Description

Technical Field

[0001] The utility model relates to the technical field of rotational molding technology, in particular to a mold cooling device for the production of rotational molding raw materials. Background Art

[0002] The basic principle of rotational molding is to place powdered plastic raw materials into a mold, which is then continuously rotated along two vertical axes and heated. Under the action of gravity and thermal energy, the plastic raw materials in the mold are gradually and evenly coated, melted and adhered to the entire surface of the mold cavity to form the desired shape. After that, the mold enters the cooling stage and is cooled by forced ventilation or water spraying to solidify the product.

[0003] In the existing technology, the problem with using air cooling for cooling is: the heat transfer efficiency is low, so it usually takes a long cooling time for the product to reach the required temperature, which may extend the entire production cycle and reduce production efficiency; the water cooling method is to use water to directly contact the mold, which can more effectively transfer heat and thus achieve rapid cooling. However, currently water cooling is usually done manually by spraying water on the outer surface of the mold, which is inefficient, and there is no shielding outside the mold, causing water to splash onto the environment around the mold, resulting in unnecessary cleaning work. Utility Model Content

[0004] In view of the problems existing in the above-mentioned prior art, the present invention provides a mold cooling device for the production of rotational molding raw materials, which can effectively solve the problems existing in the above-mentioned prior art.

[0005] The technical solution of the utility model is:

[0006] According to one aspect of the utility model, the present invention comprises: a cooling chamber, wherein one end of the cooling chamber is provided with a water pipe, wherein a plurality of water outlet nozzles for spraying water on the mold are fixedly provided in the cooling chamber, one end of the water pipe is equipped with a water pump, and the other end is connected to the plurality of water outlet nozzles; an opening is provided at one end of the cooling chamber for allowing the mold to enter;

[0007] The first and second covers are provided on the opening, and are equipped with a first driving device for opening and closing the first and second covers.

[0010] Furthermore, a first groove is provided at one end of the first cover, and a second groove is provided at one end of the second cover. When the first cover and the second cover are closed to each other, the first groove and the second groove form a through hole.

[0011] Furthermore, the first driving device and the second driving device are both electric slide rails.

[0012] Furthermore, it includes at least two connecting members, the first driving device is provided with a first slider and a second slider, the first cover is fixedly connected to the first slider via a connecting member, and the second cover is fixedly connected to the second slider via another connecting member.

[0013] Furthermore, the first driving device is fixed above the second driving device.

[0014] Furthermore, a water spray chamber is provided at the upper end of the cooling chamber, a water pipe is fixedly provided in the water spray chamber, a plurality of water outlet nozzles are distributed at intervals in the water pipe, and the water pipe, the water pipe and the water outlet nozzles are connected.

[0017] Furthermore, the exhaust port is equipped with an exhaust pump.

[0018] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0019] First, this solution can continuously perform water spray cooling operations without manual intervention, thereby improving production efficiency. The closed design of the cooling chamber, the first cover, and the second cover ensures that cooling water will not splash to the outside, thereby avoiding the wet and slippery working environment and potential contamination problems, and helping to maintain a clean and tidy working environment.

[0020] Secondly, the spaced-apart water nozzles can evenly cover the outer surface of the mold with water. By spraying water at intervals, stress concentration and product deformation caused by local overcooling of the mold can be avoided.

[0021] Thirdly, the first inclined portion and the second inclined portion enable the water flow generated during the cooling process to quickly converge and flow to the drain outlet, effectively reducing the residence time of water in the cooling chamber 1 and improving the drainage efficiency.

[0022] Fourth, an exhaust port is provided at one end of the cooling chamber. Preferably, the exhaust port is equipped with an exhaust pump. During cooling, the mold and the plastic inside release a large amount of heat.
