Detailed implementation mode

[0023] The following is a description of the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not used to limit the present invention.

[0024] Embodiment: As Figure 1-4 shown, a device for measuring the internal airtightness of a mold according to the present invention includes a measuring bracket 1, on the inner wall of which a fixed mounting plate 3 for mounting the fixed mold 002 is installed. Fixed guide rods 15 are provided at the four top corners of the fixed mounting plate 3, and a moving mounting plate 9 for mounting the moving mold 001 is provided on one side of the fixed mounting plate 3; A measuring assembly 2 provided between the fixed mounting plate 3 and the moving mounting plate 9, the measuring assembly 2 includes a mounting frame 21, a double-sided test template 23 installed inside the mounting frame 21, and two symmetrically arranged L-shaped connecting pieces 25 at the top of the mounting frame 21. Connecting through holes 26 are provided on the L-shaped connecting pieces 25; A cooperating mechanism 6 for pushing the mounting frame 21 to reset it; A hanging mechanism 8 provided on one side of the L-shaped connecting piece 25, and the hanging mechanism 8 can be hooked on the upper fixed guide rod 15; A lifting mechanism 4 provided at the rear side of the measuring bracket 1 for driving the mounting frame 21 to lift; An auxiliary mechanism 7 provided at the top of the measuring assembly 2, which is composed of a lifting bracket 73, a control component for opening the hanging mechanism 8, and a connecting component. The lifting bracket 73 is fixedly connected to the moving body of the lifting mechanism 4 through a T-shaped connecting piece; An airtightness detector 5 provided on one side of the measuring bracket 1.

[0025] Specifically, the mold whose internal sealing needs to be detected is composed of a stationary mold 002 and a movable mold 001. After the molds are closed, the cavity on the stationary mold 002 and the movable mold together form a closed mold cavity that is consistent with the shape and size of the product.

[0026] As Figure 6-9 and Figure 11-12 shown, in the first embodiment: the suspension mechanism 8 includes a U-shaped connecting member 81 connected to an L-shaped connecting member 25, two suspension plates 85 mounted at the bottom of the L-shaped connecting member 25, an anti-disengagement hook 83 provided between the two suspension plates 85, and a rotating assembly for connecting the suspension plates 85 and the anti-disengagement hook 83. A U-shaped hanging hole is opened at the lower end of the suspension plate 85. The rotating assembly includes a first rotating shaft 82 or a second rotating shaft 89. The first rotating shaft 82 is rotatably connected to the suspension plate 85, and torsion springs 87 for connecting the first rotating shaft 82 and the suspension plate 85 are sleeved at both ends of the first rotating shaft 82. A sector gear 84 is also sleeved and fixed in the middle of the first rotating shaft 82.

[0027] The U-shaped bracket 74 drives the rack 78 to move downward, so that the rack 78 meshes with the sector gear 84 for transmission, causing the first rotating shaft 82 to rotate. The first rotating shaft 82 drives the anti-disengagement hook 83 to open. After the fixed guide rod 15 enters the sliding hole 86, the U-shaped bracket 74 drives the rack 78 to move upward, causing the anti-disengagement hook 83 to reset, so that the suspension mechanism 8 can be hooked on the fixed guide rod 15 and slide配合 with the fixed guide rod 15. When unlocking is required, the U-shaped bracket 74 drives the rack 78 to move downward, causing the anti-disengagement hook 83 to open, and then the lifting mechanism 4 is used to lift the mounting frame 21, so that the suspension mechanism 8 can be disengaged from the fixed guide rod 15. In this technical solution, through the cooperation of the suspension mechanism 8 and the control component, automatic unlocking of the suspension mechanism 8 can be achieved. When the suspension mechanism 8 is hooked on the fixed guide rod 15, it can be selected whether to be controlled by the control component. By being controlled by the control component, the opening angle of the anti-disengagement hook 83 can be controlled, which is more stable. If not controlled by the control component, energy can be saved.

[0028] As Fig. 9 shown, in the second embodiment: different from the first embodiment, the second rotating shaft 89 is rotatably connected to the suspension plate 85, and a torsion spring 88 for connecting the second rotating shaft 89 and the suspension plate 85 is sleeved in the middle of the second rotating shaft 89.

[0029] Rotate the anti-disengagement hook 83 by hand to open the anti-disengagement hook 83, and then use the lifting mechanism 4 to lift the mounting frame 21, so that the suspension mechanism 8 can be disengaged from the fixed guide rod 15. Compared with the first embodiment, the structure is simpler, and there is no need to set up a control component, so the manufacturing cost and use cost are lower, which is suitable for application in small measuring devices.

[0030] Among them, as Figure 7 and Figure 8 As shown, the anti - detachment hook 83 includes a support portion 831. Symmetrically arranged connecting arms 833 are provided at the top of the support portion 831. The connecting arms 833 are sleeved and fixed on the first rotating shaft 82 or the second rotating shaft 89. On one side of the bottom of the support portion 831, an anti - detachment hook 832 is provided. A sliding hole 86 that slidably cooperates with the fixed guide rod 15 is formed between the anti - detachment hook 832 and the U - shaped hanging hole. On one side of the anti - detachment hook 832, there is an inclined surface that can cooperate with the fixed guide rod 15.

[0031] During the downward movement of the installation frame 21, the inclined surface on the anti - detachment hook 832 first contacts the fixed guide rod 15. The anti - detachment hook 83 opens due to the pressing of the fixed guide rod 15, allowing the fixed guide rod 15 to enter the sliding hole 86. Then, driven by the elastic force of the first torsion spring 87 or the second torsion spring 88, the anti - detachment hook 83 resets, enabling the suspension mechanism 8 to be hooked on the fixed guide rod 15 and slidably cooperate with the fixed guide rod 15. The anti - detachment hook 83 is used to prevent the suspension mechanism 8 from detaching from the fixed guide rod 15 due to reasons such as晃动 (should be translated as "shaking" or other appropriate words).

[0032] Among them, as Figure 3 and Figure 5 shown, the control assembly includes a control cylinder 72 installed at the bottom of the top plate of the lifting bracket 73. The piston end of the control cylinder 72 is connected with a C - shaped bracket 74. Rack bars 78 that can mesh with the sector gear 84 are provided on both sides of the C - shaped bracket 74. By controlling the cylinder 72, the C - shaped bracket 74 can be driven to lift and lower. By driving the rack bar 78 through the C - shaped bracket 74, the rack bar 78 meshes with the sector gear 84 for transmission to control the opening angle of the anti - detachment hook 83.

[0033] Specifically, a limit through - hole is opened on the side plate of the lifting bracket 73, which slidably cooperates with the C - shaped bracket 74, playing a role in guiding and limiting.

[0034] Among them, as Figure 3 and Figure 5 shown, the connection assembly includes a driving motor 71 arranged inside the lifting bracket 73, a bidirectional lead screw 76 rotatably connected to the lifting bracket 73, and two L - shaped lifting members 75 arranged back - to - back. The output end of the driving motor 71 is in transmission connection with the bidirectional lead screw 76 through a transmission belt. The L - shaped lifting member 75 is fixed on the nut slider of the bidirectional lead screw 76. A connection plug rod 77 that is inserted into the connection through - hole 26 is also provided on the L - shaped lifting member 75.

[0035] After the driving motor 71 is started, the bidirectional lead screw 76 is driven by the transmission belt, so that the nut slide on the bidirectional lead screw 76 moves away from each other with the two L-shaped lifting members 75, and the position of the L-shaped lifting member 75 is adjusted. When it is necessary to lift the measuring component 2, the nut slide drives the L-shaped lifting member 75 to align the connecting rod 77 with the connecting through hole 26, and then the lifting mechanism 4 operates to move the lifting bracket 73 upward, thereby inserting the connecting rod 77 into the connecting through hole 26, and the measuring component 2 will move upward accordingly, completing the disassembly of the measuring component 2; When it is necessary to use the measuring component 2 to perform a sealing test on the movable mold 001 and the fixed mold 002, the measuring component 2 is controlled to move downward by the lifting mechanism 4. When the suspension mechanism 8 is hooked on the fixed guide rod 15, the installation of the measuring component 2 is completed. Thereafter, the lifting mechanism 4 continues to control the connection component to move downward, so that the connecting rod 77 is disengaged from the connecting through hole 26. Then, the drive motor 71 is started to make the nut slide on the bidirectional lead screw 76 bring the two L-shaped lifting members 75 closer to each other until the L-shaped lifting member 75 is no longer blocked by the L-shaped connecting member 25, and the connection component is driven upward by the lifting mechanism 4.

[0036] Among them, Figure 1 and Figure 2 As shown, guide holes that slide with the fixed guide rod 15 are provided at the four top corners of the movable mounting plate 9, a dustproof bin 11 is provided on one side of the movable mounting plate 9, a through hole is provided on the dustproof bin 11, and a driver 12 is also provided inside the dustproof bin 11, and the piston rod of the driver 12 is fixedly connected with the movable mounting plate 9 after passing through the through hole; the directionality of the movable mounting plate 9 during movement is improved by the sliding connection between the fixed guide rod 15 and the guide hole, and the movable mounting plate 9 is driven by the driver 12 to perform the mold closing operation.

[0037] Specifically, a sliding through hole slidably matched with the moving guide rod 61 is further provided at the lower part of the moving installation plate 9 , and the moving installation plate 9 can move smoothly through the provided sliding through hole.

[0038] Among them, Figure 2 and Figure 3 As shown, the matching mechanism 6 includes a movable guide rod 61 and a pushing cylinder arranged in the dustproof bin 11, one end of the movable guide rod 61 is installed with a pushing block 62, and the other end penetrates the dustproof bin 11 and extends to the inside of the dustproof bin 11 to be connected with the piston end of the pushing cylinder, the movable guide rod 61 is slidably matched with the dustproof bin 11, and a sliding block 22 is provided at the bottom of the mounting frame 21, and a U-shaped through hole slidably matched with the movable guide rod 61 is provided on the sliding block 22, and when the double-sided test template 23, the movable mold 001 and the fixed mold 002 are molded, the movable guide rod 61 plays a role in supporting the mounting frame 21, and the sliding cooperation with the movable guide rod 61 through the U-shaped through hole can also improve the directionality of the mounting frame 21 when moving; After the sealing performance detection is completed, the drive 12 drives the moving mounting plate 9 to move the moving die 001 back to the initial position. The pushing cylinder drives the moving guide rod 61 to move the pushing block 62, and the pushing block 62 pushes the mounting frame 21 to reset the mounting frame 21.

[0039] Among them, as Figure 1-4 shown, an inflation air path is provided in the double-sided test template 23. One side of the double-sided test template 23 is provided with a simulation cavity. A communication hole 24 communicating with the inflation air path is also communicated on one side of the simulation cavity. The air inlet of the inflation air path is connected to the inflation port of the airtightness detector 5 through a pipeline. One side of the double-sided test template 23 is a standard part one simulating the moving die 001 that matches the fixed die 002. The standard part one and the cavity of the fixed die 002 form a closed mold cavity. The other side of the double-sided test template 23 is a standard part two simulating the fixed die 002 that matches the moving die 001. The simulation cavity is arranged on the standard part two. The simulation cavity and the moving die 001 also form a closed mold cavity. Therefore, after the double-sided test template 23, the moving die 001 and the fixed die 002 are closed, the airtightness of the moving die 001 and the fixed die 002 can be detected respectively.

[0040] Specifically, the airtightness detector 5 generally includes a controller, a display screen, an air pump, and at least two independent inflation detection pipelines. The inflation detection pipeline includes a pressure detector for detecting air pressure. The air pump inflates the moving die 001 and the fixed die 002 through the two inflation detection pipelines respectively for airtightness detection. It should be noted that when performing airtightness detection, except for the ventilation holes connected to the inflation detection pipelines, other ventilation holes on the mold that can communicate with the outside need to be blocked.

[0041] Among them, as Figure 1 、 Figure 2 and Fig.10 shown, support brackets 13 are symmetrically arranged at the top of the bottom plate of the measuring bracket 1. A guiding slide rail 14 is arranged at the top of the support bracket 13. A horizontal chute 142 that slidably cooperates with the C-shaped connecting piece 81 is provided on the guiding slide rail 14. Two vertical chutes 141 that slidably cooperate with the C-shaped connecting piece 81 are communicated at the top of the horizontal chute 142. Through the sliding cooperation between the C-shaped connecting piece 81 and the vertical chute 141, the directivity of the up-and-down movement of the mounting frame 21 can be improved. Through the sliding cooperation between the C-shaped connecting piece 81 and the horizontal chute 142, the mounting frame 21 can be smoothly pushed by the moving mounting plate 9 towards the fixed mounting plate 3 to perform the mold closing operation of the double-sided test template 23, the moving die 001, and the fixed die 002.

[0042] During operation, the movable mold 001 and the fixed mold 002 are respectively mounted on the movable mounting plate 9 and the fixed mounting plate 3, and then connected to the airtightness detector 5 through a pipeline, and the movable mounting plate 9 is controlled to move by the driver 12, so that the movable mold 001 moves toward the direction close to the fixed mold 002. After the movable mold 001 and the fixed mold 002 are closed, the airtightness detector 5 is operated to inflate the closed mold cavity formed by the movable mold 001 and the fixed mold 002 for sealing detection. This process can be repeated for many times to reduce the probability of false detection. If the sealing test of the mold is qualified, the movable mold 001 and the fixed mold 002 can be removed; If the sealing test of the mold fails, the driver 12 controls the movable mold 001 to return to the initial position, and then the lifting mechanism 4 operates, and the lifting bracket 73 is driven downward by the lifting mechanism 4, thereby driving the installation frame 21 to move downward. In the process of the installation frame 21 moving downward, the inclined surface on the anti-detachment hook 832 first contacts the fixed guide rod 15, and the anti-detachment hook 83 is opened due to the pressure of the fixed guide rod 15, so that the fixed guide rod 15 enters the sliding hole 86, and then driven by the elastic force of the torsion spring 1 87 or the torsion spring 2 88, the anti-detachment hook 83 is reset, so that the hanging mechanism 8 is hooked on the fixed guide rod 15 and slidably cooperates with the fixed guide rod 15. In this process, the anti-detachment hook 83 can also be opened by the control component. When the hanging mechanism 8 is hooked on the fixed guide rod 15, the moving guide rod 61 enters The connecting member 001 is inserted into the U-shaped through hole, and then the lifting mechanism 4 continues to control the connection assembly to move downward, so that the connecting rod 77 is disengaged from the connecting through hole 26, and then the drive motor 71 is started, so that the nut slide on the bidirectional lead screw 76 brings the two L-shaped lifting members 75 closer to each other, until the L-shaped lifting members 75 are no longer blocked by the L-shaped connecting member 25, and the connection assembly is driven by the lifting mechanism 4 to move upward, and then the driver 12 controls the movement of the movable mounting plate 9 to move the movable mold 001 toward the direction close to the fixed mold 002, and the movable mold 001 pushes the mounting frame 21 to move toward the direction close to the fixed mold 002.
