Description

Technical Field

[0001] This utility model relates to the field of mobile phone case processing technology, and in particular to a mobile phone case processing mold with anti-drop cushioning function. Background Technology

[0002] In today's mobile phone case manufacturing industry, injection molding technology is widely used. The core of this process is to heat raw materials such as plastic to a molten state and then inject them into a pre-designed mold cavity. After the raw material cools and solidifies in the cavity, the mobile phone case is initially formed. However, the formed mobile phone case needs to be removed from the mold. This process is usually accomplished by using an ejector mechanism. The ejector mechanism applies a certain force to push the formed mobile phone case out of the mold cavity.

[0003] In existing technologies, after ejection, the phone case often falls directly onto the injection molding machine. For phone cases made of brittle plastic, once they fall from a certain height onto the machine surface, they are easily damaged, potentially resulting in cracks, deformation, and other issues. These damages directly affect the quality of the phone case, making it unable to meet product quality standards and thus reducing its yield rate. A lower yield rate not only means a waste of raw materials but also increases production costs, impacting the company's economic benefits. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a mobile phone case processing mold with drop-proof and cushioning functions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mobile phone case processing mold with anti-drop cushioning function, including an injection molding bed, a fixed mold and a moving mold respectively provided on the top of the injection molding bed, an ejection mechanism provided in the inner cavity of the moving mold, a receiving cavity opened on the top of the injection molding bed, and the receiving cavity is located between the fixed mold and the moving mold, a receiving plate is slidably connected to the inner wall of the receiving cavity, and multiple sets of cushioning mechanisms are provided at the bottom of the receiving plate, the cushioning mechanism including a rotating component, the top of the rotating component being fixed to the bottom of the receiving plate, a shock-absorbing rod being rotatably connected to the bottom end of the rotating component, a damping spring shock absorber being rotatably connected to the bottom end of the shock-absorbing rod, and the damping spring shock absorber being fixed to the bottom surface of the receiving cavity.

[0006] Preferably, a conveying cavity is provided on the side of the receiving cavity. Multiple sets of drive rollers are rotatably connected to the inner wall of the conveying cavity. A conveyor belt is nested and meshed on the surface of the drive rollers. The drive rollers are driven by an external motor. In the past, after the injection molding of mobile phone cases, they were mainly collected manually. Collecting them one by one is not only time-consuming and labor-intensive, but also poses certain safety hazards. To address this problem, this utility model adopts an automatic conveying device. The mobile phone case falls into the conveyor belt after passing through the anti-drop protection mechanism. The external motor drives the drive rollers to rotate, and the drive rollers drive the conveyor belt to rotate, transporting the mobile phone case to the outside of the processing mold, reducing safety hazards and labor intensity.

[0007] Preferably, a buffer plate is provided between the conveying cavity and the receiving cavity. The buffer plate is fixedly connected to the inner wall of the receiving cavity, and the slope of the buffer plate is less than that of the receiving plate. After the phone case falls into the conveyor belt through the anti-drop protection mechanism, it is buffered a second time by the buffer plate, which further reduces the impact force received by the phone case and improves the yield rate of the phone case.

[0008] Preferably, a loading chamber is provided on the side of the conveying chamber, and a groove is formed on the inner wall of the loading chamber. A loading plate is slidably connected inside the groove. A spring is fixed between the bottom of the loading plate and the bottom surface of the loading chamber. When the phone case is conveyed by the conveyor belt, the phone case falls onto the loading plate one by one. Under the action of the spring, the loading plate gradually descends as the number of phone cases increases. When the loading plate is pressed to the lowest point, the staff collects the phone cases in a unified manner. Finally, the spring resets the loading plate. This eliminates the need for staff to collect the cases one by one, thus improving work efficiency.

[0009] Preferably, the chute is a trapezoidal groove, and the two ends of the loading plate are trapezoidal protrusions. The trapezoidal groove design improves the stability of the loading plate.

[0010] Preferably, a rotating door is rotatably connected to the side of the loading cavity. After the phone cases are loaded into the loading cavity, the staff can open the rotating door to collect the phone cases. After collection, the rotating door can be closed by a latch.

[0011] Preferably, the revolving door surface is provided with a lifting groove, which further facilitates the opening and closing of the revolving door by the staff.

[0012] Beneficial effects

[0013] In existing technologies, ejected phone cases often fall directly onto the injection molding machine. For phone cases made of brittle plastic, falling from a certain height onto the machine surface can easily cause damage, such as cracks and deformation. This damage directly affects the quality of the phone case, making it unable to meet product quality standards and thus reducing the yield rate. A lower yield rate not only means a waste of raw materials but also increases production costs, impacting the company's economic benefits. To address this issue, this invention employs a drop-proof buffer mechanism. After the phone case component is injection molded, the moving mold and fixed mold separate, and the ejection mechanism ejects the phone case. When a phone case falls onto a receiving plate, the receiving plate absorbs the pressure and transfers it to a shock-absorbing rod. The shock-absorbing rod then transfers the pressure to a damping spring shock absorber. When the spring inside the shock absorber is subjected to external impact or vibration, it undergoes compression or stretching deformation, converting the kinetic energy of the impact into elastic potential energy and storing it. When the external force disappears, the spring releases the stored energy through elastic recovery. The flow resistance of the medium inside the shock absorber or the friction of the friction plates generates a damping force in the opposite direction of motion. The damper converts the kinetic energy released by the spring into heat energy, thereby quickly dissipating the vibration energy, offsetting the impact force of the phone case, preventing cracks and deformation of the phone case, and improving its yield rate.

[0021] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:

[0024] Reference Figure 1-5 A mobile phone case processing mold with anti-drop cushioning function includes an injection molding bed 1. The top of the injection molding bed 1 is respectively provided with a fixed mold 2 and a moving mold 3. The inner cavity of the moving mold 3 is provided with an ejection mechanism 4. The top of the injection molding bed 1 is provided with a receiving cavity, which is located between the fixed mold 2 and the moving mold 3. The inner wall of the receiving cavity is slidably connected to a receiving plate 5. The bottom of the receiving plate 5 is provided with multiple sets of cushioning mechanisms. The cushioning mechanism includes a rotating part 6. The top of the rotating part 6 is fixed to the bottom of the receiving plate 5. The bottom end of the rotating part 6 is rotatably connected to a shock-absorbing rod 7. The bottom end of the shock-absorbing rod 7 is rotatably connected to a damping spring shock absorber 8. The damping spring shock absorber 8 is fixed to the bottom surface of the receiving cavity.

[0025] A conveying chamber is provided on the side of the receiving cavity. Multiple sets of drive rollers 11 are rotatably connected to the inner wall of the conveying chamber. A conveyor belt 10 is nested and meshed on the surface of each drive roller 11. The drive rollers 11 are driven by an external motor. Currently, after injection molding, mobile phone cases are mainly collected manually, which is time-consuming, labor-intensive, and poses certain safety hazards. To address these issues, this invention employs an automatic conveying device. The mobile phone case falls onto the conveyor belt 10 after passing through a drop protection mechanism. The external motor drives the drive rollers 11 to rotate, which in turn drives the conveyor belt 10 to transport the mobile phone case to the outside of the processing mold, reducing safety hazards and labor intensity. A buffer plate 9 is provided between the conveying cavity and the receiving cavity. The buffer plate 9 is fixedly connected to the inner wall of the receiving cavity, and its slope is less than that of the receiving plate 5. After the mobile phone case falls onto the conveyor belt 10 after passing through the drop protection mechanism, it undergoes secondary cushioning by the buffer plate 9, further reducing the impact force received by the mobile phone case and improving the yield rate.

[0026] A loading chamber is located on the side of the conveying cavity. A chute is formed on the inner wall of the loading chamber, and a loading plate 13 is slidably connected inside the chute. A spring 14 is fixed between the bottom of the loading plate 13 and the bottom surface of the loading cavity. When the phone cases are conveyed by the conveyor belt 10, they fall sequentially onto the loading plate 13. Under the action of the spring 14, the loading plate 13 gradually descends as more phone cases are added. When the loading plate 13 is pressed to its lowest point, the phone cases are collected by staff. Finally, the spring 14 resets the loading plate 13, eliminating the need for staff to collect them one by one, thus improving work efficiency. The chute is trapezoidal, and the two ends of the loading plate 13 are trapezoidal protrusions. The trapezoidal design improves the stability of the loading plate 13. A rotating door 15 is rotatably connected to the side of the loading cavity. After the phone cases are loaded into the loading cavity, staff can open the rotating door 15 to collect them. After collection, the rotating door 15 is closed using a latch. A lifting groove is formed on the surface of the rotating door 15, further facilitating the opening and closing of the rotating door 15 by staff.

[0027] The working principle of this utility model is as follows: After the phone case assembly is injection molded, the moving mold 3 and the fixed mold 2 separate, and the ejection mechanism 4 ejects the phone case. The phone case falls onto the receiving plate 5, which absorbs the pressure and transmits it to the shock absorber 7. The shock absorber 7 then transmits the pressure to the damping spring shock absorber 8. When the spring inside the shock absorber is subjected to external impact or vibration, it will undergo compression or stretching deformation, converting the kinetic energy of the impact into elastic potential energy for storage. When the external force disappears, the spring will release the stored energy through elastic recovery. The flow resistance of the medium inside the shock absorber, such as oil or gas, or the friction of the friction plate, generates a damping force in the opposite direction of motion. The damper converts the kinetic energy released by the spring into heat energy. The phone case falls into the conveyor belt 10 after passing through the anti-drop protection mechanism. The external motor drives the drive roller 11 to rotate, and the drive roller 11 drives the conveyor belt 10 to rotate. After secondary buffering by the buffer plate 9, the phone case is transported to the loading cavity. The phone case falls sequentially onto the loading plate 13 by the conveyor belt 10. Under the action of the spring 14, the loading plate 13 gradually descends as the number of phone cases increases. When the phone cases in the loading cavity are loaded, the staff can open the rotating door 15 to collect the phone cases. After collection, the rotating door 15 is closed by the buckle. Finally, the spring 14 resets the loading plate 13.
