Description
Technical Field
[0001] This application relates to the technical field of injection molds for intelligent device products, and particularly to an injection mold for the production of intelligent electric boxes. Background Art
[0002] An intelligent electric box is a device that facilitates the charging of electric vehicles. Electric vehicles, as a lightweight, environmentally friendly, and economical means of transportation, are widely used. Due to the limited body space of electric vehicles, their supporting batteries are generally not large, and it often takes several hours to charge once. Therefore, a large number of intelligent electric boxes need to be set up to facilitate charging. An intelligent charging station is composed of a large number of intelligent electric boxes arranged. Existing intelligent electric boxes usually consist of a socket, a protective box for waterproofing, and a socket control device. And for existing intelligent electric boxes, after the electric vehicle plug is inserted into the socket, it can be scanned by the two-dimensional code set on the intelligent electric box, and then the control device controls the socket to be powered on, thereby realizing the charging of the electric vehicle.
[0003] The material of the intelligent electric box is usually made of plastic. In order to achieve the waterproof function outdoors, it is often processed and produced in the form of injection molding, so that the product after injection molding is an integral structural form, with a good waterproof effect. In the production and manufacturing process, an injection mold for production usually needs to be processed to realize subsequent production and processing; an injection mold is a tool for producing plastic products and is also a tool for endowing plastic products with a complete structure and precise dimensions. Injection molding is a processing method used when mass-producing some complex-shaped parts. Specifically, it means that the molten plastic heated is injected into the mold cavity by a high-pressure injection molding machine, and after cooling and solidification, a formed product is obtained.
[0004] In the prior art, after the product in the electric box mold is formed, the next step is to demold the product. Due to the different structures and high requirements of different products, the designs of the mold structures are all different. It is not always easy to take the product off the mold. Practice shows that the product demolding must overcome the adhesion force and adsorption force. Among them, the adhesion force is generated after the resin matrix and the mold fitting surface are cured and formed; after the high-temperature liquid plastic is formed, the relatively high temperature of the product enables it to adsorb on the mold, which is not convenient for demolding. The temperature of the products formed by existing injection molding usually decreases by natural cooling, and the cooling speed is slow. And the staff cannot determine when the temperature can be reduced to a temperature that can be touched. Without knowing the temperature, it is easy for the staff to be scalded when touching. Summary of the Utility Model
[0005] In order to improve the efficiency of removing the injection-molded electric box products from the mold, this application provides an injection mold for the production of intelligent electric boxes.
[0006] An injection mold for the production of intelligent electric boxes provided by the present application adopts the following technical solutions:
[0007] An injection mold for the production of intelligent electric boxes includes a base, a stationary mold fixed on the base, and a moving mold slidably arranged above the stationary mold and cooperating with each other. The upper surface of the stationary mold is provided with a lower half groove, and the lower surface of the moving mold is provided with an upper half groove. The upper half groove and the lower half groove correspond to each other and form a product cavity for producing injection molded products. An injection pipe communicating with the inside of the product cavity is arranged on the moving mold. A driving component for driving the movement of the moving mold is arranged on the moving mold. A cooling component is arranged on the stationary mold. The cooling component includes a main cooling pipe arranged in a ring shape inside the stationary mold. The main cooling pipe surrounds the injection molded product, and cold water can circulate inside the main cooling pipe. A water inlet pipe and a water outlet pipe are communicated with the main cooling pipe.
[0008] By adopting the above technical solutions, when producing the injection molded products of the electric box, the molten plastic flows into the corresponding product cavity through the injection pipe and gradually forms in the product cavity. During the forming process, the cold water flowing into the main cooling pipe through the water inlet pipe is used to reduce the temperature of the stationary mold around the product cavity, so that the temperature of the stationary mold on the lower half groove gradually decreases, thereby accelerating the forming of the injection molded product and reducing the adsorption force between the injection molded product and the lower half groove, enabling the injection molded product to be quickly demolded from the stationary mold and improving the demolding efficiency. After the temperature of the cold water flowing into the main cooling pipe rises, it then flows out from the water outlet pipe, forming a flowing cold water circulation in the main cooling pipe, enabling it to cool for a long time.
[0009] Preferably, a secondary cooling pipe is also communicated with the main cooling pipe, and one end of the secondary cooling pipe points to the product to be injection molded.
[0010] By adopting the above technical solutions, the arranged secondary cooling pipe can extend towards the injection molded product, enabling it to be closer to the injection molded product, thereby more quickly reducing the temperature of the stationary mold around the injection molded product, ultimately accelerating the cooling speed of the injection molded product and enabling it to be taken off the stationary mold more quickly.
[0011] Preferably, a cooling component with the same structure as that on the stationary mold is arranged on the moving mold, and the main cooling pipe on the moving mold surrounds the upper half groove.
[0012] By adopting the above technical solutions, the cooling component arranged on the moving mold can cool the injection molded product in the upper half groove, reduce the adsorption force between the injection molded product in the upper half groove and the moving mold, and enable the injection molded product to be better demolded from the moving mold.
[0013] Preferably, an ejection assembly is provided on the stationary mold. The ejection assembly includes an ejector pin slidably disposed on the stationary mold and located at the position of the lower half groove. The upper end of the ejector pin can abut against the injection-molded product. An ejection cavity is formed inside the stationary mold and below the lower half groove. An ejection plate is vertically slidably disposed inside the ejection cavity. The lower end of the ejector pin is fixed to the ejection plate. An ejection spring is also fixed on the ejection plate. The ejection spring can be compressed in the ejection cavity, and the other end of the ejection spring is fixed to the stationary mold. When the ejection spring resets, the ejector pin ejects the injection-molded product from the lower half groove of the stationary mold.
[0014] By adopting the above technical solution, when demolding the injection-molded product from the stationary mold, the compressed ejection spring gradually resets, controlling the ejection plate to move upward in the ejection cavity, so that the ejector pin moves upward. The moving ejector pin gradually ejects the injection-molded product in the lower half groove from the lower half groove, thereby realizing the demolding of the injection-molded product from the stationary mold. Through the provided ejection assembly, the injection-molded product can be quickly demolded, avoiding the need for manual demolding by workers.
[0015] Preferably, the ejection assembly further includes a linkage cavity provided inside the stationary mold and communicating with the ejection cavity. A linkage plate is vertically slidably disposed inside the linkage cavity. The linkage plate is fixed to the ejection plate, and a linkage rod is fixed on the linkage plate. The linkage rod vertically slides through the stationary mold, and the upper end of the linkage rod can abut against the lower surface of the moving mold.
[0016] By adopting the above technical solution, during the demolding process, the linkage rod can be linked with the moving mold. When the moving mold moves away from above the stationary mold, the linkage rod gradually rises, thereby driving the ejector pin to move upward through the linkage plate, making the movement of the ejector pin cooperate with the movement of the moving mold. During the movement of the moving mold, the ejector pin gradually moves upward, ejecting the injection-molded product in the lower half groove through the ejector pin; when the moving mold moves to the stationary mold for producing the injection-molded product, the moving mold presses the linkage rod downward, causing the ejector pin in the lower half groove to gradually move downward and the ejector pin to move out of the lower half groove, allowing the molten plastic to flow normally into the lower half groove.
[0017] Preferably, the driving assembly includes a fixing plate disposed above the stationary mold and the moving mold. A plurality of connecting rods are perpendicularly fixed on the fixing plate. The other ends of the connecting rods pass through the moving mold downward and are fixed to the stationary mold. The moving mold can slide vertically along the connecting rods. A driving hydraulic cylinder for controlling the movement of the moving mold is fixed on the fixing plate.
[0018] By adopting the above technical solution, the fixed plate is fixed to the static mold and the base through the arranged connecting rods and forms an integral structure, so that the moving mold can be arranged between the static mold and the fixed plate and move along the direction of the connecting rods between the two. During the movement of the moving mold along the connecting rods, multiple connecting rods can play a guiding role, enabling the moving mold to accurately move onto the static mold, so that the upper half groove and the lower half groove are aligned and combined into a product cavity. During the movement of the moving mold, the driving hydraulic cylinder can control the rapid movement of the moving mold.
[0019] Preferably, a plurality of product cavities for producing injection molded products are arranged inside the moving mold. A flow pipe is connected between the plurality of upper half grooves on the moving mold, and the flow pipe is communicated with an injection pipe.
[0020] By adopting the above technical solution, the arranged product cavities can simultaneously process multiple injection molded products after one action of the moving mold and the static mold, improving production efficiency; the arranged flow pipe is communicated with the injection pipe, enabling the liquid plastic in the injection pipe to flow into each product cavity through the flow pipe.
[0021] Preferably, a cutting assembly is arranged on the moving mold. The cutting assembly includes a cutting plate vertically slidably arranged on the moving mold. The cutting plate is located at the position where the flow pipe is communicated with the upper half groove, and a cutting hydraulic cylinder for controlling the vertical movement of the cutting plate is arranged on the moving mold.
[0022] By adopting the above technical solution, when removing the injection molded product from the moving mold and the static mold, the cutting hydraulic cylinder controls the vertical movement of the cutting plate, and the cutting plate is controlled to cut off the connecting plastic between the flow pipe and the upper half groove, so that the injection molded product forms an individual entity, avoiding being connected and fixed to other multiple injection molded products, and enabling the individual injection molded product to better disengage from the moving mold.
[0023] Preferably, a draft angle for facilitating demolding is arranged on the peripheral groove walls of the lower half groove of the static mold, and the same draft angle is arranged on the peripheral groove walls of the upper half groove of the moving mold.
[0024] By adopting the above technical solution, the arranged draft angle can enable the injection molded product to better demold from the static mold and the moving mold during demolding, avoiding it being adsorbed on the static mold and the moving mold.
[0025] Preferably, a temperature sensor for monitoring the temperature of the injection molded product is arranged on the upper surface of the static mold and near the lower half groove. The temperature sensor is embedded in the static mold, and the injection mold further includes a controller. The temperature sensor is electrically connected to the controller, and the controller is electrically connected to the cutting hydraulic cylinder and the driving hydraulic cylinder. The controller can first control the cutting hydraulic cylinder to act and then control the driving hydraulic cylinder to act.
[0026] By adopting the above technical solution, the set temperature sensor can monitor the temperature of the static mold near the lower half groove in real time. After the temperature of the product drops to the temperature at which demolding can be carried out, the control cutting plate is controlled to cut off the connection, and then the driving hydraulic cylinder is controlled to move the moving mold away from the static mold, so as to obtain a complete injection molded product.
[0027] In summary, the present application includes at least one of the following beneficial technical effects:
[0028] 1. When processing the box body injection molded product of the intelligent electric box through this mold, the liquid plastic can flow into multiple product cavities through the injection pipe and multiple flow pipes, so that multiple injection molded products can be produced simultaneously, improving the production efficiency;
[0029] 2. During the cooling and forming process of the electric box box body product, the cooling components arranged on the moving mold and the static mold can quickly reduce the temperature of the static mold and the moving mold, thereby indirectly reducing the temperature of the injection molded product and accelerating the forming of the injection molded product, so as to facilitate the removal of the injection molded product from the moving mold and the static mold;
[0030] 3. When pouring liquid plastic into the product cavity, there will be plastic connection points between the flow pipe and the upper half groove. Through the cutting plate slidably arranged on the moving mold, before demolding the injection molded product, the plastic between the flow pipe and the injection molded product can be cut off through the set cutting plate, so as to form independent injection molded products and improve the efficiency of later demolding;
[0031] 4. After the cut electric box injection molded product needs to be removed from the static mold and the moving mold, through the set ejecting component, during the process of the moving mold moving away from the static mold and when the ejecting spring gradually returns to its original position, the ejector pin can gradually rise from the bottom of the lower half groove, so as to eject the formed product; In addition, since draft angles for facilitating demolding are provided on the groove wall of the lower half of the static mold and on the groove wall of the upper half of the moving mold, the product can be removed more quickly when demolding the product.

That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of the element can be multiple. The term "a" cannot be understood as a limitation on the number.
[0039] The following Figures 1-4 Further detailed description is made for this application.
[0040] The embodiment of this application discloses an injection mold for the production of intelligent electric boxes.
[0041] Referring to Figure 1 and Figure 2 An injection mold for the production of intelligent electric boxes includes a horizontally arranged base 1. A horizontally arranged stationary mold 2 is fixed on the base 1, and a movable mold 3 is arranged directly above the stationary mold 2. The movable mold 3 and the stationary mold 2 are arranged in parallel, and the movable mold 3 can slide vertically above the stationary mold 2 so that the lower surface of the movable mold 3 can fit onto the upper surface of the stationary mold 2. A lower half groove 21 is formed on the upper surface of the stationary mold 2, and an upper half groove 31 is formed at the corresponding position on the lower surface of the movable mold 3. When the movable mold 3 slides onto the stationary mold 2, the upper half groove 31 and the lower half groove 21 can form a product cavity for producing injection molded products. An injection tube 32 communicating with the inside of the product cavity is arranged on the movable mold 3. When using this injection mold, the movable mold 3 approaches and fits together with the stationary mold 2, and then through the arranged injection tube 32, liquid plastic is introduced into the inside of the product cavity and gradually forms, finally forming the box body injection molded product of the required intelligent electric box.
[0042] Referring to Figure 1 andFigure 2 , a driving assembly 4 for controlling the vertical movement of the moving mold 3 is provided on the moving mold 3. The driving assembly 4 includes a fixing plate 41 which is rectangular and arranged directly above the moving mold 3. The moving mold 3 can move vertically between the stationary mold 2 and the fixing plate 41. The upper end of the injection pipe 32 passes upward through the fixing plate 41. Connecting rods 42 are vertically fixed at positions near the four corners on the lower surface of the fixing plate 41. The lower ends of the connecting rods 42 pass downward through the moving mold 3 and are fixed on the stationary mold 2, enabling the moving mold 3 to move along the connecting rods 42, and the connecting rods 42 can play a guiding role. When the moving mold 3 moves, it can accurately move to the upper surface of the stationary mold 2, so that the upper half groove 31 and the lower half groove 21 can be aligned. A pair of driving hydraulic cylinders 43 are fixedly connected to the fixing plate 41. The piston rods of the two driving hydraulic cylinders 43 pass downward through the fixing plate 41 and are fixed to the moving mold 3. The vertical movement of the moving mold 3 is controlled by the provided driving hydraulic cylinders 43, enabling the moving mold 3 to open and close from the stationary mold 2.
[0043] Refer to Figure 1 and Figure 2 , a plurality of product cavities are provided between the stationary mold 2 and the moving mold 3, so that multiple injection molded products can be simultaneously manufactured during one opening and closing process of the moving mold 3 and the stationary mold 2, improving the production efficiency. Therefore, a plurality of lower half grooves 21 are evenly arranged on the upper surface of the stationary mold 2, a plurality of upper half grooves 31 are evenly arranged on the lower surface of the moving mold 3, and a plurality of flow pipes 33 are arranged between the plurality of upper half grooves 31 of the moving mold 3. The ends of the flow pipes 33 are communicated with the upper half grooves 31, and the plurality of flow pipes 33 are communicated with each other and with the injection pipe 32, allowing the liquid plastic to flow into the corresponding upper half grooves 31 through the injection pipe 32 and the flow pipes 33, so as to better fill the entire product cavity. The injection pipe 32 is vertically arranged, the lower end of the injection pipe 32 is communicated with the plurality of flow pipes 33, and the upper end of the injection pipe 32 passes upward through the moving mold 3.
[0044] Refer to Figure 3 and Figure 4, a cooling component 5 is provided on the stationary mold 2. The cooling component 5 includes a main cooling pipe 51 arranged inside the stationary mold 2 near its upper surface. The main cooling pipe 51 is annular and can surround the outside of a plurality of products to be injection-molded. At both sides of the main cooling pipe 51, a communicating water inlet pipe 52 and a water outlet pipe 53 are symmetrically arranged. By setting the water inlet pipe 52 and the water outlet pipe 53, when using this mold, cold water can be introduced into the main cooling pipe 51 to cool the stationary mold 2. When the high-temperature liquid plastic flows into the lower groove 21 and is being molded, the temperature of the mold can be reduced by cold water, thereby indirectly and quickly reducing the temperature of the plastic, enabling it to be quickly molded and improving the manufacturing efficiency. On the main cooling pipe 51 and symmetrically arranged on the inner sides at both sides thereof, there are auxiliary cooling pipes 54. The auxiliary cooling pipes 54 are communicated with the main cooling pipe 51. The ends of the auxiliary cooling pipes 54 far from the main cooling pipe 51 extend towards the injection-molded products, so that the cold water in the main cooling pipe 51 can be introduced into the auxiliary cooling pipes 54, thereby more quickly reducing the temperature of the stationary mold 2 around the products after injection molding.
[0045] Inside the moving mold 3 and near its lower surface, there is a cooling component 5 with the same structure as that on the stationary mold 2. The main cooling pipe 51 surrounds the outside of a plurality of upper grooves 31. When cooling the injection-molded products, the cooling component 5 on the moving mold 3 can cool the upper part of the products, thereby accelerating the molding speed of the transparent lampshade and improving the production efficiency.
[0046] Refer to Figure 3 and Figure 4, an ejection assembly 6 for ejecting the molded part from the lower half groove 21 of the stationary mold 2 is provided on the stationary mold 2. The ejection assembly 6 includes an ejection cavity 61 that is rectangular and disposed inside the stationary mold 2. The ejection cavity 61 is horizontally arranged and is located below a plurality of lower half grooves 21. An ejection plate 62 is vertically slidably arranged inside the ejection cavity 61. The ejection plate 62 is slidably fitted in the ejection cavity 61 and is horizontally arranged. A plurality of ejector pins 63 are perpendicularly and fixedly connected to the upper surface of the ejection plate 62. The ejector pins 63 extend vertically upward, and the upper ends of the ejector pins 63 extend into the lower half groove 21. At least two ejector pins 63 are provided in each lower half groove 21. The ejector pins 63 are correspondingly arranged at the ends of the injection molded product. When it is necessary to remove the molded product from the lower half groove 21, the vertically slidable ejection plate 62 drives the plurality of ejector pins 63 to move upward, thereby ejecting the injection molded product from the lower half groove 21. A plurality of ejection springs 64 are fixedly connected to the lower surface of the ejection plate 62 inside the ejection cavity 61. The upper ends of the ejection springs 64 are fixed to the ejection plate 62, and the lower ends are fixed to the stationary mold 2. When pouring molten plastic to be molded, the ejection springs 64 are in a compressed state, enabling the injection molded product to be normally molded in the lower half groove 21. After molding, the moving mold 3 moves away from above the stationary mold 2, the ejection springs 64 reset, and the ejection plate 62 is controlled to move upward, and the injection molded product is ejected through the ejector pins 63.
[0047] Referring to Figure 3 and Figure 4 , linkage cavities 65 are symmetrically arranged at both ends of the ejection cavity 61 inside the stationary mold 2. A linkage plate 66 is slidably fitted inside the linkage cavities 65. The linkage plate 66 is horizontally arranged and is fixed to the ejection plate 62. A linkage rod 67 is perpendicularly and fixedly connected to the linkage plate 66. The upper end of the linkage rod 67 passes through the upper surface of the stationary mold 2 upward, and the linkage rod 67 is slidably fitted with the stationary mold 2. When the moving mold 3 covers above the stationary mold 2, the upper end of the linkage rod 67 abuts against the lower surface of the moving mold 3, thereby controlling the linkage plate 66 and the ejection plate 62 to compress the ejection springs 64. The same ejection springs 64 are provided below the linkage plate 66. The length direction of the linkage rod 67 is the same as the length direction of the ejector pins 63. After the upper end of the linkage rod 67 is flush with the upper surface of the stationary mold 2, the upper ends of the ejector pins 63 are located at the bottom of the lower half groove 21, and normal injection molding can be carried out. After injection molding, and when the moving mold 3 moves away from above the stationary mold 2, the ejection springs 64 gradually reset, and can jack up the linkage plate 66 and the ejection plate 62 upward, so that the upper ends of the ejector pins 63 abut against the lower side of the injection molded product and gradually eject it from the lower half groove 21; through the provided linkage rod 67, a linkage can be formed with the ejector pins 63, so that when the moving mold 3 covers the stationary mold 2 for injection molding, the ejector pins 63 can move to the bottom of the lower half groove 21, preventing the injection molded product from being affected during molding.
[0048] Referring to Figure 3 andFigure 4 On the moving mold 3, a cutting assembly 7 is provided for cutting the plastic product at the connection between the circulation pipe 33 and the upper half groove 31. The cutting assembly 7 includes a cutting plate 71 slid vertically on the moving mold 3. The cutting plate 71 is located at the position where the circulation pipe 33 communicates with the upper half groove 31 and is close to the upper half groove 31. The upper end of the cutting plate 71 extends out from the upper surface of the moving mold 3. At a position above the moving mold 3 and close to its upper surface, a horizontal connecting plate 72 is provided. The connecting plate 72 is fixed to the upper ends of multiple cutting plates 71. By controlling the vertical movement of the connecting plate 72, the simultaneous vertical movement of multiple cutting plates 71 is controlled. The injection pipe 32 passes through the connecting plate 72. Vertically arranged cutting hydraulic cylinders 73 are fixed on the moving mold 3. There are a pair of cutting hydraulic cylinders 73, and they are arranged at positions close to both ends of the connecting plate 72. The two cutting hydraulic cylinders 73 are located below the connecting plate 72, and the upper ends of the piston rods of the cutting hydraulic cylinders 73 are fixed to the connecting plate 72. By controlling the action of the cutting hydraulic cylinders 73, the cutting plate 71 cuts the excess plastic between the circulation pipe 33 and the upper half groove 31, so that the individual injection products can be better separated from the moving mold 3.
[0049] Draft angles for facilitating demolding are provided on the groove walls of the lower half groove 21 of the stationary mold 2 and on the groove walls of the upper half groove 31 of the moving mold 3. A draft angle of 1 - 2 degrees of reducing the plastic can be adopted, and the drop is about 0.05 - 0.1 mm. By setting the draft angle, during demolding, the injection products can be better demolded from the stationary mold 2 and the moving mold 3, avoiding their adsorption on the stationary mold 2 and the moving mold 3.
[0050] Refer to Figure 3 and Figure 4 As shown in [relevant figure numbers], temperature sensors 8 embedded in the stationary mold 2 are provided on the upper surface of the stationary mold 2 and at positions close to one side of each lower half groove 21. And this injection mold further includes a controller. The controller is electrically connected to the temperature sensors 8, and the controller can be electrically connected to the cutting hydraulic cylinders 73 and the driving hydraulic cylinders 43. The staff can set the monitoring temperature of the temperature sensors 8. When the temperature around the lower half groove 21 drops below the required temperature, it proves that the injection products have been molded and cooled and can be demolded. Then a signal is transmitted to the controller, and the controller controls the cutting hydraulic cylinders 73 to cut the excess plastic on one side of the upper half groove 31, so that the injection products form individual products. Then, by controlling the driving hydraulic cylinders 43 to act through the controller, the moving mold 3 is moved away from above the stationary mold 2. During the moving-away process, the injection products in the lower half groove 21 are ejected by the ejecting assembly 6, and the injection products fall from the upper half groove 31, avoiding the need for the staff to manually remove the injection products from the product cavity and improving the efficiency of taking out the products.
[0051] The implementation principle of an injection mold for the production of intelligent electric boxes in an embodiment of this application is as follows: When producing the injection mold, the moving mold 3 is covered on the stationary mold 2, and the molten plastic flows into each product cavity through the injection pipe 32 and the circulation pipe 33 and fills the product cavity. During the molding process, the cold water flowing in the main cooling pipe 51 can reduce the temperatures of the moving mold 3 and the stationary mold 2, so as to enable the injection-molded product to quickly form and cool down. When the temperature sensor 8 monitors that the temperature is normal, the hydraulic cylinder 73 is controlled to cut off the cutting plate 71 to cut off the excess plastic, so that the injection-molded product forms an individual. When the moving mold 3 is moved away from the stationary mold 2, the ejector pin 63 automatically ejects the injection-molded product from the lower groove 21 under the action of the ejection spring 64, so as to remove the injection-molded product from the stationary mold 2.
[0052] The above is only the specific implementation manner of this application. Any person skilled in the technical field can easily think of changes or substitutions within the technical scope disclosed in this application, and all of them should be covered within the protection scope of this application. The protection scope of this application shall be subject to the protection scope of the claimed rights.
