Description
Technical field
The present invention relates to mold design technical field, more particularly, to a kind of injection mold of uniform fast cooling.
Background technology
Mould be in industrial production to be molded, be blow molded, extrude, the method such as die casting or forging forming, smelting, punching press, stretching obtain the various moulds and instrument of required product.Injection mold injects fluid foods, it is cooled down again before die sinking afterwards first by dynamic model and cover half matched moulds in existing technology.Cooling procedure be the difference using the coefficient of thermal expansion and contraction of product and mould so that product separates with mould inner wall and allows product to be smoothly stripped after die sinking, the speed that cools down in this process and extremely important to the uniformity of each position of product cooling degree.The speed cooled down first can influence the length of stand-by period before molding, so as to affect indirectly the efficiency of production.In addition, in the case where being particular about speed, cooling after formed product is to allow product from temperature decrease more than its fusing point to the retainable temperature of conventional use of solid-state, therefore the uniformity of each position cooling degree of product influences whether the degree of the same time shrinkage of product so as to further influence the precision after formed product, and the uniformity cooled down also can produce influence to the cooldown rate of product on the whole.
The content of the invention
The main object of the present invention is that the speed and homogeneity question being directed to required by cooling procedure provide a kind of injection mold of uniform fast cooling.
In order to solve the above technical problems, the technical solution adopted by the present invention is a kind of injection mold of uniform fast cooling, including：Dynamic mould fixing plate, dynamic model, cover half, cover half fixed plate, the dynamic model is located at the lower end of dynamic mould fixing plate, the cover half is located at the upper end of cover half fixed plate, the lower end of dynamic model is provided with core rod, the upper end of cover half is provided with die cavity, the core rod and die cavity cooperatively form die cavity, the cooling chamber of " recessed " type rotary body shape is provided with around die cavity in the cover half, the material being located between die cavity and cooling chamber of cover half is copper, edge in the body of cover half close to its sidewall bottom is also embedded with refrigerator, air inlet and gas outlet are respectively equipped with the top of the opposite sides of the cooling chamber, admission line is provided between the air inlet and refrigerator, outlet pipe is provided between the gas outlet and refrigerator.
Further, the bottom of the side wall of the cover half is additionally provided with shift knob, and the shift knob is used for controlling the operating switch state and operating power of refrigerator.
Further, the refrigerant in the cooling chamber is nitrogen or ammonia.
The present invention has the advantages and positive effects of：The cooling chamber of " recessed " type rotary body shape surrounds die cavity, it is achieved thereby that in die cavity product each spot temperature rapid drawdown while property, cooling uniformity is more preferable；The material between die cavity and cooling chamber of being located at of cover half is set to copper, the characteristics of the heat conductivility for taking full advantage of copper in the case of preferable in view of the intensity of copper is high so that refrigerant in cooling chamber to the cooling of product faster；Air inlet and gas outlet set by the top of the opposite sides of the cooling chamber fully to be dispersed into any part of cooling chamber in cooling chamber by the refrigerant that refrigerator enters in cooling chamber and spray from the gas outlet of opposite side in side.Here refrigerant selects the nitrogen or ammonia of gaseous state shape, lightweight, and refrigerator is to refrigerant gas circulation temperature lowering, no waste gas discharge, good environmental protection；The shift knob not only can be for controlling the on off state of refrigerator but also can also adjust the operating power of refrigerator.
Reasonable in design of the present invention, integrated level is high, product can rapidly and uniformly be cooled before die sinking, so as to shorten the production time, improves the precision of shape of product.
Brief description of the drawings
Fig. 1 is the structural representation of the injection mold of the uniform fast cooling.
In figure：1- dynamic mould fixing plates, 2- dynamic models, 3- cover half, 4- cover half fixed plates, 5- core rods, 6- die cavities, 7- cooling chambers, 8- refrigerators, 9- admission lines, 10- outlet pipes, 10- shift knobs.
Embodiment
In order to be better understood from the present invention, the present invention is further described with reference to specific embodiments and the drawings.
As illustrated, the present invention provides a kind of injection mold of uniform fast cooling, including：Dynamic mould fixing plate 1, dynamic model 2, cover half 3, cover half fixed plate 4, the dynamic model 2 is located at the lower end of dynamic mould fixing plate 1, the cover half 3 is located at the upper end of cover half fixed plate 4, the lower end of dynamic model 2 is provided with core rod 5, the upper end of cover half 3 is provided with die cavity, the core rod 5 and die cavity cooperatively form the cooling chamber 7 that " recessed " type rotary body shape is provided with around the die cavity in die cavity 6, the cover half 3, so that cooling chamber 7 surrounds die cavity bottom and surrounding.The material being located between die cavity and cooling chamber of cover half is copper, edge in the body of cover half 3 close to its sidewall bottom is also embedded with refrigerator 8, air inlet and gas outlet are respectively equipped with the top of the opposite sides of the cooling chamber 7, admission line 9 is provided between the air inlet and refrigerator 8, outlet pipe 10 is provided between the gas outlet and refrigerator 8.
Specifically, the bottom of the side wall of the cover half 3 is additionally provided with shift knob 11, and the shift knob 11 is used for controlling the operating switch state and operating power of refrigerator 8.Refrigerant in the cooling chamber 7 is nitrogen or ammonia.
When the present invention is used, after injection fluid foods, rotary switch button 11 makes refrigerator 8 start working, and the operating power of refrigerator 8 can be increased by continuing rotary switch button 11, then refrigerant gas circulates to realize the cooling of the product to being enclosed in the die cavity in cooling chamber 7 by admission line 9, cooling chamber 7, outlet pipe 10.
