At the same time, the blade assembly is pushed to rotate by the coolant, and the guide block is rotated up and down under the cooperation of the first magnetic part and the second magnetic part, thereby changing the spraying direction of the coolant, so that the plastic product dissipates heat evenly, and avoids the coolant from flowing down the side wall of the lower mold cavity after absorbing heat, and its heat absorption efficiency is reduced, thereby improving the molding rate of the plastic product, and avoiding quality problems of the plastic product due to uneven cold and heat.

[0008] Preferably, guide cavities are respectively provided at the upper and lower parts of the guide block, and through openings are respectively provided at both sides of the guide cavity, and the coolant flows inside the guide cavity through the through openings.

[0015] (III) Beneficial effects

[0016] The present invention provides a rapid demolding mold for manufacturing plastic products on the surface of fitness equipment. It has the following beneficial effects:

[0018] (ii) The mold for the rapid demolding of the plastic product on the surface of the fitness equipment is manufactured. When the guide block rotates up and down, the counterweight block moves to push the sealing plate away from the through-hole, so that the coolant is sprayed through the through-hole to the lower mold cavity corresponding to the horizontal direction of the guide block, thereby avoiding the generation of cooling dead corners, making the plastic product evenly heated, and improving the quality of the plastic product.

[0019] (III) The mold for the plastic product on the surface of the fitness equipment is quickly demolded. The heat expansion block expands due to heat, pushing the heat dissipation pipe to rotate.

[0020] (IV) The mold for the plastic product on the surface of the fitness equipment is quickly demolded. When the coolant acts on the rotating blades, an impact force is generated. The impact force on the rotating blades is absorbed by the elastic absorption strip, thereby preventing the rotating blades from breaking due to excessive water flow rate.

[0021] (V) The mold for the plastic product on the surface of the fitness equipment is quickly demolded. When the blade assembly rotates, the centrifugal force generated by it pushes the cleaning plate to move on the rotating blade, and after it stops rotating, it returns to its original position through the third elastic member, thereby cleaning the scale on the rotating blade and preventing the rotating blade from breaking due to excessive weight during rotation.
