Referring to Figures 1-2, an embodiment provided by the present utility model: a secondary row position core-pulling structure, comprising a fixed mold 7, a hydraulic rod 1 is provided in the middle of the left inner wall of the fixed mold 7, and the left inner wall of the fixed mold 7 is provided with a hydraulic rod 1. A number of evenly distributed ejector pins 2 are provided, a movable die 3 is provided at the right end of the hydraulic rod 1, and a number of evenly distributed top blocks 13 are slidably connected in the middle of the movable die 3, and sliders 4 are provided on both the front and rear sides of the fixed die 7, The sliders 4 are all slidably connected to the inside of the chute 5, and the outer periphery of the chute 5 is provided with a sliding mold 8. Through the chute 5 and the slider 4, the sliding mold 8 can only move back and forth relative to the movable mold 3. To sum up, First, the first hydraulic rod 1 pulls the movable mold 3 to the left, so that the injection molded plastic part is separated from the fixed mold 7, and then the limit groove 9 on the sliding mold 8 is separated from the limit block 10. At the same time, the end of the fixed rod 14 Entering into the through groove 6, under the pulling of the moving mold 3, the sliding mold 8 slides to both sides respectively, thereby exposing the plastic parts, and the ejector pin 2 is located at the right end of the cavity 11, and then under the continuous pulling of the hydraulic rod 1 , the ejector rod 2 pushes the top block 13 out of the movable mold 3, and then pushes the plastic parts from the movable mold 3 up and down. After the core pulling is completed, the hydraulic rod 1 pushes the movable mold 3 to the right, and the movable mold 3 pushes the top block 13 first. Move to the right side at the same time, and then make the ejector pin 2 located on the left side of the cavity 11, and pull the top block 13 to the left, so that the top block 13 is retracted into the moving mold 3, and the sliding mold 8 acts on the fixed rod 14. Move downward and inward, and gradually disengage from the fixed rod 14, so that the limit block 10 is connected with the limit groove 9, and finally the fixed mold 7, the movable mold 3 and the sliding mold 8 together form a cavity, through the injection hole 12 to the cavity The material is injected inside the chamber and then compression molded to complete an injection cycle. Several process steps are completed at the same time through a hydraulic rod 1, which reduces the driving equipment of the core-pulling machine, making the equipment simpler, reducing production costs, and speeding up production efficiency. Operation Simple and easy to use

Fixed rods 14 are provided on the inner side walls of the front and rear sides of the middle of the fixed mold 7, and through grooves 6 are provided on the side of the sliding mold 8 close to the front and rear inner side walls of the fixed mold 7. The size of the fixed rod 14 and the through groove 6 are exactly the same. When the rod 14 enters the through slot 6, the fixed rod 14 is fixed, and under the action of the moving mold 3 being pulled to the left, the sliding mold 8 slides to both sides respectively, thereby exposing the plastic parts, and the fixed mold 7 is on the right. There is an injection hole 12 in the middle of the side. The fixed mold 7, the movable mold 3 and the sliding mold 8 together form a cavity. The injection hole 12 is used to inject material into the cavity and then compression molding. The top block 13 is provided with a cavity. 11. The inside of the cavity 11 is slidably connected with the ejector rod 2. When the hydraulic rod 1 pushes the movable mold 3 to the right, the movable mold 3 first pushes the top block 13 to move to the right, and then the ejector rod 2 is located in the cavity 11. On the left side, the top block 13 is pulled to the left side, so that the top block 13 is retracted inside the moving die 3, so that the right side surface of the moving die 3 is smooth without protrusions and depressions, and the injected slurry will not flow from the top block 13 and The joint of the movable mold 3 leaks out, the side of the sliding mold 8 away from the front and rear inner walls of the fixed mold 7 is provided with a limit slot 9, and the right inner wall of the fixed mold 7 is provided with limit blocks 10 on both sides, which are clamped by the limit blocks 10. Into the limit groove 9, so that the sliding mold 8 will not expand when grouting, which can make the quality of the injection molded plastic parts better.

Working principle: First, the first hydraulic rod 1 pulls the movable mold 3 to the left, so that the injection-molded plastic part is separated from the fixed mold 7, and then the limit groove 9 on the sliding mold 8 is separated from the limit block 10, and at the same time, the fixed The end of the rod 14 enters the inside of the through groove 6, and under the pulling of the moving mold 3, the sliding mold 8 slides to both sides respectively, thereby exposing the plastic parts, and the ejector rod 2 is located at the right end of the cavity 11, and then the hydraulic rod 1 Continue to pull down, the ejector rod 2 pushes the top block 13 out of the movable mold 3, and then pushes the plastic parts from the movable mold 3. After the core pulling is completed, the hydraulic rod 1 pushes the movable mold 3 to the right, and the movable mold 3 pushes first. The top block 13 moves to the right side, and then the ejector pin 2 is located on the left side of the cavity 11, and the top block 13 is pulled to the left side, so that the top block 13 is retracted into the moving mold 3, and the sliding mold 8 is on the fixed rod. Under the action of 14, it moves inward, and gradually separates from the fixed rod 14, so that the limit block 10 is connected with the limit groove 9, and finally the fixed mold 7, the movable mold 3 and the sliding mold 8 together form a cavity, through the injection hole 12 Injection into the chamber and then compression molding, to complete an injection cycle, through a hydraulic rod 1 to complete several process steps at the same time, reduce the driving equipment of the core-pulling machine, make the equipment simpler, reduce production costs, and speed up production Efficiency, simple operation and convenient use.

Finally, it should be noted that the above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. , it can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements to some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model, All should be included within the protection scope of the present invention.
