Abstract
The utility model discloses an anti-wire-drawing structure of a sprue bush of a plastic mold, which comprises a sprue bush, and a plastic flowing channel is arranged in the middle of the sprue bush; and the anti-wire-drawing structure is characterized in that one end of the sprue bush is provided with an installing groove, and an anti-wire-drawing spacer which can reduce the thickness of a plastic wall of the tail end of a sprue of the sprue bush so as to achieve an effect of wire-drawing prevention is arranged in the installing groove. The utility model aims to overcome the defects of the prior art, and provides an anti-wire-drawing structure of a sprue bush of a plastic mold, which is simple in structure, and can solve the wire drawing phenomenon in a flowing channel of the plastic mold so as to achieve the purpose of reducing the poor production of products in the process of mold production.
Description
Technical field
The utility model relates to the anti-wire drawing structure of a kind of plastic mould sprue bush.
Background technology
Sprue bush is to let the plastic raw materials of fusing be injected into the part of mould inside from the nozzle of injection machine.When product takes out, chilled runner is taken out as waste material.Existing plastic mould, when the design sprue bush, common way is that sprue bush is designed to common sprue bush as shown in Figure 5, as shown in Figure 6 when product takes out, the runner waste material has the wire drawing phenomenon.Runner have the wire drawing phenomenon can be when next producing product produce badly, increase production cost.
The utility model content
The purpose of the utility model is in order to overcome weak point of the prior art, to provide a kind of simple in structure, can solve plastic mould runner wire drawing phenomenon, when reaching die production, reduces product and produces the anti-wire drawing structure of bad purpose plastic mould sprue bush.
In order to achieve the above object, the utility model adopts following scheme:
A kind of plastic mould sprue bush is prevented the wire drawing structure; Comprise sprue bush; In the middle of described sprue bush, be provided with the gummosis passage; It is characterized in that: on described sprue bush one end, be provided with mounting groove, can reduce the anti-wire drawing partition that the terminal glue wall thickness of sprue bush cast gate is realized anti-wire drawing thereby in described mounting groove, be provided with.
Aforesaid a kind of plastic mould sprue bush is prevented the wire drawing structure; It is characterized in that described sprue bush includes a cover seat; In the middle of described cover seat, be provided with mozzle, on described cover seat, be provided with arc groove, on the cover seat of said mounting groove both sides, be respectively equipped with connecting hole.
Aforesaid a kind of plastic mould sprue bush is prevented the wire drawing structure; It is characterized in that described anti-wire drawing partition is a strip partition; In the middle of described strip partition, be provided with arc notch, described arc notch was fair with described arc groove after described strip partition was arranged on described mounting groove.
Aforesaid a kind of plastic mould sprue bush is prevented the wire drawing structure, it is characterized in that the partition of described anti-wire drawing partition for being made by high hardness material.
In sum, the utility model with respect to its beneficial effect of prior art is:
The utility model is simple in structure, prevents the wire drawing partition terminal the increasing of sprue bush cast gate, to reduce the terminal glue wall thickness of sprue bush cast gate; It is fast to reach the thin cooling of wall, and end cooled off fully when the cast gate waste material took out, and did not produce the wire drawing phenomenon; Do not influence ensuing production, reduce production cost.
Description of drawings
Fig. 1 is the stereogram of the utility model;
Fig. 2 is the decomposing schematic representation of Fig. 1;
Fig. 3 is the user mode reference diagram;
Fig. 4 is the sketch map of the product that adopts the utility model sprue bush and produce;
Fig. 5 is the sketch map of existing sprue bush;
Fig. 6 is the sketch map of wire drawing product.
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment the utility model is further described:
A kind of plastic mould sprue bush shown in Fig. 1 to 4 is prevented the wire drawing structure; Comprise sprue bush 1; In the middle of described sprue bush 1, be provided with gummosis passage 2; On described sprue bush 1 one ends, be provided with mounting groove 3, can reduce the anti-wire drawing partition 4 that the terminal glue wall thickness of sprue bush 1 cast gate is realized anti-wire drawing thereby in described mounting groove 3, be provided with.
Sprue bush 1 described in the utility model includes a cover seat 11, in the middle of described cover seat 11, is provided with mozzle 12, on described cover seat 11, is provided with arc groove 13, on the cover seat 11 of said mounting groove 3 both sides, is respectively equipped with connecting hole 14.
Be illustrated in figure 5 as the terminal glue wall thickness of common sprue bush cast gate; Temperature than higher when runner takes out as waste material end fully cooling produce wire drawing such as Fig. 6; The cast gate end is pulled out very long one section thing that silk thread is the same, on forming nozzle, also has this phenomenon simultaneously.The thing that silk thread is the same when next producing can dash with the plastic raw materials of fusing and fill out the die cavity the inside.It is bad that product is produced, and increases production cost.
The utility model technology is to prevent the wire drawing partition terminal the increasing of sprue bush cast gate, to reduce the terminal glue wall thickness of sprue bush cast gate, reaches the thin cooling of wall soon; End cooled off fully when the cast gate waste material took out; Do not produce the wire drawing phenomenon, do not influence ensuing production, reduce production cost.Anti-wire drawing partition is made with high hardness material, at common sprue bush thin type square groove of terminal processing such as Fig. 3, will prevent that the wire drawing partition is bumped into welding well, and a kind of novel anti-wire drawing sprue bush has just been carried out.Preparation method is simple, and is easy to process.
