The method realizes the processing of the appearance of an article mainly by changing the physical state of a formed material, and makes a blank become a tool of a workpiece with a specific shape and size under the action of external force, and is widely used for blanking, die forging, cold heading, extrusion, powder metallurgy part pressing and pressure casting, and the forming processing of compression molding or injection molding of products such as engineering plastics, rubber, ceramics and the like.
At present, most of single molds on the market can only manufacture single products, and the mold cores of different products cannot be replaced, so that the production of various products of different types cannot be carried out on the single mold, and the investment cost of the mold is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving and having the mold core that can't change different kind products among the prior art for can't carry out the production of multiple different grade type product on single mould, increased shortcomings such as the input cost of mould, and the mould of the bilayer core structure that contracts in proposing.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a mould of double-deck core structure contracts in design, the on-line screen storage device comprises a base, the fluting has been seted up to the one end of base, the inner of fluting is provided with draws and rises the piece, draw rise the piece with elastic connection has the spring that draws between the fluting, the one end that draws the piece is provided with the fixed slot, the one end setting of base with fixed slot grafting complex fixed block, the one end of fixed block is provided with fixing spring, fixing spring's one end fixed connection in the base, the one end that draws the piece is provided with multiunit fixing device, fixing device's upper end fixedly connected with mould body.
Preferably, the fixing device comprises a fixing rod, an L-shaped groove is formed in one end of the pulling block, the fixing rod is matched with the L-shaped groove in an inserting mode, a connecting groove is formed in one end of the fixing rod, a connecting block is arranged at the inner end of the connecting groove, a connecting spring is elastically connected between the connecting block and the connecting groove, and the connecting block is matched with the L-shaped groove in an inserting mode.
Preferably, one end of the connecting block is provided with a pulling block, and the pulling block is connected with the connecting groove in a sliding mode.
Preferably, the connecting block is a wedge-shaped block.
The utility model provides a mould of double-deck core structure contracts in, beneficial effect lies in: extract the fixed block earlier, so alright will draw the piece through the spring and pop out, the piece is drawn in the rethread pulling, drives the connecting rod through drawing the piece, makes in the connecting rod slips into the spread groove, so alright take off the mould body from drawing the piece, so alright change with to the mould body.
