[0009] Furthermore, the sliding bar is slidably connected to the transverse guide rod.

[0010] In this embodiment, the fixing strip is fixedly connected to the transverse guide rod.

[0011] In this embodiment, an abutment block is fixedly connected to the center of one side of the half mold close to the sliding bar.

[0012] In this embodiment, a wedge-shaped abutting piece is fixedly connected to the front of one side of the half mold close to the sliding bar.

As the half mold gradually separates from the molded part, the wedge-shaped abutment sheet will contact the pressure push sheet before the abutment block, pushing the wedge-shaped blocking block to move backward, so that the sliding bar loses its obstruction, and then the abutment block and the sliding bar move, which can push the sliding bar to move, so as to realize the separation between the top plate and the molded part.

[0021] During the injection molding process, the electric push rod is controlled to be in a contracted state so that the active gear contacts with the driven gear 2. At this time, starting the motor will drive the double-headed cam to rotate, so that the limit block can be moved back and forth along the limit groove by toggling the push plate, and then the half mold can be driven to move back and forth repeatedly, which has a shaking effect, so that the injection molding material can be injected more fully after entering the half mold. After the material is cooled and formed, the electric push rod is controlled to extend so that the active gear and the driven gear 1 are meshed and transmitted, and the rotating rod is controlled to rotate, so as to achieve the demolding and splitting effect of the half mold, the top plate and the molded part.

[0029] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Example: Figure 1 and Figure 3 As shown, a multi-station multi-color silicone integrated molding mold is provided, comprising a U-shaped base 1, two transverse guide rods 2 are arranged on the inner upper side of the U-shaped base 1, and the outer side walls of the two transverse guide rods 2 are slidably connected with a half mold 3, and the opposite sides of two adjacent half molds 3 are fitted together;

[0031] The two half molds 3 that are relatively fitted to each other on the left and right form a molding mold, which is convenient for multi-color silicone injection molding. At the same time, by setting a multi-group molding mold composed of multiple groups of half molds 3, it is convenient to simultaneously mold multiple groups of workpieces. At the same time, the half mold 3 can slide along the transverse guide rod 2, which is convenient for taking out the injection molded workpiece by splitting the two half molds 3;

[0032] A rotating rod 4 is rotatably connected to the lower part of the U-shaped base 1 through a rotating shaft, and a plurality of bidirectional screw tubes 5 are fixedly connected to the outer wall of the rotating rod 4. Two concave moving parts 6 are threadedly connected to the outer wall of the bidirectional screw tube 5.

The front end and the rear end of the guide longitudinal rod 8 are fixedly connected to a fixed block 9. The top end of the fixed block 9 is fixedly connected to the bottom of the half mold 3.

[0033] By rotating the rotating rod 4, the bidirectional screw tube 5 can be driven to rotate together, so that the two concave moving parts 6 outside the bidirectional screw tube 5 move away from each other, and then the two half molds 3 can be pulled away from each other through the traction block 7 and the fixed block 9 to achieve the splitting effect, so that after injection molding, it is convenient to split the molded part and the mold.

[0034] like Figure 4 , Figure 5 and Figure 6 As shown, an ejection groove 10 is provided on the inner side of the half mold 3, and a top plate 11 is engaged with the inner side of the ejection groove 10, and the opposite sides of two adjacent top plates 11 are fixedly connected with ejector rods 12, and the ends of the multiple ejector rods 12 away from the top plates 11 respectively penetrate the outer sides of the multiple half molds 3, and are respectively slidably connected with the multiple half molds 3, and the opposite ends of the two adjacent ejector rods 12 are located on the outer sides of the two transverse guide rods 2 and are fixedly connected with sliding bars 14, and the sliding bar 14 is away from the side of the half mold 3 and is located on the outer sides of the two transverse guide rods 2. A fixing bar 15 is provided, and a plurality of springs 16 are fixedly connected between the adjacent fixing bars 15 and the sliding bars 14;

[0035] The sliding bar 14 is slidably connected to the transverse guide rod 2;

[0036] The fixing strip 15 is fixedly connected to the transverse guide rod 2;

[0037] An abutment block 17 is fixedly connected to the center of one side of the half mold 3 close to the sliding bar 14;

[0038] When the rotating rod 4 rotates to control the separation of the two half molds 3, under the pressure of the spring 16 and due to the adhesion effect of the injection molded part itself, it will fit closely with the two top plates 11. At this time, as the rotating rod 4 moves, it will first separate from the half mold 3. As the half mold 3 moves, the abutment block 17 will contact the sliding bar 14 and squeeze and push the sliding bar 14 to move toward the fixed bar 15, so that the top plate 11 is separated from the molded part, thereby completing the separation and separation of the molded part and the mold through a two-step separation effect;

[0039] A wedge-shaped abutment piece 18 is fixedly connected to the front of one side of the half mold 3 close to the sliding bar 14;

[0040] The lower surface of the fixed bar 15 is fixedly connected to two fixed blocks 2 19, and the opposite sides of the two fixed blocks 2 19 are fixedly connected to a sliding bar 20. The outer wall of the sliding bar 20 is slidably connected to a blocking piece 21, and the side of the blocking piece 21 close to the sliding bar 14 is fixedly connected to a wedge-shaped blocking block 22, and the wedge-shaped blocking block 22 is in contact with the opposite side of the sliding bar 14. The front surface of the blocking piece 21 is fixedly connected to a pressure push piece 23, and the pressure push piece 23 and the wedge-shaped abutting piece 18 are on the same horizontal plane. The outer wall of the sliding bar 20 is sleeved with a spring 24;

[0041] The rotating rod 4 rotates to control the separation of the two half molds 3. Before the abutment block 17 contacts the half mold 3, the wedge-shaped blocking block 22 blocks the limiting sliding bar 14, so that when the half molds 3 are separated, the two top plates 11 can stably clamp the molded part, which is convenient for the separation of the half mold 3 and the molded part. As the half mold 3 gradually separates from the molded part, the wedge-shaped abutment sheet 18 contacts the pressure push sheet 23 before the abutment block 17, pushing the wedge-shaped blocking block 22 to move backward, so that the sliding bar 14 loses its obstruction, and then the abutment block 17 and the sliding bar 14 move, which can push the sliding bar 14 to move, so as to realize the separation between the top plate 11 and the molded part.

[0042] like Figure 2 As shown, both sides of the U-shaped base 1 are provided with a limit groove 25, the limit rod 26 is slidably connected inside the limit groove 25, and two limit blocks 27 are slidably connected to the outer wall of the limit rod 26, and a spring 3 28 is fixedly connected between the limit block 27 and the limit groove 25, and the limit block 27 is fixedly connected to the opposite end of the transverse guide rod 2, and a connecting plate 29 is fixedly connected to the rear surface of the limit block 27 located at the inner front of the limit groove 25 and at the right end of the rotating rod 4, and a push plate 30 is fixedly connected to the right side of the connecting plate 29;

[0044] The right end of the rotating rod 4 is fixedly connected to a driven gear 1 35 located on the right side of the U-shaped base 1. The driven gear 1 35 is meshed and connected with the driving gear 34. The right side of the U-shaped base 1 is located above the driving gear 34 and is rotatably connected to a driven gear 2 36 through a rotating shaft. A double-headed cam 37 is fixedly connected to the right center of the driven gear 2 36 and located behind the pushed piece 30.

[0045] During the injection molding process, the electric push rod 31 is controlled to be in a contracted state, so that the active gear 34 contacts the driven gear 36. At this time, starting the motor 33 will drive the double-headed cam 37 to rotate, so that the limit block 27 can be moved back and forth along the limit groove 25 by toggling the push plate 30, and then the half mold 3 can be driven to move back and forth repeatedly, which has a shaking effect, so that the injection molding material can be injected more fully after entering the half mold 3.
