An upper die fixture 105 is disposed on the top frame 101. A lower die fixture 106 is disposed on the moving frame 103

[0038] Specifically, the rear end of the top frame 101 of the present application is hinged to the rear end of the support frame 102. By unlocking the buckle structure 108 between the front end of the top frame 101 and the support block 107 at the front end of the support frame 102, the front end of the top frame 101 can be lifted upward, and an open operating port is formed between the front end of the top frame 101 and the front end of the support frame 102, and the upper mold fixture 105 and the lower mold fixture 106 and other auxiliary mechanisms are exposed. At this time, the upper mold fixture 105 and the lower mold fixture 106 are installed or replaced, and other auxiliary mechanisms can also be inspected. It can be understood that after the front end of the top frame 101 is pressed down, the front end of the top frame 101 contacts the support block 107 again and is supported by the support block 107. At this time, the buckle structure 108 is in a locked state, and the front end of the top frame 101 and the support block 107 are inseparable.

[0039] In one embodiment, if Figure 2 and Figure 3 As shown, the top frame 101 is provided with an upper die rear positioning reference block 1011, an upper die left positioning reference block 1012 and an upper die right positioning reference block 1013, the upper die right positioning reference block 1013 is provided with an insertion groove, the upper die left positioning reference block 1012 is provided with an insertion groove, and the upper die left positioning reference block 1012 is also provided with a positioning pin 1014, which can be a knob positioning pin 1014 or other type of positioning pin 1014. The upper mold fixture 105 includes a first plate 1051 and a second plate 1052, and a plurality of connecting rods 1053 are connected between the first plate 1051 and the second plate 1052. The left end of the first plate 1051 is located in the insertion groove of the left positioning reference block 1012 of the upper mold and is positioned by the positioning pin 1014. The first plate 1051 is provided with a through hole for inserting the positioning pin 1014. The rear end of the first plate 1051 abuts against the rear positioning reference block 1011 of the upper mold, and the right end of the first plate 1051 is provided with a positioning edge 1055, and the positioning edge 1055 is located in the insertion groove of the right positioning reference block 1013 of the upper mold.

[0040] Specifically, the positioning pin 1014 is separated from the first plate 1051, and the first plate 1051 can be pulled out from the corresponding insertion groove, and then the upper mold fixture 105 can be pulled out as a whole. It can be understood that the first plate 1051 is inserted into the corresponding insertion groove, the rear end of the first plate 1051 is abutted against the upper mold rear positioning reference block 1011, and then the positioning pin 1014 is inserted into the through hole on the first plate 1051, so that the first plate 1051 can be quickly positioned.

[0041] Specifically, a test pin may be installed on the second board 1052 and a signal docking module connected to an external device may be provided on the first board 1051 .

[0042] In one embodiment, if Figures 4 to 7As shown, the lower mold fixture 106 includes a third plate 1062 and a fourth plate 1063, a plurality of connecting columns 1065 are arranged between the third plate 1062 and the fourth plate 1063, a carrier plate 1061 is also arranged on the top surface of the third plate 1062, a lower mold left positioning reference block 1032, a lower mold rear positioning reference block 1031 and a lower mold auxiliary positioning reference block 1033 are arranged on the movable frame 103, an insertion groove is arranged on the lower mold left positioning reference block 1032, a positioning groove 1066 and a first clearance through hole 1067 are arranged on the fourth plate 1063, and a clearance through hole corresponding to the first clearance through hole 1067 is also arranged on the movable frame 103 The rear end of the fourth plate 1063 abuts against the rear positioning reference block 1031 of the lower mold, the left end of the fourth plate 1063 is located in the insertion groove on the left positioning reference block 1032 of the lower mold, and the lower mold auxiliary positioning reference block 1033 is located in the positioning groove 1066 of the fourth plate 1063. A positioning cylinder 1035 connected to the mobile frame 103 is provided below the mobile frame 103, and the positioning cylinder 1035 is connected to the positioning block 1034. One end of the positioning block 1034 extends out from the first yielding through hole 1067 of the fourth plate 1063 and is located above the fourth plate 1063. The positioning block 1034 is used to position the fourth plate 1063.

[0043] Specifically, the positioning cylinder 1035 is a rotating clamping cylinder, which drives the positioning block 1034 to rotate a certain angle and move linearly. When the positioning block 1034 is away from the fourth plate 1063 and rotates a certain angle, the fourth plate 1063 can be pulled out from the corresponding positioning groove 1066, thereby allowing the lower mold fixture 106 to be pulled out as a whole. When the fourth plate 1063 is reinserted into the corresponding positioning groove 1066, the positioning cylinder 1035 drives the positioning block 1034 to rotate a certain angle and move linearly, and the positioning block 1034 applies a thrust to the fourth plate 1063, so that the fourth plate 1063 is fixed. Thus, the lower mold fixture 106 is fixed.

[0044] Specifically, a test pin may also be provided on the carrier board 1061 , and a signal docking module connected to an external device may be provided on the fourth board 1063 .

[0045] In one embodiment, if Figure 1 As shown, on the basis of the above, it also includes a control valve and a knob switch arranged on the base frame 104, the control valve is connected to the positioning cylinder 1035, and the knob switch is connected to the control valve.

[0046] Specifically, by rotating the knob switch, the control valve can be operated, and then the operation of the positioning cylinder 1035 can be controlled by the control valve.

[0047] In one embodiment, ifFigure 3 and Figure 4 As shown in Figure 4 , a plurality of guide posts 1054 are provided on the lower end surface of the second plate 1052, and a plurality of guide sleeves 1064 for inserting the guide posts 1054 are provided on the carrier plate 1061. After the upper die fixture 105 and the lower die fixture 106 are pressed together, the guide posts 1054 are inserted into the corresponding guide sleeves 1064.

[0048] In one embodiment, as Figure 1 shown, a nitrogen gas telescopic rod 111 is provided between the rear end of the top frame 101 and the rear end of the support frame 102.

[0049] In one embodiment, as Figure 8 shown, the buckle structure 108 includes a first hook 1071 provided on the support block 107. The buckle structure 108 further includes a clamping plate 1082, a spring 1083 and a mounting seat 1081. The mounting seat 1081 is provided at the front end of the top frame 101. The clamping plate 1082 is hinged to the mounting seat 1081 through a shaft. A spring 1083 is provided between the clamping plate 1082 and the top frame 101. The upper end of the clamping plate 1082 is located outside the mounting seat 1081. A second hook 1084 for clamping with the first hook 1071 is provided at the lower end of the clamping plate 1082.

[0050] Specifically, by pressing the upper end of the clamping plate 1082, the second hook 1084 at the lower end of the clamping plate 1082 can be separated from the first hook 1071. The spring 1083 is used to urge the clamping plate 1082 to reset. When the top frame 101 is pressed down from the open state and the front end of the top frame 101 contacts the support block 107, the second hook 1084 of the clamping plate 1082 is clamped with the first hook 1071 on the support block 107.

[0051] 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.
