Description

Technical Field

[0001] This utility model relates to the technical field of plastic product processing equipment, and in particular to an LED kitchen and bathroom light housing molding equipment. Background Technology

[0002] As both an appearance and structural component, the quality of LED kitchen and bathroom light housings directly affects the product's aesthetics, sealing performance, and yield rate. Blow molding is a common process for producing hollow plastic products, but existing blow molding equipment has significant shortcomings when applied to the production of square, thin-walled kitchen and bathroom light housings, mainly in the following aspects: First, poor mold sealing leads to product molding defects. Existing equipment typically relies on the rigid clamping force of the mold itself to seal the edges of the parison. Because the parison is in a high-temperature, high-elasticity state and has slight thickness variations, rigid sealing cannot ensure uniform compression at all edges. During blow molding, high-pressure gas easily leaks from poorly sealed areas, resulting in insufficient pressure inside the cavity. This causes defects such as incomplete filling and unclear outlines in hard-to-fill areas like the corners of the lamp housing. Furthermore, excessive local material stretching can cause uneven wall thickness, affecting product strength and quality consistency.

[0003] Secondly, the crude demolding method easily causes damage to the product surface. The molded lamp housing is difficult to separate from the mold base plate due to vacuum adhesion or slight material adhesion. Currently, manual prying or simple mechanical ejection methods are commonly used. This easily causes irreversible damage such as scratches and deformation, reducing the product yield and commercial value.

[0004] Third, the equipment has a single function and lacks flexible and intelligent production capabilities. Existing equipment is usually designed to perform only one function: blow molding. The mold installation angle is fixed, and there is a lack of real-time monitoring of key stations such as mold closing and blow molding during the production process. Operators cannot intuitively judge whether the parison positioning and mold sealing are good, and defects are often discovered after demolding, resulting in waste of materials and time.

[0005] Therefore, there is an urgent need for a specialized equipment designed specifically for the molding process of LED kitchen and bathroom light housings, which can effectively solve the aforementioned sealing, demolding, and intelligent issues, in order to achieve high-quality, high-efficiency, and high-yield automated production. Utility Model Content

[0006] This application provides an LED kitchen and bathroom light housing molding equipment to solve the technical problems of poor mold sealing, easy damage to products during demolding, and low yield and low production efficiency caused by lack of intelligent monitoring in existing blow molding equipment.

[0007] To achieve the above objectives, the following technical solution is provided: an LED kitchen and bathroom light housing molding equipment, comprising: An LED kitchen and bathroom light housing molding equipment includes a molding base plate, with multiple support pillars evenly distributed around its perimeter, and a blow molding opening in the center of the molding base plate. The upper ends of multiple pillars are supported by an angle adjustment component. A stamping component is installed on the angle adjustment component. The output end of the stamping component is set downward and connected to a forming component. The forming component and the forming base plate are arranged vertically opposite and parallel to each other. The molding equipment also includes a blow molding air pump, which is airtightly connected to the blow molding nozzle and is used to provide blow molding airflow into the molding component; The molding equipment also includes a lifting assembly, which is located on the upper surface of the molding base plate and is used to separate the molded finished part from the molding base plate.

[0008] Furthermore, the angle adjustment component includes a fixed support foot fixedly mounted on the side of the support column, a stud rotatably mounted on the fixed support foot, and a top plate threaded onto the upper end of the stud.

[0009] Furthermore, the stamping assembly includes a hydraulic cylinder fixedly disposed in the middle of the top plate. The piston rod of the hydraulic cylinder extends downward and an end plate is fixedly disposed at its end. Guide rods are also evenly distributed between the end plate and the top plate. The lower end of the guide rods is fixedly connected to the end plate. A slot for inserting the forming assembly is horizontally opened at the lower end of the end plate.

[0010] Furthermore, the molding component includes a mold, the upper end of which is horizontally provided with a dovetail block that mates with a slot, the dovetail block being slidably embedded in the slot.

[0011] Furthermore, a flexible pressing element is provided around the lower opening of the mold. When the stamping assembly drives the mold to press down, the flexible pressing element is used to seal and press the edge of the blank located between the mold and the forming base plate.

[0012] Furthermore, the material lifting assembly includes a spiral groove fixedly mounted on the upper surface of the forming base plate, a slider slidably mounted inside the spiral groove, and a material lifting knife fixedly mounted on the side of the slider.

[0013] Furthermore, ball bearings are provided between the contact surfaces of the slider and the spiral groove.

[0014] Furthermore, a lifting cylinder is connected to one side of the slider. The cylinder body of the lifting cylinder is fixedly mounted on the forming base plate, and the piston rod of the lifting cylinder is connected to the slider to drive the slider to slide along the loop groove.

[0015] Furthermore, the molding equipment also has an observation module, which includes a camera fixedly mounted in the middle of the support column by a bracket, and a display screen mounted on the outside of the equipment. The signal output terminal of the camera is electrically connected to the signal input terminal of the display screen.

[0016] Furthermore, at least four guide rods are provided, and they are symmetrically distributed around the hydraulic cylinder.

[0017] The beneficial effects of this utility model are: This application utilizes an angle adjustment component for precise calibration of the mold's levelness, combined with a flexible sealing ring at the lower end of the molding component, to effectively improve the parallelism and sealing of the mold closing mechanism. The flexible sealing ring can adaptively compensate for minor differences in preform thickness and deviations in the flatness of the base plate, reducing the risk of high-pressure gas leakage during blow molding. This helps ensure stable cavity pressure, allowing material to fully fill the mold corners, thereby improving the uniformity of product wall thickness, the clarity of the outline, and the overall structural strength, ensuring consistent product molding quality and a high yield rate.

[0018] The ejector assembly employs a uniform force application method from the periphery of the product. A cylinder-driven ejector blade slides smoothly along a predetermined path, gradually breaking the adhesion between the product and the base plate using shearing force. This avoids the surface scratches, indentations, or deformation that can occur with traditional ejection methods due to concentrated stress. It reduces the risk of damage to the smooth surface of the product during demolding, ensuring the commercial value of the LED lamp housing as an aesthetic component.

[0019] The observation module monitors the mold-closing area in real time via a camera and transmits the images to an external display screen. Operators can remotely and intuitively monitor the placement, alignment, and sealing status of the preform, facilitating timely detection and correction of pre-production anomalies. This reduces waste and scrap caused by incorrect material preparation or poor alignment, improving the controllability of the production process, the success rate of first-time molding, and the level of intelligent production.

[0020] The molds are quickly changed via a dovetail groove mechanism, enhancing the equipment's flexibility in adapting to the production of different product models. Meanwhile, the automated process, from automatic mold closing and blow molding to non-destructive material removal, reduces manual intervention, improves production continuity and efficiency, and enables the equipment to better adapt to the demands of multi-variety, batch production with high quality requirements.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0025] refer to Figures 1 to 6 The LED kitchen and bathroom light housing molding equipment of this utility model mainly includes a molding base plate 10, a support column 11, an angle adjustment component 20, a stamping component 30, a molding component 40, a lifting component 50, an observation module 60, and a blow molding air pump 70.

[0026] The molding base plate 10 serves as the basic platform of the equipment, with a blow molding port 12 in its center and multiple evenly distributed support pillars 11 providing support around it. An angle adjustment assembly 20 is mounted on the upper end of the support pillars 11 to support and adjust the spatial orientation of the stamping assembly 30. The stamping assembly 30 is fixed to the angle adjustment assembly 20, and its output end is connected downwards to the molding assembly 40. The molding assembly 40 and the molding base plate 10 are arranged vertically opposite each other and parallel to each other, together forming the blow molding cavity. The blow molding air pump 70 is airtightly connected to the blow molding port 12 through a pipe, providing high-pressure airflow for preform blow molding. The material lifting assembly 50 is installed on the upper surface of the molding base plate 10 to separate the finished lamp housing from the base plate after molding. The observation module 60 provides visual monitoring of key workstations. The blow molding material in this application is a heated sheet of plastic, which, after heating, is placed on the molding base plate 10 and covers the blow molding port 12.

[0027] This application integrates angle adjustment, stamping, forming, blowing, material lifting, and observation functions into one unit, realizing an automated process from mold closing and blow molding to demolding. Its modular design is not only compact and space-saving, but also allows each functional component to work collaboratively, specifically addressing the technological challenges of lamp housing blow molding and providing a hardware foundation for improving product quality and production efficiency. Example 1

[0028] This embodiment describes in detail the connection and cooperation of the angle adjustment component 20, the stamping component 30 and the forming component 40.

[0029] refer to Figure 1 , Figure 2 , Figure 5 The angle adjustment assembly 20 includes a fixed support leg 21 fixedly mounted on the side of the support column 11. A stud 22 is rotatably mounted on the fixed support leg 21 via a bearing or bushing. The upper end of the stud 22 is threadedly connected to a top plate 23. By rotating the studs 22 at each of the four corners, the height of each corner of the top plate 23 can be independently adjusted, thereby achieving fine-tuning of its levelness.

[0030] refer to Figure 3 , Figure 4 The stamping assembly 30 includes a hydraulic cylinder 31 fixedly mounted in the middle of the top plate 23. The piston rod of the hydraulic cylinder 31 extends vertically downward, and its end is fixedly connected to an end plate 32. At least four guide rods 33 are evenly distributed between the end plate 32 and the top plate 23. The lower end of the guide rod 33 is fixedly connected to the end plate 32, and the upper end passes through a corresponding aperture on the top plate 23. A slot 43 is horizontally formed at the lower end of the end plate 32.

[0031] The molding component 40 mainly includes a mold 41, on the upper part of which a dovetail block 42 is fixedly mounted. The shape of the dovetail block 42 matches the slot 43 on the end plate 32, and it can be horizontally slidably embedded therein, realizing the quick installation and replacement of the mold 41. At the lower opening edge of the mold 41, a flexible pressing member 44 made of high-temperature resistant elastic material (such as silicone rubber) is embedded around it.

[0032] The technical advantages of this solution are as follows: First, the angle adjustment mechanism allows for precise calibration of the mold's level, helping to reduce uneven sealing caused by non-parallel mold closing and creating conditions for subsequent uniform pressing. Second, the hydraulic drive combined with the multi-guide rod structure provides smooth and well-guided mold closing power, reducing the risk of mold misalignment and protecting the mold and parison. Third, the dovetail groove quick-change connection improves the efficiency of mold replacement and maintenance, enhancing the equipment's adaptability. Fourth, the flexible pressure component 44 is designed to elastically deform during mold closing, better adapting to micro-thickness changes in the parison and flatness deviations of the base plate, thereby forming a relatively uniform sealing band around the parison, effectively reducing the possibility of high-pressure gas leakage during blow molding and helping to improve the uniformity of product wall thickness and contour clarity. Example 2

[0033] refer to Figure 2 and Figure 6 This embodiment describes in detail the structure and operation of the material lifting component 50.

[0034] The lifting assembly 50 includes a loop groove 51 fixedly mounted on the upper surface of the forming base plate 10. A slider 52 is embedded in the loop groove 51 and can slide along it. To reduce frictional resistance, several ball bearings 55 are provided between the contact surfaces of the slider 52 and the loop groove 51. A thin-plate lifting blade 53 is fixedly mounted on the side of the slider 52. The cylinder body of the lifting cylinder 54 is fixed to the forming base plate 10, and its piston rod is connected to the slider 52, driving the slider 52 and the lifting blade 53 along the path defined by the loop groove 51.

[0035] The ejector assembly 50 provides a demolding solution that differs from traditional ejection methods. Its technological advantages are: After molding and cooling, the lamp housing easily adheres to the base plate. If it is ejected from a concentrated point or manually pried off, damage to the product surface can easily occur. This solution uses a cylinder to drive the lifting blade 53, allowing it to slide smoothly and continuously along the entire periphery of the lamp housing. The thin cutting edge of the lifting blade 53 gradually cuts into the microscopic gaps between the product and the base plate, using the shearing force of the movement to break the adhesion force relatively evenly along the periphery. This method of applying force evenly around the periphery avoids excessive stress concentration, thus greatly reducing the risk of scratches, indentations, or deformation on the lamp housing surface, helping to protect the integrity of the product's appearance and improving the yield rate of the final product. The ball bearing 55 ensures smooth sliding, reducing wear and jamming. Example 3

[0036] refer to Figure 1 This embodiment describes the setup of the observation module 60 and its coordination with the overall equipment.

[0037] The observation module 60 includes a camera 61 fixedly mounted to the middle of the support column 11 via a bracket, and a display screen 62 located outside the equipment for easy observation by the operator. The signal output terminal of the camera 61 is electrically connected to the signal input terminal of the display screen 62 via a data cable. This module is integrated into the equipment along with the aforementioned molding system and lifting system.

[0038] The technical effects of this solution are as follows: This module adds process visualization and monitoring functions to the equipment. The field of view of camera 61 covers the mold closing area, enabling real-time transmission of images of key aspects such as the placement of the preform and the mold closing process to display screen 62. This allows operators to remotely and intuitively understand the equipment's operating status, such as whether the preform is placed in place and whether the surrounding pressing is roughly uniform after mold closing. This real-time feedback mechanism helps to detect obvious anomalies before blow molding begins, allowing for timely adjustments and reducing the possibility of scrap due to poor material preparation or alignment, thus improving the controllability of the production process and the success rate of one-time molding. Simultaneously, the observation module, combined with functions such as automated material handling and rapid mold changing, further enhances the equipment's potential for intelligent and flexible production, enabling it to better adapt to the production needs of multiple varieties and high quality.

[0039] The workflow of the LED kitchen and bathroom light housing molding equipment of this utility model is as follows: 1. Preparation: Place the pre-formed plastic preform on the molding base plate 10 and cover the blow molding nozzle 12.

[0040] 2. Adjustment and Monitoring: Fine-tune the level of the upper mold using the angle adjustment component 20. Observe the position of the blank using the observation module 60.

[0041] 3. Mold closing and sealing: Start the stamping assembly 30, drive the mold 41 to press down, and the flexible pressing part 44 presses the edge of the blank to form a seal.

[0042] 4. Blow molding: High-pressure gas is injected by blow molding air pump 70, the parison expands and sticks tightly to the inner wall of mold 41, and then cools and solidifies.

[0043] 5. Mold opening and material removal: Mold 41 moves upward. Start the material removal cylinder 54 to drive the material removal knife 53 to move and pry the formed lamp housing away from the base plate.

[0044] 6. Pick up the finished product: Take away the finished product and prepare for the next cycle.

[0045] The overall technical effects are as follows: Through the coordinated design of the above systems, this utility model specifically improves several aspects of the lamp housing blow molding production process: Improved sealing: The combination of horizontal adjustment and flexible sealing helps reduce uneven mold closing and gas leakage, which has a positive impact on product quality.

[0046] The demolding process is more protective: the peripheral lifting method reduces the risk of damage to the product's appearance.

[0047] Improved operability and adaptability: Process monitoring and quick-change mold design enhance the production flexibility and process controllability of the equipment.

[0048] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
