Description

Technical Field

[0001] The invention relates to the technical field of hair dryer injection moulds, in particular to an air concentrating nozzle forming mould for hair dryer processing which is easy to cool. Background Art

[0002] In the processing of hair dryers, the nozzle forming mold is of great importance, and its performance has a profound impact on product quality and production efficiency. Traditional nozzle forming mold cooling methods mostly rely on water cooling systems, which are full of drawbacks. The water cooling system has a complicated architecture, and matters such as pipeline laying, the purchase of coolant circulation devices, and sealing maintenance all require high investments and frequent manpower intervention, resulting in soaring production costs and difficult equipment operation and maintenance. Pipelines are prone to scaling, corrosion, and blockage, which causes coolant flow obstruction, a sharp drop in heat exchange efficiency, and an imbalance in mold temperature, resulting in uneven cooling of the nozzle, shrinkage deformation, cracks and other quality defects, an increase in the defective rate, and serious waste of materials and working hours. The mold processing cycle is extended due to the lengthy cooling process, which is difficult to meet the demand for efficient production, and the company's market responsiveness and competitiveness have suffered a heavy blow.

[0003] In addition, the traditional mold injection molding process has many loopholes. In the raw material filling stage, the pressure and flow control are often inaccurate, resulting in missing or excessive filling of the mold cavity, uneven wall thickness of the product, incomplete structure, and loss of mechanical and appearance quality. The mold opening and closing action is mechanical, and the switching between the injection molding and cooling processes is rigid. There is a high degree of dependence on manual operation, a low degree of automation, frequent interruptions in production continuity, low efficiency and high labor costs. Furthermore, the flow characteristics of the raw materials inside the mold are poor, and stagnant areas are easily formed, resulting in uneven distribution of raw materials, insufficient fusion, large fluctuations in product performance, poor consistency, and failure to meet high-quality production needs.

The air collecting nozzle forming mold for hair dryer processing which is easy to cool can continuously discharge the hot air on both sides of the outer mold tube and the inner mold tube to the outside through the first air vent and the second air vent which are arranged in a staggered manner, thereby completing the cooling work after injection molding. Compared with the commonly used water cooling, it is not only more cost-effective, but also can avoid the subsequent maintenance problems caused by water channel blockage, thereby greatly improving the working stability and working life of the mold. When the top cover moves up, the electromagnetic plate is disconnected from the power supply and loses the adsorption of the pull rod, and the first working plate and the second working plate are reset. Because the first air vent and the second air vent are arranged in a staggered manner, when the first working plate and the second working plate are reset, the installation cavity is in a closed state, that is, the outer mold tube and the inner mold tube are effectively insulated during injection molding, thereby avoiding the problem of product defects of the air collecting nozzle after the injection molding due to unstable temperature of the outer mold tube and the inner mold tube during injection molding.

[0020] 2. The air concentrating nozzle forming mold for the hair dryer processing which is easy to cool injects raw materials into the mold cavity through the alignment groove under high pressure, thereby realizing integrated injection molding and automatically realizing the addition and injection of molten raw materials, greatly improving the degree of automation and production efficiency. The molten raw materials have been pressurized when injected through the alignment groove, that is, the molten raw materials can be quickly released to fill the mold cavity during injection molding, greatly increasing the filling amount in the mold cavity, that is, avoiding product quality problems caused by filling vacancies in the mold cavity during injection molding of existing injection molds.

[0021] 3. In the air collecting nozzle forming mold for hair dryer processing which is easy to cool, when the limit cover and the extrusion cover are separated from each other, the alignment groove is not immediately misaligned, that is, in addition to extracting the molten raw material through the input hole, a suction force is also generated on the internal cavity of the moving tube through the alignment groove, that is, the internal cavity of the moving tube is automatically cleaned to avoid the blockage of the moving tube and the injection molding quality problems, and when the limit cover and the extrusion cover are close to each other and merged, the internal cavity thereof is also connected with the outside through the mounting tube, thereby releasing the excess gas in the cavity to the outside through the cavity between the mounting tube and the threaded tube under negative pressure, avoiding the air extracted through the alignment groove from being stopped for a long time. The molten raw material in the inner cavity of the limit cover and the extrusion cover is stirred, which greatly improves the injection molding quality of the molten raw material, avoids the accumulation of molten raw material in the inner cavity of the limit cover and the extrusion cover, and causes injection molding quality problems, and also greatly improves the working stability of the mold.

[0044] During operation, when the air collecting nozzle needs to be injection molded, the upper mold assembly 5 can be pulled up along the slide bar 2 through the hydraulic system, so that the extrusion cover 55 can be pushed downward away from the limiting cover 54 under the action of elastic force. When the upper mold assembly 5 moves to the specified position, the limiting cover 54 and the extrusion cover 55 are fully expanded. At this time, the cavity between the limiting cover 54 and the extrusion cover 55 is in a negative pressure state as the limiting cover 54 and the extrusion cover 55 expand. That is, the molten raw material is extracted into the internal cavity through the input hole 53. After the raw material extraction is completed, the top cover 51 is driven down again by the hydraulic system, so that the extrusion cover 55 gradually contacts with the base 41, and the injection hole 56 is aligned and connected with the mold cavity between the outer mold tube 43 and the inner mold tube 44. As the top cover 51 continues to move downward, the limiting cover 54 and the extrusion cover 55 are fully expanded. The cover 54 and the extrusion cover 55 begin to shrink relatively, so that the pressure of the internal cavity increases, that is, the molten raw material is injected into the mold cavity through the injection hole 56 to complete the filling of the mold cavity. When the top cover 51 and the base 41 are completely aligned, the molten raw material filling is completed. At this time, the reciprocating hydraulic rod pulls the drive frame 59 to move up and down. When the drive frame 59 moves up and down, it will pull the electromagnetic plate 57 up and down through the transfer rod 58. After the upper mold group 5 moves downward and the alignment is completed, the electromagnetic plate 57 is automatically energized to adsorb the pull rod 411, and then the first working plate 49 and the second working plate 410 at the bottom are pulled up and down by the pull rod 411.

The holes 412 and the second air holes 413 can continuously discharge the hot air on both sides of the outer mold tube 43 and the inner mold tube 44 to the outside, thereby completing the cooling work after injection molding. Compared with the commonly used water cooling, it is not only more cost-effective, but also can avoid the subsequent maintenance problems caused by water channel blockage, greatly improving the working stability and working life of the mold. When the top cover 51 moves up, the electromagnetic plate 57 is disconnected from the power supply and loses the adsorption of the pull rod 411, and the first working plate 49 and the second working plate 410 are reset. Because the first air holes 412 and the second air holes 413 are staggered, when the first working plate 49 and the second working plate 410 are reset, the installation cavity 42 is in a closed state, that is, the outer mold tube 43 and the inner mold tube 44 are effectively insulated during injection molding. , to avoid the problem of temperature instability of the outer mold tube 43 and the inner mold tube 44 during injection molding, which may cause defects in the air collecting nozzle after the injection molding is completed. At the same time, when the extrusion cover 55 is extruded, it will also drive the working tube 510 and the limiting cover 54 to produce relative displacement, and the moving tube 512 slidably connected inside the working tube 510 is fixedly connected to the limiting cover 54 through the connecting rod 514, so the moving tube 512 and the working tube 510 will be dislocated up and down through the linkage groove 513. When the extrusion cover 55 and the limiting cover 54 are completely squeezed and merged, the alignment groove 511 on the moving tube 512 is connected to the alignment groove 511 on the working tube 510. Therefore, when the top cover 51 moves up, the alignment groove 511 on the moving tube 512 and the alignment groove 511 on the working tube 510 are gradually dislocated.Until they are completely misaligned, that is, the cavity between the limiting cover 54 and the extrusion cover 55 is in a closed state. At this time, as the limiting cover 54 and the extrusion cover 55 continue to be misaligned, the internal cavity is in a negative pressure state and the molten raw material is automatically drawn into the internal cavity through the input hole 53. When the top cover 51 moves down, the internal cavity will be compressed, thereby causing the internal cavity pressure to gradually increase. Finally, the alignment groove 511 on the moving tube 512 continues to align with the alignment groove 511 on the working tube 510, that is, the raw material is injected into the mold cavity through the alignment groove 511 under high pressure, thereby realizing injection molding integration and automatic The addition and injection of molten raw materials are realized, the degree of automation is greatly improved, and the production efficiency is improved. The molten raw materials have been pressurized when injected through the alignment groove 511, that is, the molten raw materials are quickly released to fill the mold cavity during injection molding, and the filling amount in the mold cavity is greatly increased, that is, the product quality problem caused by the filling vacancies in the mold cavity of the existing injection mold during injection molding is avoided. When the limiting cover 54 and the extrusion cover 55 are separated from each other, the alignment groove 511 is not immediately misaligned, that is, in addition to extracting the molten raw materials through the input hole 53, the alignment groove 511 will also produce the internal cavity of the moving tube 512 A suction force is generated, that is, the internal cavity of the moving tube 512 is automatically cleaned to avoid the blockage of the moving tube 512 and the injection molding quality problem. When the limiting cover 54 and the extrusion cover 55 are close to each other and merged, the internal cavity thereof will also be connected with the outside through the mounting tube 515, so as to release the excess gas in the cavity to the outside through the cavity between the mounting tube 515 and the threaded tube 517 under the negative pressure state, so as to avoid the air extracted through the alignment groove 511 staying in the internal cavity of the limiting cover 54 and the extrusion cover 55 for a long time to affect the filling and injection of the molten raw material. When the threaded rod 518 moves upward along the threaded tube 517, the threaded rod 518 rotates, and the toggle wheel 519 at the bottom of the threaded rod 518 rotates, that is, the toggle wheel 519 is always in a rotating state while the limit cover 54 and the extrusion cover 55 reciprocate, thereby stirring the molten raw material in the internal cavity of the limit cover 54 and the extrusion cover 55, greatly improving the injection molding quality of the molten raw material, avoiding the accumulation of the molten raw material in the internal cavity of the limit cover 54 and the extrusion cover 55 to cause injection molding quality problems, and also greatly improving the working stability of the mold.
