Description

Technical Field

[0001] This utility model relates to the technical field of injection molding demolding equipment, specifically to a demolding device for injection molded mobile phone protective cases. Background Technology

[0002] A demolding device is a device used during the molding process to eject or push the molded product out of the mold cavity through mechanical or hydraulic means when the mold is opened, so that it can be processed or treated later.

[0003] Existing mobile phone case injection molding and demolding devices are prone to developing tiny gaps or deformations after prolonged use. This causes the injection molding material to leak through these gaps under high pressure, which not only contaminates the inside of the mold but also causes defects, bubbles, or flash on the surface of the protective case. Utility Model Content

[0004] To solve the above problems, this utility model provides a demolding device for injection molded mobile phone cases, which avoids the problem that existing demolding devices for injection molding of mobile phone cases are prone to developing tiny gaps or deformations after long-term use. This causes the injection molding material to leak through these gaps under high pressure, which not only contaminates the inside of the mold, but also causes defects, bubbles or flash on the surface of the protective case.

[0005] To solve the above technical problems, the technical solution provided by this utility model is as follows: a demolding device for injection molded parts of mobile phone protective cases, including a lower mold, four positioning rods are connected through the periphery of the lower mold, an upper mold is connected through the upper part of the positioning rods, a sealing sleeve is fixedly connected to the lower side of the upper mold, a fixing block is provided on the upper part of the lower mold, a lifting device is provided inside the fixing block, and a mold clamping device is provided on the upper part of the lifting device;

[0006] The clamping device includes a bidirectional motor fixed to the upper part of the lifting device. Both output ends of the bidirectional motor are connected to screw rods. A moving block is connected through screw rods. A clamping plate is fixedly connected to the upper side of the moving block.

[0007] As an improvement, a threaded hole is provided in the middle of the moving block, and the moving block is threadedly connected to the screw.

[0008] As an improvement, the lifting device includes a drive motor fixed inside the lower mold, the output end of the drive motor is connected to a sleeve, a screw is provided inside the sleeve, and a fixing box is fixed to the top of the screw.

[0009] As an improvement, the inner side of the sleeve is provided with threads, and the sleeve is threadedly connected to the screw.

[0010] As an improvement, the fixing box is provided with sliding grooves on both sides near the card plate.

[0011] As an improvement, the fixing block has a cavity inside, and the fixing block has sliding grooves on both sides near the card plate.

[0012] The advantages of this invention compared to the prior art are as follows: by locking the sealing sleeve and the fixing block, leakage of injection molding material can be prevented, and the mold-locking device inside the fixing block can directly demold the protective shell. This avoids the problem that existing mobile phone protective shell injection molding demolding devices are prone to developing tiny gaps or deformations after long-term use, which can cause injection molding material to leak through these gaps under high pressure. This not only contaminates the inside of the mold, but also causes defects, bubbles, or flash on the surface of the protective shell. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] In specific implementation, this utility model is combined with Figures 1 to 3 A demolding device for injection molded parts of mobile phone protective cases includes a lower mold 1, four positioning rods 2 are connected through the periphery of the lower mold 1 to ensure precise alignment of the mold, an upper mold 3 is connected through the upper part of the positioning rods 2, a sealing sleeve 4 is fixedly connected to the lower side of the upper mold 3, and a fixing block 5 is provided on the upper part of the lower mold 1.

[0019] In the implementation of this utility model, the upper mold 3 and the lower mold 1 achieve a tight fit between the upper mold and the lower mold, and the sealing sleeve 4 is engaged with the fixing block 5 to prevent the raw material from accidentally seeping into the interior of the fixing block 5 during the injection molding process.

[0020] The lifting device 6 is equipped with a clamping device 7 on its upper part. The clamping device 7 includes a bidirectional motor 701 fixed on the upper part of the lifting device 6. Both output ends of the bidirectional motor 701 are connected to screws 702. Screws 702 are connected to moving blocks 703 through the screws 702. A threaded hole is provided in the middle of the moving block 703. The moving block 703 is threadedly connected to screws 702. A clamping plate 704 is fixedly connected to the upper side of the moving block 703. A cavity is provided inside the fixed block 5. Sliding grooves are provided on both sides of the fixed block 5 near the clamping plate 704.

[0021] In the implementation of this utility model, after injection molding is completed, the bidirectional motor 701 is started, causing the screw 702 to rotate, which drives the clamping plate 704 on the upper side of the threaded moving block 703 to move, thus locking the mobile phone case through the camera slot, which greatly facilitates the subsequent demolding steps.

[0022] The fixed block 5 is equipped with a lifting device 6. The lifting device 6 includes a drive motor 601 fixed inside the lower mold 1. The output end of the drive motor 601 is connected to a sleeve 602. The sleeve 602 is equipped with a screw 603. The inner side of the sleeve 602 is provided with threads. The sleeve 602 is threadedly connected to the screw 603. The top of the screw 603 is fixed with a fixing box 604. The fixing box 604 is provided with sliding grooves on both sides near the card plate 704.

[0023] In the implementation of this utility model, by starting the drive motor 601, the sleeve 602 rotates, which drives the threaded screw 603 to move up and down. When the screw 603 rises, the fixing box 604 rises accordingly. The clamping plate 704 in the clamping device 7 applies a pushing force to the mobile phone protective case, realizing an easy and precise demolding operation.
