摘要： In an injection press molding machine of the present invention, a horizontal injection device (10) is disposed below a fixed die plate (2) of a vertical press device (1), the injection nozzle (10b) of its injection portion (10a) is bent in an L-shape and a valve (10c) for opening and closing a resin passage is disposed in this nozzle. A base (14) of a bed (4) supporting the horizontal injection device (10) slides with the injection nozzle (10b) as the center in accordance with thermal expansion and contraction of the horizontal injection device (10) and the L-shaped injection nozzle (10b) comes into contact with a lower mold (3) at a predetermined surface pressure. Therefore, color changeability of the resin and its purgeability are excellent and since a hot runner is not necessary, an economical and versatile mold can be obtained. Moreover, since the resin is packed using a short resin passage, molded articles having stable quality can be obtained. Even when the horizontal injection device (10) undergoes expansion and contraction, the lower mold (3) is not moved and resin leakage does not occur, either. Since the injection portion (10a) can move outward from below the fixed die plate (2), replacement and inspection of the injection nozzle (10b), the screw, and the like, can be made easily.

摘要： The present invention relates to an injection press device and a forming method therefor arranged such that a compression movement is performed after an injection when a moveable die is moved for compressing resin with respect to a fixed die. In particular, the structure is arranged in such a manner that the compression starting position is determined by mechanically positioning means and the position can be adjusted. Furthermore, the stroke deviation for the compression can be adjusted by detecting the position of the moveable plate during the compression stroke so that the levelness of the dies can be always maintained. Therefore, the parallelism of the die can be stably maintained against the injection pressure, and the levelness of the die can be maintained during the compression stroke. Therefore, the action of molten resin in the cavity is always stabilized at the time of the injection. As a result, stable quality resin product can be obtained.

摘要： This invention relates to an injection press machine and its molding method which effect a compression stroke after injection when the compression stroke of a movable mold is effected with respect to a fixed mold. More particularly, a compression start position is determined by mechanical positioning means, this position is adjustable and the position of the movable mold is detected during the compression stroke so that the stroke displacement for compression can be adjusted and a horizontal alignment between both molds can be always kept. Accordingly, parallelism of the molds can be held stably even the pressure by injection is applied to them and horizontal alignment of the molds can be kept during the compression stroke. Since the behaviour of a molten resin inside a cavity at the time of injection becomes always constant, resin molded articles having stable quality can be obtained.

摘要： This invention relates to a temperature controlling apparatus and its method for keeping constant a spigot gap of molds of a plastic compression molding machine, and controls the temperatures of structural components such as a bolster,a slide,frame,and the like,that affect the spigot gap of the molds so that their dimensional changes calculated from their dimensions and thermal expansion coefficients are below an allowable value of the spigot gap. Fluid passages are formed at least on the bolster for supporting the molds and on the slide, circulation means of an operation oil used for a lift cylinder is disposed in these fluid passages and temperature control means for attaining the control temperatures described above is disposed at the intermediate portion of the circulation means,so that the operation oil is circulated while being controlled to the set temperatures of the structural components. The temperature control means can be composed of a heat-exchanger and a flow rate regulating valve. According to this structure, a mold gap such as a shut height and a shear edge clearance can be controlled to a constant value,the change of clearance with each molding cycle is eliminated and stable molded articles can be produced.At the same time, molded articles having stable quality and free from molding change with time can be obtained.
摘要翻译：本发明涉及一种用于保持塑料压缩成型机的模具的插口间隙恒定的温度控制装置及其方法，并且控制诸如摇枕，滑块，框架等的结构部件的温度，其影响模具的插口间隙使得其尺寸和热膨胀系数计算的尺寸变化低于插口间隙的允许值。流体通道至少形成在用于支撑模具的垫板上，并且在滑动件上，用于提升缸的操作油的循环装置设置在这些流体通道中，并且用于获得上述控制温度的温度控制装置设置在循环装置的中间部分，使得操作油在被控制到结构部件的设定温度的同时循环。温度控制装置可以由热交换器和流量调节阀构成。根据该结构，可以将闭合高度，剪切边缘间隙等的模具间隙控制为一定值，消除每个成型周期的间隙变化，并且可以制造稳定的模制品。同时，可以获得质量稳定且成型不变的成型品随时间而变化。
