The described mechanism that is used to open two and half Sa of, the Sb of mould has guaranteed two and half Sa of of mould, quick and symmetrical the opening of Sb.

Each epipleural P1a, P2a, be orthogonal to mould two and half Sa of, Sb open the direction translation, the first half Sa of mould is constrained in it or from its release with respect to upside hydraulic cylinder U1a, the U2a of correspondence.

The device C that is used to lock two and half Sa of, the Sb of mould is arranged in the rear (Fig. 3) of two and half Sa of, the Sb of mould substantially.

Each locking device C is made of two element C1, C2 being juxtaposed to each other, and wherein each element has C shape cross section, and described element is connected with each other by the parts that traverse that are fit to.

Described element C1, C2 side by side is arranged to, and the wing Cf of each in them is in the face of another element C2, C1, and midfeather Cg be parallel to mould two and half Sa of, Sb open direction (Fig. 4 b).

Two element C1, the C2 of locking device C and registration, thereby the distance between the midfeather Cg of the C shape cross section of described closing element C1, C2 is less times greater than two and half Sa of of mould, the width of Sb, and the wing Cf of their C shape cross section be orthogonal to mould two and half Sa of, Sb open direction.

The apparent surface Cf1 of the wing Cf of each element C1, the C2 of locking device C shrinks towards the direction that locking device C advances.In this case, described locking device C, that is to say two side by side element C1, the C2 insertion on two and half Sa of, the Sb of mould promoted and the pressure minimum on half Sa of, the Sb that need close two of mould.

Among two element C1, the C2 of locking device C each laterally, that is to say and on the side of the midfeather Cg opposite, be provided with wheel Cr or other element that they slide on suitable guide rail R with wing Cf.

One or more hydraulic cylinder N along with the direction of opening the direction quadrature described locking device C of translation on described guide rail R of two and half Sa of, the Sb of mould.

Locking device C is connected to circle or the O2 of annular planar portion, and by at least two radially translations of hydraulic cylinder N, one of them hydraulic cylinder is positioned at the position of the mechanism that opens mold halves Sa, Sb, and a hydraulic cylinder is in the position of the mechanism of closing molding half Sa of, Sb.

Each the locking device C that seals a pair of mold halves Sa, Sb is restrained to circle or the O2 of annular planar portion, thereby the rotation of described circle or the O2 of annular planar portion is moved every couple of mold halves Sa, Sb and relevant locking device C successively near the peripheral erection part F3 of fixing framework F and in the position of hydraulic cylinder U1a, U1b, U2a, U2b.

In the process of molded article, mold halves Sa, Sb link together, and element C1, the C2 translation on mold halves Sa, Sb of locking device C, thereby they are kept closing.

In this position, the bar Bs of mould first half Sa almost completely is positioned at the below of circle or the O2 of annular planar portion, and their slide block B p is suspended at described par O2 below.

Because thereby two and half Sa of, the Sb of the rotation locking device C of circle or the O2 of annular planar portion and mould when reaching first couple of hydraulic cylinder U1a, U1b, begin to open the process of mold halves Sa, Sb, and this process comprises following key step.

Upside hydraulic cylinder U1a is contracted, and that is to say, from two and half Sa of of mould, Sb is released and isolate.

In order to open two and half Sa of, the Sb of mould, upside hydraulic cylinder U1a is stretched, thereby makes the Connection Element Ag of epipleural P1a near the first half Sa of mould.

Epipleural P1a passes through corresponding hydraulic cylinder M1a by translation, thereby it is constrained in the Connection Element Ag of the first half Sa of mould.

Two hydraulic cylinder U1a, U1b further stretch, thereby exert pressure on two and half Sa of, the Sb of mould, and they are kept being clamped together.

Locking device C passes through corresponding hydraulic cylinder N by translation, thereby its two and half Sa of, Sb from mould is moved away, and discharges two and half ones, and they are by being held clamping by hydraulic cylinder U1a, U1b institute applied pressure.

At last, upside hydraulic cylinder U1a is by fast retractile, and downside hydraulic cylinder U1b stops to exert pressure, thereby separates and open two and half Sa of, the Sb of mould.This upside hydraulic cylinder U1a that moves through that opens two and half Sa of, the Sb of mould is implemented, and the speed of wherein said upside hydraulic cylinder is enough to open at once two and half Sa of, the Sb of mould.

The described material that prevents molding of opening fast of the two and half S a of, the Sb of mould expands in the space that two and half Sa, Sb by mould are limited.

The raising of the first half Sa of mould makes slides in the counter-guide of bar Bs on being arranged on circle or the O2 of annular planar portion of first half Sa of mould.In this position, downside slide block B p is elevated in the position of the guide rail of pedestal F 1 or guiding piece F5 or is higher than it.

The article that the operator makes from mould Sa, the Sb demoulding, and if necessary, two and half Sa of, the Sb of cleaning mold, thus their preparations are used for mold cycle subsequently.

Circle or the O2 of annular planar portion can realize the part rotation of the progressively erect-position between the cleaning of two and half Sa of, the Sb of the demoulding of the article of making and mould.

Described circle or the O2 of annular planar portion are further rotated two and half Sa of of mould, the position that Sb moves to second couple of hydraulic cylinder U2a, U2b, and two and half Sa of, the Sb of closing molding is provided.

In the process of these rotations, moving of first half Sa is not constrained in upside hydraulic cylinder U1a, U2a.

Downside slide block B p sits idly and slides on the guide rail of pedestal F1 or guiding piece F5, keeps bar Bs to raise, and the first half Sa of mould.

As shown in the figure when the rotation of closing hydraulic cylinder U2a, U2b finishes, the Connection Element Ag of the first half Sa of mould is engaged among the groove Ps of the epipleural P2a that closes hydraulic cylinder U2a at two and half Sa of, the Sb of mould.

In this position, the downside slide block B p of the bar Bs of the first half Sa of mould is positioned at outside the guide rail or guiding piece F5 of pedestal F1, and thereby suspends from the bar Bs of the first half Sa of mould.

Same process must be done with opposite order, with two and half Sa of, the Sb of closing molding.

Upside hydraulic cylinder U2a stretches, and downside hydraulic cylinder U2b operates in the mode of offsetting thrust, thereby connects two and half Sa of, the Sb of mould with enough pressure, so that their maintenances are clamped together.

Locking device C is urged by the hydraulic cylinder N of correspondence, thereby moves two C shape element C1, C2 abreast, and makes two and half Sa of, the Sb of their closed moulds, because the edge that tilts applies the pressure of necessity.

Subsequently, epipleural P2a translation discharges Connection Element Ag, and upside hydraulic cylinder U2a withdrawal, and the downside hydraulic cylinder stops to exert pressure makes two and half Sa of, the Sb wing Cf by element C1, the C2 of locking device C of mould be closed.

The rotation of circle or the O2 of annular planar portion makes all right mold halves Sa, Sb rotate together with relevant locking device C.Therefore, between two rotating in a circumferential direction in succession, a pair of mold halves Sa, Sb are opened by first couple of hydraulic cylinder U1a, U1b, another that open is cleaned by the operator to hydraulic cylinder Sa, Sb, and additional a pair of mold halves Sa, Sb are closed by second couple of hydraulic cylinder U2a, the U2b that is used for manufacture process subsequently.According to the present invention, especially in the situation of the goods of making two kinds of colors or different densities, material be introduced into from the top and by the step of molding in the following manner by in advance, utilize subsequently closing molding and locate one or more inserts.

Closing each step that realizes between the reopening subsequently of a pair of mold halves Sa, Sb and they is various manufacturing step, just: the keeping of heating, expansion and the shaping of two and half Sa of, the Sb of the injection of plastics, mould, correct temperature, for two and half Sa of, the Sb of mould opening and reduce temperature subsequently.

Plastic injection device I preferred orientation becomes as long as two and half Sa of, the Sb of mould are closed, and as shown in Figure 2, then just described plastics is introduced in them.

Preferably, use mold halves Sa, the Sb that is suitable for making Individual Items.In this case, the size of new rotational supporting structure that is used to have the die apparatus of single mould opening mechanism can be restricted, thereby allows it to be stored in conventional cask, and need not structure is divided into a plurality of parts.

The mould S that is used for the new rotational supporting structure of mould S equipment and has a relevant locking device C provides significant advantage, and wherein said rotational supporting structure has and is used for the single mechanism that opens the single mechanism of mould S fast and be used for closing molding S.

Opening with being connected by hydraulic cylinder Ua, Ub of two and half Sa of, the Sb of mould directly controlled, and do not have linkage, space or gap.Therefore, two and half Sa of, the Sb of mould open be fast, symmetry and linear.

Two element C1, the C2 of each locking device C make and can keep two and half Sa of, the Sb of mould to close in the process that EVA expands, thereby needn't be exerted pressure by hydraulic cylinder U1a, U1b, U2a, U2b.

The new structure that is used for mould S equipment can be contained in the less space, is contained in substantially in the cask, need not to dismantle total, or need not circle or the O2 of annular planar portion are divided into a plurality of parts in any situation.

Bar Bs and be fixed to the downside slide block B p of first half Sa of mould and the use of the guide rail of pedestal F1 or guiding piece F5 allows the first half Sa of mould to be independent of hydraulic cylinder U1a, U2a to be held and to lift.

Be used for the single opening mechanism of two and half Sa of, Sb of mould and the use of single closing structure; except the size that has limited new construction, also reduced owing to opening and closing hydraulic cylinder U1a, U1b, U2a, the fault of U2b or the shutdown that destruction causes.

19., it is characterized in that closing of two and half ones of described mould (Sa, Sb) may further comprise the steps according to the arbitrary described supporting structure that is used for die apparatus (S) of aforementioned claim:

Rotate described circle or annular planar portion (O2), and locate described mold halves (Sa, Sb) thus be closed in the described a pair of position of closing hydraulic cylinder (U2a, U2b);

Stretch described upside hydraulic cylinder (U2a), be clamped together until two and half ones (Sa, Sb) of described mould;

In two and half ones (Sa, Sb) of described mould, apply the additional pressure of described hydraulic cylinder (U2a, U2b), thus keep they each other against;

The described locking device of translation (C), until two and half ones (Sa, Sb) that the facing surfaces (Cf1) of the wing (Cf) of each element (C1, C2) of described locking device (C) is fully being pressed described mould, thereby the inboard inclined surface (Cf1) of the wing (Cf) of the C shape element (C1, C2) by described locking device (C) keeps their to close;

Discharge described upside hydraulic cylinder (U2a) from the first half (Sa) of described mould, the described upside hydraulic cylinder of withdrawing, and interrupt by described downside hydraulic cylinder (U2b) applied pressure, thereby make two and half ones (Sa, Sb) of described mould only be closed by described locking device (C).
