Abstract
The invention relates to a needle valve type cold channel silica gel single KEY mould structure which is used for forming a single-KEY product and comprises a mould blank, a front mould arranged on the mould blank, and a rear mould which is opposite to the front mould and arranged on the mould blank, wherein a cavity for forming the product is arranged between the front mould and the rear mould; the die also comprises a guide post and an edge lock for positioning, so that the positioning problem of the traditional die is further solved, and the action deviation of the die in the processing and forming process is further effectively prevented; the needle valve type injection head for liquid injection molding is arranged above the middle of the cavity, so that raw materials are saved, the needle valve type injection head is easy to clean, the molding time is short, and the efficiency is high.
Description
Technical field
The present invention relates to the cold road of a kind of liquid needle valve silica gel list KEY mould structure.
Background technology
The mould of existing shaped article as shown in Figure 3, is generally the mode that glue is advanced at the big mouth of a river.The big mouth of a river is advanced rubber moulding and had following shortcoming: four of (1) .1 sheet list KEY enter the glue position just because of advancing the glue imbalance, and cause single KEY size instability.(2). because big mouth of a river mode is advanced glue, the runner flow distribution plate is to shunt from the centre, be subjected to the flowing velocity time effects of raw material, on the limit 1,4 just do not have 2, and 3 single KEY run the material equilibrium, thereby influence the dimensionally stable of single KEY yet, single KEY size instability directly causes the loading peak force of single KEY inhomogeneous, and the life-span is on the low side.(3). overlap is excessive, and former material waste is big, labor cleaning's burr cost height.In addition, existing mold generally adopts the flat plate mold structure, and mold thickness is thin excessively, and mould easily is out of shape in the hot briquetting process, thereby causes single KEY off-centre, is central point with single KEY promptly, and the left and right sides size is unbalanced, thereby causes loading unbalanced, and the life-span is on the low side.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of economizing in raw materials, long service life, and molding time is short, the cold road of the needle valve that efficient is high silica gel list KEY mould structure.The present invention is achieved through the following technical solutions:
The cold road of a kind of needle valve of the present invention silica gel list KEY mould structure is used for moulding singly-bound product, comprises the mould base, and be arranged on front mould on the mould base, and relative with front mould, be arranged on the back mould on the mould base, be provided with the die cavity of formed product between described front mould and the back mould; Described mould also includes guide pillar and the limit lock that is used to locate; The needle valve that the middle upper part of described die cavity is provided with the liquid ejection formation head that shoots material.
As preferably, described mould adopts plastic cement mould base.
As preferably, described needle-valve can be up and down or front and back control stroke shoot material and sealing.
As preferably, the described head that shoots material is directly aimed at a product die cavity.
The cold road of needle valve of the present invention silica gel list KEY mould structure owing to adopt the needle-valve cold runner to advance glue, has the following advantages: (1). and runner is short, and burr significantly reduce, and wastage of material is few; (2). adopt the intermediate point of every SHEET to advance glue, advance the glue equilibrium, thereby guarantee each single KEY dimensionally stable, loading is stable, and the life-span reaches set designing requirement; (3). molding time shortens, the production capacity of enhancing productivity.In addition, because the standard of employing plastic cement mould base has the following advantages: mold materials is crossed the problem of easy temperature distortion in the solution system structure effectively.Owing to adopt guide pillar and limit locking bit. further solve the orientation problem of traditional moulds, further effectively prevent the action skew in the process of shaping of mould, single KEY is by flat plate mold, become new construction plastic cement mould base, the mould location is accurate, the die material is not yielding, thereby efficiently solves the eccentricity issues of single KEY.Make single KEY dimensionally stable, the loading equilibrium, the life-span reaches the predetermined design requirement.
Description of drawings
In order to be easy to explanation, the present invention is done to describe in detail by following preferred embodiment and accompanying drawing.
Fig. 1 is the front view of the cold road of needle valve of the present invention silica gel list KEY mould structure;
Fig. 2 is the vertical view of the cold road of needle valve of the present invention silica gel list KEY mould structure;
Fig. 3 is the vertical view of the mould of shaped article in the prior art.
The specific embodiment
Extremely shown in Figure 2 as Fig. 1, the cold road of a kind of needle valve of the present invention silica gel list KEY mould structure, be used for moulding singly-bound product, comprise mould base 1, and be arranged on front mould 2 on the mould base 1, and relative with front mould 2, be arranged on the back mould 3 on the mould base 1, be provided with the die cavity 4 of formed product between described front mould 2 and the back mould 3; Described mould also includes guide pillar 5 and the limit lock 6 that is used to locate, and further solves the orientation problem of traditional moulds, further effectively prevents the action skew in the process of shaping of mould; The needle valve that the middle upper part of described die cavity 4 is provided with the liquid ejection formation shoots material (not shown), can economize in raw materials, and very easily cleaning, and molding time is short, the efficient height.Described mould adopts plastic cement mould base, and the mould location is accurate, and the die material is not yielding, thereby efficiently solves the eccentricity issues of single KEY.Make single KEY dimensionally stable, the loading equilibrium, the life-span reaches the predetermined design requirement.Wherein, described needle-valve can be up and down or front and back control stroke shoot material and sealing.The described head that shoots material is directly aimed at product die cavity 4.
The cold road of needle valve of the present invention silica gel list KEY mould structure owing to adopt the needle-valve cold runner to advance glue, has the following advantages: (1). and runner is short, and burr significantly reduce, and wastage of material is few; (2). adopt the intermediate point of every SHEET to advance glue, advance the glue equilibrium, thereby guarantee each single KEY dimensionally stable, loading is stable, and the life-span reaches set designing requirement; (3). molding time shortens, the production capacity of enhancing productivity.Because the standard of employing plastic cement mould base has the following advantages: (1). mold materials is crossed the problem of easy temperature distortion in the solution system structure effectively; (2). adopt guide pillar and limit locking bit. further solve the orientation problem of traditional moulds, further effectively prevent the action skew in the process of shaping of mould, single KEY is by flat plate mold, become new construction plastic cement mould base, the mould location is accurate, the die material is not yielding, thereby efficiently solves the eccentricity issues of single KEY.Make single KEY dimensionally stable, the loading equilibrium, the life-span reaches the predetermined design requirement.
The foregoing description, just an example of the present invention is not to be used for limiting enforcement of the present invention and interest field, the identical or technical scheme that is equal to of the described content of claim all and of the present invention all should be included in the protection domain of the present invention.
