摘要： A locally pressurizing type injection molding machine includes a stationary die and a movable die. An ejector pin extends through the movable die, with its tip end facing a mold cavity and its trailing end fixed by an ejector plate. A vibrating/pressurizing pin extends through the movable die and the ejector plate, with its tip end facing a resin passage and with its trailing end fixed by the vibrating/pressurizing plate. A vibrating/pressurizing actuator is disposed in rear of the vibrating/pressurizing plate, so that the vibrating/pressurizing can be effected through the vibrating/pressurizing plate, and the ejector pin can be advanced through the vibrating/pressurizing plate and the ejector plate, both by operation of the vibrating/pressurizing actuator.

摘要： A locally pressing type injection molding machine which performs various working operations on a molded product during an injection molding cycle is designed so that it can perform various working operation on a molded product after the injection step. To achieve this, a pressing pin is provided to extend in such a manner that it passes through at least part of either the fixed mold or the movable mold. A distal end of the pressing pin is provided in such a manner that it can advance into or retract from a cavity. A pressing cylinder is disposed behind the pressing pin to vibrate the pressing pin when a hydraulic pressure supply means supplies a pulsating hydraulic pressure to the pressing cylinder. A pulsating pressing force is applied to a resin which fills the cavity to work the molded product in a desired form. Therefore, a highly accurate worked surface can be obtained.

摘要： A machining chamber encloses a glass molding apparatus including a molding die assembly composed of upper and lower molding dies cooperating to define a mold therebetween. The glass molding apparatus, contained within the sealed machining chamber, further includes a clamping/heating/compressing station, a cooling station and a preform-loading/molding-ejecting station. A shutter is provided in the casing for selectively opening the casing to the ambient atmosphere. An annular nozzle surrounds a molding surface provided on one of the upper and lower molding dies and is used to supply a first inactive-gas to the region between the two dies. A second, independent inactive-gas supply provides inactive-gas directly into the sealed casing, whereby the region between the dies is maintained at a lower oxygen level than that within the remainder of the sealed casing.

摘要： A molding die assembly includes an upper molding die and a lower molding die facing the upper molding die with provision for their alignment. The upper molding die includes an upper core, while the lower molding die includes a hollow cylinder and a lower core. The upper core has one of the molding surfaces that corresponds to a molding, while the lower core has the other molding surface corresponding to the molding. The lower core slides in the cylinder and defines a cavity in cooperation with the upper core. A clamping device applies a clamping force to the upper molding die and the lower molding die, and a compression device applies a compressive force between the upper core and the lower core. The clamping force is generated between the upper molding die and the lower molding die but not between the upper core and the lower core so that no clamping force is applied to the preform. Hence, if the upper platen and the lower platen are not parallel or if the volume of the preforms varies, surface accuracy and shape accuracy of the molding are still achieved.
摘要翻译：成型模具组件包括上成型模具和面向上成型模具的下成形模具，用于对准。上模具包括上芯，而下成型模具包括中空圆筒和下芯。上芯具有对应于模制件的一个模制表面，而下芯具有对应于模制件的另一模制表面。下芯在气缸中滑动并且与上芯配合定义一个空腔。夹紧装置将夹紧力施加到上部模具和下部模具，并且压缩装置在上部芯部和下部芯部之间施加压缩力。在上模具和下模具之间产生夹紧力，而不是在上芯和下芯之间产生夹紧力，使得预型件不施加夹紧力。因此，如果上压板和下压板不平行，或者如果预制件的体积变化，则仍能实现模制品的表面精度和形状精度。

摘要： A glass compression molding apparatus includes a horizontal upper platen and a lower platen disposed parallel to the upper platen. A top die is mounted for movement along the upper platen between a plurality of stations, and a bottom die is mounted for movement along the lower platen between another plurality of stations. A preform is introduced into the bottom die and then heated and compressed to form a molded product. The molded product is annealed and then removed from the bottom die. A clamping device forces the upper and lower platens together. A compression device compresses the preform. A conveying device moves at least the bottom die while suspended above the lower platen. Thus, wear of the lower platen, which would otherwise result from the sliding of the bottom die on the lower platen or the entry of foreign matter between the bottom die and the lower platen, is avoided. Such a wear or entry of foreign matter would occur while the mold is moved between stations in the conventional apparatus. Therefore, the alignment of the mold can be maintained, and the dimensional accuracy of the product can be improved.
摘要翻译：玻璃压缩成型设备包括平行于上压板设置的水平上压板和下压板。安装顶模以沿着多个台之间的上压板运动，并且安装底模以沿着另一多个工位之间的下压板运动。将预制件引入底模中，然后加热并压缩以形成模制产品。将模制产品退火，然后从底模移除。夹紧装置将上部和下部压板压在一起。压缩装置压缩预制件。输送装置至少移动底模，同时悬挂在下压板上方。因此，避免了下压板的磨损，否则这将导致底模在下压板上的滑动或异物进入底模和下压板之间。在常规设备中的模具在站之间移动时，会发生异物的这种磨损或进入。因此，可以保持模具的对准，并且可以提高产品的尺寸精度。

The apparatus is further provided with first advancing mechanism for advancing the first local pressurizing pin, second advancing mechanism for advancing the second local pressurizing pint and a device for individually setting the points in time at which advancing movements of the first local pressurizing pin and the second local pressurizing pin are started and for individually setting the pressurizing pressures given by the first local pressurizing pin and the second local pressurizing pin. One processing action is given to a molded product by advancing the first local pressurizing pin while another processing action is given to the molded product by advancing the second local pressurizing pin. Accordingly, in the case where two or more kinds of processing operations are performed, the processing operations can be started at different points in time and can be effected with different pressures.
