Description
Technical field
The present invention relates to the inner side core-pulling of die cast metal mould and plastic injection moulding mould, it is spring secondary core pulling
Mold mechanism.
Background technology
After moulding by casting, if the side wall of product has annular groove or annular boss, need to carry out by slide block in die sinking
Side core pulling, when the side wall of product has multiple annular grooves or boss, if adopt a side core-pulling, the groove of product and
Boss is easily pulled out of shape, or even directly connects disconnected, rupture, the qualification rate of impact product.Prior art is by moulded products side
The part of boss and groove is arranged to activity, after moulding by casting, outside product launch mode together with movable members, then by people
Work Separation Product and movable members, after product is separated with movable members, then are carried out by the artificial loading mould by movable members
The moulding by casting in next cycle.Though can obtain complete product using above-mentioned mold mechanism, labor strength is big, workman
When installation activity part is in mould, safety it cannot be guaranteed that, the part of moulded products side wall boss or groove is movable simultaneously,
Thus result in product size unstable.In order to overcome the deficiencies in the prior art, special provide as follows a kind of mold mechanism to solve on
State problem.
Content of the invention
The present invention is to provide the mold mechanism of spring secondary core pulling, as illustrated, carrying two on the lateral surface of product (205)
Individual groove and two boss, the small boss (e) in product (205), due to being in the groove be molded over slide block (115), molds
When, if adopting a core pulling action, the small boss (e) in product (205) just easily breaks in the groove of slide block (115).
In order to obtain perfect product, then carry out core pulling in the following way, it is achieved in that after moulding by casting, mould
Dynamic model part is moved rearwards by, and now, is arranged on the baroclinic block (165) of cover half one side and slide block (115) and separates, dynamic in being mounted in
First spring (185) of mould one side promotes slide block (115) to make translation motion to mould right, in This move, slide block (115)
Front end inclined-plane (s) and product separate, meanwhile, the rear end (m) of core (125) is vertical along baroclinic block (165) in die sinking
Sliding action is made in face (t), therefore, when sliding on the right of the first spring (185) promotion slide block (115) is to mould, core (125)
Front end withstand product (205), then the small boss (e) of product (205) is successfully de- from the groove of slide block (115)
Go out.Dynamic model part is moved after continuing, and at this moment, the rear end (m) of core (125) runs to the end of the vertical plane (t) of baroclinic block (165)
Point, dynamic model part is moved after continuing, and at this moment the rear end (m) of core (125) disengages the vertical plane (t) of baroclinic block (165), then core
(125) the inclined-plane p of rear end (m) and baroclinic block (165) collides.Dynamic model part is moved after continuing, the at this moment rear end of core (125)
M () is slided along the inclined-plane (p) of baroclinic block (165), in This move, second spring (135) promotes core (125) right to mould
Square action, then the front end of core (125) extract out from the groove (h) of product (205).When slide block (115) and core (125)
After extracting out from product completely, at this moment push rod (195) promotes product (205) to deviate from outside mould from moving platen (175).Spring secondary
The mold mechanism of core pulling, its advantage is: it utilizes spring secondary core pulling, and action is solid and reliable, and mould structure is simple, system
Make, install, debugging conveniently, its high degree of automation simultaneously, quality of item is graceful.It is suitable for metal die-casting mold and plastic injection
The core pulling of mould similar articles.The mold mechanism of spring secondary core pulling, solves a core-pulling die mechanism, the groove of product or
Boss is easily pulled, or even directly breaks, ruptures, the problem of the qualification rate of impact product.Solve mould right-hand side work Separation Product and
The mold mechanism of movable members, labor strength is big, and safety of workers cannot ensure, the problem of product size stability difference.
The mold mechanism of spring secondary core pulling, is characterized in that: it includes fixed half and moving half, and its cover half is by solid plate (225), cover half type

Specific embodiment:
It is illustrated as the mold mechanism of spring secondary core pulling, below to the construction of this mold mechanism, annexation and dynamic
It is described in detail as principle.
First, the operating principle of this mould is: when mould installion is in injector, fixed through moulding by casting, pressurize feeding, cooling
After type, injector driven mold dynamic model partly moves afterwards, now, is arranged on baroclinic block (165) and the slide block (115) point of cover half one side
Open, promote slide block (115) to make translation motion to mould right in the first spring (185) being mounted in dynamic model one side, at this
In action, front end inclined-plane (s) and the product of slide block (115) separate, and meanwhile, the rear end (m) of core (125) is along tiltedly in die sinking
The vertical plane (t) of briquetting (165) makees sliding action, therefore, on the right of the first spring (185) promotion slide block (115) is to mould
During slip, product (205) is withstood in the front end of core (125), and then the small boss (e) of product (205) is successfully from slide block
(115) deviate from groove.Dynamic model part is moved after continuing, and at this moment, the rear end (m) of core (125) runs to baroclinic block (165)
The terminal of vertical plane (t).Dynamic model part is moved after continuing, and at this moment the rear end (m) of core (125) disengages the vertical of baroclinic block (165)
Face (t), then collide in the rear end (m) of core (125) and the inclined-plane (p) of baroclinic block (165).Dynamic model part is moved after continuing, at this moment
Slide along the inclined-plane (p) of baroclinic block (165) in the rear end (m) of core (125), in This move, because core (125) loses tiltedly
The pressure of the vertical plane (t) of briquetting (165), then second spring (135) promotion core (125) is to the action of mould right, core
(125) front end is extracted out from the groove (h) of product (205).When slide block (115) and core (125) are extracted out completely from product
Afterwards, at this moment push rod (195) promotes product (205) to deviate from outside mould from moving platen (175).After product abjection mould is outer, mould is multiple
During position, contrary action when molding with mould dynamic model part of injector is drawn close to cover half, is the inclined-plane of baroclinic block (165) first
P collide in the rear end (m) of () and core (125) so as to core (125) moves to mould left direction, and dynamic model continues to draw close to cover half,
At this moment the inclined-plane (p) of baroclinic block (165) and wearing plate (145) are collided, and then force slide block (115) to move to mould left, make
Front end inclined-plane (s) of its slide block (115) is inserted in the groove (a) of product (205), continues matched moulds, the rear end (m) of core (125)
Place slides into vertical plane (t) place of baroclinic block (165) along the inclined-plane (p) of baroclinic block (165), and then the front end of core (125) exists
In the groove (h) of insertion product (205) in the presence of the vertical plane (t) of baroclinic block (165), continue matched moulds, baroclinic block (165)
After the inclined-plane (p) of vertical plane (t) and baroclinic block (165) compresses core (125) and slide block (115) respectively, injector ability is to mould
Carry out the moulding by casting in next cycle.
