Injection molding can also be divided into injection molding and die casting. In the injection molding process, in order to inject the object into the desired shape, the injection mold is an indispensable item. Different molds are composed of different parts. When the existing injection mold is used to inject objects, some injection molded parts exist: as shown in the attached manual. Figure 1 The injection molded part body 4 shown in the figure has a penetrating hinge hole 41 formed thereon, which is often difficult to be injection molded in one step.

[0026] Embodiment 1

[0027] Please refer to Figures 1-8As shown, one of the purposes of this embodiment is to provide an injection molding mechanism for performing transverse hinge molding on an injection molded part using an injection mold, including an injection mold base 1, a mounting base 2 fixedly provided on the top of the injection mold base 1, an injection molded part body 4 located outside the top of the mounting base 2, a moving mechanism 3 provided inside the mounting base 2, the moving mechanism 3 is used to assist the injection molded part body 4 in forming a hinge hole 41, the moving mechanism 3 includes an inclined top 31 and a straight top 32 slidably connected to the inside of the mounting base 2, the top of the straight top 32 matches the shape of the top of the mounting base 2, a protrusion 311 is fixedly provided on the side wall of the inclined top 31 near the top, and the protrusion 311 is provided on the inclined top 31 On the side away from the straight top 32, the protrusion 311 corresponds to the position of the hinge hole 41. Before the injection molded body 4 and the mounting seat 2 are demoulded, the protrusion 311 is located inside the hinge hole 41. When the injection molded body 4 is injected, the top of the straight top 32 matches the shape of the top of the mounting seat 2. At this time, the inclined top 31 and the protrusion 311 are at a position away from the straight top 32. During the injection molding process of the injection molded body 4, the setting of the protrusion 311 forms the hinge hole 41 on the injection molded body 4, thereby realizing one-time injection molding of the injection molded body 4, without the need for subsequent drilling of the injection molded body 4, and improving the injection molding efficiency of the injection molded body 4.

[0028] Since the protrusion 311 is located inside the hinge hole 41, and the hinge hole 41 is sealed all around, and the hinge hole 41 is horizontally arranged and perpendicular to the direction of demoulding of the injection molded part body 4, when the injection molded part body 4 is demoulded, the protrusion 311 will pull the injection molded part body 4, making it difficult to demould the injection molded part body 4. In order to facilitate the subsequent removal of the injection molded part body 4, a slanted top fixing seat 21 is fixedly provided at the bottom of the mounting seat 2, and the slanted top 31 is slidably connected to the inside of the slanted top fixing seat 21. The mounting seat 2 and the slanted top fixing seat 21 are provided with interconnected slanted grooves. The top is inclined toward the direction close to the straight top 32, the inclined top 31 is slidably connected to the inside of the inclined groove, and the inclined top 31 moves obliquely along the axis of the inclined groove. A vertical groove is provided vertically through the interior of the mounting seat 2, and the straight top 32 is slidably connected to the inside of the vertical groove, and the straight top 32 moves vertically along the axis of the vertical groove. The straight top 32 is set in an inverted L shape, and the top of the inclined top 31 fits the outer surface of the straight top 32. Before the injection molded body 4 is demoulded, the top of the inclined top 31 is completely on the lower side of the straight top 32. When the injection molded body 4 is completed, the mold is opened and the injection molded body 4 is lifted upward so that the injection molded body 4 moves toward The cam 311 is located inside the hinge hole 41, and the inclined top 31 is driven to move upward during the rising process of the injection molded body 4, and the top of the inclined top 31 is in contact with the straight top 32, so that the straight top 32 is driven to rise along with the injection molded body 4 through the inclined top 31. Because an inclined groove for the movement of the inclined top 31 is provided inside the inclined top fixing seat 21, when the inclined top 31 rises along the inclined groove, the inclined top 31 moves toward the direction close to the straight top 32 under the action of the inclined groove. During the sliding process of the inclined top 31, the cam 311 moves in the direction away from the hinge hole 41. , so that the protrusion 311 is pulled out from the inside of the hinge hole 41, so that the protrusion 311 and the inclined top 31 are separated from the injection molded part body 4, thereby making it easier for the staff to remove the injection molded part body 4. After the protrusion 311 is disengaged from the hinge hole 41, the protrusion 311 moves to the lower side of the top of the straight top 32. At this time, the protrusion 311 will not block the upward movement of the injection molded part body 4, ensuring the demoulding of the injection molded part body 4. When the injection molded part body 4 is separated from the inclined top 31, under the action of gravity, the inclined top 31 and the straight top 32 move downward to return to their original positions, facilitating the subsequent use of the injection mold base 1 and the moving mechanism 3.

[0029] The cam 33 is fixed on the top of the cam 31 and the top 32, and the cam 33 is fixed on the top of the cam 31 and the top 32. The cam 33 is fixed on the top of the cam 31 and the top 32, and the cam 33 is fixed on the top of the cam 31 and the top 32. The cam 33 is fixed on the top of the cam 31 and the top 32, and the cam 33 is fixed on the top of the cam 31 and the top 32. The cam 33 is fixed on the top of the cam 31 and the top 32. The cam 33 is fixed on the top of the cam 31 and the top 32. The cam 33 is fixed to the upper and lower parts of the frame 31 so that the upper and lower parts of the frame 31 can be fixed to the upper and lower parts of the frame 31 by the support rod 31 and the support rod 32.

[0030] In summary, the working principle of this solution is as follows: when the moving mechanism 3 is in the initial state, the top of the straight top 32 matches the shape of the top of the mounting seat 2. At this time, the top of the inclined top 31 and the protrusion 311 are located inside the mounting seat 2 away from the straight top 32. The injection mold base 1 and the upper mold are combined for injection molding. During the injection molding process of the injection molded body 4, the setting of the protrusion 311 forms a hinge hole 41 on the injection molded body 4, thereby realizing one-time injection molding of the injection molded body 4. After the injection molding of the injection molded body 4 is completed, the upper mold is removed and the injection molded body 4 is lifted upward to move the injection molded body 4 in the direction away from the mounting seat 2. Since the protrusion 311 is located at the hinge hole 41, the upper mold is moved upward to move the injection molded body 4 away from the mounting seat 2. Inside the hole 41, the inclined top 31 and the straight top 32 are driven to move upward during the rising process of the injection molded part body 4. While the inclined top 31 rises along the inclined groove, the inclined top 31 moves toward the direction close to the straight top 32 under the action of the inclined groove, thereby pulling the protrusion 311 out of the hinge hole 41, so that the protrusion 311 and the inclined top 31 are separated from the injection molded part body 4, making it convenient for the staff to remove the injection molded part body 4. After the injection molded part body 4 is separated from the inclined top 31, under the action of gravity, the inclined top 31 and the straight top 32 move downward, and at the same time, the inclined top 31 descends along the inclined groove away from the straight top 32, so that the inclined top 31 and the straight top 32 return to their original position, which is convenient for the injection molding of subsequent injection molded parts.
