Description

Technical Field

[0001] This utility model relates to the field of refrigerator manufacturing, and more specifically, to a tooling for assisting in the pressing of a refrigerator evaporator. Background Technology

[0002] For refrigerators with integrated linings and integrated evaporators, during the evaporator pressing process, the evaporator on the back of the refrigerator compartment can be automatically pressed using a pressing machine. However, due to space limitations, the sides of the freezer lining cannot be pressed using a pressing machine and must be pressed manually. This can easily lead to uneven pressing force between the evaporator and the freezer lining, causing weak adhesion and easy detachment. After foaming, the evaporator is prone to localized gas accumulation and delamination, resulting in significant energy loss and affecting the refrigerator's cooling performance. Furthermore, the lining is more susceptible to damage from impacts and wrinkles, causing waste and impacting production efficiency. Utility Model Content

[0003] To overcome the aforementioned shortcomings in the prior art, the purpose of this utility model is to provide a tooling for assisting in the pressing of a refrigerator evaporator. This tooling provides support for the pressing of the evaporator, thereby facilitating a tight pressing of the evaporator and the inner liner. The embodiments of this utility model can overcome the problems of wrinkles in the inner liner and loose pressing after pressing in existing pressing methods, and are characterized by convenient operation, while also helping to improve the product pressing qualification rate.

[0004] This utility model provides a tooling for assisting in the pressing of a refrigerator evaporator. This tooling is used in the manufacture of a refrigerator, which includes an evaporator and a freezer liner. The tooling for assisting in the pressing of the refrigerator evaporator evaporator is used to press the evaporator onto the freezer liner. The tooling includes a tooling table, a tooling mold, and a tooling fixing component. The tooling fixing component is detachably connected to the tooling mold and the tooling table, and is used to fix the tooling mold on the tooling table. The tooling mold has a pressing support surface, which supports the freezer liner and mates with it to press the evaporator onto the freezer liner. The tooling fixing component can fix the tooling mold to the tooling table, which provides placement and support for the freezer liner. The tooling mold mates with the freezer liner; that is, the freezer liner can be placed on the tooling mold and supported by the pressing support surface. When pressing the evaporator onto the refrigeration liner, the pressing support surface can support the refrigeration liner, thereby allowing the evaporator to be pressed more firmly onto the refrigeration liner. In this embodiment of the invention, the evaporator is bonded to the refrigeration liner, and the tooling liner mold placed under the refrigeration liner can provide good support for the refrigeration liner, thereby making the evaporator and the refrigeration liner tightly bonded and not easy to fall off, while also avoiding the problem of the refrigeration liner being bumped and wrinkled.

[0005] Furthermore, in an optional embodiment, the tooling liner includes a liner body and a liner mounting portion connected to each other, the liner body having the pressing support surface, and the liner mounting portion being detachably connected to the tooling table via the tooling fastener.

[0006] Furthermore, in an optional embodiment, the liner body protrudes from the liner mounting portion and is used to extend into the cavity of the freezing liner so that the freezing liner can fit against the pressing support surface.

[0007] Furthermore, in an optional embodiment, the freezing liner has an inner surface, and the pressing support surface corresponds to the inclination angle of the inner surface.

[0008] Furthermore, in an optional embodiment, the mold mounting portion is provided with a mold mounting hole, through which the mold tooling fastener passes and connects to the tooling table. The mold mounting hole allows for convenient installation of the tooling fastener to secure the mold and the tooling table.

[0009] Furthermore, in an optional embodiment, the liner mounting hole is arranged around the outer periphery of the liner body.

[0010] Furthermore, in an optional embodiment, the mold liner fixture fixing component is a screw or bolt, which passes through the mold liner mounting hole and is connected to the fixture table.

[0011] Furthermore, in an optional embodiment, the pressing support surface includes two surfaces, which respectively mate with the two sides of the freezing liner to press the evaporator onto the two sides of the freezing liner.

[0012] Further, in an optional embodiment, the evaporator includes a back evaporator and a side evaporator, the back evaporator being mounted on the refrigerator liner, the side evaporator being mounted on the freezer liner, and the pressing support surface being used to support the freezer liner and cooperate with the freezer liner to press the evaporator onto the freezer liner.

[0013] Furthermore, in an optional embodiment, the tooling table is provided with an assembly part, and the tooling liner is mounted on the assembly part.

[0014] In existing technologies, the back evaporator is glued and pressed onto the back of the refrigerator liner, while the side evaporators are glued to the sides of the freezer liner. After gluing, a pressing machine is used to press the back evaporator tightly onto the refrigerator liner. However, due to space constraints, the side evaporators can only be manually pressed onto the freezer liner, which easily leads to loose bonding and wrinkles in the freezer liner during pressing. This pressing method in the above-mentioned existing technology is greatly affected by human factors, the liner is prone to wrinkling after pressing, and the side evaporators cannot be tightly bonded to the liner. After foaming, the evaporators are prone to local gas accumulation and debonding, resulting in significant energy loss and affecting the cooling effect.

[0015] Compared with the prior art, this utility model has the following advantages: The tooling for assisting in the pressing of the refrigerator evaporator includes a tooling table, a tooling mold, and a tooling fixing component. The tooling fixing component is detachably connected to the tooling mold and the tooling table, and is used to fix the tooling mold on the tooling table. The tooling mold has a pressing support surface, which is used to support the freezing liner and cooperate with the freezing liner to press the evaporator onto the freezing liner. The tooling fixing component can fix the tooling mold to the tooling table, which can provide placement and support for the freezing liner. The tooling mold is used to cooperate with the freezing liner, that is, the freezing liner can be placed on the tooling mold and supported by the pressing support surface. When pressing the evaporator onto the freezing liner, the pressing support surface can support the freezing liner, thereby enabling the evaporator to be pressed more firmly onto the freezing liner. In this embodiment of the invention, the evaporator is bonded to the freezing liner. The tooling liner placed under the freezing liner can provide good support for the freezing liner, thereby making the evaporator and the freezing liner bond tightly and not easy to fall off. At the same time, it also avoids the problem of the freezing liner being bumped and wrinkled.

[0016] Meanwhile, a positioning tooling mold can be designed according to the shape of the refrigeration liner. The tooling mold and tooling table work together to ensure the flatness of the refrigeration liner surface during evaporator pressing and fixing, resulting in high conformity between the evaporator and the refrigeration liner during mass production. Furthermore, the tooling mold and tooling table can be detachably connected via tooling fasteners. The tooling mold has a universal structure, suitable for production of various liner sizes. In addition, the tooling mold and tooling table are assembleable and detachable, allowing for horizontal, vertical, and other height adjustments to meet the requirements of operators of different heights and with different operating habits.

[0027] Please see Figure 1 This invention provides a tooling 100 for assisting in the pressing of a refrigerator evaporator. This tooling 100 assists in the pressing of the refrigerator evaporator, improving the pressing effect between the evaporator and the freezer liner 220. This invention provides support for the pressing of the evaporator, facilitating a tighter pressing of the evaporator and the liner. This invention overcomes the problems of liner wrinkling and loose pressing in existing pressing methods, and is easy to operate, while also improving the product pressing pass rate.

[0028] like Figure 1 and Figure 2 As shown in this embodiment of the present invention, the auxiliary refrigerator evaporator pressing tool 100 is used for manufacturing a refrigerator. The refrigerator includes an evaporator and a freezer liner 220. The auxiliary refrigerator evaporator pressing tool 100 is used to press the evaporator onto the freezer liner 220. The auxiliary refrigerator evaporator pressing tool 100 includes a tooling table 110, a tooling mold 120, and a tooling fixing member 130. The tooling fixing member 130 is detachably connected to the tooling mold 120 and the tooling table 110 and is used to fix the tooling mold 120 onto the tooling table 110. The tooling mold 120 has a pressing support surface 121, which is used to support the freezer liner 220 and cooperate with the freezer liner 220 to press the evaporator onto the freezer liner 220.

[0029] It should be noted that, in this embodiment of the invention, the tooling mold 120 can be fixed on the tooling table 110 by the tooling fastener 130. The tooling table 110 can provide placement and support for the freezing liner 220. The tooling mold 120 is used to cooperate with the freezing liner 220, that is, the freezing liner 220 can be placed on the tooling mold 120 and supported by the pressing support surface 121. When pressing the evaporator onto the freezing liner 220, the pressing support surface 121 can support the freezing liner 220, thereby enabling the evaporator to be pressed more firmly onto the freezing liner 220. In this embodiment of the invention, the evaporator is bonded to the freezing liner 220. The tooling mold 120 placed under the freezing liner 220 can provide good support for the freezing liner 220, thereby making the evaporator and the freezing liner 220 bond tightly and not easy to fall off, while also avoiding the problem of the freezing liner 220 being bumped and wrinkled.

[0030] Furthermore, it should be noted that in this embodiment of the invention, tooling molds 120 of corresponding sizes can be prepared for different models and sizes of freezer liners 220. These tooling molds 120 can be mounted on the tooling table 110 via tooling fasteners 130, thereby achieving matching of freezer liners 220 of different sizes and providing pressing support for freezer liners 220 of different sizes. Simultaneously, in this embodiment of the invention, the tooling molds 120 and the tooling table 110 are detachably connected via tooling fasteners 130, allowing for convenient horizontal, vertical, and other height adjustments, thus meeting the needs of operators of different heights and operating habits, and improving the applicability of the tooling.

After gluing, a pressing machine is used to press the back evaporator 211 tightly onto the freezer liner. However, due to space constraints, the side evaporators 212 can only be manually pressed onto the freezer liner 220, which easily leads to loose pressing and wrinkles in the freezer liner 220. This pressing method in the prior art is highly susceptible to human error, easily causing wrinkles after pressing. Furthermore, the side evaporators 212 cannot be tightly adhered to the liner, and after foaming, localized gas accumulation and detachment of the evaporator can occur, resulting in significant energy loss and affecting the refrigeration effect. In this embodiment of the invention, the tooling liner 120 and the pressing support surface 121 provided on the tooling liner 120 can support the freezing liner 220, so that when the evaporator is pressed onto the freezing liner, the evaporator can be tightly pressed onto the freezing liner 220.

[0033] In this embodiment of the invention, a positioning tooling mold 120 can be designed according to the shape of the refrigeration liner 220. The tooling mold 120 and the tooling table 110 are used together to ensure the flatness of the refrigeration liner surface when the evaporator is pressed and fixed, and to ensure high conformity between the evaporator and the refrigeration liner during mass production. Meanwhile, the tooling mold 120 and the tooling table 110 can be detachably connected through the tooling fastener 130. The tooling mold 120 has a universal structure and can be used for the production of various liner sizes. Furthermore, the tooling mold 120 and the tooling table 110 can be assembled and disassembled, and can be adjusted to different heights, such as horizontal or vertical, to meet the requirements of operators with different heights and operating habits.

[0034] In an optional embodiment, the tooling mold 120 includes a mold body 122 and a mold mounting portion 123 connected to each other. The mold body 122 has a pressing support surface 121, and the mold mounting portion 123 is detachably connected to the tooling table 110 via a tooling fastener 130. Optionally, in this embodiment, the mold body 122 and the mold mounting portion 123 are integrally formed. Of course, this is not the only option. In other embodiments of this invention, the mold body 122 and the mold can be manufactured and connected in other ways, and this invention does not impose specific requirements or limitations on these aspects.

[0035] like Figure 1 As shown, further, in this embodiment, the liner body 122 protrudes from the liner mounting portion 123 and is used to extend into the cavity of the freezing liner 220 so that the freezing liner 220 can fit against the pressing support surface 121.

Optionally, the tooling fastener 130 can be a bolt or a screw. The mold tooling fastener 130 is a screw or bolt, which passes through the mold mounting hole 1231 and is connected to the tooling table 110.

[0038] Optionally, in this embodiment, the liner mounting hole 1231 is arranged around the outer periphery of the liner body 122 so as to fix the tooling liner 120 at multiple angles, thereby ensuring stability.

[0039] In this embodiment, there are two pressing support surfaces 121, which respectively cooperate with the two sides of the freezing liner 220 to press the evaporator onto the two sides of the freezing liner 220.

[0040] In this embodiment, the evaporator includes a back evaporator 211 and a side evaporator 212.
