Abstract
The utility model relates to a front and rear frame mould for a top cover of a washing machine. The front and rear frame mould comprises an upper mould (1) and a lower mould (2) which are spliced to form a mould cavity (4), and the lower mould (2) is provided with a pouring channel (3) communicated with the mould cavity (4). Compared with the prior art, in the front and rear frame mould, the lower mould (2) is provided with the pouring channel (3) communicated with the mould cavity (4), and the lower mould is opposite to the back face of a front and rear frame, i.e. a pouring opening is arranged on the back face of the front and rear frame, so that the mark of the pouring opening on a pouring formed product by the mould is kept on the back face of the front and rear frame, and no treatment is needed for the pouring opening, thereby omitting the follow-up polishing process; and the production cost is very low, the yield is very high, no mark of the pouring opening exists on the front face of the product, the whole product is smooth, the texture is uniform, and the quality is very good.
Description
Technical field
The utility model belongs to mould applications, particularly relates to a kind of washing machine cover lid front and back frame mould.
Background technology
Frame mould is divided into patrix (the positive corresponding half module of front and back frame) and counterdie (half module that the frame back side, front and back is corresponding) before and after the washing machine cover lid; But the running channel of frame mould all is located at patrix before and after the washing machine cover lid of prior art; And the running channel that is provided with like this makes mould after cast; The vestige of cast gate is left in the front of the product of moulding, needs follow-up polishing operation to handle, otherwise hand and rough phenomenon will occur scraping; Even after handling through subsequent handling simultaneously, still having than other position of the gate location of handling is poor, yield rate is lower.
Summary of the invention
The utility model provides a kind of product front that makes not leave gate vestiges to above problem, also need not the higher washing machine cover lid front and back frame mould of follow-up polishing operation and yield rate.
The utility model overcomes the above problems used technical scheme: a kind of washing machine cover lid front and back frame mould with following structure is provided; It comprises upper die and lower die; Described patrix and counterdie are fitted and are formed die cavity, and described counterdie is provided with the running channel that is communicated with die cavity.
After adopting above structure, compared with prior art, the utility model is because described counterdie is provided with the running channel that is communicated with die cavity, and the counterdie correspondence is again the back side of front and back frame; Be the back side of cast gate frame,, then need not cast gate is handled that this has also just saved follow-up polishing operation so the vestige of cast gate is stayed the back side on the product of die casting moulding in front and back; Production cost is lower, and yield rate is higher, and just there is not gate vestiges in the front of product yet; Whole smooth, texture is consistent, and quality is better.Therefore the utility model can make the product front not leave gate vestiges, and it is higher also to need not follow-up polishing operation and yield rate.
Description of drawings:
Accompanying drawing is the structural representation of frame mould before and after the utility model washing machine cover lid.
As shown in the figure: 1, patrix, 2, counterdie, 3, running channel, 4, die cavity.
The specific embodiment:
Below in conjunction with the accompanying drawing and the specific embodiment, the utility model done further describing:
Like frame mould before and after a kind of washing machine cover lid shown in the drawings; It comprises patrix 1 and counterdie 2; Described patrix 1 is fitted with counterdie 2 and is formed die cavitys 4, and described counterdie 2 is provided with the running channel 3 that is communicated with die cavity 4, and two of operated by rotary motion are die cavity 4 independently; Each die cavity 4 equal correspondence is provided with two running channels 3, and these two running channels 3 center line along its length is symmetrically distributed.
During use, with counterdie 2 closures and after fitting, the injecting head of injection machine stretches into from the opening part of running channel 3 in counterdie 2 bottoms, and is concordant with the bottom of die cavity 4 until the end of injecting head, carries out injection moulding at last again and gets final product at patrix 1
Above embodiment is merely the preferred embodiment of the utility model, and the utility model is not limited only to above embodiment and also allows other structural change, allly in the utility model rights to independence claimed range, changes, and all belongs to the utility model protection domain.
Claims (1)
1. frame mould before and after the washing machine cover lid, it comprises patrix (1) and counterdie (2), described patrix (1) and counterdie (2) the formation die cavity (4) of fitting, it is characterized in that: described counterdie (2) is provided with the running channel (3) that is communicated with die cavity (4).
