Abstract
The utility model provides a mould core cooling structure of a mould. The mould core cooling structure of the mould ensures that an ejector pin and a water passage do not interfere with each other and is simple in structure and convenient to machine at the same time. The mould core cooling structure of the mould comprises a front mould core, a back mould core, a flow passage and an ejector pin. A mould cavity is formed between the front mould core and the back mould core. After penetrating through the back mould core, the ejector pin is installed in the mould cavity in an abutted mode. The mould core cooling structure of the mould is characterized in that a cooling cavity body is arranged inside the back mould core. The cooling cavity body further extends to a B plate on the lower portion of the cooling cavity body. A spiral water jacket is installed in the cooling cavity body. The ejector pin penetrates through the center of the spiral water jacket. Two spiral grooves in parallel are formed in the outer annular surface of the spiral water jacket. The tops of the two spiral grooves are communicated mutually. The bottom portion of one of the spiral grooves is communicated with a water inlet pipeline, and the bottom portion of the other spiral groove is communicated with a water outlet pipeline. A sealing ring is arranged between the contact surface of the spiral water jacket and the contact surface of the cooling cavity body. The spiral water jacket is formed by machining brass concretely.
Description
Technical field
The utility model relates to the technical field of injection mould mould structure, is specially a kind of mold cores cooling structure.
Background technology
In order to shorten the cool time of goods, improve the quality of goods, to be provided with cooling water channel as much as possible on mould, particularly some large core parts, must lead to cooling water channel.But sometimes, just in time there is thimble the position that core will be travelled by water, and thimble can not cancel, the existing complex structure that addresses this problem, processing difficulties.
Summary of the invention
For the problems referred to above, the utility model provides a kind of mold cores cooling structure, and it guarantees thimble, hands-off while of water route, and is simple in structure, easy to process.
a kind of mold cores cooling structure, its technical scheme is such: it comprises the front mould core, the rear mold core, runner, thimble, described front mould core, form die cavity between the rear mold core, described thimble is mounted on described die cavity after running through described rear mold core, it is characterized in that: the inside of described rear mold core is provided with cooling cavity, described cooling cavity also extends to the part B plate of bottom, in described cooling cavity, spiral water jacket is installed, described thimble runs through the center of described spiral water jacket, the outer ring surface of described spiral water jacket is provided with the parallel helicla flute of twice, the described spiral fluted of twice top is connected, wherein be communicated with inlet pipeline bottom a described spiral fluted, an other described spiral fluted bottom connection outlet pipeline, be provided with sealing ring between the contact-making surface of described spiral water jacket and described cooling cavity, described spiral water jacket is specially brass and processes.
After adopting said structure of the present utility model, run through the center of spiral water jacket due to thimble, guarantee activity and the spiral water jacket mutually noninterfere of thimble, namely it guarantees that thimble, water route do not interfere; Because the outer ring surface of spiral water jacket is provided with the parallel helicla flute of twice, the described spiral fluted of twice top is connected, wherein be communicated with inlet pipeline bottom a described spiral fluted, an other described spiral fluted bottom connection outlet pipeline, be that cooling water is communicated to wherein helicla flute from inlet pipeline, and be circulated to the top along this helicla flute, then flow to the bottom along another helicla flute, then flow out from outlet pipeline, it is simple in structure, easy to process.
Description of drawings
Fig. 1 is front view structural representation of the present utility model.
The specific embodiment
see Fig. 1, it comprises front mould core 1, rear mold core 2, runner 3, thimble 4, front mould core 1, form die cavity 5 between rear mold core 2, thimble 4 is mounted on die cavity 5 after running through rear mold core 2, the inside of rear mold core 2 is provided with cooling cavity 6, cooling cavity 6 also extends to the part B plate 7 of bottom, in cooling cavity 6, spiral water jacket 8 is installed, thimble 4 runs through the center of spiral water jacket 8, the outer ring surface of spiral water jacket 8 is provided with the parallel helicla flute of twice 9, 10, twice helicla flute 9, 10 top 11 is connected, wherein the bottom of a helicla flute 9 is communicated with inlet pipeline 12, the bottom of an other helicla flute 10 is communicated with outlet pipeline 13, be provided with sealing ring 14 between the contact-making surface of spiral water jacket 8 and cooling cavity 6, spiral water jacket 8 is specially brass and processes.In figure, arrow is water (flow) direction.
