    • PROBLEM TO BE SOLVED: To provide a compression-molding method capable of enhancing an yield of a product by preventing wear debris generated by dragging from being included.
      SOLUTION: The compression-molding method comprises the steps of making a slide disk 3d connected via a spring 3c to a movable plate on the movable mold side contact a parting surface of the fixed mold 2 by spring force, a fixed mold 2 being arranged to face a movable mold 3; and compression-molding a resin R filled in the cavity with a core 3g by injecting the resin into a cavity of the mold and then advancing the movable mold 3 to penetrate the slide disk 3d, wherein a resin film F is placed between the fixed mold 2 and the slide disk 3d and the one surface of the resin R in the cavity 4 is compressed via the film F.

    • PURPOSE:To obtain an outsert molding having a rotary function or rocking function without the use of an exclusive gate for rotary function or rocking function by providing a tunnel gate or side gate integrated with a subrunner. CONSTITUTION:A tunnel gate 18 or side gate through which resin is packed into a rotary function part 16 is provided integrally with the subrunner 14 of an outsert mold. A resin injected is packed through a gate 15 into a fixed resin molding section 13 and the subrunner 14 and also into a rotary function part 16 through the tunnel gate 18. After the packing is ended, pressure keeping, cooling and mold opening are made, and at a time when a product is finally ejected from the mold, the tunnel gate 18 is separated from the rotary function part 16. The rotary function part 16 becomes turnable and thereby an outsert molding having the rotary function part 16 can be obtained.
    • 目的:为了获得具有旋转功能或摇摆功能的外插式成型件,不需要使用专门的旋转功能或摇摆功能,通过提供与冲击器一体化的隧道门或侧门。 构成:与外插模具的辅助器14一体地设置有隧道门18或侧门,树脂被包装到旋转功能部件16中。 注入的树脂通过浇口15被填充到固定树脂模制部分13和补充器14中,并且还通过隧道浇口18进入旋转功能部分16.填充结束之后,进行压力保持,冷却和开模, 并且在产品最终从模具中排出时,隧道门18与旋转功能部分16分离。旋转功能部件16变为可转动,从而可获得具有旋转功能部件16的外插模制件。

    • PURPOSE:To obtain a synthetic resin made ball valve of an excellent quality and property at a low cost, by injecting resin in the cavity shaped by the ball plug with a spindle, the seal ring having a relief groove on a sliding face and the core body provided with a seal holder, etc. CONSTITUTION:The cavity 20 of the shape of a valve body is shaped by putting the beforehand prepared ball plug 2 with a spindle 5, the seal ring 6 provided with a peripheral relief groove 7 on the sliding face 6a contacting the ball plug 2 and the core body 15a having the ring like seal holder 15c protruding to an axial direction in the internal space shaped by bottom and top forces 12, 14. The injection of resin is performed, contacting the seal holder 15c to the back of the seal ring 6. Because a part of the compression force due to a resin pressure is absorbed by the relief groove 7 by this, there is not essentially the possibility that the seal ring 6 is plastically deformed, then the valve body having an excellent sealing function is obtained.
    • 目的:为了以低成本获得质量优良的合成树脂制球阀,通过用主轴将由球塞形成的空腔注入树脂,密封环在滑动面上具有释放槽,并且芯体 本体设置有密封保持器等。构成:通过将预先准备的球塞2放置在心轴5上,形成阀体形状的腔20,密封环6在滑动件上设置有周边释放槽7 与球塞2接触的表面6a和具有环形密封保持器15c的芯体15a,该环形密封保持件15c在由底部和顶部力12,14形成的内部空间中沿轴向突出。执行树脂的注入,接触密封保持器15c 由于由于树脂压力的一部分压缩力被释放槽7吸收,所以密封环6基本上不会塑性变形,然后阀体 有了 获得了良好的密封功能。
