[0038] Furthermore, locking components are provided between the first side panel 12 and the rear panel 13, between the second side panel 18 and the top panel 111, between the second side panel 18 and the rear panel 13, and between the first side panel 12, the top panel 111, the second side panel 18, the rear panel 13 and the upper cover panel 1.

[0039] Furthermore, the locking assembly includes a head base 153, a hinged seat 155 fixed to the head base 153, a locking head 15 connected to the hinged seat 155, a locking ring 154 connected to the locking head 15, a lock base 151, and a hook seat 152 fixed to the lock base 151. The locking ring 154 can hook the hook seat 152 and rotate the locking head 15 to lock it. The lock base 151 is fixed to the upper cover plate 1, the rear plate 13, and the top plate 111. The locking head 15 is arranged on the first side plate 12, the top plate 111, and the second side plate 18 corresponding to the lock base 151. The locking assembly is used to further strengthen the stability of the connection between the outer mold assembly itself or the upper cover plate 1, achieving the function of external fixation. In conjunction with the internal support assembly, this foaming mold adopts an external fixed and internal supported connection method so that the appearance can meet customer needs.

[0040] Furthermore, the wrench 14 assembly is disposed on the front plate 11 and includes a support base 141 fixed to the front plate 11, a wrench 14 rotatably connected to the support base 141, and a connecting plate 142 connected to the front end of the wrench 14. The connecting plate 142 has a clearance hole 1421 for the pipe section 31 of the freezer housing to pass through. The connecting plate 142 is also provided with a locking bolt 143 fixed to the front plate 11. The wrench 14 is connected to the support base 141 by rotation, and the position of the connecting plate 142 can be manually operated. When the pipe section 31 extends out of the front plate 11, the wrench 14 is operated to align the clearance hole 1421 of the connecting plate 142 with the pipe section 31. The wrench 14 is then fixed to the front plate 11 by the locking bolt 143. This assembly is adapted to the components of the freezer housing 3, and the movable wrench 14 assembly can protect the pipe section 31 during assembly.

During assembly, a plastic tube is sleeved on the plastic tube support 1212, so that a hole can be obtained after foaming, which can be used for wiring, etc.

[0042] Furthermore, a certain distance is provided between the outer mold assembly and the inner support assembly, and the freezer housing 3 abuts the inner support assembly. The lower end of the inner support assembly is provided with an inner base 6 that abuts the freezer housing 3. The inner bottom of the outer mold assembly has a lower support block 5 that abuts the lower end of the freezer housing 3. The area between the freezer housing 3 and the outer mold assembly is the foaming zone 4. The inner base 6 is used to support the inner support plate 17, and the lower support block 5 is used to place the freezer housing 3. The foaming zone 4 is the area where the foaming agent flows into, forming the foam layer.

[0043] Principle: This foaming mold first assembles the outer mold component with the freezer shell 3, fixes the pipe section 31 of the freezer shell 3 with the wrench 14 component, and then installs the inner support component into the inside of the freezer shell 3. The upper cover plate 1 seals the upper end and is locked and fixed at each connection by a locking component. Before assembly, a release agent is applied to the inner wall of the outer mold component to solve the problem of demoulding difficulty. The foaming agent is injected into the foaming area 4 through the injection port 101 of the upper cover plate 1 and formed on the freezer shell 3. The exhaust hole 102 is used for exhaust of the foaming area 4 to ensure that each part is filled with foaming agent. This foaming mold perfectly solves the problem of foaming process of this model of freezer.
