Problems solved by technology

[0002] At present, the PVC balls manufactured by slush molding and rotational molding processes in the market are all single-layer structures, but the process of processing PVC balls with multi-layer structures is relatively complicated and the cost is high. Therefore, it is particularly important to solve this type of problem.

Embodiment 1

[0021] according to figure 1 As shown, the present embodiment provides a method for making a PVC ball with a multilayer structure, comprising the following steps:

[0022] Step 1: prepare the slurry of the soft and comfortable outer skin, the formula of the outer skin slurry is: 45% of PVC resin, 50% of plasticizer, 3% of auxiliary agent, The rest are coloring pigments;

[0023] Step 2: Prepare the inner layer ball skin slurry with high strength and strong support. The formula of the inner layer ball skin slurry is: 45% of PVC resin, 45% of plasticizer, and 3% of auxiliary agent , and the rest are coloring pigments;

[0024] Step 3: Inject the well-proportioned outer ball skin slurry into the vinyl or rotational molding mold and cover the mold locking screws, push the mold into the vinyl or rotational molding heating furnace body, and place it in the furnace body Heat and plasticize at medium temperature for 4 minutes, then pull the mold out of the furnace body and inject t...

Embodiment 2

[0028] A kind of manufacture method of the PVC ball of multilayer structure, comprises the following steps:

[0029] Step 1: Prepare the slurry of the soft and comfortable outer skin, the formula of the outer skin slurry is: 40% of PVC resin, 40% of plasticizer, 2% of auxiliary agent, The rest are coloring pigments;

Abstract

The invention discloses a manufacturing method of a PVC ball with a multilayer structure. A secondary injection structure is arranged at an inflation nozzle structure of a mold or at any position of aball; and in the process that liquid slurry of an outer-layer ball skin is injected into the mold for heating and forming for the first time, a secondary injection port designed on the mold is opened, liquid slurry of an inner-layer ball skin is injected into the mold again for secondary forming, and the outer-layer ball skin is integrated with the inner-layer ball skin so as to realize the functionality of the double-layer PVC ball.

Description

technical field [0001] The invention relates to the technical field of PVC balls, in particular to a method for manufacturing a PVC ball with a multilayer structure. Background technique [0002] At present, PVC balls manufactured by slush molding and rotational molding processes in the market are all single-layer structures, but the process of processing PVC balls with multi-layer structures is relatively complicated and the cost is high. Therefore, it is particularly important to solve this type of problem. Contents of the invention [0003] In view of the above problems, the present invention proposes a method for making a PVC ball with a multi-layer structure. By setting the structure design of the secondary injection at the inflatable nozzle structure of the mold or at any position of the sphere, the first outer layer of the ball skin of the mold is The liquid slurry is injected into the mold during heating and forming, and the designed secondary injection port on the...
