[0046] For the convenience of description, without special instructions, the orientation description of up, down, left, right, front, back in this paper is based on the state of the refrigerator when it is used, the door body of the refrigerator is front, and the opposite direction is back, and the vertical direction is up and down.

[0047] At present, the door lining of the door of the refrigerator mostly relies on manual edge cutting, which has large manual labor and the manual edge cutting is easy to damage the door lining, causing the door lining to be scrapped. In order to reduce labor cost and improve product quality, it is the trend of the refrigerator industry to use automatic edge cutting machine to realize automatic edge cutting of the door lining. However, the existing edge cutting machine has the problem of inaccurate positioning of the door lining and the edge cutting platform during automatic conveying of the door lining, which causes the door lining to be scrapped due to subsequent edge cutting.

[0048] Reference Figure 1 , Figure 2 and Figure 3The mold assembly provided by the embodiment of the present application is used for cutting a door liner of a refrigerator and comprises a lower mold 100 and an upper mold 200. The lower mold 100 comprises a base 10 and a floating table 20 arranged on the base 10. The floating table 20 is provided with a placing groove 201 for placing the door liner and a cutting blade 202 arranged around the outer periphery of the placing groove 201. The lower mold 100 further comprises a movable limiting structure 1 for enabling the floating table 20 to be offset in the horizontal direction relative to the base 10, and a buffer assembly 3 for enabling the floating table 20 to be elastically stretched and contracted in the thickness direction relative to the base 10. The floating table 20 can also be translated in the horizontal direction relative to the base 10. The upper mold 200 comprises a pressing table 30 for pressing the floating table 20.

[0049] Specifically, the cutting process of the door liner is as follows: the door liner is placed in the placing groove 201 on the floating table 20, and the edge scraps of the door liner will be extended outward beyond the cutting blade 202; then the relative movement of the upper mold 200 and the lower mold 100 is controlled, the pressing table 30 is pressed against the floating table 20, and the cutting blade 202 can cut the edge of the door liner, so as to cut off the edge scraps of the door liner.

[0050] In an embodiment of the present application, it can be understood that the upper mold 200 and the lower mold 100 of the present application are specifically applied to an automatic and digital automatic edge cutting machine. The edge cutting machine has a power system (such as a mechanical hand, a movable platform, a hydraulic system) and an electric control system for controlling the pressing and punching of the upper mold 200 and the lower mold 100. For example, the mechanical hand automatically picks up the door liner and transports the door liner to the lower mold 100 for positioning, and drives the relative movement of the lower mold 100 and the upper mold 200 to punch and cut the edge of the door liner, so as to realize automatic edge cutting operation. The structure of the automatic edge cutting machine is not described herein.

[0051] The mold assembly of the present application has the following advantages. The floating table 20 can be elastically stretched and contracted in the stacking direction (Y direction in the figure) relative to the base 10, which is beneficial to buffering and protecting the floating table 20 and improving the stability during the pressing and punching process of the upper mold 200 and the lower mold 100. The floating table 20 can also be offset in the horizontal direction relative to the base 10. When the mold assembly is used for cutting, the door liner is initially placed on the floating table 20. During the movement of the lower mold 100, the floating table 20 can slightly shake relative to the base 10. Through the shaking of the floating table 20 and the gravity of the door liner, the door liner can fall into the placing groove 201, so as to realize accurate positioning of the door liner and the floating table 20 and ensure the subsequent punching and cutting effect.

[0052] Reference Figure 2 and Figure 5In some embodiments, the activity limiting structure 1 comprises a slot 102 arranged on one of the floating platform 20 or the base platform 10, and a limiting rod 101 arranged on the other of the floating platform 20 or the base platform 10, the limiting rod 101 being arranged to be capable of horizontal movement in the slot 102.

[0053] Specifically, the floating platform 20 and the base platform 10 are arranged in a rectangular structure and in a horizontal direction, and in a horizontal cross-section, the size of the slot 102 is larger than that of the limiting rod 101, so that there is a gap between the outer wall of the limiting rod 101 and the inner wall of the slot 102, and thus the limiting rod 101 can be slightly moved in the horizontal direction in the slot 102, so that the floating platform 20 can be offset relative to the base platform in the horizontal direction.

[0054] It can be understood that the number of limiting rods 101 can be set to be multiple, and the number of slots 102 is correspondingly arranged. By arranging multiple limiting rods 101 in each slot 102, the limiting rod 101 and the slot 102 can only allow the floating platform 20 to be slightly offset in the horizontal direction, and effectively limit the floating platform 20 from being separated from the base platform 10 in the horizontal direction, so that the floating platform 20 and the base platform 10 are structurally stable.

[0055] Preferably, referring to Figure 2 , four slots 102 are arranged on a single floating platform 20 in a rectangular arrangement, and four limiting rods 101 are correspondingly arranged on the base platform 10, so that the floating platform 20 and the base platform 10 can be quickly positioned and assembled by the positioning and cooperation of the limiting rod 101 and the slot 102, which is beneficial to the structural assembly.

[0056] Referring to Figure 2 , in a specific embodiment, the limiting rod 101 is in a cylindrical structure, and the slot 102 is in a circular slot.

[0057] It can be understood that by using the eccentric movement of the limiting rod 101 in the slot 102, the floating platform 20 can be offset relative to the base platform 10 in any direction on the horizontal plane, and the offset range is larger.

[0058] Referring to Figure 1 and Figure 2 , in some embodiments, the floating platform 20 is provided with a slot 102, the base platform 10 is provided with a limiting rod 101 arranged in the slot 102, and the top end of the limiting rod 101 is further provided with an anti-disengagement structure 2.

[0059] Specifically, after the limiting rod 101 is arranged in the slot 102, the anti-disengagement structure 2 is arranged at the top end of the limiting rod 101, which effectively limits the floating platform 20 from being separated from the floating platform 20 in the stacking direction, so that the floating platform 20 is stably stacked on the base platform 10.

[0060] In one specific embodiment, the anti-disengagement structure 2 comprises a limiting cap body which is connected to the top end of the limiting rod 101 by a screw.

[0061] With reference to Figure 2 , Figure 3 and Figure 4 , in some embodiments, the base 10 is provided with a mounting hole 4, and the buffer assembly 3 comprises an elastic member 302 arranged in the mounting hole 4 and a supporting member 301 arranged at the top end of the elastic member 302, the supporting member 301 protruding upwardly from the base 10 and abutting against the floating table 20.

[0062] Specifically, the elastic member 302 is capable of telescopic movement in the mounting hole 4, so that the supporting member 301 is capable of telescopic movement in the stacking direction. The supporting member 301 protrudes upwardly from the base 10 and abuts against the bottom end of the floating table 20. With reference to Figure 3 , there is a gap between the bottom surface of the floating table 20 and the top surface of the base 10, and then when the upper die 200 and the lower die 100 move relatively to perform stamping and cutting, the elastic member 302 and the supporting member 301 can buffer and protect the floating table 20, effectively reducing the impact force and vibration.

[0063] In one specific embodiment, the elastic member 302 is a spring; and the supporting member 301 is a steel ball, which has high strength and rigidity and can withstand a large load.

[0064] Further, the floating table 20 is capable of elastic movement in the stacking direction relative to the base 10 through the buffer assembly 3, and the floating table 20 is capable of offset in any direction on the horizontal plane relative to the base 10 through the movable limiting structure 1, so that the floating table 20 can be slightly shaken relative to the base 10. During the trimming process, some door cans cannot be completely embedded in the placing groove 201 due to errors after being placed on the floating table 20; the die 100 is moved as a whole by the driving system of the trimming machine (or the floating table 20 is further controlled to produce micro-movement), so that the floating table 20 is shaken relative to the base 10, and the door cans on the floating table 20 can fall into the placing groove 201 completely under the action of their own gravity, ensuring accurate positioning of the door cans and the floating table 20 and guaranteeing the subsequent stamping and cutting effect.

[0065] With reference to Figure 2 , in some embodiments, the floating table 20 comprises at least a first support layer 5, a second support layer 6 and a third support layer 7 which are stacked, the placing groove 201 is formed in the first support layer 5, the top surface of the second support layer 6 forms the bottom wall of the placing groove 201, and the cutting blade 202 is arranged on the second support layer 6.

[0067] In some embodiments, the second support layer 6 is made of metal material.

[0068] It can be understood that the cutting blade 202 is provided on the second support layer 6, so the second support layer 6 needs to ensure that the structure is firm to ensure that the cutting blade 202 can perform the edge cutting work.

[0069] Continuing to refer to Figure 2 In some embodiments, the second support layer 6 is further provided with an edge pressing boss 8 close to the cutting blade 202; the length direction of the edge pressing boss 8 is consistent with the length direction of the cutting blade 202. It can be understood that the door liner is placed in the placing groove 201, and the edge pressing boss 8 is used to provide support for the edge of the door liner, and the edge pressing boss 8 ensures the edge tension of the door liner when edge cutting, and the edge cutting quality is better.

[0070] Specifically, the placing groove 201 has a rectangular structure, and the four sides of the placing groove 201 are provided with the cutting blade 202, and the edge pressing boss 8 close to the cutting blade 202 is provided at each side.

[0071] In other embodiments, the first support layer 5 is made of solid wood or resin material. It has good buffering property, and the first support layer 5 can relieve the stress between the floating table 20 and the pressing table 30, avoiding damage to the product in the stamping and cutting process. The third support layer 7 is made of solid wood or resin material, and the third support layer 7 can relieve the stress between the floating table 20 and the base table 10, avoiding damage to the product in the stamping and cutting process.

[0072] Further, the base table 10 is composed of a plurality of laminated structures, and each laminated structure is made of solid wood or resin material, so that the base table 10 has good support and buffering properties.

[0073] In one specific embodiment, the base table 10 includes three laminated structures, from top to bottom, the base table 10 includes a wood layer, a wood layer, and a resin layer which are sequentially laminated. The floating table 20 includes a wood layer, a movable stainless steel layer, and a resin layer which are sequentially laminated from top to bottom.

[0074] Referring to Figure 6In some embodiments, the upper mold 200 is also composed of a multi-layer laminated structure, from top to bottom, the upper mold 200 includes wood layer, stainless steel layer, wood layer, resin layer, stainless steel layer which are sequentially laminated; wherein the bottommost stainless steel layer forms the bottom surface of the pressing table 30, for pressing with the floating table 20. The upper mold 200 adopts a multi-layer structure laminated, which has good structural stability.

[0075] With reference to Figure 1 and Figure 2 , the base table 10 is provided with at least two floating tables 20 arranged side by side, and the upper mold 200 is provided with a pressing table 30 corresponding to the number of floating tables 20.

[0076] It can be understood that the base table 10 is provided with two or more floating tables 20, and each floating table 20 on the base table 10 can edge the door liner; and the base table movement can drive the movement of the plurality of floating tables 20, which can be applied in the edge cutting machine to simultaneously edge a plurality of door liners, greatly improving the processing efficiency.

[0079] The first weight-reducing hole structure 110 is located in the placement groove 201 and does not affect the arrangement of the cutting blade 202. The size of the second weight-reducing hole structure 210 is greater than that of the first weight-reducing hole structure 110, so that the pressing table 30 and the floating table 20 can be pressed to edge the door liner.

[0080] The above is only a preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
