Abstract
The utility model relates to a cooling type core assembly comprising a mold core and a water sleeve, wherein the mold core is hollow, the water sleeve is arranged in the mold core, two spiral grooves are arranged on the outer surface of the water sleeve, two groove openings are oppositely arranged at the lower end of the water sleeve, and two through openings communicated with the two groove openings are correspondingly arranged on the mold core. The two groove openings are respectively communicated with one ends of the two spiral grooves. A backflow groove is arranged at the upper end of the water sleeve. The other end of each spiral groove is connected to the backflow groove, and the two spiral grooves are communicated with each other through the backflow groove. The cooling type core assembly shortens cooling time of an ejection molding element and improves work efficiency. Besides, the mold core and the water sleeve are simple in structure, easy to produce, low in manufacture cost and convenient to maintain.
Description
Technical field
The utility model relates to a kind of injection mold, and the cooling core assembly on especially a kind of injection mold belongs to the injection mold technical field.
Background technology
Add man-hour in injection moulding,, enhance productivity in order to shorten the cooling forming time of moulding; The people in the industry is aspect improvement injection mould cooling system; Made a lot of effort, be called " having the spiral fluted injection molding cooling core " like name, application number is 99814219.0 patent of invention; Cooling core on a kind of Coinjection molding apparatus is disclosed; This cooling core has the hollow elongated interior part that is positioned at the elongated exterior part of hollow, and top, all-in-one-piece garden shape drive end bearing bracket, the cooling fluid delivery chute that on the inner surface of the outer surface of inner part and exterior part, has the opposite helical direction respectively.This cooling core passes through through forcing the cooling fluid turbulent flow, has improved the cooling effectiveness of moulding.But the structure of this cooling core is very complicated, must make a pair of helicla flute with opposite helical direction at the outer surface of an inner part and the inner surface of an exterior part.This technological requirement of making for the helicla flute of exterior part inner surface is just quite high; And need be opposite with the helicla flute of inner part outer surface, corresponding; Increased the manufacturing cost of cooling core, for an injection mold, often needed a lot of cooling cores, this has just increased the difficulty of processing and the manufacturing cost of injection mold greatly; In case certain parts damages of cooling core, maintenance also are very big troubles.
The utility model content
The utility model purpose is that a kind of simple in structure, handling ease, cooling core easy to maintenance are provided for the deficiency that overcomes prior art.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of cooling core assembly comprises core and water jacket; The centre of said core is hollow; Said water jacket is positioned at core, and the outer surface of water jacket has two helicla flutes; The lower end of said water jacket is relative is provided with two notches, and also is provided with two ports that communicate with it on the core on the corresponding position; Said two notches communicate with two spiral fluted one ends respectively; The upper end of said water jacket also has a backflash; Said two spiral fluted other ends all are connected with backflash, and two helicla flutes are interconnected through backflash.
Preferably, said two spiral fluted hands of spiral are all identical with pitch.
Preferably, said spiral fluted cross section is U-shaped or semicircle.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
A kind of cooling core assembly of the utility model scheme is provided with water jacket in the inside that is positioned at core, and has two helicla flutes at the outer surface of water jacket; Two spiral fluted one ends communicate, and the other end communicates with port on the core through the notch on the water jacket respectively, and cooling fluid gets into from a port; Flow to the top through helicla flute, flow out from another port through another helicla flute again, do not stop around the cooling fluid that is flowing in the core; Shortened the cool time of moulding, improved production efficiency, and core and water jacket is simple in structure; Handling ease, low cost of manufacture, easy to maintenance.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is the structural representation of the utility model cooling core assembly;
Accompanying drawing 2 is the stereogram of the water jacket of the utility model cooling core assembly;
Accompanying drawing 3 is the front view of the water jacket of the utility model cooling core assembly;
Wherein: 1, core; 2, water jacket; 3, helicla flute; 4, notch; 5, port; 6, backflash.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Accompanying drawing 1-3 is the described a kind of cooling core assembly of the utility model, comprises core 1 and water jacket 2; The centre of said core 1 is hollow; Said water jacket 2 is positioned at core 1, and the outer surface of water jacket 2 has two helicla flutes 3; The hand of spiral of said two helicla flutes 3 is all identical with pitch, and the cross section of helicla flute 3 is a U-shaped; The lower end of said water jacket 2 is relative is provided with two notches 4, and also is provided with two ports that communicate with it 5 on the core 1 on the corresponding position; Said two notches 4 communicate with an end of two helicla flutes 3 respectively; The upper end of said water jacket 2 also has a backflash 6; The other end of said two helicla flutes 3 all is connected with backflash 6, and two helicla flutes 3 are interconnected through backflash 6.Cooling fluid gets into from one of them port 5 and notch 4, flows to the top through the helicla flute 3 that links to each other with this notch 4; Through backflash 6, flow in another helicla flute 3 again, flow out from another notch 4 and port 5.Do not stop to have shortened the cool time of moulding, improved production efficiency, and core and water jacket is simple in structure around the cooling fluid that is flowing in the core, handling ease, low cost of manufacture, easy to maintenance.
Like above-mentioned cooling core assembly, wherein the spiral fluted cross section can also be semicircle.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
