Abstract
The porous exhaust plug made of Cu, Al, Fe or other metal and alloy or non-metal has pores of 0.001-0.1 mm size. The porous exhaust plug makes it possible to provide excellent ventilation while preventing rubber or plastic material from spilling during sulfurization and extrusion. As one ideal ventilation device for rubber and plastic mold, the porous exhaust plug is cheap and accurate and can raise quality of rubber and plastic products.
Description
The invention relates to mould, particularly porous exhaust plug for rubber and plastic mold.
The pore cover is a kind of small parts on the rubber and plastic mold, be mainly used in rubber, plastics are discharged the air between product surface and mould in sulfuration or extrusion, make goods bent angle etc. locate to be full of rubber and plastic, complete and attractive in appearance as the surface of tyre decorative pattern, the slyness of frosting and bright and clean, but traditional tire pore cover, it is shaped as the column type of band endoporus, outside dimension is Φ 2-Φ 4mm, internal diameter is Φ 0.6-Φ 1.2mm, decides according to the different needs of riding tire and load-carrying tire, and material is generally stainless steel, as ICr18Mi9Ti etc., though can exhaust, influenced the outward appearance of tire, in sulfidation, when pore is enclosed within exhaust, sizing material also thereupon overflow enter in its endoporus, form adhesive tape, during the demoulding, again along with tire is taken out of, stay on the tyre surface, make tyre surface have many diameter of phi 0.6-Φ 1.2mm, long 8-15mm adhesive tape, there is following defective: 1. seem very not attractive in appearance, influence precision; 2. stop up mould easily; 3. waste the goods raw material; 4. the tire of run-of-the-mill requirement does not need to dispose, but the tire that high-quality requires then needs after-treatment, and adhesive tape is removed, and effect is undesirable, and low precision is influential to presentation quality, makes troubles to manufacturer, and noise is arranged when particularly running at high speed, and resistance is big; 5. maintenance of clean-up mould difficulty; And developed country utilizes the exhaust of segmented mold junction gap, its complex structure, and the Mould Machining difficulty, the precision height, cost is big, is difficult to satisfy instructions for use.
The purpose of the invention is at above deficiency, and a kind of easy porous exhaust plug is provided, and profit is wanted the exhaust of micropore gap, and don't make the residual any rubber and plastic adhesive tape of product surface, greatly improved the goods precision, and simple in structure, cost is low, can satisfy rubber, mould of plastics instructions for use.
Porous exhaust plug for rubber and plastic mold, comprise pore cover 1, micropore 2, it is characterized in that being outside equipped with some micropores 2 in the pore cover 1, its micropore 2 is to be made of the gap that metal or nonmetal pore overlap 1 material, be because pore overlaps 1 material, as copper, aluminium, metal such as iron and alloy or the above particle of nonmetal 80 orders adopt sintering process processing in manufacture process, the micropore of the 0.001-0.1mm that on section, forms, have good venting quality and anti-rubber and plastic permeability, can exhaust in sulfidation, and don't overflow the rubber and plastic adhesive tape, withstand voltage 30 atmospheric pressure, high temperature resistant 200 ℃, can satisfy its quality of item requirement.
The invention is the significant improvement in rubber, the mould of plastics, particularly tire-mold has had desirable, cheap, high-precision exhaust apparatus, improved the goods precision, having reduced the mould accuracy of manufacture requires and cost, the surface does not need secondary operations to handle, save a large amount of human and material resources, avoided mould to stop up and wastage of material, simple in structure, make easily, easy to use, the easy-maintaining cleaning has guaranteed product quality, for manufacturer has brought favorable economic benefit and social benefit, be the revolution of die venting device, be suitable for penetration and promotion.
The invention accompanying drawing 1 is a structural representation, and Fig. 2 is the A-A cross-section cutaway view, wherein pore cover 1, micropore 2, mould 3, goods 4.
Embodiment:
The I type, 185/70R14 tire-mold venting plug, diameter of phi 4mm, long 5mm is cylindric, and material is 80 order steel alloys, the sintering manufacturing, micro-pore diameter Φ 0.02mm, the undulations tire, 2000 of steam vents, the surface of tyre precision reaches more than the V level.
The II type, large-scale plastic bath tub die venting plug, section 3 * 3mm
2, long 8mm, rectangle, material is 90 order alloy aluminum, sintering manufacturing, micro-pore diameter Φ 0.08mm, 200 of steam vents, bathtub surface roughness Ra 0.08.
The III type, large-sized plastic rubber casing die venting plug diameter of phi 6mm, long 10mm is cylindric, and material is that 100 orders pottery is made micro-pore diameter Φ 0.1mm, 100 of steam vents, casing surface roughness Ra 0.08.
The IV type, small-sized rubber parts die venting plug, diameter of phi 4mm, long 5mm, cylindric, material is 90 order activated carbon, sintering manufacturing, micro-pore diameter 0.05mm, surface roughness Ra 0.05.
Claims (5)
