Description

Technical Field

[0001] This utility model relates to the field of injection molding machines, and in particular to a mounting base for assembling hoppers. Background Technology

[0002] Chinese patent CN207327537U discloses an extrusion mechanism for injection molding machines or blow molding machines, including a barrel and a three-five hopper. The bottom of the three-five hopper is provided with a mounting base that is fixedly connected to the three-five hopper. The mounting base is fixedly set on the feed port on the barrel by screws.

[0003] When installing the three-five hopper onto the barrel, a mounting surface is usually opened on the barrel, and threaded holes are set in the mounting surface for screws to be inserted to achieve the installation between the barrel and the mounting base. However, this installation method can only be used when the barrel diameter is large. If the barrel diameter is small, the size of the mounting surface will be limited, which will make it impossible to install the bottom of the hopper onto the mounting surface. At the same time, if the barrel diameter is small, the wall thickness of the barrel is not sufficient to set up the mounting surface and threaded holes. Utility Model Content

[0004] This invention addresses the limitation of existing technologies where hoppers cannot be installed on small-diameter barrels by setting up mounting planes, by providing a mounting base for hopper assembly.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method: A mounting base for assembling a hopper includes a mounting base body. The mounting base body includes a mounting half-ring and a mating half-ring that is assembled with the mounting half-ring to form a ring and clamped onto the barrel. The mounting half-ring has a mounting plane, and the mounting plane has feed through holes that respectively mate with the discharge port of the hopper and the feed port of the barrel. The mounting half-ring and the mating half-ring are clamped onto the barrel by a fixing component.

[0006] Using the above scheme, the mounting plane on the mounting half-ring allows the hopper to be installed on it, and the mounting half-ring and the mating half-ring can be clamped to the barrel by fixing components, thereby allowing the hopper to be installed on the barrel with a smaller diameter.

[0007] Preferably, both the mating half-ring and the mounting half-ring are fixed by fixing components on both sides.

[0008] Preferably, one end of the mating half-ring is hinged to the mounting half-ring, and the other end is fixed to the mounting half-ring by a fixing component.

[0009] Preferably, the fixing component includes a plurality of mounting holes correspondingly provided on the mating half ring and the mounting half ring, bolts passing through the mounting holes of the mating half ring and the mounting half ring, and nuts cooperating with the bolts to tighten the mating half ring and the mounting half ring onto the barrel.

[0010] Using the above scheme, the mounting holes on the mating half-ring and the mounting half-ring allow bolts to be inserted. After the bolts pass through the mounting holes on the mating half-ring and the mounting half-ring, the mating half-ring and the mounting half-ring can be tightened onto the outer wall of the barrel by the nuts, thereby installing the hopper onto the barrel.

[0011] Preferably, an anti-deflection component is provided between the mounting base body and the barrel to prevent the mounting base body from deflecting after it is fitted outside the barrel.

[0012] Preferably, the anti-deflection component includes a limiting post protruding from the inner wall of the mounting base body and a limiting hole provided on the outer wall of the barrel for the insertion of the limiting post.

[0013] Using the above solution, the limiting post protruding on the outer wall of the mounting base body can be inserted into the limiting hole on the outer wall of the barrel when the mounting base body is installed on the outer wall of the barrel, thereby preventing the mounting base body from deflecting on the barrel after it is installed on the outer wall of the barrel.

[0014] Preferably, the anti-deflection component includes a limiting post protruding on the outer wall of the barrel and a limiting hole recessed on the inner wall of the mounting base for the insertion of the limiting post.

[0015] By adopting the above scheme, the limiting post is set on the outer wall of the mounting base and the limiting hole is set on the inner wall of the mounting base body. This can also prevent the mounting base body from flipping on the outer wall of the barrel after it is installed on the outer wall of the barrel.

[0016] Preferably, the end of the feed through hole away from the feed inlet of the barrel is shaped like a gradually expanding frustum.

[0017] By adopting the above scheme, the end of the feed through hole away from the feed inlet of the barrel is set into a gradually expanding frustum shape. This reduces the probability of material adhering to the surface of the feed through hole when the diameter of the discharge outlet of the hopper changes, thereby improving the compatibility between the feed through hole and the hopper.

[0018] This utility model has significant technical effects due to the adoption of the above technical solutions: the mounting plane on the mounting half ring allows the hopper to be installed on it, and the mounting half ring and the mating half ring can be clamped to the barrel by the fixing components, thereby allowing the hopper to be installed on the barrel with a smaller diameter.

The mounting plane 9 is provided with feed through holes 5 that respectively connect with the discharge port of the hopper and the feed inlet 2 of the barrel 1. The end of the feed through hole 5 away from the feed inlet 2 of the barrel 1 is gradually expanding outward into a frustum shape. The mounting half-ring 301 and the mating half-ring 302 are clamped onto the barrel 1 by a fixing component.
