Abstract
The invention relates to a U-shaped pipe fitting injection molding mold, which is mainly used for a U-shaped plastic product with curve and camber. The mold is common in the fields such as automobileintake manifolds, industrial instruments and meters, connecting bends of plastic building materials and the like. The heights of two bellmouths of product corresponding to the U-shaped pipe fitting injection molding mold are at the same position, and the assembly dimension is smaller. The conventional rotary type core scheme cannot make the product rotated out because of small space. The U-shapedpipe fitting injection molding mold adopts a rib ring structure, uses an injection molding machine, firstly looses a bent core straight line through a double core, and then pushes out the bent core, so that the bent core is separated from a mold cavity, a rib ring is driven to rotate through a gear rack of an oil cylinder, the bent core does not move, and the rib ring is pushed from the end face of the product to make the product separated from the bent core to complete the core loosening motion of the mold.
Description
Technical field
U type pipe fitting injection molding mold of the present invention relates to building water supply and drainage plastic pipe injection mold.
Background technology
The fast development of plastics industry and great demand have also been brought challenge when bringing opportunity for Chinese mould enterprise.The core means that mould is made as industry to product quality, kind, output, and even play a part very importantly on the cost, the height of mould design and manufacturing technology has directly reflected the ability of designing and developing and the manufacturing industry level of country.Exploitation has the mould of autonomous core technology, precision, complexity and specific use to improve China's plastic moulds technology level, to promote the die industry development; in industrial products; people usually can require the product with bending shape in the tools such as camber, arc such as U type; as the most common in fields such as automotive air intake arm, industrial instrumentation instrument, materials for construction connecting bends; this series products is special because of shape; its mould structure and stripping means complexity, manufacture difficulty is big, and the production cycle is long.The design and fabrication of its core-pulling mechanism becomes the key of Mold Making.
Summary of the invention
The pairing product two bellmouth height of U type pipe fitting injection molding mold are on same position, and installation dimension is shorter, adopt the scheme of rotating core, because the space is little, can't screw out product; Utilize injection machine, eject core and product and drive the gilled rings rotation, make product break away from curved core by the oil cylinder rack-and-pinion.
U type pipe fitting injection molding mold is by solid plate, moving platen, and swing pinion, gilled rings, carrier gear, tooth bar, oil cylinder, the duplex core, curved core, panel, base plate, back-up block, push pedal, the ejector pin retaining plate main parts size is formed.
U type pipe fitting injection molding mold is loosed core and is gone into the core scheme, the utilization three-dimensional software, and the action of simulation suction core is to the action carrying out of suction core structural optimization and design
Curved design of Cooling System of loosing core in the U type pipe fitting injection molding mold.The design and the manufacture difficulty of interior curved core cooling water channel are big, bad again sealing, and cooling water channel adopts rotation electrode processing.
The safety Design of U type pipe fitting injection molding mold motion.Each action of loosing core is carried out in order, and safe locating device is accurately arranged, and relevant anti-drop device and reliable precision guarantee the security of motion.
Beneficial effect
U type pipe fitting injection molding mold satisfy every profession and trade to the demand of special shape plastic product, improve complicated die the production domesticization degree, reduce dependence to the high-grade mould of import, promotion China to the transition of world's mould power, promotes the technological progress of China's mould from world's mould big country.
