Problems solved by technology

[0002] The mold is a tool used to make shaped objects. When manufacturing shoe soles, mold assistance is needed. The general shoe sole manufacturing mold is formed by direct injection molding. A pressure plate is directly above the mold to squeeze the material inside the mold. The sole is fine. Some waterproof soles need to be equipped with a plastic bottom film. The plastic bottom film cannot be pressed tightly on the sole by one press, and there are great processing defects.

Embodiment 1

[0038] refer to Figure 1 ~ Figure 4 , In this embodiment, a three-layer shoe sole mold device is proposed, including a bottom film 3, a middle mold 5, an upper mold 8, a hydraulic rod 10, a pressure sensor 16 and a controller.

[0039] The base film 3 can be connected with a connecting frame 2 at the bottom, so as to support the base 1 to a specified height. Through holes, the bolts pass through the holes and are fixedly connected to the base 1, thereby realizing the installation of the bottom membrane 3.

[0040] The bottom film 3 has a mold groove 4 on the upper surface, and the mold groove 4 is used for placing the anti-slip mat and forming a mold.

[0041] One end of the middle mold 5 is rotatably connected to the bottom film 3 , and a transparent mold groove 6 is opened on the middle mold 5 , and the mold groove 6 corresponds to the mold groove 4 .

[0042] One end of the upper mold 8 is rotatably connected to the rotating connection end of the middle mold 5 , and the ...

Embodiment 2

[0048] There is a pipeline on the bottom film 3, one end of the pipeline is connected to the inside of the mold cavity 4, and the other end of the pipeline is connected to the negative pressure gas source. A control valve 13 is arranged on the pipeline, and the control valve 13 is electrically connected to the controller. When the T sensed by the controller is greater than equal to t 1 , the control valve 13 is opened to form a negative pressure inside the mold cavity 4, and the inside of the mold cavity 4 is pumped to make the plastic bottom film adsorb on the non-slip mat, so that all the materials for making the sole are all pressed together, and the plastic bottom film is tightly connected to the non-slip pad. Fit together, not easy to fall off. The negative pressure gas source can be directly connected to the vacuum pump, and can also include a buffer box 11 and an air pump 12. The buffer box 11 can be connected to the pipeline, and the buffer box 11 is connected to the g...

Embodiment 3

[0051] refer to Figure 7 , a kind of three-layer sole processing technology is proposed in the present embodiment, comprises the following steps:

[0052] S1, place the anti-slip mat and the plastic bottom film in the cavity 4 in sequence;

[0053] S2, receiving the bearing weight of the base 1 sensed by the pressure sensor 16;

[0054] S3, judging whether the bearing weight T of the base 1 is equal to t 1 , if yes, execute S4;

[0055] S4, the rotating drive part drives the upper mold 8 and the middle mold 5 to rotate θ 1 ;

[0056] S5, injecting the injection molding liquid into the mold cavity 6, and forming a middle layer structure;

[0057] S6, judging whether the bearing weight T of the base 1 is equal to t 2 , if yes, execute S4;

[0058] S7, the rotating drive part drives the upper mold 8 to rotate θ 2 , the upper mold 8, the middle mold 5 and the bottom film 3 are bonded together to be pressed into the sole.

[0059] The T is equal to t 1 The judgment metho...

Abstract

The invention relates to the technical field of molds, and particularly discloses a three-layer shoe sole mold device and a processing technology, the three-layer shoe sole mold device comprises a bottom film, and a mold groove is formed in the upper surface of the bottom film. And one end of the middle mold is rotationally connected to the bottom mold, through mold grooves are formed in the middle mold, and the mold grooves correspond to one another. One end of the upper die is rotationally connected to the rotary connecting end of the middle die, a pressing block is fixedly connected to the bottom of the upper die, and the shape of the pressing block is matched with and corresponds to that of the die groove. And the elastic connecting structure is connected with the upper die and the middle die, so that the middle die and the upper die elastically rotate within a certain opening angle range. And the rotation driving structure is mounted on the base, is connected with the upper die and is used for driving the upper die to rotate at a fixed angle. And the pressure sensor is used for sensing the bearing weight of the bottom film. And the controller is electrically connected with the pressure sensor and the rotation driving structure. The device is high in automation capacity, convenient and fast to control and accurate in machining.
