Description

Technical Field

[0001] This utility model relates to the technical field of material leakage devices, specifically a material leakage device that does not require drying and overflows. Background Technology

[0002] During injection molding, due to factors such as mold wear, insufficient clamping force, excessive injection pressure, or poor fit between the nozzle and the mold sprue bushing, flash (also known as burrs or leaks) often occurs at the mold parting surface, slide block position, or nozzle. This flash is usually in the form of filaments or small flakes of high-temperature molten plastic.

[0003] Currently, there are two main ways to handle these spills: one is to let them fall onto the ground or equipment platform and be cleaned regularly by operators after cooling; the other is to place a simple receiving tray under the mold. The first method leads to a dirty and messy working environment, and the cooled plastic fragments are difficult to clean up and may be crushed and contaminate other areas, posing safety hazards and fire risks. Although the second method can collect the materials in a centralized manner, the materials in the receiving tray are still exposed to the air, and the different colored strips are mixed together and may be contaminated with oil and dust, resulting in a decrease in recycling value. If they are to be reused, they must go through multiple processes such as crushing, washing, and drying, which is costly. Therefore, most of them are treated as waste, resulting in the waste of raw materials.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a drying-free overflow leakage device to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0005] The purpose of this invention is to provide a drying-free overflow leakage device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a material overflow and leakage device without drying, comprising: an injection molding machine body and an overflow collection device disposed on the injection molding machine body;

[0007] The overflow collection device includes:

[0008] The overflow receiving and guiding section is located below the mold parting surface and the nozzle area to receive the overflowing high-temperature molten material;

[0009] The heat preservation unit is located in the overflow receiving and guiding part and is used to heat and preserve the material.

[0010] The mounting base is fixed inside the injection molding machine body and located below the overflow receiving and guiding part;

[0011] The cooling and solidification module is movably mounted on the mounting base;

[0012] At least one solidified material receiving body can be placed inside the cooling and solidification module;

[0013] The bottom of the overflow receiving and guiding part is provided with an outlet, and the top of the condensate collection body is provided with an inlet. The outlet and the inlet are positioned correspondingly above and below each other.

[0014] The cooling and solidification module can cool the solidified material container so that the molten material flowing into it solidifies and takes shape.

[0015] Specifically, the overflow receiving and guiding section located below the mold parting surface and nozzle area automatically receives the high-temperature molten material, and its heat preservation unit heats and keeps the molten material in a flowing state. The molten material then flows through the outlet into the inlet of the solidified material collection body below. The cooling and solidification module cools the solidified material collection body, causing the molten material to quickly solidify and form within it. This device achieves automatic, centralized, and closed collection of overflow, avoiding pollution and safety hazards. At the same time, it directly obtains clean and regular solidified material blocks, eliminating the complex recycling processes such as crushing, washing, and drying required by traditional methods, significantly reducing processing costs and raw material waste.

[0016] Preferably, the connection between the cooling and solidification module and the mounting base is a hinge.

[0017] Specifically, the hinged design allows the cooling and solidification module to flip open outwards like a door, greatly facilitating operators to approach, retrieve, and clean the heavy solidified material storage unit from the side of the injection molding machine's operating door. At the same time, when closed, it can accurately position itself to ensure that the discharge port and the inlet are strictly aligned, effectively improving the convenience, safety, and work efficiency of operation.

[0018] Preferably, the solidified material receiving body has one or more cavities inside for shaping the molten material, and the longitudinal cross-sectional shape of the cavity is a frustum-shaped cone or a column of equal diameter that gradually narrows from top to bottom.

[0019] Specifically, by setting one or more frustoconical or cylindrical cavities within the slag collection body, a regular shaping space is provided for the molten material, allowing it to cool and form a regular and compact ingot or columnar slag. This uniform shape greatly facilitates subsequent collection, handling, storage, and direct feeding into a crusher for recycling, avoiding the drawbacks of traditional flaky or filamentous overflows that are loose, bulky, and difficult to handle, thus significantly improving the efficiency and economic benefits of recycling operations.

[0020] Preferably, the cavity is open from top to bottom, and the bottom of the solidified material receiving body is provided with an openable and closable sealing base plate.

[0021] Specifically, when it is necessary to remove the solidified ingot, simply open the sealing bottom plate, and the ingot can be completely and smoothly removed from the bottom opening of the cavity by gravity or a slight ejection force. This greatly simplifies the material removal operation and avoids the damage or difficulties that may be caused by taking it out from the top. At the same time, the through structure is also conducive to heat dissipation and improves cooling efficiency.

[0022] Preferably, the sidewalls and / or bottom walls of the condensate container are provided with a heat dissipation structure, which is one or more combinations of through holes, through grooves or heat dissipation fins.

[0023] Specifically, a heat dissipation structure consisting of through holes, through grooves, or heat dissipation fins is provided on the side walls and / or bottom walls of the condensate collection body. This significantly increases the contact surface area between the condensate collection body and the circulating cooling water in the cooling and solidification module, greatly improving the heat exchange efficiency. This allows the high-temperature molten material flowing into the cavity to cool and solidify quickly and uniformly, effectively shortening the single collection cycle and improving collection efficiency. At the same time, this passive heat dissipation structure is simple and reliable, requiring no additional energy consumption.

[0024] Preferably, the cooling and solidification module is provided with a retainer for positioning and supporting the solidified material collection body, and the side wall of the cooling and solidification module is provided with an inlet and outlet water connector communicating with its interior.

[0025] Specifically, the retainer ensures that the solidified material collection body is fixed in position within the module and that its inlet is precisely aligned with the outlet above, preventing overflow and leakage. At the same time, the inlet and outlet water connectors can be connected to an external circulating cooling system, allowing the coolant to continuously flow within the module and efficiently remove the heat from the solidified material collection body and its internal molten material. This achieves forced, uniform, and rapid cooling and solidification, significantly improving processing efficiency and the quality of the recycled ingots.

[0026] Preferably, the cooling and solidification module has a handle on the side adjacent to the injection molding machine's operating door.

[0027] Specifically, it provides operators with a direct, labor-saving, and safe point of force application, allowing them to easily and stably pull or flip the module without having to probe into the equipment or contact the high-temperature surface. This enables them to safely and efficiently complete the loading and unloading of the condensate collection body or the maintenance and inspection of the entire overflow collection device, greatly improving operational convenience and personnel safety.

[0028] Preferably, the heat preservation unit is an electric heating sleeve, heating belt, or heating plate that covers or is attached to the outer surface of the overflow receiving and guiding part.

[0029] Specifically, by using these mature, reliable, and easily controllable electric heating elements to uniformly and stably heat the flow guide, the heat loss of the molten material during the flow process can be effectively compensated, ensuring that it always maintains a good molten flow state. This completely prevents the plastic from solidifying and blocking the critical flow guide channel in advance, ensuring the continuity and reliability of the entire collection process from the outlet to the solidified material collection body.

[0030] Preferably, the mounting base is provided with an inclined positioning baffle on the side adjacent to the injection molding machine operating door.

[0031] Specifically, when the operator closes the cooling and solidification module, the inclined baffle naturally guides and restricts the module's movement trajectory, allowing it to automatically and accurately reach its final working position without precise alignment. Through contact with the module's side, it provides stable mechanical restraint, ensuring that the inlet of the solidified material receiving body on the module is precisely aligned with the outlet above. This effectively prevents leakage of molten material due to misalignment, while simultaneously improving operating speed and reliability.

[0032] It should be noted that the inlet of the slurry receiving body is V-shaped. The molten material discharged from the outlet of the overflow receiving and guiding part first falls on both sides of the inlet, that is, the higher parts of the two sides of the V-shape, and then fills the cavity there. After the cavities on both sides are filled, it flows towards the middle along the slope. Therefore, the cavity filling sequence is to fill from both sides to the middle step by step. When all the cavities are filled, the excess molten material will gather at the bottom of the V-shape.

[0033] Compared with the prior art, this utility model provides a drying-free overflow discharge device, which has the following beneficial effects:

[0034] By integrating automated collection, heat preservation and diversion, and rapid cooling molding functions, the traditional problem of injection molding overflow treatment has been completely solved. It not only completely eliminates raw material waste and environmental pollution on the production site, but also significantly improves operational safety and cleanliness. It directly transforms messy overflow into high-quality recycled ingots with uniform specifications and clean and dry conditions, eliminating all intermediate processing links and achieving seamless transformation from waste to raw materials. This greatly reduces the overall recycling cost and improves resource utilization. Attached Figure Description

At the same time, when closed, it can accurately position itself to ensure that the discharge port 211 and the inlet port 251 are strictly aligned, effectively improving the convenience, safety and efficiency of operation.

[0061] Preferably, the solidified material receiving body 250 has one or more cavities 252 inside for shaping the molten material, and the longitudinal cross-sectional shape of the cavity 252 is a frustum shape or a column of equal diameter that gradually narrows from top to bottom.

[0062] Specifically, by setting one or more frustoconical or cylindrical cavities 252 within the slag collection body 250, a regular shaping space is provided for the molten material, allowing it to cool and form a regular and compact ingot or columnar slag.

[0065] Preferably, the sidewalls and / or bottom walls of the condensate collection body 250 are provided with a heat dissipation structure 254, which is one or more combinations of through holes, through grooves or heat dissipation fins.

[0066] Specifically, a heat dissipation structure 254, consisting of through holes, through grooves, or heat dissipation fins, is provided on the side wall and / or bottom wall of the condensate collection body 250. This significantly increases the contact surface area between the condensate collection body 250 and the circulating cooling water in the cooling and solidification module 240, greatly improving the heat exchange efficiency.

[0075] Working principle: During the injection molding process, the high-temperature molten material overflowing from the mold parting surface or nozzle is first received by the overflow receiving and guiding part 210 below. Under the continuous heating of the heat preservation unit 220, the guiding part maintains the fluidity of the molten material. The molten material then flows into the cavity 252 of the aligned solidification collection body 250 below by gravity through the bottom outlet 211. At this time, the cooling and solidification module 240 quickly absorbs and removes heat through its internal circulating cooling system, so that the molten material is quickly cooled and solidified into a regular ingot in the solidification collection body 250. After the collection is full, the operator can flip the entire cooling and solidification module 240 outward along the hinge axis through the handle 243 to fully expose and safely and conveniently pick up and put in the solidification collection body 250, and directly obtain a clean, dry, and easily recyclable molded ingot, thereby realizing the automatic, closed, continuous collection and pretreatment of overflow.
