Description
(54) ФОРМА ДЛЯ ИЗГОТОВЛЕНИЯ ИЗДЕЛИЙ ИЗ ТЕРМОПЛАСТОВ(54) FORM FOR PRODUCTION OF THERMOPLAST PRODUCTS
1one
Изобретение относитс к переработке термопластов . и гложет быть использовано дл изготовлени изделий в этажных формах методом лить под давлением .The invention relates to the processing of thermoplastics. and it is used to make products under pressure using the method of injection molding.
Наиболее близкой к предлагаемой вл етс литьева форма дл изготовлени изделий из термопластов, содержаща подвижные и неподвижные плиты матриц, подвижную плиту пуансонов, неподвижные направл ющие колонки со втулками, выталкиватели литников, литниковые втулки, выполненные с поперечным сечением развод щего литника ступенчато уменьшающимс по направлению от входа во втулку на величину равную или превышающую суммарную величину поперечного сечени расположенных в ней впускных литников, направленных под углом по ходу заливки по отношению к развод щему литнику, и т ги - задержкиГ13.Closest to the present invention is a casting mold for the manufacture of thermoplastic products, containing movable and fixed matrix plates, a movable plate of punches, fixed guide columns with bushings, gate ejectors, sprues made with a cross section of the spacing sprue stepwise decreasing from the entrance to the sleeve by an amount equal to or greater than the total value of the cross-section of the inlet sprues located in it, directed at an angle along the fill direction along respect to the present diluted sprues and thrust - zaderzhkiG13.
Недостатком известной формь) вл етс возможность зависани изделийThe disadvantage of the known form) is the possibility of hanging products
на пуансоне из-за образовани облойной пленки между выступами литниковой втулки и плитой пуансонов.on the punch due to the formation of a layer film between the protrusions of the sprue bushing and the plate of the punches.
Цель изобретени - повышение эксплуатационной надежности этажной формы путем предотвращени залипани изделий на пуансоне.The purpose of the invention is to increase the operational reliability of the floor form by preventing the products from sticking on the punch.
Поставленна цель достигаетс тем что форма дл изготовлени изделий из термопластов, содержаща подвиж10 ные и неподвижные плиты матриц, подвижную плиту пуансонов, неподвижные направл ющие колонки со втулками, выталкиватели литников, литниковые втулки, выполненные с поперечным, This goal is achieved by the fact that the form for the manufacture of products from thermoplastics, containing movable and fixed matrix plates, movable plate of punches, fixed guide columns with bushings, gate ejectors, sprues made with transverse,
15 сечением развод щего литника ступенчато уменьшающимс по направлению от входа во втулку на величину равную или превышающую суммарную величину поперечного сечени расположенных в 15 by the cross section of the diverting gate stepped decreasing in the direction from the entrance to the sleeve by an amount equal to or greater than the total value of the cross section located in
