Description

Technical Field

[0001] This invention relates to the field of polymer bottle injection molding technology, and in particular to a debris-proof polymer bottle assembly injection molding inspection and repair mechanism and method. Background Technology

[0002] The polymer bottle injection molding inspection and repair mechanism is a support device for the rapid processing of waste materials from polymer bottle injection molding. With the continuous development of technology, people's requirements for the polymer bottle injection molding inspection and repair mechanism are also getting higher and higher.

[0003] In the injection molding process of polymer bottles, injection waste typically falls freely under gravity after mold opening, which has significant drawbacks: firstly, the free fall of waste takes a long time, directly extending the injection cycle and reducing production efficiency; secondly, waste is prone to lingering and failing to fall, easily causing material jamming during mold closing, triggering equipment alarms and shutdowns, leading to production interruptions. Furthermore, residual waste easily forms debris that contaminates the product and mold, affecting molding quality and equipment lifespan. Traditional injection molding mechanisms lack active material removal, debris handling, and online detection and trimming functions, making it difficult to meet the demands of efficient, stable, and high-quality continuous production. Therefore, we propose a debris-proof polymer bottle assembly injection molding detection and trimming mechanism and method. Summary of the Invention

[0004] Technical problem solved: In view of the shortcomings of the existing technology, the present invention provides a polymer bottle assembly injection molding detection and repair mechanism and method with anti-residue, which has the advantages of active forced material ejection, rapid chip removal, short injection molding cycle, no material clamping stoppage when closing the mold, and stable product molding quality. It effectively solves the problems of slow material drop, easy retention, chip pollution and low production efficiency in traditional injection molding.

[0005] Technical Solution: To achieve the above objectives, the technical solution adopted by the present invention is as follows: a polymer bottle assembly injection molding inspection and trimming mechanism for preventing chipping, comprising a template, guide holes at all four corners of the template, an injection groove in the middle of the template, a core block on the injection groove, ejectors at all four corners of the core block, a feed inlet in the middle of the core block, an injection molding groove at the bottom of the core block, a waste trough at the lower end of the core block on the injection groove, a fixing plate assembled at the end of the template, a first cylinder positioned at the lower end of the fixing plate, a rod groove in the middle of the ejector, and a ejector rod inside the rod groove.

[0006] As a preferred technical solution of this application, the end of the ejector rod is integrally formed with a rod head, the outer wall of the ejector rod is positioned with a limiting clip and a clip frame, the clip frame is located above the limiting clip, a spring assembly is provided between the ejector rod and the rod groove, a slot is opened inside the ejector near the top of the rod groove, a positioning plate is positioned on the side of the ejector at the same plane as the slot, a micro cylinder is positioned at the end of the positioning plate, a push plate is positioned at the end of the micro cylinder, and a hook is integrally positioned at the end of the clip frame.

[0007] As a preferred technical solution of this application, the bottom of the first cylinder is connected to a connecting frame, the side of the connecting frame is positioned with a second cylinder, the end of the second cylinder is connected to a waste suction box, the bottom of the waste suction box is positioned with a motor, a vacuum cleaner is installed on the motor, a filter screen is installed inside the waste suction box above the vacuum cleaner, and a suction port is provided at the top of the waste suction box.

[0008] As a preferred technical solution of this application, the template is guided by guide holes at its four corners, the template is assembled with the core block, the core block is engaged and fixed with the feeder, and the bottom of the feeder contacts the waste trough.

[0009] As a preferred technical solution of this application, the ejector rod and the rod head are integrally formed by casting. The ejector rod moves elastically inside the rod groove through a spring assembly. When the template and core block are opened, the push plate is driven by a micro cylinder to push the position of the hook forward, thereby pushing the bracket inward to eject the ejector rod. The ejector rod is limited by a limiting clip when it is ejected.

[0010] As a preferred technical solution of this application, when the template and core block are closed, the ejector rod automatically retracts into the rod groove. At this time, the hook at the top of the card holder engages with the card groove, thereby locking the ejector rod.

[0011] As a preferred technical solution of this application, the first cylinder drives the connecting frame to move up and down, the second cylinder drives the waste suction box to move horizontally, the motor drives the vacuum cleaner to rotate at high speed to extract air, and the waste suction box is engaged and positioned with the filter screen.

[0012] A method for inspecting and repairing polymer bottle assemblies to prevent chipping during injection molding, specifically including the following steps:

[0013] S1: Injection molding: After the polymer raw material is heated and melted, it is injected into the mold cavity through the feed port, formed in the injection molding tank and cooled and solidified;

[0014] S2: Mold Opening and Demolding: The template and core block separate from the mold along the guide hole, and the molded product is demolded and removed.

[0015] S3: Forced ejection: After the mold is opened to the position, the micro cylinder in the ejector is activated, the push plate pushes the hook to release the lock of the bracket, and the spring assembly releases the elastic force to quickly extend the ejector rod and forcefully eject the residual waste material in the mold.

[0016] S4: Debris adsorption and cleaning: The first and second cylinders work together to move the waste suction box directly below the material ejection area.

[0017] S5: Mold Closure Reset: After the ejector and cleaning are completed, the mold plate and core block close the mold. The ejector rod retracts into the rod groove under the mold closing pressure. The hook engages in the groove to achieve self-locking. The ejector resets and enters the next injection cycle.

[0018] S6: Inspection and Adjustment: Real-time monitoring of material movement and adsorption effect during production.

It has the advantages of short injection molding cycle, stable production, no debris, and high molding quality, and is suitable for continuous injection molding production of polymer bottle assemblies;

[0020] Forced ejection shortens cycle time: The ejector rod actively forces the scrap material out of the mold, replacing free fall, which greatly reduces scrap cleaning time, shortens the injection molding cycle, and improves production efficiency;

[0021] No material clamping shutdown, stable production: Waste is completely removed, eliminating the occurrence of material clamping alarms and shutdowns during mold closing, ensuring continuous production;

[0022] Preventing residue contamination and improving quality: Combined with negative pressure adsorption cleaning, it thoroughly removes residue, preventing residue from adhering to products and molds, thereby improving the molding quality and appearance precision of polymer bottles;

[0040] A method for inspecting and repairing polymer bottle assemblies to prevent chipping during injection molding, specifically including the following steps:

[0041] S1: Injection molding: After the polymer raw material is heated and melted, it is injected into the mold cavity through the feed port, formed in the injection molding tank and cooled and solidified;

[0042] S2: Mold Opening and Demolding: The template and core block separate from the mold along the guide hole, and the molded product is demolded and removed.

[0043] S3: Forced ejection: After the mold is opened to the position, the micro cylinder in the ejector is activated, the push plate pushes the hook to release the lock of the bracket, and the spring assembly releases the elastic force to quickly extend the ejector rod and forcefully eject the residual waste material in the mold.

[0044] S4: Debris adsorption and cleaning: The first and second cylinders work together to move the waste suction box directly below the material ejection area. The vacuum cleaner operates at high speed to generate negative pressure, which simultaneously sucks the ejected waste and debris into the box through the suction port. The filter screen intercepts solid waste, completing the debris cleaning.

[0045] S5: Mold Closure Reset: After the ejector and cleaning are completed, the mold plate and core block close the mold. The ejector rod retracts into the rod groove under the mold closing pressure. The hook engages in the groove to achieve self-locking. The ejector resets and enters the next injection cycle.

[0046] S6: Inspection and Adjustment: Real-time monitoring of material movement and adsorption effect during production. If material is not in place or residue remains, the equipment will automatically pause and prompt for adjustment to ensure no material is stuck in the mold and no residue remains.

[0047] Working Principle: This invention includes a template 1, guide hole 2, core block 3, feed inlet 4, ejector 5, injection tank 6, waste trough 7, injection molding tank 8, fixing plate 9, first cylinder 10, spring assembly 11, clip 12, limit clip 13, rod groove 14, ejector rod 15, rod head 16, miniature cylinder 17, positioning plate 18, push plate 19, clip groove 20, clip hook 21, connecting frame 22, second cylinder 23, vacuum cleaner 24, motor 25, filter screen 26, waste suction box 27, and suction port 28. Through active ejection and negative pressure chip removal, it solves the problem of slow waste falling in traditional injection molding. This solution addresses issues such as material retention, mold clamping, and residue contamination. It boasts advantages like short injection molding cycles, stable production, no residue, and high molding quality, making it suitable for continuous injection molding production of polymer bottle assemblies. During operation, molten raw material is injected into the mold through the feed inlet 4. After mold opening, a micro-cylinder 17 drives the push plate 19 to unlock the hook 21, and a spring assembly 11 pushes the ejector rod 15 to forcefully eject waste material. The first cylinder 10 and the second cylinder 23 move the waste suction box 27 above the waste trough 7, and a vacuum cleaner 24 uses negative pressure to absorb residue. When the mold closes, the ejector rod 15 retracts under pressure, and the hook 21 engages with the slot 20 to lock, completing the cycle. The ejector 5 actively forces the waste material out, replacing the traditional free fall. Combined with the negative pressure cleaning of the waste suction box 27, this system prevents waste retention and residue buildup at the source, shortens the injection molding cycle, eliminates mold clamping stoppages, and improves production efficiency and product quality.
