An injection mold that is convenient for side molding, please refer to Figure 1-4, includes an upper mold and a lower mold that can be opened and closed. The mold includes a lower mold base 400, a lower template 500, and a lower mold core 600 from bottom to top. When the upper mold and the lower mold are closed, a molding cavity is formed between the upper mold core 300 and the lower mold core 600. In this implementation The injection mold is used to produce toy shells. In other embodiments, the structure of the upper mold core 300 and the lower mold core 600 can be designed according to the structure of the produced product to form different products, and the melted plastic is injected into the molding cavity After molding, the upper mold moves upwards to separate from the lower mold, and then the product is demoulded and taken out. This is a prior art, and will not be described in detail; A stepped structure is formed on both sides, and a first limiting block 220 is fixed on the upper template 200 on both sides of the first side pusher 210, and the first limiting block 220 and the stepped structures on both sides of the first side pusher 210 are mutually locked. position, so that the first side pusher 210 is restricted from moving up and down, and can only move horizontally left and right; a first drive column 110 is fixed at the position corresponding to the first side pusher 210 on the left side of the upper die base 100, and the bottom of the first drive column Part 110 is embedded in the first column hole 211 formed on the first side pusher 210. When the first drive column 110 moves with the upper mold base 100, it drives the first side pusher 210 to move left and right, and the first side pusher 210 moves right and left. The side is provided with a first convex portion 212 extending toward the molding cavity; the first convex portion 212 protrudes toward the molding cavity for molding the left side of the product; the front center of the lower template 500 is provided with a second side pusher 510, Both sides of the two side pushers 510 are provided with a second stopper 520 connected to the lower template 500 to limit the up and down movement of the second side pusher 510. The second stopper 520 is the same as the first stopper 220. The two side pushers 510 can only move forward and backward under the limit of the second limit block 520. The front side of the upper template 200 is provided with a second drive column 230 corresponding to the second side pusher 510, and the bottom of the second drive column 230 is embedded in the second The second column hole 511 formed on the two side pushers 510, the second side pusher 510 rear side is provided with the second convex part 512 extending to the molding cavity, the second convex part 512 stretches to the molding cavity, to the front of the product Side molding, the utility model realizes simultaneous molding of two sides of the product through the horizontally movable first side pusher 210 and the second side pusher 510, the molding effect is better, and the demoulding is not affected, omitting the product Secondary molding processing improves production efficiency.

Furthermore, the top of the first driving column 110 is connected to the upper mold base 100, and the left side of the middle section is provided with an inclined surface, which makes the middle section of the first driving column 110 form a structure that is wide at the top and narrow at the bottom. A slot hole 240 matching the structure of the middle section of the driving column 110, the slot hole 240 cooperates with the middle section of the first driving column 110 to ensure that the upper mold plate 200 can drive the first driving column 110 to move when the upper mold base 100 moves upward, and the first driving column When the 110 is pressed down, it also squeezes the upper template 200 to fit the lower template 500; the bottom of the first driving column 110 is provided with an outwardly inclined inclined portion 111, and the first column hole 211 matches the structure of the inclined portion 111. The side surface of a column hole 211 and the inclined portion 111 are both inclined surfaces. Through the cooperation between the first column hole 211 and the inclined portion 111, the first driving column 110 drives the first side pusher 210 to move outward when moving upward, and vice versa. Move, that is to say, when the upper mold and the lower mold are closed, the first side pusher 210 wants to move inside, so that the first convex part 212 protrudes from the molding cavity. When the plastic cools, even if the left side of the product forms the first convex The structure of the part 212, by changing the structure of the first convex part 212, different structures can be formed on the left side of the product. After the product is formed, the upper mold and the lower mold are separated, the first driving column 110 moves upward, and the first side pushes The piece 210 is far away from the molding cavity and does not affect the demoulding of the product.

Furthermore, the top of the second side pusher 510 is provided with an upper convex portion 511 protruding from the upper surface of the lower template 500. The front side of the upper convex portion 511 is an inclined plane, specifically inclined from the upper rear to the lower front. The upper template 200 The position corresponding to the upper convex part 511 is provided with the first convex part groove 250 corresponding to the structure of the upper convex part 513; the second driving column 230 is a structure inclined outward from top to bottom, and the top is fixed on the upper template 200 by clamping position. The top surface of the second driving column 230 is flush with the upper surface of the upper template 200, so that when the upper template 200 moves upward, it will drive the second driving column 230 to move upward, and when the upper mold base 100 moves downward, it will push the upper template 200 at the same time. Move down with the second drive column 230, the second column hole 511 matches the inclined structure of the second drive column 230, the inclination angle of the second drive column 230 is the same as the inclination angle of the inclined plane on the front side of the upper convex part 513, and the upper mold core 300 A second protrusion groove 310 matching the second protrusion 512 is provided. After the second side pusher 510 moves to the second protrusion groove 310 , the plastic between the second protrusion groove 310 and the second protrusion 512 The space is formed to form the side structure of the product. When the upper mold is pressed to the lower mold, the first convex groove 250 cooperates with the upper convex part 513 and the second driving column 230 cooperates with the second column hole 511, and the second side pusher 510 simultaneously The subject moves backward to complete the movement of the second convex part 512 to the molding cavity, so that the front side of the product can be smoothly formed. When the upper mold moves up, the second driving column 230 drives the second side pusher 510 to move forward to avoid Affect product release.

Furthermore, the upper mold core 200 is provided with a left mold core 260 and a right mold core 270 extending downwards, and the left mold core 260 and the right mold core 270 extend to the molding core 300 through corresponding openings. The cavity, the left mold core 260 and the right mold core 270 are used for partial molding of the product, which is beneficial to the molding of different products only when the same partial structure is different. When changing the local structure of the product, replace the left mold core 260 or the right mold core 270 to produce products with only partial structure differences, which saves production costs and has better flexibility.
