[0037] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0038] The present invention provides an automobile parts injection molding device with detachable and replaceable molds, which can ensure that the upper and lower molds are located on the same horizontal line to complete mold closing even when errors occur in the installation positions of the upper and lower molds, thereby preventing the injection molding effect from being affected by mold position deviation.

[0039] Example 1

[0041] A receiving groove 110 is provided on the top of the operating table 100 . In the initial state, the lower clamping plate 520 is located inside the receiving groove 110 and does not affect the forward and backward movement of the upper mold 220 and the closing of the lower mold 310 b .

[0042] The sliding table 200 is slidably connected to the top of the operating table 100 and is located on the left side of the accommodating groove 110. The side wall of the sliding table 200 is slidably connected to the first mounting plate 210. The side wall of the first mounting plate 210 is connected to the upper mold 220. The upper mold 220 is detachably connected to the side wall of the first mounting plate 210 and can move up and down on the side wall of the sliding table 200 along with the first mounting plate 210.

[0043] The rotating working assembly 300 includes a rotating table 310 rotatably connected to the top of the operating table 100 and located on the right side of the accommodating groove 110, and a linkage part 320 installed on the side wall of the operating table 100.

The lower mold 310b is detachably connected to the side wall of the second mounting plate 310a and can move up and down on the side wall of the rotating table 310 with the second mounting plate 310a. Each time the mold is closed, the front lower mold 310b is closed with the upper mold 220 for injection molding, and the rear lower mold 310b is used to cool the profile after injection molding. Through the design of double lower molds 310b, it is possible to ensure production efficiency while extending the cooling time of the profile after injection molding during continuous production, thereby preventing problems such as cracks in the profile.

[0044] The driving assembly 400 is installed at the front end of the operating platform 100 and connected to the sliding platform 200 to drive the sliding platform 200 to move back and forth on the top of the operating platform 100.

[0045] The centering assembly 500 includes a fixing frame 510 installed on the top of the operating table 100 and two clamping plates 520 symmetrically slidably connected inside the fixing frame 510. The lower clamping plate 520 is located inside the accommodating groove 110, and the two clamping plates 520 are connected to the sliding table 200.

[0047] Combine Figure 1-Figure 3In this embodiment, a device for injecting automobile parts with a detachable and replaceable mold is provided. During the injection molding process, the driving assembly 400 is started to drive the sliding table 200 and the upper mold 220 to move backward. When the upper mold 220 moves to the inside of the fixing frame 510, the sliding table 200 drives the two clamping plates 520 to approach each other and push the upper mold 220 and the lower mold 310b to move toward the center of the fixing frame 510, centering the upper mold 220 and the lower mold 310b to prevent mold closing failure due to mold position error. After the upper mold 220 and the lower mold 310b are closed, the striking assembly 600 performs intermittent tapping on the sliding table 200 to prevent bubbles from being generated inside the upper mold 220 and the lower mold 310b due to uneven rubber filling during injection molding. When the injection molding is completed, the driving component 400 drives the sliding table 200 and the upper mold 220 to move forward, the upper mold 220 and the lower mold 310b are separated, the two clamping plates 520 move away from each other and drive the linkage part 320 to move in conjunction, and the linkage part 320 drives the rotating table 310 to rotate and swap the positions of the two lower molds 310b. The lower mold 310b after injection is rotated to the tail to cool the internal formation of the lower mold 310b.
