Title: Method for judging shape of powder particle
Inventor: MATSUDAIRA KANJI
IPC: G01N15/02
Filed: 1998-05-13
Abstract: PROBLEM TO BE SOLVED: To judge the degree of estrangement from the spherical shape of a powder particle by using a sieve with a sieve mesh with essentially the same diameter as the particle diameter of a sample grain being obtained by the light-scattering method for sifting the sample grain and by obtaining the ratio below or above the sieve. SOLUTION: For one of two parts of a sample powder divided in advance so that the grain size is not maldistributed, the distribution of the grain size is measured by the light scattering method using a laser diffraction particle meter according to, for example, the wet method and a particle diameter X of a point where the ratio of the amount of integrated particle from the smaller or larger particle diameter reaches n% (for example, 50%) is obtained. Then, a sieve with the sieve mesh with essentially the same diameter as the particle diameter X is used for sifting the other of the divided sample grains, thus obtaining the ratio below or above the sieve. Then, based on the ratio below or above the sieve, the degree of estrangement is judged from the spherical shape of the sample grain.

Abstract: PURPOSE:To project efficiently ejector pins from a mold without damaging the ejector pins, by providing the ejector pins in a movable mold with spring mechanisms that reduce the resistance to the releasing of the mold when the mold is opened. CONSTITUTION:A molten resin is injected through a passage 6. After an injection molded item 5 is produced, as soon as return pins 9 are moves away from a stationary mold 1, the great repulsion of the springs 15 act on a first plate 7a so that the injection molded item 5 is moved a little away from the movable mold 2. As the stroke of the extension of the springs 15 is small, the injection molded item 5 is not fully released from the movable mold 2, but is drawn out from the stationary mold 1 together with the movable mold 2. When the movable mold 2 reaches near the end point of the stroke of the movement, an ejector rod 16 abuts on a second plate 7b, and pushes the second plate together with the first plate 7a toward the stationary mold 1. Then the ejector pins 10, 11 extend greatly from the movable mold 2 to eject the injection molded item 5.
