Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, specifically a liner alignment mold. Background Technology

[0002] Gaskets are sheet-like or plate-like parts that provide support, cushioning, sealing, and insulation. They are made of various materials, including metals, rubber, plastics, and composite materials. Their main functions are to fill gaps, distribute pressure, reduce vibration, or prevent leakage in fields such as mechanical assembly, construction, and electronics. The shape and specifications of gaskets are customized according to the application scenario, and they are characterized by simple structure, convenient installation, and strong adaptability.

[0003] When processing gaskets, metal, rubber, plastic, or composite materials are selected. They are produced in batches with regular shapes by stamping or molding. Metal or hard plastic gaskets are machined. Metal gaskets may be electroplated or painted to prevent rust. Rubber gaskets may be polished or coated to enhance wear resistance. The gaskets are then inspected after forming.

[0004] Warping and bending often occur during the stamping and cutting of gaskets, resulting in gaskets that do not meet the standards and need to be reworked. Therefore, a gasket straightening mold is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] Preferably, a pair of electric actuators are fixedly connected to the top of the first support frame; the electric actuators are positioned near the cylinder; a pressure plate is fixedly connected to the output end of the electric actuator; a round hole is opened at the top of the pressure plate; the cylinder is slidably connected to the round hole; by pushing the cylinder to move the pressure plate downward, the height deviation of the bolts can be judged, and all bolts can be reset to a uniform height, reducing the error in the shim alignment caused by the different bolt heights, and ensuring that each alignment can achieve the expected result.

By cooperating with the rotating handle, the surface of the pad is cleaned before it is placed in the lower mold, which can reduce contaminants on the surface of the pad, allowing the pad to enter the shaping process in a clean state, and reducing the local pressure and indentation caused by impurities.

[0009] Preferably, a heating plate is fixedly connected to the bottom end of the lower mold; the heating plate is correspondingly arranged with the upper mold; the heating function of the heating plate enables the pad to be heated synchronously when it is deformed under pressure, so as to evenly distribute the shaping pressure, increase the extensibility of the pad, and reduce the material rebound phenomenon.

By extracting the gas remaining in the middle of the upper and lower molds through the vacuum pump, the pad can be tightly fitted to the surfaces of the upper and lower molds, ensuring that the shaping pressure is evenly transmitted to each part, and further reducing the rebound caused by the completion of the shaping.

[0011] Preferably, a first sealing gasket is fixedly connected to the bottom end of the top plate; a second sealing gasket is fixedly connected to the top end of the worktable; the second sealing gasket is disposed on the side wall of the lower mold; the contact between the first sealing gasket and the second sealing gasket effectively reduces the gap between the upper mold and the lower mold from the inflow of external air, and in conjunction with the vacuum pump, maintains a stable vacuum environment, reduces the problem of insufficient vacuum caused by gas leakage, and increases the heating effect of the heating plate in the middle of the upper mold and the lower mold.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 5As shown in the embodiment of this utility model, a liner forming mold includes a workbench 1; a first support frame 11 is fixedly connected to the top of the workbench 1; a cylinder 12 is located at the top of the first support frame 11; a top plate 13 is fixedly connected to the output end of the cylinder 12; an upper mold 14 is fixedly connected to the bottom end of the top plate 13; multiple sets of bolts 15 are threadedly connected to the top of the top plate 13; the bolts 15 are evenly distributed on the top of the top plate 13; a pressure plate 16 is fixedly connected to the bottom end of the bolts 15; the pressure plate 16 is parallel to the bottom end of the upper mold 14; a lower mold 17 is fixedly connected to the top of the workbench 1; during operation, the liner to be formed is placed at the bottom of the lower mold 17. After the liner is properly positioned at the bottom of the lower mold 17, the position where the liner needs to be formed is checked. After confirming the position, a rotational force is applied to the bolt 15 directly above the position where the liner needs to be formed. When bolt 15 rotates, it causes the pressure plate 16 to protrude from the bottom of the upper mold 14 to a predetermined height. After adjusting bolt 15, cylinder 12 is pushed, causing the upper mold 14 to contact the lower mold 17, thus squeezing the pad inside the lower mold 17. The protruding part of the pressure plate 16 will continue to shape the pad. The lower mold 17 then pushes cylinder 12 again to raise the upper mold 14, thus completing the shaping of the pad in the middle of the lower mold 17. By applying rotational force to bolt 15 at a specific position, the height of the pressure plate 16 protruding from the bottom of the upper mold 14 can be flexibly controlled, allowing for precise shaping of the pad according to the deformation of different parts of the pad. This increases the precision of the pad shaping and reduces insufficient pressure when shaping a single mold. The pressure plate 16 is parallel to the bottom of the upper mold 14, reducing scratches, indentations, or damage to the pad surface caused by excessive local pressure during shaping.

[0025] like Figures 1 to 3 As shown, a pair of electric actuators 2 are fixedly connected to the top of the first support frame 11; the electric actuators 2 are positioned near the cylinder 12; a pressure plate 21 is fixedly connected to the output end of the electric actuators 2; a round hole 22 is opened at the top of the pressure plate 21; the cylinder 12 is slidably connected to the round hole 22; during operation, if multiple sets of bolts 15 are uneven after the lining is calibrated, the pair of cylinders 12 can be pushed to move the pressure plate 21 downwards. The pressure plate 21 stops when its bottom contacts the higher bolt 15. By checking the horizontal position between the pressure plate 21 and the bolt 15, the pressure plate 21 can be pushed upwards again to reset the uneven sets of bolts 15; by pushing the cylinder 12 to move the pressure plate 21 downwards, the height deviation of the bolts 15 can be judged, and all bolts 15 can be reset to a uniform height, reducing the error in lining calibration caused by the uneven height of the bolts 15, and ensuring that each calibration meets the expectations.

[0026] like Figures 4 to 5As shown, a pair of second support frames 3 are fixedly connected to the top of the workbench 1; a rotating seat 31 is fixedly connected to the side wall of the second support frame 3; a handle 32 is rotatably connected to the side wall of the rotating seat 31; a cleaning brush 33 is fixedly connected to the side wall of the second support frame 3; and a rotating wheel 34 is fixedly connected to the bottom of the workbench 1. During operation, after the pad is placed in the middle of the lower mold 17, the pad can be passed through the middle of the cleaning brush 33. A rotational force is applied to the handle 32 to move the pad in the middle of the cleaning brush 33. The cleaning brush 33 contacts the pad and removes contaminants from the surface of the pad. By cooperating with the rotating handle 32, the surface of the pad is cleaned before it is placed in the lower mold 17, which can reduce contaminants on the surface of the pad, allowing the pad to enter the shaping stage in a clean state and reducing the local pressure indentation caused by impurities.

[0027] like Figure 4 As shown, a heating plate 4 is fixedly connected to the bottom end of the lower mold 17; the heating plate 4 is correspondingly arranged with the upper mold 14; during operation, when the lower mold 17 and the upper mold 14 are shaping the pad, the heating plate 4 can be heated first. After the heating plate 4 is heated to a certain temperature, the upper mold 14 is pushed down into the lower mold 17. The lower mold 17 and the upper mold 14 press and cooperate with the heating plate 4 to further heat the pad during shaping; the heating function of the heating plate 4 enables the pad to be heated synchronously when it is deformed under pressure, evenly dispersing the shaping pressure, increasing the extensibility of the pad, and reducing the material rebound phenomenon.

[0028] like Figure 4 As shown, a vacuum pump 5 is fixedly connected to the top of the workbench 1; an extraction pipe 51 is fixedly connected to the side wall of the vacuum pump 5; the extraction pipe 51 is connected to the side wall of the upper mold 14; and an outlet 52 is fixedly connected to the side wall of the vacuum pump 5. During operation, when the upper mold 14 and the lower mold 17 are being calibrated, the vacuum pump 5 is activated to extract the gas in the middle of the lower mold 17 and the upper mold 14 from the extraction pipe 51 and discharge it from the outlet 52. By extracting the residual gas in the middle of the upper mold 14 and the lower mold 17 through the vacuum pump 5, the pad can be tightly attached to the surface of the upper mold 14 and the lower mold 17, ensuring that the calibration pressure is evenly transmitted to each part, and further reducing the rebound caused by the completion of calibration.

[0029] like Figure 1 and Figure 3As shown, a first sealing gasket 6 is fixedly connected to the bottom end of the top plate 13; a second sealing gasket 61 is fixedly connected to the top end of the worktable 1; the second sealing gasket 61 is disposed on the side wall of the lower mold 17; during operation, when the vacuum pump 5 extracts gas from the middle of the lower mold 17 and the upper mold 14, the lower mold 17 descends, causing the first sealing gasket 6 and the second sealing gasket 61 to come into contact, sealing the upper mold 14 and the lower mold 17 as a whole; through the contact between the first sealing gasket 6 and the second sealing gasket 61, the gap between the upper mold 14 and the lower mold 17 is effectively reduced, and in conjunction with the extraction of gas by the vacuum pump 5, a stable vacuum environment is maintained, reducing the problem of insufficient vacuum caused by gas leakage, and increasing the heating effect of the heating plate 4 in the middle of the upper mold 14 and the lower mold 17.

[0030] Working principle: The pad to be shaped is placed at the bottom of the lower mold 17. After the pad is properly positioned at the bottom of the lower mold 17, the position where the pad needs to be shaped is checked. Once the position is confirmed, a rotational force is applied to the bolt 15 directly above the position to be shaped. The bolt 15 rotates, causing the pressure plate 16 to protrude from the bottom of the upper mold 14 to a predetermined height. After adjusting the bolt 15, the cylinder 12 is pushed, causing the upper mold 14 to contact the lower mold 17, squeezing the pad inside the lower mold 17. The protruding part of the pressure plate 16 continues to shape the pad. The lower mold 17 is then pushed again, causing the cylinder 12 to lift the upper mold 14, thus completing the shaping of the pad in the middle of the lower mold 17. If multiple bolts 15 are uneven after shaping the pad, a pair of cylinders 12 can be pushed to move the pressure plate 21 downwards. The pressure plate 21 stops when its bottom contacts the higher bolt 15. By checking the horizontal position between the pressure plate 21 and the bolt 15, the pressure plate 21 can be pushed upwards again to flatten the uneven parts. After the bolt 15 is reset, and the gasket is placed in the middle of the lower mold 17, the gasket can be passed through the middle of the cleaning brush 33. A rotational force is applied to the handle 32, causing the gasket to move in the middle of the cleaning brush 33. The cleaning brush 33 contacts the gasket, removing contaminants from its surface. When the lower mold 17 and upper mold 14 are shaping the gasket, the heating plate 4 can be heated first. After the heating plate 4 reaches a certain temperature, the upper mold 14 is pushed down into the lower mold 17. The lower mold 17 and... The upper mold 14 presses and the heating plate 4 heats the gasket during the shaping process. When the upper mold 14 and the lower mold 17 are being shaped, the vacuum pump 5 is started to extract the gas in the middle of the lower mold 17 and the upper mold 14 from the exhaust pipe 51 and discharge it from the outlet 52. When the vacuum pump 5 extracts the gas in the middle of the lower mold 17 and the upper mold 14, the lower mold 17 descends so that the first sealing gasket 6 and the second sealing gasket 61 come into contact, sealing the upper mold 14 and the lower mold 17 as a whole.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
