Under the condition that the refrigeration product needs to be insulated, an insulation box is generally adopted to insulate the refrigeration product so as to ensure that the refrigeration product is in a low-temperature state. The tightness of the insulation can directly affects the insulation performance of the insulation can. The better the sealing property of the heat preservation performance is, the better the heat preservation performance of the heat preservation box is; the worse the tightness of the insulation can, the worse the insulation performance of the insulation can. However, in general, the incubator is formed by assembling, and there is generally a gap between each component of the incubator formed by assembling, thereby causing the sealability of the incubator to be lowered. In addition, in the process of foaming the assembled insulation can, each part of the insulation can needs to be foamed respectively, so that the procedure steps of the foaming process are increased, the cost is increased, and the manufacturing efficiency of the insulation can is low.

In order to improve the above-described technical problems, in other words, in order to improve the technical problem that the increase of the process steps of the foaming process results in the low manufacturing efficiency of the incubator, the foaming mold 10 of the present application is provided.

Wherein the bottom wall 22, the top wall 21, the first sidewall 23, the second sidewall 24, and at least part of the third sidewall 25 are of a double-layer structure, wherein one side is located near one side of the accommodating space 27 and forms an inner container together, and the other side is located near one side of the external space and forms a housing. In the foaming process, foam needs to be injected into a gap between the inner container and the outer shell to complete the foaming process.

It should be noted that the mold core in the prior art cannot enter the accommodating space 27 from the opening 26, so that the foaming process cannot be completed, but the heat insulation box 20 can be disassembled into a plurality of parts to foam the plurality of parts respectively, so as to complete the foaming process.

The second follower 220 drives the second expansion plate 230 to move through the second link assembly 240 when driven by the second driver 210, so that the second expansion plate 230 moves away from or approaches the second follower 220.

The second driving member 210, the second driven member 220, the second expansion plate 230 and the second link assembly 240 are substantially the same as the first driving member 110, the first driven member 120, the first expansion plate 130 and the first link assembly 140 in the first expansion mold core 100, and are not described herein.

In summary, when the foaming process of the insulation can 20 is performed by the foaming mold 10 provided in the embodiment of the present application, the first expansion mold core 100 may be moved away from the second expansion mold core 200, and then the first expansion mold core 100 may be conveniently extended into the inner container; after the first expansion die core 100 stretches into the inner container, the first expansion die core 100 moves relative to the frame 300 to drive the heat insulation box 20 to move, so that the second expansion die core 200 stretches into the inner container, and the inner wall of the inner container can be propped against the first expansion die core 100 and the second expansion die core 200; simultaneously, the outer side of the outer shell is pressed by the plurality of first pressing pieces 400, so that the stability of the inner container and the outer shell can be ensured in the foaming process, and the foaming process can be effectively performed. The integral insulation can 20 can be ensured to be directly foamed integrally, and a plurality of process steps for foaming all parts of the insulation can 20 can be omitted, namely, the steps of the foaming process can be reduced, so that the technical problem of low manufacturing efficiency caused by complex manufacturing process of the insulation can 20 in the prior art is solved. In general, from the aspect of technical innovation and advancement, the technical scheme of the application perfectly realizes that the integral type heat preservation box 20 directly carries out integral foaming, effectively avoids the technical defect that the cooling capacity loss is overlarge after the box body is split and foamed and then integrally forms, improves the sealing property and heat preservation property of the heat preservation box 20, and ensures the refrigeration effect and performance of refrigeration products.

The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present invention should be included in the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
