Description

Technical Field

[0001] The utility model relates to the technical field of pulp molding, in particular to a mold structure for solving the blockage of exhaust holes in deep-cavity colored pulp molding. Background Technique

[0002] Colored pulp molding products are rich and diverse in color and are deeply favored by customers. However, during the production process of colored pulp molding products, the exhaust holes are prone to blockage, especially for deep-cavity colored pulp molding products. The cavity is deep and there are many sidewall exhaust holes. After the air holes are blocked, the color of the product will be abnormal, resulting in quality problems. Therefore, regular maintenance is required, but the maintenance cycle is very short and troublesome. Since the mold core and the base are easily adhered together under high temperature and pressure, it is difficult to disassemble during maintenance. Content of the Utility Model

[0003] (1) Technical Problems to be Solved

[0004] In view of the deficiencies of the prior art, the utility model provides a mold structure for solving the blockage of exhaust holes in deep-cavity colored pulp molding, and solves the problems raised in the above background technique.

[0005] (2) Technical Solutions

[0006] To achieve the above purposes, the utility model is realized through the following technical solutions: A mold structure for solving the blockage of exhaust holes in deep-cavity colored pulp molding, including a hot pressing base and a hot pressing mold core. An installation groove is opened above the hot pressing base, and a gas guiding groove is opened below the hot pressing base. A base air hole, a countersunk head step hole and a disassembly hole penetrating the upper and lower surfaces are opened between the gas guiding groove and the installation groove. A positioning block is arranged on the bottom surface of the installation groove. Sidewall air holes are opened around the hot pressing mold core, and a mold core bottom hole is opened on the bottom surface of the hot pressing mold core. A positioning step is arranged around the lower part of the hot pressing mold core, and a positioning groove is arranged on the bottom surface of the hot pressing mold core.

[0007] Preferably, the positioning step is in clearance fit with the installation groove, and the height of the positioning step is the same as the depth of the installation groove, making the mating surface more beautiful after the hot pressing base and the hot pressing mold core are assembled.

[0008] Preferably, the positioning block is embedded in the positioning groove and has a small clearance fit. The number of the positioning blocks and the positioning grooves is three. Not only are their positions in one-to-one correspondence, but the distance between the three positions is relatively large, so that the hot pressing base and the hot pressing mold core have high repeat installation accuracy after being positioned by three pairs of positioning blocks and positioning grooves.

[0009] Preferably, the mold core bottom hole is perpendicular to the bottom surface of the hot pressing mold core, the mold core bottom hole is communicated with the sidewall air holes, and the upper and lower positions of the base air hole and the mold core bottom hole are in one-to-one correspondence to allow air to flow through, so that the base air hole is also communicated with the sidewall air holes.

[0010] Preferably, the air guide groove is communicated with all the base air holes. The width and depth dimensions of the air guide groove are relatively large, so that the volume of the air guide groove is large enough to accommodate more waste pulp powder, thereby extending the mold maintenance cycle.

[0011] Preferably, the hot pressing base and the hot pressing die core are locked by countersunk head screws passing through the countersunk head stepped holes. The number of disassembly holes is several and the distribution range is wide. The aperture size of the disassembly holes is relatively large, and a large enough ejector rod can pass through to facilitate the disassembly of the hot pressing base and the hot pressing die core.

[0012] The utility model provides a mold structure for solving the blockage of exhaust holes in deep-cavity colored pulp molding, and has the following beneficial effects:

[0013] 1. For the mold structure for solving the blockage of exhaust holes in deep-cavity colored pulp molding, through the setting of the air guide groove, the mold structure for solving the blockage of exhaust holes in deep-cavity colored pulp molding has the effect that the exhaust holes are not easily blocked. By connecting all the exhaust holes through the air guide groove to realize the shunt of compressed air, since the volume of the air guide groove is large, even if the air flow rate is very high, it is not easy to appear a low-pressure area, so that all the exhaust holes can evenly discharge high-speed air flow, thereby realizing the effect that the exhaust holes are not easily blocked.

[0014] 2. For the mold structure for solving the blockage of exhaust holes in deep-cavity colored pulp molding, through the setting of the air guide groove, the mold structure for solving the blockage of exhaust holes in deep-cavity colored pulp molding has the effect of a long maintenance cycle and thus reduces trouble. Since the increased volume of the air guide groove can accommodate more waste pulp powder, the exhaust holes can maintain uniform exhaust without being interfered by waste pulp powder for a long time. Therefore, the maintenance cycle can be long and the trouble caused by frequent mold disassembly can be reduced.

[0015] 3. For the mold structure for solving the blockage of exhaust holes in deep-cavity colored pulp molding, through the setting of the disassembly holes, the mold structure for solving the blockage of exhaust holes in deep-cavity colored pulp molding has the effect of facilitating the disassembly of the die core and the base. Since the number of disassembly holes is large, the distribution is wide and the inner diameter is large, it is possible to apply a greater force to push open the die core from multiple positions to achieve the effect of facilitating the disassembly of the die core and the base.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a mold structure for solving the blockage of exhaust holes in deep cavity colored pulp molding, including a hot pressing base 1 and a hot pressing die core 2. An installation groove 101 is opened above the hot pressing base 1, and an air guide groove 102 is opened below the hot pressing base 1. A base air hole 103, a countersunk head step hole 104, and a disassembly hole 105 that penetrate the upper and lower surfaces are opened between the air guide groove 102 and the installation groove 101. A positioning block 106 is provided on the bottom surface of the installation groove 101. The air guide groove 102 is communicated with all the base air holes 103. The width dimension and depth dimension of the air guide groove 102 are relatively large, so that the volume of the air guide groove 102 is large enough to accommodate more waste pulp powder, thereby extending the mold maintenance cycle. Side wall air holes 201 are opened around the hot pressing die core 2, and a die core bottom hole 202 is opened on the bottom surface of the hot pressing die core 2. A positioning step 203 is provided around the lower part of the hot pressing die core 2, and a positioning groove 204 is provided on the bottom surface of the hot pressing die core 2. The positioning step 203 is in clearance fit with the installation groove 101, and the height of the positioning step 203 is the same as the depth of the installation groove 101, so that the mating surface is more beautiful after the hot pressing base 1 and the hot pressing die core 2 are assembled. The positioning block 106 is embedded in the positioning groove 204 with a small clearance fit. The number of the positioning blocks 106 and the positioning grooves 204 is three. Not only are their positions in one-to-one correspondence, but the distance between the three positions is relatively large, so that the hot pressing base 1 and the hot pressing die core 2 have high repeat installation accuracy after being positioned by three pairs of positioning blocks 106 and positioning grooves 204. The die core bottom hole 202 is perpendicular to the bottom surface of the hot pressing die core 2, and the die core bottom hole 202 is communicated with the side wall air holes 201. The upper and lower positions of the base air holes 103 and the die core bottom holes 202 are in one-to-one correspondence to allow air to flow, so that the base air holes 103 are also communicated with the side wall air holes 201. The hot pressing base 1 and the hot pressing die core 2 are locked by countersunk head screws passing through the countersunk head step holes 104. The number of the disassembly holes 105 is several and the distribution range is wide. The aperture size of the disassembly holes 105 is relatively large, and a large enough ejector rod can pass through to facilitate the disassembly of the hot pressing base 1 and the hot pressing die core 2.

[0023] During use, first machine the outer contour of the hot pressing die core 2, and further machine the installation groove 101 and the positioning block 106 of the hot pressing base 1. Further, install the hot pressing die core 2 into the installation groove 101 through the positioning of the positioning block 106 and the positioning groove 204. If the hot pressing base 1 and the hot pressing die core 2 cannot rotate relative to each other at this time, it indicates that the positioning block 106 has achieved the positioning effect. If there is shaking, machine the hot pressing base 1 again or fill the original positioning groove 204 and then machine it with a reduced size. It is required that the repeated assembly accuracy of the hot pressing die core 2 and the hot pressing base 1 be high. Further machine the countersunk head stepped hole 104 and drill the corresponding threaded hole. Further, lock the hot pressing die core 2 and the hot pressing base 1 into a whole with countersunk head screws, and drill the base air hole 103 and the die core bottom hole 202 from the bottom surface of the hot pressing base 1 upwards. Further, disassemble the hot pressing die core 2 and the hot pressing base 1. Further, evenly open the side wall air holes 201 from the side according to the position of the die core bottom hole 202. Further, machine the air guide groove 102 connecting all the base air holes 103 and the disassembly hole 105 on the bottom surface of the hot pressing base 1. The air guide groove 102 is 20 mm wide and 5 mm deep, which is larger than the traditional size. The inner diameter of the disassembly hole 105 is 12 mm, which is larger than the traditional size. Since the volume of the air guide groove 102 is large, even if the air flow rate is very high, it is not easy to form a low-pressure area, so that all the exhaust holes can evenly discharge high-speed air flow. Since the increased volume of the air guide groove 102 can accommodate more waste pulp powder, the exhaust holes can be kept evenly exhausting without being interfered by waste pulp powder for a long time. Since the number of disassembly holes 105 is large and distributed widely and the inner diameter is large, a greater force can be applied from multiple positions to push open the die core.

[0024] In summary, the mold structure for solving the blockage of the exhaust holes of the deep-cavity colored pulp molding realizes the shunt of compressed air through the air guide groove 102 connecting all the exhaust holes. Since the volume of the air guide groove 102 is large, even if the air flow rate is very high, it is not easy to form a low-pressure area, so that all the exhaust holes can evenly discharge high-speed air flow, thus achieving the effect that the exhaust holes are not easily blocked. Since the increased volume of the air guide groove 102 can accommodate more waste pulp powder, the exhaust holes can be kept evenly exhausting without being interfered by waste pulp powder for a long time. Therefore, the maintenance period can be extended and the trouble caused by frequent disassembly of the mold can be reduced. Since the number of disassembly holes 105 is large and distributed widely and the inner diameter is large, a greater force can be applied from multiple positions to push open the die core to achieve the effect that the die core and the base are easy to disassemble.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
