes having an outlet mouth for a product and a lateral wall delimiting the space destined to contain the product to be packed, comprises an upper punch and a lower punch which are inserted in an external body or matrix of the mould to define the space to be filled with the injected plastic material; the upper punch comprises a projection which occupies the internal part of the outlet mouth and extends below the lower end of the mouth; the lower punch comprises a cavity internally of which the projection is inserted; injection channels are afforded between the projection and the cavity, which channels flow into a single injection manifold are reach inlet points to a space of the mould destined to receive the injected material. | 05-13-2010 |
20110086125 | INJECTION DRIVE APPARATUS FOR INJECTION MOLDING MACHINE - An injection drive apparatus for injection molding machines is revealed. Liquid material is fed into a mold smoothly by a material feeding screw of a material feeding mechanism. Then a reaction force is generated to push the material feeding screw when the material feeding hole is nearly full of the material. Thus the material feeding screw and the slide mechanism assembled therewith are pushed to move backward. Later the injection mechanism is driven by the slide mechanism to move and act on the drive screw. Thus the slide mechanism threaded with the drive screw is driven to push the material feeding screw moving forward and squeezing the material for injection molding. Therefore, the load of the motor is reduced dramatically and the yield rate of the products produced by injection molding is increased due to the two-stage action-feeding of the material and squeezing of the material for injection. | 04-14-2011 |
20110212214 | RUNNER SYSTEM FOR SUPPLYING MOLDING COMPOUND - A runner system for a molding apparatus comprises a plurality of runner networks, each runner network further comprising a mold supply pot having a first side and a second side opposite to the first side. A plurality of molding cavities are located on the first and second sides of the mold supply pot, and a plurality of runners are operative to channel molding compound from each mold supply pot to the plurality of molding cavities. At least one of the mold supply pots comprises a different number of runners located on the first side which are connected to the mold supply pot as compared to a number of runners located on the second side which are connected to the mold supply pot. | 09-01-2011 |
20120034335 | Injection Moulding Method and Apparatus - The invention is directed to a method and an apparatus for the production of three-dimensionally thin products using injection moulding of polymer based material. By dividing one of the mould halves in at least two groups of elements, whereby at least a first group of at least one element forms a rim cavity and a stop, defined as an area of the element contacting the other halve if the mould is in the closed position, and at least a second group of at least one element forms the main body part of the cavity, whereby all the elements together form with the other mould halve one cavity, and whereby each of the groups of elements is connected to its own means for clamping, it is possible to produce a set of different products with a constant rim thickness and a variable thickness of the main body part of the product. | 02-09-2012 |
20120156325 | Multiple-Gate Injection Molding Apparatus - One or more nozzles define separate nozzle channels. The nozzles are coupled to a manifold, so that each of the nozzle channels communicates with a different mold gate. A molding material distribution insert is coupled to the manifold and has a body defining a distribution channel and a plurality of drop channels equal in number to the nozzle channels. The distribution channel is an open distribution channel formed on an outer surface of the body and enclosed by the manifold. The drop channels intersect the distribution channel and exit the body at a different one of the nozzle channels. A valve pin bushing can extend into the drop channels. Valve pins can extend from actuators, through the valve pin bushing and the drop channels, and to the mold gates. A valve pin holder can be coupled to the actuator and coupled to heads of the valve pins. | 06-21-2012 |

20090004325 | Device for Filling an Extruder with Pretreated Thermoplastic Material - A device for filling an extruder, which can optionally be an external extruder, with pretreated thermoplastic plastics material, in particular PET, has at least one evacuatable container ( | 01-01-2009 |
20140134286 | LIQUID RESIN MOLDING APPARATUS - In a liquid resin molding apparatus including a mold, an injection machine, a metering/supplying mechanism for metering a liquid resin material and supplying a metered amount of liquid resin material to the injection machine, and a pump for pressure-feeding the liquid resin material to the metering/supplying mechanism, the pump is a piston pump having a piston and an actuator for reciprocating the piston, and a discharge pressure of the piston pump is set to be at least 1.5 times a supply pressure with which the liquid resin material is supplied to the metering/supplying mechanism. A pressure reducing valve is disposed in a supply path extending from the piston pump to the metering/supplying mechanism, so as to reduce a pressure of the liquid resin material from the discharge pressure to the supply pressure. | 05-15-2014 |

20080268091 | Injection Unit - The invention is directed to an injection unit, in particular for an injection molding machine, comprising a screw which is guided in a plastication cylinder in a rotatable and axially movable manner and via which plastic material undergoes plastication and can be injected into a tool cavity. The screw is driven via an electric drive including an electric motor and is operatively connected to a support cylinder having a pressure chamber to which dynamic and/or support pressure can be applied during plastication and injection. The electric motor is coupled to a hydrostatic machine which during plastication is driven by the pressure medium displaced from the pressure chamber and which during injection conveys pressure medium into the pressure chamber so as to build up support pressure. | 10-30-2008 |

20110206797 | Molding Machine - Intended is to provide a molding machine using a built-in type motor as an injecting electric motor. In this molding machine, a mounting structure for such a transmission mechanism from a rotational motion to a linear motion, as changes the rotation of the built-in motor into the linear motion thereby to transmit the linear motion to an injecting member, is simplified to improve the assembling workability. For this improvement, a sleeve is fixed in the rotor of the built-in type motor. In the hollow portion of the sleeve, a screw shaft or the rotating portion of a ball screw mechanism and the sleeve are connected and fixed by a connecting member. A nut member or the straight portion of the ball screw mechanism is fixed on a member for performing straight motions together with the injecting member. | 08-25-2011 |
