Under the condition that the refrigeration product needs to be insulated, the insulation box is usually adopted to insulate the refrigeration product so as to ensure that the refrigeration product is in a low-temperature state. The sealing performance of the insulation can has a direct influence on the insulation performance of the insulation can. The better the sealing performance of the heat insulation performance is, the better the heat insulation performance of the heat insulation box is; the poorer the sealing property of the heat-insulating box, the poorer the heat-insulating performance of the heat-insulating box. However, in general, the incubator is formed by assembling, and gaps are generally formed between the respective parts of the assembled incubator, which results in a reduction in the sealing performance of the incubator. In addition, in the assembled thermal insulation box, each component of the thermal insulation box needs to be foamed during the foaming process, so that the process steps of the foaming process are increased, the cost is increased, and the manufacturing efficiency of the thermal insulation box is low.

In order to solve the above-mentioned problems, in other words, to solve the problem that the manufacturing efficiency of the incubator is low due to the increase of the number of steps in the foaming process, the foaming mold 10 of the present application is provided.

It should be noted that the foaming mold 10 of the present application can be applied to a general open-type incubator 20 to perform a foaming process, and can also be applied to an integrated incubator 20 to perform a foaming process. In the embodiment of the present application, the incubator 20 shown in fig. 1 is taken as an example, and the incubator 20 includes a top wall 21, a bottom wall 22, a first side wall 23, a second side wall 24, and two third side walls 25. The top wall 21 is connected to the top of the two third side walls 25, and the width of the top wall 21 is smaller than that of the third side walls 25; the bottom wall 22 is connected to the middle of the two third side walls 25, and the width of the bottom wall 22 is equal to the width of the third side walls 25; the first sidewall 23 is connected between the top wall 21 and the bottom wall 22, and two sides of the first sidewall 23 are respectively connected with the two third sidewalls 25; two sides of the second sidewall 24 are respectively connected to the two third sidewalls 25, and one side of the second sidewall 24 is connected to the bottom wall 22, and an opening 26 is formed between the other side and the top wall 21; the opening 26 communicates with a receiving space 27 enclosed by the top wall 21, the bottom wall 22, the first side wall 23, the second side wall 24 and the two third side walls 25. The bottom wall 22, the top wall 21, the first sidewall 23, the second sidewall 24, and at least a portion of the third sidewall 25 are of a double-layer structure, wherein one layer is located at a side close to the accommodating space 27 and forms a liner together, and the other layer is located at a side close to the external space and forms a housing. In the foaming process, the gap between the inner container and the outer shell needs to be foamed 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, and only the heat preservation box 20 is disassembled into a plurality of parts to respectively foam the plurality of parts, thereby completing the foaming process. However, the foaming mold 10 provided in the present application can directly assist the above-mentioned integrated thermal insulation box 20 to directly foam, and can omit a plurality of process steps for foaming each component of the thermal insulation box 20, i.e. reduce the steps of the foaming process, so as to solve the technical problem in the prior art that the manufacturing process of the thermal insulation box 20 is complicated and the manufacturing efficiency is low.

Under the condition that the first expansion mold core 100 extends into the liner, the first expansion mold core 100 is further used for driving the incubator 20 to move away from the second expansion mold core 200, so that the second expansion mold core 200 is separated from the liner; and is also used for driving the heat preservation box 20 to move close to the second expansion mold core 200, so that the second expansion mold core 200 extends into the inner container. The first pressing members 400 are movably connected to the frame 300, and the first pressing members 400 are used for pressing the sides of the housing.

The integrated heat preservation box 20 can be ensured to be directly foamed integrally, multiple process steps of foaming each part of the heat preservation box 20 can be omitted, namely, the steps of the foaming process can be reduced, and the technical problem that the manufacturing efficiency is low due to the complex manufacturing process of the heat preservation box 20 in the prior art is solved. In general, from technical innovation and progress, the technical scheme perfectly realizes that the integrated heat preservation box 20 directly carries out integral foaming, effectively avoids the technical defect of overlarge loss of cooling capacity when the box body is formed into a whole after being foamed in a split manner, improves the sealing property and the heat preservation property of the heat preservation box 20, and ensures the refrigerating effect and the performance of a refrigerating product.

After the foaming process is completed, the first expansion core 100 is moved away from the second expansion core 200 so that the second expansion core 200 can be removed from the accommodating space 27 from the outlet; the completely foamed heat-insulating box 20 is then moved so that the first expansion mold core 100 is removed from the accommodating space 27, and the heat-insulating box 20 can be completely removed. Therefore, the purposes of saving process steps and improving the manufacturing efficiency of the incubator 20 can be achieved.
