Abstract
The invention relates to an insert structure of a rear die for forming of hardware like connectors and relates to the field of forming die insert structures of hardware. The insert structure of the rear die for forming of the hardware like connectors solves the insert machining period problem and is composed of a plurality of insert body structures which are arranged and fixed to a base in a crossed mode with heads and tails mutually embedded. The insert body structures are composed of hardware head upper segment inserts, hardware head lower segment inserts, insert empty avoiding structures and hardware tail inserts. The hardware head upper segment inserts, the hardware head lower segment inserts and the hardware tail inserts are of independent structures which are not connected. The insert empty avoiding structures are arranged on the two sides of the hardware head lower segment inserts. The whole insert structure is separated into the multiple independent inserts, when damage occurs, only the damaged inserts need to be replaced, and cost is greatly reduced; the insert empty avoiding structures are added, the empty avoiding function and the positioning function are achieved at the same time, deformation of hardware can be found when the hardware is injected in a molding mode and placed, and damage of the inserts is avoided.
Description
Technical field
The present invention relates to the mould insert structure field of five metals, particularly relate to the insert structure of the rear mold of connector class five metals moulding.
Background technology
Interconnection technique is the focus of current surging development, and the fierce expansion in information terminal box communications equipment market that it and mobile phone, internet are used, the continuous expansion of Fibre Optical Communication Technology application are closely related.Communications connectors is a kind of of connector.Connector, i.e. CONNECTOR, domestic connector, the plug and socket of being also called.Generally refer to electric connector.The device that connects two active devices, transmission current and signal.Be widely used in the military systems such as space flight, aviation, national defence.Connector is blocked between place or isolated obstructed circuit at inside circuit, erects the bridge of communication, thereby makes current flowing, makes circuit realize predetermined function.Connector is indispensable parts in electronic equipment, along the path of current flowing, observes, and always finds that there is one or more connectors.Connector form and structure are Protean, along with differences such as application, frequency, power, applied environments, have various multi-form connectors.Communications connector belongs to the InterWorking Equipment of Network Transfer Media, and the connector performance adopting may affect whole communication system.At present, model and the standard of communications connector product are a lot, wherein mainly comprise the optical fiber connector and electric connector.
But, the shell fragment of the five metals of connector can be subject to mould extruding and damage at injection moulding process, the gold-plated contact-making surface of five metals can be worn, and product in use can not guarantee resistance to wear and good conductivity, and contact interface cannot guarantee high reliability and stability, simultaneously, the mold insert process-cycle, if be difficult to find when five metals has distortion to put five metals, after mold insert damage, need integral replacing mold insert, cost requirement is high, and during production, five metals shell fragment is highly unstable; Five metals shell fragment contact-making surface coating be prone to scratch, affect properties of product.
Summary of the invention
For solving the problems of the technologies described above, the invention provides the insert structure of the rear mold of connector class five metals moulding.
The technical solution adopted for the present invention to solve the technical problems is: the insert structure of the rear mold of connector class five metals moulding, by a plurality of mold insert agent structures end to end mutually embedding cross arrangement being fixed on base form; Wherein, described mold insert agent structure is comprised of five metals head epimere mold insert, five metals head hypomere mold insert, mold insert clearance structure and five metals afterbody mold insert; Described five metals head epimere mold insert, five metals head hypomere mold insert and five metals afterbody mold insert are mutual disjunct absolute construction; Described mold insert clearance structure is arranged on the both sides of five metals head hypomere mold insert.
On described five metals head epimere mold insert, five metals head hypomere mold insert and five metals afterbody mold insert, be respectively arranged with fixing hole.
Operation principle: five metals head epimere mold insert is structure as a whole; Five metals head hypomere mold insert is structure as a whole; Five metals afterbody mold insert is structure as a whole; Mold insert clearance structure protection five metals is avoided the pressure of injection moulding in forming process, and increases the positioning function of five metals; When mold insert has damage, only need to change the mold insert of damage, without whole replacings.
Beneficial effect of the present invention: the insert structure of the rear mold of connector class five metals of the present invention moulding, originally whole insert structure is split as to a plurality of independently parts, the whole process-cycle of mold insert is shortened, when mold insert is damaged, replacing mold insert is easy, and the mold insert that only need change damage, cost significantly reduces; Owing to having added mold insert clearance structure, can play two functions of empty avoiding and location simultaneously, if five metals has distortion, when placing five metals, injection moulding can find, avoid mold insert to occur damage; Meanwhile, can not have influence on the contact flat spring height of five metals and the coating of five metals contact-making surface.

Embodiment
In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples, the present invention is described in further detail, this embodiment, only for explaining the present invention, does not form and limits protection scope of the present invention.
Embodiment
As shown in Figures 1 to 4, the insert structure of the rear mold of connector class five metals moulding, by a plurality of mold insert agent structures end to end mutually embedding cross arrangement being fixed on base 5 form; Wherein, described mold insert agent structure is comprised of five metals head epimere mold insert 1, five metals head hypomere mold insert 2, mold insert clearance structure 3 and five metals afterbody mold insert 4; Described five metals head epimere mold insert 1, five metals head hypomere mold insert 2 and five metals afterbody mold insert 4 are mutual disjunct absolute construction; Described mold insert clearance structure 3 is arranged on the both sides of five metals head hypomere mold insert 2.
On described five metals head epimere mold insert 1, five metals head hypomere mold insert 2 and five metals afterbody mold insert 4, be respectively arranged with fixing hole 6.
Operation principle: five metals head epimere mold insert 1 is structure as a whole; Five metals head hypomere mold insert 2 is structure as a whole; Five metals afterbody mold insert 4 is structure as a whole; Mold insert clearance structure 3 protection five metals are avoided the pressure of injection moulding in forming process, and increase positioning function; When mold insert has damage, only need to change the mold insert of damage, without whole replacings.
The insert structure of the rear mold of the connector class five metals moulding of the present embodiment, process-cycle is 7 days (existing insert structure is 15 days), machining accuracy is that the existing insert structure of 0.005mm(is 0.01mm), (existing insert structure adopts grinding machine to adopt grinding machine processing, CNC equipment, EDM equipment), processing cost is 10000 yuan (existing insert structure is 20000 yuan), the frequency that repairs a die is 60 days/time (existing insert structure is 2 days/time), the expense of repairing a die is 60 yuan/time (existing insert structure is 350 yuan/time) at every turn, the stability of finished product five metals shell fragment height is ± the existing insert structure of 0.05mm(is ± 0.1 mm).
