Abstract
A metal gravity casting die with an ejection mechanism comprises a metal gravity casting die body and the ejection mechanism. The ejection mechanism is composed of a mandril (8), a core ejection plate (9) and an ejection pushing block (10). Cavities in a fixed die (3) and a movable die (4) are barb-shaped cavities. An ejection pushing block access hole is arranged on the movable die (4), one end of the mandril (8) is arranged on a base of a movable die oil cylinder (6), the core ejection plate (9) is arranged at the other end of the mandril (8), the ejection pushing block (10) is connected with the core ejection plate (9) in rigid mode, and one end of the ejection pushing block (10) is provided with a barb-shaped groove matched with the barb-shaped cavities. The metal gravity casting die has the advantages that by means of a die sinking mechanism of a casting machine itself, different floating pushing block connecting mechanisms are designed, and self ejection of casting with a deep cavity structure or casting requiring a movable block to eject can be achieved. Compared with independent core pulling by using an oil cylinder traditionally, the structure is simplified, and cost is saved.
Description
Technical field
The utility model relates to the metal gravity casting die field, is specifically related to a kind of metal gravity casting die with ejecting mechanism.
Background technology
At present, how successfully foundry goods to be taken out from mould, be the important content of mould structure design and since the casting temperature that has just poured up to 400 ℃ about, low easily generation of intensity ejects distortion, traditional design is generally all used push rod, although simple in structure, when foundry goods has dark cavity configuration or needs many loose pieces somatotype, design is had higher requirement to mould ejection, this boosts productivity for guaranteeing product quality, and it is all significant to reduce cost.
The utility model content
The purpose of this utility model be exactly at present since the casting temperature that has just poured up to 400 ℃ about, low easily generation of intensity ejects distortion, traditional design is generally all used the deficiency of push rod, and a kind of metal gravity casting die with ejecting mechanism is provided.
The utility model comprises metal gravity casting die, metal gravity casting die is mainly by the leftover bits and pieces mould, base plate, cover half, dynamic model, casting machine installing plate and dynamic model oil cylinder form, base plate is installed on the leftover bits and pieces mould, cover half is installed on the leftover bits and pieces mould, and link to each other with base plate, cover half is provided with cup, have die cavity on the fixed half and moving half, the casting machine installing plate is installed in leftover bits and pieces mould top, dynamic model links to each other with casting machine installing plate bottom by the mould pin, the dynamic model oil cylinder is installed on the casting machine installing plate, it also has ejecting mechanism, ejecting mechanism is by push rod, plunger tip plate and eject pushing block and form, the die cavity in the fixed half and moving half is barb-like die cavity, has on the dynamic model and ejects the pushing block manhole appendix, on the base of push rod one end and dynamic model oil cylinder, the plunger tip plate is installed in the push rod other end, ejects pushing block and the plunger tip plate is rigidly connected, and ejects pushing block one end and has the barb-like groove that matches with barb-like die cavity.
The utility model has the advantages that: the die opening mechanism that utilizes casting machine self; by designing different unsteady injection block bindiny mechanism; can realize dark cavity configuration or need certainly ejecting of loose piece pushing out casting that loose core separately with former use oil cylinder and compare, namely simplified structure is saved again cost.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model comprises metal gravity casting die, metal gravity casting die is mainly by leftover bits and pieces mould 1, base plate 2, cover half 3, dynamic model 4, casting machine installing plate 5 and dynamic model oil cylinder 6 form, base plate 2 is installed on the leftover bits and pieces mould 1, cover half 3 is installed on the leftover bits and pieces mould 1, and link to each other with base plate 2, cover half 3 is provided with cup, have die cavity on cover half 3 and the dynamic model 4, casting machine installing plate 5 is installed in leftover bits and pieces mould 1 top, dynamic model 4 links to each other with casting machine installing plate 5 bottoms by the mould pin, dynamic model oil cylinder 6 is installed on the casting machine installing plate 5, and it also has ejecting mechanism, and ejecting mechanism is by push rod 8, plunger tip plate 9 and eject pushing block 10 and form, die cavity in cover half 3 and the dynamic model 4 is barb-like die cavity, have on the dynamic model 4 and eject the pushing block manhole appendix, on the base of push rod 8 one ends and dynamic model oil cylinder 6, plunger tip plate 9 is installed in push rod 8 other ends, eject pushing block 10 and be rigidly connected with plunger tip plate 9, eject pushing block 10 1 ends and have the barb-like groove that matches with barb-like die cavity.
Working method: solidify when finishing device reset and put to the cast starting bit, dynamic model 4 shifting formwork tool under the drive of dynamic model oil cylinder 6 is opened, because foundry goods 11(sees Fig. 1) and eject 10 of pushing blocks the overhead kick structure is arranged, under the effect of package power, foundry goods 11 and be connected with the plunger tip plate 9 that ejects pushing block 10 and on dynamic model 4, move, when on the plunger tip plate 9 that moves with after push rod 8 contacts, plunger tip plate 8, eject pushing block 10 and foundry goods 11 and move on stopping, at this moment eject pushing block 10 with foundry goods 11 with continue on the dynamic model 4 that moves separate, realized that foundry goods ejects.
