Multiple runners connected to the glue inlet hole are arranged in the runner plate. Each runner is provided with multiple branch runners, and multiple branch runners are provided with multiple glue outlets. The multiple glue outlets are opposite to the multiple mold holes on the upper mold plate. The molten rubber flows into the mold through the glue inlet hole for curing. After demolding, the vulcanization is completed. When disassembling or replacing the mold, the entire mold needs to be installed, disassembled or replaced together, which is troublesome. And because the glue inlet hole must be accurately aligned, it often needs to be corrected several times during the assembly of the upper mold before the installation is completed. The installation process is time-consuming and labor-intensive, which affects work efficiency.

Figure 5 It is a schematic structural diagram of the first embodiment of the utility model after the vulcanization mold is clamped.

[0027] The utility model provides a clamping device, comprising a plurality of long bolts 101 and a mounting plate 102. The above-mentioned solution solves the technical problem that when clamping vulcanization molds of different sizes, the two connecting blocks 109 on the first screw need to be rotated in sequence, and since it is impossible to ensure that the moving distances of the two connecting blocks 109 are the same, it is easy to cause misalignment between the mounting plate 102 and the vulcanization mold.

[0028] According to the present specific embodiment, the middle part of the mounting plate 102 has a first glue inlet hole 103 and two rotating grooves 104, the first glue inlet hole 103 is provided with a gate sleeve 105, the gate sleeve 105 has a main flow channel 106, the rotating groove 104 is provided with a rotating sleeve 107, the rotating sleeve 107 is provided with a bidirectional screw 108, and the bidirectional screw 108 passes through both sides of the mounting plate 102, both ends of the bidirectional screw 108 are threadedly provided with a connecting block 109, the lower part of the connecting block 109 is provided with a supporting member 110, both sides of the connecting block 109 are provided with a slider 111, and the slider 111 is provided with a supporting member 110. A sliding rod 112 is provided, which is fixedly connected to the mounting plate 102 and is located on the outer side of the mounting plate 102. The four bottom corners of the mounting plate 102 are provided with U-shaped grooves 121. The plurality of long bolts 101 are respectively arranged in the corresponding U-shaped grooves 121. The bidirectional screw 108 is enabled to rotate by the rotating sleeve 107. The two connecting blocks 109 are horizontally moved and simultaneously moved under the action of the sliding rod 112 and the slider 111, thereby ensuring that the moving distances of the two connecting blocks 109 are consistent, thereby avoiding misalignment between the mounting plate 102 and the vulcanization mold.

[0029] A limiting block 113 is disposed at one end of the slide bar 112 away from the mounting plate 102 , and the limiting block 113 can prevent the slider 111 from moving out of the slide bar 112 .

[0030] Secondly, a plurality of anti-skid protrusions 114 are disposed on the outer side of the rotating sleeve 107 , and the anti-skid protrusions 114 can increase the friction force on the rotating sleeve 107 , thereby facilitating better rotation of the rotating sleeve 107 .

[0031] When the utility model is used to clamp the vulcanization mold, the rotating sleeve 107 is rotated to make the rotating sleeve 107 drive the bidirectional screw 108 to rotate, and the two connecting blocks 109 are simultaneously moved horizontally by the bidirectional screw 108 and the sliding rod 112, and are adjusted to a size suitable for the flow channel plate 115. At this time, the flow channel plate 115 is placed between the two connecting blocks 109, and the rotating sleeve 107 is rotated in the opposite direction to make the abutting pieces 110 under the two connecting blocks 109 abut against the flow channel plate 115. Finally, the upper mold plate 116, The middle template 117, the lower template 118 and the bottom plate 119 are penetrated and connected to the bottom of the vulcanizing equipment 120 by a plurality of the long bolts 101, and the first glue inlet hole 103 is connected to the glue outlet hole of the vulcanizing equipment 120, thereby completing the clamping of the vulcanizing mold. In this way, the technical problem that when clamping vulcanizing molds of different sizes, the two connecting blocks 109 on the first screw need to be rotated in sequence, and since it is impossible to ensure that the moving distances of the two connecting blocks 109 are the same, it is easy to cause misalignment between the mounting plate 102 and the vulcanizing mold.
