Description

Technical Field

[0001] This utility model relates to the field of injection molding equipment technology, specifically to an injection molding equipment for an integrated automotive fuel pump housing. Background Technology

[0002] The automotive fuel pump is an important component of the engine's fuel system. It is responsible for delivering fuel from the fuel tank to the engine's fuel injection system or carburetor. The fuel pump housing is an important part of the fuel pump, mainly used to protect the internal fuel pump components. Currently, automotive fuel pump housings are usually made of corrosion-resistant materials, such as aluminum alloy or engineering plastics.

[0003] Currently, automotive fuel pump housings made of plastic are typically produced using injection molding technology. However, when using existing injection molding equipment, after injection molding is completed, the workpiece needs to be manually removed from the bottom mold. This manual unloading method not only has a low degree of automation, but also reduces unloading efficiency as workers become fatigued. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model discloses an injection molding equipment for an integrated automotive fuel pump housing, comprising a processing table 1, a slot 2 on the processing table 1, a bottom mold 3 inside the slot 2, a mold groove on the bottom mold 3, a top mold 4 above the bottom mold 3, a first lifting assembly 5 above the processing table 1, a first lifting rod connected to the top mold 4 at the output end of the first lifting assembly 5, two positioning shafts 6 symmetrically arranged at both ends of the bottom mold 3, the outer ends of the positioning shafts 6 being rotatably connected to the processing table 1 via bearings (the bearings are embedded in the inner wall of the slot 2 and are penetrated by the positioning shafts 6), a first motor 7 on one side of the processing table 1, the output end of the first motor 7 being connected to one of the positioning shafts 6;

[0024] The processing table 1 is provided with a second lifting assembly 15 below it. The output end of the second lifting assembly 15 is provided with a bent rod 16, and both ends of the bent rod 16 are provided with negative pressure suction cups 17.

[0025] The inner end of the positioning shaft 6 is provided with a positioning plate, which is fixed to both sides of the bottom mold 3 by screws. The output end of the second lifting assembly 15 is provided with a second lifting rod, and the bent rod 16 is fixed to the top of the second lifting rod by screws. The screw fixing method makes it easy to assemble the bent rod 16 and the bottom mold 3.

[0026] Two limiting components are symmetrically arranged on the upper end of the processing table 1 to the bottom mold 3. The limiting components include a positioning frame 8, a second motor 11, and two L-shaped clamping rods 9. The L-shaped clamping rods 9 limit the four corners of the bottom mold 3. The rear end of the L-shaped clamping rods 9 is provided with a support rod 10. The front end of the positioning frame 8 is provided with a second motor 11. The output end of the second motor 11 is provided with a rotating shaft 12. Two threaded rods 13 with reverse threads are symmetrically arranged on the rotating shaft 12. The two threaded rods 13 pass through the two support rods 10 and are threadedly connected to the support rods 10. The positioning frame 8 is also provided with a guide rod 14 that passes through the support rods 10 and is slidably connected to the support rods 10. The L-shaped clamping rods 9 and the support rods 10 are an integrated structure.

[0027] First, the injection molding material is injected into the mold groove of the bottom mold 3. Then, the first lifting component 5 is activated, driving the top mold 4 to descend and fit tightly against the bottom mold 3, completing the mold closing process. In the closed state, the material cools and solidifies within the mold cavity, forming the outer shell of the automotive fuel pump.

[0028] After injection molding is completed, the first lifting assembly 5 drives the top mold 4 to rise and reset, exposing the bottom mold 3. At this time, the second motor 11 is started, driving the rotating shaft 12 and the threaded rod 13 with reverse threads to rotate, causing the two L-shaped clamping rods 9 to slide in opposite directions along the guide rod 14, releasing the restriction on the four corners of the bottom mold 3.

[0029] Next, the first motor 7 is started, which drives the bottom mold 3 to rotate 180 degrees in the empty groove 2 via the positioning shaft 6, so that the mold groove opening faces downward. Then, the second lifting component 15 is started, and the bent rod 16 drives the negative pressure suction cup 17 to rise until it contacts the molded shell in the mold groove, and the negative pressure suction cup 17 starts to adsorb the shell.

[0030] The second lifting component 15 actuates again, causing the bent rod 16 to descend and remove the adsorbed fuel pump housing from the bottom mold 3 and place it in the designated position. Finally, the first motor 7 starts again, driving the bottom mold 3 back to its initial position, completing one full injection molding and unloading cycle.

[0031] Both the first motor 7 and the second motor 11 are servo motors.

[0032] The use of servo motors provides precise power control for the equipment, making the movements of each moving part more accurate and reliable, further improving the automation and stability of the entire production process, and reducing the defect rate.
