Upon threading by the piercing method, the force field of the reinforcing fibres is not interrupted, and the thread itself is compacted due to the increased fibre content.EFFECT: strength of the thread formed in puncturing hole is much higher than the strength of the thread cut by the traditional method.1 cl, 1 tbl, 3 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 680 513 C1 (51) МПК B29D 1/00 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК B29D 1/00 (2018.08) (21)(22) Заявка: 2018103596, 30.01.2018 (24) Дата начала отсчета срока действия патента: Дата регистрации: (73) Патентообладатель(и): Акционерное общество "Авангард" (АО "Авангард") (RU) 21.02.2019 (56) Список документов, цитированных в отчете о поиске: SU 377245 A1, 17.04.1973.

Non-motorized screw product take-out mold

The present invention relates to a non-powered screw product taking out mold. The non-powered screw product taking out mold of the present invention is a mold for taking out screw products (101) by allowing a fixed mold and a moving mold which are mounted on an injection machine to be mutually combined with or separated from each other. The fixed mold is comprised of a first plate (110) which fixes a worm shaft gear (111), and second to fourth plates (120-140) which are interlocked with the moving mold such that the second to fourth plates are mutually integrally separated from the first plate (110) or get closer to the first plate (110). The moving mold is comprised of a fifth plate (150) which forms a parting surface (P) with the fourth plate (140) and takes out the screw products (101), and sixth to ninth plates (160-190) which ascend or descend the fifth plate (150). The second to fourth plates (120-140) have a plurality of screw cores (141) embedded therein, which include a forming protrusion for forming a screw thread on the screw products (101) such that the forming protrusion is inserted into a cavity and has a core gear (131) mounted thereon. The core gear (131) is constructed to have a worm wheel gear (132) externally engaged therewith such that the screw cores (141) are rotated without electric power, wherein the worm wheel gear (132) has the worm shaft gear (111) internally engaged therewith and thus, the worm wheel gear (132) is rotationally operated when the second to fourth plates (120-140) are separated from the worm shaft gear (111) or get closer to the worm shaft gear (111). According to the present invention, the non-powered screw product taking out mold improves maintenance by significantly simplifying structure of the injection machine, and particularly can reduce labor cost and process time by skipping a separate sorting operation since a robot arm for removing a runner by promoting utilization of space can be used.

Attachment assembly

ABSTRACT OF THE DISCLOSURE An attachment assembly includes an anchoring rod and a body of plastics material which can be fused or melted by heat. To secure the anchoring rod in a borehole, initially the body of plastics material is inserted and then the anchoring member is heated and driven into the body of plastics material. The heat changes the character of the plastics material so that it secures the anchoring member within the borehole. The body of plastics material is formed of granules. The granules can be in loose form within a destructible container or envelope or they can be secured or bonded together so that the body is a unitary member.

METHOD FOR FIXING STRUCTURAL BODIES WITH A COMPOSITE MATERIAL OF GLASS MATRIX REINFORCED WITH FIBERS

Threaded fiber-reinforced plastic member and method of coating the same

A threaded member made of fiber-reinforced plastic (FRP) obtained by the present invention which is characterized by having at least the threaded portion coated with a crosslinked nylon resin. Accordingly, the surface of the threaded portion is smooth, exhibiting adequate elasticity and fitness, and exhibiting excellent screwing ability to enable the smooth meshing of a nut with a bolt without jolting. Moreover, the threaded member is also excellent in weathering resistance and chemical resistance.

Metal bolt with a composite core for enhancement

The improved metal matrix bolt has a metal shell having the bolt head, shank and threads thereon. The shell has a longitudinal space therein wherein a composite core of fibers is bonded. The fibers are divided into two groups: a longitudinal group and a spiral group. The spiral group wraps clockwise about the longitudinal group and is inclined at an angle of about 30° to 45° degrees from the axis of the bolt. The fibers are bonded within the space to the interior surface of the shell whereby when the bolt is torqued, the bolt has increased tensile strength and reduced thermal axial growth.

Plastic fastener for threaded blind aperture

The fastener, which is typically made of thermoformed or similar plastic, includes a shank portion at least two parallel fingers which further include a proximal end and a distal end. The proximal end of the fingers is integral with a base portion and the distal end of the fingers is integral with bridge elements which attach to a wedge element. A driving pin is attached to the base portion and is aligned with a gap formed between the at least two parallel fingers. The parallel fingers further include lateral serrated portions and radially oriented stabilizing fins. Upon impact to the driving pin when the fastener is placed into a blind threaded aperture, the wedge portion forces apart the distal ends of the parallel fingers, while the driving pin forces apart the proximal ends of the parallel fingers thereby driving the serrated portions of the fingers against the threads of the blind threaded aperture.

Plastics ball bearing nut - is injection moulded with accurately formed thread

The nut body is made from a single homogeneous plastics part in which the threads and ball return channel are made in one workstep by casting or injection moulding so that the thread grooves and ball return channel form a closed constantly curved race. The balls are added through bores opening into the return channel. These bores can be formed by a subsequent stock-removing process or at the same time during moulding. The hollow mould has a moulding core with round thread wrapped with an elastic or plastically deformable closed ring of round cross-section so that part of the ring cross-section fills up the negative thread and the other outwardly pointing part of the core forms the grooves for the nut. ADVANTAGE - Economical mass prodn.

Fiber reinforced composite treaded member

FIBER REINFORCED COMPOSITE THREADED MEMBER ABSTRACT A threaded member including a core, a thread-defining element helically extending around and along the core and a reinforcing tubular fabric layer bonded to the exterior surface of the combined core and thread-defining element. The radial projection of the thread-defining element defines a helical thread whose contour is followed by the fabric layer and the exterior surface of the threaded member. The composite threaded member may be formed by forming a braided or knit fabric layer on an elongated spiral wrapped core. The spiral wrapped thread-defining element and the fabric reinforcing layer is bonded to the core. A polymer sheath protects the underlying structure.
