Abstract
The utility model provides a combined closed die. The die consists of three parts which are connected in sequence, namely, an outer ferrule, a middle ferrule and a die core, wherein the die core is arranged on the middle part, and has a lug structure consisting of at least two layers; the middle ferrule and the outer ferrule sleeve the die core in sequence. Due to the adoption of a combined structure, the outer ferrule, the middle ferrule and the die core are independent of one another and can be matched with one another, so that the deformation and expansion coefficients of the die are increased, and the problem of die cracking is solved completely. The machining way (ordinary lathe machining) is changed, and the machining cost is lowered. Moreover, the outer ferrule is changed to be made of 5CrNiMo material, so that the cost of die material is reduced.
Description
Technical field
The utility model relates to forging molding field, refers to especially a kind of combined type closed molds.
Background technology
At present, domestic existing closed molds is monolithic construction, and originally uses the overall H13 die steel module of Φ 420 × 180, and this module must be formed by Cutter Body Processing with Machining Center, and cavity dimension is Φ 200 × 48.9mm; In production and application process, because mould carries stressedly repeatedly, break in Φ 200 root generation fractures by fatigue, cause a whole set of mould to be scrapped.Therefore producer has to adopt increase number of molds to ensure Production requirement, has so greatly increased production cost.
Utility model content
The utility model proposes a kind of combined type closed molds, solve mould fracture by fatigue problem, improve die life.
The technical solution of the utility model is achieved in that a kind of combined type closed molds, described mould is made up of three parts that connect successively, comprise outer collar, middle lasso and core rod, described core rod is arranged on middle part, for at least two layers of boss structure, described middle lasso and outer collar are set on core rod successively.
As preferably, described core rod is two-layer coaxial round platform combining structure, comprises core rod upper strata and core rod bottom, and two-layer one-body molded.
As preferably, described middle lasso is set in core rod upper strata; Described outer collar is set in core rod bottom, and coordinates with the outer edge of being trapped.
As preferably, described outer collar is of a size of (Φ 420-Φ 280) × 180, adopts 5CrNiMo material.
As preferably, described middle lasso is of a size of (Φ 280-Φ 180) × 90, adopts H13 die steel material.
As preferably, described core rod is of a size of (Φ 310 × 60)+(Φ 220 × 60), adopts H13 die steel material.
Compared with prior art, the utility model has the advantage of: adopt fabricated structure, outer collar, middle lasso and core rod are relatively independent, can coordinate again, increase die deformation and the coefficient of expansion, thoroughly solved mold breakdown problem.Change processing mode (engine lathe processing), cut down finished cost.And outer collar changes 5CrNiMo material into, save mold materials cost.
Brief description of the drawings
Fig. 1 is that master of the present utility model looks cutaway view.
In figure: 1, core rod; 2, middle lasso; 3, outer collar; 11, core rod upper strata; 12, core rod bottom.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment: referring to Fig. 1, a kind of combined type closed molds, described mould is made up of three parts that connect successively, comprise outer collar 3, middle lasso 2 and core rod 1, described core rod 1 is arranged on middle part, is at least two layers of boss structure, and described middle lasso 2 and outer collar 3 are set on core rod 1 successively.
As preferably, described core rod 1 is two-layer coaxial round platform combining structure, comprises core rod upper strata 11 and core rod bottom 12, and two-layer one-body molded.
As preferably, described middle lasso 2 is set in core rod upper strata 11; Described outer collar 3 is set in core rod bottom 12, and coordinates with the outer edge of being trapped.
As preferably, described outer collar 3 is of a size of (Φ 420-Φ 280) × 180, adopts 5CrNiMo material.
As preferably, described middle lasso 2 is of a size of (Φ 280-Φ 180) × 90, adopts H13 die steel material.
As preferably, described core rod 1 is of a size of (Φ 310 × 60)+(Φ 220 × 60), adopts H13 die steel material.
The utility model adopts fabricated structure, and outer collar 3, middle lasso 2 and core rod 1 are relatively independent, can coordinate again, increases die deformation and the coefficient of expansion, has thoroughly solved mold breakdown problem; Even if one of them damages, also can split the part coming to damaging and change or keep in repair.And outer collar 3 changes 5CrNiMo material into, this material cost, lower than H13 mould steel, is ensureing, under the constant prerequisite of outer collar 3 durabilities and other performance, to have saved mold materials cost.And having changed processing mode, above processing mode all available engine lathe completes, and carrying out hot charging and join the whole manufacturing procedure that just completes mould after heating, does not need to complete with machining center; After above three parts being extruded when wherein arbitrary part damage is reprocessed, directly can be complete with lathe processing, one-tenth provides cost savings.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
