Description
Technical field
The utility model relates to the injection moulding apparatus field, particularly relates to a kind of injection mold hot mouth of single-point needle valve.
Background technology
At present, it is the developing direction of injection moulding industry that injection mold uses TOP-TIP, use hot flow path with respect to traditional cold runner structure mold, have plurality of advantages such as economizing in raw materials, boost productivity, improve product quality, simplification product following process, its weak point is to have increased die cost.Improve the Mould Machining precision, the hot mouth of needle valve is a kind of of more complicated in the TOP-TIP, its operation principle is to drive moving up and down of hot mouth central authorities' needle by gas (oil) cylinder, drive signal (usually by air pressure or oil pressure valve) and link to each other, needle is retreated when injection moulding begins, open injection hole with the injection moulding control signal of injection machine, allow melten gel pass through, when injection moulding finishes, close, and close die cavity, reach the purpose of cutting off Jiao Kou.The hot mouth of single-point needle valve is to be the hot mouth of a kind of needle valve that designs when injection moulding center, needle center and cast gate are centered close to a straight line, and in this case, subject matter is how to drive the intermediate valve needle movement not influence the melten gel proper flow again.
The hot mouth of currently used single-point needle valve mainly contains following three kinds of structures: gas (oil) cylinder that 1, will drive needle-valve wraps in hot mouth outside, and piston is positioned at a peripheral week of hot mouth, and special one or two power transmission shafts drive needles and move up and down in the middle of the piston.Adopt the company of this structure have Korea S YUDO, believe Canadian HUSKY, the EWIKON of Germany etc.The major defect of the hot mouth of single-point needle valve of this structure is a processed complex, and assembling is complicated, and seal is at high temperature worked for a long time, and is very high to the seal requirement, so manufacturing cost is high, expensive.2, gas (oil) cylinder is placed directly over the hot mouth, a large-scale mold insert is done in the cylinder outside, bores the runner hole in mold insert, avoids cylinder and links to each other with the hot mouth of mold insert below, heats whole mold insert with heating rod.Adopt the company of this kind structure to mainly contain gondola THERMOPLAY, the MANNER of Germany etc.The disadvantage of this mode is that whole hot mouth is very big, and seal also is at high temperature to move for a long time.3, gas (oil) cylinder is placed on hot mouth on one side, and horizontal positioned, adopts gear mechanism, the rotation by bar drives needle and moves up and down.Adopt the company of this mode that Canadian MOLDMASER is arranged, the DME of the U.S., the GUNTHER of Germany etc.This structure requires very high to the part processing of hot mouth own, and user's processing is also comparatively complicated, and rotation is changed into translation, and needle is subjected to cross component force can cause that also valve needle movements is not smooth.At the hot mouth of single-point needle valve of said structure, our the present as can be seen hot mouth ubiquity of single-point needle valve processed complex, assembling is complicated and disadvantage with high costs.
The utility model content
Technical problem to be solved in the utility model is, overcome the deficiencies in the prior art, a kind of injection mold hot mouth of single-point needle valve is provided, this injection mold with the hot mouth of single-point needle valve under the prerequisite of the result of use that reaches external like product, saved the processing and manufacturing cost greatly, requirement to seal also reduces greatly, its component number is less, process simple relatively, easy to assembly, the whole system heating is average, and motion steadily, most critical be the very big reduction of manufacturing cost, very help product to promote on a large scale.
The technical scheme that its technical problem that solves the utility model adopts is: the injection mold hot mouth of single-point needle valve, comprise main nozzle, hot mouth, the needle that in the middle of hot mouth and main nozzle, slides up and down, also comprise panel and board, main nozzle and hot mouth are assembled together by shop bolt and screw and panel and board, design has cylinder or oil cylinder in the panel of hot mouth one side, design has crossbeam and guide pillar in the cavity of panel and board composition, crossbeam and guide pillar are assembled together in the mode of being solidly connected by screw, and piston and guide pillar in cylinder or the oil cylinder are assembled together in the mode of being solidly connected by lock screw; Form a cavity by main nozzle and hot mouth, crossbeam one end and the needle upper end of inserting in the described cavity are assembled together.
In technique scheme, in the cavity of board the design have a guide pin bushing, described guide pin bushing and guide pillar to be movingly mode is assembled together.
Design has a grub screw above lock screw.
On main nozzle top and the design of panel intersection one centring ring is arranged.
Design has cavity that A runner and B runner, described A runner and B runner avoid being made up of main nozzle and hot mouth, designs the two ends at described cavity in main nozzle and hot mouth.
The beneficial effects of the utility model are: 1, the injection mold of said structure with the hot mouth of single-point needle valve under the prerequisite of the result of use that reaches external like product, because it is reasonable in design, simple in structure, thereby greatly reduced its manufacturing cost, very help product and apply on a large scale.2, cylinder or oil cylinder are separated design with hot mouth, the requirement of seal is reduced greatly.3, crossbeam and guide pillar are assembled together in the mode of being solidly connected by screw, piston and guide pillar in cylinder or the oil cylinder are assembled together in the mode of being solidly connected by lock screw, design has a grub screw above lock screw, and it is stable to guarantee that it connects in moving up and down; Design has a guide pin bushing in the cavity of board, described guide pin bushing and guide pillar are movingly, and mode is assembled together, guide pillar moves up and down in guide pin bushing, can guarantee that crossbeam only does up and down translation, no any deflection up and down, thereby crossbeam is moved up and down steadily, and needle is moved up and down steadily, thereby its result of use can reach the result of use of external like product.4, because the part number of whole system is less, and processing is simple relatively, and the client assembles also very convenient in mould, and the whole system heating is average.5, main nozzle is locked with only depending on four screws being connected of hot mouth, and two hanging platforms compress with template about leaning on simultaneously, guarantee never to leak glue.
