Specific embodiments

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.

[0023] As Figures 1 to 4 shown, a structure for preventing damage to and taking out finished products of an injection molding machine includes an injection molding machine body 101. A workbench 102 is provided on the injection molding machine body 101. A female mold 103 is opened at the upper end of the workbench 102. A lifting platform 104 is liftably connected to the injection molding machine body 101. A male mold 106 is provided at the lower end of the lifting platform 104. An injection feeding assembly 105 for assisting in injection feeding during the injection molding process is provided on the lifting platform 104. It further includes:

[0024] A material taking-out assembly provided on the workbench 102 for assisting in taking out the material after injection molding. The material taking-out assembly includes a chute 201 opened at the bottom of the female mold 103. A push rod 202 for assisting in taking out the material is slidably connected to the chute 201. An installation cavity 203 is opened inside the workbench 102. A pushing assembly for pushing the push rod 202 is provided inside the installation cavity 203;

[0025] The pushing assembly includes a lifting plate 401 provided inside the installation cavity 203. A lifting assembly for lifting the lifting plate 401 is provided inside the installation cavity 203. A mounting plate 402 is provided above the lifting plate 401. One end of the push rod 202 is fixed to the mounting plate 402. An elastic force assembly connected by elastic force is provided between the lifting plate 401 and the mounting plate 402. A knocking assembly for knocking the mounting plate 402 when the material discharge is blocked is provided on the mounting plate 402; By driving the lifting plate 401 to move upward through the lifting assembly, during the upward movement of the lifting plate 401, the mounting plate 402 and the push rod 202 on the mounting plate 402 are driven to move upward through the elastic force assembly. During the upward movement of the push rod 202, the upper end of the push rod 202 abuts against the formed material inside the female mold 103 to push the material, assisting in the material taking-out operation of the formed material;

[0026] It should be noted here that after the injection molding machine completes injection molding, through the mutual cooperation of the material extraction component and the pushing component, the material extraction operation of the auxiliary molded material is assisted. During the discharging process, when the separation of the pushed material is blocked, through transmission, the push rod 202 can be pushed to resist the material with a greater force, facilitating the normal separation and demolding operation of the material. At the same time, the vibration effect can also assist the rapid separation and demolding operation of the blocked material, preventing the material from being continuously extruded and pushed after being blocked, which may cause damage to the material, and ensuring the injection processing quality of the injection molding machine for the material.

[0027] The elastic component includes multiple sets of sleeves 601 fixed to the lower end of the mounting plate 402. A sliding rod 602 is slidably connected to the sleeve 601. One end of the sliding rod 602 is fixed to the lifting plate 401. A spring 603 is sleeved outside each set of sleeves 601. The two ends of the spring 603 are respectively connected to the lifting plate 401 and the mounting plate 402. During the process of pushing and extracting materials, when the separation of the pushed material is blocked, the movement of the push rod 202 and the mounting plate 402 is limited by the material. As the lifting plate 401 continues to move, the lifting plate 401 moves towards the mounting plate 402 in a contracting manner. During the movement process, each sliding rod 602 is pushed to slide on each sleeve 601, and the spring 603 is deformed by force to generate elastic force. Through the elastic force of the spring 603, the push rod 202 on the mounting plate 402 is pushed to resist the material with a greater force, facilitating the normal separation and demolding operation of the material.

[0028] Two sets of knocking components are symmetrically arranged below the mounting plate 402. The knocking component includes a driving disk 701 arranged below the mounting plate 402. Rubber protrusions 702 for pushing against the mounting plate 402 are fixed around the driving disk 701. A rotating component for rotating the driving disk 701 is arranged on the mounting plate 402. The rotating component includes two sets of support frames 801 fixed to the lower end of the mounting plate 402. A rotating shaft 802 is rotatably connected to the support frames 801. The driving disks 701 of the two sets of knocking components are respectively fixed to both ends of the rotating shaft 802. A transmission component for transmitting power to the rotating shaft 802 is arranged between the rotating shaft 802 and the lifting plate 401. Through the transmission component, the rotating shaft 802 is driven to rotate on the support frames 801. During the rotation process, the driving disk 701 is driven to rotate. During the rotation process of the driving disk 701, each rubber protrusion 702 is driven to sequentially push against the mounting plate 402, causing the mounting plate 402, the push rod 202, and the resisted material to vibrate. Through the vibration effect, the rapid separation and demolding operation of the blocked material is assisted.

[0029] The transmission assembly includes a gear 901 fixed on a rotating shaft 802, and a rack 902 for meshing and driving with the gear 901 is fixed on the lifting plate 401; during the process of the lifting plate 401 shrinking and moving towards the mounting plate 402, the rack 902 is driven to rotate. During the movement of the rack 902, through the meshing transmission between the rack 902 and the gear 901, the rotating shaft 802 is driven to rotate on the support frame 801.

[0030] The lifting assembly includes a fixing frame 501 fixed inside the installation cavity 203, and a cylinder 502 for driving the lifting of the lifting plate 401 is installed on the fixing frame 501; through the cylinder 502 on the fixing frame 501, it is convenient to assist the lifting movement of the lifting plate 401.

[0031] During the processing of the injection molding machine, the injection molding machine body 101 drives the lifting table 104 to descend, so that the punch 106 moves into the inside of the die 103. After the descending movement, through the injection function of the injection material assembly 105 and the forming function of the punch 106 and the die 103, the injection molding of the material is completed;

[0032] After the material is injection molded, the lifting assembly drives the lifting plate 401 to move upward. During the upward movement of the lifting plate 401, the mounting plate 402 and the push rod 202 on the mounting plate 402 are driven to move upward through the elastic force assembly. During the upward movement of the push rod 202, the upper end of the push rod 202 abuts against the formed material inside the die 103, pushing the material to assist the material taking operation of the formed material;

[0033] During the process of pushing and taking the material, when the separation of the pushed material is blocked, the movement of the push rod 202 and the mounting plate 402 is limited by the material. As the lifting plate 401 continues to move, the lifting plate 401 shrinks and moves towards the mounting plate 402. During the movement, each group of sliding rods 602 are respectively pushed to slide on each group of sleeves 601 and the spring 603 is deformed by force to generate elastic force. Through the elastic force of the spring 603, the push rod 202 on the mounting plate 402 abuts against the material with a greater force, which is convenient to assist the normal separation and demoulding operation of the material. And during the process of the lifting plate 401 shrinking and moving towards the mounting plate 402, the rack 902 is driven to rotate. During the movement of the rack 902, through the meshing transmission between the rack 902 and the gear 901, the rotating shaft 802 is driven to rotate on the support frame 801. During the rotation process, the driving disc 701 is driven to rotate. During the rotation of the driving disc 701, each group of rubber protrusions 702 are driven to abut against the mounting plate 402 in turn, causing the mounting plate 402, the push rod 202 and the blocked material to vibrate. Through the vibration effect, the rapid separation and demoulding operation of the blocked material is assisted, preventing the material from being continuously squeezed and pushed after being blocked, which may cause damage to the material, and ensuring the injection processing quality of the injection molding machine for the material.
