Abstract
The utility model discloses an exhaust meshed moving die insert which comprises an insert body, multiple exhaust inserts and multiple matching inserts. The insert body is provided with a cavity position, and the matching inserts and the exhaust inserts are arranged on the cavity position crosswise and sequentially. The exhaust meshed moving die insert is rational in structural design, easy to process and manufacture, effectively shortened in production cycle and lowered in production cost and comprises multiple exhaust inserts and multiple matching inserts, so that a modularized structural design is formed; chamfers on the exhaust inserts and the matching inserts can match with each other or match with the cavity position to form exhaust passages, so that air trapping of products during injection molding of meshes of the plastic products can be avoided well, flowing of smelt glue is improved, smelt glue filling of the products in dense mesh areas can be normally performed, and finished production with high appearance quality and acceptance rate can be obtained; and vent grooves and vent passages are arranged, so that vent effects are further enhanced to guarantee smooth venting, and overall product beautifulness can be effectively improved.
Description
Technical field
The utility model relates to a kind of mold insert, is specifically related to a kind of exhaust mesh dynamic model mold insert that is applied to injection mold.
Background technology
Along with developing rapidly with living standards of the people of panel TV set improves constantly, people also day by day all increase the quality of television set and the requirement of beautifying and decorating gradually.Meanwhile the surface quality of the speaker net of panel shell of television requires high.Spacing between the loudspeaker mesh is little, and the narrowest place, the glue position thigh between Kong Yukong is merely 0.8mm, and hole number generally reaches more than thousand; In the injection moulding production process, produce and be stranded gas, cause the melten gel flow difficulties, make the melten gel of mesh compact district fill and normally to carry out, be easy to generate injection mo(u)lding defectives such as lack of fill, weld bond, be difficult to obtain the good finished product of exterior quality.
Be to adopt the mode that the Shooting Technique muscle improves injecting condition or blind hole is set is set realizes improving flowing of melten gel at present in the main way that solves the injection moulding difficulty of loudspeaker mesh plastic parts, improve its forming defect.So need more workman and processing mechanical apparatus, complex process, the process-cycle is long, cost is high and be difficult to guarantee end product quality, and product appearance is very not attractive in appearance.Research and develop a kind of can the solution for this reason and produce tired gas in the injection moulding production process, avoid technical barriers such as melten gel flow difficulties, and the high injection mold of product qualified rate is work as gesture required.
The utility model content
The purpose of the utility model is, to above-mentioned deficiency, provides a kind of reasonable in design, exhaust smooth and easy, avoids producing and is stranded the gas phenomenon, effectively guarantees the exhaust mesh dynamic model mold insert of product quality.
For realizing above-mentioned purpose, the technical scheme that the utility model provided is:
A kind of exhaust mesh dynamic model mold insert, it comprises a mold insert main body, and it also comprises a plurality of exhaust mold inserts and a plurality of cooperation mold insert, and said mold insert main body is provided with position, a chamber, and said cooperation mold insert, exhaust mold insert group cross arrangement successively are arranged on the position, said chamber.
Said exhaust mold insert is a square block; The bottom Ge Bian of this square block is provided with chamfering; This chamfering and the said exhaust passage that forms when cooperating mold insert and/or position, chamber to cooperate; The left and right sides sidewall of said square block respectively is provided with an air discharge duct, and the lower end of this air discharge duct is extended vertically downward and is connected on the chamfering of side of its bottom, the upper end of this air discharge duct be provided with one it is connected with the external world air channel.
The two bottom sides symmetry of said cooperation mold insert is recessed; Make the centre position convex to form a location boss; The sides of this positioning boss is provided with chamfering; The two bottom sides limit of said cooperation mold insert is provided with chamfering, and on said main mold insert, is provided with one and can makes this chamfering and the extraneous airway that is connected, and three air discharge ducts are respectively arranged on the front and back sidewall of this cooperations mold insert side by side; The lower end of this air discharge duct is extended vertically downward and is connected on the chamfering of side of its bottom, the upper end of this air discharge duct be provided with one it is connected with the external world air channel;
The quantity of said exhaust mold insert is 3, and the quantity of said cooperation mold insert is 4.
The beneficial effect of the utility model is: the utility model reasonable in design, include a plurality of exhaust mold inserts and a plurality of cooperation mold insert, and form the modular construction design, be easy to processing and manufacturing, effectively shorten the production cycle, reduce production costs; And exhaust mold insert and cooperate chamfering on the mold insert to cooperatively interact or cooperates with the position, chamber and form the exhaust passage, can avoid the plastic cement products mesh in injection moulding process, to produce tired gas phenomenon preferably, improve the mobile of melten gel; Guarantee that product normally carries out in the melten gel filling of mesh compact district, realize obtaining the good finished product of exterior quality, product qualified rate is high; Be provided with air channel and airway in addition; Further strengthen exhaust effect, guarantee that exhaust is smooth and easy, and then effectively improve the whole aesthetic measure of product.
Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.
