Abstract
The invention discloses a separating typed mobile mould structure of hinged mechanism of casting shaping machine, front mobile mould with assembling die, bearing block and back mobile mould, wherein the bearing block is set between front and back mobile moulds with two ends resisting front and back mobile moulds; the separating typed mobile mould improves the force condition of board and mould, which reduces the deformation of mould effectively.
Description
Affiliated technical field
The present invention relates to the moving platen of injection moulding machine clamping mechanism, relate in particular to the separate type mould structure of mechanical reaming type clamping mechanism.
Background technology
At present, Chang Gui injection machine mechanical part is made up of ejecting mechanism, clamping and frame etc.In the most frequently used mechanical reaming type clamping, mainly reached the machine hinge body and formed by quiet template, moving platen, tailgate.Mould is placed between moving platen and the quiet template, in injection process, is moved to quiet template by moving platen, mates and provide the account mould power of sizing material in die cavity, and mold clamping force does not generally wait to several kilotons by tens tons.Through supercooling, moving platen moves and opens mould goods backward, by ejecting mechanism goods is ejected in die cavity then in die cavity.Whole process of production to the basic demand of clamping is: enough mold clamping force and ejecting forces are provided.
Consult Fig. 1 to Fig. 3,,, obviously have two problems because integral structure is adopted in the moving platen design though common mechanical reaming type injection machine can provide enough mold clamping force and ejecting forces:
(1) the mold clamping force F that is delivered on the mould 10 distributes inadequately evenly rationally; The power that the machine hinge is delivered on the moving platen 12 is born by the hinge ear 120 that separates up and down, moving platen 12 stressed backs produce distortion, its distortion can be delivered on the mould, cause die deformation, the final phenomenon that occurs is that finning appears in goods easily, and need mold clamping force higher, and influence the service life of mould.
(2) it is reasonable inadequately to eject the some distribution on ejector retainner plate 11.Ejector retainner plate 11 designs are in moving platen 12 inside, so ejector retainner plate is subjected to the restriction of template 12 structures in the size of left and right, up and down direction.Therefore ejector retainner plate often be difficult to reasonable setting, cause the ejector retainner plate ejecting force unreasonable, phenomenons such as ejector retainner plate fracture appear easily.
Summary of the invention
In order to overcome the deficiency of above-mentioned technology, the invention provides a kind of separate type mould structure of mechanical reaming type clamping mechanism, this separate type mould structure improves template and mould force-bearing situation, and provides to greatest extent and eject locational space.
The technical solution adopted for the present invention to solve the technical problems is: the back moving platen that is provided with preceding moving platen, rest pad and the junctor hinge body of installation mold, between moving platen and the back moving platen, its two ends offseted with preceding moving platen and back moving platen respectively before rest pad was arranged on.
Described rest pad roughly evenly distributes along moving platen center, back.
The middle part of moving platen before described rest pad is bearing in.
Moving platen, rest pad and back moving platen constitute for casting is whole or are made of the single part assembling before described.
The invention has the beneficial effects as follows; carry out the separate type design at the moving platen in the clamping; by rest pad is set; reach and improve template and mould force-bearing situation; effectively reduce because the die deformation (being delivered on the mould) that template deformation causes; and provide to greatest extent to eject locational space, improve the template serviceability.The clamping system of common mechanical reaming type injection machine can be reached the performance level of ordinary straight press on to the mold stresses transmission by the present invention.

The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
Consult Fig. 4 to Fig. 7; the separate type mould structure of mechanical reaming type clamping mechanism; it is characterized in that: the back moving platen 3 that is provided with preceding moving platen 1, rest pad 2 and the junctor hinge body of installation mold; between moving platen 1 and the back moving platen 3, its two ends offseted with preceding moving platen 1 and back moving platen 3 respectively before rest pad 2 was arranged on.Moving platen 1, rest pad 2 and back moving platen 3 constitute for casting is whole or are made of the single part assembling before described.
The rest pad 2 of present embodiment has four, and described rest pad 2 roughly evenly distributes along moving platen 3 centers, back.The middle part of moving platen 1 before described rest pad 2 roughly is bearing in.Though the power after the slave hinge is delivered to like this on the moving platen is still born by the hinge ear 30 that separates up and down, but through after the transmission of rest pad 2, the middle part of moving platen 1 before its clamp force F concentrates on, improved the stressing conditions of preceding moving platen 1, even back moving platen 3 deforms, through the obstruct of rest pad 2, its influence to preceding moving platen 1 is quite little, satisfies specification requirement.In addition, preceding moving platen 1 and back moving platen 2 separate types design, and have increased to provide to eject locational space, make the greater flexibility that is provided with of ejector retainner plate 4.
Above-described specific embodiment only is preferred embodiment of the present invention, and the equivalent arrangements of being done according to the present patent application claim all should be technology of the present invention and contains such as.
