Specific embodiment
As shown in Figure 1, Figure 2, shown in Fig. 3 A, Fig. 3 B, the utility model is a kind of high efficiency oil cyliner slide block self-locking mould, including cover half Plate 1, moving platen 2, fixed mold core 3, mavable module core 4, oil cylinder 5, head rod 6, take-up housing 7,8, two pilot pins of the second connecting rod 9th, inductive switch 10 and switch frame 20.
Described fixed mold core 3 is fixed in solid plate 1, and mavable module core 4 is fixed in moving platen 2, fixed mold core 3 and mavable module core 4 It is abutted against together, between fixed mold core 3 and mavable module core 4 die cavity is formed.
The cylinder body of described oil cylinder 5 is fixedly mounted on the side wall of solid plate 1, and take-up housing 7 is fixed in solid plate 1, sliding The middle part of block 7 offers slide block slot 71, opens up by locating slot 72 on two madial walls of slide block slot 71.
The connecting rod 8 of head rod 6 and second is provided with described slide block slot 71, is connected in head rod 6 and second Two pilot pins 9 are provided between bar 8.Described the second connecting rod 8 is slided and is nested with the slide block slot 71 of take-up housing 7, and first connects One end of extension bar 6 is connected with the piston rod rod end of oil cylinder 5, and the both sides of the other end of head rod 6 have respectively front end inclined-plane 61 and stretch in the middle part chute 81 of the second connecting rod 8, one is opened up respectively with the second connecting rod in the both sides of the second connecting rod 8 The embedding piece groove 82 that 8 middle part chutes 81 run through, respectively activity is nested with the embedding piece groove 82 of the second connecting rod 8 for two pilot pins 9, fixed The position penetrating end of bolt 9 is with the front end inclined-plane 61 of head rod 6 against the locating slot 72 of take-up housing 7 is stretched in the outer end of pilot pin 9 Interior, the inner of the second connecting rod 8 is connected with the fuse 83 for core pulling.Pilot pin 9 is under the dynamic action of oil cylinder 5 in the row of setting The motion of journey the inside, reaches the position-limiting action of the second connecting rod 8 when pilot pin 9 is into locating slot 71.
The inductive switch 10 that described oil cylinder is carried is fixedly mounted on the cylinder body of oil cylinder 5 by switch frame 20, with injection Machine connects, and opens 10 passes and gives injection molding machine action signal by sensing, realizes being connected for mold actions and injection molding machine action.
Operation principle of the present utility model:
During matched moulds, oil cylinder 5 promotes the second connecting rod 8 to move forward with head rod 6, until before the second connecting rod 8 To the side stop motion of fixed mold core 3, now the pilot pin 9 in the second connecting rod 8 is flat with the locating slot 72 on take-up housing 7 on end top Together, due to there is intersegmental gap A between the front end of head rod 6 and the second connecting rod 8(As shown in Figure 4), when the second connecting rod 8 is stopped In the case of only moving, head rod 6 can continue to move forward a segment distance, in this moving process, the second connection The pilot pin 9 of the inside of bar 8 side shifting outward in the presence of the front end inclined-plane 61 of head rod 6, when the leading portion top of head rod 6 Firmly during the second connecting rod 8, the afterbody of pilot pin 9 touch the straight flange 62 of head rod 6(As shown in Figure 4), the head front end of pilot pin 9 Inclined-plane 61 is just locked in the inside of locating slot 72 on take-up housing 7, prevents the second connecting rod 8 from retreating, so as to reach mechanical system lock The firmly function of the second connecting rod 8.
Die sinking process:Oil cylinder 5 is moved backward with head rod 6, until the connecting rod 8 of head rod 6 and second it Between gap B(As shown in Figure 5, Figure 6)Cover, head rod 6 could drive and moved after the second connecting rod 8, now the second connection The pilot pin 9 of the inside two sides of bar 8 is due to by the second connecting rod 8 pulling force backward, the locating slot 72 on take-up housing 7 of pilot pin 9 Guiding under start to medial movement, until the completely out locating slot 72 of pilot pin 9, head rod 6 could not have any resistance Power moves the second connecting rod 8 to bottom.
Part manufacture of the present utility model:
First, an all-in-one-piece take-up housing 7 is made, two locating slots 72 is processed on take-up housing 7 and is used for locking the second company Extension bar 8, the bottom of take-up housing 7 increases a positioning boss, for the second connecting rod 8 is accurately fixed on solid plate 1, slide block Seat 7 is fixed with four screws on solid plate 1 from front, and a screw increased the second connecting rod 8 of embedding piece groove 82 in both sides, Pilot pin 9 can smoothly be moved in the inside of embedding piece groove 82 of the second connecting rod 8, and two screws are used for the pilot pin of locking sliding block 9, a screw is used for pulling the head rod 6 of the second connecting rod 8, head rod 6 to process a screw hole above, be used for Remaining is set to be connected with the piston rod of oil cylinder 5.
The above, only the utility model preferred embodiment, therefore the utility model enforcement can not be limited with this Scope, i.e., the equivalence changes made according to the utility model claim and description and modification, all should still belong to this reality In the range of being covered with new patent.
