[0002] A phone case is an accessory used to protect a phone from scratches, bumps and daily wear and tear. Phone cases not only provide physical protection, but are often installed as decorative accessories that can show personal style.

[0003] For some mobile phone cases that can be installed with accessories, the prior art generally uses a mold to produce the mobile phone case first, and then performs secondary processing to fix the accessories on the mobile phone case. During the secondary processing, the corresponding positions of the accessories and the mobile phone case need to be positioned first, and then fixed.

[0004] The production of mobile phone cases involves many steps and is relatively complicated. In addition, during the production process, on the one hand, the connection position between the accessories and the mobile phone case is not stable, and the installation positions of the two are prone to change, resulting in unstable product quality. On the other hand, the mobile phone case or the accessories are easily damaged when the accessories are processed and fixed on the mobile phone case, resulting in reduced production quality and efficiency, and increasing the production cost of the mobile phone case. Summary of the invention

[0005] The purpose of this application is to provide an injection mold with an embedded part to solve the above-mentioned technical problems existing in the prior art.

[0006] This application is implemented as follows:

[0007] An embodiment of the present application provides an injection mold with an embedded part, 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 the material picking assembly is used to pick up the embedded part with a channel. The upper mold can be docked with the lower mold to form an injection cavity, and the injection cavity is used to pour injection material; when the upper mold is docked with the lower mold, the part of the material picking assembly that is in contact with the embedded part is located in the injection cavity; the driving mechanism is connected to the upper mold, and the driving mechanism is used to drive the upper mold to dock or separate with the lower mold. The driving mechanism is also used to drive the upper mold to pick up the embedded part.

[0008] The technical solution adopted by the present invention can achieve the following beneficial effects:

[0009] In the present application, a picking component is provided for picking up an embedded part, and the part of the picking component for contacting the embedded part is located in the injection molding cavity, so that the embedded part picked up by the picking component can be integrally formed with the injection molding material, and the mobile phone case and the embedded part are fixed during the injection molding process of the mobile phone case; the position of the embedded part in the injection molding cavity is stable, and the relative positions of the mobile phone case and the embedded part formed by injection molding are stable, thereby ensuring the uniformity of product quality; and, by connecting the mobile phone case and the accessories using the embedded part, it is possible to avoid damage to the accessories and the mobile phone case during the installation of the accessories, reduce the risk of damage to the accessories and the mobile phone case, and improve the installation efficiency of the accessories, thereby improving the production efficiency of the product and reducing the production cost.

[0010] In addition, the present application combines the material picking component and the upper mold together, and combines the process of docking the upper mold with the lower mold with the process of placing the embedded part in the lower mold, so that the embedded part can be placed in the preset position while the upper mold and the lower mold are docked; and after the injection molding of the mobile phone case is completed, since the material picking component is always in contact with the embedded part, during the separation process of the upper mold and the lower mold, the material picking component can drive the mobile phone case to separate from the lower mold, and the unloading process of the mobile phone case can be completed by separating the material picking component from the embedded part, thereby realizing multi-functional integration, simplifying the production process of the mobile phone case, simplifying the equipment, and eliminating multiple positioning components compared to the prior art, thereby reducing equipment costs.

DETAILED DESCRIPTION

[0030] The following description provides many different embodiments or examples for implementing different features of the present invention. The components and arrangements described in the following specific examples are only used to simplify the present invention and are only used as examples, not to limit the present invention.

[0031] The embodiment of the present application provides an injection mold with an insert, which can fix the insert 500 to the mobile phone case 700 during the production process of the mobile phone case 700, simplify the overall process of assembling the mobile phone case 700 and accessories, and improve production efficiency.

[0032] refer to Figure 1 and Figure 2 As shown, the injection mold provided in the embodiment of the present application includes an upper mold 100, a lower mold 200, a material taking assembly 300 and a driving mechanism 400. The upper mold 100 and the lower mold 100 can be docked to form an injection cavity, and the injection cavity is used to pour the injection material, and the injection material is cooled and solidified in the injection cavity to form a mobile phone shell 700. The injection material can be a hot melt material.

[0033] The picking assembly 300 is used to pick up the insert 500 having the hole 510. The picking assembly 300 is installed on the upper mold 100. The upper mold 100 and the 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 picking assembly 300 that is used to contact the insert 500 is located in the injection cavity. When the picking assembly 300 picks up the fixed insert 500, the insert 500 is located in the injection cavity. When the injection material is cooled and fixed to form the mobile phone case 700, the insert 500 is fixed to the mobile phone case 700.

[0034] The insert 500 is selected to have a hole 510. The hole 510 has two functions. One is to facilitate the cooperation with the material picking component 300, so that the material picking component 300 can quickly pick up and fix the insert 500; the other is to facilitate the cooperation with the accessories. The hole 510 can be provided with a thread inside, and the thread and the accessories are quickly fixed. In some embodiments, the insert 500 can select a nut structure, fix the nut to the mobile phone case 700, and use the nut to quickly and conveniently complete the connection with the accessories. And because the connection between the nut and the accessory is a threaded connection, the user can also replace the accessory by himself.

[0035] The driving 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: the upper mold 100 and the lower mold 200 are connected or separated, and the upper mold 100 picks up the insert 500. In use, the driving mechanism 400 controls the upper mold 100 to move and pick up the insert 500. After picking up the insert 500, the driving mechanism 400 can drive the upper mold 100 to connect with the lower mold 200. After the mobile phone case 700 is injection molded, the driving mechanism 400 can drive the upper mold 100 to separate from the lower mold 200.

[0036] In the embodiment provided by the present application, the insert 500 is placed in the injection molding cavity, and during the process of injection molding the mobile phone shell 700, the mobile phone shell 700 and the insert 500 can be fixed together to form an integral structure. The insert 500 is picked up by the material taking component 300, and the relative position of the material taking component 300 and the upper mold 100 is stable, and the position of the insert 500 fixed to the material taking component 300 in the injection molding cavity is also stable, thereby ensuring the stability of the relative position of the insert 500 and the mobile phone shell 700, and ensuring the stability and uniformity of product quality.

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

[0038] During the injection molding process of the mobile phone case 700, since the insert 500 needs to be placed, a corresponding mechanism needs to be set to pick up and place the insert 500. If the material picking component 300 is separated from the upper mold 100, it is necessary to set up an additional manipulator to control the movement of the insert 500, and during the movement of the insert 500, it is also necessary to pay attention to the position of the upper mold 100 to avoid collision with the upper mold 100. However, under this structure, the production equipment of the mobile phone case 700 will be complicated, the cost of the production equipment will increase, and the cost of converting the insert 500 to the mobile phone case 700 will also increase accordingly.

[0039] In some embodiments of the present application, the material taking component 300 is directly installed on the upper mold 100, and the driving mechanism 400 drives the upper mold 100 to move, that is, drives the material taking component 300 to move. The material taking 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. When the upper mold 100 and the lower mold 200 are docked, the insert 500 can be placed in a preset position, simplifying the overall production steps; after the injection molding of the mobile phone shell 700 is completed, since the material taking component 300 and the insert 500 are always in contact, the insert 500 is fixed by the material taking component 300. During the separation process of the upper mold 100 and the lower mold 200, the material taking component 300 can drive the mobile phone shell 700 to separate from the lower mold 200, avoiding the process of taking the mobile phone shell 700 out of the lower mold 200. Moreover, the fixation of the upper mold 100 and the mobile phone case 700 is achieved through the connection between the material removal component 300 and the insert 500. The unloading of the mobile phone case 700 can be achieved directly by separating the material removal component 300 and the insert 500. The unloading of the mobile phone case 700 is combined with the unloading process of the insert 500, which further simplifies the production process of the mobile phone case 700.

[0040] The injection mold provided in the embodiment of the present application realizes multi-functional integration as a whole, simplifies the production process of the mobile phone case 700, simplifies the production equipment of the mobile phone case 700, and eliminates multiple positioning components compared to the prior art, thereby reducing equipment costs. In addition, since the production steps are simplified, the production rate of the mobile phone case 700 is correspondingly increased.

[0041] The driving mechanism 400 can drive the upper mold 100 to move, and the driving mechanism 400 can drive the upper mold 100 to the unloading position, and then the material removal component 300 is separated from the insert 500, and the unloading of the mobile phone case 700 can be completed. The loading position and the unloading position of the insert 500 can be located on the same straight line, thereby simplifying the moving path of the upper mold 100 driven by the driving mechanism 400, saving loading and unloading time.

[0042] refer to Figure 1 and Figure 2 As shown, the driving mechanism 400 and the upper mold 100 are connected by a connecting arm 430, and the driving mechanism 400 drives the connecting arm 430 to move so as to drive the upper mold 100 to move. Figure 2As shown, the driving 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 turning on the second motor 410, the upper mold 100 can be driven to rotate, the position of the upper mold 100 can be changed on the horizontal plane, the upper mold 100 can be rotated to the position of the insert 500, and the insert 500 can be picked up. By turning on the third motor 420, the upper mold 100 can be driven to move up and down, the position of the upper mold 100 can be changed on the vertical plane, and the upper mold 100 can be driven to dock or separate with the lower mold 200.

[0043] In some embodiments of the present application, the fixing of the material taking component 300 and the insert 500 can be fixed by inflation. The material taking component 300 includes a first pipeline 310 and an airbag 320. One end of the first pipeline 310 is connected to the airbag 320, and the other end is connected to the air source. The airbag 320 is used to be inserted into the channel 510 of the insert 500. The air source inflates the airbag 320 through the first pipeline 310, and the airbag 320 can be inflated to be fixedly connected to the insert 500. Figure 3 , Figure 11 to Figure 1 As shown in FIG. 3 , the airbag 320 is located at one end of the material taking component 300 , and when the upper mold 100 and the lower mold 200 are docked, the end is located in the injection cavity.

[0044] Since the airbag 320 is located in the channel 510 of the insert 500, the inflated airbag 320 can fill the channel 510. During the process of pouring the injection molding material, the airbag 320 occupies the space in the channel 510 of the insert 500, which can prevent the injection molding material from flowing into the channel 510 of the insert 500.

[0045] In some embodiments of the present application, the material taking assembly 300 further includes a second pipeline 330 and a negative pressure cover 340, one end of the second pipeline 330 is connected to the negative pressure cover 340, and the other end is connected to the gas source. Figure 3 , Figures 11 to 13 As shown, the negative pressure cover 340 is sleeved outside the airbag 320, and the negative pressure cover 340 is used to absorb the embedded part 500. The airbag 320 is inserted into the channel 510 of the embedded part 500, and the negative pressure cover 340 is sleeved outside the airbag 320, and contacts with the surface of the embedded part 500. The air source can be used to evacuate the second pipeline 330, so that negative pressure is formed inside the negative pressure cover 340, and the negative pressure cover 340 sleeved outside the airbag 320 absorbs 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 cooperate with each other to achieve the fixation of the material picking assembly 300 and the insert 500. When the insert 500 is unloaded, in contrast to the process of picking up the insert 500, the airbag 320 is evacuated through the first pipeline 310 by the air source, so that the airbag 320 retracts, thereby releasing the connection between the airbag 320 and the insert 500. The negative pressure cover 340 is blown through the second pipeline 330 by the air source to release the negative pressure adsorption between the negative pressure cover 340 and the insert 500, and release the connection between the negative pressure cover 340 and the insert 500. It should be noted that the air source connected to the airbag 320 and the air source connected to the negative pressure cover 340 are not the same air source.

[0047] In some embodiments of the present application, the material taking assembly 300 further includes a moving member 350 and a power structure 360. Fig.13 As shown, the airbag 320 and the negative pressure cover 340 are both fixed to the axial end of the moving member 350. The first pipeline 310 and the second pipeline 330 are both arranged on the moving member 350, referring to Fig.14 The moving member 350 is movably connected to the upper mold 100, and the power structure 360 ​​is fixed to the upper mold 100. The power structure 360 ​​is connected to the moving member 350 and is used to drive the moving member 350 to move along its axial direction so that the airbag 320 and the negative pressure cover 340 are close to or away from the upper mold 100. The moving member 350 moves along its axial direction and changes its position to facilitate picking up the embedded part 500. The movable position of the moving member 350 can improve the flexibility of the entire injection mold and facilitate picking up the embedded part 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 docking of the upper mold 100 and the lower mold 200. The upper mold 100 has a first mating surface 110, Fig.16 and Fig.17 As shown, the first mating surface 110 is used to cooperate with the lower mold 200 to form an injection cavity. The upper mold 100 also has an active channel 120, referring to Figures 15 to 17 The movable channel 120 penetrates the first mating surface 110 to ensure that the end of the moving member 350 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, Fig.17As shown, the mounting groove 130 is sleeved outside the movable channel 120 and is connected to the movable channel 120. The negative pressure cover 340 can be moved into the mounting groove 130, and along the axial direction of the movable part 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 mobile phone case 700, since the negative pressure cover 340 tightly adsorbs the embedding part 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 injection molding of the mobile phone case 700 is completed, the embedding part 500 is recessed relative to the surface of the mobile phone case 700, refer to Figures 7 to 10 shown.

[0049] The surface of the mobile phone shell 700 that contacts the first mating surface 110 is usually the inner surface, and the insert 500 is recessed relative to the inner surface of the mobile phone shell 700. The mobile phone shell 700 is generally made of a flexible material to provide protection for the mobile phone. In order to ensure the stability of the connection between the accessory and the mobile phone shell 700, the insert 500 is usually a rigid structure. After the mobile phone shell 700 is assembled on the mobile phone, a certain distance is separated between the insert 500 and the mobile phone to prevent the insert 500 from causing a collision with the mobile phone. At the same time, a gasket can be installed between the insert 500 and the mobile phone to use the gasket to buffer between the insert 500 and the mobile phone.

[0050] By directly limiting the size of the negative pressure cover 340, a shallow groove is formed at the position corresponding to the inner surface of the injection-molded mobile phone shell 700 and the insert 500, without the need to use other equipment to block it. In addition, the connection between the negative pressure cover 340 and the insert 500 is achieved by negative pressure adsorption. By blowing the negative pressure cover 340 and releasing the negative pressure, the connection between the negative pressure cover 340 and the insert 500 can be released. In addition, even if the molded mobile phone shell 700 is adhered to the negative pressure cover 340 during the injection molding process of the mobile phone shell 700, there are not many connection positions between the two. The negative pressure cover 340 is blown by the second pipeline 330, and the air source acts on the insert 500, blowing the insert 500 and the mobile phone shell 700 to move in a direction away from the negative pressure cover 340, thereby separating the negative pressure cover 340 and the mobile phone shell 700. Therefore, it will not affect the unloading process of the mobile phone shell 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, so as to ensure that the negative pressure cover 340 can be completely attached to the surface of the insert 500, so as to facilitate negative pressure adsorption of the insert 500, and avoid the negative pressure cover 340 from communicating with the outside through the gap between the negative pressure cover 340 and the insert 500, which would weaken the negative pressure adsorption effect of the negative pressure cover 340 on the insert 500. In addition, 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 is deformed and protrudes outside the insert 500, the inside of the negative pressure cover 340 will not communicate with the outside.

[0052] The power structure 360 ​​drives the moving member 350 to move. In some embodiments, the power structure 360 ​​may be a telescopic structure such as a hydraulic rod or a telescopic rod, and utilizes the telescopic function to drive the moving member 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. Fig.13 As shown, the first motor 361 is connected to the screw rod 362 to drive the screw rod 362 to rotate, the movable block 363 is threadedly sleeved on the outside of the screw rod 362, and the moving member 350 is fixedly connected to the movable block 363. The screw rod 362 rotates under the drive of the first motor 361, and since the movable member 350 is inserted into the movable channel 120, the rotational motion of the screw rod 362 is converted into a linear motion of the movable block 363, thereby driving the movable member 350 to move along its axial direction.

[0053] In some embodiments of the present application, the first pipeline 310 and the second pipeline 330 are both connected to the gas source pipeline 370, see Fig.13 As shown, the air source pipe 370 is connected to the corresponding air source. The air source pipe 370 is a hose. When the moving member 350 moves relative to the upper mold 100, the air source pipe 370 can change position following the movement of the moving member 350, thereby ensuring the normal use of the airbag 320 and the negative pressure cover 340.

[0054] The first pipeline 310 and the second pipeline 330 are both arranged on the moving part 350. In some preferred embodiments, the moving part 350 includes a moving body and a coating layer. The first pipeline 310 and the second pipeline 330 are both groove structures arranged on the circumferential side wall of the moving body. The groove structure is easier to process and manufacture. The coating layer covers the groove openings of the first pipeline 310 and the groove openings of the second pipeline 330, thereby forming two pipeline structures with good airtightness.

[0055] In some embodiments of the present application, reference Figures 4 to 6 , Fig. 9 and Figure 10, the lower mold 200 has a positioning protrusion 210, and the positioning protrusion 210 is used to be inserted 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 located at a suitable position in the injection cavity during the injection molding process of the mobile phone case 700. In addition, the positioning protrusion 210 is inserted into the channel 510 of the insert 500, and can occupy a part of the space in the channel 510, which can prevent the injection material from flowing into the channel 510.

[0056] Further, the lower mold 200 has a second mating surface 220, which is used to cooperate with the upper mold 100 to form an injection cavity. The second mating surface 220 is provided with a positioning groove 230, and the positioning groove 230 is used to place the insert 500. The 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 refer to Figures 4 to 6 shown.

[0057] Since the positioning groove 230 is provided, a step-like 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 material from flowing into the positioning groove 230, thereby limiting the injection material to the range 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 is arranged to protrude relative to the surface of the mobile phone case 700, which can reduce the probability of separation of the connection position between the insert 500 and the mobile phone case 700, and improve the installation stability of the insert 500.

[0058] In some embodiments of the present application, three upper molds 100, material taking components 300 and driving mechanisms 400 are provided, and the upper molds 100, material taking components 300 and driving mechanisms 400 are arranged one by one. The three upper molds 100 are all used to pick up the insert 500, dock and separate with the lower mold 200, and unload the injection-molded mobile phone shell 700, but the three upper molds 100 are in different processes at the same time. When one of the upper molds 100 picks up the insert 500, another upper mold 100 is in the process of docking or separation with the lower mold 200, and the remaining upper mold 100 is unloading the mobile phone shell 700. The three upper molds 100 cooperate with the lower mold 200 in turn, thereby improving the production efficiency of the mobile phone shell 700.
