| 20080286405 | APPARATUS FOR INJECTION MOLDING - An injection molding apparatus includes a first mold half, a second mold half opposite to the first mold half, an eject pin, a component collector and a buffer device. The eject pin penetrates through the first mold half. The component collector is configured for receiving the molding component molded. The buffer device includes a buffer plate, a connection plate and an elastic element. The elastic element includes two elastic arms connected with each other. The two elastic arms form an angle θ in a range 0°<θ<180° in its natural state and partly inserting into the buffer plate and the connection plate respectively. The buffer device is disposed at a same side as the first mold half and the buffer plate is adjacent to the second mold half. The buffer device is configured for buffering the molding component during a knockout process. | 11-20-2008 |
| 20110045123 | Die for Injection Molding Glass with Frame - In an injection molding die, there is defined a cavity for a frame or a cavity for the frame and an auxiliary cavity communicating with the cavity for the frame, and into the cavity for the frame or the auxiliary cavity, there is injected a melted resin from a runner through a gate, and a section of the gate has a width of 1 to 5 mm in the direction of a thickness of a plate glass and a width of 10 mm or more in the direction parallel with a side of the plate glass but smaller than a side length of the plate glass. When this die is practically used, a load that would be applied to a peripheral portion of the plate glass during injection molding is reduced, so that when the frame is integrally molded to the plate glass by injection molding, undesired breakage of the plate glass is suppressed. | 02-24-2011 |
| 20110244070 | NOZZLE VALVE GATE APPARATUS WITH WIPER SEAL - A nozzle valve gate for injecting hot plastics into an injection mold includes a body having a passage for flow of the plastics to an outlet and forming an actuator chamber. A nozzle part is connected to the body and extends longitudinally to a nozzle tip having an injection aperture. The nozzle part has a flow passageway connected to the plastics outlet for conducting the plastics melt to the injection aperture and a machined bore forming a guide passageway. A valve pin is movable in the guide passageway between open and closed positions. A piston is connected to the pin and is slidable in the actuator chamber. An elastomeric wiper seal extends around the valve pin adjacent the machined bore, is wear resistant, and can withstand high temperatures of at least 200° C. A micro gap is formed between the pin and the machined bore. | 10-06-2011 |
| 20120082753 | INJECTION MOLDING SYSTEM INCLUDING A MELT FILTER, THE FILTER BEING LOCATED BEFORE FIRST INSTANCE OF MELT ACCUMULATION - There is provided an injection unit. The injection unit comprises an extruder that is structured to continuously melt, in use, a molding material; a nozzle that is connectable, in use, to a mold; a melt accumulator that is structured to selectively buffer and transfer, in use, the molding material towards the nozzle, the melt accumulator including a first melt accumulator and a second melt accumulator selectively connectable to the extruder via a distribution assembly, and wherein each of the first melt accumulator and the second melt accumulator defines a respective melt accumulation volume; the melt accumulation volume being configured to accumulate and hold, for a first time after being molten by the extruder a volume of molding material sufficient to transfer for downstream processing; a melt filter placed before the melt accumulation volume, such that the molding material if subjected to filtering prior to entering the melt accumulation volume, the melt filter being configured to remove contaminants from the molding material. | 04-05-2012 |
| 20120195996 | PLASTIC MATERIAL INJECTION MOLDING SYSTEM - A plastic material injection molding system includes a feeding nozzle, a forming mold having a cave therein, and a material-passing mold having a runner therein. The runner communicates both the feeding nozzle and the cave, and has two curved parts therein for slowing down the plastic material injected from the feeding nozzle in order. | 08-02-2012 |
| 20140255536 | INJECTION APPARATUS - An injection apparatus includes a pressure accumulating portion, which is connected to an injection cylinder, and a speed reduction mechanism, which reduces the speed of the injection cylinder arranged in the injection apparatus. The speed reduction mechanism includes an actuating member, which moves integrally with a rod of an injection cylinder rod, and a restriction member, which is arranged in a flow passage for draining or supplying hydraulic oil from or to the injection cylinder, and variably narrows the flow passage in conjunction with movement of the actuating member. | 09-11-2014 |
| 20150079221 | TWO STAGE INJECTION UNIT ROTARY VALVE - An injection unit for an injection molding machine includes a nozzle for dispensing melt to a mold, and a valve housing having a first port in fluid communication with the nozzle. The valve housing has a second port and a third port. A plasticizing barrel is in fluid communication with the second port. A shooting pot is in fluid communication the third port. A valve closure member is mounted in the valve housing. The valve closure member is moveable between a first position in which the first port is in fluid communication with the third port and in fluid isolation of the second port, and a second position in which the second port is in fluid communication with the third port and in fluid isolation of the first port. When in at least one of the first and second positions, fluid communication is provided between the respective ports through a gap provided between an outer surface of the closure member and an inner surface of the valve housing. | 03-19-2015 |
| 20150110917 | SIDE ACTUATED SHOOTING POT - An injection molding system having a shooting pot assembly is disclosed. In one embodiment, the shooting pot assembly is in fluid communication with a mold and has an actuation direction that is substantially perpendicular to an injection axis of material injected into a mold cavity. In another embodiment, a shooting pot actuation system is a mounted on a side of a hot runner. In certain embodiments, the shooting pot actuation system includes a linear actuator operatively coupled with the shooting pot assembly to actuate the shooting pot assembly. | 04-23-2015 |

| 20090274790 | SHOOTING POT FOR FEEDING MULTIPLE NOZZLES - A hot runner system including a shoot pot system for transferring melt from a single shooting pot to multiple nozzles. Melt is fed from a source of melt into the cavity through the multiple nozzles, and a valve isolates melt in the cavity from melt in the source. A plunger within the cavity is driven forward to inject melt in the cavity into a mold cavity at high pressure without significantly increasing the pressure of melt in the source. The plunger optionally functions as both the plunger and the valve by opening and closing communication between the cavity and the manifold as it is rotated. | 11-05-2009 |
