Abstract
The invention discloses a mold structure for a thin-piece product, which comprises a front mold plate, a rear mold plate, a front mold core and a rear mold core, wherein the front mold core and the rear mold core are respectively arranged in the front mold plate and the rear mold plate. A mold cavity identical to the thin-piece product to be molded in shape is formed between the front mold core and a rear mold model, one side of the mold cavity located on the front mold core is provided with a glue inlet opening, the other side of the mold cavity located on the rear mold core is provided with a slag discharging opening, and the glue inlet opening is of a bottle-opening-shaped structure with two symmetrical sides. The mold structure for the thin-piece product is not only simple in structure but also capable of enabling the product to be made thinner. In addition, defective phenomena of insufficient casting, bubbles, shrinkage cavities, air holes, cold insulation, film adhesion and the like are not prone to appear, so that yield is improved, and cost is reduced.
Description
Technical field
The present invention relates to a kind of thin part product and use mould structure.
Background technology
At present,, also there is following shortcoming for the moulding that approaches the part product in the die casting industry: the one, glue-feeder adopts asymmetric manner, causes the die erosion, is prone to phenomenons such as shrinkage cavity, mucous membrane, and the thick 0.8mm that can only accomplish of the minimum meat of product; The 2nd, deslagging is employed in the glue-feeder opposite side and only connects one or more square deslagging chambeies, and phenomenons such as casting, bubble, shrinkage cavity, pore and cold shut appear owing in this deslagging mode easily; The 3rd, the water route is provided with adopts two parallel water routes, and inhomogeneous cooling occurs distortion, crackle easily, owes casting, phenomenons such as bubble, cold shut and mucous membrane; The 4th, the product ejecting mechanism adopts a plurality of circular columns to eject, and area is very little, and product ejects and is, because contact area is little, pressure is big, occurs phenomenons such as product distortion, scratch, mucous membrane and shrinkage cavity easily.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of thin part product and use mould structure, this mould structure is not only simple; And can make thinner that product does; And be not prone to bad phenomenon such as owing casting, bubble, shrinkage cavity, pore, cold shut and mucous membrane, promote yield, reduce cost.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of thin part product is used mould structure; Comprise front template and rear pattern plate and be located at this front template respectively and rear pattern plate in front mould die and back mould die; Form and the consistent die cavity of thin part shape of product to be formed between said front mould die and the back mould model; And the side that this die cavity is positioned at front mould die and back mould die is provided with the glue-feeder opposite side and is provided with slag-drip opening, and said glue-feeder is the bottleneck shape structure of both sides symmetry.Like this, can make that product meat is thick to reduce to 0.6mm by original 0.8mm, practice thrift the die casting cost greatly, increase the range of application of extrusion process.
As further improvement of the present invention, said slag-drip opening connects an end of a corrugated deslagging cavity, and the wave of this deslagging cavity place direction is vertical with said slag-drip opening direction.
As further improvement of the present invention, the other end of said deslagging cavity communicates with ambient atmosphere.Like this, the pressure effect during the product charging can make gas residual in the cavity and waste material all empty, and reduces and owes phenomenons such as casting, bubble, shrinkage cavity, pore and cold shut, promotes yield.
As further improvement of the present invention, on the die of said back, be provided with square angled slide block.Like this, angled slide block can increase the contact area with product when ejecting product, reduces defectives such as product distortion, scratch, mucous membrane and shrinkage cavity.
As further improvement of the present invention, in said front mould die and back mould die, be respectively equipped with the water route, said water route comprises two parallel first water route and second water route and the 3rd water routes vertical respectively with this first and second water route one end and that be communicated with.Like this, can reduce distortion, crackle, owe phenomenons such as casting, bubble, mucous membrane and cold shut.
The invention has the beneficial effects as follows: adopt symmetrical bottleneck formula glue-feeder structure, can dwindle product and form thickness, the thick 0.6mm that reaches of minimum meat, thus practice thrift the die casting cost; Adopt waveform deslagging chamber and with the ambient atmosphere conducting, the pressure effect when making the product charging can make gas residual in the cavity and waste material all empty, phenomenons such as casting, bubble, shrinkage cavity, pore and cold shut are owed in minimizing, the lifting yield; Adopt three tunnel water route structures, can reduce distortion, crackle, owe casting, phenomenon such as bubble, mucous membrane and cold shut; Adopt block ejecting mechanism, angled slide block can increase the contact area with product when ejecting product, reduces defectives such as product distortion, scratch, mucous membrane and shrinkage cavity.

The specific embodiment
A kind of thin part product is used mould structure; Comprise front template 1 and rear pattern plate 2 and be located at this front template respectively with rear pattern plate in front mould die 3 and back mould die 4; Form and the consistent die cavity 5 of thin part product 10 shapes to be formed between said front mould die and the back mould model; And the side that this die cavity is positioned at front mould die and back mould die is provided with glue-feeder 6 opposite sides and is provided with slag-drip opening 7, and said glue-feeder is the bottleneck shape structure of both sides symmetry.Like this, can make that product meat is thick to reduce to 0.6mm by original 0.8mm, practice thrift the die casting cost greatly, increase the range of application of extrusion process.
Preferably, above-mentioned slag-drip opening connects an end of a corrugated deslagging cavity 8, and the wave of this deslagging cavity place direction is vertical with said slag-drip opening direction.
Preferably, the other end of above-mentioned deslagging cavity communicates with ambient atmosphere.Like this, the pressure effect during the product charging can make gas residual in the cavity and waste material all empty, and reduces and owes phenomenons such as casting, bubble, shrinkage cavity, pore and cold shut, promotes yield.
Preferably, on the die of above-mentioned back, be provided with square angled slide block 9.Like this, angled slide block can increase the contact area with product when ejecting product, reduces defectives such as product distortion, scratch, mucous membrane and shrinkage cavity.
Preferably, in above-mentioned front mould die and back mould die, be respectively equipped with the water route, said water route comprises two parallel first water route and second water route and the 3rd water routes vertical respectively with this first and second water route one end and that be communicated with.Like this, can reduce distortion, crackle, owe phenomenons such as casting, bubble, mucous membrane and cold shut.
