Abstract
The invention provides a large combined dual-jacking mould structure. The large combined dual-jacking mould structure can solve the problem that an upper mould cannot perform demoulding when an existing single-jacking mould is used for forging a large deep-cavity thin-walled forge piece. The large combined dual-jacking mould structure is simple and convenient to process and assemble; and the upper mould and a lower mould can both achieve demoulding of the forge piece in a jacking mode. The large combined dual-jacking mould structure comprises an upper mould structure and a lower mould structure; the upper mould structure comprises an upper mould base and the upper mould, wherein the upper mould is mounted beneath the upper mould base; a lower mould jacking mechanism is mounted in the lower mould structure. The large combined dual-jacking mould structure is characterized in that an upper mould jacking mechanism is mounted in the upper mould structure; the upper mould jacking mechanism comprises an upper jacking rod and a compression spring; the upper jacking rod sequentially penetrates through the upper mould and an upper jacking rod mounting hole of the upper mould base from bottom to top; the flange at the bottom of the upper jacking rod is in clearance fit with a groove of the upper mould; the diameter of the upper jacking rod mounting hole of the upper mould base is larger than that of an upper jacking rod mounting hole of the upper mould; the part, located in the upper jacking rod mounting hole of the upper mould base, of the upper jacking rod is sleeved with the compression spring which is locked on the top surface of the upper mould through a tight nut and a flat washer.
Description
Technical field
The present invention relates to moulding forging mold structure field, be specially large-scale combined Double Tops and go out mould structure.
Background technology
Its mould of the forging of general depanning difficulty is adopted to single lower ejection die mostly, be in mould, to be only provided with a lower ejecting mechanism, thereby forging can only upwards be ejected and be made forging demoulding by this lower ejecting mechanism, but to some special forging as large-scale deep-cavity thin-wall forging, forging both can cannot go out counterdie because die cavity is high, can easily because of cooling contraction, embrace on drift and cannot go out patrix again.Therefore, if only adopt lower ejection die for this forging, forging very easily occurs embracing mould and causes producing interruption or forging and mould and scrap, and if adopt strengthen the method for designing of draft angle often can be too high due to forging height, produce serious waste of material, stock utilization is low; In addition, general moulding forging mold is because its upper die and lower die are monolithic construction, so mold monomers pts wt is heavy, size is large, is unfavorable for rotation and the assembling of mould, and Mould Machining cost is high; And, traditional moulding forging mold, mostly its patrix and counterdie are to be directly installed on die holder, and in die forging process, upper die and lower die are stressed is prone to laterally or dislocation longitudinally, thereby has affected forging precision.
Summary of the invention
For the problems referred to above, the invention provides large-scale combined Double Tops and go out mould structure, the problem that when it can solve large-scale deep-cavity thin-wall forging and adopts ejection die under existing list to forge, patrix cannot the demoulding, it is simple in structure, it is easy to assembly to process, upper and lower mould all can be realized the ejection device to forging.
Its technical scheme is such, it comprises upper die structure and lower die structure, described upper die structure comprises upper bolster and patrix, described patrix is installed under described upper bolster, counterdie ejecting mechanism is installed in described lower die structure, it is characterized in that: knocking from up die mechanism is installed in described upper die structure, described knocking from up die mechanism comprises upper ejector pin, Compress Spring, described upper ejector pin is from bottom to top successively through described patrix, the upper ejector pin installing hole of upper bolster, the groove matched in clearance of the base flange of described upper ejector pin and described patrix, the aperture of the upper ejector pin installing hole of described upper bolster is greater than the aperture of the upper ejector pin installing hole of described patrix, the part periphery that described upper ejector pin is positioned at described upper bolster installing hole is set with described Compress Spring, described Compress Spring by clamp nut peace washer locking in described patrix end face.
It is further characterized in that:
Described patrix is positioned under described upper bolster by round pin, and between described patrix and upper bolster by T-shaped for groove bolt, packing ring and nut be connected and fixed;
Described lower die structure comprises die shoe and counterdie core rod, and described counterdie core rod is installed on lower baffle plate, and described lower baffle plate passes through square cotter location and installation on described die shoe;
Described counterdie ejecting mechanism comprises counterdie jacking block, lower push rod, described counterdie jacking block is installed in the end face groove of described counterdie core rod, and described lower push rod passes successively described die shoe, lower baffle plate from bottom to top and is connected with the bottom surface of described counterdie jacking block after counterdie core rod;
Described upper ejector pin, counterdie jacking block, lower push rod arrange with one heart;
On described lower baffle plate, have core rod locating slot, described counterdie core rod is installed in described core rod locating slot, between described counterdie core rod and described lower baffle plate, by soket head cap screw, is fastenedly connected;
Described upper die and lower die base plate, counterdie core rod, counterdie jacking block are made by any in 5CrNiMo or 5CrNiMoV material;
Described upper ejector pin, lower push rod are made by H13 material.
Beneficial effect of the present invention is:
(1) in its upper die structure, knocking from up die mechanism is installed, after die forging completes, counterdie ejecting mechanism moves upward, knocking from up die mechanism moves downward, by forging ejection device, thereby can effectively avoid the single lower ejector mechanism die forging when the demoulding of tradition to embrace the generation of the phenomenon of mould, thereby guarantee the continuity of producing and reduce mould and damage, reducing the processing rehabilitation cost of mould;
(2) its lower die structure is installed and is formed by lower baffle plate, the combination of counterdie core rod of correspondence respectively, thereby has greatly reduced weight and the size of single mould parts, has reduced Mould Machining cost, and is convenient to transhipment and the combination installation of mould parts;
(3) its upper die structure, lower die structure pass through respectively round pin, square cotter location and installation in upper bolster, die shoe, and it can effectively play the mismatch that prevents all directions, can guarantee that the quick location assembling of mould can guarantee the precision of die forging again simultaneously;
(4) its upper die and lower die base plate, counterdie core rod, counterdie jacking block are made by any in 5CrNiMo or 5CrNiMoV material, and upper ejector pin, lower push rod are all made than 5CrNiMo or the high H13 material of 5CrNiMoV material by hardness, intensity, thereby can more effectively be guaranteed the reliable demoulding of forging.
