Description

Technical Field

[0001] The utility model relates to the technical field of decorative ring moulds, and more specifically, to a decorative ring mould for a rear door of an automobile. Background Art

[0002] When a car is purchased, there are no decorative items on the rear door. People usually buy decorative rings for the rear doors online. Such decorative rings are usually made of a mold, which consists of a movable mold and a fixed mold. The movable mold is installed on a movable template of an injection molding machine, and the fixed mold is installed on a fixed template of the injection molding machine. During injection molding, the movable mold and the fixed mold are closed to form a casting system and a cavity. For example, a mold for a decorative ring for a rear door of a car described in prior art publication number (CN207901555U) is connected to a slide rod and a slide groove through a slide rod, so that the vertical rod drives the slide rod to slide in the slide groove, and at the same time, the vertical rod enters the rectangular groove, and the inner wall of the rectangular groove squeezes the baffle rod to drive the rotating shaft to rotate on the vertical rod. The baffle rod pushes the convex rod to squeeze the spring, so that the baffle rod can move in the direction of the vertical rod. When the baffle rod passes through the rectangular groove, the spring resets and bounces the baffle rod.

[0003] When the above device is in use, its structure is relatively complex, it is easy to be damaged, and it is inconvenient to repair, which affects the production efficiency of the automobile rear door decorative ring. In addition, the mass of the movable mold is relatively large. When the movable mold and the fixed mold are closed, the movable mold will fall quickly and is relatively unstable. Long-term use can easily cause damage to the surface of the fixed mold, thereby affecting the production quality of the automobile rear door decorative ring. Utility Model Content

[0004] In order to overcome the above defects of the prior art, the utility model provides a rear door decorative ring mold for an automobile. The technical problem to be solved by the utility model is: how to increase the closing stability of the rear door decorative ring mold for an automobile.

[0010] The outer end surfaces of the mold supporting bottom plate, the bottom supporting block and the top supporting block in a top-view direction are arranged in a coplanar state.

[0011] In a preferred embodiment, the outer end surfaces of the bottom mold and the top mold in a top view are arranged in a coplanar state;

[0012] There are a plurality of limit sliding bars, which are arranged in an array on both sides of the vertical central axis in the top view direction of the mold support bottom plate.

[0013] In a preferred embodiment, the outer end surface of the limiting sliding rod is matched with the inner end surface of the circular matching hole;

[0014] There are multiple support springs, which are arranged in an array on both sides of the vertical center axis of the mold support base plate in the top view direction. The height of the support spring in the main view direction is greater than the height of the support base block in the main view direction.

[0015] In a preferred embodiment, the damping telescopic rod, the shock absorbing base and the support pad are provided in plural numbers and are arranged in an array state on both sides of the transverse central axis in the top view direction of the mold support bottom plate;

[0016] The damping telescopic rod passes through the interior of the limiting groove, and a gap is reserved between the outer end surface of the damping telescopic rod in the top view direction and the inner end surface of the limiting groove.

[0017] Technical effects and advantages of the utility model:

[0018] When the utility model is actually used, the corresponding setting state of the supporting bottom block and the supporting spring can prevent the bottom mold from falling at a fast speed, thereby avoiding damage to the bottom mold. At the same time, the corresponding setting state of the limit groove and the circular adapter hole can effectively increase the installation stability and docking accuracy of the bottom mold and the top mold. At the same time, the corresponding setting state of the damping telescopic rod, the shock-absorbing base and the support pad can effectively reduce the descending speed of the top mold, avoid damage to the contact surface of the top mold and the bottom mold, thereby increasing the stability of the closing of the automobile rear door decorative ring mold.
