Abstract
The utility model relates to a novel hot sprue component which comprises a hot sprue main body and a sprue bush, wherein the sprue bush is sleeved on the front end part of the hot sprue main body in a sleeving manner, and is fixedly arranged on a die cavity of a die; a first heat insulation space is formed between the hot sprue main body and the sprue bush; a second heat insulation space is formed between the front end of the sprue bush and the die cavity of the die; a sealed part is arranged between the tapered head of the hot sprue main body and the sprue bush, and is positioned at the rear end of the tapered head of the hot sprue main body. According to the novel hot sprue component, the sealed position of the hot sprue main body and the sprue bush is away from a sprue, and two heat insulation layers are also arranged, so that high temperature in the sprue can be ensured to ensure that a product is high in flowability and free of cold glue, and low temperature outside the sprue can also be ensured to avoid casting and drawing, and therefore, the novel hot sprue component can be applied to common plastics as well as high-temperature engineering plastics.
Description
Technical field
The utility model relates to the hot nozzle assembly of a kind of Novel glue, especially relates to a kind of hot nozzle assembly that can be applied to high-temperature engineering plastics, belongs to injection mold component technology field.
Background technology
In injection mold, often use hot mouth, the hot nozzle assembly of commonly using in prior art, as shown in Figure 1, comprises hot mouth main body 1, heating core 2, heating core fixed cap 3, described heating core fixed cap 3 is fixed on heating core 2 in hot mouth main body 1; The axial middle part of described hot mouth main body 1 and heating core 2 is provided with fluid passage 4.When work, hot nozzle assembly is fixed on mold cavity 5, form two sealing positions, place, see the first sealing glue position 6 and the second sealing glue position 7 in figure, because two sealing positions, place are all near Jiao Kou position, in order not damage Jiao Kou, hot mouth head temperature is on the low side, therefore for the higher plastics of temperature requirement, easily there is the problem of not plastic emitting or cold glue, cause product unstable; So hot nozzle assembly conventional in prior art is only suitable for producing common plastics, is not suitable for production engineering plastics.
Utility model content
The utility model object is that a kind of a kind of Novel hot nozzle assembly that can be applied to high-temperature engineering plastics is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of Novel hot nozzle assembly, comprises hot mouth main body, sprue bush; Described sprue bush is set in the leading section of described hot mouth main body; Described sprue bush is fixedly installed on mold cavity; Between described hot mouth main body and sprue bush, be provided with the first insulated space; Between the front end of described sprue bush and mold cavity, be provided with the second insulated space; Between the conical nose of described hot mouth main body and sprue bush, be provided with sealing glue position.
Preferably, described sealing glue position is positioned at the rear end of the conical nose of hot mouth main body.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
In a kind of Novel hot nozzle assembly of the utility model scheme, be positioned at the rear end of the conical nose of hot mouth main body due to described sealing glue position, therefore the sealing position of hot mouth main body and sprue bush from Jiao Kou away from, be provided with again the two-layer thermal insulation layer that the first insulated space and the second insulated space form, both reduced the internal heat loss of hot mouth portion, guaranteed again that mold cavity hull-skin temperature was lower; This structure can guarantee that glue mouth internal temperature is high, good product mobility, and not cold glue, can make again glue mouth external temperature low, does not salivate wire drawing; Therefore a kind of Novel hot nozzle assembly described in the utility model, can be applied to common plastics, can be applied to again high-temperature engineering plastics.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 2 is the assembly structure schematic diagram of the hot mouth of a kind of Novel glue described in the utility model and mold cavity;
Wherein: 1, hot mouth main body; 2, heating core; 3, heating core fixed cap; 4, fluid passage; 5, mold cavity; 6, the first sealing glue position; 7, the second sealing glue position; 8, sprue bush; 9, the first insulated space; 10, the second insulated space; 11, sealing glue position.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 2 is a kind of Novel hot mouth described in the utility model, comprises hot mouth main body 1, sprue bush 8; Described sprue bush 8 is set in the leading section of described hot mouth main body 1; Described sprue bush 8 is fixedly installed on mold cavity 5; Between described hot mouth main body 1 and sprue bush 8, be provided with the first insulated space 9; Between the front end of described sprue bush 8 and mold cavity 5, be provided with the second insulated space 10; Between the conical nose of described hot mouth main body 1 and sprue bush 8, be provided with sealing glue position 11; Described sealing glue position 11 is positioned at the rear end of the conical nose of hot mouth main body 1.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
In a kind of Novel hot nozzle assembly of the utility model scheme, be positioned at the rear end of the conical nose of hot mouth main body due to described sealing glue position, therefore the sealing position of hot mouth main body and sprue bush from Jiao Kou away from, be provided with again the two-layer thermal insulation layer that the first insulated space and the second insulated space form, both reduced the internal heat loss of hot mouth portion, guaranteed again that mold cavity hull-skin temperature was lower; This structure can guarantee that glue mouth internal temperature is high, good product mobility, and not cold glue, can make again glue mouth external temperature low, does not salivate wire drawing; Therefore a kind of Novel hot nozzle assembly described in the utility model, can be applied to common plastics, can be applied to again high-temperature engineering plastics.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
