Description
Technical field
The invention belongs to Mold Making field, more particularly to cold explosion core mould manufacturing field, and in particular in a kind of explosion core mould
Loose piece auto resilient mounting.
Background technology
Mould is industrial underlying process equipment, is referred to as " mother of industry ", as the basic activity of national economy,
Mould is related to the industry-by-industries such as machinery, automobile, light industry, electronics, chemical industry, metallurgy, building, and application is quite varied.At present, I
The problems such as state achieves great development in field of mould production, but disparate development also be present, and product aggregate level is relatively low.
Explosion core mould is widely used in casting industry, has obvious advantage, and the core dimensional accuracy produced by it is high, surface quality
Good, explosion core mould cylinder iron makes more, has the characteristics that easy processing, easily casting, production efficiency are high, loose piece uses mould more in explosion core mould
Has the shaping of steel overall processing, because the upper mould of explosion core mould can not install loose piece, therefore appearance profile is done and caused greatly by part loose piece
Cost of manufacture wastes, and cost of manufacture is high；Complex operation, cumbersome in addition, loose piece is required for shutting down every time, installed, efficiency is low, greatly
Most loose pieces can only use dovetail key or magnet to position, and when playing type, loose piece and core are together taken out of, and loose piece is easy to fall off, cause
Damage.
In the patent document that notification number is CN206200017U, a kind of mould auto resilient mounting is disclosed, including it is upper
Material pressing core, lower material pressing core, locating dowel and active positioning block, the center at the top of the lower material pressing core are provided with boss, the upper pressure
Material core is located above boss, and the active positioning block is movably arranged on the inside of locating dowel, and one end of active positioning block is positioned at fixed
Outside the post of position, the end face is guiding surface, and guiding surface presses to boss towards boss, and by spring, and the bottom of active positioning block is set
There is clamping inclined-plane, the clamping inclined-plane is provided with two, be symmetrically fixed on convex with guiding surface by circular sliding slopes, the locating dowel
The both sides of platform, part from upper material pressing core press against to boss move when, part along guiding surface enter clamp inclined-plane, now two
Clamp inclined-plane and ensure that part does not shift in punching course, arc transition is used with guiding surface due to clamping inclined-plane,
Part is not in stuck phenomenon, device have it is simple in construction, be easily worked, convenient disassembly, positioning stablity, production efficiency height etc.
Advantage, still, the device are primarily adapted for use in diel field, for predominantly only one end has zero caused by positioning hole
The beam piece product of part position inaccurate on mould；One kind is disclosed in the patent document that notification number is CN201701289U
Mould core box takes out block structure, including upper die and lower die, and loose piece connecting rod, and loose piece is housed on loose piece connecting rod, and the two of loose piece connecting rod
