Abstract
The invention provides a mould core cooling structure. The mould core cooling structure is simple in structure and convenient to process while ensures a thimble and a waterway not to be interfered and comprises a front mould core, a back mould core, a flow channel and the thimble, wherein a cavity is formed between the front mould core and the back mould core, and the thimble penetrates through the back mould core and then is installed on the cavity in an ejecting mode. The mould core cooling structure is characterized in that a cooling cavity is arranged inside the back mould core and further extends to a part of B plate at the lower portion, a spiral water jacket is installed in the cooling cavity, the thimble penetrates through the center of the spiral water jacket, and the outer annular face of the spiral water jacket is provided with two parallel spiral channels. The tops of the two spiral channels are communicated, the bottom of one spiral channel is communicated with a water inlet pipe, the bottom of the other spiral channel is communicated with a water outlet pipe, a seal ring is arranged between contact faces of the spiral water jacket and the cooling cavity, and the spiral water jacket is specifically formed by processing yellow brass.
Description
Technical field
The present invention relates to the technical field of injection mould mould structure, be specially the 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 the 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 be canceled the existing complex structure that addresses this problem, processing difficulties.
Summary of the invention
For the problems referred to above, the invention provides the mold cores cooling structure, it guarantees thimble, hands-off while of water route, and is simple in structure, easy to process.
The 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 the cooling cavity, described cooling cavity also extends to the part B plate of bottom, in the 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 a described spiral fluted bottom is communicated with inlet pipeline, an other described spiral fluted bottom is communicated with 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 invention, because thimble runs through the center of spiral water jacket, 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 a described spiral fluted bottom is communicated with inlet pipeline, an other described spiral fluted bottom is communicated with 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 invention.
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 the 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 the 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, is provided with sealing ring 14 between the contact-making surface of spiral water jacket 8 and cooling cavity 6, and spiral water jacket 8 is specially brass and processes.Arrow is water (flow) direction among the figure.
