Abstract
The present invention relates to a kind of ejecting mechanisms applied to cover half, including model frame, lower roof plate and upper plate, cover half core is installed in model frame lower end, model frame upper center is provided with the chamber of indent, indoor four corners of chamber are vertically-mounted limited post, limited post is successively slidably fitted with upper plate and lower roof plate from top to bottom, it is fixed between upper plate and lower roof plate by screw, the upper end of limited post passes through upper plate and is cased with several spring leafs, the upper end opening of chamber is sealed by cover board, and mandril and release link are equipped in lower roof plate.The problem of present invention is designed by reasonable mould structure, is increased ejecting structure in cover half, is substantially improved in the process of die sinking because cavity structure complexity causes package power 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, and payload rate can reduce after general spring has received high temperature, and product just will appear unstable be good or bad.
Description
Technical field
The present invention 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
Technical problem to be solved by the invention is to provide a kind of ejecting mechanisms applied to cover half, pass through reasonable mold
Structure design increases ejecting structure in cover half, substantially improves in the process of die sinking because cavity structure complexity leads to package power mistake
Greatly, the problem of 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, generally
Spring received high temperature after payload rate can reduce, product just will appear unstable be good or bad.
The technical solution adopted by the present invention to solve the technical problems is: a kind of ejecting mechanism applied to cover half is provided,
Including model frame, lower roof plate and upper plate, cover half core is installed in the model frame lower end, model frame upper center setting
There is the chamber of indent, indoor four corners of the chamber are vertically-mounted limited post, and the limited post is from top to bottom successively
It is slidably fitted with upper plate and lower roof plate, is fixed between the upper plate and lower roof plate by screw, the limited post
Upper end passes through upper plate and is cased with several spring leafs, and the upper end opening of the chamber is sealed by cover board, the lower top
The mandril that several lower ends are inserted into cover half in-core is installed in plate, several lower ends are also equipped in the lower roof plate across cover half
The release link of core.
As a supplement to the technical solution of the present invention, the spring leaf is butterfly spring piece.
As a supplement to the technical solution of the present invention, the spring leaf uses the material of high temperature resistance and high strength
Material is made.
As a supplement to the technical solution of the present invention, four corners in the lower roof plate are vertical
Release link is installed.
The utility model has the advantages that designed the present invention relates to a kind of ejecting mechanism applied to cover half by reasonable mould structure,
Cover half increases ejecting structure, substantially improves in the process of die sinking because cavity structure complexity causes package power excessive, be easy to cause
Sticking to mould and the problem of deformation.In the process of die sinking, mandril acts preferentially on the position of mould product enclasping force increasing, auxiliary
Product stripping.And the spring leaf of high temperature resistance and high strength its stability is better than spring, and general spring effectively carries after having received high temperature
Lotus rate can reduce, and product just will appear unstable be good or bad.The method has the advantages that 1, prevent demoulding deformation,
2, product sticking to mould is prevented, 3, product qualification rate height greatly improve production efficiency.

Specific embodiment
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, those skilled in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Range.
Embodiments of the present invention are related to a kind of ejecting mechanism applied to cover half, as shown in Figs. 1-2, including model 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 indent
Chamber 9, four corners in the chamber 9 are vertically-mounted limited post 10, and the limited post 10 is from top to bottom successively
It is 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, the limit
The upper end of column 10 passes through upper plate 4 and is cased with several spring leafs 5, and the upper end opening of the chamber 9 is sealed by cover board 2,
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
A lower end passes 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 present invention passes through
Reasonable mould structure design increases ejecting structure in cover half, substantially improves in the process of die sinking because cavity structure complexity is led
The problem of cause package power is excessive, the sticking to mould be easy to causeing and deformation.In the process of die sinking, mandril 7 acts preferentially on mold production
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 spring, and one
As spring received high temperature after payload rate can reduce, product just will appear unstable be good or bad.
