Abstract
The utility model relates to a modular ejector pin, including loop bar, driving lever, driven lever and sealing washer, the loop bar is the member of an inside cavity both ends trompil, and driving lever and driven lever are do not pegged graft in the trompil at loop bar both ends, and the junction of driving lever and driven lever and loop bar is provided with the sealing washer respectively. Utilize hydraulic drive, the utility model discloses the ejector pin divides traditional ejector pin for two parts that do not contact each other for the ejector pin still has fine stability, smooth ejecting product in the great mould of depth.
Description
Technical field
This utility model relates to a kind of push rod, particularly relates to a kind of mould inside push rod for ejecting product.
Background technology
After mould product molding, for the smooth demoulding of product, it is necessary to adopt a kind of ejecting mechanism to be ejected in mould by product.Fig. 1 is a kind of common mechanical type ejecting mechanism operation principle schematic diagram in mould, and guide pillar 5 drives top board 6 to drive push rod 7 to move upward ejecting product 8.
This traditional ejecting mechanism simple structure, uses extensively, but this ejecting mechanism is not suitable for the mould that depth is bigger.Because the motion that long push rod is in mould is unstable, eject difficulty.
Utility model content
The technical problems to be solved in the utility model is: the problem ejecting difficulty in order to solve tradition push rod in the mould that depth is bigger, and this utility model provides a kind of combined push rod to solve the problems referred to above.
This utility model solves its technical problem and be the technical scheme is that a kind of combined push rod, including loop bar, driving lever, follower lever and sealing ring, loop bar is the rod member of an inner hollow two ends perforate, driving lever and follower lever are plugged in the perforate at loop bar two ends respectively, and the junction of driving lever and follower lever and loop bar is respectively arranged with sealing ring.
Optimizing further, loop bar is two-part structure, is the hollow rods of open at one end one end perforate including loop bar epimere and loop bar hypomere, loop bar epimere and loop bar hypomere, and the opening end relative combinations of loop bar epimere and loop bar hypomere forms loop bar.
Optimize further, loop bar hypomere is provided with mounting seat, mounting seat is provided with installing hole.
Optimize further, loop bar epimere is provided with oil filler.
Optimize further, driving lever and be provided with external screw thread on follower lever.
Optimize further, driving lever and be provided with scale on follower lever.
The beneficial effects of the utility model are: (1) this utility model combined push rod utilizes hydraulic drive, traditional push rod has been divided into two parts not contacted with each other, push rod is made still to have good stability, smooth ejecting product in the mould that depth is bigger.
(2) loop bar of this utility model push rod is that two-part structure, ease of assembly, and versatility are better.
(3) loop bar of this utility model push rod is provided with mounting seat and installing hole, facilitates the installation of push rod.
(4) driving lever of this utility model push rod and follower lever are provided with external screw thread, facilitate push rod to be connected with top board and jacking block.
(5) driving lever of this utility model push rod and follower lever are provided with scale, the stroke of driving lever and follower lever is set during push rod convenient for assembly.

Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in further detail.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the composition relevant with this utility model.
(embodiment 1)
As shown in Figures 2 and 3, the combined push rod of the present embodiment includes loop bar 1, driving lever 2, follower lever 3 and sealing ring 4, loop bar 1 is two-part structure, including loop bar epimere 11 and loop bar hypomere 12, loop bar epimere 11 and loop bar hypomere 12 are the hollow rods of open at one end one end perforate, the opening end of loop bar epimere 11 and loop bar hypomere 12 is respectively arranged with external screw thread and female thread, and connect relative with the opening end of loop bar hypomere 12 of loop bar epimere 11 is combined into complete loop bar 1；Loop bar epimere 11 is provided with oil filler 14, loop bar hypomere 12 is provided with mounting seat 13, mounting seat 13 is provided with installing hole, bolt can be utilized to be arranged on mould by loop bar 1 by installing hole.
Driving lever 2 and follower lever 3 are cylindrical rod piece, driving lever 2 and follower lever 3 are provided with external screw thread and scale, driving lever 2 and follower lever 3 are plugged in the perforate at loop bar 1 two ends respectively, and the junction of driving lever 2 and follower lever 3 and loop bar 1 is respectively arranged with sealing ring 4.
Driving lever 2 is connected with top board 6, and follower lever 3 is connected with jacking block 9, and the inside of loop bar 1 is full of hydraulic medium.During die sinking, top board 6 moves upward under the driving of guide pillar 5, and driving lever 2 extrudes hydraulic medium, and follower lever 3 moves upward under the effect of hydraulic medium and utilizes jacking block 9 ejecting product 8.The length of driving lever 2 and follower lever 3 is fixing, and not by the impact of the mould longitudinal direction degree of depth, thus the combined push rod of the present embodiment is being applied in the mould that longitudinal degree of depth is big still have good stability.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not necessarily departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content in description, it is necessary to determine its technical scope according to right.
