Abstract
The utility model discloses a plastic cement mould hot sprue unit, consisting of a sprue plate, a steam cylinder, a valve needle connected with and controlled by the steam cylinder and a nozzle sleeved on the needle. A runner is arranged at the bottom of the nozzle, a diverter valve is installed on the sprue plate, a cement sealing valve is installed in the cylindrical chamber at the end of the nozzle, and the diverter valve and the cement sealing valve are sleeved on the valve needle. The diverter valve matches with the needle by distance, the cement sealing valve matches with the valve needle by hydraulic sealing sliding, and the end face of the diverter valve matches with the end face of the cement sealing valve by hydraulic sealing. A flow passage is provided on the diverter valve and the cement sealing valve for the plastic cement to flow, and the flow passage communicates with the sprue plate and the flow passage of the nozzle. In the utility model, after the hot sprue plate passes the heating coil and expands by heating, the steam cylinder can still drive the valve needle to move up and down freely, in addition, the steam cylinder, the valve needle, the nozzle and the runner can be guaranteed to be kept on the same center line, and in the mean time, the cement can be sealed fairly well.
Description
Technical field
The utility model relates to a kind of plastic mould hot flow path device, is the improvement technology of plastic mould hot flow path device specifically.
Technical background
At present, the plastic mould hot flow path device that people are seen all is to move up and down by cylinder drive needle to realize injection and sealing.In the motion process of needle, its sealing mode realizes sealing on runner plate, this sealing mode needs very little fit clearance, and runner plate expands through heating wire heating back generation, bump dead phenomenon thereby needle and runner plate occur, cause cylinder can not drive the needle action.Because of the needle akinesia, causing can not injection or can not sealing, thereby causes hot flow path device cisco unity malfunction.
Summary of the invention
The purpose of this utility model be at hot runner manifold through after heating wire adds thermal expansion, cylinder still can drive needle freely motion up and down, and guarantee cylinder, needle, nozzle, cast gate remain at same in the heart, sealing very well simultaneously.
The utility model TOP-TIP is achieved through the following technical solutions purpose of the present invention.
A kind of plastic mould hot flow path device, comprise runner plate, cylinder links to each other with cylinder and is subjected to the needle of its control, needle upper ring cap one nozzle, the bottom of nozzle is provided with cast gate, it is characterized in that: flow divider is installed on the runner plate, the sealing valve is installed in the cylindrical cavity of nozzle-end, flow divider and sealing valve collar are enclosed within on the needle, be matched in clearance between flow divider and the needle, for liquid sealing is slidingly matched, the flow divider end face is that liquid sealing cooperates with the sealing valve end face that it joins between sealing valve and the needle; Flow divider and sealing valve are provided with the runner that flows for plastic cement, and this runner communicates with runner on runner plate and the nozzle.
Runner on the described sealing valve is the circular passage.
The passage of described flow divider is provided with wedge shape sealing sheet.
Be provided with anti-adverse current lid between described cylinder and the diversion rod, anti-adverse current bezel ring, is enclosed within on the needle.
The end of described anti-adverse current lid has breach.
The utility model technology compared with prior art has the following advantages:
Carry out direct sealing because prior art adopts on needle and the runner plate, runner plate produces through heating wire heating back and expands, and needle and runner plate occur and bumps extremely, causes the needle akinesia.The utility model technology can solve this shortcoming, and its principle is that flow divider is housed on the runner plate, and needle can pass through flow divider loosely.After runner plate adds thermal expansion, produce displacement, and the flow divider on the runner plate can satisfy the displacement of runner plate, therefore can not cause and bump dead phenomenon, can realize that like this plastic cement enters mold cavity in proper order, reach good molding effect.
Description of drawings
Fig. 1 is the explosive view of the utility model plastic mould hot flow path device.
Fig. 2 is the assembly structure figure of the utility model plastic mould hot flow path device.
The specific embodiment
Below in conjunction with accompanying drawing the utility model plastic mould hot flow path device is described in further detail:
As Fig. 1 and shown in Figure 2, the top of plastic mould hot flow path device is a cylinder 7, the effect of cylinder 7 is to drive moving up and down of needle 5 to realize the effect of injection and sealing, below the cylinder 7 is anti-adverse current lid 4, anti-adverse current lid 4 plays fixation, peripheral in addition jagged be can flow away for the gas that heating produces; What contact with anti-adverse current lid 4 is runner plate 8, flow divider 3 is housed on the runner plate 8, the effect of flow divider 3 is, make its cooperation become a plastic cement passage on the runner plate 8 through being installed in, there is a step through-hole to pass through in the middle of the flow divider 3 for needle 5, step through-hole is greater than needle 5 and sealing valve 2 heads, guarantee runner plate 8 heating produce after the displacements not can and needle 5 and sealing valve 2 between bump mutually dead, and circular end surface forms plane contact in the middle of the little end surface of flow divider 3 and sealing valve 2 major parts, realize the plane sealing and prevent that plastic cement from leaking outside, sealing valve 2 is mounted in nozzle 1 stub end cylindrical, the circular passage is arranged in the middle of the sealing valve 2, its effect is to be connected with flow divider 3, form a passage, the two is an indispensable integral body for sealing valve 2 and flow divider 3, and they are to guarantee cylinder 7, needle 5, nozzle 1, cast gate 6 is at same supercentral important composition parts.The effect of nozzle 1 is a plastic cement passage, what be used with nozzle 1 is cast gate 6, cast gate 6 is the outlet of final injection moulding and the window that stops injection, this cast gate 6 realizes that injection and sealing are to lean on the piston of cylinder 7 drive needle 5 to move up and down to realize, needle 5 is to be sealed and matched with cast gate 6, be the piston of cylinder 7 cast gate 6 beginning injections then when moving upward, cast gate 6 stops injection if the piston of cylinder 7 moves downward, runner plate 8 all has heating wire to heat with nozzle 1, forming whole plastic cement flow process all has temperature to guarantee that reaching plastic cement can flow in certain temperature, renders a service thereby improve to produce, improve the quality of product, reduced the generation of waste material.
