Description
Technical field
The utility model relates to technical field of mold, more particularly to a kind of ejecting mechanism applied to cover half.
Background technique
Present die casting is higher and higher for size requirement, and deformation of products, size is unstable, leads to product qualification rate
Low production cost improves.In the process of die sinking, because cavity structure complexity causes package power excessive, sticking to mould and change are be easy to cause
Shape.And general, current mold is arranged ejecting mechanism on dynamic model, is easy to cause cover half that sticking to mould and deformation occurs.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of ejecting mechanisms applied to cover half, by reasonable
Mould structure design increases ejecting structure in cover half, substantially improves in the process of die sinking because cavity structure complexity causes to pack tightly
The problem of power is excessive, the sticking to mould be easy to causeing and deformation.And the spring leaf of high temperature resistance and high strength its stability is better than spring,
Payload rate can reduce after general spring has received high temperature, and product just will appear unstable be good or bad.
The technical scheme adopted by the utility model to solve the technical problem is as follows: providing a kind of ejector applied to cover half
Structure, including model frame, lower roof plate and upper plate are equipped with cover half core in the model frame lower end, the model frame upper center
It is provided with the chamber of indent, indoor four corners of the chamber are vertically-mounted limited post, and the limited post is from top to bottom
It is successively slidably fitted with upper plate and lower roof plate, is fixed between the upper plate and lower roof plate by screw, the limit
The upper end of column passes through upper plate and is cased with several spring leafs, and the upper end opening of the chamber is sealed by cover board, described
The mandril that several lower ends are inserted into cover half in-core is installed in lower roof plate, several lower ends is also equipped in the lower roof plate and passes through
The release link of cover half core.
As a kind of supplement to technical solution described in the utility model, the spring leaf is butterfly spring piece.
As a kind of supplement to technical solution described in the utility model, the spring leaf uses high temperature resistance and high strength
Material be made.
As a kind of supplement to technical solution described in the utility model, four corners in the lower roof plate are equal
It is vertically-mounted to have release link.
The utility model has the advantages that being set the utility model relates to a kind of ejecting mechanism applied to cover half by reasonable mould structure
Meter increases ejecting structure in cover half, substantially improves in the process of die sinking because cavity structure complexity causes package power excessive, be easy
Caused by sticking to mould and deformation the problem of.In the process of die sinking, mandril acts preferentially on the position of mould product enclasping force increasing,
Assist product stripping.And the spring leaf of high temperature resistance and high strength its stability is better than spring, and general spring has after having received high temperature
Effect loading rate can reduce, and product just will appear unstable be good or bad.The utility model has several advantages that 1, anti-anti-avulsion
Moding shape, 2, prevent product sticking to mould, 3, product qualification rate it is high, greatly improve production efficiency.
Detailed description of the invention

Fig. 2 is the schematic diagram that the utility model is splitted.
Diagram: 1, model frame, 2, cover board, 3, lower roof plate, 4, upper plate, 5, spring leaf, 6, release link, 7, mandril, 8, fixed
Mold core, 9, chamber, 10, limited post.
Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
The embodiments of the present invention is related to a kind of ejecting mechanism applied to cover half, as shown in Figs. 1-2, including cover half
Frame 1, lower roof plate 3 and upper plate 4 are equipped with cover half core 8 in 1 lower end of model frame, which is provided with
The chamber 9 of indent, four corners in the chamber 9 are vertically-mounted limited post 10, and the limited post 10 is from top to bottom
It is successively slidably fitted with upper plate 4 and lower roof plate 3, is fixed between the upper plate 4 and lower roof plate 3 by screw, it is described
The upper end of limited post 10 passes through upper plate 4 and is cased with several spring leafs 5, and the upper end opening of the chamber 9 passes through 2 envelope of cover board
Firmly, the mandril 7 that several lower ends are inserted into cover half core 8 is installed in the lower roof plate 3, is also equipped in the lower roof plate 3
Several lower ends pass through the release link 6 of cover half core 8.
The spring leaf 5 is butterfly spring piece.
The spring leaf 5 is made of the material of high temperature resistance and high strength.
Four corners in the lower roof plate 3 are vertically-mounted release link 6.
Embodiment
When mold clamping, by die casting machine clamp force, lower mould (i.e. dynamic model) pushes release link 3 to move upwards, and resets
The linkage upper plate 4 of bar 3 and lower roof plate are upward together, so that spring leaf 5 compresses, molding is completed, and spring leaf 5 is in forced compression shape
State.Die casting movement starts to carry out filling die casting, and when die casting terminates, mold die sinking is sprung back while spring leaf 5 is with die sinking, by
The promotion of 5 screen resilience of spring leaf, mandril 7 is synchronous to eject cover half for product, and the cover half for completing product smoothly demoulds.The utility model
It is designed by reasonable mould structure, increases ejecting structure in cover half, substantially improved in the process of die sinking because cavity structure is multiple
It is miscellaneous to cause package power excessive, the problem of the sticking to mould be easy to causeing and deformation.In the process of die sinking, mandril 7 acts preferentially on mould
Have the position that product enclasping force increases, assists product stripping.And the spring leaf 5 of high temperature resistance and high strength its stability is better than bullet
Spring, payload rate can reduce after general spring has received high temperature, and product just will appear unstable be good or bad.
