Description
Technical field
The utility model belongs to injection mold field, particularly relates to one and is applied to Large Scale Cold runner injection molding die.
Background technology
From the structure of the injection mold of present situation, the surrounding of sprue, namely to store Hot phenomenon often the most serious for sprue bush part.This is because sprue bush directly contacts with the injection molding machine nozzle of high temperature, it is the position being injected into high-temperature fusion resin in mould at first.Especially run into the mould of thin-walled, small sized product, owing to being difficult to take cooling provision to sprue bush, primary flow channel area usually more expends cool time than product section.
The cooling system of current mould generally all leaves on A, B plate, has minority to have cooling system on sprue bush, but these cooling systems are all for the cooling in die cavity usually.So far, industry does not pay attention to the cooling to sprue always, in fact, in the approach of whole injection moulding melt flows, sprue temperature is the highest, and cool time is the longest, cause injection molding cycle long, now, the sprue of high temperature can cause melt temperature near it too high, goods nearly cast gate position local contraction is large, distortion is serious, therefore tackles sprue when condition is permitted and rationally cool, and can shorten molding cycle, reduce goods inside and open defect, to reduce production cost.
Utility model content
For not enough in above-mentioned technology, the utility model provides a kind of water pipe sprue bush that directly can cool sprue, and the use of this water pipe sprue bush, can shorten molding cycle, enhance productivity, thus reaches the object reducing production cost.
For achieving the above object, the utility model provides a kind of opening shape water pipe sprue bush, comprises the first sprue bush, the second sprue bush, the first waterproof apron, the second waterproof apron and sprue; Described first sprue bush comprises integrated column jacket and the first panel, described column jacket is provided with storage tank, described second sprue bush comprises integrated inner prop and the second panel, described inner prop assigns in storage tank, be provided with the first waterproof apron between the bottom of described inner prop and the bottom of storage tank, between the top of described storage tank and the second panel, be provided with the second waterproof apron; The outer surface of described inner prop is provided with many matrix fortune tanks, and the inwall of described matrix fortune tank and column jacket forms waterway channel, and described first panel is provided with the water inlet and delivery port that are communicated with waterway channel; Described sprue runs through on the first sprue bush and the second sprue bush, and sprue is positioned on the axis of the first sprue bush and the second sprue bush.
Wherein, described first panel is provided with multiple first screwed hole, described second panel is provided with and the first screwed hole the second screwed hole one to one, and the first screwed hole is connected by trip bolt with the second screwed hole, is provided with the 3rd waterproof apron between described first screwed hole and the second screwed hole.
Wherein, described first screwed hole is through hole, and described second screwed hole is blind hole, and the afterbody of described trip bolt is fixed in blind hole through after through hole.
Wherein, the cross section of the matrix fortune tank of described inner prop is semicircle.
Wherein, described first panel and the second panel are also provided with the spirality water route matched with waterway channel.
The beneficial effects of the utility model are: compared to prior art, the opening shape water pipe sprue bush that the utility model provides, in the first sprue bush inside, sprue is set, the outer surface of the inner prop of the first sprue bush is provided with many matrix fortune tanks, the inwall of matrix fortune tank and column jacket forms waterway channel, directly cools sprue.The mode of directly cooling is adopted to carry out mold cools down, to solve in injection moulding process unheeded sprue cooling problem always, be conducive to the molding cycle shortening goods, improve the efficiency of production and processing, reach the object of controlling cost, also reduce the energy loss of lathe, reduce the local contraction near product sprue, reduce distortion; Improve product quality simultaneously, also improve the efficiency of processing.
Accompanying drawing explanation
The profile of the opening shape water pipe sprue bush that Fig. 1 provides for the utility model.
Main element symbol description is as follows:
11, the first sprue bush 12, second sprue bush
13, the first waterproof apron 14, second waterproof apron.
Detailed description of the invention
In order to more clearly state the utility model, below in conjunction with accompanying drawing, the utility model is further described.
Refer to Fig. 1, the opening shape water pipe sprue bush that the utility model provides, comprise the first sprue bush 11, second sprue bush 12, first waterproof apron 13, second waterproof apron 14 and sprue; First sprue bush 11 comprises integrated column jacket and the first panel, column jacket is provided with storage tank, second sprue bush 12 comprises integrated inner prop and the second panel, inner prop assigns in storage tank, be provided with the first waterproof apron 13 between the bottom of inner prop and the bottom of storage tank, between the top of storage tank and the second panel, be provided with the second waterproof apron 14; The outer surface of inner prop is provided with many matrix fortune tanks, and the inwall of matrix fortune tank and column jacket forms waterway channel, and the first panel is provided with the water inlet and delivery port that are communicated with waterway channel; Sprue runs through on the first sprue bush 11 and the second sprue bush 12, and sprue is positioned on the axis of the first sprue bush 11 and the second sprue bush 12.
Compared to prior art, the opening shape water pipe sprue bush that the utility model provides, arranges sprue in the first sprue bush 11 inside, and the outer surface of the inner prop of the first sprue bush 11 is provided with many matrix fortune tanks, the inwall of matrix fortune tank and column jacket forms waterway channel, directly cools sprue.Adopt the mode of directly cooling to carry out mold cools down, to solve in injection moulding process unheeded sprue cooling problem always, be conducive to the molding cycle shortening goods, reduce the energy loss of lathe, reduce the local contraction near product sprue, reduce distortion; Improve product quality simultaneously, also improve the efficiency of processing.
The opening shape water pipe sprue bush that the utility model provides, improves sprue bush temperature, improves product quality, shortens injection time, prevents the phenomenons such as runner wire drawing.By shortening the time of sprue, greatly reducing the inject time of whole product, being conducive to reducing job costs, the call that the company of reaching increases income and decreases expenditure, in addition, the processing of this sprue bush is very convenient, without the need to being printed the processing of contour cost technology by 3D, its processing method is simple, easy to assembly.
