Abstract: The present invention provides a melter that can improve melting efficiency compared to prior arts and an injection apparatus with improved injection efficiency. A melter according to the present invention includes a through hole, one opening of the through hole is an inflow port and the other opening is an outflow port, an inner wall surface of the through hole is formed of an inclined surface so that the opening becomes narrower from the inflow port to the outflow port of the through hole, an opening width of the inflow port is 4.1 mm to 10 mm and an opening width of the outflow port is 1.0 mm to 4.5 mm.

Abstract: It is an object of the present invention to provide a resin molded body capable of appropriately and easily improving strength compared to the prior art. The resin molded body according to the present invention includes first phases (21, 24) in which convex and concave parts extend in substantially linear directions (D, E), observed within a measurement range (A) of 5 ?m×5 ?m arbitrarily selected on a resin cross section and the first phases account for 50% or more. The first phases are preferably in a crystalline state. A second phase made of an amorphous substance (25) is preferably interposed between the first phases.

Abstract: The present invention provides a connection structure and a manufacturing method therefor capable of increasing reliability of a connection part compared to the prior arts. A connection structure according to the present invention includes a plurality of conductive members, a connection part that electrically connects the conductive members, and an electrically insulating molded body in which the connection part is embedded. It is thereby possible to physically reinforce the connection part of the conductive members, keep the connection part in a hermetically sealed condition, thereby prevent corrosion and increase reliability compared to the prior arts.

Abstract: An injection device in a molding machine includes: a cylinder having an outlet member formed at a tip-end injection side, a stopper part provided at a rear side, and a pellet supply opening for supplying plastic pellets; a melting device having a plurality of melting holes formed communicating from inflow-side large openings to outflow-side small openings in the longitudinal direction of a device main body, the melting device having a diameter equal to an inner diameter of the cylinder; a heating unit for heating the melting device; and a drive unit for causing the melting device to move in a reciprocating manner.

Abstract: A first protrusion member 12 is provided on two side surfaces of a fixed mold 1 having a first parting surface 11. Moreover, a second protrusion member 22 is provided on side surfaces of a moving mold 2 including a second parting surface 21 having the same shape and size as the first parting surface 11, that is, two side surfaces placed in positions which are not opposed to the first protrusion member 12 when the fixed mold 1 and the moving mold 2 are closed. Consequently, the fixed mold 1 and the moving mold 2 are positioned by fitting the first protrusion member 12 into the side surface of the moving mold 2 and fitting the second protrusion member 22 into the side surface of the fixed mold 1. Consequently, it is not necessary to provide a guide pin in order to carry out the positioning and a size of a device can be reduced correspondingly.

Abstract: A first fitting surface 11 and a first mating surface 12 taking a concave shape are formed on a fixed mold 1, a second fitting surface 21 to be fitted to the first fitting surface 11 in clamping and a second mating surface 22 taking a convex shape which is to be mated in the first mating surface 12 in the clamping are formed in a moving mold 2, and a concave portion is provided on a bottom surface of the first mating surface 12 to form a cavity 3. Consequently, the fixed mold 1 and the moving mold 2 are positioned by fitting the first fitting surface 11 and the second fitting surface 21 and mating the first mating surface 12 and the second mating surface 22. Consequently, it is not necessary to provide a guide pin in order to carry out the positioning and a size of a device can be reduced correspondingly. Moreover, it is possible to decrease heat capacities of the fixed mold 1 and the moving mold 2 by the reduction in the size, thereby decreasing consumed power required for a temperature control.

Abstract: A injection device in molding machine is capable of efficiently heating and melting a plurality of charged pellets in a short period of time, and injecting a melting resin with superior quality. The injection device has a cylinder including a pellet supply port, a plunger, a driving unit, a melting instrument with a plurality of melting holes, which are cone-shaped passages, formed in a cylinder-shaped instrument body to communicate from inflow-side large openings to outflow-side small openings, a nozzle provided on an injection side of the cylinder and a heating unit heating the melting instrument. A diameter of the tip-end of the plunger is set to be the same as a diameter of the outflow side face of the melting machine.
