Description
Technical field
The utility model relates to the TOP-TIP for injection moulding, and espespecially a kind of laminated mould connects adhesive dispenser.
Background technology
At present, along with plastic cement raw material, cost of labor rise in price, enhancing productivity is the problem that each plastics production producer primarily solves.The production of plastic cement products be unable to do without template, template also continuous renewal, to adapt to market competition.Die cavity as plastic template goes out one by before, and one goes out to develop into one and goes out 100 two to today, greatly improves production efficiency.But one goes out multi-cavity is applicable to some miscellaneous goods, centering, large product cannot accomplish multi-cavity by the restriction such as injection machine, template, and even mould two chamber all cannot realize, and television cabin and bonnet are exactly this situation.For this reason a kind of novel and efficient new technique---laminated mould technology solves the conversion of plane to solid space of existing template, it can not only be applied on miscellaneous goods can the lamination of implementation space, centering large product can realize a multi-cavity mold equally, such as TV set front frame, bonnet etc.
Laminated mould has two or more die joint, and runner is long, and runner needs to overlap at different die joint.Therefore laminated mould must need hot flow path to coordinate.Because laminated mould has multiple die joint, when die sinking pickup, TOP-TIP must have at least a face separately, and this becomes make the originally overall sealing of hot flow path into two or more independent sealing area.When next mould injection moulding, two or more hot flow path sealing area will become overall region again.In mold-closing injection and this circulation of die sinking pickup, how to design die sinking sealing, matched moulds leads to one of key technology that glue is hot flow path design, existingly realize laminated mould die sinking sealing, the adhesive dispenser that connects that matched moulds leads to glue exists the deficiency not catching up with actual needs in quality, the requirement of laminated mould can not be met.
Summary of the invention
The utility model need the technology solved to ask to be to overcome existingly realize laminated mould die sinking sealing, there is the deficiency not catching up with actual needs in the adhesive dispenser that connects that matched moulds leads to glue, provide a kind of laminated mould to connect adhesive dispenser in quality.
A kind of laminated mould of the utility model connects adhesive dispenser and adopts following technical proposals:
A kind of laminated mould connects adhesive dispenser, comprises main nozzle, sealing insert and envelope pin, and main nozzle, sealing insert and envelope pin are respectively split up into two unit, and two unit lay respectively in the template of die joint both sides; Die joint two unit of template sealing insert and envelope pin achieve a butt joint; Be positioned at die joint be fixedly mounted with the sealing insert on side template and main nozzle and form sizing material passage, the main nozzle of two unit is achieved a butt joint at die joint by sealing insert; Be positioned at die joint to be formed with envelope pin hole sealing insert being opened system with the envelope pin on side template and insert shutoff or extract coordinating of logical glue.
Technique scheme is further elaborated:
Envelope pin and the respective piston of each unit are equipped with, and each piston and respective cylinder are equipped with and drive.
Respective cylinder is installed on its air cylinder base.
Envelope pin is also equipped with guide rail right separately, and envelope pin moves along guide rail, guarantees and the envelope pin hole precise match in sealing insert.
In main nozzle periphery, sheathed heating circle, causes the sizing material in main nozzle to be in molten condition.
Working mechanism of the present utility model is: during matched moulds, the envelope pin of two unit, the sealing insert being shaped with envelope pin hole and main nozzle close up docking, the cylinder of each unit controls to close the sizing material access sites that each unit envelope pin is extracted out corresponding sealing insert envelope pin hole by plug, the sizing material passage of main nozzle is switched on by sealing insert, can injecting glue.Before die sinking, the cylinder of each unit controls to close the envelope pin hole that corresponding sealing insert is entered in the cushion of each unit envelope by plug, and the sizing material passage of main nozzle is blocked by sealing insert, then carries out die sinking, avoids sizing material to salivate.
The beneficial effects of the utility model are:
One, solves laminated mould in die sinking process, and sealing insert, envelope pin and main nozzle, together with template movement and the problem connecing glue, achieve die sinking sealing and matched moulds leads to glue.
Its two, structure is simple, is convenient to implement, and is suitable for applying on laminated mould, is beneficial to the popularization of laminated mould, to reduce the cost of injecting products.
Its three, the utility model is used for laminated mould, a multi-cavity mold, and can injection moulding large product.

Detailed description of the invention
Below, by reference to the accompanying drawings, detailed description of the invention of the present utility model is introduced.
As shown in Figure 1 to Figure 3, a kind of laminated mould connects adhesive dispenser, comprise main nozzle, sealing insert and envelope pin, main nozzle, sealing insert and envelope pin are respectively split up into two unit: the main nozzle of first module 11 and the main nozzle 21 of second unit, first module sealing insert 12 and second unit sealing insert 22, first module envelope pin 13 and second unit envelope pin 23.Two unit lay respectively in the template 31 and 32 of die joint 33 both sides, and first module sealing insert 12 and second unit sealing insert 22 and first module envelope pin 13 and second unit envelope pin 23 achieve a butt joint at the die joint of template 31 and 32; Be positioned at die joint 33 be fixedly mounted with the sealing insert on side template and main nozzle and form sizing material passage, the main nozzle 11 and 21 of two unit is achieved a butt joint at die joint 33 by sealing insert 12 and 22; Be positioned at die joint 33 to be formed with envelope pin hole sealing insert being opened system with the envelope pin on side template and insert shutoff or extract coordinating of logical glue, insert shutoff (shown in Fig. 2) by main for first module nozzle 11 and the shutoff respectively of the main nozzle 21 of second unit, sizing material can not circulate, and also can not outwards salivate.Extracting logical glue (shown in Fig. 1) causes the main nozzle of first module 11 and the main nozzle 21 of second unit to be communicated with by sealing insert, realizes logical glue injection moulding.
Envelope pin 13 and 23 and the respective piston 14 and 24 of each unit are equipped with, and each piston 13 and 23 and respective cylinder 15 and 25 are equipped with and drive.
Respective cylinder 15 and 25 is installed on its air cylinder base 16 and 26.
Envelope pin 13 and 23 is also equipped with guide rail right separately, and envelope pin 13 and 23 moves along guide rail, guarantees and the envelope pin hole precise match in sealing insert 12 and 23.
At the sheathed heating circle 34 in main nozzle 11 and 21 periphery, the sizing material in main nozzle is caused to be in molten condition.
During matched moulds, the envelope pin 13 and 23 of two unit, the sealing insert 12 and 22 being shaped with envelope pin hole and main nozzle 11 and 21 close up docking, the cylinder 15 and 25 of each unit controls to close the sizing material access sites that each unit envelope pin 13 and 23 is extracted out corresponding sealing insert envelope pin hole by plug 14 and 24, the sizing material passage of main nozzle is switched on by sealing insert, can injecting glue.Before die sinking, the cylinder 15 and 25 of each unit controls to close the envelope pin hole that each unit envelope pin 13 and 23 is injected corresponding sealing insert 12 and 22 by plug 14 and 24, and the sizing material passage of main nozzle is blocked by sealing insert, then carries out die sinking, avoids sizing material to salivate.
The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, every above embodiment is done according to technical spirit of the present utility model any amendment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
