Abstract
The invention discloses a core die of a rubber product die. The core die comprises an upper core die and a lower core die, wherein holes are formed in the upper core die and the lower core die; the lower part of the upper core die is provided with a stepped boss or a concave groove; the upper part of the lower core die is correspondingly provided with a concave groove or a stepped boss; the concave groove or the stepped boss of the lower core die is sleeved on the stepped boss or the concave groove of the upper core die; and the joint part of the lower core die and the upper core die is communicated with the holes in the centers of the upper core die and the lower core die. In order to solve the bubble problem, the core die does not take general technical measures, but adopts a technical scheme for eliminating or reducing bubble-induced defective products by a splitting technical principle according to the core die structure, wherein a conventionally designed solid core die is decomposed into an exhaust core die combined by parts with cavities, so that gas can smoothly escape during production, and bad residues and defects are absent on the surface of rubber products in contact with the exhaust core die. The core die has the advantages of being simple and compact in structure, convenient for integration and standard design and manufacturing and beneficial to reduction of an installation space.
Description
Technical field
The present invention relates to a kind of rubber mould core.
Background technology
Rubber produces mass defects such as bubble owing to factors such as mould, temperature, pressure, prescription design may cause the surface of rubber or inside in process of production.Bubble is a kind of common bad phenomenon, and is light then influence the presentation quality of product, heavy then cause scrapping of product, and lost labor and material increase manufacturing expense.The reason of bringing out bubble is a lot, and as gas remaining in the sizing material, can expand under suitable conditions such as temperature produces bubble; The moisture that sizing material or die surface are stained with also may generate bubble under the certain condition; Mould structure design is unreasonable when causing sulfuration, and gas can't be discharged smoothly, also may impel the generation of bubble.Above-mentioned three kinds of situations in actual production, may act on also possibility comprehensive function separately, facilitate the formation of bubble.
A kind of rubber as shown in Figure 1, this product is after sulfuration finishes, and often can find has bubble on the surface within it.Bubble is not of uniform size, irregular following on opportunity occur.Big person such as quail egg, the little seemingly grain of rice.Big person influences product size to be caused and scraps, and little need are eliminated with special tool(s) is careful.In the production, adopt the routine techniques measure as improving prescription, adjusting exhaust number of times, pressure, temperature etc. repeatedly, still can't reduce bubble quantity and bubble and probability.Bubble becomes the key factor of this product ordinary production of restriction.From the structure of this product and the position analysis of bubble appearance, find that the original mould core is an overall structure, its internal gas does not communicate with the outside, and gas is forced to stay goods inside after pressurizeing when causing sulfuration, forms bubble.
Summary of the invention
The object of the present invention is to provide a kind of in order to solve or to improve the rubber mould core that defective products rubber that bubble brings out produces.
Technical program of the present invention lies in: comprise core, following core, porose in last core and the following core; Step boss or Baltimore groove are arranged at last core bottom, corresponding Baltimore groove or the step boss of being provided with it in the top of following core, and the Baltimore groove of following core or step boss are set on the step boss or Baltimore groove of core; Following core is connected with the hole at last core and following core center with the joint portion of last core.
Described hole of going up in core and the following core is through hole.
Described hole of going up in the core is half through hole, and the hole in the following core is through hole.
Described upward core is two sections, and pars infrasegmentalis has step boss or Baltimore groove on the last core; Corresponding Baltimore groove or the step boss of being provided with it in the top of last core hypomere, pars infrasegmentalis has step boss or the Baltimore groove with the corresponding setting of following core under the last core; The Baltimore groove of last core hypomere or step boss are set on the step boss or Baltimore groove of core epimere; The Baltimore groove of pars infrasegmentalis or step boss are set in down on the step boss or Baltimore groove of core epimere under the last core.
Described core down is two sections, and step boss or the Baltimore groove with the corresponding setting of last core arranged at following core epimere top; Pars infrasegmentalis has step boss or the Baltimore groove with the corresponding setting in following core hypomere top on the following core; Corresponding Baltimore groove or the step boss of being provided with pars infrasegmentalis on the following core arranged at the top of following core hypomere.
The present invention does not adopt common technical measures when solving air bubble problem, but at the core structure, adopts the Split Method know-why, with the solid core of prior art, resolves into the exhaust core that some parts that cavity arranged are combined into.Have an ease gas face on the core of the present invention at least, reaching when producing gas can overflow smoothly, does not have the purpose of bad residual and defective with the contacted rubber article of exhaust core.The present invention is simple for structure, is convenient to integrated, standardized designs manufacturing.Compact conformation of the present invention is conducive to reduce installing space.
