Patent number: 8827675Abstract: A mold assembly includes a product cavity for producing an insert-molded product and a projection-forming cavity for, if an insert of the product is irregularly deformed or disposed in wrong orientation, forming a projection on the insert-molded product. The projection, if present on the product, blocks most of the light emitted from a light-emitting element. A photodetector detects the intensity of the received light and when the detected light intensity is less than a predetermined value due to the presence of the projection, the product is judged to be rejected. Visual inspection or optical sensors judge the product to be rejected if the product has a through-hole closed and to be acceptable if the through-hole of the product is open. This judgment does not require an X-ray inspection device or radiologists.Type: GrantFiled: March 29, 2012Date of Patent: September 9, 2014Assignee: Nissei Plastic Industrial Co., Ltd.Inventors: Minoru Yamazaki, Tetsuo Kurasawa

Publication number: 20140196807Abstract: An injecting machine for two different liquids is configured to inject a liquid mixture of the two different liquids in a first-in first-out manner. The liquid mixture passes from a passage of an injection cylinder through a helical groove of a plunger into a forward space formed forwardly of the plunger as the plunger gradually moves back. When the plunger reaches a fully retracted position, a first part of the mixture remains in a front portion of the forward space while a last part of the mixture remains in a rear portion of the forward space. As the plunger moves to an advanced position, the first part of the mixture is first injected out of a nozzle and the last part of the mixture is finally injected out of the nozzle.Type: ApplicationFiled: January 13, 2014Publication date: July 17, 2014Applicant: NISSEI PLASTIC INDUSTRIAL CO., LTD.Inventor: Toru IKEDA

Publication number: 20130309350Abstract: An injection molding apparatus includes, as its drive sources, an electric power supply source, compressed air source and hydraulic pressure supply source. A hydraulic-pressure-supply-destination selection section supplies hydraulic pressure from the hydraulic pressure supply source to a selected one of first and second mold clamping cylinders. Necessary capacity of the hydraulic pressure supply source can be lowered as compared to a case where all of the mold clamping mechanisms and injecting machines are driven by hydraulic pressure. Because only a selected one of the mold clamping mechanisms is driven at a time, the necessary capacity of the hydraulic pressure supply source can be halved as compared to a case where the mold clamping mechanisms are driven simultaneously.Type: ApplicationFiled: May 9, 2013Publication date: November 21, 2013Applicant: Nissei Plastic Industrial Co., Ltd.Inventors: Toru IKEDA, Hiroo OKUBO, Akira OBINATA
