Abstract
The invention discloses a multifunctional television back shell mould. The multifunctional television back shell mould is characterized in that an upper mould (1) and a lower mould (4) form a cavity (2); a plurality of glue injection holes (3) are distributed in two sidewalls in the cavity (2); the lower mould (4) is provided with recessed chambers (9); mould cores (10) matching with the recessed chambers (9) are arranged in the cavity (2) and fixed on the lower surface of the upper mould (1); steam pipelines (5) and a lifting platform (7) are arranged in the lower mould (4); the lifting platform (7) is fixedly connected with thin type hydraulic jacks (6); and cooling water pipelines (11) are arranged in the upper mould (1). The multifunctional television back shell mould has a simple and reasonable structure and realizes glue injection through the glue injection holes, which enables glue injection to be uniform; the steam pipelines are beneficial for uniform distribution of an injection molding material to each corner of the mould and allow molding to be uniform; and the S-shaped horizontally-distributed cooling water pipelines enable a molded shell to be rapidly cooled, so time is saved and production efficiency of the shell is improved.
Description
Technical field
The invention belongs to technical field of mold, be specifically related to a kind of multi-function TV set back cover mould.
Background technology
Mould makes blank become under external force to have the instrument of the product of given shape and size.Be widely used in stamping-out, die forging, cold-heading, extruding, metallic sintered products compacting, compression casting, and in the compression moulding of goods such as engineering plastics, rubber, pottery or the formed machining of injection moulding.Mould has specific profile or cavity shape, and the contour shape that application has cutting edge can make blank be separated by outline line shape.Application cavity shape can make blank obtain corresponding three-dimensional shape.Take out product time separately, make blank inject mold cavity (2) when closing up and be shaped.Mould is precision instrument, complex-shaped, bears the expansive force of blank, all has higher requirements to structural strength, rigidity, case hardness, surface roughness and machining accuracy, and the development level that mould is produced is one of important symbol of machine-building level.
Good mould structure is the prerequisite that excellent product manufactures, mould structure and product structure are analyzed in all directions, such as: mold releasability gradient, the epitome of product surface, the design of running gate system, the design etc. of cooling system, the design of cooling system is the work than more complicated, namely to consider the uniformity of cooling effect and cooling, consider that cooling system affects the particular location of cooling system and the determination of size to mold integral structure again.
Just these series of problems should be analyzed when Design of Dies, mould adopts the mode of recirculated water to flow at each position of mould inside, therefore, how to produce a kind of multi-function TV set back cover mould, reduce cool time during injection moulding, improve the production efficiency of product, greatly reduce production cost, have important practical significance.
Summary of the invention
The object of the present invention is to provide a kind of multi-function TV set back cover mould, simple and reasonable, injecting glue is even, be conducive to each corner that injected plastics material is distributed to mould uniformly, make uniform in shaping, pass into cold water at cooling water channel, make molded housing accelerating cooling, save time, improve the production efficiency of product.
The technical scheme that the present invention takes is:
A kind of multi-function TV set back cover mould, comprise cope match-plate pattern (1) and lower bolster (4), it is characterized in that, described cope match-plate pattern (1) and lower bolster (4) form die cavity (2), a distributive plural hole for injecting glue (3) on two side in die cavity (2), described lower bolster (4) is provided with cavity (9), the core (10) matched with cavity (9) is provided with in die cavity (2), core (10) is fixed on the lower surface of cope match-plate pattern (1), jet chimney (5) and lifting platform (7) is provided with in described lower bolster (4), lifting platform (7) is fixedly connected with Thin type hydraulic jack (6), cooling water channel (11) is provided with in described cope match-plate pattern (1).
Described cope match-plate pattern (1) is connected by guide pillar (8) with lower bolster (4).
Described hole for injecting glue (3) horizontal distribution, spacing is identical.
Described jet chimney (5) is distributed horizontally in lower bolster (4) in " U " type.
Described cooling water channel (11) is distributed horizontally in cope match-plate pattern (1) in " S " type.
Described Thin type hydraulic jack (6) is arranged on four base angles place of lower bolster (4).
Described cooling water channel (11) is provided with many, equidistantly arranges.
Beneficial effect of the present invention is:
Of the present invention simple and reasonable, in die cavity (2), on two side, a plurality of hole for injecting glue of horizontal distribution carries out injecting glue, make injecting glue even, jet chimney in " U " type horizontal distribution in lower bolster is used for carrying out high-temperature process to product, injected plastics material is made to keep high temperature, be conducive to each corner that injected plastics material is distributed to mould uniformly, make uniform in shaping, after formed product, cold water is passed at the cooling water channel of " S " type horizontal distribution, make molded housing accelerating cooling, save time, improve the production efficiency of product, by liftout attachment, shaping housing is outwards ejected, mechanization degree is high, have a extensive future.
