Description
Technical field
The utility model relates to die casting technical field, particularly relates to the compression mod spiral core-pulling mechanism for die casting.
Background technology
Die casting is a large class in mould, and it is a kind of method of casting liquid forging, a kind of technique completed on special die casting die forging machine.Its basic craft course is: the first low speed of molten metal or high-speed casting fill in the die cavity of type progressive die tool, mould has movable cavity surface, it, along with the cooling procedure pressurization forging of molten metal, had both been eliminated the shrinkage porosity defect of contraction cavity of blank, and had also made the interior tissue of blank reach the Broken Crystal of forging state.Along with developing rapidly of China's automobile and motorcycle industry, Die Casting Industry has welcome the new period of development, also has higher requirement to the comprehensive mechanical property, life-span etc. of die casting meanwhile.
For partial lumen helical structure alloy product, existing die casting core-pulling mechanism cannot direct core_pulling demoulding and should not adopt aft-loaded airfoil pattern, and Product processing cost is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of compression mod spiral core-pulling mechanism for the deficiencies in the prior art, can direct core_pulling demoulding, reduces Product processing cost.
For achieving the above object, the utility model adopts following technical scheme.
Compression mod spiral core-pulling mechanism, it comprises slider head, fairlead, take-up housing and oil cylinder, and one end of described slider head is arranged with bearing, bearing is fastened on take-up housing, hydraulic oil cylinder driving connection sliding block seat, fairlead fixed cover is located at slider head stage casing, and fairlead offers spiral guide slot.
Described fairlead is located at slider head stage casing by screw fixed cover.
It also comprises holder, and holder encases fairlead.
The utility model beneficial effect is: a kind of compression mod spiral core-pulling mechanism described in the utility model, can direct core_pulling demoulding, reduces Product processing cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, compression mod spiral core-pulling mechanism described in the utility model, it comprises slider head 2, fairlead 3, take-up housing and oil cylinder, one end of described slider head 2 is arranged with bearing 4, bearing 4 is fastened on take-up housing, hydraulic oil cylinder driving connection sliding block seat, fairlead 3 fixed cover is located at slider head 2 stage casing, and fairlead 3 offers spiral guide slot.Further, described fairlead 3 is located at slider head 2 stage casing by screw fixed cover, is convenient to installing/dismounting.Further, described compression mod spiral core-pulling mechanism also comprises holder 5, and holder 5 encases fairlead 3, and holder 5 is installed on mold base 1.
The operation principle of this mechanism is: utilize oil cylinder to drive take-up housing, and under the drive of oil cylinder, bearing 4 rotates and produces twitch force, and fairlead 3 provides guide effect, makes to loose core energy smoothly along the hand of spiral demoulding.Then because of compression mod high temperature, high strength and easily produce and fly material and block spiral guide slot, so encase and protect fairlead 3 with holder 5, and be fixed on mold base.
The advantage of compression mod spiral core-pulling mechanism described in the utility model is: spiral is loosed core and product just disposablely can be formed out helical structure when die casting, solution cannot a direct core_pulling demoulding difficult problem, and save Product processing cost, this agency cost is low simultaneously, stability is high, durability is strong, is the pretty good selection mode of die casting screw mechanism.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
