Description

Technical Field

[0001] The present application relates to the technical field of injection molds, for example, to an injection molding component of an air conditioner outer cover. Background Art

[0002] At present, some small air conditioner outdoor units or some parts may be made of engineering plastics (such as ABS, PC, etc.) through injection molding. The cover of the air conditioner outdoor unit is generally made of engineering plastics by injection molding. Injection molding is to inject molten plastic into a pre-designed mold, and demold it after cooling to obtain a shell component with complex shape and precise size. In the injection molding process of the air conditioner outdoor unit cover, the molten plastic needs to enter the mold cavity. At this time, the air in the cavity needs to be exhausted in an instant, including the air in the cavity and the pouring system, the water vapor generated by the evaporation of the water contained in the plastic raw material at high temperature, the gas generated by the decomposition of the plastic at high temperature, and the gas generated by the volatilization or chemical reaction of certain additives in the plastic. In the injection molding process, poor exhaust will have the following effects on the air conditioner outdoor unit cover: ① Burning: The air in the cavity is compressed and immediately reaches a high temperature, and the part of the product that contacts the high-temperature air will produce local carbonization and burning. ② Insufficient filling: During the injection molding process, if the gas cannot be discharged in time, filling will be difficult. ③ Overflow: When the exhaust is insufficient, the injection pressure is usually increased, so that the force in the clamping direction will increase, which is easy to cause overflow. ④ Silver streaks and weld marks: The gas is not discharged smoothly, which makes the molten plastic enter the cavity at different speeds, which easily forms flow marks and weld marks. ⑤ Bubbles: Bubbles are generated due to poor exhaust, which is particularly obvious in transparent materials.

[0003] The related art provides a mold for injection molding of a central control panel of a sub-instrument panel with a spliced ​​exhaust insert, comprising a mold body, an injection molding cavity is provided on the mold body, and spliced ​​exhaust insert components are provided on the front and rear sides of the bottom of the injection molding cavity. Each spliced ​​exhaust insert component includes a plurality of sheet-like spliced ​​inserts and a pressing plate, a screw is installed in the middle of the pressing plate, and the plurality of sheet-like spliced ​​inserts are fixedly installed in the installation groove at the bottom of the injection molding cavity by the pressing plate and the screws. A hanging platform is provided at the lower end of a side surface of each sheet-like spliced ​​insert facing the pressing plate, and the sheet-like spliced ​​insert and the hanging platform form an L-shaped structure, and an extended pressing platform is provided at the upper end of a side surface of the pressing plate facing the sheet-like spliced ​​insert, and the pressing plate and the extended pressing platform form an inverted L-shaped structure, and the extended pressing platform is fitted on the upper surface of the hanging platform.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] Several sheet-like splicing inserts of the existing splicing exhaust insert are fixedly installed in the installation groove at the bottom of the injection cavity by means of a pressing plate and screws. The sheet-like splicing inserts are fixedly fixed by means of a screw on one side, which may cause the other side to warp due to excessive pressure on one side.

[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0041] Combination Figures 1 to 4 As shown, the embodiment of the present disclosure provides an air-conditioning outer cover injection molding component, and the air-conditioning outer cover injection molding component includes: a hanging platform 10 and an insert 20, the hanging platform 10 defines a mounting groove 101, the mounting groove 101 is used to install the insert 20, and the two sides of the mounting groove 101 are partially raised to form a first protrusion 11 and a second protrusion 12, and the first protrusion 11 is opposite to the second protrusion 12; the insert 20 is arranged in the mounting groove 101, and the insert 20 is constructed with a first recess 21 and a second recess 22, the first recess 21 is adapted to the first protrusion 11, and the second recess 22 is adapted to the second protrusion 12, so that the insert 20 is clamped with the hanging platform 10.

[0042] According to the disclosed embodiment, the hanging platform 10 and the insert 20 form a stable mechanical connection structure through the first protrusion 11 and the second protrusion 12, and the corresponding first recess 21 and the second recess 22. In this way, it can ensure that the hanging platform 10 and the insert 20 are tightly assembled and fixed without the need for additional fasteners (such as screws, rivets, etc.), and effectively prevent loosening or falling off due to vibration or impact. And compared with the method of fixing with screws, it can effectively avoid the problem that the pressure on one side is too large and the other side is tilted due to the unilateral locking of the insert 20 by screws. Secondly, the assembly steps of the insert 20 and the hanging platform 10 can be simplified, the complexity of manual operation is reduced, and the assembly efficiency is improved. In addition, through the first protrusion 11 and the second protrusion 12, and the corresponding first recess 21 and the second recess 22, the consistency and gap control between the hanging platform 10 and the insert 20 can be better maintained, which helps to improve the sealing performance of the overall structure. At the same time, the appearance is smooth, and there are no redundant fasteners exposed to the outside, which improves the aesthetics of the product.

[0043] Optionally, along the direction from the first protrusion 11 to the second protrusion 12 , the length dimension of the first protrusion 11 is less than one quarter of the length dimension of the insert 20 .

[0044] According to the embodiment of the present disclosure, the length dimension of the first protrusion 11 is set to be smaller than one quarter of the length dimension of the insert 20 along the direction from the first protrusion 11 to the second protrusion 12. In this way, the insert 20 can be more conveniently slid into the installation groove 101 from one side, and positioned and fixed by the first protrusion 11 on the opposite side, thereby reducing the difficulty of assembly and improving the assembly efficiency. Secondly, if the first protrusion 11 is too long, it may cause unnecessary interference or obstruction with the air guide groove 23 or other structures of the insert 20, affecting the overall structural layout and function realization of the insert 20. Shortening the first protrusion 11 can ensure that the various components do not interfere with each other and optimize space utilization.

[0045] Optionally, along the direction from the first protrusion 11 to the second protrusion 12 , the length dimension of the second protrusion 12 is less than one quarter of the length dimension of the insert 20 .

[0046] According to the embodiment of the present disclosure, the length dimension of the second protrusion 12 is set to be less than one quarter of the length dimension of the insert 20 along the direction from the first protrusion 11 toward the second protrusion 12. In this way, the insert 20 can be more conveniently slid into the installation groove 101 from one side, and positioned and fixed by the second protrusion 12 on the opposite side, thereby reducing the difficulty of assembly and improving the assembly efficiency. Secondly, if the second protrusion 12 is too long, it may cause unnecessary interference or obstruction with the air guide groove 23 or other structures of the insert 20, affecting the overall structural layout and function realization of the insert 20. Shortening the second protrusion 12 can ensure that the various components do not interfere with each other and optimize space utilization.

[0047] Preferably, the length of the first protruding portion 11 is equal to the length of the second protruding portion 12 .

[0048] In this way, by setting the length dimension of the first protrusion 11 equal to the length dimension of the second protrusion 12, the symmetry of the structure is ensured, which is not only more beautiful in visual effect, but also the first protrusion 11 and the second protrusion 12 have consistent restraining forces in two directions, which can provide balanced support and limiting effects, and is beneficial to the uniform distribution of force on both sides of the hanging platform 10, thereby enhancing the stability of the component.

[0049] Optionally, along the direction from the first protrusion 11 to the second protrusion 12 , the length dimension of the first recess 21 is smaller than the length dimension of the first protrusion 11 , and the length dimension of the second recess 22 is smaller than the length dimension of the second protrusion 12 .

[0050] With the embodiment of the present disclosure, the lengths of the first recess 21 and the second recess 22 are smaller than the corresponding protrusions, so that a certain gap can be reserved between the insert 20 and the wall of the mounting groove 101. This is not only conducive to positioning and insertion during the assembly process, but also ensures that the insert 20 will not be compressed and deformed due to insufficient expansion space during thermal expansion and contraction or slight deformation. Secondly, the reserved gap can make it more convenient for maintenance personnel to remove the insert 20, and the insert 20 can be easily removed for inspection, cleaning or replacement without additional tools. In addition, in the event of vibration or impact, the gap can create a certain buffer space between the insert 20 and the hanging platform 10, thereby avoiding damage caused by hard collision between the insert 20 and the hanging platform 10.

[0051] Optionally, when the insert 20 is engaged with the hanging platform 10 , the upper wall surface of the hanging platform 10 is flush with the upper wall surface of the insert 20 .

[0052] In this way, in the assembled state, the top plane of the insert 20 and the top plane of the hanging platform 10 fit each other without any height difference, which is beneficial to improving the surface flatness of the air conditioner outer unit cover after injection molding.

[0053] Optionally, the insert 20 is provided with an air guide groove 23 , and the wall surface of the hanging platform 10 abutting against the insert 20 is provided with an exhaust groove 13 , and the exhaust groove 13 is communicated with the air guide groove 23 .

[0054] According to the disclosed embodiment, by providing the air guide groove 23 on the insert 20, the air guide groove 23 can guide the airflow at the air-trapping position through the air guide groove 23, and by providing the exhaust groove 13 on the hanging platform 10 and connecting the exhaust groove 13 with the air guide groove 23, the air in the air guide groove 23 can flow into the exhaust groove 13 and flow out along the exhaust groove 13. In this way, injection defects (such as weld marks, bubbles, voids, etc.) caused by air entrapment can be avoided, and the surface quality and structural strength of the product can be improved.

[0055] Optionally, the hanging platform 10 is provided with an exhaust hole 14 , one end of the exhaust hole 14 is communicated with the exhaust groove 13 , and the other end of the exhaust hole 14 is communicated with the outside.

[0056] By adopting the embodiment of the present disclosure, by providing the exhaust hole 14 on the hanging platform 10 and connecting the exhaust hole 14 with the exhaust groove 13, the gas generated inside the insert 20 or during the injection molding process (such as the air in the molten plastic) can be smoothly guided out and discharged to the external environment. This can prevent the gas from being trapped inside the component to form defects such as bubbles and cavities, thereby improving the quality and durability of the product. The exhaust hole 14 helps to reduce pressure fluctuations during injection molding, ensure that the molten plastic evenly fills the mold cavity, reduce the scrap rate, and simplify the production process.

[0057] Optionally, there are multiple inserts 20 , and the multiple inserts 20 are arranged side by side along the extension direction of the installation groove 101 ; wherein the air guide groove 23 is located on the wall surface where adjacent inserts 20 abut against each other.

[0058] According to the embodiment of the present disclosure, by setting a plurality of inserts 20 and arranging the plurality of inserts 20 side by side along the extension direction of the mounting groove 101, the air guide groove 23 of each insert 20 is connected to the exhaust groove 13, and a plurality of exhaust channels 16 can be formed. In this way, the gas generated during the injection molding process can be dispersed through these exhaust channels 16 and discharged quickly, avoiding the problem of trapped air caused by excessive local pressure, thereby effectively preventing the formation of injection molding defects such as bubbles, weld marks, etc., and improving the quality and appearance of the product. Secondly, in the injection molding process, there is more than one trapped air position, and the trapped air position cannot be completely and accurately determined. By arranging a plurality of inserts 20 side by side, each insert 20 is provided with an air guide groove 23 and is connected to the exhaust groove 13, the number and distribution range of the exhaust positions can be significantly increased, thereby reducing the product defect rate caused by trapped air. In addition, the provision of a plurality of inserts 20 can also help optimize the filling flow state inside the mold, further improving the injection molding efficiency and product quality.

[0059] Optionally, the width of the air guide groove 23 is greater than the width of the exhaust groove 13 .

[0060] According to the embodiment of the present disclosure, by setting the width dimension of the air guide groove 23 larger than the width dimension of the exhaust groove 13, the larger air guide groove 23 is conducive to reducing the gas flow resistance, reducing the pressure loss of the gas from the trapped gas position to the exhaust groove 13, so that the gas can enter the exhaust groove 13 faster and easier. In this way, the gas generated during the injection molding process or the heat accumulated internally during operation can be more effectively guided to the exhaust groove 13 and finally discharged. Secondly, the wider air guide groove 23 can also play a certain role in preventing gas backflow, ensuring that the gas can flow stably to the exhaust groove 13, avoiding gas accumulation and product defects caused by poor exhaust. Moreover, since the air guide groove 23 is relatively wide, even if a small amount of impurities or melt enters the air guide groove 23, it is not easy to completely block the entire air guide groove 23, thereby ensuring the continuous effectiveness of the exhaust function.

[0061] Optionally, the thickness of the air guide groove 23 is 0.02 mm.

[0062] By adopting the embodiment of the present disclosure, by setting the thickness of the air guide groove 23 to 0.02 mm, the extremely thin air guide groove 23 can quickly and effectively discharge the gas generated during the injection molding process, avoiding the appearance of bubbles, cavities and other defects inside the product due to trapped gas, thereby improving the quality and appearance flatness of the product. Secondly, the possibility of molten plastic flowing into and clogging the air guide groove 23 can be greatly reduced, ensuring that the air guide groove 23 is always unobstructed during the injection molding process.

[0063] Specifically, the width of the air guide groove 23 is 15 mm.

[0064] In this way, the air guide groove 23 can be efficiently vented while avoiding being blocked, thereby effectively preventing bubbles from forming inside the molten plastic and improving the quality and appearance integrity of the product.

[0065] Optionally, the hanging platform 10 is provided with screw holes 15 so that the hanging platform 10 can be connected and fixed to other components by screws.

[0066] By adopting the embodiment of the present disclosure, by setting the screw hole 15 on the hanging platform 10, the hanging platform 10 can be connected with other components by screws. The screw connection method can provide a strong mechanical fixing effect, ensure that the connection between the hanging platform 10 and other structural parts is firm and reliable, and improve the stability and safety of the overall equipment. Secondly, screw connection is a standardized and highly versatile connection method, which is convenient for quick installation or replacement of parts during assembly and maintenance. Compared with some non-fastening connection methods (such as snap-fit, bonding, etc.), screw connection can withstand greater loads and impact forces, and is particularly suitable for connecting parts with larger load-bearing capacity to avoid the position displacement of the hanging platform 10 during the injection molding process.

[0067] Optionally, the screw hole 15 is located in the middle of the hanging platform 10 and close to the center of gravity of the hanging platform 10 .

[0068] In this way, by setting the screw hole 15 near the center of gravity of the hanging platform 10, the force between the entire hanging platform 10 and the connecting parts is more balanced, effectively preventing deformation or damage caused by uneven force. Secondly, it can better restrain the displacement of the hanging platform 10, and even when encountering large vibrations or load changes during the operation of the equipment, it can maintain a close fit between the hanging platform 10 and other components, thereby enhancing the stability and reliability of the overall equipment. In addition, when the hanging platform 10 needs to be disassembled, maintained or parts replaced, the screw hole 15 located at the center of gravity makes it easy for users to quickly find and tighten or loosen the screws, greatly improving work efficiency.

[0069] Optionally, the hanging platform 10 is provided with an exhaust channel 16, the exhaust channel 16 is arranged around the screw hole 15, the exhaust channel 16 is communicated with the exhaust groove 13, and the exhaust channel 16 is arc-shaped.

[0070] By adopting the embodiment of the present disclosure, by providing the exhaust channel 16 and connecting the exhaust channel 16 with the exhaust groove 13, the airflow in the exhaust groove 13 can flow out through the exhaust channel 16, which is conducive to the rapid filling and exhaust of the molten plastic during injection molding, thereby improving production efficiency and reducing the defective product rate. By setting the exhaust channel 16 around the screw hole 15 and setting the exhaust channel 16 in an arc shape, the arc-shaped exhaust channel 16 design cleverly isolates the heat source from the screw, reducing the risk of deformation or strength reduction of the screw due to heat. This not only ensures the stability of the screw connection, but also ensures that when the screw needs to be disassembled for maintenance, the screw will not be difficult to unscrew due to overheating, greatly improving the convenience of maintenance.

[0071] Specifically, combined Figure 3 As shown in , the center of the exhaust channel 16 coincides with the center of the screw hole 15 , and the center angle corresponding to the exhaust channel 16 is greater than 180 degrees and less than 270 degrees.

[0072] In this way, by aligning the center of the exhaust channel 16 with the center of the screw hole 15, and setting the center angle of the exhaust channel 16 to be greater than 180 degrees and less than 270 degrees, the exhaust channel 16 covers most of the space around the screw hole 15. Such a large-angle design ensures that the potential high-temperature area is more fully wrapped, thereby more effectively isolating the screw from contact with the heat source and enhancing the heat dissipation effect. And by setting the center angle to be less than 270 degrees, the integrity and strength of the structure of the hanging platform 10 can be guaranteed, and the situation of fracture at the connection between the screw and the hanging platform 10 can be avoided, ensuring that the bearing capacity or durability of the screw connection part will not be weakened due to the addition of the exhaust channel 16.
