Abstract
The utility model relates to a replacement structure of a die mould core. The replacement structure comprises a mould core; the mould core is arranged in a mould core hole inside a nesting block in a penetrating manner; the nesting block is fixedly arranged on a sleeve board; a through hole straightly passing through the mould core hole is formed on the sleeve board; the outer end of the through hole is sealed by a pressing board fixedly arranged on the sleeve board; a supporting rod is arranged inside the through hole; both ends of the supporting rod are respectively abutted against the mould core and the pressing board; and the aperture of the through hole is greater than the external diameter of the mould core. With the adoption of the replacement structure of the die mould core provided by the utility model, the mould core is replaced only by taking out the supporting rod after dismounting the pressing board without detaching the nesting block from the sleeve board, so that the maintenance time of a die is greatly shortened, the labor strength is reduced, and the efficiency is improved.
Description
Technical field
The utility model relates to mould, relates in particular to a kind of replacing structure of mold cores.
Background technology
Compression mod is made up of two major parts of fixed half and moving half; The cavity that cover half and dynamic model close up back formation is commonly referred to die cavity; And the part that constitutes die cavity is forming part, and forming part comprises to be inserted and core, and core is used for hole or special-shaped shape above the diecast parts.Because the working environment of die casting is more abominable, in casting process, core is destroyed through regular meeting, belongs to the easy-consuming fitting on the die casting.This just needs the replacing of core simple, convenience, to save time and to reduce labor intensity.Must take apart a die after the existing mold core fractures, striking down inserts could change core, and maintenance time, length wasted time and energy, and influence is produced.
The utility model content
The utility model technical problem to be solved provides a kind of replacing structure of mold cores, overcomes the above-mentioned technical problem that exists in the prior art.
The utility model adopts following technical scheme:
A kind of replacing structure of mold cores comprises core, in the cored hole in said core is located in and inserts; Said inserting is fixed on the cage plate; Said cage plate is provided with the through hole that connects with said cored hole straight line, and the outer end of through hole is provided with support bar by the pressing plate sealing that is fixed on the said cage plate in the through hole; Conflict with said core and pressing plate respectively in the support bar two ends, and said through-hole aperture is greater than the core external diameter.
Further, said cage plate is provided with a groove, and said groove communicates with said through hole, and said pressing plate is fixed in the said groove.
Further, said follower bolt is connected in the said groove.
Through above technical scheme, the utility model need not to take out support bar with inserting and cage plate is taken apart as long as pressing plate is pulled down the back, can change core, has shortened the repair time of mould greatly, reduces labour intensity, raises the efficiency.
Description of drawings
Fig. 1 is that the core of cover half is changed structural representation;
Fig. 2 is that the core of dynamic model is changed structural representation.
The specific embodiment
Combine accompanying drawing that the utility model is further described now.The sketch map that these accompanying drawings are simplification is only explained the basic structure of the utility model in a schematic way, so it only shows the formation relevant with the utility model.
The replacing structure of a kind of mold cores of the utility model comprises that the core on the cover half is changed the core replacing structure (shown in Figure 2) on structure (shown in Figure 1) and the dynamic model.Structure, principle that core on dynamic model, the cover half is changed structure are identical, below in conjunction with the accompanying drawing further explain.Core 1 is located in the cored hole of inserting in 2; Insert and 2 be fixed on the cage plate 3; Cage plate 3 is provided with the through hole that connects with the cored hole straight line, and the outer end of through hole is provided with support bar 5 by pressing plate 4 sealings that are fixed on the cage plate 3 in the through hole; Conflict with core 1 and pressing plate 4 respectively in the support bar two ends, and through-hole aperture is greater than the core external diameter.During maintenance, need not inserting and cage plate is taken apart, only need pressing plate is pulled down, take out support bar then, core can take out, and the mold cores of the utility model is changed structure, makes things convenient for the taking-up of core, and is time saving and energy saving.
Present embodiment is through being provided with a groove on the cage plate, groove communicates with through hole, and pressing plate 4 bolts are connected in the groove.At first unload bolt during dismounting and pull down pressing plate 4 because support bar 5 only play a part restriction core 1 along the hole to moving, so be matched in clearance between support bar 5 and through hole, inclined mould can make support bar 5 skid off.In mold cavity, knock core 1 then, make that core 1 is stressed to be moved in cored hole and through hole, can accomplish the replacing of core.The utility model is not limited to compression mod, and the similar mould of structure all can be used the utility model.
More than the replacing structure of a kind of mold cores that the utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; According to the thought of the utility model embodiment, the part that on the specific embodiment and range of application, all can change, in sum; This description should not be construed as the restriction to the utility model, and all any changes of being made according to the utility model design philosophy are all within the protection domain of the utility model.
