DETAILED DESCRIPTION

[0020] The following will be described in detail with reference to the accompanying drawings. Figures 1-4 The application is further described in detail.

[0021] The embodiment of the application discloses an automatic material placing device for injection molding parts.

[0022] Referring to Figure 1 An automatic material placing device for injection molding parts is used for clamping and placing the injection molding parts after heat cutting treatment into a material tray. The device comprises a mounting platform 1 and a mounting plate 2 slidingly arranged on the mounting platform 1. A clamping mechanism 3 is arranged on the mounting plate 2, and the clamping mechanism 3 is slidingly connected with the mounting plate 2 in the horizontal direction. Specifically, a horizontal displacement cylinder is arranged on the mounting plate 2 to drive the clamping mechanism 3 to move horizontally.

[0023] Referring to Figure 2 Specifically, the clamping mechanism 3 comprises a positioning plate 31 slidingly connected with the mounting plate 2, a slide cylinder 32 arranged on the positioning plate 31 in the vertical direction, and a guide plate 33 arranged on the displacement end of the slide cylinder 32. An extension plate 34 is arranged on the guide plate 33, and a connecting block 38 is arranged on the lower side of the end of the extension plate 34 away from the guide plate 33. A two-way cylinder 35 is arranged on the connecting block 38, and a sliding seat 36 is fixedly arranged on the end of the two-way cylinder 35 away from the connecting block 38. A sliding groove 361 is formed in the end of the sliding seat 36 in the extension direction, and two clamping rods 37 for clamping the injection molding parts and driven by the two-way cylinder 35 are symmetrically arranged in the sliding groove 361.

[0024] Referring to Figure 2 The clamping rod 37 comprises an integral vertical rod part 371 and a short rod part 372 arranged on the end of the vertical rod part 371 away from the sliding seat 36, and the short rod part 372 is arranged on the side of the two vertical rod parts 371 close to each other, so as to completely clamp the injection molding parts and prevent the injection molding parts from falling during the movement of the device.

[0025] It is worth mentioning that the extension plate 34 is used to make the injection molding parts away from the slide cylinder 32 during clamping, so as to avoid collision of the injection molding parts and damage, and play a protection role.

[0026] Referring toFigure 1 And Figure 2 The rotating driving part 4 is arranged between the extension plate 34 and the connecting block 38, so that the injection molded part can be rotated, and the clamping and the material placing operation are more flexible.

[0027] Referring to Figure 3 Further, the guide plate 33 is provided with a guide groove 331 penetrating in the direction of the cylinder slide table movement, and the cylinder is provided with an elastic guide belt 332, which is slidingly arranged in the guide groove 331. When the guide plate 33 slides, the guide belt 332 slides in the guide groove 331, which limits the guide plate 33 and avoids the left and right shaking of the guide plate 33. When the guide plate 33 stops sliding, the guide belt 332 can quickly stop the guide plate 33, which is beneficial to the quick response of the guide plate 33.

[0028] Referring to Figure 3 And Figure 4 The guide plate 33 is connected with the induction stop mechanism 5, which includes a plurality of infrared induction elements 51 detachably arranged on one side of the cylinder and a baffle 52 fixedly arranged on the guide plate 33. The infrared induction element 51 includes two spaced-apart induction plates 511, and the baffle 52 is slidingly arranged between the two induction plates 511. When the baffle 52 moves vertically between the two induction plates 511 of different infrared induction elements 51, the infrared induction element 51 sends an electrical signal to stop the slide cylinder 32, so that the clamping rod 37 clamps or releases the injection molded part.

[0029] It should be noted that the function of the induction stop mechanism 5 is to quickly confirm the current height of the clamping rod 37, so as to accurately control the clamping and placing of the clamping rod 37.

[0030] Referring to Figure 3 The top end of the slide cylinder 32 is provided with a water tank 6, and the water tank 6 is provided with a water spraying pipe 61 close to the extension plate 34 and a water filling pipe 62 above the water spraying pipe 61. The purpose of arranging the water tank 6 is to cool the injection molded part to avoid adhesion with the clamping rod 37 or the tray.

[0031] The implementation principle of the automatic material placing device for injection molded parts in the embodiment is as follows:

[0032] The clamping mechanism 3 driven by the mounting plate 2 clamps the injection molded part after hot cutting through the rotating seat and the clamping rod 37, and then the water in the water tank 6 is sprayed to cool the injection molded part, helping the position on the injection molded part to quickly harden.

[0033] When the injection molded part cools down, the clamping rod 37 moves the injection molded part and finally places it into the groove on the tray.

[0034] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
