Abstract
The utility model relates to a push plate ejection mechanism for a fixed die. The mechanism comprises a fixed template. Two corresponding mounting grooves are reserved on the upper and lower surfaces of the fixed template. A push rod fixing plate and a push plate are arranged from bottom to top in the mounting groove on the upper surface of the fixed template. Three T-shaped mounting holes are reserved at an equal interval in the push plate. A gasket and a plurality of Belleville springs are arranged from bottom to top on the T-shaped shoulder of each mounting hole. A T-shaped guide rod is sleeved on the gasket and the Belleville springs of each mounting hole. A small circular truncated cone is raised from the lower surface of the head part of each guide rod, and is in clearance fit with the T-shaped shoulder of the corresponding mounting hole. A push rod is pressed against the lower surface of the push plate between every two adjacent mounting holes. A fixed inner die is arranged in the mounting groove on the lower surface of the fixed template. Resetting rods are arranged on the left and right sides of the fixed inner die. The head parts of the resetting rods are pressed against the two sides of the lower surface of the push plate. The Belleville springs are used as ejection power sources, and have the function of assisting in the push-out of the fixed die during die opening; and the mechanism is ingenious in structure, and push-out force is uniformly distributed, so that the forming quality of a product can be improved.
Description
Technical field
The utility model belongs to the mould fitting field, particularly relates to a kind of cover half push pedal ejecting mechanism.
Background technology
In the present die production process; When die casting was operated, product was stained with cover half easily, also deformation can take place; And national quality testing standard has certain requirement to the deformation degree of product; General provision deformation degree should be lower than the deformation requirement of shaping processing, employs the damaged products that shaping processing is caused to avoid the later stage, makes product qualified rate reduce.In order to address the above problem, ejecting mechanism generally all is installed on mould, but the complicacy that existing ejecting mechanism structure all compares, and the ejecting force skewness, cause snap gauge easily, thereby do not reach the purpose that ejects product, reduces deformation.
The utility model content
The utility model technical problem to be solved provides a kind of cover half push pedal ejecting mechanism; Design a cover half push pedal ejecting mechanism in the time of need ejecting the mould finished product as requested; The elastic reaction that disk spring produces after the release link extruding during matched moulds; The cover half push rod ejects product when die sinking, avoids being stained with mould and distortion when making the die casting of mould finished product.
The utility model solves the technical scheme that its technical problem adopted: a kind of cover half push pedal ejecting mechanism is provided, comprises solid plate, butterfly spring; Pad, guide post, ejector pin retaining plate; Push rod is decided internal mold, release link; Push pedal, described solid plate above and below have the mounting groove of two correspondences, and ejector pin retaining plate and push pedal are installed in the mounting groove above the solid plate from top to bottom; Equidistance has installing hole above the push pedal, and installing hole is the T type; On the T of installing hole type shoulder; Be lined with one piece of pad and some pieces of butterfly springs from top to bottom; Be with guide post on pad and the butterfly spring, guide post is that T type and centre have screwed hole, and guide post head a end face is with to decide the internal mold end face concordant; A little round platform is given prominence in guide post head a bottom surface, the T type shoulder matched in clearance of little round platform and installing hole; Respectively withstand a push rod below the installing hole push pedal between any two; Below the solid plate in the mounting groove for to decide internal mold, decides the internal mold left and right sides release link is installed, the head of release link withstands both sides below the push pedal.
Described installing hole has 2 at least.
Described pad diameter is greater than the T type shoulder matched in clearance of butterfly spring and pad and installing hole.
Described guide post through screwed hole screw is installed and solid plate is fixed.
Described push rod output contacts with product.
Beneficial effect
The utility model structure is ingenious, can effectively solve when die casting to be stained with cover half and to be out of shape the defective problem of mould finished product that causes because of product.
Description of drawings
Fig. 1 is disk spring combine and assemble figure.
Fig. 2 is the utility model general assembly drawing.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
Like Fig. 1, a kind of cover half push pedal ejecting mechanism shown in Figure 2, comprise solid plate 1, butterfly spring 2; Pad 3, guide post 4, ejector pin retaining plate 5; Push rod 6 is decided internal mold 7, release link 8; Push pedal 9, described solid plate 1 above and below have the mounting groove of two correspondences, and ejector pin retaining plate 5 and push pedal 9 are installed in the mounting groove above the solid plate 1 from top to bottom; Equidistance has installing hole above the push pedal 9, and installing hole is the T type; On the T of installing hole type shoulder; Be lined with one piece of pad 3 and some pieces of butterfly springs 2 from top to bottom; Be with guide post 4 on pad 3 and the butterfly spring 2, guide post 4 is for T type and centre have screwed hole, and guide post head 4a end face is with to decide internal mold 7 end faces concordant; A little round platform is given prominence in guide post head 4a bottom surface, the T type shoulder matched in clearance of little round platform and installing hole; Respectively withstand a push rod 6 below the installing hole push pedal 9 between any two; Mounting groove is interior below the solid plate 1 decides internal mold 7 left and right sides release link 8 is installed for to decide internal mold 7, and the head of release link 8 withstands push pedal 9 following both sides.
Described installing hole has 2 at least.
Described pad 3 diameters are takeed on matched in clearance greater than butterfly spring 2 and pad 3 with the T type of installing hole, and the material hardness of pad 3 will be about HRC40.
Described guide post 4 through screwed hole screw is installed and solid plate 1 is fixing.
Described push rod 6 outputs contact with product.
During matched moulds, release link 8 extruding disk springs 2, and the height of little round platform is the amount of elastic deformation of disk spring 2, when moving, when cover half separates, disk spring 2 restores, and promotes push rod 6 simultaneously product is ejected.
