Description

A kind of core-pulling die mechanism
Technical field
The present invention relates to metal die-casting mold and plastic injection moulding mould, is a kind of core-pulling die mechanism.
Background technology
At present, at Making mold circle, inner side core-drawing mechanism has the following two kinds version: (1) angled-lift splits inner side core-pulling mold mechanism, it is after die sinking, angled-lift splits is driven to loose core along guide runner transverse movement by the Angle Pin be arranged in mould, after loosing core and terminating, the ejecting mechanism of mould is by outside goods launch mode.(2) oblique top inner side core-drawing mechanism, it is mounted in the inclined guide of die inside, does angled core-pulling action, complete the extraction at the shaping position, inside of goods when die sinking along the gathering sill pre-seted, after loosing core and terminating, by oblique top with release outside goods launch mode together with part.Above two kinds of mold mechanisms, though loose core, action is solid and reliable, and pressure transmission is good, but for the little goods in inner space, it has been difficult to the action of loosing core of inner side, complete inner side core-pulling according to above-mentioned two kinds of structures, because goods inside is less, therefore must increase the volume of part of respectively loosing core when Making mold, owing to loosing core, part increases, therefore mould bases also increase simultaneously, so just increased substantially die manufacturing cost, simultaneously mould install, debug, keep in repair extremely inconvenient.In order to overcome the problems referred to above, spy provides following a kind of inner side core-drawing mechanism to solve problem.
Summary of the invention
The present invention is to provide a kind of core-pulling die mechanism, as shown in the figure, because there is interrupted screw-thread goods inside, the inner space of goods is less simultaneously, as adopted traditional core-pulling mechanism and ejecting mechanism to complete screw thread core pulling inside goods and pushing out product, mould volume must increase, simultaneously the difficult quality guarantee of goods, therefore in conjunction with the design feature of goods, so adopt a kind of core-pulling die mechanism to loose core.The invention has the beneficial effects as follows: the shortcoming overcoming prior art, adopt the gentle pressure of variable core to release, make the smooth demoulding of goods, realize automated production, and ensure that goods are indeformable, Functionality, quality and appealing design, mould volume reduces nearly 50% simultaneously, saves a large amount of die steels.A kind of core-pulling die mechanism, solves slide block inner side core-pulling and oblique top inner side core-drawing mechanism mould volume is large, the problem that die cost is high, solves mould and installs, debugs, keeps in repair inconvenient problem.A kind of core-pulling die mechanism of the present invention, it is characterized in that: comprise cavity plate (11) and core plate (16), outside core (24) is installed in core plate (16), the first moving platen (13) and the second moving platen (14) is provided with outside outside core (24), the top of described first moving platen (13) is provided with push piece plate (4), the both sides of push piece plate (4) are provided with " 7 " font mold insert (2), described " 7 " font mold insert (2) are fastenedly connected with nut (1) with the piston (12) of pneumatic cylinder (15), pneumatic cylinder (15) and core plate (16) are close to, the below of core plate (16) is provided with core plate (17), the below of core plate (17) is provided with fixed head (19) and Bottom clamp plate (18), described fixed head (19) is provided with interior core (21), described interior core (21) is through core plate (17) and outside core (24), when die sinking, interior core (21) separates (as shown in Figure 2) with outside core (24) with the promotion of injector push rod (23), described cavity plate (11), goods (6) are had between push piece plate (4) and outside core (24), there is intermittent screw thread the inside of goods (6).Described outside core (24) is arranged in the stepped hole of core plate (16), and the core plate (17) set by below of outside core (24) is fastenedly connected by soket head cap screw (25) and core plate (16).One of the present invention takes out mold mechanism, during the demoulding, first be that mould is opened, push piece plate (4), outside core (24), interior core (21) separates with cavity plate (11), goods stay push piece plate (4), on outside core (24) and interior core (21), continue die sinking, injector push rod (23) promotes core plate (17) and drives outside core (24) forward motion be arranged in core plate (16), in This move process, because interior core (21) is mounted on fixed head (19), therefore interior core (21) is actionless, so outside core (24) is separated with interior core (21), action is separated due to outside core (24) and interior core (21), so outside core (24) inwardly shrinks (as shown in Figure 2), in the action of this contraction, outside core (24) is separated with the intermittent screw thread of goods (6).

Detailed description of the invention:
A kind of core-pulling die mechanism as shown in the figure, it comprises cavity plate (11) and core plate (16), outside core (24) is installed in core plate (16), the first moving platen (13) and the second moving platen (14) is provided with outside outside core (24), push piece plate (4) is provided with in the top of the first moving platen (13), the both sides of push piece plate (4) are provided with " 7 " font mold insert (2), described " 7 " font mold insert (2) are fastenedly connected with nut (1) with the piston (12) of pneumatic cylinder (15), pneumatic cylinder (15) and core plate (16) are close to, the below of core plate (16) is provided with core plate (17), the below of core plate (17) is provided with fixed head (19) and Bottom clamp plate (18), interior core (21) is installed in described fixed head (19), described interior core (21) is through core plate (17) and outside core (24), when die sinking, interior core (21) separates (as shown in Figure 2) with outside core (24) with the promotion of injector push rod (23), described cavity plate (11), goods (6) are had between push piece plate (4) and outside core (24), there is intermittent screw thread the inside of goods (6).A kind of core-pulling die mechanism of the present invention, during the demoulding, first be that mould is opened, push piece plate (4), outside core (24), interior core (21) separates with cavity plate (11), goods stay push piece plate (4), on outside core (24) and interior core (21), continue die sinking, injector push rod (23) promotes core plate (17) and drives outside core (24) forward motion be arranged in core plate (16), in This move process, because interior core (21) is mounted on fixed head (19), simultaneously, core (21) is actionless, so outside core (24) is separated with interior core (21), action is separated due to outside core (24) and interior core (21), so outside core (24) inwardly shrinks (as shown in Figure 2), in the action of this contraction, outside core (24) is separated with the intermittent screw thread of goods (6), promoting piston (12) by pneumatic cylinder (15) drives push piece plate (4) outside goods (6) launch mode.During matched moulds, first be that cavity plate (11) contacts with push piece plate (4), the propulsive thrust of cavity plate (11) forces push piece plate (4) to reset, when push piece plate (4) moves to the end contact with push rod (20), opposite action when push piece plate (4) forces push rod (20) to do die sinking, promoting core plate (17) drives the outside core (24) being arranged on core plate (16) to reset, when resetting to a timing, the inner surface of outside core (24) and the exterior surface of interior core (21), at this moment the front end of outside core (24) is inserted in the front end of interior core (21), make its outside core (24) spreading (as shown in Fig. 4 and Fig. 1), continue matched moulds, after respectively opening profile and resetting completely, mould just carries out next cycle moulding by casting.
