Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and specifically provides a mold. Background Technology

[0002] As people's living standards improve, air conditioners have gradually become one of the indispensable household appliances in people's daily lives.

[0003] Household air conditioners have air deflectors at the air outlet to adjust the direction and angle of the airflow. Most existing air deflectors are made of plastic materials such as polyethylene, polypropylene, or acrylonitrile-butadiene-styrene copolymer, which are injected into a mold by an injection molding machine. The surface layer of the air deflector made of the above materials is good, but the strength is insufficient. During use or transportation, users may cause scratches or breakage to the air deflector.

[0004] In the current processing of air guide plates, glass fiber is added to the injection molding material. Glass fiber has the advantages of good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, which can improve the strength of the finished part. However, during the injection molding process, after the injection molding material with glass fiber is injected into the mold cavity, the injection material near the inner wall of the mold cavity will cool down and solidify rapidly before the glass fiber is fully wrapped. This will cause problems such as floating fibers on the surface of the molded air guide plate, which will seriously affect the surface effect of the air guide plate.

[0005] Therefore, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0046] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0047] It should be noted that in the description of this utility model, terms such as "inner" and "outer," which indicate direction or positional relationship, are based on the direction or positional relationship shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0048] Furthermore, it should be noted that in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connect," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0049] Based on the problem of fiber floating on the surface of existing air conditioning air guide plates containing glass fibers after casting, as pointed out in the background art, this utility model provides a mold. The purpose is to set a heating pipe in the inner wall of the mold cavity. When the casting material containing glass fibers is injected into the mold cavity, the heating pipe can heat the inner wall of the mold cavity, thereby prolonging the solidification time of the casting material near the inner wall of the mold cavity. This allows the casting material to fully mix and encapsulate the glass fibers, thus avoiding problems such as fiber floating on the surface of the shaped air guide plate.

[0050] Specifically, such as Figures 1 to 4 As shown, this utility model provides a mold for solidifying and shaping hot-melted casting material into a finished part. The mold has a mold cavity 5 and a gate 11 connected to the mold cavity 5. The casting material enters the mold cavity 5 through the gate 11. A heating pipe is provided in the inner wall of the mold cavity 5. The heating pipe can heat the casting material to prolong the solidification time of the casting material.

[0051] For example, such as Figures 1 to 4 As shown, the mold of this utility model is used in conjunction with an injection molding machine. The mold has a gate 11 and a mold cavity 5. Different shaped mold cavities 5 can be used to cast different plastic products. The injection molding machine injects molten polyethylene and other materials into the mold through the gate 11. After the mold cools, the injected material is also shaped, thus enabling the production of various plastic products. In order to enhance the strength of plastic products, existing processes also add glass fibers to the casting material to improve its strength. However, when the casting material containing glass fibers enters the mold cavity 5, the casting material near the inner wall of the mold cavity 5 cools rapidly. However, if the glass fibers in the casting material are not fully encapsulated by polyethylene and other materials before cooling and solidifying, problems such as loose fibers on the surface of the plastic product will occur, affecting the appearance quality of the finished product and posing safety hazards. Therefore, the mold of this utility model adds a heating pipe to the inner wall of the mold cavity 5. The heating pipe can heat the inner wall of the mold cavity 5, thereby extending the solidification time of the casting material near the inner wall of the mold cavity 5, so that the casting material can be fully mixed and encapsulated with glass fibers, thus avoiding problems such as loose fibers on the surface of the air guide plate after solidification.

[0052] Preferably, such as Figure 3 As shown, the mold of this utility model is used for casting air guide plates for air conditioners.

[0053] For example, such as Figure 3 As shown, the mold cavity 5 of this utility model is shaped like an air guide plate, and the casting material, after cooling and solidification, becomes an air guide plate for an air conditioner.

[0054] Preferably, such as Figures 1 to 4As shown, the mold of this utility model includes a fixed template 3 and a movable template 4 distributed at intervals along the vertical direction. The fixed template 3 is located above the movable template 4. The fixed template 3 has a fixed mold core 31, and the movable template 4 has a movable mold core 41. The fixed mold core 31 and the movable mold core 41 together form a mold cavity 5. The heating pipe includes a first heating pipe 91 and a second heating pipe 92. The first heating pipe 91 is located in the inner wall of the fixed mold core 31, and the second heating pipe 92 is located in the inner wall of the movable mold core 41.

[0055] For example, such as Figures 1 to 4 As shown, the fixed template 3 and the moving template 4 of this utility model are arranged opposite to each other, with the fixed template 3 located above the moving template 4. The fixed mold core 31 and the moving mold core 41 are also arranged opposite to each other, with the fixed mold core 31 located above the moving mold core 41. When the fixed template 3 and the moving template 4 are pressed together, the fixed mold core 31 and the moving mold core 41 are also tightly pressed together, thus forming a mold cavity 5. The fixed mold core 31 is provided with a first heating tube 91, and the moving mold core 41 is provided with a second heating tube 92. By passing hot oil (the temperature of the hot oil can reach 120°C) into the first heating tube 91 and the second heating tube 92, the hot oil can heat the inner wall of the mold cavity 5, thereby extending the solidification time of the casting material near the inner wall of the mold cavity 5, so that the casting material can be fully mixed and wrapped around the glass fiber.

[0056] It should be noted that this utility model does not limit the number or arrangement of the first heating tube 91 and the second heating tube 92. For example, those skilled in the art can set the first heating tube 91 and the second heating tube 92 as a single tube or multiple tubes, etc. Alternatively, the first heating tube 91 and the second heating tube 92 can be arranged linearly along the length of the mold cavity 5, or arranged in a curved and spaced manner, etc. Such adjustments and changes to the specific number and arrangement of the first heating tube 91 and the second heating tube 92 do not deviate from the principle and scope of this utility model, and should all be limited to the protection scope of this utility model.

[0057] Preferably, such as Figures 1 to 3 As shown, the present invention has multiple first heating tubes 91, which are distributed at intervals along the width direction of the mold cavity 5.

[0058] For example, such as Figures 1 to 3 As shown, the present invention has three first heating tubes 91, which are distributed at intervals along the width direction of the mold cavity 5 on the fixed mold core 31.

[0059] Preferably, such as Figures 1 to 3 As shown, the present invention has multiple second heating tubes 92, which are spaced apart along the width direction of the mold cavity 5.

[0060] For example, such as Figures 1 to 3As shown, the present invention has three second heating tubes 92, which are distributed at intervals along the width direction of the mold cavity 5 on the moving mold core 41.

[0061] like Figure 3 As shown, the three first heating tubes 91 are above the three second heating tubes 92.

[0062] Preferably, such as Figure 4 and Figure 5 As shown, the mold of this utility model also includes a runner pipe 21. One end of the runner pipe 21 is connected to the gate 11, and the other end of the runner pipe 21 is provided with an injection port 22, which is connected to the mold cavity 5.

[0063] For example, such as Figure 4 and Figure 5 As shown, the top end of the runner tube 21 of this utility model is provided with an inlet that communicates with the gate 11, and the bottom end of the runner tube 21 is provided with an injection port 22. The injection port 22 passes through the fixed template 3 and the fixed mold core 31 and communicates with the mold cavity 5. The injection molding machine injects the casting material into the mold cavity 5 through the runner tube 21.

[0064] It should be noted that the present invention does not limit the number of injection ports 22. For example, those skilled in the art can set the number of injection ports 22 to 1, 2 or more, etc. Such adjustments and changes to the specific number of injection ports 22 do not deviate from the principle and scope of the present invention and should be limited to the protection scope of the present invention.

[0065] Preferably, such as Figure 4 and Figure 5 As shown, the present invention has multiple injection ports 22, which are distributed at intervals along the length of the mold cavity 5.

[0066] For example, such as Figure 4 and Figure 5 As shown, the present invention has five injection ports 22, which are distributed at intervals along the length of the mold cavity 5 and are all connected to the mold cavity 5. This arrangement enables the casting material to be evenly distributed in the mold cavity 5, thereby improving the injection molding efficiency and effect.

[0067] Preferably, such as Figures 4 to 6 As shown, the mold of this utility model also includes a third heating tube 93, which covers the outer wall of the injection port 22 to heat the casting material flowing through the injection port 22.

[0068] For example, such as Figures 4 to 6As shown, the third heating tube 93 of this utility model is disposed inside the inner wall of the fixed mold core 31. The third heating tube 93 is provided with an annular channel 931, that is, the third heating tube 93 changes from a straight tube to an annular tube at the annular channel 931. The injection port 22 is inserted into the central hole of the annular tube. The annular channel 931 can tightly cover the injection port 22. The third heating tube 93 is provided with 5 annular channels 931 corresponding to 5 injection ports 22. When hot oil is introduced into the third heating tube 93, the third heating tube 93 can heat the injection ports 22, thereby increasing the temperature of the casting material during injection, prolonging the cooling time of the casting material, and improving the casting effect.

[0069] It should be noted that the third heating tube 93 of this utility model can also be configured to be wound around the outer wall of the injection port 22, etc. Such adjustments and changes to the specific setting position of the third heating tube 93 do not deviate from the principle and scope of this utility model, and should be limited to the protection scope of this utility model.

[0070] Preferably, such as Figure 4 , Figure 7 and Figure 8 As shown, the mold of this utility model also includes a lifting mechanism 6. The moving mold plate 4 is provided with an opening 42 that communicates with the mold cavity 5. The top end of the lifting mechanism 6 is inserted into the opening 42. The end faces of the fixed mold core 31, the moving mold core 41 and the top end of the lifting mechanism 6 enclose the mold cavity 5. The lifting mechanism 6 can separate the finished part from the mold cavity 5 after the casting material is shaped.

[0071] For example, such as Figure 4 , Figure 7 and Figure 8 As shown, the movable template 4 and movable mold core 41 of this utility model are provided with openings 42 that penetrate the movable template 4 and movable mold core 41 in a vertical direction. The top end of the lifting mechanism 6 is inserted into the opening 42. The end face of the top end of the lifting mechanism 6 and the inner wall of the movable mold core 41 form a smooth surface, which is the bottom surface of the finished part. The inner wall of the fixed mold core 31 is the top surface of the finished part. The end faces of the fixed mold core 31, the movable mold core 41 and the top end of the lifting mechanism 6 together form the mold cavity 5. After the mold is poured and the finished part is cooled and shaped, the injection molding machine separates the fixed template 3 from the movable template 4. The injection molding machine then drives the lifting mechanism 6 to move upward, thereby separating the finished part from the mold cavity 5, so that the finished part can be easily removed.

[0072] Preferably, such as Figure 4 , Figure 7 and Figure 8As shown, the lifting mechanism 6 of this utility model includes a lifting component 61 and a fixing component 62. The lifting component 61 is inserted into the opening 42. The top end face of the lifting component 61, together with the fixed mold core 31 and the moving mold core 41, forms a mold cavity 5. The bottom end of the lifting component 61 is fixedly connected to or integrally set with the fixing component 62. The fixing component 62 can move vertically relative to the moving mold plate 4.

[0073] For example, such as Figure 4 , Figure 7 and Figure 8 As shown, the lifting component 61 of this utility model includes a lifting part 611 and a supporting part 612. The lifting part 611 is rectangular and arranged in a horizontal direction. The top wall of the lifting part 611, together with the fixed mold core 31 and the moving mold core 41, forms a mold cavity 5. The supporting part 612 is arranged in a vertical direction. The top end of the supporting part 612 is integrally formed with the lifting part 611. The bottom end of the supporting part 612 is fixedly installed on the fixed component 62, and a part of the supporting part 612 is inclined. The lifting part 611 is provided with two supporting parts 612 arranged along the length direction of the mold cavity 5. The injection molding machine can drive the fixed component 62 to move upward, thereby moving the lifting component 61 and separating the finished part from the mold cavity 5.

[0074] Preferably, such as Figure 4 As shown, the mold of this utility model also includes a top plate 1, a hot runner plate 2, side plates 7 and a bottom plate 8.

There are multiple side plates 7. The moving platen 4, the bottom plate 8 and the multiple side plates 7 together form a lifting cavity. The fixing component 62 is located inside the lifting cavity and between the bottom plate 8 and the moving platen 4.

[0075] For example, such as Figure 4 As shown, the top plate 1 of the mold of this utility model is located at the top, the gate 11 is set on the top plate 1, the hot runner plate 2 is located below the top plate 1, the runner pipe 21 is installed on the hot runner plate 2, the fixed platen 3 is set below the hot runner plate 2, the top plate 1, the hot runner plate 2 and the fixed platen 3 are fixedly connected, which is the upper part of the mold, the moving platen 4 is located below the fixed platen 3, the bottom plate 8 is located below the moving platen 4, and the bottom plate 8 and the moving platen 4 are connected by four side plates 7, which constitute the lower part of the mold.

[0076] It should be noted that the present invention does not limit the number of lifting components 61. For example, those skilled in the art can set the number of lifting components 61 to 2, 4 or 6, etc. Such adjustments and changes to the specific number of lifting components 61 do not deviate from the principle and scope of the present invention and should be limited to the protection scope of the present invention.

[0077] Preferably, such as Figure 4 and Figure 7 As shown, the present invention has multiple lifting components 61, which are distributed at intervals along the length direction of the mold cavity 5 and arranged in two rows at intervals along the width direction of the mold cavity 5.

[0082] For example, such as Figure 4 As shown, the movable template 4 of this utility model is provided with a guide hole 43 that penetrates the movable template 4 in the vertical direction. The top end of the guide post 63 is inserted into the guide hole 43, and the bottom end of the guide post 63 is fixedly connected to the fixed component 62. When the finished part cools and solidifies, the injection molding machine drives the fixed component 62 to move upward, and the guide post 63 can move upward along the guide hole 43, thereby preventing the lifting component 61 from tilting.

[0083] It should be noted that the present invention does not limit the number of guide posts 63. For example, those skilled in the art can set the number of guide posts 63 to 2 or 4, etc. Such adjustments and changes to the specific number of guide posts 63 do not deviate from the principle and scope of the present invention and should be limited to the protection scope of the present invention.

[0087] For example, such as Figure 4 As shown, the elastic reset component 64 of this utility model is a spring. The spring is sleeved on the guide post 63. The top end of the spring abuts against the bottom wall of the moving template 4, and the bottom end of the spring abuts against the top wall of the fixed component 62. After the finished part cools and solidifies, the injection molding machine drives the fixed component 62 to move upward, thereby compressing the spring. After the finished part separates from the mold cavity 5, the injection molding machine separates from the fixed component 62, and the fixed component 62 can reset by the elastic force of the spring, thereby abutting against the base plate 8 again.
