[0024] The present invention will be further described in detail below in conjunction with embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0025] The technical solution of the present invention provides an injection molding automatic product taking and sprue separating fixture, which is connected to a manipulator fixture.

[0026] Referring to Figures 1 to 2 , in this embodiment, it includes:

[0027] The fixture main board 1 is connected to the lower end of the manipulator fixture. An opening slot 11 is provided on the fixture main board 1 for the sprue of the product to pass through;

[0028] The punching mechanism is arranged at the lower end of the fixture main board 1 and is used for punching the sprue of the product;

[0029] The positioning mechanism is arranged at the lower end of the fixture main board 1 and is used for positioning and fixing the punching mechanism;

[0030] The fixing mechanism is arranged at the upper end of the fixture main board 1 and is used for gripping and releasing the sprue of the product;

[0031] The gripping mechanism 5 is arranged at the lower end of the fixture main board 1, and the gripping mechanism 5 is arranged adjacent to the positioning mechanism for gripping and releasing the product.

[0032] Optionally, in this embodiment, the automatic product-taking and sprue-separating fixture for injection molding is connected to the manipulator fixture, and includes a fixture main board 1, a punching mechanism, a positioning mechanism, a fixing mechanism, and a clamping mechanism 5. The manipulator fixture clamps the fixture for movement; the fixture main board 1 is connected to the lower end of the manipulator fixture, that is, the manipulator fixture drives the fixture main board 1 to move in a direction close to or away from the product. An opening slot 11 is provided on the fixture main board 1 for the sprue of the product to pass through; the punching mechanism is arranged at the lower end of the fixture main board 1. That is, after the fixture main board 1 approaches the product, the sprue of the product is placed in the opening slot 11, and the punching mechanism completes the operation of punching the sprue of the product; the positioning mechanism is arranged at the lower end of the fixture main board 1. When the fixture main board 1 is located directly above the product, the positioning mechanism is connected and fixed to the product, so that when the punching mechanism punches the sprue, the punching position can be automatically adjusted to ensure the accuracy of the punching point; the fixing mechanism is arranged at the upper end of the fixture main board 1. The sprue of the product passes through the opening slot 11. After the punching mechanism completes the punching of the sprue of the product, the fixing mechanism fixedly clamps the sprue of the product, moves it to the upper end of the collection box under the drive of the manipulator fixture, and the fixing mechanism releases the sprue to complete the punching and automatic collection of the sprue; the clamping mechanism 5 is located at the lower end of the fixture main board 1 and is arranged adjacent to the positioning mechanism. When the positioning mechanism completes the positioning and fixing of the punching mechanism, the clamping mechanism 5 sucks and fixes the product, moves it above the production line under the drive of the manipulator fixture, and then the punching mechanism completes the punching of the sprue of the product. After the punching is completed, the clamping mechanism 5 releases the product onto the production line, and the fixing mechanism clamps the sprue into the collection box; through the setting of the above mechanisms, the automatic clamping of the product and the separation of the sprue are completed, and the sprue is automatically sorted and collected, improving the production efficiency of the product.

[0033] In this embodiment, the punching mechanism includes a fixed bracket 21, a pneumatic cylinder 22, and a pneumatic shear 23. The fixed bracket 21 is arranged at the upper end of the fixture main board 1, the pneumatic cylinder 22 is connected to the fixed bracket 21, and the pneumatic cylinder 22 passes through the opening slot 11, that is, part of the pneumatic cylinder 22 is arranged at the upper end of the fixture main board 1, and part is arranged at the lower end of the fixture main board 1. The pneumatic shear 23 is arranged at the lower end of the fixture main board 1 and is connected to the output end of the pneumatic cylinder 22. Driven by the pneumatic cylinder 22, the pneumatic shear 23 closes to complete the punching of the sprue of the product. In other embodiments, a motor or a screw mechanism can also be used to replace the pneumatic cylinder 22, which is not limited here.

[0034] In this embodiment, the positioning mechanism is configured as multiple positioning posts 3. The multiple positioning posts 3 are all connected to the lower end of the fixture main board 1 by bolts. The positioning posts 3 are used to fixedly connect with the positioning holes on the mold. That is, after the fixture main board 1 moves to the upper end of the mold, the positioning posts 3 press down and connect with the positioning holes on the mold, so that the clamping mechanism 5 can accurately clamp the product. Further, in this embodiment, a buffer pad is provided at the lower end of the positioning post 3. Through the setting of the buffer pad, it is prevented that the positioning post 3 makes hard contact with the mold, resulting in damage to the mold or the positioning post 3. The material of the buffer pad can be selected from materials with buffering performance such as rubber or silica gel.

[0035] In this embodiment, the fixing mechanism includes a driving cylinder 41 and a clamping plate 42. There are two groups of driving cylinders 41, and the two groups of driving cylinders 41 are respectively arranged on both sides of the opening groove 11. The clamping plate 42 is connected to the driving cylinder 41. Under the drive of the two groups of driving cylinders 41, the two groups of clamping plates 42 approach or move away from each other to complete the clamping and releasing of the product nozzle.

[0036] In this embodiment, the clamping mechanism 5 is configured as a vacuum adsorption device. There are multiple groups of vacuum adsorption devices, and the multiple groups of vacuum adsorption devices are all arranged at the lower end of the fixture main board 1. The vacuum adsorption device is used to suck the product. When the vacuum value of the vacuum adsorption device reaches the set value, the manipulator fixture moves the product above the production line to cut the nozzle. After the cutting is completed, the vacuum adsorption device releases the product to the upper end of the production line. In other embodiments, the clamping mechanism 5 can also be configured as a suction cup or a clamping jaw mechanism, which can also realize the clamping and releasing of the product, and will not be limited here.

[0037] In this embodiment, multiple mounting holes 12 penetrating the upper and lower end faces are provided on the fixture main board 1. Through the setting of the multiple mounting holes 12, the manipulator fixture is fixed to the fixture main board 1 by bolts, which is convenient for installation and fixation.

[0038] The above-described embodiments only represent the implementation modes of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
