Detailed Implementation

[0019] like Figures 1-4 As shown, a conformal circulating water cooling mechanism for injection molding of a large top guard plate for a four-wheeled electric vehicle includes an upper mold plate 1, a lower mold plate 2, a top guard plate forming cavity 3 disposed between the upper mold plate 1 and the lower mold plate 2, and a multi-point glue injection mechanism 4 connected to the top guard plate forming cavity 3. The multi-point glue injection mechanism 4 is disposed on the lower side of the lower mold plate 2 and connected to the bottom of the top guard plate forming cavity 3. An inclined core pulling mechanism 5 is provided on the side of the lower mold plate 2. Two sets of side inclined top components 6 are provided on the two sides of the inclined core pulling mechanism 5. The side inclined top components 6 extend from the side away from the inclined core pulling mechanism 5 to the side of the lower mold plate 2 away from the inclined core pulling mechanism 5.

[0020] In this invention, a multi-point gluing mechanism is set on the lower side of the lower template and connected to the bottom of the molding cavity, allowing gluing to enter from the non-appearance surface of the product, thus avoiding glue marks on the outer surface of the top guard plate and improving the quality of the product's outer surface. The inclined core-pulling mechanism works in conjunction with the side inclined top assembly to adapt to the complex side structure of the top guard plate, achieving smooth demolding and solving the problem of product deformation or damage that may occur with traditional demolding methods.

[0021] Specifically, the multi-point injection mechanism 4 includes a support plate 7, an injection plate 8, and a base plate 9 disposed on the lower side of the lower mold plate 2. A top plate 10 connected to the side-sloping ejector assembly 6 is disposed between the support plate 7 and the lower mold plate 2. A lifting assembly connected to the top plate 10 is also disposed on the base plate 9. The multi-point injection mechanism achieves modular assembly through the layered arrangement of the support plate, injection plate, and base plate, facilitating the installation and maintenance of each component. The top plate is connected to the side-sloping ejector assembly and the lifting assembly. The lifting assembly can drive the top plate to move the side-sloping ejector assembly, enabling the side-sloping ejector assembly to simultaneously perform ejection and side core-pulling actions during demolding, improving demolding efficiency and avoiding interference between components that could affect the demolding effect.

[0022] Specifically, a flow divider 11 is provided inside the injection molding plate 8. Several injection tubes 12 are fixedly connected to the flow divider 11. The top of each injection tube 12 vertically penetrates the support plate 7, the top plate 10, and the lower template 2, and connects to the bottom of the top guard plate molding cavity 3. The flow divider inside the injection molding plate can evenly distribute the adhesive to each injection tube, ensuring that multiple sets of injection tubes simultaneously and evenly inject adhesive into the bottom of the molding cavity, avoiding local density differences or molding defects in the product caused by uneven adhesive distribution. The vertical penetration of the injection tubes through each plate and connection to the bottom of the molding cavity ensures a stable adhesive injection path, further guaranteeing the consistency of adhesive filling and improving the molding quality of the top guard plate.

[0023] Specifically, the side-sloping ejector assembly 6 includes several sloping ejector blocks 13 arranged in a straight line. The bottom of each sloping ejector block 13 is connected to the top plate 10 via a sloping ejector rod 14. The side-sloping ejector assembly uses sloping ejector blocks arranged in a straight line, which can precisely match the shape of the side of the top guard plate, achieving full support and demolding of the product side. The sloping ejector blocks are connected to the top plate via sloping ejector rods. When the top plate moves, the sloping ejector blocks can be driven to move along a preset trajectory via the sloping ejector rods, ensuring a smooth demolding process, reducing scratches or damage to the product side, and ensuring the molding accuracy of the product side.

[0024] Specifically, the inclined core-pulling mechanism 5 includes a guide seat 15 inclinedly disposed on the side of the lower template 2 and a core-pulling seat 16 slidably disposed on the guide seat 15. The inner end of the core-pulling seat 16 is connected to the top guard plate molding cavity 3. The guide seat 15 is also provided with a core-pulling drive assembly connected to the core-pulling seat 16. The inclined core-pulling mechanism guides the core-pulling seat to slide at an incline through the guide seat, so that the inner end of the core-pulling seat can accurately adapt to the incline or complex structure of the side of the molding cavity, realizing targeted core pulling. The core-pulling drive assembly provides stable power to the core-pulling seat, ensuring that the core pulling action is timely and in place, solving the problem that traditional core-pulling mechanisms are difficult to adapt to the complex side structure of the top guard plate, and improving the molding capability of the mold for complex products.

[0025] Specifically, the core-pulling drive assembly includes two core-pulling drivers 17 that are tilted and fixed on the guide seat 15. The output shaft ends of the core-pulling drivers 17 are connected to the core-pulling seat 16. The core-pulling drive assembly uses two tilted and fixed core-pulling drivers to synchronously drive the core-pulling seat, so that the core-pulling seat is subjected to balanced force, avoiding tilting or jamming of the core-pulling seat caused by unilateral driving, and improving the stability and reliability of the core-pulling action. The dual-driver configuration enhances the driving force and can adapt to the core-pulling requirements of different specifications of top guard plates, ensuring a smooth and efficient core-pulling process.

[0026] Those skilled in the art will understand that the core-pulling actuator can be a hydraulic cylinder, a pneumatic cylinder, or a linear motor, etc.

[0027] Specifically, the guide seat 15 is further provided with several parallel guide sliders 18 with a T-shaped cross-section, and the bottom of the core-pulling seat 16 is recessed inward with a guide groove that slides in connection with the guide sliders 18. The T-shaped guide sliders on the guide seat slide in cooperation with the guide grooves at the bottom of the core-pulling seat to form a precise guiding structure, restricting the movement trajectory of the core-pulling seat and preventing the core-pulling seat from deviating or shaking during sliding; the T-shaped guide sliders can also provide longitudinal limiting to prevent the core-pulling seat from falling off, further improving the operational stability and core-pulling accuracy of the inclined core-pulling mechanism.

[0028] Specifically, the lifting assembly includes four lifting drivers 19 fixedly mounted on the base plate 9, with the output shaft ends of each lifting driver 19 connected to the top plate 10. The lifting assembly uses four lifting drivers to synchronously drive the top plate, ensuring uniform force distribution and maintaining a horizontal position during lifting. This prevents inconsistent movement of the side-tilt lifting assembly due to top plate tilting. The four drivers are distributed to provide sufficient and stable lifting force, smoothly driving the top plate and side-tilt lifting assembly to complete the demolding action, improving the reliability of the demolding process.

[0029] Those skilled in the art will understand that the lifting actuator can be a hydraulic cylinder, a pneumatic cylinder, or a linear motor, etc.

[0030] Specifically, the upper mold plate 1 and the lower mold plate 2 are also equipped with a circulating water cooling structure. The circulating water cooling structure on the upper and lower mold plates can cool the molding cavity in all directions and evenly, accelerate the cooling and molding speed of the top guard plate, and shorten the production cycle; at the same time, it can avoid product shrinkage and deformation caused by uneven cooling, improve product dimensional accuracy and molding quality, and solve the problems of low cooling efficiency or uneven cooling in traditional molds.

[0031] Specifically, the circulating water cooling structure includes several upper cooling channels 20 disposed on the upper mold plate 1 and several lower cooling channels 21 disposed on the lower mold plate 2. The circulating water cooling structure, through the separate arrangement of the upper and lower cooling channels, achieves targeted cooling of the upper and lower sides of the molding cavity, ensuring consistent cooling rates on the upper and lower surfaces of the top protective plate, further reducing product deformation caused by temperature differences. The multiple channels increase the cooling area, improve cooling efficiency, ensure rapid and uniform cooling of the top protective plate, and guarantee stable product quality.

[0032] The working principle of this utility model is as follows: the multi-point glue injection mechanism is set on the lower side of the lower template and connected to the bottom of the molding cavity, so that the glue is injected from the non-appearance surface of the product, avoiding glue marks on the outer surface of the top guard plate and improving the quality of the outer surface of the product; the inclined core pulling mechanism cooperates with the side inclined top component to adapt to the complex side structure of the top guard plate, realize smooth demolding, and solve the problem of product deformation or damage that may be caused by traditional demolding methods. The multi-point injection mechanism achieves modular assembly through the layered arrangement of support plates, injection plates, and base plates, facilitating the installation and maintenance of each component. The top plate is connected to the side-sloping ejector assembly and the lifting assembly. The lifting assembly can drive the top plate to move the side-sloping ejector assembly, enabling the side-sloping ejector assembly to simultaneously perform ejection and side core-pulling actions during demolding, improving demolding efficiency and avoiding interference between components that could affect the demolding effect. The flow divider plate in the injection plate can evenly distribute the glue to each injection tube, ensuring that multiple injection tubes inject glue synchronously and evenly to the bottom of the molding cavity, avoiding local density differences or molding defects caused by uneven glue distribution. The injection tubes vertically penetrate each plate and connect to the bottom of the molding cavity, ensuring a stable glue injection path and further guaranteeing the consistency of glue filling, thus improving the molding quality of the top guard plate. The side-mounted ejector assembly uses a linear arrangement of angled ejector blocks, which can precisely adapt to the shape of the top guard plate's side, achieving comprehensive support and demolding of the product's side. The angled ejector blocks are connected to the top plate via angled ejector rods. When the top plate moves, the angled ejector rods drive the angled ejector blocks to move along a preset trajectory, ensuring a smooth demolding process, reducing scratches or damage to the product's side, and guaranteeing the product's side molding accuracy. The angled core-pulling mechanism guides the core-pulling seat to tilt and slide through a guide seat, allowing the inner end of the core-pulling seat to precisely adapt to the tilt or complex structure of the molding cavity's side, achieving targeted core pulling. The core-pulling drive assembly provides stable power to the core-pulling seat, ensuring timely and accurate core pulling, solving the problem that traditional core-pulling mechanisms cannot adapt to the complex side structure of the top guard plate, and improving the mold's molding capability for complex products. The core-pulling drive assembly uses two tilted and fixed core-pulling drivers to synchronously drive the core-pulling seat, ensuring balanced force on the core-pulling seat and avoiding tilting of the core-pulling seat due to unilateral drive. The design incorporates a dual-drive system to enhance the stability and reliability of the core-pulling action, adapting to the core-pulling requirements of different top guard plate specifications. This ensures a smooth and efficient core-pulling process. The T-shaped guide slider on the guide seat slides in conjunction with the guide groove at the bottom of the core-pulling seat, forming a precise guiding structure that limits the movement trajectory of the core-pulling seat and prevents it from shifting or wobbling during sliding. The T-shaped guide slider also provides longitudinal limiting to prevent the core-pulling seat from falling off, further improving the operational stability and core-pulling accuracy of the inclined core-pulling mechanism. The lifting assembly uses four lifting drives to synchronously drive the top plate, ensuring even force distribution and keeping the top plate level during lifting. This prevents inconsistent movement of the side-tilting components due to top plate tilt. The four drives are distributed to provide sufficient and stable lifting force, smoothly driving the top plate and side-tilting components to complete the demolding action, improving the reliability of the demolding process. The circulating water cooling structure on the upper and lower mold plates can provide all-round and uniform cooling to the molding cavity, accelerating the cooling and molding speed of the top guard plate and shortening the production cycle. At the same time, it avoids product shrinkage and deformation caused by uneven cooling, improves product dimensional accuracy and molding quality, and solves the problems of low cooling efficiency or uneven cooling in traditional molds. The circulating water cooling structure achieves targeted cooling of the upper and lower sides of the molding cavity through the separate setting of upper and lower cooling channels, so that the cooling speed of the upper and lower surfaces of the top guard plate is consistent, further reducing product deformation caused by cooling temperature differences. The setting of multiple channels increases the cooling area, improves cooling efficiency, ensures rapid and uniform cooling of the top guard plate, and guarantees stable product quality.
