Description
Technical Field
The utility model belongs to the technical field of the plastic former, a head is moulded plastics to injection molding machine is related to.
Background
An injection molding machine is a main molding device for making thermoplastic plastics or thermosetting plastics into plastic products with various shapes by using a plastic molding die. The injection molding machine injects molten plastic to fill the mold cavity by applying high pressure to the molten plastic. The hot melt injection molding head of the existing injection molding machine is easy to overflow hot melt plastic from the discharge position of the injection molding head during the injection molding interval, and if the injection molding interval is long, the hot melt plastic in the injection molding head is easy to rapidly cool, so that the next injection molding process is seriously influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an injection molding machine head of moulding plastics to the above-mentioned problem that prior art exists, the utility model aims to solve the technical problem that how make the head of moulding plastics carry out better heat preservation in the interval of moulding plastics.
The purpose of the utility model can be realized by the following technical proposal: the utility model provides an injection molding machine head of moulding plastics, its characterized in that, this injection molding machine head of moulding plastics includes insulation support, takeover and discharging pipe, takeover fixed connection is in the insulation support, discharging pipe sliding connection is on the takeover, the discharging pipe can be located in the insulation support, be connected with between discharging pipe and the takeover and order about the discharging pipe to the gliding reset spring in the insulation support, the fixed end cap that is provided with the discharge gate that can insert and establish in the discharging pipe and block up the discharging pipe of takeover inner wall.
The end that the extrusion material appearance chamber of injection molding machine was connected to the takeover, hot melt plastics receive the extrusion force effect and get into in the discharging pipe by the takeover, make discharging pipe internal pressure increase, order about reset spring extension, the discharging pipe slides out the insulation cover along the takeover, and make the end cap break away from the shutoff to the discharging pipe export, hot melt plastics are discharged to the die cavity of treating moulding plastics by the discharging pipe, after single process of moulding plastics is accomplished, the extrusion pressure of injection molding machine reduces, receive reset spring's restoring force effect, the discharging pipe is retracted to in the insulation cover, meanwhile, end cap shutoff discharging pipe discharge gate, make hot melt plastics can not overflow, also make the discharging pipe be located the insulation cover, avoid its rapid cooling to lead to discharging pipe export.
In the injection molding head of the injection molding machine, the discharge pipe is externally provided with a limiting check ring, and the inner wall of the heat insulation sleeve is provided with a limiting step matched with the limiting check ring.
The maximum position that spacing step and spacing retaining ring can make the discharging pipe move outward is injectd, and the insulation cover is made for the heat preservation material, like rock wool insulating tube.
Drawings
FIG. 1 is a schematic structural diagram of an injection head of the injection molding machine.
In the figure, 1, a thermal insulation sleeve; 2. taking over a pipe; 3. a discharge pipe; 4. a return spring; 5. a plug; 6. a limit retainer ring; 7. and a limiting step.
Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in figure 1, the injection molding machine injection molding head comprises a heat insulation sleeve 1, a connecting pipe 2 and a discharging pipe 3, wherein the connecting pipe 2 is fixedly connected in the heat insulation sleeve 1, the discharging pipe 3 is slidably connected on the connecting pipe 2, the discharging pipe 3 can be located in the heat insulation sleeve 1, a reset spring 4 for driving the discharging pipe 3 to slide in the heat insulation sleeve 1 is connected between the discharging pipe 3 and the connecting pipe 2, and an end cap 5 which can be inserted into the discharging pipe 3 and blocks a discharging port of the discharging pipe 3 is fixedly arranged on the inner wall of the connecting pipe 2.
The connecting pipe 2 is connected with the tail end of an extrusion material containing cavity of the injection molding machine, hot melt plastic enters the discharging pipe 3 from the connecting pipe 2 under the action of extrusion force, the pressure in the discharging pipe 3 is increased, the reset spring 4 is driven to stretch, the discharging pipe 3 slides out of the heat insulation sleeve 1 along the connecting pipe 2, the plug 5 is separated from plugging of an outlet of the discharging pipe 3, the hot melt plastic is discharged into a mold cavity to be subjected to injection molding from the discharging pipe 3, after a single injection molding process is completed, the extrusion pressure of the injection molding machine is reduced, the discharging pipe 3 retracts into the heat insulation sleeve 1 under the action of restoring force of the reset spring 4, meanwhile, the plug 5 plugs a discharging port of the discharging pipe 3, the hot melt plastic cannot overflow, the discharging pipe 3 is also positioned in the heat insulation sleeve 1, and.
The discharging pipe 3 is externally provided with a limiting retainer ring 6, and the inner wall of the heat-insulating sleeve 1 is provided with a limiting step 7 matched with the limiting retainer ring 6. The maximum position that spacing step 7 and spacing retaining ring 6 can make discharging pipe 3 move outward is injectd, and insulation cover 1 is made for the heat preservation material, like rock wool insulating tube.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
