Detailed Description

Referring to fig. 1 to 3, the accessory positioning and feeding jig of the two-shot injection molding product provided by the embodiment is used for positioning accessories of an interphone shell, and the accessories comprise a light guide strip 5 and a plurality of keys 4.

The accessory positioning and feeding jig for the bijection injection molding product comprises a base 1, a first positioning seat 2 and a second positioning seat 3, wherein the first positioning seat 2 is fixedly arranged in the middle of the base 1, the length direction of the first positioning seat 2 is perpendicular to that of the base 1, the second positioning seat 3 can be slidably arranged on the base 1 and located on one side of the first positioning seat 2, the length direction of the second positioning seat 3 is parallel to that of the first positioning seat 2, and the sliding direction of the second positioning seat 3 is perpendicular to the top surface of the base 1. For convenience of explanation, the longitudinal direction of the base 1 is defined as the X direction, the width direction of the base 1 is defined as the Y direction, and the sliding direction of the second positioning stand 3 is defined as the Z direction.

Two positioning holes 21 and a plurality of positioning grooves 22 are formed in the first positioning seat 2, and the two positioning holes 21 are arranged at two ends of the first positioning seat 2 along the Y direction and are used for being matched with positioning columns of the material taking manipulator. The positioning slots 22 are located between the two positioning holes 21, and the plurality of positioning slots 22 are arranged in a crisscross manner, that is, the plurality of positioning slots 22 are correspondingly arranged according to the designed position on the casing of the interphone. The shape of the positioning groove 22 is matched with the shape of the corresponding key 4, so that in order to facilitate the worker to distinguish the installation position and the direction of each key 4, a mark and an arrow mark can be marked on one side of each positioning groove 22, and the mark and the corresponding key 4 are arranged in a one-to-one correspondence manner.

The second positioning seat 3 is provided with a groove 31, a material pushing block 35, a lifting driving device 36, four mounting grooves 32 and four air vent channels 33. Two liang are a set of for four mounting grooves 32, and two mounting grooves 32 with the internal are arranged along Y to corresponding, and two sets of mounting grooves 32 are arranged along X to parallel, and mounting groove 32 is used for fixing a position leaded light strip 5, and the both ends cartridge of leaded light strip 5 is in two mounting grooves 32 of same group. The groove 31 is arranged in the middle of the second positioning seat 3 in an extending manner along the X direction, the mounting grooves 32 are located on two sides of the groove 31, and the groove 31 is respectively communicated with the mounting grooves 32 on two sides. In the Z direction, the bottom of the groove 31 is lower than the bottom of the mounting groove 32. The material pushing block 35 is slidably disposed in the groove 31, the lifting driving device 36 is fixedly connected to the bottom wall of the second positioning seat 3, the lifting driving device 36 drives the material pushing block 35 to move back and forth in the groove 31 along the Z direction, that is, the lifting driving device 36 drives the material pushing block 35 to move back and forth along the groove depth direction of the mounting groove 32, so as to push the light guiding strip 5 upwards out of the mounting groove 32 from the middle of the light guiding strip 5. Two air passages 33 are respectively arranged at two sides of the groove 31, and each air passage 33 is respectively communicated with the two mounting grooves 32 on the same side. Specifically, a first end of the ventilation channel 33 is provided with a connection port, the connection port is located on the side wall of the second positioning seat 3, a second end of the ventilation channel 33 is provided with two openings, and the two openings are located at the bottoms of the two mounting grooves 32 respectively. The first end of the ventilation channel 33 is communicated with the air supply device through an air pipe and is used for blowing air into the installation groove 32, so that the end part of the light guide strip 5 inserted into the installation groove 32 has upward acting force to assist in pushing up the light guide strip 5. Because the lifting driving device 36 is fixedly connected to the bottom wall of the second positioning seat 3, in order to prevent the lifting driving device 36 from colliding with the base 1, the avoiding groove 12 is formed in the middle of the base 1, and the lifting driving device 36 is arranged opposite to the avoiding groove 12.

Two ends of the second positioning seat 3 are respectively provided with a linear bearing 34, that is, two linear bearings 34 are arranged in a row along the Y direction, and the linear bearings 34 extend along the Z direction.
