Abstract
The technical scheme of the utility mould is that a fast-changed structure of a die-casting mould core is provided. The fast-changed structure comprises a mould frame, a movable mould, a fixed mould and a mould core, an ejection hole is arranged on the mould frame, the ejection hole extends to the bottom of the mould core, a locking bolt is arranged in the ejection hole, the locking bolt is in threaded connection with the ejection hole, and the locking bolt abuts against the bottom portion of the mould core.
Description
Technical field:
The utility model relates to a kind of compression mod core quick change construction.
Background technology:
In the prior art, the core of compression mod is installed between mill frame and the active and inactive mold, and is fixed by active and inactive mold; In use, need change the core of wearing and tearing, but owing to core is compressed by active and inactive mold; Changing core in the existing structure needs earlier active and inactive mold to be removed, and could core be taken out, cumbersome; Replacing, the maintenance time of core are longer, are unfavorable for enhancing productivity.
The utility model content:
For solving above-mentioned technical problem, the utility model provides a kind of compression mod core quick change construction that core is changed, keeped in repair of being convenient to.
The technical scheme of the utility model is; A kind of compression mod core quick change construction with following structure is provided, and it comprises framed, active and inactive mold and core; The framed ejection hole that is provided with; The ejection hole extends to the bottom of core, and ejection is provided with clamping screw in the hole, and clamping screw is threaded with the ejection hole and offsets with the bottom of core.
After adopting said structure, the utlity model has following advantage:
On framed, be provided with after the ejection hole, when operate as normal, can core be held through clamping screw, and when needs are changed or keeped in repair core; Only need clamping screw be back-outed and can core be taken out; Need not active and inactive mold is pulled down, easy and simple to handle, help enhancing productivity.
As improvement, it also comprises lock washer, and lock washer is between clamping screw and core.Set up lock washer and help when clamping screw is installed, keeping the stable of core, not screwing of clamping screw can cause interference to core.
Description of drawings:
Fig. 1 is the mounting structure of core in the compression mod;
Fig. 2 is the sketch map of the utility model compression mod core quick change construction;
Fig. 3 is the structural representation of lock washer in the utility model compression mod core quick change construction;
The specific embodiment:
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Comparison diagram 1, Fig. 2 can know, the utility model compression mod core quick change construction, and it comprises framed 1; Active and inactive mold 2 and core 3 are provided with ejection hole 4 with core 3 corresponding positions on framed 1, ejection hole 4 extends to the bottom of core 3; Be provided with clamping screw 5 in the ejection hole 4; The front end of ejection bolt 5 is a polished rod, and afterbody is provided with screw thread, and clamping screw 5 is threaded with ejection hole 4 and offsets with the bottom of core 3.So just can core 3 is fixing.Just can be in the time of need changing or keep in repair core 3 with core 3 taking-ups as long as clamping screw 5 is back-outed, operation is very easy.
For preventing that clamping screw 5 from can cause interference to core 3 when mounted, the utility model also comprises lock washer 6, and is as shown in Figure 3, and lock washer 6 just can avoid core 3 to receive interference between clamping screw and core 3.
