Injection molding extrusion head screw
The utility model relates to the technical field of machinery, specifically be an extrusion head screw rod moulds plastics.
Injection molding is a method for producing and molding industrial products. The products are generally produced by rubber injection molding and plastic injection molding. The injection molding can be classified into injection molding and die casting. An injection molding machine (injection machine or injection molding machine for short) is a main molding device for manufacturing thermoplastic plastics or thermosetting materials into plastic products with various shapes by utilizing a plastic molding die, the injection molding is realized by the injection molding machine and the die, but in the production process of a screw rod, because the hardness of the material of the screw rod is higher, the processing of the screw rod is relatively difficult when the screw rod is processed and molded, and an injection molding extrusion head screw rod is provided.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an extrude first screw rod moulds plastics to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an extrusion head screw rod moulds plastics, includes the device casing, there is the screw rod the inner chamber left side of device casing through the fixed grafting of bearing, the inner chamber of screw rod is opened there is the grafting chamber, the inside in grafting chamber is pegged graft through connecting thread and is had the stiffener, the right-hand member fixedly connected with spliced pole of stiffener, the fixed coupling in outside of spliced pole has rolling bearing, the lower extreme passes through connecting block fixed connection downside on the inner chamber right side of device casing on rolling bearing's the outside, it has the discharge gate to open on the inner chamber right side of device casing, the right-hand member fixedly connected with threaded connection ring of discharge gate, open at the right-hand member middle part of spliced pole.
Preferably, the outer side of the screw is provided with a first thread.
Preferably, the right side of the inner cavity of the insertion cavity is provided with a connecting thread.
Preferably, the threaded connection ring is provided with a second thread on the outer side.
Preferably, the first thread and the connecting thread have opposite thread directions.
Compared with the prior art, the beneficial effects of the utility model are that: this first screw rod is extruded in moulding plastics, through the structure that is equipped with the stiffener, can make the material of screw rod softer relatively to make the processing requirement of screw rod will be lower relatively, thereby great reduction the processing cost of screw rod.
Fig. 1 is a sectional view of the present invention.
In the figure: the device comprises a device shell 1, a screw rod 2, a first thread 3, a plug-in cavity 4, a reinforcing rod 5, a connecting column 6, a hexagonal groove 7, a rotating bearing 8, a discharge port 9 and a thread connecting ring 10.
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: the utility model provides an extrude first screw rod of moulding plastics, includes device casing 1, it has screw rod 2 to install the fixed grafting of inner chamber left side of casing 1 through the bearing, and screw rod 2 can adopt the softer material processing of relative stereoplasm to form, and will be lower relatively to screw rod 2's processing requirement like this to great reduction screw rod 2's processing cost, the outside of screw rod 2 is equipped with first screw thread 3. The screw thread direction of first screw thread 3 and connecting thread is opposite, the inner chamber of screw rod 2 is opened has grafting chamber 4, and grafting chamber 4 is for grafting stiffener 5, the inner chamber right side of grafting chamber 4 is opened has connecting thread. The utility model discloses a device for extruding the material, including device casing 1, spliced pole 5, connecting piece 6, rolling bearing 8, connecting block fixed connection downside on the inner chamber right side of device casing 1 is passed through to the lower extreme on the outside of rolling bearing 8, the right-hand member fixedly connected with spliced pole 6 of stiffener 5, the outside of spliced pole 6 is fixed to have cup jointed rolling bearing 8, the lower extreme passes through connecting block fixed connection downside on the inner chamber right side of device casing 1 on the outside of rolling bearing 8, the inner chamber right side of device casing 1 is opened there is discharge gate 9, and discharge gate 9 is for extruding the export of material, the right-hand member fixedly connected with threaded connection ring 10 of discharge gate 9, threaded connection ring 10 are for connecting different discharge heads to can extrude different shape material, open in the outside of. The middle part of the right end of the connecting column 6 is provided with an inner hexagonal groove 7.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
