It includes a hot-runner plate, a hot-runner distribution block adjacent to the hot-runner plate, and a plurality of hot-runner nozzles. The hot-runner distribution block is a monolithic seamless metal block. A lower die plate is removably attached to the hot-runner plate, and an upper die bolster is adjustably attached to the lower die plate and is movable along fixed guide columns. The upper die bolster comprises a base plate, a stripping plate and a slide plate. A plurality of form cores are supported on the upper die bolster, and a plurality of annular stamps are attached to the lower die plate, each being around a form core and each having a conical exterior surface tapered towards the lower die plate, and cooperating with a die; a plurality of dies is carried by the lower die plate, and each has a mating conical surface for receiving the conical surface of a stamp in close fit therewith when the molding tool is closed. The hot-runner distribution block has at least two channels for receiving two different material components from injectors, the channels comprising main channels and branch channels of equal length between their inlets and outlets, and there is a temperature stabilizing construction in the hot-runner distribution block and the hot-runner nozzles. A fluid operated valve is provided for selectively releasing to a nozzle, or for blocking, the different material components.

    摘要: Apparatus for the simultaneous production of preforms consisting of polyethylene terephthalate (PET) fed and distributed to a plurality of cavities. In order to reduce the occurrence of acetaldehyde formation in a cavity, for example, a heated distributor block used in the production of preforms of the PET material, the material flowing through a channel is subjected to additional turbulence. To this end, an element, preferably of metal, is installed in the channels, such element being provided with sets of radial spokes which are azimuthally offset in relation to each other in the axial direction. Besides inducing turbulence, such spokes act as homogenizing elements serving to diffuse heat over the cross section of the flowing process material.

    摘要: A nozzle for injecting a moldable material has a nozzle body which defines a nozzle channel leading to the nozzle outlet. The nozzle outlet is controlled by an axially slidable nozzle pin extending coaxially through the nozzle channel. A guide sleeve slidably supports the nozzle pin until it reaches the region adjacent the nozzle outlet. As a result, the length along which the nozzle pin is exposed to the moldable material is significantly reduced, thereby substantially eliminating the bending stresses applied to the nozzle pin by the pressure asymmetries in the incoming moldable material. The nozzle pin may also be retracted fully within the guide sleeve to provide an unobstructed path for the moldable material to flow through and consolidate as it approaches the nozzle outlet. With this arrangement, the incoming moldable material may be conveyed towards the nozzle channel asymmetrically with respect to the axis of the nozzle pin without any deleterious effect.

    摘要翻译: 用于注射可模制材料的喷嘴具有限定通向喷嘴出口的喷嘴通道的喷嘴体。 喷嘴出口由通过喷嘴通道同轴地延伸的可轴向滑动的喷嘴销控制。 引导套筒可滑动地支撑喷嘴销,直到其到达喷嘴出口附近的区域。 结果,喷嘴销暴露于可模制材料的长度显着减小,从而基本上消除了通过进入的可模制材料中的压力不对称性而施加到喷嘴销的弯曲应力。 喷嘴销也可以完全缩回到导向套筒内,以提供一个无阻碍的路径,以使可模制材料在接近喷嘴出口时流过并固结。 通过这种布置,可以相对于喷嘴销的轴线不可移动地将输入的可成型材料朝向喷嘴通道输送,而没有任何有害的影响。

    摘要: The hot-runner coinjection distributor block arrangement comprises several block parts (6, 7) which with the help of heating elements (8) may be brought to differing temperatures. These block parts (6, 7) are spaced from one another with an intermediate piece (9) and are supported via a support element (10) on the head plate (2). In this support element (10) spring elements, preferably a disc spring (11) is incorporated, which spaces the support element (10) from the head plate (2) and press the two block parts (6, 7) onto one another also in the cold mode. In the hot mode these disc springs (11) permit an axial expansion of the block parts (6, 7) and reduce the tension force exerted onto the support element (10). Peg-like formations of the intermediate piece (9) and of the support element (10) ensure that the bores for the guiding of the closure needle or of the feed channel (13) by the thermal expansion of the block parts (6, 7) are retained, i.e. are not laterally displaced.

    摘要: The method is used to process a synthetic moulding compound which crystallizes within a specific temperature range. In order to prevent milkiness in the blank to be produced, the moulding compound is chilled. The method prevents such milkiness, at least in the gate area of the blank, by keeping all of the moulding compound, during the operating cycle, as far as the gate area, at a temperature which is above the temperature T.sub.CC below which the moulding compound begins to crystallize. A gate system, which may be used to carry out the method, uses, in the interior of the injection nozzle, a strongly heat conducting nozzle core, a strongly heat conducting area in the immediate vicinity of the gate opening, and a gap for heat insulation of the nozzle tip, the nozzle core and the moulded body.
