Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] The preferred embodiment of this utility model is an S-shaped flow channel double-groove injection mold, such as... Figures 1-4 As shown, the mold includes an upper mold core 10 and a lower mold core 20 that fit together. Two first sliding grooves 30 are arranged side-by-side on the upper surface of the lower mold core 20. The front and rear ends of the first sliding grooves 30 penetrate the side walls of the lower mold core 20, respectively. Two sliding block mold cores 40 slide side-by-side within the first sliding grooves 30 in the front-rear direction. Injection grooves 50 are longitudinally provided on the opposite side walls of the two sliding block mold cores 40. The two injection grooves 50 enclose and form a vertically penetrating injection cavity 300. Each first... Each of the two injection cavities 300 in the slide groove 30 is provided; the bottom surface of the first slide groove 30 is provided with an inner cavity forming cam 60 coaxial with the injection cavity 300, the lower end of which passes through the lower mold core for easy replacement and disassembly; the bottom surface of the upper mold core 10 is provided with a glue inlet channel 70, the two ends of which are located above the two first slide grooves 30 respectively, and the two injection cavities 300 in the first slide groove 30 are connected to the glue inlet channel 70.

[0027] During injection molding, the injection molded part is laterally moved away by two sliding mold cores 40 that can open and close. At this time, non-destructive material removal can be achieved. The workpiece can be easily removed without applying excessive pushing or pulling force to the injection molded part. Compared with the traditional mold opening and material removal method, the material removal method of this solution is easier and can avoid axial pulling force between the product and the inner wall of the injection cavity 300, effectively ensuring the material integrity of the product and thus ensuring the demolding yield.

[0028] In this embodiment, the two injection cavities 300 in the first groove 30 and the inlet 400 of the inlet runner 70 are arranged in the left-right direction. The inlet runner 70 is S-shaped and its two ends are located on the front and rear sides of the injection cavity 300, so that when the two diagonally opposite slider mold cores 40 move away from each other and the mold opens, the gate in the inlet runner 70 can be demolded simultaneously, reducing the adhesion area between the gate and the slider mold core 40 and facilitating material removal.

[0029] In this embodiment, a T-shaped runner groove 80 is provided on the side wall of the slider mold core 40 located between the two injection grooves 50. The two ends of the lateral end of the T-shaped runner groove 80 are respectively connected to the injection grooves 50 on the left and right sides. The longitudinal end of the T-shaped runner groove 80 extends upward through the upper surface of the slider mold core 40. The two T-shaped runner grooves 80 facing each other at the front and rear together form a connecting runner. The two ends of the injection runner groove 70 are respectively connected to the upper ends of the two connecting runners. The T-shaped runner groove 80 can reduce the height of the molten glue entering the bottom surface of the injection groove 50, avoiding bubbles and flow marks.

[0030] The mold described in this embodiment also includes an upper mold base 90 and a lower mold base 100 that fix the upper mold core 10 and the lower mold core 20 respectively. The upper mold core 10 is embedded on the lower surface of the upper mold base 90, and the injection port 500, which communicates with the sprue 400 of the upper mold core 10, is provided on the upper mold base 90 and penetrates its top surface. Of course, in order to further speed up the demolding speed, the lower mold base 100 is also provided with ejector pins 110 for moving up and down to eject the injection molded part and the sprue.

[0031] The mold described in this embodiment also includes a push module 120 that pushes two opposing sliding mold cores 40 to close or open, thereby realizing the operation process of mold closing injection and mold opening material removal. Specifically, the push module 120 includes two movable seats 121 respectively disposed on the front and rear sides of the first slide groove 30, and two guide pillars 122 that push the two movable seats 121 to separate or close. The sliding mold core 40 is connected to the movable seats 121. The lower mold base 100 is provided with a second slide groove 130 for the movable seats 121 to slide back and forth. The two guide pillars 122 are both longitudinally inclined on the upper mold base 90. The two guide pillars 122 are arranged in a figure-eight shape. The movable seats 121 are provided with guide inclined holes 140 that are adapted to the guide pillars 122. Through the inclined guide pillars 122 and guide inclined holes 140, the upper mold core 10 can simultaneously open the sliding mold core 40 to the outside during the opening process, thereby realizing the automatic separation of the injection molded part from the inner wall of the injection cavity 300.

[0032] In this embodiment, the push module 120 also includes a fixing seat 123 located at the bottom of the upper mold base 90. There are two fixing seats 123. When assembled, the two fixing seats 123 press against the two slider mold cores 40 to ensure the tightness of the gap between the injection molding grooves 50 and avoid the appearance of defective sprues.

[0033] In this embodiment, a positioning groove 150 is provided on the bottom surface of the second slide groove 130 corresponding to the fixed seat 123, and a positioning protrusion 1231 is provided at the lower end of the fixed seat 123 corresponding to the positioning groove 150. When assembled in place, the inner wall of the end of the positioning groove 150 away from the first slide groove fits and abuts against the outer wall of the positioning protrusion 1231 to reduce the elastic deformation of the lower end of the fixed seat 123 facing outward and ensure the stability of the clamping force on the two slider mold cores 40.

[0034] In this embodiment, a first inclined surface 1232 is provided on the side wall of the fixed seat 123 near the movable seat 121, and a second inclined surface 1211 is provided on the movable seat 121 corresponding to the first inclined surface 1232. The two first inclined surfaces 1232 are arranged in a figure-eight shape. When assembled, the first inclined surface 1232 abuts against the second inclined surface 1211 to push the slider mold core 40 toward the horizontal center position.

[0035] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
