JPS58124622A - Hollow forming method of spherical body - Google Patents

Abstract

PURPOSE:To obtain an integrally formed hollow body composed of 2 airtight hollow chambers and a piercing hole provided in the center between them which is useful as a float for fishing by such an arrangement wherein 2 pieces of parison are hung down at both sides of a core metal mold, after metal molds are closed, they are inflated by blowing air into them. CONSTITUTION:Two pieces of ABS resin parison 9 are extruded along both side of a core metal mold 4 from a die 8 and metal molds 1 having a cavity 2 are closed. An air nozzle 6 is inserted through a hole 3 and parison at both sides is inflated and fused into one body, and the nozzle 6 is pulled out before parison is solidified and by this, float for fishing having a rope hole in the center is obtained. EFFECT:Problems of breakage, water infiltration, etc. which have occurred in the conventional float made by adhering extrusion molded parts together have been solved.

Description

DETAILED DESCRIPTION OF THE INVENTION This fly beak is related to a novel hollow structure #1 droplet of synthetic m** body mainly used for floats.

A through hole is provided along the central axis of the main body, and independent loop hollows are formed on both sides of the body.

For example, the 1- or oval-shaped spheres used as floats for fishing nets are made from the royal cow's body. The layers were joined together to form a single float.This is the rice paddies.
The main idea is to form a through hole in the axial direction of the ball stop length and separate airtight hollows *1 inside each side of the hole. It was considered a screw. Therefore, we had no choice but to injection mold each half of the noodle and immerse the C part in a single piece to make a float molded product. However, the float formed by the above-mentioned O stratified flow is
If you use it as a p child, there is a risk that the water pressure in the moss will cause a tortoise to occur in the Sankin Is, and the water will intrude into the middle of the storm, or the school will be demolished, causing a loss of W1, a.
