Description
[technical field]
The cast gate of the relevant a kind of mould of the utility model slide block type cast gate, particularly relevant a kind of slide block type cast gate that is applied to the mold goods.
[background technology]
Cast gate is a most important component in the mould structure, it is directly determining the quality of the product of institute's moulding, the selection of gate location also is important in addition, and therefore, the different of the type of cast gate and the position of cast gate all will produce bigger influence to the quality and the outward appearance of product.The existing mold goods generally all are provided with mating surface, and mating surface is above be appearance, and outward appearance processing requirements appearance is minute surface, just require cannot have on the appearance into glue point, as if advancing glue at mating surface, then require the cast gate defective material can not protrude the mating surface surface.General it advances the glue mode generally can adopt sub marine gate (cattle horn shape) for the mold goods with this specific character, adopts sub marine gate to advance the glue mode and has the following disadvantages:
The one, that adopts sub marine gate advances the glue mode, the Mould Machining more complicated that makes, and the mould design is difficult for, and die manufacturing cost increases, thus the production cost of the goods that make improves greatly, and the production efficiency that makes, benefit reduce.
The 2nd, that adopts sub marine gate advances the glue mode, and after breaking at cast gate, the residual salient point in gate location place need be done at mating surface wall thickness place and empty processing, and the residue waste material that makes like this is many, thereby has increased production cost, reduces productivity effect.
The 3rd, that adopts sub marine gate advances the glue mode, and in forming process, the pressure loss is bigger, the lost of life of the mould that makes, and product is long cool time in this process, and the life cycle of the product that makes is long, thereby has reduced production efficiency of products.
The 4th, that adopts sub marine gate advances the glue mode, because product wall thickness problem can produce the shade shrink mark on the surface of product, the appearance of the product that makes does not reach the requirement of use, and the surface quality of products that makes reduces greatly.
In view of this, in fact be necessary to propose a kind of surface quality that helps improving die products, and be suitable for using high efficiencyly advance the glue cast gate.
[summary of the invention]
The purpose of this utility model is exactly a kind of slide block type cast gate that is suitable for using that proposes in order to address the above problem.The utility model slide block type cast gate can provide a kind of mould design easily, and Mould Machining is simple, and charging rate is fast, and product is short cool time, and with short production cycle, the pressure loss is little, and the slide block type cast gate that is suitable for using.
This slide block type cast gate is applied to a mould, this mould is provided with a master mold, the opposite of this master mold is provided with a male model, this male model is provided with and is no less than a die cavity, the side of this die cavity is provided with and is no less than a flow path groove, this flow path groove one end is provided with a gate orifice, this gate orifice links to each other with corresponding die cavity, this is provided with slide block slot above flow path groove, be provided with a slide block in this slide block slot, and this slip front is provided with the part of die cavity, the bottom of this part communicates with gate orifice, after this slide block enters slide block slot, the bottom surface of this slide block, the notch of side and flow path groove is adjacent to, and forms complete material body passage, the part die cavity of the front end of this slide block and the part die cavity on the male model match, form complete die cavity, the bottom of this part die cavity and the gate orifice of flow path groove match, and form complete glue-feeder.
It is that mainly it adopts new structure, can produce following advantage the utility model slide block type cast gate:
The one, what the utility model slide block type cast gate adopted this kind structure advances the glue mode, and the mould that makes design is than being easier to, and Mould Machining is fairly simple, and die manufacturing cost reduces, thereby the production cost of products that makes reduces, the productivity effect rising.
The 2nd, what the utility model slide block type cast gate adopted this kind structure advances the glue mode, make it have big inlet amount, the formation of internal stress and the chance that buckling deformation takes place have been reduced, and it has higher shear rate, break the difficult salient point that forms in the process at cast gate, thereby reduced remaining waste material, reduced production cost of products.
The 3rd, what the utility model slide block type cast gate adopted this kind structure advances the glue mode, in forming process, has reduced cavity pressure, reduces clamp force, has prolonged the life-span of mould, and the pressure loss in this process that also makes reduces.
The 4th, what the utility model slide block type cast gate adopted this kind structure advances the glue mode, appearance is not advanced the glue point, inlet amount is bigger, the pressure loss is smaller, the product cooling raio that makes is very fast, and the production cycle is shorter, and product is difficult for shrinking, therefore product surface is difficult for forming the shade shrink mark, has improved the surface quality of goods greatly.
What the utility model slide block type cast gate adopted this kind structure advances the glue mode, and the applied mould structure that makes is simple, easy to manufacture, helps adopting the applying of mould of the utility model slide block type cast gate like this.
