When installing the lower mold 1141, the electric push rod drives the two sets of movable blocks 1151 to move, and the movable blocks 1151 drive the two sets of insertion rods 115 to move. When the insertion rods 115 are inserted into the sockets at both ends of the installation block 114, the lower mold 1141 can be installed easily. When the lower mold 1141 needs to be disassembled, the insertion rods 115 are separated from the sockets, so that the lower mold 1141 can be separated and used.

[0029] Exemplarily, four groups of support rods 110 are symmetrically fixedly connected to the upper surface of the base 100, and the tops of the four groups of support rods 110 are fixedly connected to a connecting plate 112. A cylinder 119 is fixedly installed on the lower surface of the connecting plate 112. The output end of the cylinder 119 is movably connected to a lifting rod 1191. The bottom end of the lifting rod 1191 is fixedly connected to a lifting plate 116. A mounting plate 117 is movably mounted on the lower surface of the lifting plate 116. The lower surface of the mounting plate 117 is fixedly connected to an upper mold 1171. The cylinder 119 cooperates with the lifting rod 1191 to drive the lifting plate 116 to descend, thereby facilitating the cooperation with the mounting plate 117 to drive the upper mold 1171 to descend for use.

[0030] Exemplarily, the lower surfaces of both ends of the lifting plate 116 are fixedly connected with a pulling plate 1183, and a fixing rod 118 is movably sleeved on one side surface of the pulling plate 1183. Fixing holes matching the fixing rod 118 are opened at both ends of the mounting plate 117. By inserting the fixing rod 118 into the fixing holes at both ends of the mounting plate 117, the upper mold 1171 can be easily installed and used. The fixing rod 118 is pulled by the pulling plate 1183 to separate the fixing rod 118 from the fixing hole, thereby facilitating the disassembly of the upper mold 1171.

[0031] Illustratively, a connecting block 1182 is fixedly connected to the lower surface of the lifting plate 116 , and the fixing rod 118 is movably sleeved on the connecting block 1182 . The setting of the connecting block 1182 facilitates the use of limiting the fixing rod 118 .

[0032] For some examples, see Figure 3 and Figure 4 The end of the pull plate 1183 away from the fixed rod 118 is fixedly connected with a handle 1184, and the surface of the side of the pull plate 1183 away from the handle 1184 is fixedly connected with a spring 1181 sleeved on the outer wall of the fixed rod 118. The spring 1181 is fixedly sleeved on the outer wall of the fixed rod 118. When the upper mold 1171 needs to be installed, the fixed rod 118 is pulled by the handle 1184. When the upper mold 1171 is in contact with the lower surface of the lifting plate 116, the handle 1184 is released. Under the action of the spring 1181, it is easy to drive the fixed rod 118 to reset. The fixed rod 118 is inserted into the fixing hole, and the upper mold 1171 can be installed and used.

[0033] For some examples, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The one side surface of the four groups of support rods 110 are fixedly connected to the limiting blocks 111, and the front and rear surfaces of the lifting plate 116 are symmetrically fixed with two groups of sliders 1161 that match the limiting blocks 111. The lifting plate 116 can be limited by the mutual cooperation between the sliders 1161 and the limiting blocks 111.

[0034] For some examples, see Figure 3 、 Figure 4 、 Figure 5 The lower surface of the connecting plate 112 is movably connected to a support assembly 120, and the support assembly 120 includes a threaded rod 121. The top of the threaded rod 121 is connected to a motor 1211 fixedly installed on the lower surface of the connecting plate 112 through a coupling. A sliding rod 122 is provided on one side of the threaded rod 121. The threaded rod 121 and the outer wall of the sliding rod 122 are movably connected with a movable plate 123. The motor 1211 can drive the threaded rod 121 to rotate, thereby facilitating the movable plate 123 to be raised and lowered, and the movable plate 123 can be limited by the sliding rod 122.

[0035] Illustratively, the movable plate 123 is threadedly connected to the threaded rod 121 , and support plates 124 are movably provided at both ends of the movable plate 123 , and the support plates 124 can be driven to be raised or lowered by the movable plate 123 .

[0036] For some examples, see Figure 3 、 Figure 4 、 Figure 5 The surface of the movable plate 123 is provided with a slot 1231, and the slot 1231 is movably sleeved on the outer wall of the lifting rod 1191. The setting of the slot 1231 facilitates the movement of the lifting rod 1191;

[0037] Exemplarily, both ends of the movable plate 123 are fixedly connected with a connecting shaft 1233, and one side surface of the end of the support plate 124 is fixedly connected with two groups of sleeves 1242 that are movably sleeved with the connecting shaft 1233. The arrangement of the sleeves 1242 and the connecting shaft 1233 facilitates the rotation of the support plate 124.

[0038] For some examples, see Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 , a fixing block 1232 is fixedly installed at both ends of the slot 1231 on the upper surface of the movable plate 123, a first magnet is fixedly installed on one side surface of the fixing block 1232, and a second magnet matching the first magnet is fixedly installed on one end of the support plate 124, and the support plate 124 is conveniently limited by the mutual cooperation of the first magnet and the second magnet;

[0039] Exemplarily, a second magnetic block 1241 is fixedly installed on one side surface of the support plate 124, and two groups of first magnetic blocks 1121 that are attracted to the second magnetic block 1241 are symmetrically fixedly connected to the lower surface of the slide rod 122. The mutual cooperation between the first magnetic block 1121 and the second magnetic block 1241 can fix the support plate 124 on the lower surface of the connecting plate 112.

[0040] For some examples, see Figure 4A positioning rod is fixedly connected to the upper surface of the support plate 124, and a positioning hole 1172 matching the positioning rod is opened on the lower surface of the upper mold 1171. The mutual cooperation between the positioning rod and the positioning hole 1172 facilitates the positioning of the upper mold 1171.

[0041] The working principle of the present invention is as follows: when the lower mold 1141 needs to be installed, the installation block 114 is placed on the upper surface of the fixed plate 113, the electric push rod is started, and the movable block 1151 is driven to move by the electric push rod, and the insertion rod 115 on the movable block 1151 is inserted into the jacks at both ends of the installation block 114, so that the lower mold 1141 can be installed and used;

[0042] Furthermore, when the upper mold 1171 needs to be installed and used, the upper mold 1171 is placed on the upper surfaces of the two sets of support plates 124, and the positioning holes 1172 on the upper mold 1171 are brought into contact with the positioning rods on the upper surfaces of the support plates 124, thereby facilitating the positioning of the upper mold 1171.

[0043] Furthermore, by starting the motor 1211, the motor 1211 drives the threaded rod 121 to rotate, and the threaded rod 121 can drive the movable plate 123 to be raised and lowered. At the same time, the movable plate 123 is limited by the slide bar 122, and the two sets of support plates 124 can be driven to move upward by the movable plate 123, so that it is convenient to drive the upper mold 1171 to move upward through the support plate 124. During the movement, the two sets of handles 1184 are pulled, and the handles 1184 pull the fixed rod 118. When the upper mold 1171 contacts the lower surface of the lifting plate 116, By loosening the fixing rod 118, the fixing rod 118 is reset under the action of the spring 1181, so that the fixing rod 118 is inserted into the fixing holes at both ends of the mounting plate 117, and the upper mold 1171 can be installed. Then, the threaded rod 121 cooperates with the movable plate 123 to drive the support plate 124 to descend. By rotating the two sets of support plates 124, the first magnet and the second magnet are attracted to each other, and then the support plate 124 is driven to rise by the movable plate 123, so that the first magnetic block 1121 and the second magnetic block 1241 are attracted to each other, thereby facilitating the fixing of the support plate 124.

[0044] Secondly, when the upper mold 1171 needs to be disassembled, the support plate 124 is driven downward by the movable plate 123. At this time, the first magnetic block 1121 and the second magnetic block 1241 are separated. Then, the support plate 124 is rotated to separate the first magnet from the second magnet. The support plate 124 is rotated to the bottom of the upper mold 1171. The upper mold 1171 is supported by the support plate 124, and the fixing rod 118 is separated from the fixing hole, thereby facilitating the disassembly and use of the upper mold 1171.

[0045] When the lower mold 1141 needs to be disassembled, the electric push rod cooperates with the movable block 1151 to drive the two sets of insertion rods 115 to separate from the socket, thereby facilitating the release of the limit on the lower mold 1141 and the disassembly of the lower mold 1141. The operation is simple and easy to use, making it easy to quickly install and disassemble the lower mold 1141 and the upper mold 1171, thereby improving work efficiency and reducing the workload of staff.
