Description

Technical Field

[0001] This utility model belongs to the field of injection molding equipment technology, specifically relating to an internal insert assembly and disassembly device. Background Technology

[0002] In the injection molding industry, inserts are common mold components, typically used to embed metal or other materials during the injection molding process to reinforce specific parts of a product or achieve complex functions. In the molding of complex structures such as thread forming or insert molding, inserts need to be removable from the mold to improve mold flexibility, production efficiency, and product quality. For example, the casings of electronic products such as mobile phones or computers require inserts to be removed after molding.

[0003] In the injection molding process of electronic product casings such as mobile phones or computers, inserts also need to be removed from the mold to embed metal nuts or threaded inserts into the molded product, achieving the threaded connection function of the casing. After the injection-molded product is removed, the inserts need to be reinstalled into the mold for re-injection molding. Currently, the removal and installation of inserts is usually done manually. However, because the inserts are hot and heavy when first removed, manual operation is not only prone to causing injury but also labor-intensive and inefficient. Therefore, it is necessary to design a device that can replace manual removal and installation of inserts to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide an internal insertion device for disassembly and assembly, so as to solve the problems mentioned in the background art.

Detailed Implementation

[0035] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. However, those skilled in the art will understand that the embodiments described below are only some embodiments of this utility model, not all embodiments, and are only used to illustrate this utility model, and should not be regarded as limiting the scope of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Where specific conditions are not specified in the embodiments, conventional conditions or conditions recommended by the manufacturer shall be followed. Where the manufacturers of reagents or instruments are not specified, they are all conventional products that can be purchased commercially.

[0036] like Figure 1-11 As shown, an insert assembly / disassembly device includes a main mounting base 1, an insert assembly / disassembly mechanism 2 on the main mounting base 1, an insert assembly / disassembly mechanism 2 including a positioning fixture 201 for carrying the insert, an assembly / disassembly component 202 below the positioning fixture 201, the assembly / disassembly component 202 being detachably connected to the core of the insert, and an ejection component 203 for driving the corner of the insert to move on the side of the positioning fixture 201.

[0037] The mold insert for the casing of electronic products such as mobile phones or computers typically consists of a frame, a core insert located in the middle, and surrounding corner parts. Generally, the core and corner parts are slidably connected. To facilitate demolding, the core is usually designed as a wedge-shaped structure, narrower at the top and wider at the bottom, and adjacent corner parts also use wedge-shaped designs to cooperate with each other. When the core insert moves downwards, space is created for the corner parts to move laterally. As the corner parts move laterally towards the core insert, the overall size of the insert decreases, making it easy to remove the injection-molded product.

[0038] Specifically, the disassembly and assembly component 202 is used to drive the core of the insert to move up and down. When the disassembly and assembly component 202 is connected to the core of the insert, the disassembly and assembly component 202 drives the core of the insert to move down. The ejection component 203 drives the corners of the insert to move towards the center in turn, thereby reducing the overall size of the insert.

[0039] When the disassembly and assembly component 202 moves the core of the insert upward, the core of the insert pushes the corner part outward and returns to its original position. At this time, the insert is put back into its original position and can be put into use again.

[0040] In this embodiment, the disassembly / assembly assembly 202 includes a first mounting plate 2021 slidably connected to the upper surface of the main mounting base 1. Specifically, the first mounting plate 2021 is slidably connected to the main mounting base 1 via a linear module, and the first mounting plate 2021 is driven to move by a transverse cylinder 2022. A second mounting plate 2023 is fixedly connected above the first mounting plate 2021, and a positioning fixture 201 is fixedly mounted on the second mounting plate 2023. A vertically mounted disassembly / assembly electric cylinder 2024 is fixedly mounted below the first mounting plate 2021, and the output end of the disassembly / assembly electric cylinder 2024 passes upward through the bottom wall of the first mounting plate 2021, the second mounting plate 2023, and the positioning fixture 201 in sequence. A locking cylinder 2025 is horizontally fixedly connected to the output end of the disassembly / assembly electric cylinder 2024, and a locking block 2026 is fixedly connected to the output end of the locking cylinder 2025. The locking block 2026 engages with the core of the insert.

[0041] In practice, the bottom of the insert's core is provided with a T-slot or dovetail groove, and the top of the locking block 2026 has a structure that matches the T-slot or dovetail groove. After the locking cylinder 2025 drives the locking block 2026 to slide into the T-slot or dovetail groove, the locking block 2026 and the insert's core become a whole. The disassembly and assembly electric cylinder 2024 retracts, causing the locking block 2026 and the insert's core to move downwards; the disassembly and assembly electric cylinder 2024 extends, causing the locking block 2026 and the insert's core to move upwards.

[0042] A pressure block 204 is fixedly installed on the main mounting base 1, and the bottom of the pressure block 204 mates with the top of the insert. The transverse cylinder 2022 drives the first mounting plate 2021 to move directly below the pressure block 204. The disassembly and assembly electric cylinder 2024 extends, causing the core of the insert to move upward. After the core and corners of the insert abut against the pressure block 204, it moves laterally back to its original position.

[0043] In this embodiment, the ejection assembly 203 includes multiple ejection cylinders, the output ends of which engage with the corner portions of the insert. The ejection cylinders are used to push each corner portion toward the core of the insert.

[0044] In this embodiment, the main mounting base 1 is provided with a pin removal and installation mechanism 3. The pin removal and installation mechanism 3 includes a pin removal tool 301 fixedly installed above the main mounting base 1. A pin removal cylinder 302 is fixedly installed on one side of the pin removal tool 301. A pin removal pin 303 is fixedly connected to the output end of the pin removal cylinder 302. The pin removal pin 303 cooperates with the pin of the insert.

[0045] On the other side of the disassembly tool 301, an assembly cylinder 304 and a storage block 306 are fixedly installed. An assembly pin 305 is fixedly connected to the output end of the assembly cylinder 304. The storage block 306 has a storage hole through it. After the assembly pin 305 slides through the storage hole, it cooperates with the pin of the insert. The storage hole can not only store the removed pin, but also guide the assembly pin 305 to make its movement trajectory more accurate.

[0046] To prevent the core from moving up and down arbitrarily, the frame and the core are connected by pins. For example... Figure 7 As shown, when removing the pin, the pin-removing cylinder 302 retracts, causing the pin-removing ejector pin 303 to move to the left until the pin is completely pushed out of the insert and into the storage hole. Then, the pin-removing cylinder 302 extends and causes the pin-removing ejector pin 303 to withdraw from the insert. At this time, the core of the insert can move up and down, thus allowing the insert to be removed.

[0047] When installing the pin, the assembly cylinder 304 retracts, driving the assembly ejector pin 305 to move to the right until the pin is fully pushed into the insert. After that, the core of the insert can no longer move up and down, and the insert assembly is complete.

[0048] In this embodiment, a heating fixture 4 is fixedly provided on the main mounting base 1, and an electric heating tube 401 is connected inside the heating fixture 4. The heating fixture 4 is used to keep the insert warm.

[0049] Because the insert needs to be heated to a certain temperature inside the mold for proper injection molding, its temperature drops rapidly after being removed from the mold. When the insert is reinserted into the mold, it needs to be reheated to reach the predetermined temperature. The electric heating element 401 heats the insert, preventing its temperature from dropping too quickly and reducing the time required for reheating after it is returned to the mold, thereby improving production efficiency.

[0050] In this embodiment, the main mounting base 1 is slidably provided with a loading fixture 5 and a unloading fixture 6 for carrying the insert. Both the loading fixture 5 and the unloading fixture 6 are driven to move by a rodless cylinder.

[0051] In this embodiment, the main mounting base 1 is provided with a cleaning mechanism 7, which includes a housing 701. The top, side walls, and bottom of the housing 701 are all provided with openings, and a cleaning assembly 702 is provided inside the housing 701. The cleaning mechanism 7 is used to remove residual resin from the surface of the insert.

[0052] The cleaning assembly 702 includes a third mounting plate 7021 horizontally fixedly mounted on the main mounting base 1. A fourth mounting plate 7022 is vertically fixedly mounted on the bottom of the third mounting plate 7021. A lifting cylinder 7023 is horizontally slidably connected to the fourth mounting plate 7022. The output end of the lifting cylinder 7023 passes through the third mounting plate 7021 upwards. A first motor 7024 is fixedly mounted on the output end of the lifting cylinder 7023. A first pulley is fixedly connected to the output end of the first motor 7024. A cleaning fixture 7027 is rotatably connected to the output end of the lifting cylinder 7023. A second pulley is fixedly mounted on the bottom of the cleaning fixture 7027. The first pulley and the second pulley are connected by a belt.

[0053] The lifting cylinder 7023 is fixedly equipped with a jet telescopic cylinder 7025 on both sides opposite to it. The output end of the jet telescopic cylinder 7025 is equipped with a jet nozzle 7026. The position of the air outlet of the jet nozzle 7026 corresponds to the position of the cleaning fixture 7027.

[0054] In use, the lifting cylinder 7023 extends upward and beyond the top opening. After the insert is placed into the cleaning fixture 7027, the lifting cylinder 7023 retracts back into the housing 701. The jet telescopic cylinder 7025 drives the jet nozzle 7026 to approach the insert. The jet nozzle 7026 is connected to an air compressor or other air compression equipment and sprays high-pressure airflow onto the surface of the insert. The first motor 7024 drives the cleaning fixture 7027 to rotate. Under the impact of the high-pressure airflow, the residual resin on various parts of the insert surface is cleaned.

[0055] In this embodiment, the top opening of the housing 701 is provided with a horizontally sliding top door 7011, which is driven by a top door cylinder. The side wall opening of the housing 701 is provided with a vertically sliding front door 7012, which is driven by a front door cylinder. Both the top door 7011 and the front door 7012 serve a protective function and can prevent the resin being cleaned from splashing. Cleaning components 7028 are also provided on both sides of the side wall opening. The installation position of the cleaning components 7028 corresponds to the installation position of the cleaning assembly 702. Specifically, the cleaning components 7028 are brush blades installed on both sides of the side wall opening. When the lifting cylinder 7023 and the cleaning fixture 7027 slide out from the side wall opening, the cleaning components 7028 clean the resin adhering to the surface, preventing it from affecting the cleanliness of the working environment.

[0056] In this embodiment, the handling mechanism 8 is mounted on the main mounting base 1. It can be a three-axis manipulator composed of an X-axis linear module, a Y-axis linear module, and a Z-axis linear module, which are widely used in the prior art, or a multi-axis industrial robot arm, etc. It can drive the insert and injection molded products to flow between different processes by connecting pneumatic grippers or suction cups.

[0057] In this embodiment, multiple inserts are removed from the mold and placed in the corresponding heating fixture 4 for heat preservation. The conveying mechanism 8 moves the inserts between the heating fixture 4, the pin removal and installation mechanism 3, the insert removal and installation mechanism 2, the cleaning mechanism 7, the unloading fixture 6, and the loading fixture 5. The main workflow is as follows: removing the pins, disassembling the insert core and corners, removing the injection-molded semi-finished product, cleaning the insert surface, reinstalling the insert core and corners, and installing the pins. The insert is then installed back into the mold for injection molding, and this cycle continues.

[0058] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model.
