Abstract
The invention provides a simple type tunnel sliding block mechanism. The mechanism comprises a ternary sliding block head, a secondary sliding block head, a primary bent pin type sliding block head, an oil cylinder pull rod, an oil cylinder installation plate, a core pulling power cylinder, a sliding groove base plate and a sliding groove guiding press bar. A mechanism core pulling component comprises the ternary sliding block head and the secondary sliding block head, wherein a T-shaped groove is formed in the secondary sliding block head in a matched mode, and a bent pin type oblique hole matched with the primary bent pin type sliding block head is formed in the secondary sliding block head; the ternary sliding block head and the secondary sliding block head are installed in a mold core insert through a channel, and the ternary sliding block head is used under the condition of mechanism space insufficiency when the mold core side conducts core pulling towards the interior of the center. The tunnel sliding block mechanism is designed to meet the requirement for inner core pulling of the mold core side during product molding, the structure of a mold is simplified, and the production cost of the mold is reduced; the structural design is reasonable, the structure is compact, working is stable, and safety and reliability are realized.
Description
Technical field
The present invention relates to injection mold mechanism design field, be specially a kind of simple type tunnel slide block mechanism.
Background technology
Molded product is when die core side needs inner core pulling, when conventional core-pulling mechanism space layout is inadequate, special internal core-pulling mechanism need be adopted, and internal core-pulling mechanism more simple mould more easily process, mould is manufactured cost and is relatively reduced, and its reliability of mechanism simplifying, stability are better.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of simple type tunnel slide block mechanism, comprises three slider heads, secondary slide block head, once curved pin slider head, oil cylinder pull bar, oil cylinder installing plate, actuator cylinder of loosing core, chute base plate, chute guide layering.
As preferably, described mechanism assembly of loosing core comprises on three slider heads, secondary slide block head and offers coupling T-slot, and secondary slide block head offers the curved pin inclined hole coordinated with once curved pin slider head; Three times slider head, secondary slide block head are installed in mold cores mold insert by conduit; Three slider heads are used for applying when when mould die core side is loosed core to central interior, mechanism's installation space is inadequate.
As preferably, described mechanism Power Component comprises oil cylinder pull bar, oil cylinder installing plate, actuator cylinder of loosing core, chute base plate, chute guide layering; Curved pin slider head head is for leading curved pin, and afterbody is T-slot slide body, is installed on chute base plate by itself T-slot, chute guide layering; Actuator cylinder of loosing core is connect by oil cylinder installing plate and chute base plate; Actuator cylinder of loosing core is connect by oil cylinder pull bar and curved pin slider head afterbody slide body, drives the action of curved pin slider head.
Beneficial effect: a kind of simple type tunnel slide block mechanism that the present invention adopts technique scheme to provide, for the requirement of core side inner core pulling during formed product and design ap-plication, simplifies mould structure, reduces mould and manufacture cost; Reasonable in design, compact conformation, working stability, safe and reliable.

Detailed description of the invention
Fig. 1-3 is depicted as related description figure of the present invention; A kind of simple type tunnel slide block mechanism, comprises three slider heads 1, secondary slide block head 2, once curved pin slider head 3, oil cylinder pull bar 4, oil cylinder installing plate 5, actuator cylinder 6 of loosing core, chute base plate 7, chute guide layering 8.
Described mechanism assembly of loosing core comprises on three slider heads 1, secondary slide block head 2 and offers coupling T-slot, and secondary slide block head 2 offers the curved pin inclined hole coordinated with once curved pin slider head 3; Three times slider head 1, secondary slide block head 2 are installed in mold cores mold insert by conduit; Apply when when three times slider head 1 is loosed core to central interior for mould die core side, mechanism's installation space is inadequate.
Described mechanism Power Component comprises oil cylinder pull bar 4, oil cylinder installing plate 5, actuator cylinder 6 of loosing core, chute base plate 7, chute guide layering 8; Curved pin slider head 3 head is for leading curved pin, and afterbody is T-slot slide body, is installed on chute base plate 7 by itself T-slot, chute guide layering 8; Actuator cylinder 6 of loosing core is connect by oil cylinder installing plate 5 and chute base plate 7; Actuator cylinder 6 of loosing core is connect by oil cylinder pull bar 4 and curved pin slider head 3 afterbody slide body, drives the action of curved pin slider head 3.
During real work, as shown in Figure 3, its motion operation principle is as follows:
1) after die sinking, after mould somatotype is opened, to loose core actuator cylinder 6 action, pull once curved pin slider head 3 to move by direction shown in power F1 by oil cylinder pull bar 4, F1 power by curved pin in figure 3 a point produce downward to the tensile force f 3 of secondary slide block head 2 effect and the frictional component F2 along curved pin skewed slot direction; Tensile force f 3 to produce sub-power and the F5 frictional force along T-slot glide direction shown in the F4 of loosing core left to three slider heads 1 at b point place; Along with secondary slide block head 2 moves down, three times slider head 1 progressively completes loosing core inside die core;
2) when resetting, process is contrary with action of loosing core, after mould cavity is closed, to loose core actuator cylinder 6 action, promote once curved pin slider head 3 by the oppositely movement of direction shown in power F1 by oil cylinder pull bar 4, inverted-F 1 power by curved pin in figure 3 a point produce the reversal interlocking relay F3 to secondary slide block head 2 effect upwards and reverse friction component F2 along curved pin skewed slot direction; Reversal interlocking relay F3 to produce shown in the F4 of loosing core oppositely sub-power and inverted-F 5 frictional force along T-slot glide direction to the right to three slider heads 1 at b point place; Move along with on secondary slide block head 2, three slider heads 1 progressively complete the complete reset inside die core, and mould closes, and waits for the beginning of next injection cycle.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit, those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
