[0024] See also Figure 1-4 As shown, the utility model is an anti-overflow injection mold, including a main body 1, a fixed mold 2 is arranged at the lower end of the main body 1, a soft mold 3 is arranged on the upper surface of the fixed mold 2, a feeding pipe 4 is arranged at the upper end of the soft mold 3, a movable mold plate 5 is arranged at the middle end of the feeding pipe 4, a pushing rod 6 is arranged on one side of the upper end of the movable mold plate 5, a pushing motor 7 is arranged at the other end of the pushing rod 6, the pushing motor 7 is arranged on a fixed plate 8, and a feeding port 9 is arranged at the middle end of the fixed plate 8.
[0025] According to the above-mentioned feeding pipe 4, a fixed mold 2 is provided at the lower end, and the fixed mold 2 is fixed at the lower end of the main body 1. When the fixed mold is in operation, the fixed mold 2 will not move and will be stable enough. The movable mold plate 5 moves downward to reach the fixed mold 2. At this time, the material enters from the feeding port 9 for injection molding. A soft mold 3 is provided on the upper layer of the surface of the fixed mold 2 body. A movable mold plate 5 meshing therewith is provided on the upper end of the soft mold 3 so that the soft mold 3 will not flow out due to material overflow. When the material flows into the fixed mold 2, a pushing motor 7 is started. The pushing motor 7 drives a pushing rod 6 provided at one end to move up and down. When the pushing rod 6 moves up and down, it drives the movable mold plate 5 to move downward. The movable mold plate 5 moves downward and when it moves to the lowest end, the material is extruded to complete the injection molding. The movable mold plate 5 moves downward to inject the material. When the movable mold plate 5 is injected, sometimes there is too much material and the material will overflow. The anti-overflow port 101 ensures that the material will not flow out when it overflows.
[0026] In one embodiment, for the above-mentioned feed inlet 9, an anti-overflow opening 101 is provided at the outer bottom end of the feed inlet 9.
[0027] According to the above, when feeding through the feed port 9, the injection material sometimes overflows due to the vibration of the equipment, and the anti-overflow port 101 wraps the outside of the moving template 5. When the material overflows, it just blocks the material, and at this time the anti-overflow port 101 ensures that the material does not overflow to the outside of the equipment.
[0028] In one embodiment, for the above-mentioned movable template 5 , the movable template 5 body is provided with an anti-overflow strip 102 .
[0029] According to the above, the material is injected by moving the movable platen 5 downward. When the movable platen 5 is injecting, sometimes when there is too much material, the material will overflow. The anti-overflow port 101 ensures that the material will not flow out when it overflows.
[0030] In one embodiment, for the above-mentioned fixing plate 8 , a feed inlet 9 is provided at the middle end of the fixing plate 8 , and a protection port 103 is provided at the upper end of the feed inlet 9 .
[0031] According to the above-mentioned feed port 9 fixed at the middle end of the fixed plate 8, the fixed plate 8 is used to fix the feed port 9 to ensure that it is sufficiently stable when pouring materials into the inside. When the feed port 9 is feeding, it may sometimes contact other mechanical components. At this time, the protective port 103 at the upper end completely prevents other mechanical components from directly contacting the feed port 9.
[0032] In one embodiment, for the above-mentioned fixed mold 2 , the lower end of the fixed mold 2 is fixed to the lower end of the inside of the main body 1 .
[0033] According to the above, the fixed mold 2 is fixed at the lower end of the main body 1 and is stable enough not to move when the fixed mold is fixed, and moves downward through the movable mold plate 5 to reach the fixed mold 2. At this time, the material enters from the feed port 9 for injection molding.
[0034] In summary, with the help of the above technical solution of the utility model, the push motor 7 is started to drive the push rod 6 at one end to move up and down. When the push rod 6 moves up and down, it drives the movable template 5 at the other end. When the movable template 5 performs downward extrusion movement, it moves downward through the movable template 5 to reach the fixed mold 2. At this time, the material enters from the feed port 9 for injection molding. The feed port 9 is fixed at the middle end of the fixed plate 8. The fixed plate 8 is used to fix the feed port 9 to ensure that it is stable enough when pouring the material into the inside. When the feed port 9 is feeding, it sometimes contacts other mechanical components. At this time, the protective port 103 at the upper end completely avoids direct contact between other mechanical components and the feed port 9. When the material is injected by moving the movable template 5 downward, when the movable template 5 is performing injection molding, Sometimes when there is too much material, the material will overflow. The anti-overflow port 101 ensures that the material will not flow out when it overflows. When the material enters the fixed mold 2 through the feeding pipe 4 and is squeezed downward to the fixed mold 2 by the movable mold 5, the material is shaped by extrusion. Since the upper end surface of the fixed mold 2 is provided with a soft mold 3, the inside of the fixed mold 2 is sealed, so that the material will not overflow. If material overflows, an anti-overflow strip 102 is provided on the movable mold 5. The anti-overflow strip 102 prevents the material from flowing out. The material is injection molded by moving the movable mold 5 downward. When the movable mold 5 is injecting, sometimes when there is too much material, the material will overflow. The anti-overflow port 101 ensures that the material will not flow out when it overflows. After the injection molding is completed, it is taken out through the material preparation place 201 to complete all the injection molding work.
[0035] Through the above technical solution, 1. The injection mold can be completed through the movable platen. When various molds are needed, the injection molding of other shapes can be completed by simply adjusting the pattern on the surface of the movable platen.
[0036] 2. When the movable platen is pressed down when preparing the injection mold, anti-overflow ports and anti-overflow strips are arranged on the movable platen body to make the gap in the injection mold particularly tight and prevent overflow in the injection mold.
