Title: Method for finishing internal surface of concrete pipe and device
Inventor: KOYAMA TAKEKI
IPC: B28B21/30
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To smoothen the internal surface of a concrete pipe continuously so as to be capable of confirming the finishing condition of the same by a method wherein a mold frame is rotated and internal surface finishing rollers, inserted into the internal part of the pipe, are moved up-and-down while the up-and-down movement is stopped when the value of a load, applied on the internal surface finishing rollers upon contacting with the internal surface of the concrete pipe, has become lower than the initial load and a constant value. SOLUTION: In the finishing of the internal surface of a concrete pipe, internal surface finishing rollers 2 are inserted from one end of a mold frame main body 10 through a roller driving main body 3. The recessed part 18 of the roller 2 is attached to the retaining shaft 15 of an assisting part 4 for retaining the rollers so that the rollers 2 are contacted with the internal surface of the concrete pipe in the mold frame main body 10. The internal surface is finished by rotating the mold frame main body 10 and the internal surface finishing rollers 2 into the same direction with different rotating forces. The rollers 2 are moved up-and-down by the up-and-down driving unit 5 of the rollers 2.  The up-and-down movement of the rollers 2 and the rotation of the mold frame main body 10 are stopped when a load, applied on the rollers 2 upon contacting with the surface of concrete, has become lower than an initial load and a constant load value.

IPC: B29C45/00
Filed: 1980-02-29
Abstract: PURPOSE: To obtain a molded article having little residual internal strain and a smooth surface and being fitted for an optical components and the like by giving pressure to the resin filled up inside a metal mold while a nozzle is left touched and thereby making the internal pressure of the filled resin be released to the side of an injection cylinder from a gate.  
     CONSTITUTION: After metal dies 1 and 3 are closed by a die-tightening plate 5 and a plunger 6 is set at a position of recession, the nozzle of an injection device 15 is touched to the gate of the metal die 1 and thereby melted resin is injected. When filling of the resin is completed, a hydraulic cylinder 11 is operated while the nozzle of the injection device 15 being left touched and pressure is given to the filled resin 16 before setting by the plunger 6. The output of the hydraulic cylinder 7 being about 1/10W1/20 of die-tightening force is sufficient on the occasion, while the extruding stroke of the plunger 6 is about 0.01W0.2mm conventionally. The internal pressure of the filled resin 1 to which pressure is given as mentioned above is released to the side of an injection cylinder 15a. The molded article, for instance, the optical component 14 molded under reduced internal pressure turns to be highly precise since the residual pressure which turns to be strain in removed.
