Abstract
The invention discloses a three-plate mold with a mold opening sequence control structure. The three-plate mold comprises a fixed mold fixing plate, a runner plate, a fixed template, and a moving template from top to bottom in turn; a brake nut is arranged in a step hole of the fixed mold fixing plate; the runner plate is provided with a withdrawal hole opposite to the step hole; the lower end of the brake bolt passes through the withdrawal hole; the fixed template is provided with a via hole and a mounting hole in which a spring is arranged; a bolt pull rod passes through the via hole and the mounting hole to be connected with the brake bolt; and the fixed template and the moving template are connected through a mold locking component. The three-plate mold with the structure is used reliably and easily, difficult to damage, easy to process, convenient to install and low in installation precision requirement, can automatically compensate installation errors to avoid influence, overcomes the instability that the fixed template and the moving template are finally separated by means of product demolding force, and provides guarantee for finally separating the fixed template and the moving template.
Description
Technical field
The invention belongs to a kind of mould, relate in particular to a kind of die sinking sequential control structure of mould.
Background technology
Each the template die sinking of general three template dies is in proper order, at first is that runner plate separates earlier with solid plate, secondly is that runner plate separates with the cover half fixed head, is that solid plate and moving platen separate at last.
At present shree plates mold is to rely on product and parcel power between active and inactive mold core and the die cavity that solid plate and moving platen are separated at last, and this to make solid plate and moving platen by the required knockout press of product separately be insecure at last.
Summary of the invention
Technical problem to be solved by this invention is mechanically to control three template dies that have die sinking sequential control structure of each template die sinking order of three template dies.
Adopt following technical scheme in order to solve the problems of the technologies described above: a kind of three template dies that have die sinking sequential control structure; Comprise cover half fixed head, runner plate, solid plate and moving platen from top to bottom successively; Braking bolt is arranged in the shoulder hole of cover half fixed head, and runner plate is provided with and the corresponding resigning hole of shoulder hole, and resigning hole is passed in the braking bolt lower end; Solid plate be provided with via hole and in establish the installing hole of spring, bolt draw bar passes via hole and installing hole links to each other with braking bolt; Connect through the locked mode assembly between solid plate and the moving platen.
Described locked mode assembly comprises the locking bed of installing on the pull bar installed on the solid plate and the moving platen, and locking bed matches with pull bar.
The pull bar front end is arc surface or inclined-plane, and the anterior side of pull bar is provided with the arc surface groove or the inclined-plane indent is arranged; The locking bed both sides are provided with screwed hole and the tight screw of Built-in lock, the arc surface groove that lock-screw end and pull bar are anterior or have the inclined-plane indent to match.
Lock-screw is made up of the steel ball, spring, the holding screw that are installed in successively in the tightening swivel nut.
Structure of the present invention is used reliable, and is simply not fragile, is easy to processing, installs more convenient and installation accuracy is less demanding, can remedy alignment error automatically, do not influence use.Overcome the unstability that relies on product stripping power that solid plate and moving platen are separated at last, guarantee separately is provided at last for guaranteeing solid plate and moving platen.
Description of drawings
Fig. 1 has the structural representation of three template dies of die sinking sequential control structure for the present invention.
Fig. 2 is the structural representation of locked mode assembly of the present invention.
Fig. 3 is the structural representation of lock-screw of the present invention.
The specific embodiment
As shown in Figure 1, a kind of three template dies that have die sinking sequential control structure comprise cover half fixed head 1, runner plate 2, solid plate 3 and moving platen 4 from top to bottom successively, and braking bolt 5 is arranged in the shoulder hole of cover half fixed head 1, and stepped hole is up big and down small; Runner plate 2 is provided with and the corresponding resigning hole of shoulder hole, and resigning hole is passed in braking bolt 5 lower ends; Solid plate 3 be provided with via hole and in establish the installing hole of spring 6, the via hole that is provided with on the solid plate 3 is up-small and down-big shoulder hole, bolt draw bar 7 lower end round platform diameters are greater than the via hole upper diameter; Bolt draw bar 7 passes via hole and installing hole links to each other with braking bolt 5; Connect through the locked mode assembly between solid plate 3 and the moving platen 4.As shown in Figure 2, the locked mode assembly comprises through screw and is installed in the pull bar 8 on the solid plate and is installed in the locking bed 9 on the moving platen through screw that pull bar 8 front ends are arc surface or inclined-plane, and the anterior side of pull bar is provided with the arc surface groove or the inclined-plane indent is arranged; Locking bed 9 both sides are provided with screwed hole and the tight screw 10 of Built-in lock, the arc surface groove that lock-screw end and pull bar are anterior or have the inclined-plane indent to match.The bulb that matched moulds back stay lateral grooves is aimed on the holding screw basically gets final product, pull bar jack center on the locking bed and pull bar center basically identical just can because can regulate the lock-screw 10 of both sides steel ball and pull bar groove are adjacent to.The size of locked mode dynamics can be marked closely screw through adjusting and regulate.As shown in Figure 3, lock-screw 10 is made up of the steel ball 11, spring 12, the holding screw 13 that are installed in successively in the tightening swivel nut 14.
During matched moulds, the steel ball of lock-screw is stirred, compressed to the rod head arc surface, in the steel ball indentation lock-screw (spring is arranged in the lock-screw, and steel ball can freely stretch under the effect of external force).When matched moulds put in place, steel ball stretched out lock-screw and is stuck in the arc groove of pull bar active and inactive mold is locked.
During die sinking, solid plate and moving platen can't be opened under the effect of locked mode assembly, and runner plate at first separates with solid plate under the effect of spring.Behind the shoulder contact solid plate of bolt draw bar, the traction braking bolt promotes runner plate, makes runner plate and cover half fixed head separately.Continue die sinking, on braking bolt step surface and the cover half fixed head accordingly the stepped hole bottom surface contact the solid plate stop motion.Continue die sinking again, the steel ball on the pull bar arc groove extruding lock-screw on the solid plate, the steel ball withdrawal, solid plate and moving platen are opened.Realized that three template dies open by set die sinking in proper order.
