Abstract
The invention discloses a front mold internal full-closed core-pulling mechanism which is characterized by mainly comprising a core shaft, a plurality of large-angle core-pulling blocks and a plurality of small-angle core-pulling blocks. The large-angle core-pulling blocks and the small-angle core-pulling blocks surround the core shaft at intervals, are connected with the core shaft in a sliding mode through dovetail grooves and can move up and down along the outer wall of the core shaft; the large-angle core-pulling blocks have the pulling angle of 20 degrees; and the small-angle core-pulling blocks have the pulling angle of 10 degrees. During mold opening, the core shaft is drawn downwards and drives the six surrounding core-pulling blocks to retract inwards. Because the pulling angle of the large-angle core-pulling blocks is different from that of the small-angle core-pulling blocks, the six core-pulling blocks have enough space after retraction and can not interfere with each other, a product can be easily free from a reverse-cover state to be demoulded smoothly, and the retraction and top opening are carried out in sequence.
Description
Technical field
The present invention relates to a kind of mould, particularly relate to a kind of front mold internal full-closed core-pulling mechanism.
Background technology
Present product structure design becomes increasingly complex, and the product that more all can not accomplish all designs now, forces the mould production technology to bring in constant renewal in, and constantly creates new construction and meets the production requirement.For example a kind of part 10 (as shown in Figure 1) with whole circle back-off 101, the method for side core-pulling is carried out the demoulding in adopting only.
Summary of the invention
The object of the present invention is to provide stable, the reliable front mold internal full-closed core-pulling mechanism of a kind of action.
For achieving the above object, technical solution of the present invention is:
The present invention is a kind of front mold internal full-closed core-pulling mechanism, and it mainly is made up of mandrel, polylith wide-angle piece and the polylith low-angle piece of loosing core of loosing core; Loose core piece and polylith low-angle of described polylith wide-angle loosed core the block gap around the periphery that is arranged in mandrel, and polylith wide-angle piece and the polylith low-angle piece of loosing core of loosing core slips by dovetail groove and mandrel, can move up and down along the outer wall of mandrel; The loose core withdrawing angle of piece of described wide-angle is 20 °, and the loose core withdrawing angle of piece of described low-angle is 10 °.
Described polylith wide-angle piece and the polylith low-angle piece of loosing core of loosing core is all three.
After adopting such scheme, the present invention mainly is made up of mandrel, polylith wide-angle piece and the polylith low-angle piece of loosing core of loosing core.The loose core withdrawing angle of piece of described wide-angle is 20 °, and the loose core withdrawing angle of piece of low-angle is 10 °.When die sinking, mandrel pulls down, drive in six pieces of loosing core of periphery and contract, the loose core withdrawing angle of piece of piece and low-angle is different because wide-angle is loosed core, after six pieces of loosing core shrink enough spaces are arranged, can not interfere between mutually, make product can be easy to break away from the back-off state, the smoothly demoulding, and shrink and back down in order successively.
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the axonometric drawing of product;
Fig. 2 is a vertical view of the present invention;
Fig. 3 is a cutaway view of the present invention;
Fig. 4 is the axonometric drawing of die sinking of the present invention;
Fig. 5 is the procedure chart of die sinking of the present invention.
The specific embodiment
As shown in Figure 2, the present invention is a kind of front mold internal full-closed core-pulling mechanism, and it mainly is made up of mandrel 1, three wide-angles piece 2 and the three low-angles piece 3 of loosing core of loosing core.
Loose core piece 2 and three low-angles of described three wide-angles are loosed core piece 3 spacer rings around the periphery that is arranged in mandrel 1, and three wide-angles piece 2 and three low-angles piece 3 of loosing core of loosing core slips by dovetail groove 11 and mandrel 1, can move along the outer wall of mandrel 1 is upper and lower; As shown in Figure 3, the loose core withdrawing angle of piece 2 of described wide-angle is 20 °, and the loose core withdrawing angle of piece 3 of described low-angle is 10 °.
Operation principle of the present invention:
As Fig. 4, shown in Figure 5, when die sinking, mandrel 1 pulls down, driving loose core piece 2 and three low-angles of three wide-angles looses core and contracts in the piece 3, the loose core withdrawing angle of piece 3 of piece 2 and low-angle is respectively 20 °, 10 ° (as shown in Figure 3) because wide-angle is loosed core, and withdrawing angle difference, three wide-angles piece 2 and the three low-angles piece 3 of loosing core of loosing core can not interfere between mutually when shrinking, make product 10 can be easy to break away from the back-off state, the demoulding smoothly.
Emphasis of the present invention just is: adopt the different piece of loosing core of withdrawing angle to carry out side core-pulling.
The above, only be preferred embodiment of the present invention, the quantity of the piece of loosing core can be different with angle, so can not limit scope of the invention process with this, the i.e. equivalence of doing according to the present patent application claim and description changes and modifies, and all should still belong in the scope that patent of the present invention contains.
Claims (2)
1. front mold internal full-closed core-pulling mechanism is characterized in that: it mainly is made up of mandrel, polylith wide-angle piece and the polylith low-angle piece of loosing core of loosing core; Loose core piece and polylith low-angle of described polylith wide-angle loosed core the block gap around the periphery that is arranged in mandrel, and polylith wide-angle piece and the polylith low-angle piece of loosing core of loosing core slips by dovetail groove and mandrel, can move up and down along the outer wall of mandrel; The loose core withdrawing angle of piece of described wide-angle is 20 °, and the loose core withdrawing angle of piece of described low-angle is 10 °.
