DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0028] Embodiment 1:

[0029] A four-column hydraulic press with a protective structure for processing electrical equipment comprises a support leg 1, a hydraulic structure is installed on the top of the support leg 1, a mold disassembly structure is installed on the bottom of the hydraulic structure, and an ejection structure is installed on the bottom of the mold disassembly structure.

[0030] The hydraulic structure includes a body unit and a mold unit. The mold unit includes a connecting rod 106. An upper mold 107 is installed at the bottom of the connecting rod 106. Slides 108 are installed on the left and right sides of the upper mold 107. A slide column 109 is installed at the bottom of the slide column 108. A spring 110 is installed at the bottom of the slide column 108. An abutment plate 111 is installed at the bottom of the slide column 109. The body unit includes a workbench 101. Support frames 102 are installed at the left and right ends of the top surface of the workbench 101. A hydraulic component 103 is installed in the middle of the top surface of the support frame 102. A slide plate 104 is fixedly connected to the output end of the hydraulic component 103. Sliding holes are opened on the top surface of the slide plate 104 near the left and right ends. Positioning columns 105 are slidably connected to the inner walls of the sliding holes.

[0031] The top of the connecting rod 106 is fixedly connected to the middle of the bottom surface of the slide plate 104, the bottom surface of the workbench 101 is fixedly connected to the top of the supporting leg 1, the top of the positioning column 105 is fixedly connected to the bottom of the top of the support frame 102, the bottom end of the positioning column 105 is fixedly connected to the top surface of the workbench 101, and a round hole is opened in the middle of the bottom surface of the workbench 101.

[0032] Through the setting of the hydraulic structure, utilizing the sliding connection between the inner bottom end of the slide cylinder 108 and the outer surface of the slide column 109 and the installation of the spring 110, when the hydraulic component 103 is used to drive the slide plate 104 and the upper mold 107 for processing, the slide column 109 is slidably connected to the inner wall of the slide cylinder 108, and the spring 110 is compressed at the same time, thereby limiting it to prevent excessive descent and damage to the upper mold 107 and the lower mold 201.

[0033] When the hydraulic component 103 is used for hydraulic processing, the slide plate 104 is driven to descend by the hydraulic component 103, and the slide plate 104 drives the upper mold 107 to be hydraulically processed when it descends. During processing, the bottom surface of the abutment plate 111 abuts against the top surface of the lower mold 201, thereby making the outer surface of the slide column 109 slidably connected inside the slide cylinder 108. At the same time, the bottom end of the slide cylinder 108 and the top surface of the abutment plate 111 compress the spring 110, thereby limiting the upper mold 107 and the lower mold 201 during processing to prevent excessive displacement during the processing and damage to the mold.

[0034] Embodiment 2:

[0035] On the basis of the first embodiment, the mold disassembly and assembly structure includes a lower mold 201, a clamping block 202 is fixedly installed in the middle of the left and right sides of the lower mold 201, a clamping hole is opened on the top surface of the clamping block 202, a clamping rod 203 is connected inside the clamping hole, a stretching plate 204 is fixedly connected to the top of the clamping rod 203, and a spring 205 is installed and connected to the bottom surface of the stretching plate 204. The outer surface of the clamping block 202 is slidably connected to the inside of the slide groove opened on the front of the workbench 101, the end of the spring 205 away from the stretching plate 204 is fixedly connected to the top surface of the workbench 101, and the outer surface of the clamping rod 203 is slidably connected to the inner wall of the clamping hole 1 opened on the top surface of the workbench 101.

[0036] The ejection structure includes a mounting block 301, an asynchronous motor 302 is detachably mounted on the bottom surface of the mounting block 301, a cam 303 is connected to the output end of the asynchronous motor 302, a push plate 304 is connected to the outer surface of the cam 303, and a push rod 305 is fixedly mounted in the middle of the top surface of the push plate 304. The top surface of the mounting block 301 is fixedly connected to the bottom surface of the workbench 101, the outer surface of the push rod 305 is slidably connected to the inside of a circular hole in the middle of the bottom surface of the workbench 101, and the middle of the bottom surface of the push plate 304 is slidably connected to the outer surface of the cam 303.

[0037] By setting the ejection structure, the asynchronous motor 302 is used to drive the cam 303 to rotate, and the outer surface of the cam 303 is slidably connected to the bottom surface of the push plate 304, thereby driving the push plate 304 and the ejector rod 305 to slide up and down, thereby using the ejector rod 305 to eject the workpiece processed by the mold, which is convenient for material removal.

[0038] When the hydraulic part 103 is used to drive the upper mold 107 and the lower mold 201 to process the workpiece, the workpiece may be adhered to the lower mold 201 due to the hydraulic pressure. Therefore, after processing, the asynchronous motor 302 is started to drive the cam 303 to rotate. When the cam 303 rotates, it drives the push plate 304 to move up and down, thereby driving the ejector rod 305 to move up and down, and the workpiece can be ejected and taken out. When the lower mold 201 is disassembled and replaced after processing, the block 202 in the middle of the left and right sides of the lower mold 201 slides inside the slide groove opened on the front side of the workbench 101, and the clamping rod 203 is clamped inside the clamping hole opened on the top surface of the block 202. When replacing, the clamping plate 204 is pulled to drive the clamping rod 203 to move upward, so that the clamping rod 203 leaves the clamping block 202 and the clamping hole opened on the top surface of the workbench 101, thereby the lower mold 201 can be replaced.
