Description
Technical field
The utility model belongs to technical field of mold, particularly a kind of pump cover shaping dies.
Background technology
At present, in the production process of pump cover, usually adopt milling machine to process plate, be processed into pump cover.Specifically, be utilize the milling cutter rotary motion of milling machine to be main motion, the movement of plate and milling cutter is feed motion, and carry out processing process to panel surface, it can processing plane, groove, also can process various curved surface, gear etc.Becoming in the process of pump cover by Sheet Metal Processing, due to the surperficial groove identical with many places shape of pump cover, milling cutter can only carry out milling successively to groove.Such processing mode makes the production efficiency of factory's pump cover low, and accuracy is not high, can not ensure product quality.
Utility model content
The purpose of this utility model is to provide a kind of structure simple pump cover 408 mould, and it can improve production efficiency and the accuracy of pump cover, can also improve the product percent of pass of pump cover, and then ensures product quality.
The purpose of this utility model is realized by such technical scheme, it includes upper bolster and die shoe, guide frame is provided with between described upper bolster and described die shoe, upper bolster is provided with shaping boss, shaping boss is provided with female die for forming, die shoe is provided with the forming terrace die matched with described female die for forming, described forming terrace die is provided with four identical projections, described female die for forming is provided with four identical grooves matched with described projection, upper bolster and die shoe involutory after, described female die for forming and described forming terrace die form closed pump cover die cavity.
The guide pillar that described guide frame comprises guide pin bushing and matches with guide pin bushing, described guide pin bushing is arranged on upper bolster, and described guide pillar is arranged on die shoe.
Guide frame is used for leading to upper bolster and die shoe, makes shaping more stable, improves product accuracy.In the production process of pump cover, plate is positioned on forming terrace die by operating personnel, and upper bolster presses down, sheet forming.Forming terrace die is provided with four identical projections, and female die for forming is provided with four identical grooves matched with described projection.In the process that upper bolster presses down, the extruding that plate is subject to described projection is channel form, and these four grooves are shaped simultaneously, reach the uniformity of production.This with utilize milling machine to compared with the mode of Sheet Metal Processing, improve the production efficiency of pump cover.The mode of production of pump cover changes into and utilizes mould to produce by the utility model, and improve production efficiency, accuracy is high, also improves product percent of pass, and then ensures product quality.The guide frame be made up of guide pin bushing and guide pillar, for leading to upper bolster and die shoe, allows pump cover be shaped more stable, improves product accuracy.When upper bolster presses down, guide pillar inserts in guide pin bushing, ensures that forming terrace die can completely contact with female die for forming, improves product percent of pass.
Owing to have employed technique scheme, the utility model has the simple advantage of structure, and it can improve production efficiency and the accuracy of pump cover, can also improve the product percent of pass of pump cover, and then ensures product quality.

Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As Figure 1-3, the utility model includes upper bolster 1 and die shoe 2, guide frame is provided with between described upper bolster 1 and described die shoe 2, upper bolster 1 is provided with shaping boss 3, shaping boss 3 is provided with female die for forming 4, die shoe 2 is provided with the forming terrace die 5 matched with described female die for forming 4, described forming terrace die 5 is provided with four identical projections 11, described female die for forming 4 is provided with four identical grooves 12 matched with described projection 11, after upper bolster 1 is involutory with die shoe 2, described female die for forming 4 and described forming terrace die 5 form the pump cover die cavity closed.
Guide frame is used for leading to upper bolster 1 and die shoe 2, makes shaping more stable, improves product accuracy.In the production process of pump cover, plate is positioned on forming terrace die 5 by operating personnel, and upper bolster 1 presses down, sheet forming.With four identical projections 11 on forming terrace die 5, and female die for forming 4 is with four identical grooves 12 matched with described projection.In the process that upper bolster 1 presses down, the extruding that plate is subject to described projection 11 is channel form, and these four grooves are shaped simultaneously, reach the uniformity of production.This with utilize milling machine to compared with the mode of Sheet Metal Processing, improve the production efficiency of pump cover.The mode of production of pump cover changes into and utilizes mould to produce by the utility model, and improve production efficiency, accuracy is high, also improves product percent of pass, and then ensures product quality.
As shown in Figure 1, 2, the guide pillar 7 that described guide frame comprises guide pin bushing 6 and matches with guide pin bushing 6, described guide pin bushing 6 is arranged on upper bolster 1, and described guide pillar 7 is arranged on die shoe 2.The guide frame be made up of guide pin bushing 6 and guide pillar 7, for leading to upper bolster 1 and die shoe 2, allows pump cover be shaped more stable, improves product accuracy.When upper bolster 1 presses down, guide pillar 7 inserts in guide pin bushing 6, ensures that forming terrace die 5 can completely contact with female die for forming 4, improves product percent of pass.Particularly, the guide pin bushing 6 in column type and guide pillar 7 can be used.Cylindrical structure is simple, is easy to be shaped, and is easy to manufacture.
As shown in Figure 1, described upper bolster 1 is provided with press-working spring 8, and press-working spring 8 has the effect of buffering.When upper bolster 1 and the 2-in-1 mould of die shoe, press-working spring 8 contacts with die shoe 2, and by the compression of press-working spring 8, upper bolster 1 and die shoe 2 intimately coordinate, and is beneficial to pump cover and is shaped.
As shown in Figure 2, described die shoe 2 is provided with two limited posts 10, described limited post 10 is arranged in diagonal angle.Limited post 10 is incorporated into the degree of depth of die shoe 2 for limiting upper bolster 1, it highly equals the distance between upper bolster 1 and involutory rear two die holders of die shoe 2.Its length needs lengthening 0.5 millimeter when designing, and adjusts when being convenient to group mould.Described limited post 10 is arranged in diagonal angle, pump cover is shaped safer.
As shown in Figure 1, described shaping boss 3 is fixed on upper bolster 1 by trip bolt 9.
These are only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing the utility model description and accompanying drawing content to do; directly or indirectly be used in the technical field that other are relevant, all in like manner within scope of patent protection of the present utility model.
