Abstract

A process for fabricating an integral plastic faucet member and a finished product thereof are provided. The process mainly includes two injection steps. A first plastic injection is used to mold a first part at a middle connecting part of a faucet member. The first part is then placed into a mold for a second plastic injection so as to mold a second part at two sides of the faucet member. The second part is properly wrapped around and bonded to the first part. Meanwhile, desired holes are reserved to serve as water inlets, water outlets, and valve seats. Through such a two-injection process, the conventional complicated and time-consuming copper casting process is simplified, which improves the production efficiency and product quality, lows the cost and defective ratio.
Meanwhile, the product weight is also reduced, which greatly reduces the transportation cost.

Claims (15)

1. A process for fabricating an integral plastic faucet member, comprising:
a. a first plastic injection molding step:

for integrally molding a hollow first part, wherein each of two ends of the first part has an inner water inlet, a flow passage being communicated between the inner water inlets, and the flow passage having at least one inner water outlet at a predetermined position;

b. a step of taking out and positioning the first part:

for taking out the molded first part and positioning the first part in a mold;
and c. a second plastic injection molding step:

for integrally wrapping a second part around the first part, wherein the second part at least comprises a wrapping part and two valve seat parts, the wrapping part being integrally wrapped around an outer surface of the first part and having an outer water outlet in communication with the inner water outlet of the first part, the valve seat parts being respectively integrally connected to two ends of the wrapping part, each valve seat part having a mounting groove, and the mounting grooves being respectively in communication with the inner water inlets at the two ends of the first part, such that the second part is adaptably integrally wrapped around the first part to perform the integral plastic faucet member.
2. The process for fabricating an integral plastic faucet member according to claim 1, wherein the first plastic injection molding step and the second plastic injection molding step use the same mold, the mold comprising a first mold cavity and a second mold cavity, the first mold cavity being used for molding the first part, and the second mold cavity being used for positioning the first part therein and wrapping the second part around the first part.
3. The process for fabricating an integral plastic faucet member according to claim 2, wherein the plastic injection molding in the first mold cavity and the second mold cavity is synchronously performed in the mold at the same time.
4. The process for fabricating an integral plastic faucet member according to claim 1, wherein the step of taking out and positioning the first part is achieved by using a manipulator to clamp and move the first part.
5. The process for fabricating an integral plastic faucet member according to claim 1, wherein the first plastic injection molding step and the second plastic injection molding step use glass fiber mixed with nylon as a plastic molding material.
6. The process for fabricating an integral plastic faucet member according to claim 1, wherein the second part integrally wrapped around the first part in the second plastic injection molding step further comprises two support leg parts, the support leg parts respectively integrally extending from bottom ends of the valve seat parts, each support leg part having a flow passage therein, the flow passages being respectively in communication with the mounting grooves of the corresponding valve seat parts, and an outer water inlet being formed on each of the flow passages at bottom end of each of the support leg parts.
7. The process for fabricating an integral plastic faucet member according to claim 6, wherein outer peripheral walls of the support leg parts are integrally injection molded with external threads for thread engagement at the same time in the second plastic injection molding step.
8. The process for fabricating an integral plastic faucet member according to claim 6, after the second plastic injection molding step, the process further comprising a step of preforming and engaging copper members, wherein two copper members preformed with external threads and outer peripheral walls of the support leg parts are respectively engaged with and fixed to each other, such that the outer peripheral walls of the support leg parts have copper external threads.
9. The process for fabricating an integral plastic faucet member according to claim 1, after the second plastic injection molding step, the process further comprising a step of preforming and mounting copper support leg parts, wherein two copper members preformed as the support leg parts are respectively mounted at bottom ends of the valve seat parts of the second part.
10. A finished product of an integral plastic faucet member, comprising:

a first part, integrally injection molded from a plastic material and being hollow strip-shaped, each of two ends of the first part having an inner water inlet, a flow passage being communicated between the inner water inlets, and at least one inner water outlet in communication with the flow passage being disposed at a predetermined position of the flow passage; and a second part, being wrapped around the first part through integral injection of a plastic material and at least comprising a wrapping part and two valve seat parts, the wrapping part being integrally wrapped around an outer surface of the first part and having at least one outer water outlet in communication with the inner water outlet of the first part, the valve seat parts being integrally connected to two end sides of the wrapping part, each valve seat part being formed with a mounting groove, and the mounting grooves being respectively in communication with the inner water inlets at the two ends of the first part.
11. The finished product according to claim 10, wherein the second part further comprises two support leg parts, the support leg parts respectively integrally extending from bottom ends of the valve seat parts, each support leg part having a flow passage therein, the flow passages being respectively in communication with the mounting grooves of the corresponding valve seat parts, and an outer water inlet being formed on each of the flow passages at the bottom end of each of the support leg parts.
12. The finished product according to claim 11, wherein outer peripheral walls of the support leg parts are integrally plastic injection molded with external threads for thread engagement.
13. The finished product according to claim 11, wherein the outer peripheral wall of each support leg part is engaged with and fixed to a copper member, and outer peripheral walls of the copper members have external threads.
14. The finished product according to claim 10, wherein the second part further comprises two support leg parts, the support leg parts being preformed from a copper material and then being respectively mounted at bottom ends of the valve seat parts.
15. The finished product according to claim 10, wherein the first part and the second part are integrally injection molded from a plastic material of glass fiber mixed with nylon.
