Description

Technical Field

[0001] This application relates to the field of injection molding technology, and more specifically to an injection molding apparatus. Background Technology

[0002] With the development of technology, smart products are becoming more and more common. Conductive components are embedded on the outer surface of these products to enable electrical connections and facilitate intelligent control. In the production of some injection-molded products, it is necessary to mold the conductive components onto the outer surface of the product. Therefore, before injection molding, the conductive components need to be positioned inside the injection cavity.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] With the development of technology, smart products are becoming more and more common. Conductive components are embedded on the outer surface of these products to enable electrical connections and facilitate intelligent control. In the production of some injection-molded products, it is necessary to mold the conductive components onto the outer surface of the product. Therefore, before injection molding, the conductive components need to be positioned inside the injection cavity.

[0022] In related technologies, positioning holes are formed on the conductive component, and positioning protrusions are set in the injection cavity. The conductive component is connected to the positioning protrusions manually or by a robotic arm and attached to the injection cavity wall. However, the space of the injection cavity is small, and it is impossible to accurately position the conductive component on the injection cavity wall manually or by a robotic arm, resulting in low efficiency. Furthermore, the robotic arm is prone to contact with the mold, damaging the mold. To solve or improve the problem of low positioning accuracy of the conductive component, this application provides an injection molding apparatus.

[0023] The following is combined with Figures 1 to 15 This describes an embodiment of the present application.

[0024] According to an embodiment of this application, an injection molding apparatus is provided, comprising: The mold is provided with an injection cavity, and the mold has at least one first channel 3 communicating with the injection cavity, with the first port 304 of the first channel 3 being close to the injection cavity; Telescopic mechanism 4 is installed on the mold. The telescopic end of telescopic mechanism 4 is used to install conductive component 7. The telescopic end of telescopic mechanism 4 is adapted to telescopically switch between a first position and a second position. In the first position, the telescopic end of telescopic mechanism 4 is located outside the first channel 3. In the second position, the telescopic end of telescopic mechanism 4 seals the first port 304 and is flush with the first port 304. The conductive component 7 is located inside the injection cavity.

[0025] In this embodiment, such as Figure 2 , Figure 6 , Figure 7 and Figure 10 As shown, a conductive element 7 is installed on the telescopic end of the telescopic mechanism 4. The telescopic end of the telescopic mechanism 4 passes through the first channel 3 and moves along the first channel 3 to the first port 304. The telescopic end of the telescopic mechanism 4 is sealed and flush with the first port 304, so that the conductive element 7 is located in the injection cavity. Molding material is injected into the injection cavity, and the conductive element 7 and the molding material are combined to form an injection molded product. The position of the first port 304 corresponds to the installation position of the conductive element 7. By setting the first channel 3, the position of the conductive element 7 is accurately positioned, thereby improving the positioning accuracy of the conductive element 7 in the molded product with the conductive element 7.

[0026] Compared to related technologies, this embodiment is simpler to operate and more accurate in positioning by setting a positioning protrusion in the injection cavity and setting a positioning hole on the conductive component 7, and positioning the conductive component 7 on the positioning protrusion by hand or robotic arm.

[0027] In one embodiment, the mold includes: The first mold 1 is provided with a first molding groove and an injection hole 101 is provided in the first mold 1, which is connected to the first molding groove. The second mold 2 is provided with a second molding groove. The second mold 2 and the first mold 1 are aligned along the first direction X. The first molding groove and the second molding groove form an injection cavity. The second mold 2 is provided with a first channel 3.

[0028] In one embodiment, such as Figure 2 As shown, the second mold 2 includes: The fixed mold 201 is provided with a second molding groove. The side wall of the second molding groove has a notch 2011, which communicates with the second molding groove. A molding column 8 is provided in the second molding groove.

In the open position, the sliding mold is used to remove the injection molded product. In the closed position, the sliding mold and the fixed mold form a second molding groove. The sliding mold 202 has a first channel 3.

[0029] In this embodiment, such as Figure 2 As shown, the sliding mold 202 is slidably connected to the notch 2011. When the sliding mold 202 is in the open position, it opens the injection cavity, making it easy to remove the injection molded product formed in the injection cavity. When producing the next product, the sliding mold 202 moves to the closed position, forming a complete injection cavity with the fixed mold 201 and the first mold 1 for injection molding.

[0030] A first channel 3 is opened on the sliding mold 202. When the telescopic end of the telescopic mechanism 4 is in the second position, the conductive component 7 is fixed at the first port 304. The telescopic end of the telescopic mechanism 4 moves to the closed position with the sliding mold 202.

[0031] like Figure 1 and Figure 2 As shown, it also includes three third molds 9. The fixed mold 201 is provided with four notches 2011. The three third molds 9 and the sliding mold 202 are installed on the four notches 2011 in a one-to-one correspondence. Except for not having the first channel 3, the three third molds 9 have the same structure as the sliding mold 202.

[0032] Specifically, all three third molds 9 can switch between their respective open and closed positions. When the three third molds 9 are in the open position and the sliding mold 202 is in the open position, all three third molds 9 and the sliding mold 202 are away from the injection cavity. When the three third molds 9 are in the closed position and the sliding mold 202 is in the closed position, the three third molds 9, the sliding mold 202 and the first mold 1 form the injection cavity.

[0033] Specifically, such as Figure 2 As shown, the two sides of the three third molds 9 and the sliding mold 202 are provided with second protrusions 2023, and the inner wall of the corresponding notch 2011 is provided with a second groove 13 corresponding to the second protrusion 2023. The second protrusion 2023 slides along the second groove 13.

[0034] Specifically, a forming column 8 is set up, and an annular gap is formed between the three third molds 9 and the sliding mold of the forming column 8, which is used to prepare barrel-shaped parts.

[0035] Specifically, such as Figure 13 As shown, it also includes multiple guide rods 11, which are arranged on the first mold 1 along the first direction X. The fixed mold 201 is provided with multiple guide holes 10 corresponding to the multiple guide rods 11, and the multiple guide rods 11 and the multiple guide holes 10 are slidably connected in a one-to-one correspondence.

[0036] In one embodiment, such as Figure 3 , Figure 4 and Figure 5 As shown, the telescopic mechanism 4 includes: Connector 401 is connected to the fixed mold 201; The drive cylinder 402 is connected to the connector 401, and the telescopic rod of the drive cylinder 402 is arranged corresponding to the first channel 3; The drive block 403 is a telescopic end. The drive block 403 includes a connecting part 4031 and at least one sealing part 4032. The connecting part 4031 is connected to the sealing part 4032. The connecting part 4031 is connected to the telescopic rod of the drive cylinder 402. The end of the sealing part 4032 away from the connecting part 4031 is used to install the conductive element 7. In the first position, the sealing part 4032 is located outside the first channel 3. In the second position, the sealing part 4032 seals the first port 304 and is flush with the first port 304.

[0037] In this embodiment, such as Figure 4 As shown, the connector 401 includes: a connecting plate 4011, a support plate 4012, two guide plates 4013, and a mounting plate 4014. The connecting plate 4011 is connected to the fixed mold 201 and is located below the notch 2011 away from the first mold 1. The support plate 4012 is fixed to the connecting plate 4011. The two guide plates 4013 are connected to both sides of the support plate 4012, and a slide is formed between the two guide plates 4013. The bottom of the opposite sidewalls of the two support plates 4012 are provided with corresponding first slide grooves 12. The two sides of the connecting part 4031 are provided with first protrusions 40315, and the first protrusions 40315 are slidably connected to the first slide grooves 12.

[0038] Specifically, such as Figure 4 As shown, the mounting plate 4014 is connected to the end of the support plate 4012 away from the fixed mold 201. The mounting plate 4014 has a through hole 40141 corresponding to the slide. The drive cylinder 402 is mounted on the mounting plate 4014. The telescopic rod of the drive cylinder 402 passes through the through hole 40141 into the slide and is connected to the connecting part 4031.

[0039] Specifically, drive cylinder 402 is a pneumatic cylinder.

[0040] Specifically, the direction of the first chute 12 is the same as the direction of the first channel 3.

[0041] Specifically, such as Figure 5 As shown, the two first slide grooves 12 are provided with a third inclined surface 14 near the port of the fixed mold 201, which facilitates the retraction of the drive block 403 into the first slide groove 12.

[0042] It should be noted that in the first position, the connecting part 4031 slides into the first groove 12, and the sealing part 4032 is located outside the first channel 3.

[0043] Specifically, the connecting plate 4011 is a T-shaped plate, the horizontal plate of the T-shaped plate is fixed on the fixed mold 201, and the support plate 4012 is fixed on the vertical plate of the T-shaped plate.

[0044] In one embodiment, such as Figure 9 and Figure 10 As shown, the first channel 3 includes a first segment 301 and a second segment 302 arranged in the direction of moving from the first position to the second position. A first limiting step 303 is formed at the junction of the first segment 301 and the second segment 302. The second segment 302 is connected to the injection cavity. A second limiting step 4033 is formed at the junction of the connecting part 4031 and the sealing part 4032. In the second position, the second limiting step 4033 abuts against the first limiting step 303.

[0045] In this embodiment, the second limiting step 4033 abuts against the first limiting step 303, and the sealing part 4032 seals the first port 304, thereby enabling the sealing part 4032 to be positioned.

[0046] In one embodiment, such as Figure 3 as well as Figures 11 to 14 As shown, it also includes a limiting member 5, which includes a limiting rod 502. A through hole 2021 is provided on the sliding mold 202, which communicates with the first channel 3. A limiting groove 4031 is provided on the connecting part 4031 corresponding to the through hole 2021. The limiting rod 502 is adapted to move and switch between the unlocked position and the locked position along the first direction X. In the unlocked position, the limiting rod 502 is away from the sliding mold 202. In the locked position, the limiting rod 502 passes through the through hole 2021 and is inserted into the limiting groove 40311 to fix the sealing part 4032 in the second position.

[0047] In this embodiment, such as Figure 12 and Figure 14As shown, in the locked position, the limiting rod 502 passes through the through hole 2021 and is inserted into the limiting groove 40311, fixing the connecting part 4031 and the sliding mold 202 to form a whole. At this time, the second limiting step 4033 abuts against the first limiting step 303, so that the sealing part 4032 seals the first port 304.

[0048] In one embodiment, the limiting rod 502 is arranged at an angle. When the limiting rod 502 moves from the unlocked position to the locked position, it can drive the sliding mold 202 to move from the first position to the second position, so that the sliding mold 202 slides from the open position to the closed position.

[0049] In this embodiment, such as Figure 14 As shown, the limiting rod 502 is arranged at an angle. When it moves from the unlocked position to the locked position, the limiting rod 502 drives the sliding mold 202 to move from the first position to the second position.

[0050] Specifically, the limiting component 5 includes two limiting rods 502, and two through holes 2021 are opened on the sliding mold 202, through which the two limiting rods 502 pass.

[0051] In one embodiment, such as Figures 12 to 14 As shown, the limiting member 5 also includes: A connecting block 501 is installed on the first mold 1. The connecting block 501 is connected to the limiting rod 502. A plug-in block 5011 is provided on the connecting block 501. A plug-in hole 4031 is provided on the connecting part 4031 corresponding to the plug-in block 5011. The inner wall of the plug-in hole 40312 is set as a first inclined surface 40313. A second inclined surface 50111 is provided on the plug-in block 5011 corresponding to the first inclined surface 40313. The sliding mold 202 has a through hole 2022 corresponding to the plug-in block 5011. The through hole 2022 passes through the first channel 3. The plug-in hole 40312 is arranged corresponding to the through hole 2022. When the connecting block 501 moves from the unlocked position to the locked position, the first inclined surface 40313 slides and abuts against the second inclined surface 50111 to drive the sealing part 4032 to move from the first position to the second position and limit the sealing part 4032 to the second position.

[0052] In this embodiment, during the process of inserting the limiting rod 502 into the through hole 2021, the plug block 5011 is inserted into the plug hole 40312 and passes through the through hole 2022. The first inclined surface 40313 slides against the second inclined surface 50111, driving the sealing part 4032 and the sliding template to move from the first position to the second position, forming an injection cavity.

[0053] Specifically, such as Figure 1 and Figure 14As shown, there are four limiting members 5, which correspond to three third molds 9 and sliding mold 202. During the process of the first mold 1 and the second fixed mold 201 being engaged, the limiting rod 502 is inserted into the through hole 2021, and the plug block 5011 is inserted into the plug hole 40312 and passes through the through hole 2022, closing the three third molds 9 and sliding mold 202 together to form an injection cavity with the first mold 1.

[0054] In one embodiment, a vacuum pump is also included. A second channel is provided in the drive block 403. The second channel is provided with a first suction port 6 and a second suction port 16. The first suction port 6 is located on the end face of the sealing part 4032 near the injection cavity, and the second suction port 16 is connected to the vacuum pump.

[0055] Specifically, such as Figure 3 As shown, the vacuum pump is connected to the second suction port 16, and the conductive component 7 is installed on the end face of the sealing part 4032. The vacuum pump adsorbs the conductive component 7 onto the first suction port 6, which facilitates the installation of the conductive component 7 on the sealing part 4032. After the injection molding is completed, the vacuum pump is turned off, which facilitates the separation of the conductive component 7 from the sealing part 4032.

[0056] Specifically, the second suction port 16 is connected to the vacuum pump via a pipe.

[0057] In one embodiment, such as Figure 10 As shown, the first port 304 of the first channel 3 is configured as a flared mouth, with the end near the injection cavity being the small end. In the second position, the sealing part 4032 seals the small end. And / or, the first channel 3 is provided with a second port 305, the second port 305 is configured as a flared mouth, and the end away from the injection cavity is the large mouth end.

[0058] In this embodiment, such as Figure 10 As shown, the first port 304 is configured as a flared mouth, and the end of the flared mouth near the injection cavity is a small end. When the position of the conductive component 7 on the sealing part 4032 is offset, the position of the conductive component 7 can be adjusted to the accurate position after being guided by the flared mouth.

[0059] The second port 305 of the first channel 3 is a flared opening, with the end furthest from the injection cavity being the larger opening, which facilitates the sealing part 4032 to pass into the first channel 3.

[0060] In one specific embodiment, the second segment 302 of the first channel 3 is provided with two branch channels, and the sealing part 4032 is provided with two sealing segments. In the second position, the two sealing segments are located in the two branch channels, and the ends of the two sealing segments away from the connecting part 4031 are provided with a first suction port 6.

[0061] Specifically, the second channel includes two suction channels and a main channel. The main channel is located at the connecting part 4031 and is connected to the second suction hole. The two suction channels are set in two sealing sections, with one end connected to the main channel and the other end connected to the corresponding first suction port 6.

[0062] In one embodiment, the end of the connecting part 4031 near the drive cylinder 402 is provided with a connecting groove 40314, and the telescopic rod of the drive cylinder 402 is detachably connected to the connecting groove 40314.

[0063] like Figure 13 As shown, the connecting groove 40314 is a T-shaped groove, and one end of the telescopic rod of the drive cylinder 402 is connected to a T-shaped block 15. The T-shaped groove and the T-shaped block 15 are detachably connected.

[0064] The following is an example, combined with Figures 1 to 15 A comprehensive explanation of all the above-mentioned plans is provided.
