Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to an automatic cutting device for gate waste. Background Art

[0002] The pouring system of an injection mold usually includes a main runner, a branch runner and multiple gate wastes. The gate waste is connected to the cavity of the injection mold.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0025] Example

[0026] In order to solve the problem of artificial Figure 1 The problem of removing the gate waste B shown in the figure is as follows: Figure 2 As shown, the present application discloses an automatic gate waste removal device, comprising a carrying platform 10, a gate waste clamping and transporting device 20, a gate waste removal mechanism 30 and two carrying jigs 40;

[0027] Two carrying jigs 40 are arranged on the carrying platform 10 in a spaced-apart manner. The two carrying jigs 40 are provided with an escape groove 43 on the opposite sides thereof for allowing the product A to pass through.

[0028] The carrying platform 10 is provided with a through slot 11 between the two carrying fixtures 40;

[0029] The gate waste clamping and handling device 20 includes a rotary lifting drive assembly 21, a bidirectional drive assembly 22, and two clamping members 23. The rotary lifting drive assembly 21 is arranged below the side of the carrier 10 close to the through slot 11. The bidirectional drive assembly 22 is connected to the top of the rotary lifting drive assembly 21. The two clamping members 23 are arranged on the two driving parts of the bidirectional drive assembly 22.

[0030] The gate waste cutting mechanism 30 includes two automatic cutting shears 31 . Preferably, the automatic cutting shears 31 of the present application are pneumatic shears. The two automatic cutting shears 31 are arranged below the through slot 11 near the two supporting jigs 40 .

[0031] During the specific implementation, the operator or the robot places the two products A connected to the gate waste B in the two carrying jigs 40 respectively, and the two horizontal bars of the gate waste B will be respectively located in the two automatic cutting scissors 31. After that, the rotary lifting drive assembly 21 drives the two-way drive assembly 22 to rotate above the vertical bar of the gate waste and drives the two-way drive assembly 22 to descend. When the vertical bar of the gate waste B is located between the two clamps 23, the two-way drive assembly 22 drives the two clamps 23 to move toward each other to clamp it. After the above actions are completed, the two automatic cutting scissors 31 will cut off the two horizontal bars along the product A. Finally, the rotary lifting drive assembly 21 drives the two-way drive assembly 22 to reset, and the two-way drive assembly 22 drives the two clamps 23 to reset. The gate waste B can be unloaded (a waste recycling box can be set at the initial position), and the operator or the robot can take the two products A from the two carrying jigs 40.

[0032] In order to position product A, the supporting fixture 40 of the present application includes a fixture plate 41 and four baffles 42 arranged around the fixture plate 41. The avoidance groove 43 is opened on two baffles 42 facing each other on the two supporting fixtures 40. When product A is placed between the four baffles 42, part of product A will leak out of the avoidance groove 43.

[0033] Preferably, the rotary lifting drive assembly 21 of the present application is a ball spline rotary lifting mechanism. This structure is a known technology. Personnel in this technical field can refer to the Chinese utility model patent with application number 201822165937.0. This application will not go into details here.

[0034] It is also preferred that the bidirectional drive component 22 of the present application is a finger cylinder, and the two clamping parts 23 are fixed on the two fingers of the finger cylinder facing each other. When the finger cylinder of the present application is actuated, the two clamping parts 23 can move toward each other to clamp the vertical rod of the gate waste B. Conversely, when the two clamping parts 23 are reset, the gate waste B can be unloaded.

[0035] Specifically, the clamping member of the present application is a cylindrical block made of rubber material. In this way, the two clamping members 23 can elastically clamp the vertical rod of the gate waste material B, thereby preventing the gate waste material B from slipping during transportation.

Their purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made in accordance with the spirit of the present invention shall be included in the scope of protection of the present invention.
