Produce the mould balance device of muffler
The utility model relates to mold machining technology, is specifically related to a kind of mould balance device producing muffler.
Mould is commercial various mould and the instrument obtaining required product with methods such as injection moulding, blowing, die casting or forging forming, smelting, punching press, stretchings of industrial production, general mould comprises two board molds, i.e. dynamic model and cover half, part die cavity is at dynamic model, another part die cavity is at cover half, the two partable, takes out product time separately, makes blank inject mold cavity and be shaped when closing up.Shaping shape of product moulded by mould, size equal-specification has certain standard, requires that all products are balanced consistent, occurs that the product of distortion can only be scrapped.In prior art, after dynamic model drives Motion and repose mould fastening by stamping machine, buckling surface is easy to occur the phenomenon that is uneven, and does not also have the special equipment for buckling surface balancing in prior art, and the inferior rate of such finished product is higher.In addition, the elasticity of mould matched moulds should to ensure during injection moulding that blank mold exhaust clearance has enough spaces, and then do not produce blank mold overlap situation and occur, this just needs the height of finely tuning moving platen, has made matched moulds elasticity reasonable, appropriate.And also there is no a high-precision balanced adjustment equipment at present in prior art.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art part, a kind of mould balance device producing muffler is provided, this apparatus structure simplicity of design, rationally, after mould dynamic model and quiet mould fasten, pass through rotary handle, can the high-precision adjustment dynamic model degree of balance of placing, prevent the phenomenon that is uneven, simple to operate, quick.
For achieving the above object, the utility model adopts following technical scheme: a kind of mould balance device producing muffler, comprise dynamic model, quiet mould and base, in base bottom, screw rod on two is at least vertically installed, dynamic model is provided with lower screw rod with upper screw rod correspondence position, and described upper and lower screw rod is reverse thread, between upper and lower screw rod, be provided with handle, described handle upper portion is set with by top nut and upper screw rod, and lower portion thereof is set with by lower nut and lower screw rod.
Based on technique scheme, described dynamic model, quiet mould and base are square structure, in base bottom, four Angle Position are vertically provided with screw rod on four, are vertically provided with the lower screw rod corresponding with upper screw rod at four Angle Position of dynamic model, are all provided with handle between described each upper and lower screw rod.
Based on technique scheme, in order to adjust the dynamic model degree of balance more flexibly, widely, also sleeve structure is provided with between base and upper screw rod, be specially: be fixed with outer tube in base bottom, on upper screw rod top, inner sleeve is installed, inner sleeve is set in outer tube, and is provided with locking nut.
Based on technique scheme, be also provided with positioning head in lower screw rod end.
Beneficial effect: the mould balance device of production muffler of the present utility model, pass through rotary handle, can local directed complete set dynamic model height, targetedly rugged mould land area is finely tuned, ensure the whole machine balancing of matched moulds, to improve product percent of pass, structure is simple, easy to use, flexible, degree of regulation is high, highly promotion and implementation.
Accompanying drawing explanation
Fig. 1 is the mould balance apparatus structure schematic diagram that the utility model produces muffler;
Fig. 2 is the mould balance apparatus structure schematic diagram that the utility model another kind produces muffler.
Number in the figure: 1 is dynamic model, 2 is quiet mould, and 3 is base, and 4 is handle, and 5 is top nut, and 6 is lower nut, and 7 is upper screw rod, and 8 is lower screw rod, and 9 is positioning head, and 10 is holder, and 11 is outer tube, and 12 is inner sleeve, and 13 is locking nut.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment 1: a kind of mould balance device producing muffler, see Fig. 1, comprise dynamic model 1, quiet mould 2 and base 3, dynamic model 1, quiet mould 2 and base 3 are square structure, four, base 1 bottom, Angle Position is vertically provided with screw rod 7 on four downwards, and upper screw rod 7 is fixed on base by holder 10.Vertically upwards be provided with the lower screw rod 8 corresponding with upper screw rod 7 at dynamic model 1 four Angle Position, described upper and lower screw rod is reverse thread.Between upper and lower screw rod, be provided with handle 4, described handle 4 top is set with by top nut 5 and upper screw rod 7, and bottom is set with by lower nut 6 and lower screw rod 8.Have positioning head 9 at lower screw rod end winding support, to prevent rotatable handle excessive, dynamic model comes off.The present embodiment is the equipment adjusting the mould matched moulds degree of balance and elasticity specially, after dynamic model drives Motion and repose mould fastening by stamping machine, due to the unstability of driving force, moving platen face is easy to occur locally being uneven phenomenon, the elasticity fastened with quiet mould also there will be pine, tension phenomenon, this is easy to make defect ware, this just needs the whole machine balancing degree adjusting dynamic model, higher place, handle is rotated down at its correspondence position, higher position moves down, otherwise, handle is reversely rotated in place on the low side, position on the low side is moved, due to nut, screw rod is fine thread, all height fine adjusting function can be realized, pass through local modulation, finally realize whole machine balancing, matched moulds elasticity also can adopt the method to regulate.
Embodiment 2: the another kind of mould balance device producing muffler, see Fig. 2, the present embodiment content is substantially identical with embodiment 1 content, same section content no longer repeats, as different from Example 1: the present embodiment is also provided with sleeve structure between base 1 and upper screw rod 7, is specially: be fixed with outer tube 11 in base 1 bottom, on upper screw rod top, inner sleeve 12 is installed, inner sleeve 12 is set in outer tube 11, and cannula tip position is provided with locking nut 13 outside.This embodiment increases the scope highly regulated, and on dynamic model balanced adjustment, the scope of application is wider.
