Abstract
The utility model discloses a kind of injection mold and force return mechanism, comprise cover half, dynamic model, inserted link, rotating shaft, fork, liftout plate, baffle plate; Described cover half is relative with dynamic model and establish, and the upper end of inserted link is fixed on cover half, and dynamic model is inserted in the lower end of inserted link; One end of described fork is hinged on dynamic model by rotating shaft, and the other end of fork is free end, and the motion track that this free end reaches inserted link can lean with the lower end of inserted link, can around shaft swing at the ejection draft link free end of inserted link; Described baffle plate is fixedly mounted on the side of liftout plate and is positioned on the swinging track of fork free end, and fork free end can the baffle plate of ejection downwards.Because the utility model is primarily of compositions such as inserted link, rotating shaft, forks, structure very simple, cost is lower; The utility model drives fork by the pressure of inserted link, and fork is forced to drive liftout plate to move down fast by baffle plate, and having stable behavior is reliable, ensure that slide block and thimble can not interfere.
Description
Technical field
The utility model relates to a kind of mould of plastics, particularly relates to a kind of injection mold and forces return mechanism.
Background technology
Plastic injection mould is the instrument producing plastic products, and application widely.In plastic products injection moulding, have bottom all sliding block of male dies on the mould of thimble, in order to during anti-limited slip block action and thimble collide; need first thimble to be resetted; to avoid both to collide, for this reason, need to design a kind of device ensureing the leading return of thimble.
Summary of the invention
The purpose of this utility model is to provide that a kind of structure is simple, with low cost, the reliable injection mold of having stable behavior forces return mechanism.
For achieving the above object, technical solution of the present utility model is:
The utility model is that a kind of injection mold forces return mechanism, comprises cover half, dynamic model, inserted link, rotating shaft, fork, liftout plate, baffle plate; Described cover half is relative with dynamic model and establish, and the upper end of inserted link is fixed on cover half, and dynamic model is inserted in the lower end of inserted link; One end of described fork is hinged on dynamic model by rotating shaft, and the other end of fork is free end, and the motion track that this free end reaches inserted link can lean with the lower end of inserted link, can around shaft swing at the ejection draft link free end of inserted link; Described baffle plate is fixedly mounted on the side of liftout plate and is positioned on the swinging track of fork free end, and fork free end can the baffle plate of ejection downwards.
The utility model also comprises travel switch and push pedal; Outside liftout plate, install a push pedal, travel switch is arranged on the side of liftout plate and the contact of travel switch is positioned on the motion track of push pedal, and push pedal can lean with the contact of travel switch.
Adopt after such scheme, because the utility model is primarily of inserted link, rotating shaft, fork, composition, structure very simple, cost is lower; The utility model drives fork by the pressure of inserted link, and fork is forced to drive liftout plate to move down fast by baffle plate, and having stable behavior is reliable, ensure that slide block and thimble can not interfere.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model
Fig. 2 is side view of the present utility model.
Detailed description of the invention
As shown in Figure 1 and Figure 2, the utility model is that a kind of injection mold forces return mechanism, comprises cover half 1, dynamic model 2, inserted link 3, rotating shaft 4, fork 5, liftout plate 6, baffle plate 7, travel switch 8 and push pedal 9.
Described cover half 1 is relative with dynamic model 2 and establish, and the upper end of inserted link 3 is fixed on cover half 1, and dynamic model 2 is inserted in the lower end of inserted link 3.
One end of described fork 5 is hinged on dynamic model 2 by rotating shaft 4, the other end of fork 5 is free end 51, the motion track that this free end 51 reaches inserted link 3 can lean with the lower end of inserted link 3, can swing around rotating shaft 4 at ejection draft link 5 free end 51 of inserted link 3.
Described baffle plate 7 is fixedly mounted on the side of liftout plate 6 and is positioned on the swinging track of fork 5 free end 51, and fork 5 free end 51 can the baffle plate of ejection downwards 7, and then drives and liftout plate 6 that baffle plate 7 is fixed together moves down fast.
Outside liftout plate 6, install a push pedal 9, travel switch 8 to be installed on square iron 10 and is positioned at the side of liftout plate 6, and the contact of travel switch 8 is positioned on the motion track of push pedal 9, and push pedal 9 can lean with the contact of travel switch 8.
It should be noted that: in the present embodiment, be provided with two forks 5, these two forks 5 are established relatively, and inserted link 3 can penetrate two fork 5 opposite positions, drive two forks 5 to swing to lower swing around rotating shaft 4 simultaneously, drive the liftout plate 6 be fixed together with baffle plate 7 to move down fast.
Operation principle of the present utility model:
1, eject state: the position of sign A is as shown in Figure 2 the state ejected residing for rear fork 5, realize the guide wheel of this process mainly after die sinking under the rod effect of board top and inside fork 5 centered by rotating shaft 4 in the baffle plate be fixed on liftout plate 67 mechanical movements.
2, return: power during return is fixed on inserted link 3 on cover half 1 with the motion of cover half 1 matched moulds movement locus, when fork 5 after inserted link 3 head and fork 5 head contact stressed with rotating shaft 4 for moving thus the baffle plate 7 be pressed onto on liftout plate 6 makes liftout plate 6 draw back to designing the position needing to stop in the center of circle.
Specification:
Inserted link 3 length must be exceeded the state after fork 5(return) more than 50mm (neither be certain, need in a word to calculate when liftout plate 6 return front-slider to move to thimble position), touch fork 5 in advance and make liftout plate 6 leading return during inserted link 3 return longer due to length in principle; Have on electronic surveillance basis at board and also can carry out more effective supervision thus enhance productivity by position placement travel switch 8 controller after liftout plate 6 return.
The above, be only the utility model preferred embodiment, the quantity of fork can be determined according to needs, therefore the scope of the utility model enforcement can not be limited with this, namely the equivalence change done according to the utility model claim and description with modify, all should still belong in scope that the utility model patent contains.
