Description
Technical field
The utility model relates to die casting field, and specifically a kind of compression mod is loosed core and oil cylinder syndeton.
Background technology
In typical structure of cast die, slide and slide block and loose core with the connected mode of oil cylinder for tradition " Hough " is connected, in structure of cast die, tradition " Hough " syndeton connects slide by two " Hough " one end or looses core, the other end connects oil cylinder piston head and forms, and two " Hough " is fixed into a cylinder by four hexagon socket head cap screws again.This employing " Hough " connects looses core and the connected mode of oil cylinder, owing to often doing a mould, loose core and all will complete the process of once insertion and withdrawing in a mold, through the folding mould of ten million time, four hexagon socket head cap screws fixing two " Houghs " very easily loosen, and then make " Hough " extremely stressed and rupture, change frequent, production is obstructed.This " Hough " comparison bothers, and first wants Vehicle Processing, auger shell keyhole, milling bolt cap heavy stand, finally needs to adopt Linear cut to cut open.Also easily rupture in the connection neck place of oil cylinder in addition, needs to change whole cylinder piston rod during reparation, just can reuse after joining sealing ring debugging.
Therefore, for overcoming the above problems, need on a kind of making easier, faster during replacing, the high compression mod of bonding strength is loosed core and oil cylinder syndeton.
Utility model content
In view of this, the purpose of this utility model overcomes defect of the prior art, there is provided easier on a kind of making, faster during replacing, bonding strength is high, from cost, efficiency, processing technology and rapid wear degree, the compression mod that its performance is significantly increased is loosed core and oil cylinder syndeton;
Compression mod of the present utility model is loosed core and oil cylinder syndeton, comprises loose core joint and the cylinder connector that is connected with oil cylinder cover piston rod of loosing core that are connected with slide; Described joint of loosing core is connected by monoblock type connector with cylinder connector; Described joint the inner of loosing core is provided with inward flange, and integral joint is provided with and coordinates with described inward flange and embedded groove for carrying out axial location to described inward flange;
Further, described cylinder connector the inner is provided with the section of being threaded, and described integral joint is provided with the screwed hole coordinated with the described section of being threaded;
Further, joint outer end of loosing core described in is provided with outward flange;
Further, cushion pad is provided with between described inward flange end face and embedded groove;
Further, described screwed hole the inner is communicated with embedded groove;
Further, described screwed hole is coaxial with described joint of loosing core.
The beneficial effects of the utility model are: compression mod of the present utility model is loosed core and oil cylinder syndeton, loose core joint and cylinder connector passes through integral joint connection, integral joint is monolithic construction, when connecting, the flange of loosing core on joint can radially snap in embedded groove, the joint that makes to loose core is relative fixing vertically with integral joint, cylinder connector can adopt the version same with joint of loosing core and integral joint connection, or adopt screw thread to be fixedly connected with integral joint, compare the Hough connector of existing employing, integral joint is assembled without the need to adopting the securing member of bolt, its structural strength is higher, in core-pulling mechanism During Process of Long-term Operation, be difficult to destroy, its service life is higher, on the other hand, integral joint is in processing and making process, do not need to utilize Linear cut to cut open, greatly reduce processing cost.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model, and as shown in the figure, the compression mod in the present embodiment is loosed core and oil cylinder syndeton, comprises loose core joint 8 and the cylinder connector 2 that is connected with oil cylinder cover piston rod of loosing core that are connected with slide, described joint 8 of loosing core is connected by monoblock type connector with cylinder connector 2, described joint 8 the inner of loosing core is provided with inward flange 5, integral joint 3 is provided with and coordinates with described inward flange 5 and embedded groove 4 for carrying out axial location to described inward flange 5, integral joint 3 is monolithic construction, when connecting, the flange of loosing core on joint 8 can radially snap in embedded groove 4, the joint 8 that makes to loose core is relative fixing vertically with integral joint 3, cylinder connector 2 can adopt the version same with joint 8 of loosing core to be connected with integral joint 3, or adopt screw thread to be fixedly connected with integral joint 3, compare the Hough connector of existing employing, integral joint 3 is assembled without the need to adopting the securing member of bolt, its structural strength is higher, in core-pulling mechanism During Process of Long-term Operation, be difficult to destroy, its service life is higher, on the other hand, integral joint 3 is in processing and making process, do not need to utilize Linear cut to cut open, greatly reduce processing cost.
In the present embodiment, described cylinder connector 2 the inner is provided with the section of being threaded, described integral joint 3 is provided with the screwed hole 7 coordinated with the described section of being threaded, owing to loosing core, joint 8 coordinates clamping by flange with embedded groove 4 with monolithic construction, therefore, joint 8 of loosing core can slip off in radial direction with monolithic construction, make Joint failure, therefore, cylinder connector 2 adopts screw thread to be fixedly connected with integral joint 3, effectively can avoid integral joint 3 radially landing, another side, when assembling, first can be fixedly connected with cylinder connector 2 and integral joint 3, pulled core structure is embedded in the embedded groove 4 of integral joint 3.
In the present embodiment, described in joint 8 outer end of loosing core be provided with outward flange 1, outward flange 1 can arrange bolt hole etc., utilize outward flange 1 joint 8 that makes to loose core to be fixedly connected with slide or core.
In the present embodiment, cushion pad 6 is provided with between described inward flange 5 end face and embedded groove 4, for ensureing that inward flange 5 can be embedded in embedded groove 4 smoothly, the width of embedded groove 4 is greater than the width of inward flange 5 usually slightly, therefore, after joint 8 of loosing core is connected with integral joint 3, gap is there is between its end face and embedded groove 4, in the process of loosing core, loose core between joint 8 and integral joint 3 and rigid collision can occur, therefore, be provided with cushion pad 6 between inward flange 5 end face and embedded groove 4 and can slow down this impact stating, improve the service life of integral joint 3 and joint 8 of loosing core.
In the present embodiment, described screwed hole 7 the inner is communicated with embedded groove 4, make in processing integral joint 3, a through hole can be directly got out along axis, and carry out reaming in through hole side and make it coordinate with joint 8 of loosing core, through hole opposite side thread mill drilling 7, this version can improve the axiality of loose core joint and cylinder connector 2 greatly.
In the present embodiment, described screwed hole 7 is coaxial with described joint 8 of loosing core, and this arrangement form can ensure that integral joint 3 can not produce turning torque in the course of the work, improves its stability.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
