Abstract
The utility model relates to a hot runner sprue structure of a mould. The hot runner sprue structure comprises a cavity, a sprue runner communicated with the cavity and a nozzle extending into the sprue runner, wherein the sprue runner is formed in the back surface of a front mould core; the cavity is formed in the parting surface of the front mould core; a sunken platform is arranged at an opening of the sprue runner; a step site is arranged on the nozzle; the minimum value of a gap between the bottom surface of the sunken platform and the step site is 0.08mm; an assembly gap of 3mm-5mm is formed between the nozzle and the sprue runner. According to the hot runner sprue structure, the phenomenon of yellowing, color mixing or brightening in a gate area of a mould injection product is overcome, and the product quality is improved.
Description
Technical field
The utility model relates to a kind of mold hot flow pouring gate structure.
Background technology
Along with consumer is more and more higher to the requirement of product appearance, the application of Hot runner Technology in die industry is also more and more extensive.Yet because hot flow path nozzle temperature is higher than mold temperature, cause position, mould mouth of a river heat to be concentrated, cause product jaundice, colour mixture or shinny.
Summary of the invention
For overcoming the problem of the deficiencies in the prior art and existence, the utility model provides a kind of position jaundice of mold injection water port of product, colour mixture or shinny phenomenon of efficiently solving, and has promoted the mold hot flow pouring gate structure of product quality.
The utility model is achieved through the following technical solutions:
A kind of mold hot flow pouring gate structure, comprise die cavity, the pouring head communicating with die cavity and stretch into the nozzle of pouring head, described pouring head is opened in the front cavity back side, described die cavity is opened in front cavity die joint, described pouring head opening part is provided with a heavy stand, described nozzle is provided with a step position, and the minimum clearance value between heavy stand bottom surface and step position is 0.08mm; Between described nozzle and pouring head, be provided with fit-up gap, fit-up gap value is 3-5mm.
The mold hot flow pouring gate structure that the utility model provides, is provided with 3-5mm gap width between nozzle and pouring head, avoid nozzle mold damage when expanded by heating, also avoids the plastic cement glue that overflows from gap simultaneously; Nozzle is provided with a step position, and the minimum clearance value between heavy stand bottom surface and step position is 0.08mm, avoids the nozzle of high temperature directly to contact with mould, causes position, mould mouth of a river heat to be concentrated, and causes product jaundice, colour mixture or shinny, has guaranteed product quality.
Accompanying drawing explanation
Fig. 1 is the inner nozzle of the utility model and hot flow path assembly structure schematic diagram.
In figure: 1-front cavity, 2-die cavity, 3-pouring head, 4-nozzle, 5-heavy stand, 6-step position.
The specific embodiment
Understanding for the ease of those skilled in the art, is described in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of mold hot flow pouring gate structure, comprise die cavity 2, the pouring head 3 communicating with die cavity 2 and the nozzle 4 that stretches into pouring head 3, described pouring head 3 is opened in front cavity 1 back side, described die cavity 2 is opened in front cavity 1 die joint, described pouring head 3 opening parts are provided with a heavy stand 5, and described nozzle 2 is provided with a step position 6, and the minimum clearance value between heavy stand 5 bottom surfaces and step position 6 is 0.08mm; Between described nozzle 4 and pouring head 3, be provided with fit-up gap, fit-up gap value is 3-5mm.
During the utility model work, the plastic cement of high temperature sprays and enters die cavity 2 from nozzle 4, and nozzle 4 dwindles because of the gap between expanded by heating and pouring head 3, and the set gap width of the utility model is 3-5mm, not only avoid nozzle 4 mold damage when expanded by heating, also avoid the plastic cement glue that overflows from gap simultaneously; Nozzle 4 can extend when expanded by heating, between nozzle 4 step positions 6 and heavy stand 5 bottom surfaces, be provided with the gap width of 0.08mm, avoiding mould expanded by heating and nozzle 4 produced by thermal stretching directly contacts, cause position, mould mouth of a river heat to be concentrated, cause product jaundice, colour mixture or shinny, guaranteed product quality.
The content of mentioning in above-described embodiment is not to restriction of the present utility model, is not departing under the prerequisite of inventive concept of the present utility model, and any apparent replacement is all within protection domain of the present utility model.
