Abstract
The invention relates to an ejection mechanism of a fixed die push plate, which comprises a fixed die plate. Two corresponding installation grooves are arranged on the upper face and the lower face of the fixed die plate, an ejector pin retaining plate and a push plate are installed in the installation groove on the upper face of the fixed die plate from bottom to top, and three T-shaped installation holes are installed on the upper face of the push plate at equal intervals. A gasket and a plurality of belleville springs are padded on T-shaped shoulders of the installation holes from bottom to top, T-shaped guide bars are sleeved on the gasket and the belleville springs, and the lower portions of the heads of the guide bars protrude out to form small circular truncated cones which are in clearance fit with the T-shaped shoulders of the installation holes. The lower face of the push plate between every two installation holes abuts against an ejector pin. A fixed inner die is arranged in the installation groove on the lower face of the fixed die plate, release rods are installed on the left side and the right side of the fixed inner die, and the heads of the release rods abut against two sides of the lower face of the push plate. The ejection mechanism adopts the belleville springs to serve as pushing power producers, achieves fixed die auxiliary pushing functions during die sinking, and is ingenious in structure, even in pushing force distribution, and capable of improving force distribution quality of products.
Description
Technical field
The invention belongs to dieparts field, particularly relate to a kind of fixed mold push plate ejecting mechanism.
Background technology
In present mould production process, when die casting operation, product is easily stained with cover half, also deformation can be there is, and the deformation degree of national quality testing standard to product there are certain requirements, general provision deformation degree should lower than the deformation requirement of shaping processing, and the damaged products employed shaping machining to avoid the later stage and cause, makes product qualified rate reduce.In order to solve the problem, generally all on mould, ejecting mechanism is installed, but the complexity that existing ejecting mechanism structure all compares, and ejecting force skewness, easily cause snap gauge, thus do not reach the object of ejecting product, reduction deformation.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of fixed mold push plate ejecting mechanism, a cover half ejecting push plate mechanism is designed as requested when needing to eject to mould finished product, the elastic reaction that during matched moulds, disk spring produces after release link extruding, when die sinking, cover half push rod ejects product, makes to avoid being stained with mould and distortion during the die casting of mould finished product.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of fixed mold push plate ejecting mechanism, comprise solid plate, butterfly spring, pad, guide post, ejector pin retaining plate, push rod, determines internal mold, release link, push pedal, described solid plate above and below has the mounting groove of two correspondences, is provided with ejector pin retaining plate and push pedal from top to bottom above solid plate in mounting groove; Equidistantly have installing hole above push pedal, installing hole is T-shaped; On the T-shaped shoulder of installing hole, be lined with one piece of pad and some pieces of butterfly springs from top to bottom, on pad and butterfly spring, cover has guide post, guide post is T-shaped and centre has screwed hole, guide post head bottom surface and push pedal either flush, a little round platform is given prominence in guide post head bottom surface, the T-shaped shoulder matched in clearance of little round platform and installing hole; The diameter of guide post head is greater than installing hole, and the height of little round platform equals the amount of elastic deformation of disk spring, respectively withstands a push rod below installing hole push pedal between any two; Below solid plate, mounting groove is interior for determine internal mold, and determine the internal mold left and right sides and be provided with release link, the head of release link withstands both sides below push pedal.
Described installing hole has 2 at least.
Described pad diameter is greater than butterfly spring and the T-shaped shoulder matched in clearance of pad and installing hole.
Described guide post installs screw by screwed hole and solid plate is fixed.
Described push rod output contacts with product.
Beneficial effect
Structure of the present invention is ingenious, effectively can solve and be stained with cover half when die casting because of product and be out of shape the defective problem of mould finished product that causes.
Accompanying drawing explanation
Fig. 1 is disk spring combination installation diagram.
Fig. 2 is general assembly drawing of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
