Description

Technical Field

[0001] This invention belongs to the field of injection mold technology, and specifically relates to an injection mold with an insert. Background Technology

[0002] A phone case is an accessory used to protect a phone from scratches, impacts, and everyday wear and tear. Beyond providing physical protection, phone cases often incorporate decorative elements that can showcase personal style.

[0003] For phone cases that include accessories, current technology typically involves first producing the phone case using a mold, and then performing secondary processing to fix the accessories onto the phone case. During this secondary processing, the corresponding positions of the accessories and the phone case need to be determined before the attachment is properly installed.

[0004] The production of phone cases involves many steps and is quite complex. During the production process, on the one hand, the connection position between the accessories and the phone case is not stable, and the installation position of the two is prone to change, resulting in inconsistent product quality. On the other hand, when processing and fixing the accessories to the phone case, the phone case or accessories are easily damaged, which leads to a decrease in production quality and efficiency, and an increase in the production cost of phone cases. Summary of the Invention

[0005] The purpose of this application is to provide an injection mold with an insert to solve the aforementioned technical problems existing in the prior art.

[0006] This application is implemented as follows:

[0007] This application provides an injection mold with an insert, including an upper mold, a lower mold, a material picking assembly, and a driving mechanism. The material picking assembly is installed on the upper mold and is used to pick up the insert with a channel. The upper mold can dock with the lower mold to form an injection cavity for injecting injection molding material. When the upper mold and the lower mold are docked, the part of the material picking assembly that contacts the insert is located in the injection cavity. The driving mechanism is connected to the upper mold and is used to drive the upper mold to dock or separate from the lower mold. The driving mechanism is also used to drive the upper mold to pick up the insert.

[0008] The technical solution adopted in this invention can achieve the following beneficial effects:

[0009] In this application, a material-picking component is provided for picking up the insert, and the part of the material-picking component that contacts the insert is located in the injection molding cavity. This allows the insert picked up by the material-picking component to be integrally molded with the injection molding material, thus completing the fixation of the phone case and the insert during the injection molding process. The position of the insert in the injection molding cavity is stable, and the relative position of the injection-molded phone case and the insert is stable, ensuring the uniformity of product quality. Furthermore, using the insert to connect the phone case and accessories can avoid damage to the accessories and phone case during the installation of accessories, reducing the risk of damage to the accessories and phone case, improving the installation efficiency of accessories, thereby improving product production efficiency and reducing production costs.

[0010] Furthermore, this application combines the material-picking component and the upper mold, integrating the process of docking the upper and lower molds with the process of placing the insert into the lower mold. The insert can be placed in a preset position while the upper and lower molds are docking. After the phone case is injection molded, since the material-picking component is always in contact with the insert, it can drive the phone case to separate from the lower mold during the separation process of the upper and lower molds. The unloading process of the phone case can be completed by using the separation of the material-picking component and the insert. This achieves multi-functional integration, simplifies the production process of the phone case, simplifies the equipment, and eliminates multiple positioning components compared to the prior art, thereby reducing equipment costs.

Detailed Implementation

[0030] The following description provides many different embodiments or examples for implementing various features of the invention. The elements and arrangements described in the specific examples below are only for concise expression of the invention and are merely examples, not intended to limit the invention.

[0031] This application provides an injection mold with an insert, which can fix the insert 500 to the phone case 700 during the production process of the phone case 700, simplifying the overall process of assembling the phone case 700 and accessories and improving production efficiency.

[0032] refer to Figure 1 and Figure 2 As shown, the injection mold provided in this embodiment includes an upper mold 100, a lower mold 200, a material handling assembly 300, and a drive mechanism 400. The upper mold 100 and the lower mold 200 can be connected to form an injection cavity, which is used to pour injection molding material. The injection molding material cools and solidifies in the injection cavity to form a mobile phone case 700. The injection molding material can be a hot melt material.

[0033] The material-picking assembly 300 is used to pick up the insert 500 with the channel 510. The material-picking assembly 300 is mounted on the upper mold 100, and the upper mold 100 and the material-picking assembly 300 move synchronously. When the upper mold 100 and the lower mold 200 are connected to form an injection cavity, the part of the material-picking assembly 300 that contacts the insert 500 is located in the injection cavity. When the material-picking assembly 300 picks up and fixes the insert 500, the insert 500 is located in the injection cavity. During the process of the injection molding material cooling and fixing to form the mobile phone case 700, the insert 500 is fixed to the mobile phone case 700.

[0034] The insert 500 is selected as a component with a channel 510. The channel 510 serves two purposes: firstly, it facilitates mating with the material-picking assembly 300, allowing the material-picking assembly 300 to quickly pick up and fix the insert 500; secondly, it facilitates mating with accessories. The channel 510 may have threads inside, allowing for quick and easy fixing with accessories using the threads. In some embodiments, the insert 500 may have a nut structure, fixing the nut to the phone case 700, allowing for quick and convenient connection with accessories using the nut. Furthermore, since the connection between the nut and the accessory is a threaded connection, the user can also replace the accessory themselves.

[0035] The drive mechanism 400 is connected to the upper mold 100 and is used to drive the upper mold 100 to move. The movement of the upper mold 100 mainly includes: docking or separating the upper mold 100 from the lower mold 200, and picking up the insert 500. In use, the drive mechanism 400 controls the upper mold 100 to move and pick up the insert 500. After picking up the insert 500, the drive mechanism 400 can drive the upper mold 100 to dock with the lower mold 200. After the mobile phone case 700 is injection molded, the drive mechanism 400 can drive the upper mold 100 to separate from the lower mold 200.

[0036] In the embodiments provided in this application, the insert 500 is placed in the injection cavity. During the injection molding of the phone case 700, the phone case 700 and the insert 500 are fixed together to form an integral structure. The insert 500 is picked up by the material picking component 300. The relative position of the material picking component 300 and the upper mold 100 is stable, and the position of the insert 500 fixed to the material picking component 300 in the injection cavity is also stable, thereby ensuring the stability of the relative position of the insert 500 and the phone case 700, and ensuring the stability and uniformity of product quality.

[0037] Furthermore, by fixing the phone case 700 and the insert 500 directly during the injection molding process, and then connecting the phone case 700 and accessories directly through the insert 500, damage to the accessories and phone case 700 during the installation process can be avoided, reducing the risk of damage to the accessories and phone case 700, improving the installation efficiency of accessories, thereby increasing product production efficiency and reducing production costs.

[0038] During the injection molding process of the phone case 700, an insert 500 needs to be placed, requiring a corresponding mechanism to pick up and place it. If the material handling component 300 is separated from the upper mold 100, an additional robotic arm or similar device is needed to control the movement of the insert 500. Furthermore, during the movement of the insert 500, the position of the upper mold 100 must be carefully monitored to prevent collisions. However, this structure complicates the production equipment for the phone case 700, increases its cost, and correspondingly increases the cost of transferring the insert 500 to the phone case 700.

[0039] In some embodiments of this application, the material-picking component 300 is directly installed on the upper mold 100, and the drive mechanism 400 drives the upper mold 100 to move, which is equivalent to driving the material-picking component 300 to move. The material-picking component 300 is combined with the upper mold 100, and the process of docking the upper mold 100 with the lower mold 200 is combined with the process of placing the insert 500 into the lower mold 200. At the same time as the upper mold 100 docks with the lower mold 200, the insert 500 can be placed in a preset position, simplifying the overall production steps. After the phone case 700 is injection molded, since the material-picking component 300 and the insert 500 are always in contact, the material-picking component 300 is used to fix the insert 500. During the separation process of the upper mold 100 and the lower mold 200, the material-picking component 300 can drive the phone case 700 to separate from the lower mold 200, avoiding the additional process of removing the phone case 700 from the lower mold 200. Moreover, the upper mold 100 is fixed to the phone case 700 through the connection between the material picking component 300 and the insert 500. The phone case 700 can be unloaded directly by separating the material picking component 300 and the insert 500. The unloading process of the phone case 700 is combined with the unloading process of the insert 500, which further simplifies the production process of the phone case 700.

[0040] The injection mold provided in this application embodiment achieves multi-functional integration, simplifies the production process of the mobile phone case 700, and simplifies the production equipment of the mobile phone case 700. Compared with the prior art, it eliminates multiple positioning components, thereby reducing equipment costs. Furthermore, due to the simplification of production steps, the production rate of the mobile phone case 700 is correspondingly increased.

[0041] The drive mechanism 400 can drive the upper mold 100 to move, and the drive mechanism 400 can drive the upper mold 100 to the unloading position. Then, the material handling component 300 separates from the insert 500, thus completing the unloading of the mobile phone case 700. The loading position and the unloading position of the insert 500 can be located on the same straight line, thereby simplifying the movement path of the drive mechanism 400 driving the upper mold 100 and saving loading and unloading time.

[0042] refer to Figure 1 and Figure 2 As shown, a connecting arm 430 connects the drive mechanism 400 and the upper mold 100. The drive mechanism 400 drives the connecting arm 430 to move, thereby driving the upper mold 100 to move. In some embodiments, reference is made to... Figure 2As shown, the drive mechanism 400 includes a second motor 410 and a third motor 420. The second motor 410 and the third motor 420 are connected to drive the third motor 420 to rotate. The third motor 420 is connected to the connecting arm 430 to drive the connecting arm 430 to move along its axial direction. By activating the second motor 410, the upper mold 100 can be driven to rotate, changing its position on the horizontal plane and rotating it to the position of the insert 500 for picking up the insert 500. By activating the third motor 420, the upper mold 100 can be driven to move up and down, changing its position on the vertical plane and driving the upper mold 100 to dock or separate from the lower mold 200.

[0043] In some embodiments of this application, the material-taking assembly 300 and the insert 500 can be fixed by an inflatable fixing method. The material-taking assembly 300 includes a first conduit 310 and an airbag 320. One end of the first conduit 310 is connected to the airbag 320, and the other end is connected to an air source. The airbag 320 is used to insert into the hole 510 of the insert 500. The air source inflates the airbag 320 through the first conduit 310, allowing the airbag 320 to inflate and be fixedly connected to the insert 500. (Reference) Figure 3 , Figures 11 to 1 As shown in Figure 3, the airbag 320 is located at one end of the material handling assembly 300, and this end is located in the injection cavity when the upper mold 100 and the lower mold 200 are mated.

[0044] Since the airbag 320 is located inside the channel 510 of the insert 500, the inflated airbag 320 can fill the channel 510. During the injection molding process, since the airbag 320 occupies the space inside the channel 510 of the insert 500, the injection molding material can be prevented from flowing into the channel 510 of the insert 500.

[0045] In some embodiments of this application, the material handling assembly 300 further includes a second pipe 330 and a negative pressure hood 340, one end of the second pipe 330 being connected to the negative pressure hood 340 and the other end being connected to an air source. (See reference...) Figure 3 , Figures 11 to 13 As shown, a negative pressure cover 340 is fitted over the airbag 320 and is used to adsorb the embedded part 500. The airbag 320 is inserted into the channel 510 of the embedded part 500. The negative pressure cover 340 is fitted over the airbag 320 and contacts the surface of the embedded part 500. An air source can be used to evacuate the second pipe 330, so that a negative pressure is formed inside the negative pressure cover 340. The negative pressure cover 340 fitted over the airbag 320 adsorbs the embedded part 500 under negative pressure, thereby fixing the embedded part 500 to the negative pressure cover 340.

[0046] The airbag 320 and the negative pressure cover 340 work together to fix the material-picking assembly 300 and the insert 500. When unloading the insert 500, the process is reversed compared to picking it up. An air source is used to evacuate the airbag 320 through the first pipe 310, causing the airbag 320 to retract and thus disconnecting the connection between the airbag 320 and the insert 500. An air source is then used to blow air into the negative pressure cover 340 through the second pipe 330, releasing the negative pressure adsorption between the negative pressure cover 340 and the insert 500, thus disconnecting them. It is important to note that the air source connected to the airbag 320 and the air source connected to the negative pressure cover 340 are not the same.

[0047] In some embodiments of this application, the material handling assembly 300 further includes a moving member 350 and a power structure 360, see reference. Figure 13 As shown, both the airbag 320 and the negative pressure cover 340 are fixed to the axial end of the movable member 350. The first pipe 310 and the second pipe 330 are both located on the movable member 350. (Refer to...) Figure 14 As shown. The movable component 350 is movably connected to the upper mold 100. The power structure 360 ​​is fixed to the upper mold 100 and connected to the movable component 350, used to drive the movable component 350 to move along its axial direction, so that the airbag 320 and the negative pressure cover 340 move closer to or further away from the upper mold 100. The movable component 350 moves along its axial direction, changing its position to facilitate the pickup of the insert 500. The movable position of the movable component 350 can improve the overall flexibility of the injection mold and facilitate the pickup of the insert 500.

[0048] The power structure 360 ​​is generally installed on the side of the upper mold 100 away from the lower mold 200 to avoid affecting the mating of the upper mold 100 and the lower mold 200. The upper mold 100 has a first mating surface 110, see reference. Figure 16 and Figure 17 As shown, the first mating surface 110 is used to mate with the lower mold 200 to form an injection cavity. The upper mold 100 also has a movable channel 120, see reference. Figures 15 to 17 As shown. The movable channel 120 extends through the first mating surface 110 to ensure that the end of the movable part 350, which is movably disposed in the movable channel 120, can be located in the injection cavity. The first mating surface 110 is also provided with a mounting groove 130, see reference. Figure 17As shown, the mounting groove 130 is fitted outside and communicates with the movable channel 120. The negative pressure cover 340 can move into the mounting groove 130, and along the axial direction of the moving member 350, the length of the negative pressure cover 340 is greater than the depth of the mounting groove 130. That is, when the negative pressure cover 340 is installed in the mounting groove 130, part of the negative pressure cover 340 protrudes from the first mating surface 110. During the injection molding process of the phone case 700, because the negative pressure cover 340 tightly adheres to the insert 500, the space where the negative pressure cover 340 protrudes from the first mating surface 110 is occupied by the negative pressure cover 340, and this part will not be filled with injection molding material. That is, after the phone case 700 is injection molded, the insert 500 is recessed relative to the surface of the phone case 700. (Refer to...) Figures 7 to 10 As shown.

[0049] The surface of the phone case 700 that contacts the first mating surface 110 is typically the inner surface, and the insert 500 is recessed relative to the inner surface of the phone case 700. The phone case 700 is generally made of a flexible material to provide protection for the phone. The insert 500 is typically a rigid structure to ensure the stability of the connection between the accessory and the phone case 700. After the phone case 700 is assembled onto the phone, a certain distance is maintained between the insert 500 and the phone to prevent the insert 500 from impacting the phone. Additionally, a gasket can be installed between the insert 500 and the phone to provide cushioning.

[0050] By directly limiting the size of the negative pressure cover 340, a shallow groove is formed on the inner surface of the injection-molded phone case 700 at the position corresponding to the insert 500, without the need for additional equipment to block it. Furthermore, the connection between the negative pressure cover 340 and the insert 500 is achieved through negative pressure adsorption. By blowing air into the negative pressure cover 340 to release the negative pressure, the connection between the negative pressure cover 340 and the insert 500 can be released. Additionally, even if the molded phone case 700 adheres to the negative pressure cover 340 during the injection molding process, the connection points are few. By using the second pipe 330 to blow air into the negative pressure cover 340, the air source acts on the insert 500, causing the insert 500 and the phone case 700 to move away from the negative pressure cover 340, thereby separating the negative pressure cover 340 and the phone case 700. Therefore, it will not affect the unloading process of the phone case 700.

[0051] In some preferred embodiments, the inner diameter of the negative pressure cover 340 is smaller than the radial dimension of the insert 500 to ensure that the negative pressure cover 340 can completely fit the surface of the insert 500, facilitating negative pressure adsorption of the insert 500 and preventing the interior of the negative pressure cover 340 from communicating with the outside through the gap between it and the insert 500, which would weaken the negative pressure adsorption effect of the negative pressure cover 340 on the insert 500. Furthermore, the thickness of the edge of the negative pressure cover 340 can be set to be thicker, so that even if part of the negative pressure cover 340 deforms and protrudes outside the insert 500, the interior of the negative pressure cover 340 will not communicate with the outside.

[0052] The power structure 360 ​​drives the moving component 350 to move. In some embodiments, the power structure 360 ​​can be a telescopic structure such as a hydraulic rod or a telescopic rod, using its telescopic function to drive the moving component 350 to move. In other embodiments, the power structure 360 ​​may also include a first motor 361, a screw 362, and a movable block 363, see reference. Figure 13 As shown, the first motor 361 is connected to the screw 362, driving the screw 362 to rotate. The movable block 363 is threaded onto the outside of the screw 362, and the moving part 350 is fixedly connected to the movable block 363. The screw 362 rotates under the drive of the first motor 361. Since the moving part 350 passes through the movable channel 120, it converts the rotational motion of the screw 362 into the linear motion of the movable block 363, thereby driving the moving part 350 to move along its axial direction.

[0053] In some embodiments of this application, both the first pipe 310 and the second pipe 330 are connected to a gas source pipe 370, as shown in the reference. Figure 13 As shown, the air source pipe 370 is connected to the corresponding air source. The air source pipe 370 is a flexible hose. When the moving part 350 moves relative to the upper mold 100, the air source pipe 370 can change position with the moving part 350, thereby ensuring the normal use of the airbag 320 and the negative pressure cover 340.

[0054] Both the first pipe 310 and the second pipe 330 are disposed on the moving part 350. In some preferred embodiments, the moving part 350 includes a moving body and a covering layer. Both the first pipe 310 and the second pipe 330 are groove structures disposed on the circumferential sidewall of the moving body. The groove structure is easier to process and manufacture. The covering layer covers the groove opening of the first pipe 310 and the groove opening of the second pipe 330, thereby forming two pipe structures with good airtightness.

[0055] In some embodiments of this application, reference is made to Figures 4 to 6 , Figure 9 and Figure 1As shown in Figure 0, the lower mold 200 has a positioning protrusion 210, which is used to insert into the channel 510 of the insert 500. The positioning protrusion 210 on the lower mold 200 can position the insert 500 to ensure that the insert 500 is in a suitable position in the injection cavity during the injection molding process of the phone case 700. Furthermore, the positioning protrusion 210, by inserting into the channel 510 of the insert 500, occupies a portion of the space within the channel 510, thus preventing injection material from flowing into the channel 510.

[0056] Furthermore, the lower mold 200 has a second mating surface 220, which is used to mate with the upper mold 100 to form an injection cavity. The second mating surface 220 is provided with a positioning groove 230, which is used to place the insert 500. A positioning protrusion 210 is provided at the bottom of the positioning groove 230. The structure of the positioning groove 230 and the positioning protrusion 210 can be referred to Figures 4 to 6 As shown.

[0057] Because of the positioning groove 230, a stepped structure is formed between the bottom of the positioning groove 230 and the second mating surface 220. When the insert 500 is installed in the positioning groove 230, the insert 500 can effectively prevent the injection molding material from flowing into the positioning groove 230, thereby confining the injection molding material within the area corresponding to the second mating surface 220 and improving the product quality of the produced mobile phone case 700. At the same time, the insert 500 installed in the positioning groove 230 protrudes from the surface of the mobile phone case 700, which can reduce the probability of separation between the insert 500 and the mobile phone case 700 and improve the installation stability of the insert 500.

[0058] In some embodiments of this application, three upper molds 100, three material-picking components 300, and three driving mechanisms 400 are provided, with each corresponding to one another. The three upper molds 100 are all used to pick up the insert 500, dock with and separate from the lower mold 200, and unload the injection-molded phone case 700. However, the three upper molds 100 are in different processes at the same time. While one upper mold 100 is picking up the insert 500, another upper mold 100 is docking or separating from the lower mold 200, leaving one upper mold 100 unloading the phone case 700. The three upper molds 100 cooperate with the lower mold 200 sequentially, thereby improving the production efficiency of the phone case 700. Furthermore, the movement lines of the three upper molds 100 are identical, which can avoid collisions between them during operation.

[0059] In other embodiments of this application, the injection mold further includes a loading platform 610, a worktable 620, and a unloading platform 630, see reference. Figure 1As shown, the lower mold 200 is installed on the worktable 620, the loading platform 610 is used to place the insert 500, the upper mold 100 picks up the insert 500 on the loading platform 610 for loading, and the unloading platform 630 is used to place the injection-molded item, i.e., the mobile phone case 700, and the upper mold 100 unloads the mobile phone case 700 at the unloading platform 630.

[0060] The working process of the injection mold provided in this application embodiment includes:

[0061] The drive mechanism 400 drives the upper mold 100 to move to the position of the insert 500, and the picking component 300 picks up the insert 500. The specific picking process includes: the power structure 360 ​​drives the moving component 350 downwards, extending the airbag 320 into the channel 510 of the insert 500; the negative pressure cover 340 adheres to the surface of the insert 500; then the airbag 320 is inflated, causing it to expand and connect with the channel 510, fixing the insert 500; the negative pressure cover 340 is then used to apply negative pressure suction, using negative pressure to adhere and fix the insert 500, thus locking the insert 500. The power structure 360 ​​drives the moving component 350 upwards, retracting the negative pressure cover 340 into the mounting groove 130 of the upper mold 100.

[0062] The drive mechanism 400 drives the upper mold 100 to move above the lower mold 200 and then moves towards and docks with the lower mold 200, injecting injection material, i.e., hot melt material, into the injection cavity. The hot melt material and the insert 500 are molded together. After molding, the drive mechanism 400 drives the upper mold 100 to separate from the lower mold 200, and the material handling component 300 moves the insert 500 and the phone case 700 out of the lower mold 200.

[0063] The drive mechanism 400 drives the upper mold 100 to move to the unloading table 630. First, the internal pressure of the negative pressure cover 340 is increased, and air is blown out through the negative pressure cover 340 to disconnect the connection between the negative pressure cover 340 and the insert 500. Then, the negative pressure is drawn from the airbag 320 to shrink the airbag 320 and disconnect the expansion joint between the airbag 320 and the insert 500, allowing the mobile phone case 700 with the insert 500 to be placed on the unloading table 630, thus completing the unloading.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
