Abstract
The invention discloses a thin-walled workpiece mould. The thin-walled workpiece mould comprises a front mould and a rear mould, wherein the center part of the front mould is provided with a pouring gate, the front mould and the rear mould are internally and respectively provided with a plurality of front moulding chambers and rear moulding chambers, the front moulding chambers and the rear moulding chambers are provided with inner gate runners communicated with the pouring gate in the center of the front mould, and inner gate runners are connected with the front moulding chambers and the rear moulding chambers through horn gates; and the inner gate runners of the front mould are provided with a plurality of pouring points. The thin-walled workpiece mould provided by the invention has the advantages that the structure is simple, the horn gates are used for pouring, and a product after casting moulding does not need to be trimmed, so that onet-time forming of the product can be achieved, and the production efficiency is improved.
Description
Technical field
The present invention relates to mould applications, relate in particular to a kind of thin-wall part mould.
Background technology
Mould is the instrument of formed article, decides according to the profile of product, and mould structure is also a lot.Because mould can be realized the product mass production, therefore, it is widely used in various fields.General mould is made of front mould and rear mold or upper die and lower die mostly, during use, front and back mould or upper and lower mould is installed at together, then injects melting charge, extruding cooling forming, finally demould.General injecting products periphery after the demoulding can produce burr, and therefore, the later stage need to be carried out deburring to injecting products, and working (machining) efficiency is reduced; Therefore and for the product of processing thin-walled, due to its thin thickness, easily damage product when the later stage deburring.
Summary of the invention
Technical problem to be solved by this invention is that a kind of thin-wall part mould that makes the time processing moulding of thin-wall part mould and need not deburring is provided.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of thin-wall part mould, comprise front mould and rear mold, described front mould centre is provided with cast gate, be respectively arranged with some front die cavitys and rear die cavity in front mould and rear mold, be provided with the ingate that is communicated with described front mould trumpet assembly on described front die cavity and rear die cavity, all be connected by cow glue powder between described ingate and front die cavity and rear die cavity.
Even in order to guarantee to pour into a mould, further, be provided with some watering a little on described front mould ingate.
Compared with prior art, usefulness of the present invention is: this thin-wall part mould structure is simple, pours into a mould by cow glue powder, makes the product after moulding by casting need not deburring, thereby realizes the time processing moulding of product, enhances productivity.
Description of drawings:
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is a kind of thin-wall part mould of the present invention front mould structural representation;
Fig. 2 is a kind of thin-wall part mould of the present invention rear mold structural representation.
In figure: 1, front mould; 11, cast gate; 12, water a little; 2, rear mold; 3, ingate; 31, cow glue powder; 4, front die cavity; 5, rear die cavity.
The specific embodiment:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
Fig. 1, a kind of thin-wall part mould shown in Figure 2, comprise front mould 1 and rear mold 2, described front mould 1 centre is provided with cast gate 11, be respectively arranged with some front die cavitys 4 and rear die cavity 5 in front mould 1 and rear mold 2, be provided with the ingate 3 that is communicated with described front mould 1 trumpet assembly 11 on described front die cavity 4 and rear die cavity 5, all be connected by cow glue powder 31 between described ingate 3 and front die cavity 4 and rear die cavity 5, in order to guarantee cast evenly, be provided with on described front mould 1 ingate 3 and somely water a little 12.
During use, front mould 1 and rear mold 2 are combined, then by cast gate 11 and water a little 12 in the mould injection injection moulding liquid, potting syrup is by ingate 3 water conservancy diversion, then inject in front die cavity 4 and rear die cavity 5 by the cow glue powder 31 that is communicated with ingate 3 and the rear die cavity 5 of front die cavity 4, after cooling, separate front mould 1 and rear mold 2, then by thimble, injecting products is ejected and get final product.
This thin-wall part mould structure is simple, pours into a mould by cow glue powder 31, makes the product after moulding by casting need not deburring, thereby realizes the time processing moulding of product, enhances productivity.
It is emphasized that: above is only preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
