Abstract
The invention discloses a local cooling device for the interior of a plastic mold. The local cooling device comprises a water inlet pipe, a water outlet pipe, and an annular water guide pipe connected between the water inlet pipe and the water outlet pipe, wherein the annular water guide pipe is respectively communicated with a plurality of vertically arranged cooling branch pipes, and the cooling branch pipes are circumferentially and uniformly distributed on the annular water guide pipe; the upper and lower end parts of the cooling branch pipes are closed, and the side walls of the cooling branch pipes are provided with water inlets and water outlets; the water inlets and the water outlets are communicated with the annular water guide pipe, and a water insulation strip is arranged in each cooling branch pipe to divide the cooling branch pipe in half; the bottom of each water insulation strip is separated from the bottom end of the corresponding cooling branch pipe, and each water inlet and the corresponding water outlet are separated by the top of the corresponding water insulation strip; the top of each cooling branch pipe is provided with a jack matched with the corresponding water insulation strip, and the width of each water insulation strip is the same as the diameter of the corresponding cooling branch pipe; the top of each water insulation strip is provided with a limiting part, and the width of each limiting part is more than the diameter of the corresponding cooling branch pipe. A complicated part in the plastic mold can be cooled.
Description
Technical field
The present invention relates to a kind of cooling device, particularly the inner local cooling device of a kind of mould of plastics.
Background technology
Mould of plastics of the prior art, especially the mould of plastics that local is more complicated, uses the conventional type of cooling cannot realize it and cools completely, thus make the temperature difference of local temperature and mould other parts temperature larger, thus there is thermal deformation in the product of processing, affects the quality of whole converted products.
Summary of the invention
The object of the invention is to overcome the defect existed in prior art, provide a kind of mould of plastics inner local cooling device, can complicated local in cooling plastic mould.
For achieving the above object, technical scheme of the present invention there is provided the inner local cooling device of a kind of mould of plastics, comprise water inlet pipe and outlet pipe, be connected to the water guide endless tube between described water inlet pipe and described outlet pipe, described water guide endless tube is communicated with some vertically disposed cooling arms respectively, described cooling arm is uniformly distributed along the circumference of described water guide endless tube, the both ends up and down of described cooling arm are all closed, its sidewall offers water inlet and delivery port, described water inlet and described delivery port are connected with described water guide endless tube, the waterproof strip being divided into two halves is provided with in described cooling arm, the bottom of described waterproof strip and the bottom of described cooling arm are separated, described water inlet and described delivery port separate by its top, the top of described cooling arm offers the jack matched with described waterproof strip, the width of described waterproof strip is identical with the diameter of described cooling arm, its top has limiting section, the width of described limiting section is greater than the diameter of described cooling arm.
Further improvement: described water guide endless tube inner ring is provided with the first sealing ring, and its outer ring is provided with the second sealing ring.
Further improvement: described first sealing ring and described second sealing ring are all arranged in the draw-in groove that formed between described limiting section and described waterproof strip.
Advantage of the present invention and beneficial effect are: cooling water flows in water guide endless tube from water inlet pipe, then enter in first cooling arm, owing to being provided with waterproof strip, cooling water flows downward along the side of first cooling arm, due to follow-up hydraulic pressure after bottom arriving, and walk around waterproof strip and upwards enter next root cooling arm in flow starts back to water guide endless tube along the opposite side of cooling arm, the last outlet pipe that flows into again is discharged, cooling arm can insert part complicated in mould, cooling is convenient, and good cooling results.Water guide endless tube inner peripheral sealing ring is closed, and makes its internal cooling water circulation, does not drain to out die outside, and affects mould of plastics running.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is waterproof strip schematic diagram.
Wherein: 1, water inlet pipe; 2, outlet pipe; 3, water guide endless tube; 4, arm is cooled; 5, waterproof strip; 6, the first sealing ring; 7, the second sealing ring.
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1, the inner local cooling device of a kind of mould of plastics, comprise water inlet pipe 1 and outlet pipe 2, be connected to the water guide endless tube 3 between described water inlet pipe 1 and described outlet pipe 2, described water guide endless tube 3 is communicated with some vertically disposed cooling arms 4 respectively, described cooling arm 4 is uniformly distributed along the circumference of described water guide endless tube 3, the both ends up and down of described cooling arm 4 are all closed, its sidewall offers water inlet and delivery port, described water inlet and described delivery port are connected with described water guide endless tube 3, the waterproof strip 5 being divided into two halves is provided with in described cooling arm 4, the bottom of described waterproof strip 5 and the bottom of described cooling arm 4 are separated, described water inlet and described delivery port separate by its top, the top of described cooling arm 4 offers the jack matched with described waterproof strip 5, the width of described waterproof strip 5 is identical with the diameter of described cooling arm 4, its top has limiting section, the width of described limiting section is greater than the diameter of described cooling arm 4.
Operation principle illustrates: cooling water flows in water guide endless tube 3 from water inlet pipe 1, then enter in first cooling arm 4, owing to being provided with waterproof strip 5, cooling water flows downward along the side of first cooling arm 4, due to follow-up hydraulic pressure after bottom arriving, and walk around waterproof strip 5 and upwards enter next root cooling arm 4 in flow starts back to water guide endless tube 3 along the opposite side of cooling arm 4, finally flow into outlet pipe 2 again to discharge, circulate successively, because cooling arm 4 can stretch to the inside of labyrinth, then improve the cooling of labyrinth.
Overflow from the gap between waterproof strip 5 and cooling arm 4 to prevent cooling water, described water guide endless tube 3 inner ring is provided with the first sealing ring 6, and its outer ring is provided with the second sealing ring 7, makes its internal cooling water circulation, do not drain to out die outside, and affect mould of plastics running.
For the ease of the location of the first sealing ring 6 and the second sealing ring 7, described first sealing ring 6 and described second sealing ring 7 are all arranged in the draw-in groove that formed between described limiting section and described waterproof strip 5.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
