Abstract

The utility model relates to a rubber cylinder demoulding device which mainly comprises a pistil mould, an upper end block, a sealing clamping ring, a balance weight, an annular seat water pump, etc., wherein the pistil mould which is formed with a rubber cylinder is arranged on an annular seat, the sealing clamping ring is clamped on the rubber cylinder, and then water with certain pressure is pressed into a cavity by the water pump, and the cavity is formed by the pistil mound and the upper end block. With the augmentation of the pressure of water, the rubber cylinder is gradually separated from the pistil mound. The utility model has the advantages of simple structure and simple and convenient operation, and moreover, the utility model can realize the demoulding of work pieces with various sizes and has the advantages of economy and high precision to the work pieces.

Description

The rubber tube stripper apparatus

The utility model relates to a kind of rubber packing element stripper apparatus.

The form of present domestic rubber tube mould generally is two kinds, wherein a kind of form is powerful the separation, as shown in Figure 1, utilize the external force p1 and the p2 of positive and negative two positive directions, use puller system to separate by force, use rubber tube 31 to separate by force with mould stamen 11, this kind mode is confined to packing element than growing and must having certain thickness, as 1500 * 25mm, if cross thin just can not be oversize, destroyed rubber tube when being forced to separate as 300 * 4mm and termination, waste is big, and needing stronger mechanical external force, must there be fineness preferably on stamen mould surface, for example will reach 1.6.So can not pull out the round packing element that the reticulate pattern shape is arranged in the packing element.Another kind of mode is to adopt manufacturing process, and the stamen mould is dwindled to reach the purpose of packing element and mold separation, and this kind mode is that the Mould Machining manufacture difficulty is big, the expense height, and after the rubber tube demoulding overlap is arranged.

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, easy to operate rubber tube stripper apparatus, it utilize to inject water under high pressure, makes rubber tube utilize water to have the characteristics of lubricity preferably and characteristic that rubber tube expands to finish the demoulding to rubber under the pressure effect of water.

The purpose of this utility model realizes by following manner.Rubber tube stripper apparatus of the present utility model, it comprises the stamen mould, the upper end is stifled, seal snap ring, counterweight, ring seat, water pump and water pipe, wherein the stamen mould is closed tubular spare, the end of tube is design like this, one end is provided with an end cover along the edge of tube, there is a male member this end cap outside, the other end has a spacing place to be provided with a seal cover near the edge in tube, it is to make stamen mould and ring seat phase configuration together by recess that its boss is placed on ring seat that the stamen mould has an end of end cap male member, it is stifled that the other end of stamen mould is provided with a upper end, stifled convex edge, this upper end just in time snaps onto in the tubular stamen mould, and the stifled inner surface in upper end maintains certain distance with the interior seal cover of tube, outer and stamen mould external diameter that the upper end is blocked up are unidimensional, the upper end is blocked up a limbers, this limbers is communicated to the chamber that forms between the stifled and end cap in upper end, and this limbers is communicated in water pump by tube connector, and the outside that is formed with rubber tube at the stamen mould is provided with seal snap ring, the sealing snap ring is to be stuck in to be positioned at stifled position, upper end, and stifled outside, upper end is provided with a counterweight.

Operation principle of the present utility model be with stamen mould kiss-coating again when needing the demoulding after the required operation, the stamen mould is placed on the ring seat, promptly boss is placed in the ring seat recess, installs the termination seal snap ring subsequently, and configures counterweight more stifled than the upper end and that snap ring is slightly heavy; Be communicated with the water pump water pipe subsequently, water pump is gone into hydraulic pressure, and its pressure is preferably ascending, and general hydraulic pressure is 2MPa-50MPa, increase along with hydraulic pressure, rubber tube expands, and strain takes place under external force for it, and begins to become flexible, when hydraulic pressure is enough big, the stamen mould is still motionless on ring seat, and rubber tube and upper end are blocked up in the effect down that reaches snap ring one cause counterweight and moved, and its rubber tube breaks away from stamen mould the most at last.

The utility model is simple in structure, and is easy to use, even there are floral designs such as reticulate pattern all can once to finish in the rubber tube, this device is not subjected to size, and the thin and thick size limits, and is difficult for causing waste, the machining accuracy height.

Further describe structure of the present utility model below in conjunction with accompanying drawing, wherein

Fig. 1 is the schematic diagram of the prior art rubber tube demoulding;

Fig. 2 is the schematic diagram of rubber tube stripper apparatus of the present utility model.

Now referring to Fig. 2, it comprises stamen mould 1, upper end stifled 2, seal snap ring 4, counterweight 5, ring seat 6, wherein stamen mould 1 is closed tubular spare, one end of tube is provided with an end cover along the edge of tube, it can be an one with tube, there is a male member (as shown in the figure) this end cap outside, and the other end has a distance to be provided with a seal cover near the edge in tube, and the seal cover outside is provided with a upper end stifled 2 in the edge of tube, stifled convex edge, this upper end just in time snaps onto in the tubular stamen mould 1, and maintain certain distance with capping, the outer and the stamen mould 1 of upper end stifled 2 are unidimensional, on the upper end stifled 2 limbers (as shown) are arranged, this through hole is communicated to the chamber that forms between upper end stifled 2 and the end cap, this limbers is communicated in water pump (not shown) by managing 7, and the outside that is formed with rubber tube 3 at stamen mould 1 is provided with seal snap ring 4, and sealing snap ring 4 is to be stuck in the position that is positioned at upper end stifled 2.Upper end stifled 2 is provided with counterweight 5.
