[0026] See also Figure 2-7 As shown, an embodiment of the present invention discloses a rubber shell demoulding and blanking device, including a rubber shell clamping mechanism 1, a moving mechanism 2, an overall moving mechanism 3, a discharge mechanism 4 and a receiving mechanism 5.

[0027] The rubber shell clamping mechanism 1 includes a top plate 11, a bottom plate 12, a side plate 13, an upper template 14, a lower template 15, a first cylinder 16 and a second cylinder 17. The top plate 11 and the bottom plate 12 are fixedly connected to the side plate 13 respectively, and one side of the side plate 13 is connected to the moving mechanism 2. A plurality of upper templates 14 are located below the top plate 11, and a plurality of lower templates 15 are located above the bottom plate 12. The plurality of upper templates 14 and the plurality of lower templates 15 correspond to each other one by one. The upper template 14 and the lower template 15 are respectively provided with upper positioning grooves and lower positioning grooves matching the shape of the rubber shell. The first cylinder 16 is used to drive the upper template 14 upward or downward, and the second cylinder 17 is used to drive the lower template 15 upward or downward. When the upper template 14 moving downward under the drive of the first cylinder 16 is fitted with the lower template 15 moving upward under the drive of the second cylinder 17, the upper template 14 and the lower template 15 clamp the rubber shell.

[0028] The rubber shell clamping mechanism 1 also includes an upper fixed plate 18 and a lower fixed plate 19. The cylinder bodies of the first cylinder 16 and the second cylinder 17 are respectively fixedly arranged on the top plate 11. The telescopic rod of the first cylinder 16 is fixedly connected to the upper fixed plate 18, and the telescopic rod of the second cylinder 17 is fixedly connected to the lower fixed plate 19. A plurality of upper templates 14 are fixedly connected to the lower side of the upper fixed plate 18, and a plurality of lower templates 15 are fixedly connected to the upper side of the lower fixed plate 19.

[0033] The first horizontal moving cylinder 116 drives the positioning block 119 to move forward and insert into the rubber housing, so as to position the rubber housing and prevent the rubber housing from moving forward and backward.

[0034] The moving mechanism 2 includes a cylinder mounting plate 21 and a second horizontal moving cylinder 22. The telescopic rod of the second horizontal moving cylinder 22 is hinged to the side plate 13. A guide block 23 and a guide rod 24 are fixedly arranged on the cylinder mounting plate 21.

[0035] The overall moving mechanism 3 includes a servo motor 31, a gear 32 connected to the rotating shaft of the servo motor 31, a rack 33 meshing with the gear 32, a guide rail 34 and a bracket 35. The servo motor 31 is mounted on the cylinder mounting plate 21, the bottom end surface of the cylinder mounting plate 21 is connected to the slider of the guide rail 34, and the rack 33 and the guide rail 34 are respectively fixed on the bracket 35. The servo motor 31 drives the gear 32 to rotate, and the gear 32 moves along the length direction of the rack 33, thereby driving the cylinder mounting plate 21 to move to a set position on the guide rail 34.

[0036] The unloading mechanism 4 includes a lifting cylinder 41, a connecting plate 42 and a clamping cylinder 43. The lifting cylinder 41 is vertically arranged, and the telescopic rod of the lifting cylinder 41 is fixedly connected to the connecting plate 42.

[0037] The working principle of the rubber housing demoulding and blanking device provided in the embodiment of the present invention is as follows:

[0038] After the injection mold completes product injection molding, the lower mold moves downward to the set position, and the core is located in the lower mold. The core moves horizontally with the lower mold to the set position and away from the bottom of the upper mold. Then the core escapes from the lower mold and rises to the set position. In addition, the action completed after the injection mold is completed, the overall moving mechanism 3 drives the moving mechanism 2 to move in the direction close to the injection mold, and stops when it moves to the set position; then the moving mechanism 2 starts to move, that is, the second horizontal moving cylinder 22 drives the rubber shell clamping mechanism 1 to move in the direction close to the injection mold to the set position. Before reaching the injection mold, the upper mold plate 14 and the lower mold plate 15 are in a separated state, and the first horizontal moving cylinder 116 has driven the positioning block 119 to extend, ready to position the end face of the rubber shell. When the rubber shell clamping mechanism 1 reaches the set position, the positioning block 119 contacts the end face of the rubber shell for positioning; then, the rubber shell The rubber shell body clamping mechanism 1 is actuated, the first cylinder 16 drives the upper template 14 downward, and the second cylinder 17 drives the lower template 15 upward. After the upper and lower templates are in contact, the rubber shell is clamped by the upper positioning groove and the lower positioning groove; then, the moving mechanism 2 drives the rubber shell clamping mechanism 1 to retreat to the set position, and then the unloading mechanism 4 starts to act, the lifting cylinder 41 drives the clamping claw cylinder 43 to rise to the set height, and the clamping claw of the clamping claw cylinder 43 is opened, that is to say, the two support blocks 44 are in an open state, and then the moving mechanism 2 drives the rubber shell clamping mechanism 1 to return, so that one end of the rubber shell is covered with the support block of the clamping claw cylinder 43 and contacts the support block; immediately afterwards, the upper and lower templates are separated, and the moving mechanism 2 drives the rubber shell clamping mechanism 1 to retreat and leave. Since the support block is a movable block and can only support one end of the rubber shell, the rubber shell is overturned into the receiving slide groove under the action of its own weight after the upper and lower templates are withdrawn.

[0039] Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
