Abstract
The utility model relates to an injection mold field, in particular to a novel hot runner structure of a needle valve. The structure comprises a cylinder body. A flange and a bottom base are arranged on two ends of the cylinder body respectively. A main nozzle used for feeding glue is arranged in the cylinder and is fixed on the flange. A valve needle base is fixed on the bottom base. A valve needle for injecting glue is arranged in the vale needle base. A piston which can do reciprocating motion in the cylinder body to extrude the glue from the main nozzle to a valve needle for outputting is arranged in the cylinder body. At least two valve needles are uniformly arranged in the valve needle base. According to the novel hot runner structure, glue is fed through the main nozzle and then injected through a plurality of valve needles, and therefore the single-inlet multi-outlet glue injecting way is formed, and the balance among glue injecting points is improved, products having high requirement on glue injecting balance can be produced favorably, and quality of products is improved.
Description
Technical field
The utility model relates to the injection mold field, especially the novel hot runner structure of needle valve on the injection mold.
Background technology
Generally be that single-point styl valve heat is chewed in the market, single-point styl valve heat is chewed and product is advanced the glue balance is required often to be difficult to reach customer requirement when very high, particularly gear and similar gear member product, require high especially to the injecting glue balance, and it is also very high that product is advanced the glue requirement, and single-point styl valve just is difficult to meet the demands like this.
Summary of the invention
The utility model provides a kind of energy Effective Raise to advance the novel hot runner structure of needle valve of glue balance.
To achieve these goals, the utility model adopts following technical scheme:
It comprises a cylinder body, cylinder body is provided with the first gas-tpe fitting and the second gas-tpe fitting, a flange and a base are installed respectively in described cylinder body two ends, be provided with a main nozzle that is used to into glue in the described cylinder body, main nozzle is fixed on the flange, fix a needle seat on the described base, be provided with the needle for injecting glue in the needle seat, be provided with the piston that glue is squeezed to needle output that advances that can move back and forth in cylinder body main nozzle in the cylinder body, its improvement is: be provided with uniformly at least two needles in the described needle seat.
Preferably, described needle is uniformly distributed on the same circumference.
Preferably, be provided with hot mouth heating collar outside the described needle seat.
Preferably, be provided with hot core around the needle of described needle seat end.
Preferably, be provided with a stop pin between described base and the needle seat.
Preferably, be provided with valve needle cover between the porch of described needle seat and the needle.
Owing to adopted said structure, the novel hot runner structure of needle valve of the utility model advances after the glue by main nozzle, carry out injecting glue by a plurality of needles, form the injecting glue form of singly advancing to have more, improved the balance between each injecting glue point, be conducive to the production and processing to the demanding product of injecting glue balance, improved the quality of product.

Fig. 2 is the A-A cross section structure schematic diagram of the utility model embodiment;
Fig. 3 is the perspective view of the utility model embodiment.
The specific embodiment
Figure and 1-are shown in Figure 3, the novel hot runner structure of needle valve of present embodiment comprises a cylinder body 1, cylinder body is provided with the first gas-tpe fitting 101 and the second gas-tpe fitting 102, a flange 2 and a base 3 are installed respectively in described cylinder body 1 two ends, be provided with a main nozzle 4 that is used to into glue in the described cylinder body 1, main nozzle 4 is fixed on the flange 2, fix a needle seat 5 on the described base 3, be provided with the needle 6 for injecting glue in the needle seat 5, be provided with the piston 7 that glue is squeezed to needle output that advances that can in cylinder body, move back and forth main nozzle in the cylinder body 1, described needle seat 5 interior at least two needles 6 that are provided with uniformly, as shown in the figure, present embodiment specifies structure as an example of four needles example, according to the difference of required converted products also can be suitable increase or reduce needle quantity, to adapt to the needs of processing.
Because the needle valve structure of present embodiment is mainly used in machining gears and similar products, so four needles 6 described in the present embodiment are positioned on the same circumference, and equidistant setting, so can carry out respectively uniformly injection moulding to each position of gear, form a complete gear.
Because what enter this hot runner structure of needle valve is the material of molten condition, in order to keep the molten condition of material, is convenient to injection operation, in the present embodiment, described needle seat 5 outsides are provided with hot mouth heating collar 8.During work, hot mouth heating collar remains the interior temperature of needle seat under a higher temperature environment, flows to keep the smooth and easy of material.
Carry out the fluency that injection moulding is in order further to improve the material outflow, in the present embodiment, around the needle 6 of described needle seat 5 ends, be provided with hot core 9.
Because hot runner structure of needle valve has the conversion that is injected into frequently between the arresting stop when work, inner piston moves back and forth, tend to cause integrally-built shake, in order to keep needle to remain at correct injection moulding position, deviation does not occur, in the present embodiment, be provided with a stop pin 10 between described base 3 and the needle seat 5.
In order to keep the sealing in the piston movement space in the cylinder body, in the present embodiment, be provided with valve needle cover 11 between the porch of described needle seat and the needle.
Present embodiment the first gas-tpe fitting 101 air inlet pushing pistons 7 when work move downward, piston 7 drives needle 6 sealings, then, turn to 102 air inlets of the second gas-tpe fitting by the switching valve air inlet by the first gas-tpe fitting 101, piston 7 moves upward, move needle 6 and up move, this moment, system was opening, carried out injection moulding.
The above only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
