In a molded product, at least an opening end, forming a window frame of a window formed as a part of a molded subassembly, is fastened integrally to a skin of the molded subassembly. Alternatively, a decorative component part is disposed on an outer periphery of the window so that a parting line between the decorative component part and the skin is visible as being joined closely in a decorative surface of the completed molded product. Processes for manufacturing the same are disclosed as well.

Molded product and process for manufacturing the same

A method for forming tear lines in the rear side of an automobile interior article having a cover portion being developed from which an airbag inflates. When either an automobile interior article body having an integrally molded surface portion or an automobile interior article surface portion is to be molded, the mold is opened after tear line forming projections are moved forward and backward with the mold closed. Thus, the tear lines can be formed at the molding time without any visible extrusion marks of the tear line forming projections on the front surface side (the design face).

Method for manufacturing automobile interior article

A method of molding a hollow body to make the body nearly uniform in thickness around an internal opening thereof. A weir is provided in a central part of an opening portion of the mold cavity near an upstream side of the opening portion with respect to the direction of flow of a resin. Molten resin is injected into the cavity, and pressurized gas is thereafter injected into the molten resin in the cavity to make the internal opening in the resin. Since the weir is provided, the resin comes into uniform contact with the inner mold surface of the die at the opening portion as the resin flows into opening portion. The resin is uniformly cooled and solidified, starting with the inner surface and working inwardly, so that the hollow body is made nearly uniform in thickness around the internal opening.

Molded resin body and method for producing the same

A mold for hollow injection molding has an inlet for admitting a fluid into the molten resin when injected to form an interior hollow in the molded product. The inlet is opened and closed by retraction and advancement of a movable pin having at least a portion to fill the inlet and close it. When the inlet is closed, while the resin is being injected, the pin has a portion which projects out of the inlet into the space where the resin is injected. When the inlet is opened, the retraction of the pin leaves a short passageway in the injected resin leading from the fluid inlet for flow thereinto of the hollow-forming fluid. Preferably, the pin is stepped with an inlet-closing large rear portion and a smaller projecting forward portion which is located in and has an annular clearance with the inlet when it is open. The pin may be detachably connected to a movable plunger, operated by fluid or spring pressure, to enable replacement by pins of different lengths, sizes, etc.

Herein disclosed is a hose joint which comprises an outer tube having a threaded portion at one side of a flanged portion and a sleeved portion at the other side, and an inner tube arranged in the outer tube and having a nipple portion positioned in the sleeved portion and a tapered sealing portion for providing communication between the nipple portion and the threaded portion of the outer tube and for acting for a mating member to be jointed to the hose joint. Both the outer tube and the inner tube are made of a tubular material such that at least the flanged portion of the outer tube and the sealing portion of the inner tube are plastically deformed.

Hose joint

Herein disclosed is a hose midway holder which is formed into such a cylindrical shape as to be fixedly mounted on a hose. The hose midway holder comprises a flanged portion formed on the outer circumference thereof for being brought into abutment against the peripheral edge of a mounting hole of a mounting fixture, and a groove portion formed in the outer circumference thereof for receiving a fixing clip which is adapted to clamp the peripheral edge of the mounting hole of the mounting fixture together with the flanged portion. The hose midway holder is formed in the inner circumference thereof with a recessed portion and a communication port for providing communication between the former and the outside of the outer circumference of the hose midway holder.

Hose midway holder

The hose midway holder comprising: a tubular body adapted to be fixed on a hose; a flange adapted to abut against the peripheral edge of a mounting hole of a mounting fixture and formed, if necessary, at its outer peripheral face with at least one flattened face where it is fitted in the mounting hole of the mounting fixture; and a groove in which is to be fitted a fixing clip for clamping the peripheral edge of the mounting hole of the mounting fixture together with the flange. The hose midway holder itself is made of a pipe material and has at least its flange formed by plastic deformation.

A process for manufacturing a hose mouthpiece by joining a nipple having a radially outwardly spread end to a mouthpiece body having an axial nipple holding hole. The nipple is inserted into the hole in the body until its spread end abuts on a seat surface encircling one end of the hole. The spread end is press formed against the seat surface so that it may become flush with the seat surface, and a seat surface encircling the other end of the hole to define a seat for one end of a hose is caulked about the nipple projecting outwardly from the other end of the hole, whereby the nipple is secured to the mouthpiece body. The process is suitable for making, for example, a mouthpiece for a brake hose, and inexpensive, since it does not include welding or brazing.
