Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a vacuum forming mold for a box liner. Background Technology

[0002] The inner liner of refrigerators, freezers and other home appliances is generally manufactured using vacuum forming technology. The core of this process is to use a vacuum forming mold to absorb heated and softened plastic sheets onto the surface of the mold, and then cool and solidify them to form the desired shape.

[0003] Currently, existing molds require the application of a release agent (such as silicone oil) manually or through fixed nozzles before vacuum forming. However, manual spraying is prone to missed areas or uneven coating thickness, while fixed nozzles cannot cover complex curved surfaces, leading to localized missing release agents. Uneven distribution of the release agent can cause the vacuum-formed box liner to adhere too tightly to the mold surface, requiring additional external force during demolding, which may cause product deformation or surface scratches, severely impacting yield and production efficiency.

[0004] Therefore, this application provides a vacuum forming mold for a box liner to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a box liner vacuum forming mold to solve the problem that the existing box liner vacuum forming mold is not convenient for the auxiliary workers to spray the release agent quickly and evenly, which affects the coating effect and thus the release effect.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A box liner thermoforming mold includes a mold body, a fixed base is fixed around the bottom edge of the mold body, a receiving groove is formed around the outer edge of the fixed base, a movable frame is rotatably installed in the receiving groove, the movable frame moves in a semi-circular arc along the top of the mold body, and a plurality of nozzles are provided on the inner side of the movable frame, and a connecting pipe for external release agent is fixed to one outer end of the movable frame.

[0008] The mold body is hollow inside, and the top surface of the mold body is covered with a cooling block. Cooling channels are distributed inside the cooling block, and a cooling water connection port connecting the cooling channels is fixed on the surface of the cooling block.

[0009] Optionally, the receiving groove is an annular groove, and the movable frame is a "C"-shaped structure adapted to fit half of the receiving groove.

[0010] Optionally, the two ends of the movable frame are rotatably mounted at the middle of the two ends of the receiving groove, and both ends of the movable frame are provided with a fixed cylinder, and a fixing pin is fitted inside the fixed cylinder to form a rotatable installation.

[0011] Optionally, the inner side of the movable frame is provided with a groove, the nozzle is installed in the groove, and the interior of the movable frame is hollow, connecting the nozzle and the connecting pipe.

[0012] Optionally, the surface of the mold body is provided with a plurality of air extraction holes, and an air extraction pipe connected to the air extraction holes is fixed inside the mold body.

[0013] Optionally, a connecting plate is fixed in the middle of the mold body. The connecting plate is hollow inside. One side of the connecting plate is connected to a plurality of the air extraction pipes, and the other side is fixed with a vacuum connection port.

[0014] Optionally, the cooling channels are evenly distributed back and forth in an "S" shape inside the cooling block, and there are two cooling water connection ports, which are respectively connected to the two ends of the cooling channels.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above solution, thanks to the movable frame, it is convenient to connect the release agent to the outside through the connecting pipe. When the movable frame moves along a semi-circular arc trajectory above the mold body, the release agent is evenly sprayed onto the surface of the mold body through the nozzle, which is conducive to the rapid demolding after the box liner is vacuum formed and is easy to use.

[0017] In the above solution, thanks to the setting of the cooling block, the cooling channel and the cooling water connection port can be used to connect the cooling water to form a cooling mechanism, so as to quickly cool the surface of the mold body, thereby improving the cooling and curing speed after the vacuum forming of the box liner and improving the processing efficiency.

[0018] In summary, this device not only facilitates the rapid and uniform application of release agent, which is beneficial for demolding the box liner, but also enables rapid cooling and curing of the molded box liner, improving processing efficiency and resulting in good overall performance.
