Description

Technical Field

[0001] This utility model relates to the field of blister molds, and in particular to a blister mold for the production of disposable lunch boxes. Background Technology

[0002] Vacuum forming, also known as thermoforming, is a thermoforming method for thermoplastic materials. It involves clamping sheet or plate material onto the frame of a vacuum forming machine, heating and softening it, and then using a vacuum to adhere it to the mold through air channels on the mold edge. After a short cooling time, the formed plastic product is obtained.

[0003] The prior art patent application with publication number CN219405390U facilitates the introduction of cold water through an inlet pipe, facilitates the storage of cold water in a cooling tank for cooling the lunchbox model, facilitates demolding, and the sealing gasket has a sealing effect on the cooling tank to prevent water leakage. At the same time, the outlet pipe facilitates drainage and allows the water to be recycled. The first and second threaded caps can be rotated to block or disconnect the inlet and outlet pipes. The feed hopper connected to the injection port facilitates material injection.

[0004] The fixed rod facilitates the limiting of the connecting plate, and the rotating threaded cylinder makes it threadedly connected to the threaded groove, which also helps to limit the connecting plate, thus limiting the upper and lower molds. At the same time, the elastic pushing force of the push spring helps to push the connecting plate upward, which helps to separate the upper and lower molds after the lunch box is formed.

[0005] However, current blister molds consist of an upper mold and a lower mold. The size and shape of disposable lunch boxes produced by existing blister molds are fixed, which means that when performing blister molding operations on disposable lunch boxes of different sizes and shapes, it is necessary to use a matching mold. This makes it impossible for blister molds to adapt to the processing of lunch boxes of various sizes and shapes.

[0006] Therefore, it is necessary to provide a blister mold for the production of disposable lunch boxes to solve the above-mentioned technical problems. Utility Model Content
