SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model aims to provide a mould for quickly cooling a profiling waterway of a product, which has the advantage of uniformly cooling grooves of the product.

In order to achieve the purpose, the utility model provides the following technical scheme:

a mold for rapid cooling of a profiling waterway of a product comprises a movable template and a cover plate, wherein a profiling groove for profiling the outline of a groove of the product is arranged on one side of the movable template, which is far away from a parting surface, and the profiling groove is arranged on the front back surface of the contact part of the movable template and the bottom surface of the groove of the product; the cover plate covers the notch part of the profile groove, and is provided with a water inlet for cooling water to enter the profile groove and a water outlet for the cooling water to flow out of the profile groove.

By adopting the technical scheme, the profile groove is arranged on the front back surface of the contact part of the movable template and the groove of the product, so that the profile groove is closest to the bottom surface of the groove of the product, and under the condition of ensuring the processing precision and the strength of the movable template, the cooling water is closest to the bottom surface of the groove of the product, thereby accelerating heat conduction, uniformly cooling the groove of the product, preventing the outer layer of the product from sinking and improving the forming precision. The profile of the groove of the product is followed in the profile of the groove of the product, and compared with the traditional straight-through cooling water channel and baffle cooling water channel, the cooling water channel of the profile groove is closer to the average distance of the product, has better cooling effect and more uniform cooling area, can effectively prevent the product from warping and deforming caused by uneven cooling, enables the cooling water to be as close to most of the surface of the groove bottom of the groove of the product as possible, increases the contact surface area, increases the heat exchange area, accelerates the heat exchange, and improves the cooling efficiency.

Further, the contour of the cover plate is similar to that of a product and is in interference fit with the groove side face of the profiling groove.

Adopt above-mentioned technical scheme, the apron is the same and interference fit with the shape of profile groove, make zero clearance between apron and the profile groove, avoid the apron on the one hand at the in-process of cooling because expend with heat and contract with cold and cause and the profile groove between not hard up, make the apron firmly fix in the profile groove, on the other hand guarantees that seamless between apron and the profile groove, avoids the cooling water in the profile groove to spill from the apron, avoids the cooling water to pollute the product, guarantees the leakproofness in cooling water route, guarantees the shaping effect of product.

Furthermore, a shoulder is fixedly arranged on the side surface of the groove of the contour groove, and one side of the cover plate, which is close to the bottom of the contour groove, abuts against the shoulder.

Adopt above-mentioned technical scheme, the circular bead provides spacingly for the interior profile modeling groove of packing into of apron, on the one hand, avoids because the apron loads into the narrowing down of the cooling water route that the distance in the profile modeling groove is too much and lead to, reduces the cooling effect, and on the other hand avoids because the apron loads into the leakproofness between the not enough apron that leads to and the profile modeling groove of distance in the profile modeling groove not enough, and the cooling water is revealed, pollutes the product.

Further, the water inlet is arranged at one end of the profile groove, and the water outlet is arranged at the other end of the profile groove.

By adopting the technical scheme, the distance between the water inlet and the water outlet is as far as possible, so that the cooling water flows through all the inner surfaces of the profiling grooves, the contact area of heat exchange is increased, and the cooling effect is improved.

Furthermore, the distance between the plane of the movable template contacting with the bottom surface of the product groove and the bottom surface of the profile groove is 10mm-15 mm.

By adopting the technical scheme, the distance of 10mm-15mm not only ensures the processing precision and the strength of the movable template, but also ensures that the profiling groove is as close as possible to the product, so that the product is cooled rapidly, and the higher precision of product molding is ensured.

Further, the cover plate is made of copper alloy.

By adopting the technical scheme, the copper alloy has heat conductivity, so that the heat of the die can be conducted to the low-temperature part from the high-temperature part (product) as soon as possible, the cooling is accelerated, and the cooling efficiency is improved.

Furthermore, one side of the cover plate, which is far away from the groove bottom of the profiling groove, and one side of the movable mould plate, which is far away from the parting surface, are positioned on the same plane.

By adopting the technical scheme, after the cover plate is arranged on the movable mould plate, one side of the movable mould plate, which is far away from the parting surface, is integrally formed into a flat surface, and the contact surface of the movable mould plate and the movable mould mounting plate is formed into a flat surface. If the cover plate is higher than the movable mould plate, the contact surface of the movable mould plate and the movable mould mounting plate is smaller, the movable mould plate is easy to shake on the movable mould mounting plate, the forming precision of a product is influenced, if the cover plate is lower than the movable mould plate, the profiling groove is easy to eject out of the cover plate by the water pressure when cooling water flows into the profiling groove, the cooling water is leaked, the product is polluted, and the forming precision of the product is influenced.

Furthermore, a water inlet and a water outlet of the cover plate are connected with a refrigerator through water pipes.

Adopt above-mentioned technical scheme, the refrigerator makes the cooling water cooling, and the cooling water after the cooling flows into the mould, for the product cooling, great difference in temperature improves cooling efficiency, and after mould and the heat conduction of cooling water, the mould temperature reduces, and cooling water temperature risees, and the cooling water flows into in the refrigerator, realizes the used cycle of cooling water.

In conclusion, the utility model has the following beneficial effects:

1. compared with the traditional straight-through cooling water channel and baffle cooling water channel, the water channel formed by the profile groove and the cover plate has the advantages of easier processing and low manufacturing cost;

2. the shoulder provides a limit for the cover plate when being arranged in the profiling groove, ensures the uniformity of a cooling water path in the die, ensures that all surfaces of the product are uniformly cooled, and ensures the uniformity of material tissues of the product;

3. the material of apron is the copper alloy, and the copper alloy has good heat conductivity, and the temperature with the product is leading-in microthermal position for the cooling of product.
