A mold for making bat and softball jerseys

Abstract

The invention discloses a baseball and softball coat making die. The die is formed by four hard die bodies arrayed in a cross manner, wherein a spherical die cavity is formed after the folding of the four die bodies; a left die body and a right die body are symmetrically arranged, and a front die body and a rear die body are symmetrically arranged; the left and right die bodies form a left and right die contact folding part at the upper portion of the folded die, and the left and right die bodies contact with the front and rear die bodies in a folding manner; the front and rear die bodies form a front and rear die contact folding part at the lower portion of the folded die according to a symmetric principle, and simultaneously the front and rear die bodies contact with the left and right die bodies in a folding manner; the folding parts of the four die bodies except the left and right die body folding part and the front and rear die body folding part are thread collars on the surface of a coat, and are provided with thread collar grooves corresponding to the thread collars on the surface of the coat; and a gap formed on each of the four dies becomes a die cavity exhaust port after the die locking. The die has the advantages of simple and easily-implemented coat shaping, simplified secondary processing operation, and great improvement of the baseball and softball coats.

Description

technical field [0001] The invention relates to a mold, in particular to a mold for making bats and softball jerseys. Background technique [0002] At present, the structure of the bat and the softball used in the official game is mainly composed of an elastic core part and a leather jersey coated outside the core. Cooperate figure 1 As shown, the jersey is made of two "8"-shaped sheets A butt-jointed and sewed to cover the ball core B to form a sphere. A thread collar is sewn at the butt-joint of the jersey to meet the shape requirements of the baseball and softball. The sewing of the thread collar is usually done manually, so it has high requirements for the workers' operating ability. However, under the premise that the labor cost of enterprises is increasing continuously, manual operation will inevitably increase the production cost of the product; in addition, leather jerseys The source of raw materials is limited, and the price of leather materials is high, which is ...

Problems solved by technology

Cooperate figure 1 As shown, the jersey is made of two "8"-shaped sheets A butt-jointed and sewed to cover the ball core B to form a sphere. A thread collar is sewn at the butt-joint of the jersey to meet the shape requirements of the baseball and softball. The sewing of the thread collar is usually done manually, so it has high requirements for the workers' operating ability. However, under the premise that the labor cost of enterprises is increasing continuously, manual operation will inevitably increase the production cost of the product; in addition, leather jerseys The source of raw materials is limited, and the price of leather materials is high, which is also the reason why it is difficult to reduce the price of the product, and then it is difficult to improve the competitiveness of the product market; moreover, the use of the two-piece butt-stitched jersey for the ball is restricted by the environment. When used in wet or rainy weather, the ball must be soaked in water from the seam of the jersey to the core, which will increase the weight of the ball, and the conductor core will be loose and deformed, which will affect the elastic coefficient of the ball, and the original physical properties of the ball cannot be guaranteed. characteristics, greatly reducing the service life of the sphere

[0003] Therefore, there have been spherical jerseys made of PU material, such as figure 2 , 3 As shown, it uses two buckle-shaped hemispherical molds 1' and 2' to form the jersey on the core. Although this method can realize the effect of mechanized production of jerseys to reduce labor costs, and use PU material to replace leather The material reduces the cost of materials, and at the same time achieves the function of good sealing and preventing water immersion; however, due to the influence of the shape of the mold, there will be a parting line 3' in the middle of the molded jersey, and the entire ball must be manually shaved. Meet the requirements of the shape of the sphere, so there is still the problem of cumbersome manufacturing process
