Abstract

The utility model discloses a core mold structure, in particular to a cast bus inter-phase core mold structure. The structure comprises two end plates, the shapes of the two end plates adapt to those of end contours of elongated inter-phase inner holes in a cast bus body, a detachable left side plate and a detachable right side plate are arranged between the connecting ends of the left and right sides of the two end plates respectively, and at least one detachable middle supporting piece is arranged in the middle of the left side plate and the right side plate. By adopting the structure, the stripping area of a single core mold is reduced, stripping is convenient, core molds with multiple sizes can be combined by adjusting the sizes of the left side plate and the right side plate, the investment cost is reduced, storage is convenient, and inter-phase interval casting of cast buses and stripping of the inter-phase core mold can be met; due to elasticity and toughness of engineering plastics of polyvinyl chloride (PVC), acrylonitrile butadiene styrene (ABS) and the like, stripping is easy and convenient, the mold is removed without damage and can be reused, the loss of the mold is reduced, and the cost is reduced.

Description

The alternate core mode structure of cast bus

Technical field

The utility model relates to a kind of core mode structure, specifically the alternate core mode structure of a kind of cast bus.

Background technology

The alternate mould used of cast bus adopts integral form more, after cast because of the extrusion die that expands with heat and contract with cold of material, make mould compression, therefore very difficult when the demoulding, even will destroy mould could take out, so the mould of integral form often just must abandon after using once, can't reuse; Pour into a mould the alternate sizes that needs of bus simultaneously and make alternate layout more scientific, reasonable, attractive in appearance, the integral form mould need to be made sizes just can reach above-mentioned requirements, increases cost, and mould is of a great variety also makes troubles to mold storing.

Summary of the invention

The utility model is intended to address the above problem, and provides a kind of cast bus alternate core mode structure, has solved the defect that the unitary mould form can't be reused and can't meet the plurality of specifications demand, and its technical scheme adopted is as follows:

The alternate core mode structure of a kind of cast bus, comprise two blocks of end sheet materials, the profile of two blocks of end sheet materials adapts with the end profile shape of building the alternate endoporus of the long groove shape arranged on bus bulk, be respectively arranged with dismountable left plate and right plate between the link of the sheet material left and right sides, two ends, the middle part of left plate and right plate at least is provided with a dismountable intermediate support.

Described left plate and right plate are arranged to respectively the polylith matched with intermediate support, the cross sectional shape of every left plate and right plate is the bathtub construction with in-flanges, and described end sheet material and intermediate support are provided with and the peg graft draw-in groove of cooperation of described in-flanges simultaneously.

The material of described end sheet material, intermediate support and left plate and right plate is PVC, ABS engineering plastics.

After adopting above-mentioned structure, because the core mould of traditional integral formula is set to dismountable some parts, form a hollow assembly by intermediate support between each several part, reduced single piece type core demoulding area, be convenient in demoulding, not only can be by adjusting the size of left plate and right plate, be combined into the core mould of plurality of specifications, reduce input cost, the convenient storage, can also meet the different alternate interval cast of cast bus and be convenient to the form removal of alternate core mould, adopt PVC, the elasticity of the engineering plastics such as ABS and toughness, make the demoulding become light, convenient, do not need to destroy mould and remove, reusable, reduced the mould loss, saved cost.

The accompanying drawing explanation

The perspective view that Fig. 1 is the alternate core mode structure of the utility model cast bus;

The mounting structure schematic diagram that Fig. 2 is the alternate core mode structure of the utility model cast bus.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the alternate core mode structure of cast bus of the present utility model is described in further detail.

Embodiment mono-:

As shown in the figure, the alternate core mode structure of cast bus of the present utility model, comprise two blocks of end sheet materials 2, the profile of two blocks of end sheet materials 2 adapts with the end profile shape of the alternate endoporus 3 of building the long groove shape arranged on bus bulk 1, be respectively arranged with dismountable left plate 5 and right plate 6 between the link of two end sheet material 2 left and right sides, the middle part of left plate 5 and right plate 6 is provided with a dismountable intermediate support 4, and by intermediate support 4 support reinforcing Strength retention external shape, left plate 5 and right plate 6 are arranged to respectively two, the cross sectional shape of every left plate and right plate is the bathtub construction with in-flanges, end sheet material 2 and intermediate support 4 are provided with the draw-in groove matched with bathtub construction simultaneously, by the bathtub construction with in-flanges and the draw-in groove arranged, can be by left plate and right plate and intermediate support 4 installing/dismountings, can form a hollow barrel type core by above-mentioned arranging, end sheet material 2 and left plate 5 and right plate 6 composing type core profiles, intermediate support 4 is in inner its supporting role of core mould, to not contact material, various piece is installed, convenient disassembly is quick, sound construction, during use, adopt application specific architecture to be fixed on casting mold.

Embodiment bis-:

On the basis of embodiment mono-, further intermediate support 4 can be arranged to polylith, left plate 5 and right plate 6 also are arranged to respectively the polylith matched with intermediate support 4, when middle support member is arranged to the n piece, left plate 5 and right plate 6 are arranged to respectively the n+1 piece, can utilize thus left plate 5 and right plate 6 that intermediate support and two end sheet materials 2 combinations are formed to an integral body.

The material that simultaneously it should be noted that end sheet material 2, intermediate support 4 and left plate 5 and right plate 6 is PVC, ABS material, also can, for the engineering plastics of other form, in the utility model, it not done and enumerate.

During use, be poured can the demoulding time, because intermediate support 4 does not contact material, can easily it be extracted, again because of the core mold materials be adopt have elasticity and toughness with PVC, the engineering plastics such as ABS are made, therefore can make by the sidewall of left plate 5 and right plate 6 and two blocks of end sheet materials 2 left plate 5 and right plate 6 and two blocks of end sheet materials 2 break away from from alternate 6 one by one, be beneficial to take out the core mould, and the core mould need not be destroyed, whole core mould is resolved into to some parts, the complementary interference during demoulding, reduce individual module demoulding area, be beneficial to the demoulding, and the core mould is reusable, and by using left plate 5 and right plate 6 and two blocks of end sheet materials 2 of different size, the core mould of one-tenth different length size capable of being combined.

Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
