Abstract
The invention discloses a process for producing a water faucet assembly. The process comprises the following steps: (a) performing injection molding on a plastic shell of the water faucet assembly; (b) performing injection molding on an inner runner of the water faucet assembly; (c) assembling the plastic shell and the inner runner; (d) filling the area beyond the inner runner in the plastic shell; and (e) performing glossiness treatment on the plastic shell. The process disclosed by the invention has the beneficial effects that (1) the provided process for producing the water faucet assembly is simple in process and low in cost; and (2) the produced water faucet assembly is high in quality and can be favorably compared with metal parts.
Description
Technical field
The invention belongs to hot-water heating part production field, be specifically related to a kind of faucet assembly production technology.
Background technology
Tap widely uses in daily life, and existing tap is generally metallic article, and this kind of metal faucet assembly generally by mould molding, then obtains finished product after the process such as polishing plating.As everyone knows, the fee of material of metallic article is high, and the percent defective of metallic article is high in casting process, more adds the cost of metal faucet assembly.
At present, also the production technology of the faucet assembly of some non-metallic material is suggested, as Chinese invention patent (CN103291994) discloses a kind of preparation technology of tap, by first preparing metal insert, again this metal insert location is carried out injection moulding in a mold and obtain plastic faucet idiosome, and then obtain plastic faucet.This preparation technology is more convenient, but still has metal assembly, therefore cost also can reduce further, in addition, because the intensity of plastics, density ratio metal are little, the method also also exists the shortcomings such as plastic faucet weigh light, intensity is little, be difficult to the metal faucet that matches in excellence or beauty, be not enough to attract consumer.
Summary of the invention
For deficiency of the prior art, the invention provides a kind of faucet assembly production technology, cost is low, technique is simple, and the similar metal goods that can match in excellence or beauty.
The present invention is achieved through the following technical solutions.
A kind of faucet assembly production technology, comprises the following steps: the plastic casing of a. injection mo(u)lding faucet assembly; B. the inner flow passage of injection mo(u)lding faucet assembly; C. described plastic casing and inner flow passage are assembled; D. the region outside inner flow passage in plastic casing is filled; E. glossiness process is carried out to plastic casing.
The invention provides the technique that a kind of plastic assembled part is assembled into faucet assembly, instead of originally loaded down with trivial details metalwork molding process, reduce cost and avoid the low deficiency of metal casting product rate.In addition, there is the shortcoming of weigh light, feel difference in traditional injection moulding part, particularly outstanding when this shortcoming is embodied on faucet assembly, and when tap component is lighter, operate poor stability, and intensity is not enough, and impact uses sensation.Existing plastics hot-water heating part cannot overcome this shortcoming.After plastic casing and inner flow passage being fitted together in the present invention, between two kinds, also leave space, in these spaces, add the quality that filler both can increase the rear product of assembling, turn increase product strength, and inner flow passage is wherein provided a supporting role.Finally glossiness process is carried out to plastic casing, make the quality of product and use feel to have very large lifting, very micro-with metallic article difference.
As preferably, in described step c, comprise following fine division step: inner flow passage is arranged on fixture block by c1.; C2. the fixture block this being provided with inner flow passage is placed in plastic casing and is fixed.
Because the caliber of inner flow passage is less than plastic casing, therefore need fixture block first to be fixed by inner flow passage, fixture block can be stuck in the inwall of plastic casing, is conveniently assembled together with inner flow passage and plastic casing by fixture block.
As preferably, in described fine division step c2, described fixture block is connected by cold welding technique with plastic casing.Pass through cold welding technique, the thermal stress deformation of the macromolecular materials such as plastics can be avoided well, promote the good attachment of material, resistance to compression and the combination property such as anticorrosive simultaneously, the instructions for use of various part of appliance can be met to greatest extent, and cost is low, safe and reliable.
As preferably, in described step e, described glossiness processing mode is plating.Traditional metalwork needs to carry out the PROCESS FOR TREATMENT such as polishing, plating to its surface, thus obtains bright and clean surface, complex procedures, and yields is not high; The plating yield rate of working of plastics is high, especially for plastics such as ABS, ABS+PC, PA.
As preferably, described filler is be selected from one in cement, steel sand, resin or its mixture.This kind of filler of cement, steel sand, resin can solidify after filling gradually, is fixed in a plastic housing by inner flow passage, good stability after solidification, and can provide enough intensity and weight, supporting plastic shell better after solidification.
Compared with prior art, the present invention has following beneficial effect: 1) provide a kind of faucet assembly production technology, technique is simple, cost is low; 2) the faucet assembly quality produced is good, can match in excellence or beauty with metalwork.

Fig. 2 is inner flow passage schematic diagram of the present invention.
Fig. 3 is sectional view of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the invention will be further described.
See Fig. 1 to Fig. 3, this faucet assembly comprises valve 11, delivery port 12, also comprises plastic casing 1, is provided with two inner flow passages 2 in this plastic casing 1.As can be seen from Figure 2, inner flow passage 2 is fixed in plastic casing 1 by the fixture block 3 being connected to its upper and lower two ends, in the residual cavity in plastic casing 1, is filled with filler.
Production technology of the present invention is as follows.
A. the plastic casing 1 of injection mo(u)lding faucet assembly.Plastics Shooting Technique is simple, technology maturation, and plastics injection moulding cost is more much lower than producing metal casting.Plastic casing 1 in the present invention is ABS material preferably, also can be the materials such as ABS+PC, PA, and this kind of material, owing to having certain electric conductivity, can simplify the electroplating technology operation in later stage.
B. the inner flow passage 2 of injection mo(u)lding faucet assembly.Select the plastic material of level of security, be injection molded into runner, flow through for fluid.Inner flow passage 2 can have one also can arrange many as required, such as in order to meet the demand of logical cold water and logical hot water.
C. described plastic casing 1 is assembled with inner flow passage 2, specifically comprise following fine division step: inner flow passage 2 is arranged on fixture block 3 by c1., this fixture block 3 is preferably moulding, can certainly be other materials such as metalwork, mounting means can be the modes such as screw thread is fixed, interference fit, plastics cold welding; C2. the fixture block 3 this being provided with inner flow passage 2 is placed in plastic casing 1 and is fixed, and fixed form is cold welding.
D. fill the region outside inner flow passage in plastic casing, filler is cement or resin or steel sand, also can be the mixture of above two or three.
E. glossiness process is carried out to plastic casing.Plastic casing, without polishing, directly can carry out electroplating processes, and the plastic casing surface handled well has metallic luster, is as good as with metal.
Protection scope of the present invention includes but not limited to above embodiment, and protection scope of the present invention is as the criterion with claims, and any replacement that those skilled in the art will find apparent that, distortion, improvement made this technology all falls into protection scope of the present invention.
