Description

Technical Field

[0001] The present application relates to the field of mold technology, and in particular to a wind tube mold. Background Art

[0002] The air concentrator is an important component of the air circulation fan. Its main function is to store airflow and make the air supply more concentrated and long-distance. It is a key component to achieve long-distance air supply and accelerate air circulation.

[0003] During the production process, the air condenser is divided into four equal parts into four arc-shaped cylinder pieces. The operator uses a mold to injection mold the four arc-shaped cylinder pieces one by one. The injection molding method adopts single-hole injection molding, and the plastic melted into a fluid at high temperature is injected into the mold through a single injection hole. After molding, the mold is disassembled to take out the injection-molded arc-shaped cylinder piece, and then the four arc-shaped cylinder pieces are spliced ​​into an air condenser.

[0004] The above-mentioned production method of the arc-shaped cylinder piece requires disassembling the mold and taking out the formed arc-shaped cylinder piece from the top of the arc-shaped cylinder piece after each injection molding. The flexibility is poor and the demolding method of the arc-shaped cylinder piece is limited, resulting in slow demolding speed and low production efficiency. Summary of the invention

[0005] In order to help solve the problem of inconvenient demolding during the manufacturing of arc-shaped cylinder slices by existing injection molds, which leads to low production efficiency, the present application provides a wind collecting tube mold, which adopts the following technical solution: it includes an upper mold and a lower mold, and the upper mold is provided with an upper cavity matching the arc-shaped cylinder slice on the surface facing the lower mold, and the lower mold is provided with an injection molding seat, and the injection molding seat is provided with a lower cavity matching the arc-shaped cylinder slice on the surface facing the upper mold, the upper cavity is connected to the lower cavity to form a mold cavity, and a demolding seat is slidably connected to the lower mold, and the end face of the demolding seat facing the lower cavity is in contact with the injection molding seat.

[0006] Through the above technical scheme, the plastic melted into a fluid at high temperature, i.e., the injection liquid, is injected into the cavity to form the arc-shaped cylinder piece in one piece. After the operator takes out the upper mold, the demolding seat is disassembled. Then, the operator can take out the arc-shaped cylinder piece from one side or the top of the injection molding seat. While the demolding space is increased, the possibility of the arc-shaped cylinder piece being deformed due to scratches during the demolding process is reduced, thereby improving the injection molding quality of the arc-shaped cylinder piece. The demolding flexibility of the arc-shaped cylinder piece is stronger, and the demolding speed and production efficiency are improved.

[0007] In a specific possible implementation manner, a guide rail is provided on the surface of the lower mold facing the upper mold, a slide groove matching the guide rail is provided on the surface of the demoulding seat facing the guide rail, and the guide rail is slidably connected in the slide groove.

[0008] Through the above technical solution, the demoulding seat slides along the direction of the guide rail, and the guide rail provides a guiding effect on the moving direction of the demoulding seat, thereby improving the sliding stability of the demoulding seat.

[0009] In a specific possible implementation manner, the cross section of the guide rail is T-shaped.

[0010] Through the above technical solution, the guide rail with a T-shaped cross section reduces the possibility of shaking or offsetting of the demoulding seat during the sliding process, and improves the sliding stability of the demoulding seat.

[0011] In a specific possible implementation mode, a mounting bolt is passed through the guide rail, a thread groove matching the mounting bolt is formed on the surface of the lower mold facing the upper mold, and the mounting bolt is threadedly connected in the mounting groove.

[0012] Through the above technical solution, the operator can remove the lower guide rail from the lower mold by means of bolt disassembly, which is convenient for subsequent replacement and maintenance.

[0013] In a specific possible implementation manner, a positioning block is provided on the surface of the upper mold facing the lower mold, a positioning groove matching the positioning block is provided on the demoulding seat, and the positioning block is inserted into the positioning groove.

[0014] Through the above technical solution, the positioning block of the upper mold is inserted into the positioning groove of the demolding seat to position the demolding seat, which facilitates the rapid positioning between the upper mold and the demolding seat, improves the installation efficiency and reduces the possibility of deviation between the upper mold and the demolding seat.

[0015] In a specific possible implementation scheme, a guide plate is provided in the upper mold, a flow channel is opened in the guide plate, a feed pipe and a discharge pipe communicating with the flow channel are provided on the guide plate, and an output end of the discharge pipe is communicated with the cavity.

[0016] Through the above technical solution, the injection liquid flows from the feed pipe through the flow channel in the guide plate and then flows out of the discharge pipe and is injected into the mold cavity. The guide plate guides the injection liquid.

[0017] In a specific possible implementation manner, the number of the discharge pipes is three and they are evenly distributed on the guide plate.

[0018] Through the above technical scheme, since the arc-shaped cylinder piece is arc-shaped, the three evenly distributed discharge pipes facilitate the uniform injection of the injection liquid into the mold cavity, reducing the possibility of uneven thickness of the arc-shaped cylinder piece caused by uneven injection of the injection liquid, and improving the quality of the injection molding of the arc-shaped cylinder piece.

[0019] In a specific possible implementation scheme, the guide plate is provided with driving electric cylinders corresponding to the three discharge pipes respectively, and the output ends of the three driving electric cylinders are respectively provided with needle valves for opening and closing the flow channel.

[0020] Through the above technical solution, the driving electric cylinder is started to drive the needle valve to extend to block the flow channel corresponding to the discharge pipe in the guide plate. The needle valve is used to facilitate the control of the opening and closing of the flow channel, which is more flexible.

[0021] In a specific embodiment, a feeding funnel is provided at one end of the feeding tube away from the lower mold.

[0022] Through the above technical solution, the feeding funnel has a gathering effect on the injection liquid, thereby improving the efficiency of the injection liquid entering the feeding pipe.

[0023] In a specific possible implementation manner, a guide post is provided on the surface of the upper mold facing the lower mold, and a mounting groove matching the guide post is opened on the lower mold, and the guide post is inserted into the mounting groove.

[0024] Through the above technical solution, when the operator needs to lift the upper mold to take out the formed arc-shaped cylinder sheet, the guide column moves along the guide groove direction, and the guide groove limits the position of the guide column, thereby improving the stability when lifting the upper mold.

[0025] In summary, the present application has the following beneficial technical effects: the plastic melted into a fluid at high temperature, i.e., the injection liquid, is injected into the mold cavity to form the arc-shaped cylinder piece in one piece, and the operator removes the demolding seat after taking out the upper mold, and then the operator can take out the arc-shaped cylinder piece from one side or the top of the injection molding seat. While the demolding space is increased, the possibility of the arc-shaped cylinder piece being deformed due to scratches during the demolding process is reduced, thereby improving the injection molding quality of the arc-shaped cylinder piece, and the demolding flexibility of the arc-shaped cylinder piece is stronger, thereby improving the demolding speed and production efficiency.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-6 This application is described in further detail.

[0034] The embodiment of the present application discloses a wind concentrator mold.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The air concentrator mold includes an upper mold 1 and a lower mold 2. An upper cavity 7 matching the shape of the arc-shaped cylinder piece 4 is provided on the surface of the upper mold 1 facing the lower mold 2. An injection molding seat 3 is provided on the lower mold 2. A lower cavity 5 matching the size of the arc-shaped cylinder piece 4 is provided on the surface of the injection molding seat 3 facing the upper mold 1. The upper cavity 7 is connected with the lower cavity 5 to form a cavity matching the shape of the arc-shaped cylinder piece 4. A demolding seat 6 is slidably connected to the lower mold 2. The end surface of the demolding seat 6 facing the lower cavity 5 is in contact with the injection molding seat 3.

[0036] Therefore, the plastic melted into a fluid at high temperature, i.e., the injection liquid, is injected into the cavity to form the arc-shaped cylinder piece 4 in one piece. The operator lifts the upper mold 1 and removes the demolding seat 6. Then, the operator can take out the arc-shaped cylinder piece 4 from one side or the top of the injection molding seat 3. While the demolding space is increased, the possibility of the arc-shaped cylinder piece 4 being deformed due to scratches during the demolding process is reduced, thereby improving the injection molding quality of the arc-shaped cylinder piece 4. The demolding flexibility of the arc-shaped cylinder piece 4 is stronger, and the demolding speed and production efficiency are improved.

[0037] Reference Figure 2 and Figure 3 A guide post 19 is bolted on the surface of the upper mold 1 facing the lower mold 2, and a guide groove 20 matching the size of the guide post 19 is provided on the lower mold 2, and the guide post 19 is inserted into the guide groove 20. When the operator needs to lift the upper mold 1 to take out the formed arc-shaped cylinder sheet 4, the guide post 19 moves along the guide groove 20, and the guide groove 20 limits the position of the guide post 19, thereby improving the stability when lifting the upper mold 1.

[0038] Reference Figure 4 and Figure 5A guide rail 8 is provided on the surface of the lower mold 2 facing the upper mold 1. The cross section of the guide rail 8 is T-shaped. The guide rail 8 with a T-shaped cross section reduces the possibility of shaking or offsetting of the demolding seat 6 during the sliding process, and improves the sliding stability of the demolding seat 6. A slide groove 9 matching the size of the guide rail 8 is provided on the surface of the demolding seat 6 facing the guide rail 8, and the guide rail 8 is slidably connected in the slide groove 9. Therefore, the demolding seat 6 slides along the direction of the guide rail 8, and the guide rail 8 provides a guiding effect on the moving direction of the demolding seat 6, thereby improving the sliding stability of the demolding seat 6. A mounting bolt 21 is penetrated on the guide rail 8, and a threaded groove matching the size of the mounting bolt 21 is provided on the surface of the lower mold 2 facing the upper mold 1. The mounting bolt 21 is threadedly connected in the mounting groove. The operator can remove the lower guide rail 8 from the lower mold 2 by disassembling the bolts, which is convenient for the subsequent replacement and maintenance of the guide rail 8.

[0039] Reference Figure 2 and Figure 4 The upper mold 1 is bolted with a positioning block 10 on the surface facing the lower mold 2, and the demolding seat 6 is provided with a positioning groove 11 that matches the size of the positioning block 10, and the positioning block 10 is inserted into the positioning groove 11. Therefore, the positioning block 10 of the upper mold 1 is inserted into the positioning groove 11 of the demolding seat 6 to position the position of the demolding seat 6, which is convenient for rapid positioning between the upper mold 1 and the demolding seat 6, improves the installation efficiency, and reduces the possibility of deviation between the upper mold 1 and the demolding seat 6.

[0040] Reference Figure 5 The upper mold 1 is provided with a guide plate 12, a flow channel 13 is provided in the guide plate 12, a feed pipe 14 and a discharge pipe 15 communicating with the flow channel 13 are provided on the guide plate 12, a feed funnel 18 is installed at one end of the feed pipe 14 away from the lower mold 2, and the feed funnel 18 has a convergence effect on the injection molding liquid, thereby improving the efficiency of the injection molding liquid entering the feed pipe 14. Therefore, the injection molding liquid flows from the feed pipe 14 into the flow channel 13 in the guide plate 12, flows out of the discharge pipe 15, and then is injected into the mold cavity, and the guide plate 12 has a guiding effect on the injection molding liquid.

[0041] Reference Figure 5 , three discharge pipes 15 are provided and evenly distributed on the guide plate 12, and the output end of the discharge pipe 15 is communicated with the cavity. Since the arc-shaped cylinder piece 4 is arc-shaped, the three evenly distributed discharge pipes 15 facilitate the injection liquid to be evenly injected into the cavity, reducing the possibility of uneven thickness of the arc-shaped cylinder piece 4 caused by uneven injection of the injection liquid, and improving the quality of the injection molding of the arc-shaped cylinder piece 4.

[0042] Reference Figure 5 and Figure 6The guide plate 12 is provided with driving electric cylinders 16 corresponding to the three discharge pipes 15, and the output ends of the three driving electric cylinders 16 are respectively provided with needle valves 17 for opening and closing the flow channel 13. When the driving electric cylinder 16 is started, the needle valve 17 is driven to extend and block the flow channel 13 corresponding to the discharge pipe 15 in the guide plate 12. The needle valve 17 is used to control the opening and closing of the flow channel 13, which is more flexible.

[0043] The implementation principle of the embodiment of the present application is: the operator injects the injection liquid into the feed pipe 14 from the feed funnel 18, and the injection liquid flows out of the three discharge pipes 15 through the flow channel 13 in the guide plate 12 and is then injected into the cavity. After injection molding, the operator lifts the upper mold 1, slides the demolding seat 6 along the guide rail 8 to easily remove the demolding seat 6, and then the operator can remove the arc-shaped cylinder piece 4 from one side or the top of the injection molding seat 3. While the demolding space is increased, the possibility of deformation caused by scratches on the arc-shaped cylinder piece 4 during the demolding process is reduced, thereby improving the injection molding quality of the arc-shaped cylinder piece 4, and the demolding flexibility of the arc-shaped cylinder piece 4 is stronger, thereby improving the demolding speed and production efficiency.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
