[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] The present invention provides a floating coil head prefabrication mold as Figures 1-4 shown, which includes a base 6 and a die core 7 installed on the outer wall of the upper end of the base 6;

[0025] A fixing piece 5 is arranged on the upper side of the base 6;

[0026] The inner part of the fixing piece 5 is fixedly connected with a mold body 8 to form a mold cavity required for molding between the mold body 8 and the die core 7;

[0027] A counterweight 2 is arranged on the upper side of the fixing piece 5 to provide a downward pressure to limit the position of the fixing piece 5 on the base 6. An upper outer wall inside the mold body 8 is provided with a pouring port 9. During the production process of the floating coil head, first, the fixing piece 5 is placed on the base 6, so that the mold body 8 is sleeved on the die core 7 to form a mold cavity. Then, the raw material for making the head is dissolved at a high temperature into a raw material liquid, and the raw material liquid is poured into the mold cavity through the pouring port 9 through a specified container. When the raw material liquid is seen through the pouring port 9, stop pouring, and then place the counterweight 2 on the fixing piece 5. After waiting for the model in the mold cavity to cool, remove the counterweight 2 and the fixing piece 5 in sequence. After demolding the formed head and trimming the edge of the head, it can be waiting for inspection and warehousing;

[0028] A cover plate 12 is arranged on the upper side of the pouring port 9. The upper circular outer wall of the cover plate 12 is fixedly connected with a guide hopper 16 to guide the moving direction of the raw material liquid. A through hole 18 that penetrates up and down is opened inside the center of the cover plate 12 for the raw material liquid to flow into the pouring port 9. When pouring the raw material liquid through the pouring port 9, the cover plate 12 can be clamped inside the pouring port 9. When pouring the raw material liquid, it can enter the mold cavity through the through hole 18 under the guidance of the guide hopper 16, avoiding the situation of dripping on the mold body 8 and overflowing from the pouring port 9 during the process of pouring the raw material liquid.

[0029] As Figure 4As shown, a limiting block 17 is fixedly connected to the lower circular outer wall of the cover plate 12 to limit the position of the cover plate 12. A top plate 15 is provided on the upper side of the guiding hopper 16 to prevent impurities from entering the interior of the guiding hopper 16 during the cooling and forming process. A handle b14 is fixedly connected to the center of the upper outer wall of the top plate 15 to drive the movement of the top plate 15 under the action of an external force. A baffle 13 is fixedly connected to the lower outer wall of the top plate 15 to limit the position of the top plate 15 on the guiding hopper 16.

[0030] When limiting the position of the cover plate 12, the limiting block 17 can be clamped inside the pouring port 9 to limit the position of the cover plate 12. After pouring the raw material liquid, the top plate 15 can be buckled on the guiding hopper 16 under the limitation of the baffle 13 to prevent impurities from entering the raw material liquid to be solidified through the guiding hopper 16 during the cooling of the head, avoiding the situation of contaminating the raw material liquid and the need for secondary impurity removal during the recovery of the corner edges. At the same time, the top plate 15 can be removed by grasping the handle b14.

[0031] As Figure 4 shown, the guiding hopper 16 is inclined from top to bottom to guide the flow of the raw material liquid. The cover plate 12, the guiding hopper 16, and the limiting block 17 are integrally formed by pouring.

[0032] The inclined guiding hopper 16 can guide the raw material liquid to quickly enter the pouring port 9 for pouring operation, and the upper opening of the guiding hopper 16 is relatively large, which can prevent dripping during the pouring of the raw material liquid.

[0033] As Figure 1 and Figure 2 shown, a bottom plate 3 is fixedly connected to the lower outer wall of the counterweight block 2. Handle a1s are fixedly connected to the front and rear circular outer walls of the counterweight block 2 to drive the removal of the counterweight block 2 from the fixing member 5 under the action of an external force. A weight-reducing groove 4 is formed inside the circular outer wall of the fixing member 5 to reduce its own weight and provide a holding space. Clamping blocks 11 are fixedly connected to the upper and lower outer walls of the fixing member 5. Clamping grooves 10 for the clamping blocks 11 to be clamped are formed inside the upper outer wall of the base 6 and the lower outer wall of the bottom plate 3 to limit the position of the fixing member 5 on the base 6 and the position of the counterweight block 2 on the fixing member 5. A hole penetrating up and down is formed at the center of the counterweight block 2.

[0034] When assembling the counterweight block 2, the fixing member 5, and the base 6, first place the base 6 on a flat ground. Then, grasp the fixing member 5 through the weight-reducing groove 4 and move it onto the base 6. The clamping block 11 at the lower end of the fixing member 5 is clamped into the clamping groove 10 formed on the base 6 for position limitation. Then, after pouring the raw material liquid, grasp the handle a1 to move the counterweight block 2 to the upper side of the fixing member 5, and clamp it between the clamping block 11 at the upper end of the fixing member 5 and the clamping groove 10 formed at the lower end of the bottom plate 3 to limit the position of the counterweight block 2 on the fixing member 5.

[0035] As Figure 1 and Figure 2 shown, the mold core 7 and the mold body 8 share the same center of the circle, and the diameter of the mold body 8 is larger than that of the mold core 7 to form a molding cavity.

[0036] When the mold body 8 is buckled on the mold core 7, at this time, the arc-shaped mold body 8 and the mold core 7 share the same center of the circle, thereby forming a sufficiently smooth mold cavity to ensure that the size of each formed head is the same.

[0037] The implementation principle of this embodiment is as follows: In the process of manufacturing the floating coil head, first place the fixing member 5 on the base 6, so that the mold body 8 is sleeved on the mold core 7 to form a mold cavity. Subsequently, the raw material for making the head is dissolved at high temperature into a raw material liquid, and the raw material liquid is poured into the mold cavity through the pouring port 9 through a specified container. When the raw material liquid is seen through the pouring port 9, stop pouring. Then place the counterweight 2 on the fixing member 5. After waiting for the model in the mold cavity to cool, remove the counterweight 2 and the fixing member 5 in sequence. After removing the formed head from the mold, after trimming the edge of the head, it can be waiting for inspection and warehousing. When pouring the raw material liquid through the pouring port 9, the cover plate 12 can be clamped inside the pouring port 9. When pouring the raw material liquid, it can be guided by the guiding hopper 16 and enter the mold cavity through the through hole 18, so as to avoid the situation of dripping on the mold body 8 and overflowing from the pouring port 9 during the process of pouring the raw material liquid.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
