Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 to 4, a two-color injection mold comprises a first mold body 1 for injecting hard glue and a second mold body 2 for injecting soft glue,

the first die body 1 comprises a first fixed die component 11 and a first movable die component 12, four first sliding blocks 13 capable of moving in opposite directions are arranged on the first movable die component 12 at the same time, the first fixed die component 11, the first movable die component 12 and the four sliding blocks jointly form a first die cavity, inclined grooves 3 for inclined pins 33 to penetrate through are formed in the four first sliding blocks 13, two telescopic first elastic terminals 31 are arranged on two sides of the inner wall of each inclined groove 3, and a first injection port 14 communicated with the first die cavity is formed in the first fixed die component 11;

the second die body 2 comprises a second fixed die component 21 and a second movable die component 22, four second sliding blocks 23 which can move in opposite directions simultaneously are arranged on the second movable die component 22, the second fixed die component 21, the second movable die component 22 and the four sliding blocks jointly form a second die cavity, inclined grooves 3 for inclined pins 33 to pass are formed in the four second sliding blocks 23, two telescopic second elastic terminals are arranged on two sides of the inner wall of each inclined groove 3 respectively, a second injection port 24 communicated with the first die cavity is formed in the second fixed die component 21, and the second die body further comprises inclined pins 33 arranged on the second fixed die component 21

When the structure works, firstly, hard plastic mold injection molding is carried out in the first die body 1, after the hard plastic mold injection molding is carried out, the first movable die and the second movable die component 22 are rotated and exchanged under the driving of an external injection molding machine, the inclined pin 33 on the second movable die component 22 overcomes the elastic force of the first elastic terminal 31 and enters the inclined groove 3, meanwhile, the slide block does not move, after die assembly, soft plastic injection molding is carried out, after the injection molding is finished, the first fixed die component 11 and the second movable die component 22 are opened, when the inclined pin 33 on the first fixed die component 11 moves relative to the slide block, the first elastic terminal 31 does not move, so that the inclined pin 33 pushes the first elastic terminal 31 to drive the slide block to outwards withdraw, and the demoulding operation is realized, the structure does not design the inclined pin 33 on the first fixed die component 11, designs the inclined pin 33 on the second fixed die component 21 and simultaneously cooperates with the use of the elastic terminal, so that the slide block does not move when the mold is changed, thereby solving the problem that the product is crushed when the sliding block is withdrawn and enters again.

On the basis, when the taper pin 33 is located in the chute 3, the taper pin 33 is the plane towards the first elastic terminal 31 one side, the first elastic terminal 31 or the second elastic terminal include the elastic end body, be provided with first spring between elastic end body and the slider, planar setting can conveniently drive the elastic end body and drive the slider outwards to withdraw from to it is more stable when making the slider move.
