[0025] The following is combined with Figure 1-7 To further explain this application,

[0026] The embodiment of the present application discloses a charger injection molding mold that is convenient for material removal. Figure 1 and Figure 7, a charger injection molding production mold that is convenient for material removal, including an injection molding machine body 1, the injection molding machine body 1 includes a top plate 101, the bottom of the top plate 101 is fixedly connected to a bracket 102, the number of the brackets 102 is four, the bottoms of the four brackets 102 are commonly fixedly connected to a bottom plate 105, the top of the top plate 101 is fixedly connected to a hydraulic cylinder 110, the output end of the hydraulic cylinder 110 passes through the inner cavity of the top plate 101 and is fixedly connected to a moving rod 109, the bottom of the moving rod 109 is fixedly connected to an upper mold plate 106, the bottom of the upper mold plate 106 is movably connected to a lower mold plate 107, the inner cavities of the upper mold plate 106 and the lower mold plate 107 are both provided with injection grooves 114, the top of the upper mold plate 106 is connected to an injection port 108, and the front and rear sides of the upper mold plate 106 are fixedly connected to an ejection mechanism 2;

[0027] The ejection mechanism 2 includes a mounting block 201, one side of the mounting block 201 is fixedly connected to one side of the upper mold plate 106, the bottom of the mounting block 201 is fixedly connected to a connecting rod 202, there are two connecting rods 202, the inside of the two connecting rods 202 is commonly fixedly connected to a sliding rod 212, the surface of the sliding rod 212 is movably connected to the sliding block 203, one side of the sliding block 203 is fixedly connected to a linkage block 205, the top of the linkage block 205 is fixedly connected to a connecting block 206, the top of the connecting block 206 is fixedly connected to an ejection block 207, and the surface of the ejection block 207 is movably connected to the inner cavity of the lower mold plate 107.

[0028] Reference Figure 1 The surface of the upper mold plate 106 is fixedly connected with a guide block 104, and the number of the guide blocks 104 is four. The inner cavity of the guide block 104 is movably connected with a guide column 103. The top of the guide column 103 is fixedly connected to the bottom of the top plate 101, and the bottom of the guide column 103 is fixedly connected to the top of the bottom plate 105. The guide column 103 and the guide block 104 are arranged to limit and guide the upper mold plate 106 when it moves upward, so that the upper mold plate 106 will not be offset in position when it moves upward.

[0029] Reference Figure 2 The bottom of the upper mold plate 106 is provided with a limiting hole 111, and the number of the limiting holes 111 is four. The inner cavity of the limiting hole 111 is movably connected to the limiting block 112. The bottom of the limiting block 112 is fixedly connected to the top of the lower mold plate 107. By setting the limiting holes 111 and the limiting block 112, the position of the bottom of the upper mold plate 106 and the top of the lower mold plate 107 will not be offset when they contact, thereby improving the accuracy and quality of the subsequent injection molding operation.

[0030] Reference Figure 6A movable groove 113 is provided on the surface of the lower mold plate 107. The inner cavity of the movable groove 113 is movably connected to the surface of the ejector block 207. The shape of the ejector block 207 is consistent with the movable groove 113. Through the arrangement of the movable groove 113 and the ejector block 207, the model in the mold can be ejected by moving the ejector block 207 upward when the injection molding is completed, making it convenient for the staff to take it out.

[0031] Reference Figure 7 The surface of the sliding block 203 is provided with a sliding groove 211. The diameter of the sliding groove 211 is consistent with the diameter of the sliding rod 212. The inner cavity of the sliding groove 211 is movably connected to the surface of the sliding rod 212. Through the arrangement of the sliding groove 211 and the sliding rod 212, when the sliding rod 212 moves upward in the inner cavity of the sliding groove 211, it can indirectly drive the ejection block 207 to move upward, thereby ejecting the model;

[0032] Reference Figure 6 and Figure 7 , a fixed block 204 is fixedly connected to one side of the inner cavity of the lower mold plate 107, and there are two fixed blocks 204. A dovetail groove 209 is opened in the inner cavity of the fixed block 204, and a dovetail block 208 is movably connected to the inner cavity of the dovetail groove 209. The inner side of the dovetail block 208 is fixedly connected to the outer side of the ejection block 207. The dovetail groove 209 and the dovetail block 208 are arranged. Since the shape of the dovetail block 208 is consistent with the dovetail groove 209, and the dovetail block 208 is fixedly connected to the ejection block 207, the ejection block 207 will not be separated from the fixed block 204 when it moves up and down, thereby improving the stability of the ejection block 207 when it moves;

[0033] Reference Figure 6 and Figure 7 The bottom of the inner cavity of the lower mold plate 107 is fixedly connected to the limiting column 210, and the top of the limiting column 210 is movably connected to the bottom of the linkage block 205. Through the setting of the limiting column 210, when the ejection block 207 moves downward, it indirectly drives the bottom of the linkage block 205 to contact the top of the limiting column 210. At this time, the top of the ejection block 207 is just level with the top of the lower mold plate 107, so as not to affect the next injection molding operation.

[0034] Working principle: First, liquid plastic is injected through the injection port 108, and the liquid plastic will fill the interior of the injection groove 114. When the liquid plastic cools and takes shape, the output end of the hydraulic cylinder 110 drives the moving rod 109 to move upward, and the moving rod 109 drives the upper mold plate 106 to move upward, and the upper mold plate 106 drives the guide block 104 to slide on the surface of the guide column 103, and at the same time, the limit block 112 is separated from the inner cavity of the limit hole 111, and at the same time, the upper mold plate 106 drives the mounting block 201 to move upward, and the mounting block 201 drives the connecting rod 202 to move, and the connecting rod 202 drives the sliding rod 212 to move, and the sliding rod 212 drives the sliding block 2 03 moves upward, and then drives the linkage block 205 to move through the sliding block 203, drives the connecting block 206 to move upward through the linkage block 205, drives the ejection block 207 to move upward through the connecting block 206, and at the same time, the ejection block 207 drives the dovetail block 208 to move upward in the inner cavity of the fixed block 204, thereby ejecting the mold. When preparing for the next injection, the upper mold plate 106 is driven downward by the hydraulic cylinder 110, thereby driving the linkage block 205 to move downward until the bottom of the linkage block 205 contacts the top of the limit column 210. At this time, the top of the ejection block 207 is level with the top of the lower mold plate 107, and finally, the liquid plastic can be injected through the injection port 108 again.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
