Abstract
A kind of Core die of rubber product die, comprises core, lower core, porose in upper core and lower core; Step boss or Baltimore groove are arranged at upper core bottom, and the top of lower core is corresponding with it is provided with Baltimore groove or step boss, on the step boss that the Baltimore groove of lower core or step boss are set in core or Baltimore groove; Lower core is connected with the hole of upper core with lower core center with the joint portion of upper core.The present invention is when solving air bubble problem, do not adopt common technical measures, but for core mold structure, adopt Split Method know-why, propose a kind of technical scheme solving or improve the defective products that bubble brings out, by the solid core of conventional design, resolve into some exhaust cores having the part combination of cavity to become, when reaching production, gas can be overflowed smoothly, and the rubber article contacted with exhaust core is without bad residual and defect.Have simple for structure compact, be convenient to integrated, standardized designs manufacture, be conducive to the advantage reducing installing space.
Description
Technical field
The present invention relates to a kind of Core die of rubber product die.
Background technology
Rubber in process of production, because the factors such as mould, temperature, pressure, formula Design may cause the mass defect such as surface or producing bubbles inside of rubber.Bubble is a kind of common bad phenomenon, gently then affects the presentation quality of product, heavy then cause scrapping of product, lost labor and material, increases manufacturing expense.The reason of bringing out bubble is a lot, and as gas remaining in sizing material, can expand generation bubble under the conditions such as suitable temperature; The moisture that sizing material or die surface are stained with, also may generate bubble under certain condition; Mould structure design is unreasonable when causing sulfuration, and gas cannot be discharged smoothly, also may impel the generation of bubble.Above-mentioned three kinds of situations, in actual production, the also possibility comprehensive function of possible independent role, facilitates the formation of bubble.
A kind of rubber as shown in Figure 1, this product, after sulfuration terminates, often can find there is bubble on the surface within it.Air Bubble Size differs, and occurs irregularly following opportunity.Large person is as quail egg, little of the grain of rice.Large person affects product size to be caused and scraps, and little need special tool(s) carefulness is eliminated.In production, adopting routine techniques measure as improved formula, repeatedly adjustment exhaust number of times, pressure, temperature etc., still cannot reduce quantity and the probability of bubble.Bubble becomes the key factor that this product of restriction is normally produced.From the position analysis that structure and the bubble of this product occur, find that original mould core is an overall structure, its internal gas does not communicate with outside, causes gas after pressurizeing during sulfuration to be forced to stay goods inside, forms bubble.
Summary of the invention
The object of the present invention is to provide the Core die of rubber product die that a kind of defective products rubber brought out in order to solve or to improve bubble produces.
Technical program of the present invention lies in: comprise core, lower core, porose in upper core and lower core; Step boss or Baltimore groove are arranged at upper core bottom, and the top of lower core is corresponding with it is provided with Baltimore groove or step boss, on the step boss that the Baltimore groove of lower core or step boss are set in core or Baltimore groove; Lower core is connected with the hole of upper core with lower core center with the joint portion of upper core.
Hole in described upper core and lower core is through hole.
Hole in described upper core is half through hole, and the hole in lower core is through hole.
Described upper core is two sections, and on upper core, pars infrasegmentalis has step boss or Baltimore groove; The top of upper core hypomere is corresponding with it is provided with Baltimore groove or step boss, and under upper core, pars infrasegmentalis has the step boss that arrange corresponding to lower core or Baltimore groove; On the step boss that the Baltimore groove of upper core hypomere or step boss are set in core epimere or Baltimore groove; On the step boss that under upper core, the Baltimore groove of pars infrasegmentalis or step boss are set in lower core epimere or Baltimore groove.
Described lower core is two sections, and the step boss that arrange corresponding to upper core or Baltimore groove are arranged at lower core epimere top; On lower core, pars infrasegmentalis has the step boss that arrange corresponding to lower core lower section upper portion or Baltimore groove; The top of lower core hypomere has and correspondingly with pars infrasegmentalis on lower core is provided with Baltimore groove or step boss.
The present invention, when solving air bubble problem, does not adopt common technical measures, but for core mold structure, adopts Split Method know-why, by the solid core of prior art, resolve into some exhaust cores having the part combination of cavity to become.Core of the present invention has a gas face of escaping at least, when reaching production, gas can be overflowed smoothly, and the rubber article contacted with exhaust core is without the object of bad residual and defect.The present invention is simple for structure, is convenient to integrated, standardized designs manufacture.Compact conformation of the present invention, is conducive to reducing installing space.
