Abstract
The utility model discloses an impeller mold lined with fluoroplastics. The impeller mold comprises a bottom mold, a mold sleeve and an upper pressing mold which are arranged in sequence from bottom to top, wherein a middle pressing mold is coaxially arranged in an inner cavity of the mold sleeve; the upper pressing mold and the middle pressing mold are connected by bolts; flanges of the bottom mold and the mold sleeve are connected by bolts; a round-platform shape is adopted for the inner cavity of the upper pressing mold and is matched with the conical degree of the round-platform-shaped upper end of an impeller shaft to form axial limitation on the impeller shaft; the part on the bottom mold, which is positioned at the axis of the impeller shaft, is provided with a plugging piece seat connected on the bottom mold by screws; plugging pieces filled in an impeller channel are arranged between the bottom mold and the mold sleeve. The impeller mold disclosed by the utility model has the advantages that the problem of demolding of the impeller channel can be solved, the rate of qualified products is increased, and better separation of the mold is guaranteed, so that the service life of the mold is longer.
Description
Technical field:
The utility model relates to a kind of fluoroplastics lining impeller mold.
Background technology:
In prior art, the design of patch is overall piecemeal in mould, because runner is inner wide outer narrow form, completes and is easy to cause the distortion in impeller channel exit while carrying out the demoulding at impeller sintering.So, must ensure on the quality base of impeller, develop a kind of novel impeller mold and solve impeller and flow to the problem of the demoulding, improve the percentage of A-class goods of product.
Summary of the invention:
For overcoming the defect of prior art, the purpose of this utility model is to provide a kind of fluoroplastics lining impeller mold, can solve the problem of the impeller channel demoulding, improves the percentage of A-class goods of product, ensures that mould better separates, and makes the life-span of mould longer.
The utility model technical solution problem adopts following technical scheme:
A kind of fluoroplastics lining impeller mold, described mould comprises:
The bed die, die sleeve and the top die that set gradually from bottom to top are coaxially provided with middle pressing mold in the inner chamber of described die sleeve, between described top die and middle pressing mold, are bolted, and between described bed die and the flange of die sleeve, are bolted;
The inner chamber of described top die is made as truncated cone-shaped, mates with the tapering of the truncated cone-shaped upper end of impeller shaft the axial limiting forming impeller shaft;
The axis place that is positioned at impeller shaft on described bed die is provided with the patch seat being connected by screw on bed die, is provided with the patch being filled in impeller channel between described bed die and die sleeve.
Described patch is made up of multi-disc, multiple patches in impeller channel form annular, annular has center hole wall and the laminating of described patch seat of tapering, the afterbody of the each patch outside impeller channel is made as dovetail chip architecture, is provided with bolt hole for each patch is fixedly connected on to bed die on described dovetail sheet; Each patch is by the first patch with the second patch is compound forms on thickness direction, and the composite thickness of the first patch and the second patch is not more than the open height that of impeller channel.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
Mould of the present utility model is connected to form an entirety by top die and middle pressing mold with bolt, and die sleeve and each patch and bed die prevent overflowing of plastics with bolt integrated connection.The truncated cone-shaped inner chamber of top die has tapering and forms the axis of impeller shaft spacingly, and evenly and the position degree of product, at internal chamber wall tapering, place is axially arranged with some ventilating grooves along impeller shaft to the wall thickness that has ensured lining, the exhaust while being convenient to suppress.Multiple patches in this impeller channel, are designed, Design of Dies in the time of runner moulding has been considered the problem of the demoulding, so moulding place of runner has been designed to the first patch and the second patch is two-layer, and be processed into polylith patch according to the number of blade, in knockout course bed die take off to after take demoulding patch at the camber line that utilizes impeller channel.Because the runner thickness of impeller is inner wide outer narrow form, so considered the demoulding situation of patch to have designed the first patch and the second patch double-layer structure the two-layer open height that goes out that meets thickness and be no more than impeller channel when patch in design.Ensure that mould better separates, made the life-span of mould longer.
Brief description of the drawings:
Fig. 1 is overall diagram of the present utility model; Fig. 2 A, 2B are that the master of patch looks and top view; Fig. 3 is the schematic diagram of impeller after the demoulding.
Number in the figure: 1 bed die, 2 die sleeves, 3 top dies, pressing mold in 4,5 impeller shafts, 6 patch seats, 7 impeller channels, 8 dovetail sheets, 9 first patches, 10 second patches.
Below pass through detailed description of the invention, and the utility model is described in further detail by reference to the accompanying drawings.
Detailed description of the invention:
Embodiment: the mould of the present embodiment comprises:
The bed die 1, die sleeve 2 and the top die 3 that set gradually from bottom to top are coaxially provided with middle pressing mold 4 in the inner chamber of die sleeve 2, between top die 3 and middle pressing mold 4, are bolted, and between bed die 1 and the flange of die sleeve 2, are bolted; The inner chamber of top die 3 is made as truncated cone-shaped, mates with the tapering of the truncated cone-shaped upper end of impeller shaft 5 axial limiting forming impeller shaft.Evenly and the position degree of product, at internal chamber wall tapering, place is axially arranged with some ventilating grooves along impeller shaft to the wall thickness that has ensured lining, the exhaust while being convenient to suppress.
The axis place that is positioned at impeller shaft 5 on bed die 1 is provided with the patch seat 6 being connected by screw on bed die, between bed die 1 and die sleeve 2, is provided with the patch being filled in impeller channel 7.
Shown in Fig. 2 A, 2B, patch is made up of multi-disc, multiple patches in impeller channel 7 are spliced to form annular, structure, annular is along the circumferential direction divided into polylith, and this annular has center hole wall and the patch seat 6 of tapering fits, and the afterbody of the each patch outside impeller channel is made as dovetail chip architecture, is provided with bolt hole for each patch is fixedly connected on to bed die on dovetail sheet 8; Each patch is by the first patch 9 with second patch 10 is compound forms on thickness direction, and the composite thickness of the first patch and the second patch is not more than the open height that of impeller channel.Ensure that mould better separates, made the life-span of mould longer.
