摘要:
A method of reducing fouling of a mold (12) caused by vulcanization of a rubber compound (14) in the mold (12). Pursuant to the method, about .2-20 phr of a fouling inhibitor composition comprising starch is added to the rubber compound (14) before it is vulcanized in the mold (12). The fouling inhibitor composition is substantially free of cross-linked fatty acids, asphalt, tackifying resins and synthetic plasticizers. More molding cycles can be run before the mold (12) is cleaned.
摘要:
Efficient and consistent processes for manufacturing moldings, especially ophthalmic lenses such as contact lenses. The processes comprise a series of improvements, including improvements in the areas of conditions for dispensing liquid prepolymer into lens molds, male and female mold mating, reusable molds, mold cleaning, lens separation from molds (demolding), lens handling, and in-line inspection. Cyclic series of processing steps are also disclosed. Additionally, an improved molding tool is disclosed, with the molding tool including a male mold housing and a female mold housing, each of which has disposed therein a plurality of mold halves.
摘要:
A moldable compound of the type which has the inherent capability of cleaning contaminating stains and residues in compression, transfer and similar molds, is deposited on a carrier sheet to form an uncured mat for placement in a mold to be cleaned. When placed in a mold to be cleaned and subjected to a molding operation, the moldable compound coating of the uncured mat will melt and flow into conformity with the interior configuration of the mold and cure in that conforming configuration. The cured mat is then capable of being ejected in as a reinforced unitary structure from the mold.

An automatic apparatus for in-line cleaning of moulds for tyres comprises a nozzle (2) suitable for sending a cleaning jet onto the moulds (1a, 1b), and a manipulator robot (22) able to guide the nozzle (2) for cleaning the moulds (1a, 1b) according to the tread pattern and according to images of the moulds (1a, 1b) supplied by detecting means (10).
摘要:
Invention is a cleaning robot for cleaning the inner surfaces (5) of the half mold (4) of tire curing molds comprising a basket (10) wherein a lifting arm (50) placed in a manner pivotal on a proximal end (52), the lifting arm (50) pivoted on a distal end (54) of a support arm (70). The cleaning robot fits completely into the basket (10) when the positioned as close and comprising a movable head (80) having a nozzle (82) coupled in a manner to establish fluid communication to the dry ice inlet (84) and located at the distal end (76) of the support arm (70) and a free end which is configured movably closer to the inner surface (5) such as at a vicinity of the inner surface (5) along the contour of its when the positioned as open.
摘要:
The invention is a cleaning method for the production of vehicle tire full-molds having profile. The method as the subject of the invention comprising the process steps respectively, the contaminated full-mold (1) is taken a pre-treatment with an ultrasonic cleaning apparatus (10), depurated full-mold (2) is re-cleaned by putting to dry ice process in a first cleaning station (20), cleaning of the full-mold with preferably multiple number of ultrasonic devices (51, 52, 53) by immersing into a cleaning liquid (50) in a second cleaning station (40), rinsing by taken in to a rinsing station (60), putting to another process by taken in to a passivation station (70), and drying by taken in to a drying station (80).
摘要:
Invention is a cleaning assembly for cleaning a tire curing mould comprising a turntable (20) mounted on a base plate (12); a cleaning arm (50) extending on the turntable (20) in a movable manner and configured to blow dry ice, and an insulation hood (60) surrounding the cleaning arm (50) wherein the base plate (12) is having an adapter support (16) configured to be gradually widen or narrow for being adapted to the insulation hoods with different diameters on the base plate.
摘要:
The invention provides a carriage (1) standing a base (4) thereon; and the base (4) attached to a lifting arm (10) via an upper pivot (11); a basket (50) rotatably hinged manner a transport mechanism comprising a holder part (30) for the tyre molds cleaning device. Transport mechanism comprises intermediate arm (20), extending in order to assembly distal end (12) of the lifting arm (10) and holder part (30) pivoted at one end of its to the holder part (30) from the other end to the distal end (12).
