Embodiment 1

[0050] Such as Figure 4 The embodiment shown is a method for making a baseball bat, which includes the following steps:

[0051] Step 100, clean the bead mold

[0052] Send the bead mold for bat bead molding to the stove, heat the bead mold to a temperature of 70℃, clean the inner surface of the mold with methyl ethyl ketone and mold cleaning agent, and then brush the sealing agent to make the inner surface of the mold Smooth and brush with release agent;

[0053] Step 200, baking the steel mandrel

[0054] In matching the shape of the baseball bat such as figure 1 The outer surface of the steel mandrel 1 shown is brushed with white silicone adhesive, and the steel mandrel is placed on the stove plate of the stove top for baking. When the surface of the steel mandrel is white, stop baking; figure 1 As shown, the end surface area of ​​the right end of the steel mandrel is larger than the end surface area of ​​the left end. Both ends of the steel mandrel are provided with an extension ...

Embodiment 2

[0078] In Example 2, such as Figure 5 As shown, there are spirally arranged conical protrusions on the outer circumference of the steel core rod. The distance between the conical protrusions in adjacent rows is 0.25 cm, and the height of the conical protrusions is 0.29 cm. The end surface area of ​​the right end of the steel mandrel is larger than that of the left end. Both ends of the steel mandrel are provided with extension rods 6 extending in the axial direction of the steel mandrel. The end of the extension rod at the right end is provided with a nut 7. The glass fiber in Example 1 was replaced with carbon fiber.

[0079] The other structures and steps of Embodiment 2 are the same as those in Embodiment 1.

Abstract

The invention discloses a baseball bat production method. According to the method, strip silicon sheets made of raw silicon materials are used as fillers, a steel core rod in the middle serves as a central support rod, the strip silicon sheets and the steel core rod are combined in a high density mode to form ball bat retaining strips through high-temperature forming of a retaining strip mold, thermal expansion of the strip silicon sheets is used for producing pressure to all layers of yarn materials to cure epoxy resin on all layers of the carbon fibers or glass fiber yarn materials. The method has the advantages of being high in repeated usage rate, capable of saving production costs, simple to form and operate, low in baseball bat coarse blank and scrap ratio, bubble-free in produced baseballs and uniform in wall thickness, high in strength and stable in quality of produced baseballs.

Description

Technical field [0001] The invention relates to the technical field of sports goods manufacturing, in particular to a method for manufacturing a baseball bat with high production efficiency, low cost, high strength, good quality stability, and uniform wall thickness. Background technique [0002] The traditional bat molding method is blow molding. An ultra-thin plastic film tube is placed in the bat preform. When the bat preform is formed, a certain wind pressure is applied to the sealing mouth to make the ultra-thin plastic film The tube supports the inner wall of the bat preform. [0003] The bat forming method in the prior art has the following disadvantages: [0004] 1. When molding by air-filling molding, when a certain wind pressure is applied to the ultra-thin plastic film tube, the ultra-thin plastic film tube is easily broken, causing wrinkles and air leakage in the bat. [0005] 2. When molding by the injection molding method, unstable wind pressure will cause uneven wall t...
