[0002] The badminton head is made of cork. There are two types of cork badminton heads. One is formed by grinding after stacking and bonding cork boards, and the other is formed by pressing cork particles. When using a mold to press and form the badminton head, processes such as filling and pressing the particles all take a lot of time, affecting the overall processing efficiency. Content of the Utility Model

[0003] To solve the deficiencies of the prior art, the utility model provides a double-layer pressing mold for a cork badminton head, which can increase the number of badminton heads formed at one time, share the filling and pressing time of the particles, and thus improve the production efficiency.

[0004] To achieve the above object, the utility model is realized through the following technical solutions:

[0005] A double-layer pressing mold for a cork badminton head includes a bottom plate. A limiting device is arranged outside the bottom plate. Below the bottom plate, a lower mold, a first middle mold, a second middle mold, a third middle mold, and an upper mold are sequentially arranged from bottom to top. A plurality of hemispherical mold cavities are arranged in an array on the top surfaces of the lower mold and the second middle mold. Filling cavities corresponding one by one to the hemispherical mold cavities below are arranged in an array on the first middle mold and the third middle mold. Pressing heads corresponding one by one to the filling cavities are arranged on the bottom surfaces of the second middle mold and the upper mold.

[0006] The limiting device includes limiting corners arranged at two top corners on one side edge of the bottom plate and a limiting edge arranged on the opposite side of this side edge.

[0007] Handles are arranged on the side edges of the lower mold, the first middle mold, the second middle mold, the third middle mold, and the upper mold.

[0008] The first middle mold and the third middle mold are exactly the same.

[0009] The pressing heads are detachably connected to the bottom surface of the second middle mold and the bottom surface of the upper mold.

[0010] The hemispherical mold cavities on the top surfaces of the lower mold and the second middle mold are arranged in multiple rows, and adjacent two rows of hemispherical mold cavities are arranged in a staggered manner.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model realizes the pressing and forming of multiple rows of badminton ball heads in the upper and lower layers through the stacking of molds. Through this structural design, the number of ball heads formed at one time is increased, the filling and pressing time of particles are shared, and the forming efficiency of the ball heads is greatly improved.

[0013] The top surface of the second middle mold of the utility model serves as the ball head forming mold, and the bottom surface of the second middle mold serves as the pressing mold for the lower layer of ball heads. Thus, through the integration of the hemispherical mold cavity and the pressing head, the structure is streamlined, and the total height and total weight of the mold are reduced.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In combination with the drawings and specific embodiments, the present utility model will be further described. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by this application.

[0021] As Figures 1-5 shown, the double-layer pressing mold for the cork badminton ball head of the present utility model includes a bottom plate 1, and a limiting device 10 is arranged outside the bottom plate 1. The limiting device 10 can position the molds stacked thereon, thereby ensuring the corresponding installation of each mold and ensuring the stable forming of each badminton ball head.

[0022] Above the bottom plate 1, a lower die 2, a first middle die 3, a second middle die 4, a third middle die 5 and an upper die 6 are sequentially arranged from bottom to top. A number of hemispherical die cavities 7 are arranged in an array on the top surfaces of the lower die 2 and the second middle die 4. The hemispherical die cavities 7 serve as the shaping cavities for the shuttlecock heads, and the processing of the shuttlecock heads is completed through pressing and forming.

[0023] Filler cavities 8 corresponding one by one to the hemispherical die cavities 7 below are arranged in an array on both the first middle die 3 and the third middle die 5. When the shuttlecock heads are pressed and formed, the filler cavities 8 are superposed on the hemispherical die cavities 7 as the accommodating cavities for the granular materials. Pressing heads 9 corresponding one by one to the filler cavities 8 are arranged on the bottom surfaces of the second middle die 4 and the upper die 6. After stacking the various dies, by pressing with a press, the pressing heads 9 are pressed into the filler cavities 8 to extrude the granular materials, so that the granular materials are extruded into the hemispherical die cavities 7 for final forming.

[0024] The bottoms of the lower die 2, the first middle die 3 and the second middle die 4 of this device are the lower forming components, and the top of the second middle die 4, the third middle die 5 and the upper die 6 of this device are the upper forming components. When processing, first stack the lower die 2 and the first middle die 3 on the bottom plate 1 in sequence, so that the filler cavity 8 of the first middle die 3 corresponds to the hemispherical die cavity 7 of the lower die 2, then fill the granular materials into the filler cavity 8 of the first middle die 3 to make the granular materials flush with the filler cavity 8. Subsequently, stack the second middle die 4 on the first middle die 3 so that the pressing head 9 on the bottom surface of the second middle die 4 corresponds to the filler cavity 8. Subsequently, stack the third middle die 5 on the second middle die 4 so that the filler cavity 8 of the third middle die 5 corresponds to the hemispherical die cavity 7 on the top surface of the second middle die 4, and then fill the granular materials into the filler cavity 8 of the third middle die 5. Finally, stack the upper die 6 on the third middle die 5 so that the pressing heads 9 of the upper die 6 correspond one by one to the filler cavities 8. After completing the assembly of the filler and the dies, use a press to press the upper die 6, and press and form the shuttlecock heads of the upper and lower layers through the pressing heads 9. Through the structural design of the upper layer of this device, the number of formed shuttlecock heads is increased, and the preparation time is shared, thereby improving the forming efficiency of the shuttlecock heads. Specifically, the first middle die 3 and the third middle die 5 are completely the same, the top surfaces of the lower die 2 and the second middle die 4 are completely the same, and the bottom surface of the second middle die 4 and the upper die 6 are completely the same.

[0025] The limiting device 10 includes limiting folding corners 11 arranged at two top corners on one side edge of the bottom plate 1 and a limiting edge 12 arranged on the opposite side of this side edge. The triangular positioning structure can enable the various dies to be stably stacked together to complete the pressing and forming.

[0026] Specifically, the bottom surface of the hemispherical die cavity 7 has through holes, and air can be discharged through the through holes to ensure the forming quality when pressing the shuttlecock head.

[0027] Specifically, handles 20 are provided at the sides of the lower die 2, the first middle die 3, the second middle die 4, the third middle die 5 and the upper die 6. The provision of the handles 20 makes it more convenient to transfer and stack the dies.

[0028] Specifically, the pressing head 9 is detachably connected to the bottom surface of the second middle die 4 and the bottom surface of the upper die 6. The installation method of the pressing head 9 is plugging or screw fixing. Through the detachable method, the pressing head can be easily replaced to meet the requirements of maintenance and servicing.

[0029] Specifically, multiple rows of hemispherical die cavities 7 are provided on the top surfaces of the lower die 2 and the second middle die 4, and two adjacent rows of hemispherical die cavities 7 are arranged in a staggered manner. Correspondingly, the filling cavities 8 on the first middle die 3 and the third middle die 5 are also arranged in a staggered manner, and the pressing heads 9 at the bottoms of the upper die 6 and the second middle die 4 are also arranged in a staggered manner. Through the setting of the staggered structure, more forming cavities can be provided within the same area, thereby improving the forming density and the processing efficiency.
