Description
Technical field
The present invention relates to a kind of rocket projectile jet pipe back segment compression molding forming mould, belong to the material forming technical field.
Background technology
Playing the arrow manufacture field, often needing the bigger jet pipe back segment compression moulding part of some draw ratios of processing, its structure is as shown in Figure 2, and the part of this shape uses widely in each serial product of rocket projectile.
At present, the home and abroad adds man-hour to the jet pipe back segment compression molding forming of rocket projectile, generally adopts the mode of center guide pillar structure compression tool processing.This center guide pillar structure compression tool is as shown in Figure 1, during compression moulding, in deciding with patrix centre pilot hole and counterdie center guide pillar, because of gapped between centre pilot hole and the counterdie center guide pillar, and with the Room of living together, material chamber.During work, patrix often because of plastics get between center guide pillar and the pilot hole, causes Qi Lagou even grinds dead phenomenon and often take place through the descending compression molding material of hydraulic press movable table, causes also difficulty of compression moulding demoulding difficulty, clear mould.The mode of this employing center guide pillar structure compression tool processing, labor strength is big, production efficiency is low, homogeneity of product is poor and the product precision does not often reach the specification requirement of design.
Summary of the invention
The objective of the invention is rocket projectile jet pipe back segment is carried out compression molding forming to add man-hour in order to solve existing center guide pillar structure compression tool; Can take place to cause Qi Lagou even grind dead phenomenon between plastics entering center guide pillar and the pilot hole; And a kind of rocket projectile jet pipe back segment compression molding forming mould is provided, in order to improve the product precision, reduce production costs; Enhance productivity, realize standardization, mass manufacturing.
The objective of the invention is to realize through following technical scheme:
A kind of rocket projectile jet pipe back segment compression molding forming mould of the present invention comprises: base, counterdie, bed die, external mold, stopping guide ring, patrix, cope match-plate pattern, interlock handle, interlock arm-tie, spacer pin.
Have external mold screens groove on the base; The external mold screens groove center of base is processed with stepped through hole; The stepped through hole of base is coaxial with external mold screens groove, and the last ladder internal diameter of the stepped through hole of base is less than the external diameter of design jet pipe back segment metal shell and greater than the internal diameter that designs jet pipe back segment metal shell;
Following mold cavity is stepped through hole, the sidewall epimere of counterdie for the front end internal thread place of design jet pipe back segment in the shape compression moulding working face that is complementary, the positioning table that the sidewall hypomere of counterdie is complementary for the stepped through hole with base;
The bed die hypomere is the boss that is complementary with counterdie downstairs hole, and the bed die epimere is the cover plate that is complementary with counterdie upper shoulder hole internal diameter;
The patrix sidewall is for removing the compression moulding working face that the interior shape of remainder is complementary behind the front end thread segment with design jet pipe back segment; The compression moulding working face front end of patrix is processed with the guide ledges that the upper shoulder hole with following mold cavity is complementary, and the guide ledges sidewall of patrix has deflector chute;
Outer mold cavity is processed with and designs the compression moulding working face that the profile of jet pipe back segment metal shell is complementary, and the external mold screens groove on outer die topography and the base is complementary, and the external mold sidewall upper is spacer pin fixedly;
Stopping guide ring center is processed with the guiding that is complementary with the patrix external diameter and passes through the hole, and stopping guide ring lower end is processed with the stopping boss that is complementary with outer mold cavity upper end, the fixing interlock of stopping guide ring sidewall handle;
Counterdie and external mold are placed on the base through screens platform structure respectively, and through screw external mold and base are fixed; The screens platform structure of bed die is placed in the stepped through hole of counterdie, and counterdie and bed die are located downwards through the positioning table structure respectively; The interlock arm-tie that has slotted hole is enclosed within simultaneously on the interlock handle of spacer pin and stopping guide ring of external mold; Patrix is connected with pressing equipment through cope match-plate pattern.
The course of work
Guiding through pressing equipment control patrix passes in the stopping guide ring is passed through the hole; The mould material is suppressed; The guiding of stopping guide ring plays guide effect to patrix simultaneously through the upper shoulder hole of hole and counterdie, and the deflector chute on the patrix guide ledges can make the mould material that flows into mold bottom in pressing process, flow out the cavity of bed die; Be enclosed within the interlock arm-tie of spacer pin and interlock handle simultaneously, the stopping boss that makes the stopping guide ring to the compression moulding workpiece to upper limit; Compacting is taken off the interlock arm-tie after accomplishing, and unloads the stopping guide ring through the interlock handle; Through hole through the base lower end is released mould simultaneously with spun work and counterdie, unloads counterdie at last, accomplishes depanning.
Beneficial effect
Mould structure of the present invention is simple, and is easy to process, thoroughly solved La Gou between guide pillar and the pilot hole, ground the key technology difficult problem that dead problem and product precision do not reach Design Requirement Drawing; Improve production efficiency, had very big application value.
