Abstract

A plastic faucet body and a die for molding the same are disclosed in present invention. The plastic faucet body comprises a left water inlet pipe ( 1 ) and a right water inlet pipe ( 2 ), wherein a connecting cross-beam ( 3 ) is disposed between the left water inlet pipe ( 1 ) and the right water inlet pipe ( 2 ), the left water inlet pipe ( 1 ) and the right water inlet pipe ( 2 ) are embedded with a threaded copper pipe ( 4 ), respectively, the copper pipes ( 4 ) are formed integrally with the plastic faucet body by means of a single stage process and are in communication with the corresponding left water inlet pipe ( 1 ) and the right water inlet pipe ( 2 ), respectively.

First claim

The invention claimed is:

1. A die for molding a plastic faucet body comprising:
a fixed mold, a movable mold, and
a mold-core installing seat,
wherein the mold-core installing seat is provided with a left water inlet mold core, a right water inlet mold core and a water outlet mold core;
wherein a working surface of the fixed mold is provided with a first injection molding cavity and a working surface of the movable mold is provided with a second injection molding cavity;
wherein the first injection molding cavity and the second injection molding cavity are cooperated to form an injection molding cavity and the injection molding cavity comprises a flow passage and a product molding cavity;
wherein the left water inlet mold core, the right water inlet mold core and the water outlet mold core of the mold-core installing seat are provided within a cavity corresponding to the product molding cavity, the second injection molding cavity is provided with a right side core-pulling hole and the right side core-pulling hole is provided with a left water inlet channel core-pulling rod;
wherein the first injection molding cavity is provided with a left side core-pulling hole and the left side core-pulling hole is provided with a right water inlet channel core-pulling rod, and
wherein the left water inlet channel core-pulling rod is configured to form a left core-pulling channel communicated with the left water inlet channel, and the right water inlet channel core-pulling rod is configured to form a right core-pulling channel communicated with the right water inlet channel, a distance between each end face of the left core-pulling channel and the right core-pulling channel and the axis of the water outlet is equal to the outer diameter of the water outlet, each of the right water inlet pipe and the left water inlet pipe is parallel to the axis of the water outlet.

2. The die according to claim 1 , wherein a plurality of fixed molds and a plurality of movable molds are provided at intervals in a horizontal plane.

3. The die according to claim 2 , wherein each of the fixed molds and the movable molds is provided with two working surfaces, and
wherein one working surface is provided with a first injection molding cavity, and another working surface is provided with a second injection molding cavity.
