Description

Technical Field

[0001] The utility model relates to the technical field of foam mold processing, in particular to a cooling device for a foam mold. Background Art

[0002] Foam packaging is a packaging product made of foam material, usually used to protect the contents. The so-called foam packaging mainly refers to the packaging product made of expandable polystyrene raw materials through molds and heat processing, and the packaging product is commonly known as "foam". Expandable polystyrene is an ideal packaging material. Through the molding process, it can be processed into packaging products of various shapes and thicknesses according to needs.

[0003] A Chinese patent discloses a cooling device for a foam mold, with publication number CN217944062U, comprising a fixed frame; a lower mold is detachably mounted on the middle part of the inner wall at the bottom end of the fixed frame, an electro-hydraulic push rod is fixedly connected to the middle part of the inner wall at the top end of the fixed frame by bolts, the telescopic end of the electro-hydraulic push rod is fixedly connected to the middle part of the upper surface of the push plate, and an upper mold is detachably mounted on the middle part of the bottom side of the push plate, which is combined with a push plate, a pull rod, a piston, a piston cylinder, a water injection pipe, a drainage pipe, a through pipe and a nozzle. When the electro-hydraulic push rod pushes the upper mold to move downward for foam production, water in the water tank can be pumped into the piston cylinder. After the foam is formed, the electro-hydraulic push rod drives the upper mold to move upward and reset, and the water in the piston cylinder can be sprayed out through the nozzle connected to the through pipe, so as to further automatically cool the foam in the lower mold, which is beneficial to the forming and demolding of the foam.

[0004] However, there are still the following disadvantages: when the cooling device of the foam mold is in use, it is not possible to quickly cool the foam mold by water cooling, and flushing with a nozzle can easily cause deformation of the mold, so a cooling device for the foam mold is designed.
