Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a refrigerator body foaming mold with a fine-tuning structure. Background Technology

[0002] Refrigerator body foaming refers to the process of injecting foaming materials into the interior of the refrigerator body through a specific process to form a thermal insulation layer. This process is crucial for improving the refrigerator's thermal insulation performance and energy-saving effect. Commonly used foaming materials in refrigerator foaming processes include polyurethane, polyether, and polyester. These materials have good thermal insulation and corrosion resistance properties, which can effectively reduce the transfer of temperature between the inside and outside of the refrigerator and improve the thermal insulation effect.

[0003] Refrigerator manufacturers may produce refrigerators of various specifications according to market demand. Different specifications of refrigerators will use foamed cabinets of different thicknesses. However, the existing mold dimensions are usually fixed and cannot be adjusted, which means that each specification of refrigerator needs to be remanufactured, thereby increasing the production cost of refrigerators. Therefore, a refrigerator cabinet foaming mold with a fine-tuning structure is proposed. Utility Model Content

[0027] Example

[0028] Reference Figure 1 - Figure 4 As an embodiment of the present invention, a refrigerator body foaming mold with a fine-tuning structure is provided, comprising: a processing unit 100 and an adjustment unit 200;

[0029] The processing unit 100 includes a processing table 101, a mold frame 102 fixedly connected to the top of the processing table 101, and two mold blocks 103. A portal frame 104 is fixedly connected to the top of the processing table 101, and an electric telescopic rod 105 is fixedly installed on the top of the inner wall of the portal frame 104.

[0030] The adjustment unit 200 includes a cover plate 201 fixedly connected to the bottom of the output end of the electric telescopic rod 105. A T-shaped rod 202 slides through the top of the cover plate 201. An upper template 203 is fixedly connected to the bottom of the T-shaped rod 202. A threaded rod 204 is rotatably connected to the top of the upper template 203. The threaded rod 204 passes through the cover plate 201 and is threadedly connected to the cover plate 201. Two movable plates 205 are slidably arranged on the inner side of the mold frame 102. Adjustment rods 206 are threadedly connected to both sides of the mold frame 102. The opposite surfaces of the two adjustment rods 206 pass through the mold frame 102 and are rotatably connected to one side of the corresponding movable plate 205. The adjustment unit 200 also includes a fine-tuning component 207 for adjusting the height of the foaming box.

[0031] Specifically, the fine-tuning component 207 includes a groove 2071 opened on the top of each movable plate 205, an adjusting plate 2072 is slidably arranged on the inner side of each groove 2071, and an adjusting bolt 2073 passing through the adjusting plate 2072 is rotatably connected to the top of each adjusting plate 2072, and each adjusting bolt 2073 is threadedly connected to the corresponding movable plate 205.

[0032] Refrigerators typically have two internal cavities: a freezer and a refrigerator. These cavities are formed by two mold blocks 103. When the refrigerator is placed vertically, it is rectangular, causing the main area of ​​the cabinet to be concentrated on the sides and back. The thickness of the foamed cabinet on the sides and back of the refrigerator is different, resulting in different specifications and costs. The upper mold 203 is used to form the back of the cabinet. The distance between the upper mold 203 and the cover plate 201 can be adjusted by rotating the threaded rod 204. The T-shaped rod 202 is used to limit the upper mold 203. The greater the distance between the upper mold 203 and the cover plate 201, the thinner the thickness of the back of the foamed cabinet. By rotating the two adjusting rods 206, the two movable plates 205 can be brought closer together. The two movable plates 205 are used to shape the sides of the foamed cabinet. The closer the distance between the two movable plates 205, the thinner the thickness of the sides of the foamed cabinet.

[0033] The upper template 203 is sized to fit the inner cavity of the mold frame 102, allowing it to be fully inserted into the mold frame 102. The cover plate 201 seals the top of the mold frame 102. After adjusting the mold frame 102, the height of the two adjusting plates 2072 needs to be adjusted. Each of the two adjusting bolts 2073 has a cross-shaped groove at its top for rotating. Rotating the adjusting bolts 2073 allows the adjusting plates 2072 to rise and fall along the slide groove 2071. When the upper template 203 and the cover plate 201... When the distance between them increases, the adjusting plate 2072 is lowered along the slide groove 2071 by rotating the adjusting bolt 2073, so as to shorten the height formed by the adjusting plate 2072 and the movable plate 205 and adapt to the adjusted upper template 203. The top of the adjusting plate 2072 has a circular groove that fits the adjusting bolt 2073, so that the height of the adjusting bolt 2073 will not be higher than the top of the adjusting plate 2072. The thickness of the end of the movable plate 205 with the slide groove 2071 does not exceed five millimeters, so as to meet the error generated by the foaming box.

[0034] After adjustment, the foaming material is injected into the mold frame 102 through the injection device. Then, the cover plate 201 is lowered by the electric telescopic rod 105 to seal the mold frame 102. The foam then expands and forms a box. Two mold blocks 103 can form two inner cavities in the box. After shaping, the cover plate 201 is raised by the electric telescopic rod 105, so that the upper template 203 is removed from the mold frame 102. Then, the foamed box can be removed from the mold frame 102. The thickness of the sides and back of the foamed box can be adjusted by the threaded rod 204, the adjusting rod 206 and the adjusting bolt 2073, so as to meet the needs of refrigerators of different specifications and save refrigerator production costs.

[0035] In addition, a pair of limiting rods 208 are fixedly connected to the bottom of each adjusting plate 2072, and a pair of limiting holes 209 that fit the limiting rods 208 are opened at the bottom of each slide 2071.

[0036] When the adjusting plate 2072 moves up and down within the slide groove 2071, the two limiting rods 208 slide vertically within the two limiting holes 209 respectively. The two limiting rods 208 can improve the stability of the adjusting plate 2072 moving up and down within the slide groove 2071.

[0037] Furthermore, an I-beam plate 106 is slidably provided through the top of the processing table 101, and the top of the I-beam plate 106 is flush with the top of the processing table 101.

[0038] The top of the processing table 101 is provided with a slot that fits the I-beam plate 106. The top of the I-beam plate 106 is completely located in the slot, so that the top of the I-beam plate 106 is flush with the top of the processing table 101, so as not to block the expansion and shaping of the foaming material. The I-beam plate 106 is located between two mold blocks 103. After the foam box is shaped, by pushing the bottom of the I-beam plate 106 upward, the I-beam plate 106 can squeeze the foam box upward, so as to quickly demold the foam box.

[0039] Furthermore, a spring 107 is fitted on the outer wall of the I-beam plate 106. The top of the spring 107 is fixedly connected to the bottom of the processing table 101. A lifting plate 108 is fixedly connected to one side of the cover plate 201. The bottom of the lifting plate 108 is located directly below the I-beam plate 106.

[0040] When the I-beam 106 is pushed upward to demold, the bottom end of the I-beam 106 will squeeze the spring 107. After demolding, the bottom of the I-beam 106 is squeezed by the spring 107, so that the I-beam 106 quickly descends and resets under its own weight and the push of the spring 107. The spring 107 can prevent the I-beam 106 from getting stuck in the slot of the processing table 101.

[0041] When the electric telescopic rod 105 drives the cover plate 201 to rise, the bottom of the lifting plate 108 will contact the bottom end of the I-beam plate 106 and automatically drive the I-beam plate 106 to rise to demold the foam box. The lifting plate 108 enables the I-beam plate 106 to automatically demold the foam box so that workers can take it out.

[0042] During use, the distance between the upper template 203 and the cover plate 201 is adjusted by rotating the threaded rod 204. Then, the distance between the two movable plates 205 is adjusted by rotating the two adjusting rods 206 in sequence. Next, the two adjusting bolts 2073 are rotated in sequence to make the two adjusting plates 2072 descend along their respective slides 2071 to shorten the height formed by the adjusting plates 2072 and the movable plates 205 and to adapt to the adjusted upper template 203. After the adjustment is completed, the foaming material is injected into the mold frame 102 through the injection device. Then, the upper template 203 is inserted into the mold frame 102 by the electric telescopic rod 105, and the upper template 203 is brought into contact with the top of the two adjusting plates 2072.

[0043] After the cover plate 201 seals the mold frame 102, the foaming material is then allowed to expand and form a box. After the molding is completed, the cover plate 201 is raised by the electric telescopic rod 105, so that the upper template 203 is removed from the mold frame 102. When the lifting plate 108 contacts the I-beam plate 106, the lifting plate 108 raises the I-beam plate 106 to demold the foam box. Then the foam box is taken out from the mold frame 102.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
