[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments, such as "inside", "outside", "left", "right" and similar expressions are only for the purpose of explanation and are not intended to limit the present invention.

[0024] Please refer to Figures 1 to 6 , is a schematic diagram of a casing trimming and shaping device 100 of the utility model, which is installed on a hydraulic press when in use. The casing trimming and shaping device 100 comprises an upper mold mechanism 20 and a lower mold mechanism 30 arranged vertically opposite to each other, and the upper mold mechanism 20 and the lower mold mechanism 30 can move relative to each other, thereby completing trimming and demoulding.

[0025] Furthermore, the upper mold mechanism 20 shown includes an upper mold base plate 21, a floating plate 22 floatingly connected to the upper mold base plate 21, an upper cutter module 23 installed on the bottom of the floating plate 22, and a guide column 24 installed on the bottom of the upper mold base plate 21. The upper cutter module 23 is provided with an upper cutting edge 25 and an upper shaping table 26 located on one side of the upper cutting edge 25. The lower mold mechanism 30 includes a lower mold base plate 31, a lower cutter module 32 installed on the lower mold base plate 31, and a guide sleeve 33 matched with the guide column 24. The lower cutter module 32 is provided with a lower cutting edge 34 and a lower shaping table 35 located on one side of the lower cutting edge 34. The lower cutting edge 34 is arranged opposite to the upper cutting edge 25, and the lower shaping table 35 is arranged opposite to the upper shaping table 26. Among them, the upper shaping table 26 is located outside the upper cutting edge 25, and the lower shaping table 35 is located outside the lower cutting edge 34. In this embodiment, the upper cutter module 23 is formed by splicing a plurality of upper cutter seats, and the lower cutter module 32 is formed by splicing a plurality of lower cutter seats, so that the installation and disassembly are more convenient and quick.

[0026] Furthermore, a first stop post 27 is installed on the bottom of the upper mold base plate 21, and a second stop post 36 is installed on the lower mold base plate 31, and the second stop post 36 is arranged opposite to the first stop post 27. In this embodiment, the first stop post 27 is symmetrically located on both sides of the guide post 24, and the second stop post 36 is symmetrically located on both sides of the guide post 24. By setting the first stop post 27 and the second stop post 36, the relative movement distance between the upper mold mechanism 20 and the lower mold mechanism 30 can be effectively limited to avoid damage to the knife caused by excessive movement. In this embodiment, a limit platform 241 is provided on the guide post 24, and the outer diameter of the limit platform 241 is larger than the inner diameter of the guide sleeve 33, so that the guide post 24 and the guide sleeve 33 not only have a guiding function, but also a limiting function.

[0027] Furthermore, the floating plate 22 is provided with an escape opening 221 , and an accommodating space is formed between the floating plate 22 and the upper mold base plate 21 through the escape opening 221 , thereby being able to accommodate a relatively high portion of the product to be trimmed.

[0028] Furthermore, the upper mold mechanism 20 also includes at least one group of floating support components 28 installed between the upper mold base plate 21 and the floating plate 22. In this embodiment, there are three groups of floating support components 28, and the three groups of floating support components 28 are arranged at equal intervals, so that the supporting force is balanced. The floating support component 28 includes a support seat 281 on the upper mold base plate 21, a floating rod 282 that is movably sleeved on the support seat 281 and connected to the floating plate 22, and a spring 283 sleeved on the floating rod 282. The two ends of the spring 283 are respectively in contact with the support seat 281 and the floating plate 22. The floating rod 282 and the spring 283 are multiple groups and are arranged along the length direction of the support seat 281. Furthermore, a spring accommodating groove (not shown) is provided on the support seat 28, and the spring 283 is at least partially located in the spring accommodating groove. By setting the spring accommodating groove, the stability of the installation of the spring 283 can be further guaranteed. The spring 283 is specifically a flat wire spring, so that the floating plate 22 can have a certain range of elastic movement when pressed down, thereby playing the role of pressing the product.

[0029] Furthermore, the floating support assembly 28 also includes two floating guide rods 285 and two floating guide sleeves 286 , wherein the floating guide sleeves 286 are installed on the support seat 281 , and the floating guide rods 285 pass through the floating guide sleeves 286 to be connected to the floating plate 22 .

[0030] Furthermore, the upper mold mechanism 20 further includes a plurality of first positioning seats 222 and a second positioning seat 223 mounted on the floating plate 22, and the lower mold mechanism 30 further includes a plurality of third positioning seats 311 and a fourth positioning seat 312 mounted on the lower mold base plate 31, the third positioning seat 311 is arranged opposite to the first positioning seat 222, and the fourth positioning seat 312 is arranged opposite to the second positioning seat 223. When in use, a clamping point is formed between the first positioning seat 222 and the third positioning seat 311, and a clamping point is formed between the second positioning seat 223 and the fourth positioning seat 312, thereby clamping and fixing the housing product.

[0031] Furthermore, the upper mold mechanism 20 further includes two first side blocks 224 mounted on the floating plate 22, and the lower mold mechanism 30 further includes two second side blocks 313 mounted on the lower mold base plate 31. The first side blocks 224 and the second side blocks 313 cooperate to form a side limit space, and the side edges of the housing product can be limited and supported by the first side blocks 224 and the second side blocks 313 to avoid loosening during trimming and shaping, thereby affecting the quality of the housing product after trimming and shaping. In this embodiment, the first positioning seat 222 and the second positioning seat 223 are located between the two first side blocks 224, and the third positioning seat 311 and the fourth positioning seat 312 are located between the two second side blocks 313.

[0032] Furthermore, the casing trimming and shaping device 100 also includes a locking strip 40, and both ends of the locking strip 40 are respectively connected to the upper mold mechanism 20 and the lower mold mechanism 30, so that the upper mold mechanism 20 and the lower mold mechanism 30 can be locked together when not in use.

[0033] When the above-mentioned casing trimming and shaping device 100 is used, the casing product 200 to be trimmed is placed on the lower mold mechanism 30, and then the upper mold mechanism 20 is pressed down by the drive of the hydraulic press, and then the casing product is sheared through the upper cutting edge 25 and the lower cutting edge 34, and the excess runner, flash, material cake, etc. are cut off. Since there is an upper shaping table 26 on one side of the upper cutting edge 25 and a lower shaping table 35 on one side of the lower cutting edge 34, the periphery of the trimming part of the casing product can be squeezed and shaped at the same time when in use. Therefore, through this structural setting, the two functions of trimming and correction shaping can be simultaneously possessed, which improves processing efficiency and reduces production costs. This solution can realize flatness correction while trimming, and the flatness requirement of 0.3mm is achieved, which is time-saving, efficient, and consistent, and greatly reduces the workload of grinding and manual correction.

[0034] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
