Abstract
The invention provides a counter bore forming mold and aims at solving the problem that the connecting position of a counter bore hole and a clearing hole of a counter bore is easily disintegrated during demolding. The counter bore forming mold structurally comprises a fixed outer sleeve and a punching pin coaxially and movably arranged in the fixed outer sleeve and larger than the fixed outer sleeve in length, a radial cross section of the fixed outer sleeve is identical to a radial cross section of the counter bore hole of the counter bore, a radial cross section of the punching pin is the same as a radial cross section of the clearing hole of the counter bore, and an elastic resetting device is arranged right under the punching pin. During mold pressing, the punching pin presses the elastic resetting device, the periphery of the upper end of the punching pin is used as a clearing hole profile of the counter bore, the upper end face and the upper end periphery of the fixed outer sleeve serve as a counter bore hole profile of the counter bore, and the punching pin upward moves under the effect of the elastic resetting device during demolding. By utilizing even sliding contact of the punching pin, demolding of the clearing hole portion is first finished, then the fixed outer sleeve is demolded, demolding of the counter bore hole portion is finished, and the situation that the connecting position of the counter bore hole and the clearing hole is damaged by the mold.
Description
Technical field
The present invention relates to ceramic member manufacturing technology field, a kind of counterbore mould of specific design.
Background technology
Occurred in the market electric ceramic junction block, compared the junction block of conventional plastic, ceramic junction block has good insulating, and density is high, resistance to compression and intensity advantages of higher.But mostly existing ceramic junction block is by pug abrasive dust being added to soft paraffin and water stir slurry, the mould molding that reinjects, then calcining, in the process of calcining, remove paraffin, then the demoulding, then add quartz sand to fill up the hole of product blank, and then high temperature makes product porcelain.Such manufacturing process is quite loaded down with trivial details, produces bothersome and cost is high.And adopt the method for mould punching directly by the punch forming of mud powder, while there is product stripping again, be easy to the problem that the corner in hole is crumbled, particularly countersink region structure, in knockout course, often occurs when mould is extracted out destroy counter sink and pass through the situation of junction, hole.
Summary of the invention
The object of the invention is to propose a kind of counterbore mould, the counter sink of counterbore and the problem easily crumbling by junction, hole while solving the demoulding.
According to counterbore mould provided by the invention, key is to comprise fixed jacket cylinder and is coaxially movably arranged in described fixed jacket cylinder and length is greater than the red needle of fixed jacket cylinder, the radial cross-section of described fixed jacket cylinder is identical with the radial cross-section of the counter sink of counterbore, the radial cross-section of described red needle is identical with the radial cross-section that passes through hole of described counterbore, described red needle just below is provided with to elasticity reset device.
Counterbore mould of the present invention, in the time of pressing mold, red needle is to lower compression elasticity reset device, utilize red needle upper end periphery to pass through pass face as counterbore, utilize the upper surface of fixed jacket cylinder and the upper end periphery counter sink profile as counterbore, when the demoulding, red needle first moves up under the effect of elasticity reset device, utilize the even sliding-contact of red needle first to complete the demoulding by bore portion, again by the demoulding of fixed jacket cylinder, complete the demoulding of counter sink part, avoided mould destroy counter sink and pass through the situation of junction, hole.
Concrete, rounded or the square or polygon of the radial cross-section of described red needle, with adapt to various shapes counterbore pass through hole.
Concrete, rounded or the square or polygon of the radial cross-section of described fixed jacket cylinder, to adapt to the counter sink of counterbore of various shapes.
Further, described elasticity reset device is spring-supported gripper shoe, with simplified structure, reduces production costs.
Accompanying drawing explanation
Fig. 1 is the counter bore structure cutaway view that the present invention need to process.
Fig. 2 is structural representation of the present invention.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail as effect and the operation principle etc. of the mutual alignment between the shape of related each member, structure, each several part and annexation, each several part.
Embodiment 1:
As Fig. 1, counterbore mould of the present invention, comprise fixed jacket cylinder 1 and be coaxially movably arranged in fixed jacket cylinder 1 and length is greater than the red needle 2 of fixed jacket cylinder 1, the radial cross-section of fixed jacket cylinder 1 is identical with the radial cross-section of the counter sink of counterbore 3, the radial cross-section of red needle 2 is identical with the radial cross-section that passes through hole 4 of counterbore, red needle 2 just below is provided with to elasticity reset device 5.Wherein, the radial cross-section of red needle 2 is rounded, and the radial cross-section of fixed jacket cylinder 1 is rounded.Elasticity reset device 5 is spring-supported gripper shoe 5.When pressing mold, red needle 2 is to lower compression gripper shoe 5, utilize the profile of passing through hole 4 of red needle 2 upper end peripheries as counterbore, utilize the upper surface of fixed jacket cylinder 1 and the upper end periphery profile as the counter sink 3 of counterbore, when the demoulding, red needle 2 first moves up under the effect of gripper shoe 5, utilize the even sliding-contact of red needle 2 first to complete by the demoulding of hole 4 parts, again by 1 demoulding of fixed jacket cylinder, complete the demoulding of counter sink 3 parts, avoided mould destroy counter sink 3 and pass through the situation of 4 junctions, hole.
Claims (4)
1. a counterbore mould, it is characterized in that comprising fixed jacket cylinder and be coaxially movably arranged in described fixed jacket cylinder and length is greater than the red needle of fixed jacket cylinder, the radial cross-section of described fixed jacket cylinder is identical with the radial cross-section of the counter sink of counterbore, the radial cross-section of described red needle is identical with the radial cross-section that passes through hole of described counterbore, described red needle just below is provided with to elasticity reset device.
2. counterbore mould according to claim 1, is characterized in that rounded or the square or polygon of the radial cross-section of described red needle.
3. counterbore mould according to claim 1, is characterized in that rounded or the square or polygon of the radial cross-section of described fixed jacket cylinder.
