Detailed Description

The present invention is further described in detail below with reference to examples so that those skilled in the art can implement the invention with reference to the description.

It will be understood that terms such as "having," "including," and "comprising," when used herein, do not preclude the presence or addition of one or more other elements or groups thereof.

As shown in fig. 1-3, a stripping end on an injection mold stripping mechanical arm is used for installing at the end of the mechanical arm to strip a perforated injection molding part, the stripping end comprises a base 1 and a vacuum chuck 2, the vacuum chuck is arranged on the base, a plurality of groups of arc pipes with openings on the upper end surface of the base are arranged in the base, each group of arc pipes comprises 4 arc pipes 3 which are arranged in an annular mode, arc claws 4 which are adapted to the shapes of the arc pipes are arranged in the arc pipes, the arc claws are connected with the arc pipes in a sealing mode, and the arc claws can slide along the arc pipes and extend out of the arc pipes so as to clamp the injection molding part B from a hole B1. The arc-shaped pipe can be coated with lubricant to achieve better sealing and lubricating effects.

The bottom of the arc-shaped pipe is communicated with a high-pressure air pipe 5, the arc-shaped claws are pushed by the high-pressure air pipe to extend out of the base, and the arc-shaped claws in each group of arc-shaped pipes which are arranged in an annular mode are scattered around after extending out. The position of arc claw should be corresponding with the hole position of injection molding to make the arc claw stretch out the back and pass from the downthehole of injection molding, the arc claw opens the back and props up the hole of injection molding or clinch the injection molding from the injection molding another side, stretches out through pneumatic control arc claw, simple structure, and with low costs, and it is convenient to maintain.

The arc-shaped pipe is arranged in a plane vertical to the upper end face of the base.

And a resetting device 6 is arranged at the bottom of the arc-shaped claw.

The resetting device is a spring, one end of the spring is connected with the bottom of the arc-shaped claw, and the other end of the spring is connected with the inner wall of the arc-shaped pipe.

The arc-shaped claw is made of hard elastic materials. Adopt elastic material can prevent that the arc claw from causing hard damage to the injection molding, and make the life and the adaptability of arc claw strengthened.

And the top of the arc claw is provided with a wear-resistant rubber bulge 7. The protruding difficult injury that causes the injection molding surface of wear-resisting rubber, and multiplicable arc claw improves the stability of snatching to the frictional force of injection molding.

The number of the vacuum suction cups is not more than three. Generally, one vacuum chuck can realize stripping, and for a stripping piece with a hole at the center, 1 to 3 scattered vacuum chucks can be used for stripping.

The arc-shaped pipe orifice part is provided with a detachable plug 8.

The plug is in threaded connection with the arc-shaped pipe orifice. According to the open position difference of different injection moldings, arranging of arc pipe can have the multiunit, remove the stopper of corresponding arc pipe, the arc pipe that other stoppers do not remove then no longer stretches out the curved claw, for example, the injection molding is the disc of a middle trompil, vacuum chuck locates the base middle part, remove a set of with the stopper apart from the suitable (the arc pipe is aimed at the hole, vacuum chuck can adsorb with other positions of injection molding) 4 arc pipe's stopper, when the arc claw stretches out, can follow injection molding trompil department and clamp the disc.

As shown in fig. 3, during material stripping, the mechanical arm moves a group of opened arc-shaped pipes to a position corresponding to an opening B1 of an injection molding part B, the injection molding part is firstly stripped from a mold by using a vacuum chuck, and simultaneously, the arc-shaped claws are extended by ventilating a high-pressure air pipe, the arc-shaped claws penetrate through the openings of the injection molding part to support holes of the injection molding part or clamp the injection molding part from the other side of the injection molding part, so that the injection molding part can be stably moved even if the suction force of the vacuum chuck is lost.

While the embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments, which are fully applicable in all kinds of fields suitable for the invention, and further modifications may be readily made by those skilled in the art, and the invention is therefore not limited to the specific details and embodiments shown and described herein, without departing from the general concept defined by the claims and their equivalents.
