Description

Technical Field

[0001] The utility model relates to the technical field of sole preparation tools, in particular to an injection moulding tool for soles used in automatic processing. Background Art

[0002] Traditional sole production usually adopts the injection moulding method to form in one step. After injecting the injection liquid into the bottom film groove, the shoe body is sleeved on the shoe last, and the shoe last is fixed on an external driving device. The driving device drives the shoe body to move downward so that the insole of the shoe body enters the bottom film groove. Then, the shoe body is fixed by a shoe body limiting tool, and the injection liquid is formed into a sole through post-treatment heat treatment and connected to the bottom of the shoe body. However, during the sole injection moulding process, the shoe body is prone to shaking under the influence of external stress, resulting in the connection accuracy between the shoe body and the injection-moulded sole being affected, and even the problem of the connection failure between the shoe body and the sole. Moreover, the traditional shoe body limiting tool requires manual control by an operator, which greatly affects the clamping strength of the shoe body and the stability of the shoe body, thereby affecting the connection accuracy between the sole and the shoe body. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides an injection moulding tool for soles used in automatic processing to solve the problems that the shoe body is prone to shaking during the sole injection process in the prior art and the traditional sole injection clamping tool cannot be automatically opened or closed.

A bottom film groove for injecting external injection liquid is arranged on the base. The driving seat is composed of a left clamping arm and a right clamping arm. The end of the left clamping arm is hinged to the end of the right clamping arm, and the left clamping arm and the right clamping arm are arranged to swing relatively. Notches are recessed on the inner wall surfaces of the left clamping arm and the right clamping arm. The two notches and the bottom film groove form an injection groove for the external shoe body to be processed to contact the injection liquid. A driving member is arranged between the left clamping arm and the right clamping arm to drive the right clamping arm to swing relative to the left clamping arm so that the inner wall surfaces of the left clamping arm and the right clamping arm are closely attached and the two notches are combined with the bottom film groove.

[0005] The advantages of adopting the above technical solutions are as follows: in the above technology, when the left clamping arm and the right clamping arm are closed, the two notches clamp and limit the shoe body to be processed, avoiding excessive shaking of the shoe body and affecting the connection accuracy between the sole and the shoe body. At the same time, the driving member drives the right clamping arm to swing relative to the left clamping arm to realize the automatic closing and automatic opening of the left clamping arm and the right clamping arm, thereby improving the connection strength between the two and realizing automatic driving, so as to realize the automatic clamping of the shoe body to be processed and the automatic separation after sole injection, so as to remove the processed shoe body from the bottom film groove. The whole process is automated, thereby improving the injection efficiency and injection accuracy.

[0006] The present utility model is further provided with: a slide rail is arranged on the left clamping arm, the radial cross-section of the slide rail is arc-shaped and the arc direction of the slide rail is arranged to be consistent with the swinging direction of the right clamping arm, a toothed groove is arranged on the slide rail along its arc direction, a through groove for the slide rail to pass through is arranged on the right clamping arm, the shape of the through groove is adapted to the shape of the slide rail, an operation cavity is arranged on the right clamping arm, the driving member includes a small motor arranged in the operation cavity, a gear is arranged on the output end of the small motor, a slot is communicated between the operation cavity and the through groove, and a part of the gear passes through the slot and is meshed with the toothed groove.

[0007] The advantages of adopting the above technical solution are as follows: when the left clamping arm and the right clamping arm need to be automatically closed or automatically opened, the small motor is automatically started according to the control of an external industrial control computer. The small motor starts and its output shaft rotates forward or backward, thereby driving the gear to rotate synchronously. Since the gear is meshed with the toothed groove, the gear can drive the right clamping arm to move along the arc direction of the slide rail when rotating, so as to realize the automatic closing or automatic opening of the left clamping arm and the right clamping arm. Through the setting of the above technology, the automatic operation of the left clamping arm and the right clamping arm is realized, so as to realize the automatic clamping of the shoe body to be processed and the automatic separation after the sole is injection-molded, so as to take out the processed shoe body from the bottom film groove. The whole process is automated, thereby improving the injection-molding efficiency and injection-molding accuracy.

[0008] The present utility model is further provided with: the small motor is arranged close to the starting end position of the right clamping arm.

[0009] The advantages of adopting the above technical solution are as follows: in the above technology, the small motor is arranged close to the starting end position of the right clamping arm, so that when the small motor drives the gear to reach the maximum cooperation state with the toothed groove, the starting end of the right clamping arm can be stably attached to the starting end of the left clamping arm, thereby improving the connection strength between the two.
