Problems solved by technology
[0003] The existing cooling channel preparation method is to use a drilling machine, and the formed cooling channel is linear. In this way, each cooling channel is distributed on the same level, and for plastic molds with complex shapes, it is impossible to achieve accurate mold accuracy by using this method. Uniform cooling of each point affects the quality of plastic parts and reduces production efficiency

Embodiment Construction
[0017] Such as figure 1 , figure 2 As shown, the plastic mold cooling device provided by the present invention includes a cavity 1, a core 2 and a cavity 3; in the cavity 1, the core 2, at least one cooling layer 4 is provided simultaneously or separately, and in the cooling layer 4 A cooling water channel 5 consistent with the shape of the mold cavity 3 is provided on the top, so that the distance from each layer of the cooling water channel 5 to the mold cavity 3 is equal. The area of each cooling layer 4 except the cooling water channel 5 is welded and sealed by welding, and the cooling water channels 5 of each layer are connected to each other and connected to the water inlet 6 and the water outlet 7 to form a passage.
[0018] The cooling water enters the plastic mold cooling device from the water inlet 6, and is diverted to the cooling water channel 5 in each cooling layer 3. After cooling down quickly and evenly, it is finally discharged from the water outlet 7.

The invention discloses a cooling gallery of a plastic forming die and a preparation method of the cooling gallery. Multilayered cooling galleries are arranged inside a plastic die cooling device to improve the cooling velocity, reduce the cooling time, and improve the output accordingly; a perpendicular distance from each cooling gallery on each cooling layer to a die cavity can be equal to enable the temperature everywhere of the die to be uniform, and the cooling velocity to be identical, so as to effectively prevent deformation of a plastic part, ensure the product quality, and improve the production efficiency. The cooling layers are connected in a welding manner to ensure that the sealing performance of the system under high pressure can be good. The cooling gallery of the plastic forming die produced by the machining method can sufficiently cool the piece; with adoption of the preparation method, the cooling galleries with complicated shapes is easy to machine.
Description
technical field [0001] The invention relates to a cooling water channel of a plastic forming mold and a preparation method thereof. Background technique [0002] With the continuous improvement of the quality of life and the development of the plastics industry, plastic products are used in various fields of life and production, and the requirements for the shape of plastic products are continuously improved. The degree of warpage change in the shape of plastic products has become one of the important criteria for judging the quality. One of the main factors restricting the shape change of plastic products is the cooling of plastic molds. Effective cooling can reduce cooling time, thereby increasing production; moreover, uniform cooling can reduce residual stress caused by uneven heat conduction, thereby controlling product warpage to maintain product dimensional accuracy and stability, thereby improving product quality the quality of. [0003] The existing cooling channe...
