Description
Technical field
The present invention relates to a kind of mould structure, particularly relate to a kind of Liquid silicone rubber injection mould.
Background technology
Liquid silicone rubber injection mould is the one of thermosetting plastics mould, can with liquid-state silicon gel as shaping raw material, silica gel injection machine is sent into by special mixing system, and inject in the liquid-state silicon gel mould of heating by silica gel injection machine in the bet of certain pressure x velocity, to obtain silica gel product, can fully-automatic production be realized, there is the advantage that efficiency is high.
At present, silica gel part many employings Liquid silicone rubber injection mould of falling is resisted to make for mobile phone and electronic product etc. for water proof and dust proof, traditional Liquid silicone rubber injection mould silica gel ubiquity die joint selects irrational shortcoming, thus causes Mould Machining difficulty large, is vented bad; Finally cause product starved, the bad problems such as glue of overflowing.
Summary of the invention
The object of the present invention is to provide a kind of Liquid silicone rubber injection mould, it has the advantages that difficulty of processing low silica gel injection effect is good and converted products reliable in quality is stable, to solve Liquid silicone rubber injection mould Problems existing in prior art.
For reaching this object, the present invention by the following technical solutions:
A kind of Liquid silicone rubber injection mould, it comprises upper die and lower die, described counterdie offers the counterdie die cavity for placing working of plastics to be processed, wherein, described patrix is made up of the first patrix and second patrix two parts, the bottom of described first patrix offers model cavity, described second patrix is fixed in described upper model cavity, and the joint place of the sidewall of described second patrix and upper model cavity madial wall is as die joint, described first patrix is provided with sealing face along the periphery of described upper model cavity, during matched moulds, described sealing face and working of plastics are adjacent to the sealing area formed for injecting silica gel, described sealing area is provided with gum-injecting port and exhaust gear.
Especially, on described upper model cavity and the second patrix, correspondence offers several fixing holes, and the second patrix is fixed in upper model cavity through both fixing holes by hold-down screw.
Beneficial effect of the present invention is, compared with prior art the patrix of described Liquid silicone rubber injection mould adopts the first patrix and the second patrix two block structure, and using the joint place of the sidewall of the second patrix and upper model cavity madial wall as die joint, make a part of separate machined of silica gel part.Not only difficulty of processing reduces, and middle stitching portion can be vented, and is also convenient to the later stage repair a die and change mould, and silica gel injection effect is good, and product batch production steady quality is reliable.

1, patrix; 2, counterdie; 3, working of plastics to be processed; 4, counterdie die cavity; 5, the first patrix; 6, the second patrix; 7, upper model cavity; 8, fixing hole; 9, die joint; 10, sealing face; 11, silica gel.
Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Refer to shown in Fig. 1 to Fig. 3, in the present embodiment, a kind of Liquid silicone rubber injection mould comprises patrix 1 and counterdie 2, described counterdie 2 offers the counterdie die cavity 4 for placing working of plastics 3 to be processed, described patrix 1 is made up of the first patrix 5 and second patrix 6 two parts, the bottom of described first patrix 5 offers model cavity 7, on described upper model cavity 7 and the second patrix 6, correspondence offers several fixing holes 8, and the second patrix 6 is fixed in upper model cavity 7 through both fixing holes 8 by hold-down screw.The sidewall of described second patrix 6 and the joint place of upper model cavity 7 madial wall are as die joint 9, described first patrix 5 coordinate working of plastics 3 to be processed to be provided with sealing face, some roads 10 along the periphery of described upper model cavity 7, during matched moulds, described sealing face 10 is adjacent to working of plastics 3 to be processed the sealing area formed for injecting silica gel 11, described sealing area is provided with gum-injecting port and exhaust gear.
Please again consult shown in Fig. 3, during injection, working of plastics 3 to be processed is first placed in counterdie die cavity 4, and the first patrix 5 and the second patrix 6 are locked in together, and moves downward with counterdie 2 closed; Simultaneously the first patrix 5 designs sealing face 10 and is adjacent to working of plastics 3 to be processed.Working of plastics 3 to be processed and core rod form the sealing moulding region of silica gel 11, by one end glue mouth injecting glue, the full whole silica gel region of stream, in other end exhaust, by shaping for air discharge place silica gel region, then pressing through standby, silica gel 11 and working of plastics 3 to be processed is allowed to be bonded together, the Liquid silicone rubber injection mould produced like this there will not be excessive glue, the bad phenomenon such as starved, improves production yield.
During injection, using the joint place of the sidewall of the second patrix 6 and upper model cavity 7 madial wall as die joint 9, patrix 1 is divided into two pieces, make A place separate machined in figure, difficulty of processing reduces greatly, requires also to reduce to process equipment, middle stitching portion can be vented, and is also convenient to the later stage repair a die and change mould.
Above embodiment has just set forth general principle of the present invention and characteristic; the present invention does not limit by above-mentioned example; without departing from the spirit and scope of the present invention, the present invention also has various change and change, and these changes and change all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
