Description

A kind of floating occlusion molding machine
Technical field
The utility model relates to forging molding technical field, specially a kind of floating occludes molding machine.
Background technique
Forging with branch type as shown in Fig. 6 in forging molding at present, typically uses open die forging, impressing forging, in open type Impression periphery is equipped with flash gutters, and in forging process, extra metal can be flowed into flash gutters, due to using open die forging, impressing forging, molding When branch at the top of be easy to appear that filling is discontented to be caused to lack material, in order to guarantee that branch tip can be filled with, generally require to increase base The weight of material, so utilization rate of raw materials is just at a fairly low, causes a large amount of wastes of raw material, and than same projection area Regular forging need the forging equipment of large-tonnage to be just able to satisfy molding needs, energy consumption is high.
Summary of the invention
The purpose of this utility model is to provide a kind of floatings to occlude molding machine, has structure simple, stability is good, fills The high advantage of filling out property good material utilization rate, solves the problems of the prior art.
To achieve the above object, the utility model provides the following technical solutions: a kind of floating occlusion molding machine, including upper Bottom plate 1, lower plate 20,1 lower end surface of upper plate are fixedly installed with cope plate 2, the lower plate by upper locking clamping block 16 20 upper surfaces are fixedly installed with lower template 13 by lower locking clamping block 15, and the cope plate 2 is fixedly installed big guide sleeve 3, described Lower template 13 is equipped with the big guide post 14 with big 3 slide fit of guide sleeve, and the 2 lower end surface center of cope plate is fixedly installed with upper mold Tool 4,13 upper surface of lower template are fixedly installed with fixed board 21, are equipped with float plate 6, the float plate 6 above the fixed board 21 On the lower mold 5 being adapted to the upper mold 4 is installed, the lower mold 5 is equipped with the jogger hole 501 penetrated through with type chamber, described Molding mandril 10 is fitted in jogger hole 501, molding 10 lower end of mandril passes through the relief hole being arranged on the fixed board 21 2101,10 lower end surface of molding mandril and the 13 upper end face contact of lower template;Between the fixed board 21 and the float plate 6 The first elastomer 8, the second elastomer 9 and third elastomer 17 are provided with, during first elastomer 8 and third elastomer 17 be Empty shape elastomer, left and right ends gap is fitted with guide bar bolt 7 in the float plate 6, and the every guide bar bolt 7 is each passed through It one corresponding first elastomer 8 and is connect with the fixed board 21, by the flange of 7 upper end of guide bar bolt to described floating The upward position of movable plate 6 is limited;The float plate 6 is also fixedly installed with small guide sleeve 19, and the small guide sleeve 19 is pacified with fixed 18 slide fit of small guide rod on the fixed board 21 and across 17 center of third elastomer, the small guide rod 18 is to described floating The up and down motion of movable plate 6 is oriented to;Second elastomer 9 has 4 in rectangle and is symmetrically distributed in the molding mandril 10 Surrounding.
Upper plate 1, lower plate 20 are connect with to the sliding block lower end surface of press machine and bottom plate respectively through the above arrangement, pacified It fills convenient and efficient;Upper plate 1 rises under the drive of press ram and separates upper mold 4 and lower mold 5 when forging molding, this At present mold 5 rises under the first elastomer 8, the second elastomer 9 and third elastomer 17 synergistic effect with float plate 6, and by The flange of 7 upper end of guide bar bolt limits the upward position of float plate 6 and is namely limited the extreme higher position of lower mold 5 Position carries out accurate guiding in 6 uplink Shi You little guide sleeve 19 of float plate and 18 mating reaction of small guide rod;When upper mold 4 and lower mold 5 Would be heated to after completely separable initial forging temperature blank 22 be put into lower mold 5 type it is intracavitary, by 10 upper surface of molding mandril carry out Support, then press ram drives 1 downlink of upper plate, so that upper mold 4 and lower mold 5 be made to be closed, blank 22 is enclosed in The type of upper mold 4 and lower mold 5 is intracavitary;The first elastomer 8, the second elastomer 9 when press machine drives upper plate 1 to continue traveling downwardly The drag generated with third elastomer 17 makes upper mold 4 and lower 5 tight closure of mold, and lower mold 5 and float plate 6 are simultaneously With 4 downlink of upper mold, at this moment will not be moved down due to molding 10 lower end surface of mandril with 13 upper end face contact of lower template, this is with regard to phase When deeply playing the type of mold 5 intracavitary in the upper surface of molding mandril 10, the material of blank 22 is squeezed into upper mold 4 and lower mold Each forming part is filled in 5 type chamber, and, in the process due to upper mold 4 and lower 5 tight closure of mold, material will not flow for this Outside to mold, type chamber can only be filled, therefore fullness is good, external form is full after forging molding, and will not generate winged Side, so save raw material, improve utilization rate of raw materials, simultaneously because without overlap, and be by molding mandril 10 to base Material 22 carries out squeeze pack, and molding projected area is small, and required forming force is small;First elastomer 8, the second elastomer 9 and third bullet Property body 17 be independently arranged, thermal diffusivity is good, and the heat that the heat of blank and deformation generate when avoiding hot-forging forming is to the first elasticity Body 8, the second elastomer 9 and third elastomer 17 have an impact, and improve the stability of elastomer;Second elastomer 9 has 4 Rectangle and it is symmetrically distributed in the support force balance and stability that generates to float plate of molding 10 surrounding of mandril, it is ensured that upper mold 4 and lower die Closely stablize when 5 closure of tool.
It is further: it is coaxially provided with first step hole 1301 in the lower template 13 with the molding mandril 10, described The first push rod 11 is fitted in one stepped hole 1301,11 upper surface of the first push rod is concordant with 13 upper surface of lower template.
