Manufacturing method for integral plastic tap body component and plastic tap body component

Abstract

The invention is suitable for a manufacturing method for an integral plastic tap body component and a product thereof. The manufacturing method mainly adopts the technical scheme of molding a tap by twice injection molding, wherein the primary injection molding is used for molding a first component on a middle connection part of the tap body component; the first component is placed into a mold toundergo secondary injection molding so as to mold a second component on both sides of the tap body component; the second component properly coats and connects the first component; and required holes are reserved as a water inlet, a water outlet and a valve seat. The technical scheme can simplify the complicated and lengthy manufacturing method of the conventional copper casting, improves production efficiency and product quality, reduces cost, reject ratio and product weight, and greatly reduces transportation cost. Compared with the conventional manufacturing method for forming the componentby individual injection molding and then sticking, the method can effectively reduce manual assembly cost, improves production efficiency and product quality, and ensures that the component has better structural strength.

Description

technical field [0001] The invention belongs to the field of a faucet manufacturing method and its finished products, and in particular relates to a method for manufacturing an integrated plastic faucet body component and a plastic faucet body component made by the method. Background technique [0002] The existing water outlet faucet assembly usually includes a faucet body component, especially a faucet body component with double water inlets, which is roughly H-shaped, including left and right valve seats, a connecting part between the valve seats, and The legs extending from the bottom of the valve seat; each of the bottom ends of the legs has a water inlet, which can be connected to the top valve seat through an internal flow channel, and the valve seat can be provided with a valve body for installation, and can be Each relative valve body is controlled by the rotation of a handle. In addition, the connecting part between the valve seats has an internal flow channel. The...

Problems solved by technology

[0003] It should be noted that there are generally two methods of manufacturing the above-mentioned faucet body components at present; the first method is to directly adopt the copper casting method, and its disadvantage is that it needs to produce sand cores and sand molds, and then cast through copper liquid. 1. Remove the sand core to complete the rough prototype, and then use subsequent mechanical processing, such as twisting, drilling, milling and other processing methods, to obtain the required faucet body components, so the entire manufacturing method is complicated and lengthy, resulting in processing The time is too long, the efficiency is not high, and the yield is low. In addition, the tool loss required for machining is large, which will also increase the production cost. At the same time, if the tool is not properly maintained or replaced, the accuracy of the processing size will also be affected. , which reduces the quality of the product; in addition, the copper material used in copper casting not only has a high cost of materials, but also has a high specific gravity, which also relatively increases the overall transportation cost, which is not economical and cost-effective.

Although such a manufacturing method can overcome the one-time injection molding of the flow channel in the middle connection part, it cannot solve the draft problem; therefore, the disadvantages of this faucet manufacturing method are: 1. After injection molding each component, a large amount of Manual gluing production, manual assembly costs are high, and production efficiency is relatively low; 2. Due to manual assembly operations at the same time, the assembly quality will be affected by the differences in the skills and proficiency of each operator, so the assembly quality cannot be effectively guaranteed; 3. The components are bonded to each other with adhesives, and the connection strength is relatively poor. The adhesives are prone to qualitative changes, resulting in the failure of the adhesive parts to be tightly bonded, which affects the quality and life of the product. In summary, the existing faucet body components There are many shortcomings in the production method, and there is a need for further improvement and innovation.
