DETAILED DESCRIPTION
[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0023] See also Figure 1-6 As shown, the refrigerator rear cover rotary bending table includes an upper mold assembly and a lower mold assembly, wherein the upper mold assembly and the lower mold assembly cooperate with each other to realize the bending process of the refrigerator rear cover. Specifically, the lower mold assembly includes an adjustment motor 5, which is fixedly mounted on the frame, and a lower mold bracket 4 is fixed at the output end of the adjustment motor 5, wherein a mold cavity 3 for molding is opened on the lower mold bracket 4, and the shape of the mold cavity 3 is preliminarily adapted to the shape of the processed rear cover 9; the upper mold assembly includes a first telescopic rod 1, which is fixedly mounted on the upper mold bracket 2, and a connecting frame 8 is fixed to the upper mold bracket 2, wherein an inner positioning assembly 7 for limiting the raw material is arranged on the side of the connecting frame 8, and an inner pressure plate 6 is fixed at the output end of the first telescopic rod 1 , wherein the inner pressure plate 6 and the mold cavity 3 cooperate with each other. When in use, the inner positioning component 7 is used to position the raw material in real time, and the inner pressure plate 6 is controlled to move longitudinally by starting the first telescopic rod 1, so that the inner pressure plate 6 enters the mold cavity 3 and molds the raw material, thereby obtaining the finished processed rear cover 9. The start of the adjustment motor 5 can control the rotation of the lower mold bracket 4, so that after the heavy pressure on the processed rear cover 9 is completed, the lower mold bracket 4 is rotated from the original direction until the finished processed rear cover 9 is taken out of the mold cavity 3. Therefore, in this application, the adjustment motor 5 does not have to be located at the center position of the lower mold bracket 4, so as to facilitate the deviation of the lower mold bracket 4 and the upper mold bracket 2, so as to facilitate the blanking of the processed rear cover 9.
[0024] As a further embodiment of the present application, since there is space between the lower mold support 4 and the connecting frame 8, it is used to enable the entry of raw materials, that is, the connecting frame 8 and the lower mold support 4 are used to perform preliminary positioning of the raw materials, and the internal positioning component 7 is used to achieve further positioning of the raw materials, so as to achieve stable entry of the raw materials between the lower mold support 4 and the connecting frame 8.
[0025] Specifically, the internal positioning component 7 includes a symmetrically arranged limit rod 11, and a positioning plate 12 is fixed on the limit rod 11. When in use, the position of the limit rod 11 on the connecting frame 8 is controlled to control the distance between adjacent positioning plates 12, so that the raw material can pass through between adjacent limit positioning plates 12, so that the edge position of the raw material can be limited between the positioning plates 12. When the raw material enters from one end of the connecting frame 8, the connecting frame 8 and the lower mold support 4 are used to perform preliminary positioning of the raw material. At the same time, the raw material passes between adjacent positioning plates 12, which can correct the direction of the raw material and limit the raw material between the positioning plates 12. Subsequently, the first telescopic rod 1 is started to control the longitudinal movement of the inner pressure plate 6, so that the inner pressure plate 6 enters the mold cavity 3 and performs compression molding on the raw material, thereby obtaining a finished processed back cover 9.
[0026] As a further embodiment of the present application, a plurality of fixing screw holes 10 are provided on the limit rod 11, and a limiting slide rod 13 is fixed on the connecting frame 8, and the limiting slide rod 13 and the limit rod 11 are slidably connected, and a plurality of corresponding grooves are provided on the connecting frame 8 for fixing the limit rod 11 and the connecting frame 8 under the action of bolts, maintaining the stability of the movement of the limit rod 11 under the action of the limiting slide rod 13, and adjusting the distance between adjacent positioning plates 12 by utilizing the combined action of the fixing screw holes 10 and the corresponding grooves, so as to realize the clamping function of raw materials of different sizes.
[0027] Since the position of the positioning plate 12 needs to be manually adjusted multiple times by using the bolts, fixing screw holes 10 and corresponding grooves, as a further embodiment of the present application, the present application slidingly connects the limit rod 11 and the limit slide bar 13, and at the same time fixes an adjustment slide bar 15 on the limit rod 11, and installs the adjustment slide bar 15 on the output end of the adjustment cylinder 14. The position of the adjustment slide bar 15 is controlled by the adjustment cylinder 14, thereby pushing the limit rod 11 to slide on the limit slide bar 13, so as to control the position of the positioning plate 12, so that the positioning plate 12 can be adapted to the shape of the raw material.
[0028] When the utility model is in use, the present application adopts automatic feeding, that is, the raw material passes through between the connecting frame 8 and the lower mold support 4. At this time, the raw material is in a relatively flat plate shape. After the initial limiting of the connecting frame 8 and the lower mold support 4, it smoothly enters below the inner pressure plate 6 and above the lower mold support 4, and then the feeding end of the raw material is cut off so that the raw material can be flattened, and the first telescopic rod 1 is used to start and control the inner pressure plate 6 to move longitudinally, so that the inner pressure plate 6 enters the mold cavity 3, and the raw material is molded, so that the finished product rear cover 9 can be obtained; then the adjustment motor 5 is used to drive the lower mold support 4 to rotate, so that the lower mold support 4 deviates from the upper mold support 2, so as to facilitate the unloading of the finished product rear cover 9;
[0029] In the above technical scheme, the position of the internal positioning component 7 can be adjusted in a variety of ways, that is, under the action of bolts, the limit rod 11 and the connecting frame 8 are fixedly connected, and the stability of the movement of the limit rod 11 is maintained under the action of the limit slide bar 13, and the distance between adjacent positioning plates 12 is adjusted by the combined action of the fixing screw hole 10 and the corresponding groove, so as to realize the clamping function of raw materials of different sizes; or the adjustment slide bar 15 is installed at the output end of the adjustment cylinder 14, and the position of the adjustment slide bar 15 is controlled by the adjustment cylinder 14, thereby pushing the limit rod 11 to slide on the limit slide bar 13, so as to control the position of the positioning plate 12, so that the positioning plate 12 can adapt to the shape of the raw material.
[0030] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
