The first punch 3 and the second punch 4 are symmetrically arranged. An adjustment component is provided between the first punch 3 and the second punch 4. The adjustment component is used to rotate the first punch 3 and the second punch 4 to adjust their positions. A pushing component is provided on the rear side of the first die 1 and the second die 2. The pushing component is used to adjust the distance between the first die 1 and the second die 2 and the first punch 3 and the second punch 4. The first connecting seat 5 is disposed inside the first die 1 and the second die 2; A die holder 6 is disposed on the surface of the first connecting seat 5, and a filling cavity 61 is provided inside the die holder 6; The punch base 8 has a material storage cavity inside that matches the filling cavity 61. The die base 6 has a locking groove on its surface, and the punch base 8 has a locking protrusion on its surface that matches the locking groove.

[0018] This embodiment provides a horizontal two-color injection mold, which includes a first concave mold 1, a second concave mold 2, a first punch 3, a second punch 4, and an adjusting assembly. During operation, the first concave mold 1 and the first punch 3 are closed. A first injection device outside the mold injects a first raw material into the closed mold. The raw material cools and solidifies within the mold. After solidification, the first concave mold 1 and the first punch 3 separate, and the formed first part of the product remains attached to the first punch 3. The adjusting assembly rotates the first punch 3 and the second punch 4 to adjust their direction. The first part of the product rotates with the first punch 3 to the position of the second concave mold 2, where the first punch 3 and the second concave mold 2 close. The second injection device then injects a second raw material into the first punch 3 and the second concave mold 4 containing the first part of the product. Between two injection molding processes, two raw materials combine in the mold to form a complete two-color or two-material product. After the second raw material solidifies, the injection molding machine opens the mold, and the complete two-color or two-material product is removed from the mold. The entire device can complete the injection molding of two colors or materials on the same injection molding machine, reducing the time spent changing molds and equipment, improving production efficiency, and eliminating the need for multiple injection molding or additional assembly steps. The horizontal two-color injection molding process can reduce production costs and scrap rates, and can create products with complex patterns and color combinations, enhancing the visual appeal of the product. It can also achieve multiple functions in a single product depending on the different raw materials injected in the two injections, such as high temperature resistance, wear resistance, or impact resistance, and can handle the processing and production of larger products.

[0019] In a further embodiment of this invention, a pushing component is provided on the rear side of both the first die 1 and the second die 2. The pushing component is used to adjust the distance between the first die 1 and the second die 2 and the first punch 3 and the second punch 4.

[0020] In this embodiment, the pushing components on the rear side of the first die 1 and the second die 2 can respectively attach them to the first punch 3 and the second punch 4, or pull them out of the first punch 3 and the second punch 4, providing space for them to rotate and adjust their direction.

[0021] In a further embodiment of this invention, the pushing component includes an electric lead screw and a support plate, with the electric lead screw evenly disposed on the outer sides of the first die 1 and the second die 2.

[0022] In this embodiment, the electric lead screw adjusts the lateral position of the first die 1 and the second die 2 to make adjustments.

[0023] In a further embodiment of this invention, the adjustment component includes a positioning plate and a drive motor. The first punch 3 and the second punch 4 are respectively disposed on the two side surfaces of the positioning plate. The top of the positioning plate is provided with a drive motor, which is used to drive the positioning plate to rotate.

[0024] In this embodiment, the adjustment component drives the first punch 3 and the second punch 4 to rotate and adjust the direction, so that the first part of the product is rotated together with the first punch 3 to the position of the second die 2, and then the first punch 3 and the second die 2 close.

[0025] In a further embodiment of this invention, a first connecting seat 5 is fixedly provided between the first die 1 and the second die 2 and the die base 6. A die fixing block 51 is provided around the surface of the first connecting seat 5, and a die connecting groove 52 is uniformly provided inside the first connecting seat 5.

[0026] In this embodiment, the first connecting seat 5 positions and installs the die holder 6 with the first die 1 and the second die 2.

[0027] In a further embodiment of this invention, a fixing plate 611 is uniformly provided at the top and bottom of the filling cavity 61, a guide plate 62 is uniformly provided on the surface of the die holder 6, a locking block 63 is fixedly provided on the outside of the guide plate 62, an exhaust pipe 64 is connected to the top and bottom of the die holder 6 and extends into the filling cavity 61, an installation cavity 65 is uniformly provided on the surface of the die holder 6, and the guide plate 62 is locked inside the installation cavity 65.

[0028] In this embodiment, the cavity mold base 6 adopts a four-sided symmetrical side-locking structure to avoid flash caused by offset during mold closing. The spacing of the injection molding machine nozzles must be consistent with the spacing of the gate in the filling cavity 61. If there is a difference, the ejector pin hole must be designed as a waist-shaped structure to compensate for the offset. The punch mold base 8 is equipped with an ejection system. The two ejection systems are completely separated, and the ejector pin layout is rotationally symmetrical to avoid interference. All water inlets and outlets are limited to the top and bottom sides of the cavity mold base 6 to avoid hose entanglement. In a further embodiment of this invention, a second connecting seat 7 is fixedly provided between the first punch 3 and the second punch 4 and the punch base 8.

[0029] In this embodiment, after the punch holder 8 rotates and adjusts its direction with the first punch 3 and the second punch 4, it matches and engages with the die holder 6 in the first die 1 and the second die 2 respectively, thus completing the overall processing procedure.

[0030] In a further embodiment of this invention, guide posts 9 are uniformly arranged inside the die holder 6.
