Abstract

The utility model relates to a kind of sprue bush structure, has fixed head, de-material water gap plate and sprue bush; Described sprue bush is fixedly installed on fixed head, and de-material water gap plate is arranged on the lower surface of fixed head, and sprue bush stretches in de-material water gap plate; Described sprue bush comprises tank for accommodating injection-moulding nozzle and sprue; Described tank is coaxial with sprue and communicate, and tank is cast gate with the sprue place of communicating; Described cast gate lower than fixed head lower surface and be positioned at de-material water gap plate.The utility model reduces sprue length, not only saves materials and reduces cost, and is conducive to the loss reducing injection pressure, improves Forming Quality.

Description

A kind of sprue bush structure
Technical field
The utility model relates to die casting field, particularly a kind of sprue bush structure.
Background technology
Sprue bush is again sprue bushing, Guan Zui, cast gate mouth, is to allow the plastic material of melting be injected into the runner part of mould inside from the nozzle of injection machine, for connecting into the metal fittings of mould and injection machine.Sprue bush is generally fixed on fixed head also through fixed head and de-material water gap plate.The cast gate of traditional sprue bush is generally all positioned at fixed head, makes sprue relatively long like this, not only increases materials being fabricated cost, and can increase the loss of injection pressure more to a certain extent, has certain influence to the Forming Quality of product.
Utility model content
The purpose of this utility model is to provide a kind of saving materials, and injection pressure loss is little, and anti-wire-drawing effect is good, is conducive to the sprue bush structure improving forming quality of products.
The technical scheme realizing the utility model object is: the utility model has fixed head, de-material water gap plate and sprue bush; Described sprue bush is fixedly installed on fixed head, and de-material water gap plate is arranged on the lower surface of fixed head, and sprue bush stretches in de-material water gap plate; Described sprue bush comprises tank for accommodating injection-moulding nozzle and sprue; Described tank is coaxial with sprue and communicate, and tank is cast gate with the sprue place of communicating; Described cast gate lower than fixed head lower surface and be positioned at de-material water gap plate.
The distance of the lower surface of above-mentioned cast gate and fixed head is 6-10mm.
As preferably, the distance of the lower surface of above-mentioned cast gate and fixed head is 8mm.
On the outer circumference surface of above-mentioned sprue bush, the position of corresponding cast gate is provided with circular radiating groove.
The utility model has positive effect: cast gate is arranged in de-material water gap plate by (1) the utility model, shorten the length of sprue, not only reduce making materials, and decrease the loss of injection pressure, while reducing manufacturing cost, also improve the Forming Quality of product; (2), when in the utility model, the distance of the lower surface of cast gate and fixed head is 6-10mm, effect is best; (3) the utility model arranges circular radiating groove in the position of corresponding cast gate, effectively can prevent the wire drawing phenomenon of product.
Accompanying drawing explanation
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of sprue bush in the utility model.
Detailed description of the invention
See Fig. 1 and Fig. 2, the utility model has fixed head 1, de-material water gap plate 2 and sprue bush 3; Described sprue bush 3 is fixedly installed on fixed head 1, and de-material water gap plate 2 is arranged on the lower surface of fixed head 1, and sprue bush 3 stretches in de-material water gap plate 2; Described sprue bush 3 comprises tank 31 for accommodating injection-moulding nozzle and sprue 32; Described tank 31 is coaxial with sprue 32 and communicate, and tank 31 is cast gate with sprue 32 place of communicating; Described cast gate lower than fixed head 1 lower surface and be 8mm with the distance of the lower surface of fixed head 1; On the outer circumference surface of described sprue bush 3, the position of corresponding cast gate is provided with circular radiating groove 33, to prevent wire drawing.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
