Provided is a sliding mechanism capable of moving a slider in at least two different directions with a simple structure. The sliding mechanism includes a guide body including a guide unit configured to guide a slider in predetermined directions; and the slider is guided by the guide unit to move in the predetermined directions. The predetermined directions at least include a first direction and a second direction which are different from each other, and the guide unit at least includes a first guide unit configured to guide the slider in the first direction and a second guide unit configured to guide the slider in the second direction.

A mold for injection molding of a plastic cap having protruding internal portions is provided. The mold has a male mold and a female mold that form a molding cavity. The male mold consists of a mobile portion fitted above a fixed portion, the mobile portion being rotatable around the fixed portion and provided with grooves having an inclined lateral surface that defines an outlet ramp. A method for producing a plastic cap by use of the mold is also provided. The method includes rotating the mobile portion of the male mold with respect to the plastic cap until flat walls of the mobile portion are located in the region of protruding portions of the plastic cap, thereby causing a slight circumferential expansion of the skirt of the plastic cap.

Provided is a molding method of a sealing cover, realized by setting up a sealing cover mold, the mold includes a cavity and a core group arranged in the cavity, including setting up a first core and a second core, the mold opening direction of the first core and the second core are not parallel. The present application does not need a process hole to perform the injection molding of the sealing cover with a fastening structure, whose sealing is also better.

A vehicle headliner includes a two-piece headliner body made up of first and second headliner pieces that are secured together in a mechanical joint. Each of the first and second headliner pieces is comprised of a molded polymer substrate having first and second sides and a fabric on the first side. The molded polymer substrate is partially impregnated into the fabric such that the fabric is fused to the first side. The first piece defines an opening for receipt of a console. There is at least one bridge that spans across the opening and has a molded-in attachment feature for securing the console.

A projection mechanism of a molding die configured to mold a molded article by a fixed-side die and a movable-side die, the projection mechanism including: a projection pin using a reaction force of a spring as a drive source; and a first spring and a second spring configured to project the projection pin, wherein the first spring has a maximum reaction force in a die clamping state, and projects the projection pin while gradually reducing the reaction force in a projection process, and the second spring projects the projection pin with a constant reaction force while projecting the projection pin from the die clamping state, where stop of movement of the second projection pin during the projection process causes compression of the second spring to increase the reaction force of the second spring, thereby energizing the projection pin to further project the projection pin.

A motion transmitting device comprising: a slider movable along a slider guide; and a connecting body movable along a connecting body guide, wherein the slider and the connecting body are disposed in contact with each other, each of the slider and the connecting body has a contact surface that is slidable, and the amount of displacement and/or the speed of displacement of an output end relative to an input end can be reduced or can be made equal to each other or increased through setting of the angle of a center axis line of the slider guide about a center axis line of the connecting body guide and/or the inclination angle of the contact surface.

A method of molding a product including an undercut part or a right-angle part includes providing a female mold, a first male mold and a temporary mold to form a first molding chamber, wherein a boundary between a core and a lifter of the first male mold is located outside the first molding chamber; performing a first injection into the first molding chamber to mold a first portion of the product including the undercut part or the right-angle part; removing the temporary mold; replacing the first male mold with a second male mold to form a second molding chamber, wherein a boundary between a core and a lifter of the second male mold is located outside the second molding chamber; and performing a second injection into the second molding chamber to mold a second portion of the product integrally formed with the first portion of the product.

A device for demolding negatives in thermoplastic injection molds includes an ejector which comprises an ejector profile for the fastening thereof to an ejector plate and a figure insert with a profile that is complementary to a piece to be molded. The ejector further comprises a flexible element arranged between the ejector profile and the figure insert which pushes the figure insert in order to demold the negative by an angular displacement and stretches the figure insert so as to return the ejector to the injection position thereof. The device eliminates the need for molding sliders which are costly as well as the need for a machining process for the installation thereof.
