[0021] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific implementation manners of the present utility model with reference to the accompanying drawings.

[0022] As Figure 1 shown, an embodiment of the present application provides a split mold clamping device, including a base body 1, a pressure plate 2, and an oil cylinder 3. An accommodating groove 11 for accommodating the pressure plate 2 is provided on the base body 1. The pressure plate 2 is located in the accommodating groove 11 and is rotatably connected to the base body 1. A fixing groove 12 for accommodating one end of the oil cylinder 3 is provided at one end of the base body 1. The oil cylinder 3 is detachably connected to the base body 1 through two symmetrically arranged connecting components 13. The oil cylinder 3 is located below one end of the pressure plate 2.

[0023] As Figure 2 shown, the connecting component 13 includes a connecting rod 131, a first spring 132, and a bolt 133. The connecting rod 131 includes a first connecting part 001 and a second connecting part 002. The diameter of the first connecting part 001 is larger than that of the second connecting part 002. The first spring 132 is sleeved on the second connecting part 002. One end of the first spring 132 abuts against the first connecting part 001, and the other end of the first spring 132 abuts against the base body 1. The bolt 133 passes through the oil cylinder 3 and is fixedly matched with the first connecting part 001. The bolt 133 is used to fix the connecting rod 131 in the base body 1 and the oil cylinder 3.

[0024] Specifically, two first connection holes and two second connection holes are symmetrically arranged on the fixing part 14 at the top of the fixing groove 12 of the seat body 1 and the supporting part 15 at the bottom of the fixing groove 12 respectively. One end of the oil cylinder 3 is inserted into the fixing groove 12 of the seat body 1, so that the two third connection holes symmetrically arranged on the oil cylinder 3 correspond to the first connection hole and the second connection hole respectively. Then the connecting rod 131 passes through the first connection hole, the third connection hole and the second connection hole in sequence. The first connecting part 001 is located in the first connection hole and the third connection hole, and the second connecting part 002 is located in the third connection hole and the second connection hole. The first spring 132 is sleeved on the second connecting part 002 and is located in the third connection hole. One end of the spring abuts against the first connecting part 001, and the other end of the spring abuts against the supporting part 15. Finally, the first connecting part 001 is fixed by the bolt 133.

[0025] The middle part of the pressing plate 2 is rotatably connected to the seat body 1 through the rotating shaft 21. One end of the oil cylinder 3 is inserted into the fixing groove 12 of the seat body 1, and then the seat body 1 and the oil cylinder 3 are fixed by two connecting components 13. Among them, the setting of the first spring 132 can not only prevent the looseness between the oil cylinder 3 and the seat body 1, but also play a role of buffering and guiding the oil cylinder 3 during use.

[0026] In the above structure, the seat body 1 and the oil cylinder 3 are detachably connected by setting the connecting component 13 to realize the separate processing of the seat body 1 and the oil cylinder 3. The oil cylinder 3 part can be processed and tested in advance, and then stored in the warehouse after the test. Subsequently, according to the customer's needs, the seat body 1 and the pressing plate 2 parts are separately manufactured and processed, and then assembled with the oil cylinder 3. This split-type clamping die not only has a simple structure and is convenient and fast to assemble, but also greatly reduces the production cycle, saves time costs, and improves the versatility.

[0027] As Figure 2 shown, in one of the embodiments, a positioning groove 003 for positioning and cooperating with the bolt 133 is provided on the first connecting part 001 of the split-type clamping die. During use, when the oil cylinder 3 is stressed, the oil cylinder 3 drives the bolt 133 to slightly move along the positioning groove 003, and the first spring 132 plays a buffering force on the oil cylinder 3. This setting facilitates the slight movement of the oil cylinder 3 when it is stressed, so that the oil cylinder 3 freely fits into the fixing groove 12 of the seat body 1.

[0028] As Figure 3As shown, in one embodiment, the oil cylinder 3 of the split mold clamping device includes a fixed seat 31, a sleeve 32, a piston 33, and a second spring 34. A groove 311 for accommodating the sleeve 32 is provided in the fixed seat 31. The groove 311 is threadedly connected to the sleeve 32. The sleeve 32 is sleeved on the piston 33. The second spring 34 is sleeved on one end of the piston 33. One end of the second spring 34 abuts against the piston 33, and the other end of the second spring 34 abuts against one end of the sleeve 32 close to the pressing plate 2. An oil hole 35 for communicating with the sleeve 32 is provided at one end of the fixed seat 31 away from the seat body 1.

[0029] In actual use, hydraulic oil is added into the sleeve 32 through the oil hole 35. The piston 33 is pushed upward under the action of the oil pressure, giving an upward pressure to one end of the pressing plate 2, so that the other end of the pressing plate 2 presses down on the mold. When the pressure is relieved, the hydraulic oil flows out and the pressure on the piston 33 is lost. The piston 33 returns to the initial position under the action of the second spring 34 and squeezes out the hydraulic oil, and the pressing plate 2 returns to the initial state.

[0030] This setting facilitates driving the piston 33 to move up and down in the sleeve 32.

[0031] As Figures 1 - 3 shown, in one embodiment, two fixing parts 14 are symmetrically provided at the upper end of the fixing groove 12 of the seat body 1 of the split mold clamping device, and a supporting part 15 is provided at the lower end of the fixing groove 12 of the seat body 1. A notch 312 for positioning and cooperating with the supporting part 15 is provided at one end of the fixed seat 31 extending into the fixing groove 12. When one end of the fixed seat 31 extends into the fixing groove 12, the fixing part 14 is located above one end of the fixed seat 31, and the end corner of the fixing part 14 is located above the sleeve 32.

[0032] Specifically, the fixing part 14 is a square fixing block, and the supporting part 15 is a rectangular step. When one end of the fixed seat 31 of the oil cylinder 3 extends into the fixing groove 12, the notch 312 part of the fixed seat 31 contacts the supporting part 15, and the connecting component 13 sequentially passes through the fixing part 14, the oil cylinder 3, and the supporting part 15 to fix the seat body 1 and the oil cylinder 3. After fixing, the fixing part 14 is not only located above the fixed seat 31, but also the end corner of the fixing part 14 is located above the sleeve 32. The setting of the notch 312 of the fixed seat 31 facilitates positioning and cooperation with the supporting part 15 to overcome dimensional errors. When stressed, the rest of the fixed seat 31 fits flatly with the tabletop and the force is evenly distributed. The setting of the end corner of the fixing part 14 facilitates fixing the sleeve 32 in the fixed seat 31 to prevent loosening after long-term use.

[0033] As Figure 1As shown, in one embodiment, a handle 313 is provided at one end of the fixed seat 31 of the split clamping die holder away from the seat body 1. This setting facilitates the staff to pull the handle 313 for operations such as disassembly, assembly, and movement of the oil cylinder 3.

[0034] As Figure 1 As shown, in one embodiment, the pressure plate 2 of the split clamping die holder is connected to the seat body 1 through a rotating shaft 21. One end of the pressure plate 2 is a pressing end 22, and the other end of the pressure plate 2 is a clamping end 23. The pressing end 22 is used to cooperate with the movement of the oil cylinder 3. This setting facilitates the oil cylinder 3 to drive the pressing end 22 of the pressure plate 2 to rotate, so that the clamping end 23 of the pressure plate 2 clamps or releases the die.

[0035] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
