Abstract
The invention relates to an injection molding threaded hole forming process of high-temperature-resistant material. A nylon high-temperature-resistant material containing 50% glass fiber is in injection molding through an injection molding machine, and the threaded hole forming is achieved by post-processing the thread through a forming part, a product is provided with high hole threads and low hole threads, and the process comprises the following steps in sequence: (1) drying material, and placing on the die, wherein the die is provided with a central injection molding hole and at least two heating channels and is provided with a heat insulating board to keep the temperature of the die; (2) debugging to pass quality testing, conducting injection molding to form an injection molding piece; (3) performing thread post-processing on the injection molding piece, performing threaded hole forming on the product, wherein the threaded hole forming is formed by tapping after drilling. The process provided by the invention has the advantages that a plug screw is hard to loosen after the plug screw corresponding to the processed threaded hole is screwed up, and the thread is hard to damage.
Description
Technical field
The present invention relates to a kind of injection moulding screwed hole moulding process of exotic material.
Background technology
Injection molding process is the very important type of skill in plastic products processing, and the working of plastics processing of most industries all needs injection molding process to complete.Related industry and field are very wide, can use as industries such as food, electronic apparatus, instrument, daily, chemical industry, agricultural, transportations the plastics original paper that injection molding process is made.
Injection mo(u)lding is one of main method of plastic product forming, and nearly all thermoplastic, multiple thermosetting plastics and rubber is available this method moulding all.Injection-molded item comprises the little even various instrument pinions of several milligrams of several grams that arrive, microelectronic element, and medical little apparatuses etc. arrive greatly television set, the washing machine shell of several kilograms, automotive plastic spare etc.
Contain 50% glass fibre (Grivory is trade name and the trade mark of a kind of high temperature resistant nylon of Switzerland EMS company) due to GRIVORY HTV-5H1 BLACK, belong to thermostability high, penetrate the level material.Yet the screwed hole of injecting products of my department is in that sealing requirements is very high, double thread torsion requires very high.General injection molding process is difficult to reach requirement.
Summary of the invention
The object of the invention is to: provide a kind of injection moulding screwed hole moulding process of exotic material, with the sealing requirements that satisfies the double thread hole and the torsion requirement of double thread.
The object of the invention is achieved through the following technical solutions: a kind of injection moulding screwed hole moulding process of exotic material is to contain the nylon exotic material of 50% glass fibre by injection machine, injection mo(u)lding; By profiled member is carried out rear machining screw, reach the screwed hole moulding again.
The present invention presses following technological forming: first the selection of material GRIVORY HTV-5H1 BLACK injection mo(u)lding, and product is provided with high hole screw thread and low hole screw thread, and technique comprises:
1) baking material, patrix, wherein, mould has center injecting hole and at least two heat tunnels, and thermal insulation board is set mould is incubated;
2) die trial goes out moulding to quality inspection (QC) by entering injection mo(u)lding;
3) moulding is carried out processing after screw thread, the moulding of product screw, described screw moulding are by the rear tapping moulding screw of holing.
Superiority of the present invention is: the plug screw that the screw of processing is corresponding is tightened rear plug screw and is difficult for not easy damaged of loosening, screw thread.

The specific embodiment
As attached illustrated in figures 1 and 2, the product screw moulding flow process that the present invention relates to: in the steps below sequentially:
1) first the selection of material GRIVORY HTV-5H1 BLACK injection mo(u)lding has high hole screw 11 and low hole screw 12 in product 1, technique comprises:
2) baking material: will dry by the fire good material (GRIVORY HTV-5H1 BLACK) injection mo(u)lding on injection machine, patrix, wherein, mould has center injecting hole and at least two heat tunnels, and thermal insulation board is set makes the mould insulation, need in injection moulding process to heat to mould, temperature range is: 120 ~ 145 ° of C;
3) die trial goes out moulding to quality inspection (QC) by entering injection mo(u)lding;
4) with the first product of injection formed, detect and moulding is carried out processing after screw thread, the moulding of product screw, low hole screw 12 processing: be plug screw processing front schematic diagram in low hole in Fig. 2 as Fig. 3, Fig. 4 is that in Fig. 2, low hole plug screw is processed shown in rear schematic diagram, and plug screw 121 positions, low hole as shown in the figure; High hole screw 11 processing: be that in Fig. 2, high hole plug screw front the schematic diagram of processing and Fig. 6 are high hole plug screw processing schematic diagram afterwards in Fig. 2 as Fig. 5, plug screw 111 positions, high hole as shown in the figure; Described screw moulding is by the rear tapping moulding screw of holing, with after the product trial assembly that processes, survey torsion and will reach requirement.
The plug screw that the screw of processing is corresponding is tightened rear plug screw and is difficult for not easy damaged of loosening, screw thread.
