Description
Technical field
The utility model provides a kind of footwear mould structure, and the footwear mould of the injection molding manufacture procedure that refers to especially to be used to blow is constructed.
Background technology
Commonly use ejection formation and make shoes, must prepare mould, and mould forms with the upper die and lower die matched moulds all generally, so when finishing the shoes finished product, by the branch mould of patrix and counterdie, can take out the shoes finished product easily; The moulding shoes position of mould is set as die cavity, the foamed plastic liquation perfusion of die cavity feed flow attitude.
The ejection shaping die of commonly using, in the ejection formation process, the liquid foamed plastic liquation that mainly will melt, continue to be injected in the die cavity of mould, but because the foamed plastic liquation that pours into to the die cavity has touched the die cavity inwall in advance, and have influence on plastic melts begins to cool down and sticks together because inner wall temperature is lower, and on the other hand, the plastic melts that is introduced into also can begin the foaming, when the foaming plastic melts occupied the die cavity space, follow-up plastic melts can't continue to pour into again, so having many situations takes place, the one situation is exactly that the perfusion of plastic melts is certain inadequately, causes plastic melts material deficiency, so will produce moulding shoes fully, cause defective products to take place, its two situation is exactly the inner undue foaming of shoes, and causes the slot in its footwear to increase, and the shoes inner materials is too bulk, the packing deficiency, its three situation is sticked together the die cavity inwall for the shoes forming process, makes shoes rough surface after the moulding and not attractive in appearance, or moulding is incomplete.
Therefore, at the existing problem points of above-mentioned conventional construction, how to develop a kind of innovation structure that has more desirable practicality, the ardent hope of real consumer institute also is that relevant dealer must make great efforts target and the direction that research and development break through.
In view of this, the creator this in manufacturing development and the design experiences of being engaged in Related product for many years, at above-mentioned target, in detail after design and the scrupulous assessment, eventually the utility model of a true tool practicality.
Summary of the invention
The utility model purpose is, a kind of footwear mould structure of the injection molding manufacture procedure that is used to blow is provided, and to overcome the above-mentioned defective of known ejection formation footwear mould, the product yield promoted.
The technical characterstic of dealing with problems: a kind of footwear mould structure of the injection molding manufacture procedure that is used to blow, it is characterized in that, comprising:
One seat of honour, this seat of honour is combined with top cover by patrix and constitutes, top cover has material feeding groove, first feeding pipe, this material feeding groove is connected with first feeding pipe, and top cover has tracheae, and this patrix end face has the air flue that gas flow and sequence are worn, each air flue is connected with gas flow, patrix also has second feeding pipe, and it aligns with first feeding pipe that is connected top cover, and the patrix bottom surface has and footwear type corresponding protuberance in surface and recessed rank;
A seat, this following comprises a counterdie, counterdie has and the corresponding recess of footwear type basal surface, this footwear type basal surface recess periphery has the ring protuberance, ring protuberance neighboring has the circular groove groove, have some short slots on the ring protuberance, have the several through holes that are communicated to connectivity slot position, counterdie bottom surface on the circular groove groove of counterdie, and the circular groove groove has blast pipe horizontal and that pass to counterdie side steam vent.
Wherein, this patrix towards the patrix end face of top cover direction have around and the gas flow that traverses.
Wherein, this top cover has open material feeding groove.
Wherein, the gas flow periphery of this patrix has the leakproof cushion rubber.
Wherein, this patrix has the air flue that sequence is worn, and each air flue has the horizontal link slot that is connected to gas flow.
Wherein, this following comprises that also one is incorporated into the coldplate of counterdie bottom surface.
Wherein, this coldplate pastes mutually with counterdie and locking mutually, and coldplate inside is furnished with runner, and the coldplate outside has cooling water communicating pipe.
Wherein, this seat of honour end face pressing has a pressing mold that the material feeding groove is sealed, and pressing mold has involutory gas injection port in the top cover tracheae.
The effect of contrast prior art:
One, prior art is in filling process, promptly produce and pour into the problem of foaming earlier earlier, and the utility model produces suitable pressure in die cavity, pressure relief just after all raw materials pour into, so be that all raw materials foam simultaneously, yield hangs down improvement habit formula and the problem of foam overblow because supplied materials priority gap causes producing.
Two, in the filling process of prior art, can't avoid its foamed plastic liquation to be bound to contact with the die cavity inwall, and then glutinous situation is stained with in generation, so finished surface is quite coarse, or molding surface lines is incomplete, and pressed gas of the present utility model can be isolated plastic melts and contacted with the die cavity inwall, treats that perfusion is finished after release of pressure just allows the plastic melts foaming, so shoes finished product moulding rear surface is smooth, and molding surface lines is quite complete.
The technology that relevant the utility model adopted, means and effect thereof after lifting a preferred embodiment now and cooperating graphic being described in more detail in, are believed the above-mentioned purpose of the utility model, structure and feature, when can by one deeply and concrete understanding.
