[0001] The utility model relates to the technical field of sports goods, and particularly relates to a mold for manufacturing a Pickleball racket and a Pickleball racket. Background Art

[0002] After retrieval, Chinese patent document CN115155026A discloses a Pickleball racket and a preparation method thereof. The Pickleball racket includes a racket body and a handle. The handle is connected to one side of the racket body. The racket body sequentially includes an upper panel, a lower panel, and a composite inner panel sandwiched between the upper panel and the lower panel from top to bottom. The composite inner panel is sequentially composed of an upper honeycomb panel, a shock-absorbing layer, and a lower honeycomb panel bonded from top to bottom. The upper honeycomb panel and the lower honeycomb panel are both provided with honeycomb structures. The upper panel and the lower panel are set as an integrally formed structure through a high-temperature forming preparation method and uniformly wrap the outside of the composite inner panel. A binding strip is uniformly arranged between the side edges of the composite inner panel and the upper panel and the lower panel. The above-mentioned Pickleball racket combines the use of panels and composite boards of different materials, thereby changing the structural characteristics such as the weight, vibration, and hardness of the racket board, so that it has a good grip feel, good shock-absorbing effect, and light weight.

[0003] Chinese patent document CN221106899U discloses a Pickleball racket using injection molding for edging, including a racket embryo. The racket embryo includes a racket body and a handle integrally connected to the racket body. A binding is formed by direct injection molding on the outer peripheral side of the racket embryo. When manufacturing, it includes the following steps: (1) Manufacture and prepare the racket embryo. (2) Install the racket mold on the injection molding machine and place the racket embryo into the racket mold. In the embodiment, the injection molding machine is a vertical injection molding machine to better perform injection molding edging on the racket embryo. (3) Put plastic particles into the injection molding machine to melt the plastic particles into a liquid state, and the liquid plastic flows into the racket mold and combines with the outer peripheral side of the racket embryo to form a binding. (4) After cooling, the binding is coated and fixed on the outer peripheral side of the racket embryo to form a finished product, and then the finished product is taken out of the racket mold.

[0004] Chinese Patent Document CN115228064A discloses an integrated Pickleball racket and a racket processing technology, including a first half racket body and a second half racket body processed by injection molding. After the first half racket body and the second half racket body are buckled, they are integrally formed by ultrasonic hot melting technology. Inner lining skeletons are provided on the inner sides of the first half racket body and the second half racket body. This processing technology quickly processes and forms the first half racket body and the second half racket body respectively by adopting an injection molding process. Moreover, during the processing of the two half racket bodies, the inner lining skeletons, convex columns, convex column sleeves, and hanging rope columns are formed simultaneously. Then, the two half racket bodies can be integrally welded and formed by ultrasonic hot melting technology, improving the processing efficiency of the Pickleball racket. The provided inner lining skeletons can increase the structural strength of the half racket body while increasing the feedback force when the spherical surface impacts the racket, and can also play a certain noise reduction role, increasing the overall quality sense and realizing the lightweight of the racket at the same time.

[0005] The prior art Pickleball rackets disclosed in the retrieved research, although there is also a disclosed injection molding edge wrapping structure in the prior art, such as CN221106899U, but it still needs to produce the initial embryo of the racket before further injection molding edge wrapping on this basis. And CN115228064A needs to first produce the first half racket body and the second half racket body, and then simultaneously complete the forming process of the inner lining skeleton, convex columns, convex column sleeves, and hanging rope columns. Its structure is relatively complex. And the racket body of CN115155026A includes an upper panel, a lower panel, and a composite inner panel sandwiched between the upper panel and the lower panel from top to bottom. The composite inner panel is successively composed of an upper honeycomb panel, a shock absorption layer, and a lower honeycomb panel bonded from top to bottom, which also makes it have a multi-layer composite structure layer.

[0006] Therefore, after retrieval, no prior art has been found to disclose the mold for making the Pickleball racket of the present application and the Pickleball racket, so there is this utility model. Summary of the Utility Model
