DETAILED DESCRIPTION

[0027] The present invention is further described below in conjunction with the embodiments, which are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in the field without creative work are all within the protection scope of the present invention.

[0028] See also Figure 1-Figure 4 As shown, this embodiment discloses a foaming mold frame, specifically a foaming identification error-proofing system, comprising a support frame 101, a placement table 102, an error-proofing component and a mold frame structure, wherein the support frame 101 is used to be placed on the ground; the placement table 102 is installed on the support frame 101, and the placement table 102 is used to carry a foaming mold 103; the error-proofing component is arranged on the foaming mold 103, and the error-proofing component is used to prevent the foaming mold 103 from being misaligned when the mold is closed; the mold frame structure is used to be installed on the support frame 101 and the placement table 102;

[0029] Among them, the mold frame structure includes a crank frame 104, a connecting rod 105, a clamping frame 106, a bracket 107 and a telescopic assembly 108. The telescopic assembly 108 is arranged on the placement table 102. The crank frame 104 is hinged on the placement table 102. The lower end of the crank frame 104 is hinged to the movable end of the telescopic assembly 108. There are two connecting rods 105. The upper ends of the two connecting rods 105 are hinged to the upper end of the crank frame 104, and the lower ends of the two connecting rods 105 are hinged to the clamping frame 106. The bracket 107 is fixedly arranged on the support frame 101, and the clamping frame 106 is hinged to the bracket 107.

[0030] The utility model mainly includes a support frame 101, a placement table 102, an error-proofing component and a mold frame structure. In actual use, the staff installs the lower end of the foaming mold 103 on the placement table 102, and installs the upper end of the foaming mold 103 on the pressing frame 106. At this time, the staff controls the telescopic component 108 to shrink. When the telescopic component 108 shrinks, the lower end of the crank frame 104 is pulled to move toward the telescopic component 108. Since the crank frame 104 rotates around the placement table 102, , the upper end of the crank frame 104 moves away from the telescopic component 108, and at the same time, the angle between the connecting rod 105 and the crank frame 104 gradually decreases, thereby driving the upper end of the foaming mold 103 to rotate. When the crank frame 104 and the connecting rod 105 are collinear, due to the dead point principle of the crank-connecting rod 105 mechanism, when the crank frame 104 and the connecting rod 105 are collinear, the crank-connecting rod 105 mechanism cannot continue to move and is locked. In this way, the tension of the telescopic component 108 allows the clamping frame 106 to push the upper end of the foaming mold 103 The end is tightly pressed against the lower end of the foaming mold 103; at this time, the staff injects the raw material to be foamed into the foaming mold 103, and the foaming mold 103 is heated by itself, and the foaming mold 103 is foamed inside. During the foaming process, the inside of the foaming mold 103 expands. Therefore, it is necessary to shrink the telescopic component 108 and press the clamping frame 106 to ensure that the foaming mold 103 will not be expanded; when the foaming of the foaming mold 103 is completed, the foaming parts are taken out. At this time, it is necessary to control the expansion of the telescopic component 108. The telescopic component 108 is long and controls the crank frame 104 to rotate after being extended. After the crank frame 104 rotates, it pulls the connecting rod 105 to rotate, and the connecting rod 105 opens the upper end of the foaming mold 103 to complete the opening of the foaming mold 103. The advantage of this arrangement is that the dead point principle of the crank connecting rod 105 mechanism is used to ensure the stability of the foaming of the foaming mold 103 when the foaming mold 103 is closed, and the opening and closing of the foaming mold 103 are achieved by only one telescopic component 108, so the use cost and production cost are relatively low.

[0031] In some embodiments, the crank frame 104 includes a first crank 110, a second crank 111, a first round rod 112 and a second round rod 113. The first crank 110 and the second crank 111 are respectively hinged on both sides of the placement table 102, the first round rod 112 and the second round rod 113 are arranged between the first crank 110 and the second crank 111, the first round rod 112 is located at the upper end of the first crank 110 and the second crank 111, the second round rod 113 is located at the lower end of the first crank 110 and the second crank 111, the movable end of the telescopic assembly 108 is hinged to the second round rod 113, and the connecting rod 105 is hinged to the first round rod 112.

[0032] In actual use, the first crank 110 and the second crank 111 are of V-shaped structure. After the first round rod 112 is hinged to the telescopic assembly 108, the telescopic assembly 108 contracts to pull the first crank 110 and the second crank 111 as a whole.

[0033] In some embodiments, a third round rod 114 is disposed at one end of the connecting rod 105 away from the second round rod 113 , the third round rod 114 is connected to the pressing frame 106 , and the two connecting rods 105 are hinged to the third round rod 114 .

[0034] In actual use, the third round rod 114 is provided to facilitate installation of the two connecting rods 105 and the pressing frame 106 .

[0035] In some embodiments, a hinge portion 115 is disposed at the movable end of the telescopic assembly 108 , and the hinge portion 115 is hinged to the second round rod 113 .

[0036] In actual use, the purpose of providing the hinge portion 115 is to facilitate the hinge connection between the telescopic assembly 108 and the second round rod 113 .

[0037] In some embodiments, a stopper 116 is disposed on the connecting rod 105 , and the stopper 116 is used to contact the crank frame 104 and to limit the crank frame 104 .

[0038] In actual use, the purpose of setting the stopper 116 is to make the crank frame 104 and the connecting rod 105 collinear to form a dead point, so as to prevent the telescopic assembly 108 from damaging the crank frame 104 and the connecting rod 105 by excessive force.

[0039] In some embodiments, a hard rubber pad 117 is disposed on the placement table 102 , and the foaming mold 103 is used to be installed on the hard rubber pad 117 .

[0040] In actual use, the purpose of providing the hard rubber pad 117 is to prevent the foaming mold 103 from having hard contact with the placement table 102 during installation.

[0041] In some embodiments, the foaming mold 103 includes an upper mold 118 and a lower mold 119. The upper mold 118 is installed below the clamping frame 106, and the lower mold 119 is installed on the hard rubber pad 117. Damping telescopic rods 120 are arranged on both sides of the upper mold 118 and the lower mold 119. One end of the damping telescopic rod 120 is hinged to the upper mold 118, and the other end is hinged to the lower mold 119.

[0042] During actual use, when the clamping frame 106 opens the upper mold 118, the upper mold 118 rises together with the clamping frame 106. At this time, the damping telescopic rod 120 extends, and the two ends of the damping telescopic rod 120 rotate around the upper mold 118 and the lower mold 119 respectively, thereby achieving the purpose of opening the mold. When closing the mold, the clamping frame 106 drives the upper mold 118 to descend. At this time, the damping telescopic rod 120 contracts, and the two ends of the damping telescopic rod 120 rotate around the upper mold 118 and the lower mold 119 respectively, thereby achieving the purpose of closing the mold. The advantage of this arrangement is that the speed of opening and closing the mold can be controlled by the component telescopic rod, making the opening and closing of the mold more stable.
