Abstract
The invention discloses a double-valve-needle hot nozzle which comprises a hot nozzle main body and a glue inlet hole which is arranged at the hot nozzle main body. The double-valve-needle hot nozzle is characterized in that the hot nozzle main body is provided with two glue injection runners, and each glue injection runner is provided with a set of valve needle assembly; the glue inlet hole is connected with the two glue injection runners respectively through two glue inlet runners. The double-valve-needle hot nozzle provided by the invention has the two glue injection runners and corresponding two sets of valve needle assemblies which synchronously work to carry out glue injection on a die cavity. Compared with the existing single-valve-needle hot nozzle, the glue injection has no dead angle, the raw materials are evenly distributed, the product thickness can be precisely controlled easily, particularly the double-valve-needle hot nozzle is suitable for producing special double glue inlet products which have high requirement on the molding thickness accuracy at present, for example the medical 'easily folded cover'product.
Description
Technical field
The invention belongs to needle valve type injection-moulding device technical field, be specifically related to the hot mouth of a kind of bivalve pin.
Background technology
Mostly the hot mouth that uses during Shooting Technique is produced at present is the hot mouth of single valve pin, this hot mouth only has an injecting glue runner and a sleeving valve needle assemblies, can only be from one-sided with the material injecting mould die cavity during work, shortcoming is to produce easily the injecting glue dead angle, cause feed distribution uneven, cause the product material became uneven after the moulding, of poor quality.Especially an existing class has special pair of accurate requirement to advance the glue goods for molding thickness, and for example medical " easily fold " if adopt the conventional hot mouth of single valve pin to produce, often can't obtain preferably product quality.
Summary of the invention
The present invention seeks to: provide a kind of bivalve pin hot mouth, this hot mouth has two injecting glue runners and corresponding two sleeving valve needle assemblies work asynchronously to the mold cavity injecting glue, can accomplish injecting glue without the dead angle, and feed distribution is even.
Technical scheme of the present invention is: the hot mouth of a kind of bivalve pin, comprise hot mouth main body and the glue feeding opening of being located on the hot mouth main body, it is characterized in that being provided with two injecting glue runners in the described hot mouth main body, and in every injecting glue runner, being equipped with a sleeving valve needle assemblies, described glue feeding opening enters the solation road by two and links to each other with described two injecting glue runners respectively.
Further preferred, two injecting glue runner Parallel Symmetric settings in hot mouth main body described in the present invention.
Further preferred, glue feeding opening described in the present invention is the mid point arranged off-centre with respect to the entrance center line of two injecting glue runners in hot mouth main body top.
Further preferred, glue feeding opening described in the present invention is positioned on the perpendicular bisector of entrance center line of two injecting glue runners.
Further preferred, two are entered the solation road and are symmetrical arranged in hot mouth main body described in the present invention, and every is entered the solation road and all tilts to intersect with the corresponding injecting glue runner that links to each other.
The same with routine techniques, the assembly of needle described in the present invention comprises that holding is at the valve needle cover on injecting glue runner top and the needle that cooperates with valve needle cover.
Advantage of the present invention is:
The hot mouth of this bivalve pin provided by the invention has two injecting glue runners and corresponding two sleeving valve needle assemblies work asynchronously to the mold cavity injecting glue, compare the hot mouth of existing single valve pin, can accomplish that injecting glue is without the dead angle, feed distribution is even, be easier to the product thickness is accurately controlled, especially be fit to produce and existingly advance glue goods, for example medical " easily fold " series products for higher special two of molding thickness required precision.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is main cutaway view of the present invention;
Fig. 2 is the A-A profile of Fig. 1;
Fig. 3 is top view of the present invention.
Wherein: 1, hot mouth main body; 2, glue feeding opening; 3, injecting glue runner; 3a, entrance; 4, enter the solation road; 5, valve needle cover; 6, needle.
The specific embodiment
Embodiment: in conjunction with Fig. 1-shown in Figure 3, the hot mouth of this bivalve pin that present embodiment provides, it has hot mouth main body 1 and the glue feeding opening 2 of being located on the hot mouth main body 1, improvement is: be provided with two injecting glue runners 3 in the described hot mouth main body 1, and in every injecting glue runner 3, being equipped with a sleeving valve needle assemblies, described glue feeding opening 2 enters solation road 4 by two and links to each other with described two injecting glue runners 3 respectively.
The assembly of needle described in the present embodiment is made of at the valve needle cover 5 on injecting glue runner 3 tops and the needle 6 that cooperates with valve needle cover 5 holding with routine techniques is the same.
Two injecting glue runners 3 are in hot mouth main body 1 interior Parallel Symmetric setting described in the present embodiment.Described glue feeding opening 2 is the mid point arranged off-centre with respect to the entrance 3a line of centres of two injecting glue runners 3 in hot mouth main body 1 top, and is positioned on the perpendicular bisector of the entrance 3a line of centres of two injecting glue runners 3.
Two are entered solation road 4 and are symmetrical arranged in hot mouth main body 1 described in the present embodiment, and every is entered solation road 4 and all tilts to intersect with the corresponding injecting glue runner that links to each other 3.
The hot mouth of this bivalve pin provided by the invention has two injecting glue runners 3 and corresponding two sleeving valve needle assemblies work asynchronously to the mold cavity injecting glue, compare the hot mouth of existing single valve pin, can accomplish that injecting glue is without the dead angle, feed distribution is even, be easier to the product thickness is accurately controlled, especially be fit to produce and existingly advance glue goods, for example medical " easily fold " series products for higher special two of molding thickness required precision.
Certainly above-described embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the people who is familiar with technique can understand content of the present invention and according to this enforcement, can not limit protection scope of the present invention with this.All modifications that the Spirit Essence of main technical schemes is done according to the present invention all should be encompassed within protection scope of the present invention.
