Abstract
The utility model relates to a mold core structure replacing polyurethane. The mold core structure is characterized in that: the mold core structure comprises a plurality of imitative blocks made of rigid material, which are matched with the cavities of products, the imitative blocks are sequentially arranged at intervals, and moreover, the neighboring imitative blocks are connected together by a connector made of flexible material. Compared with the prior art, since the utility model adopts the imitative blocks made of rigid material and sequentially arranged at intervals and utilizes the flexible connectors to ensure that the mold core structure can be bent and automatically restored, while having the function of polyurethane, the mold core structure cannot be easily abraded and still can keep the shape and the function after being repetitively inserted and pulled out, and therefore the service life of the mold core structure can be remarkably prolonged; when being applied to bent products, the mold core structure does not need to be frequently replaced, consequently, the continuity of production is guaranteed, the production efficiency and the product quality are high, the production cost is low, meanwhile, the stability of the mold is enhanced as well, and product abnormities caused by the mold are reduced.
Description
Technical field
The utility model relates to a kind of core structure that substitutes excellent power glue, specifically refers to a kind of core structure that is applied in the processing rate of curving than the miscellaneous goods occasion.
Background technology
Polyurethane (English name: Polyurethane, be called for short PU, be commonly called as excellent power glue) be a kind of elastomer between plastics and rubber, it has abrasion performance, resistance to chemical attack, high resiliency, tear-resistant, superperformance such as radiation hardness and damping, buffering, the hardness range that has broad simultaneously, these unique combination properties are that common plastics and rubber is not available, thereby be widely used in metallurgy, the mine, oil, automobile, building materials, physical culture, heavy-duty machinery, the damping backing plate of large-scale pressing equipment, cushion block, spring, and do various metallic plates, pipe etc. dash the material mould, especially be used as die springs, play buffering or cushioning effect.
When bending die is produced bent products, above-mentioned excellent power glue is applied in the semi-finished product of bent products, promptly has the cavity that matches with excellent power glue shape in semi-finished product inside, after excellent power glue is inserted into this semi-finished product cavity for the treatment of bending, under the effect of bending die, just can guarantee that the section of semi-finished product when bending is indeformable.When the semi-finished product bending finish be shaped to product after, excellent power glue splits out in the product cavity, continues to recycle after treating.
But in the bent products forming process, find, owing to the frequent insertion of excellent power glue, extract, can accelerate self wearing and tearing of above-mentioned excellent power glue.General excellent power glue uses just to be needed about one and a half months to change once, then needs after the replacing to spend about one hour to adjust bending die, and the adjusted initial stage has several bad products and occurs.The frequent replacing of excellent power glue simultaneously also can cause the raising of production cost, and has the continuity that influence is produced, and increases product unstability and the defective that reduces production efficiency.
The utility model content
Technical problem to be solved in the utility model is at above-mentioned prior art present situation, and a kind of long service life is provided, and can guarantee to produce the successional core structure that substitutes excellent power glue.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this substitutes the core structure of excellent power glue, it is characterized in that: comprise the profiling piece that several and the product cavity made by rigid material are complementary, each profiling piece is spaced successively, and the connector that the profiling piece between adjacent is made by a flexible material fuses mutually.
Gap between the above-mentioned adjacent profiling piece is good with 0.8mm～3mm, to satisfy the bending machining needs of micro-bent products.
Be connected by securing member between the plates that described connector can be made for the mild steel material, these plates and corresponding profiling piece.These plates can be a plurality of, and the two ends of each plates are connected on the adjacent profiling piece.But for convenience easy to process and assembling, described plates preferably are processed into long and narrow plates, and these long and narrow plates are through each profiling piece.
Compared with prior art, because the utility model adopts the spaced successively profiling piece of rigidity material, utilize soft connector can guarantee that the utility model can crookedly also can automatically reset simultaneously, thereby the utility model is when satisfying excellent power glue function, repeatedly inserting, after the dial-out, also not easy to wear, still can guarantee its shape and function of use, so the utility model can increase the service life significantly, when it is applied on the bent products, just need not frequent replacing, so both guaranteed the continuity of producing, and made the qualification rate height of production efficiency and product, production cost is low, improve simultaneously the stability of mould again, reduced the product anomaly that causes because of the reason of mould own.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is plugged in the end face structure schematic diagram that the outer water of automobile is cut for the utility model embodiment.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the core structure that should substitute excellent power glue is applied to produce the outer water of automobile and cuts 4, it comprises several profiling pieces 1 of being made by ferrous material, the outer water of each profiling piece 1 upper end shape and automobile is cut 4 inner chamber and is matched, and each profiling piece space is successively arranged, and the gap L between the adjacent profiling piece 1 can be 0.8mm～3mm, can think 0.8mm, or 2mm, or 3mm, the connector of making by a mild steel between each profiling piece fuses mutually.In the present embodiment, connector is made long and narrow plates 2, is connected by screw 3 between these long and narrow plates and the corresponding profiling piece.
Above-mentioned profiling block length (along long and narrow plates length direction) can require design according to the curvature of bent product, in the present embodiment, can design between 50mm～60mm.
When water is cut outside producing automobile, above-mentioned core structure is inserted into outer water cuts in half-finished cavity, under the effect of bending die, the semi-finished product brake forming becomes the outer water of required form to cut.After the die sinking, above-mentioned core structure extracted in Wai Shui cut cavity.After being repeatedly used, still can keep original shape and performance like this.
Claims (4)
