Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of molds, in particular to a mold for reducing the parting difference of a vehicle-mounted HUD rotating shaft. Background Art
[0002] The rotating shafts on both sides of the vehicle-mounted HUD (plastic product) have high dimensional accuracy, and the diameter tolerance is usually controlled within ±0.02mm. When making conventional plastic molds, the parting line is often set at the center of the rotating shaft due to parting requirements. At this time, the mold cavity state of the rotating shaft is half movable mold and half fixed mold.
[0003] Due to the deviation in cavity processing and polishing error, the half of the shaft cavity of the movable mold and the fixed mold will inevitably have a gap after precise matching. The range of this gap is usually within 0.05mm. Once the injection molded product fails to meet the HUD shaft accuracy requirements, it needs to be processed and corrected again, or even the movable and fixed mold steel needs to be re-invested and reprocessed, which not only increases the investment cost, but also greatly delays the mold delivery time. Utility Model Content
[0004] The utility model aims to solve the shortcomings in the prior art and proposes a mold for reducing the parting difference of a vehicle-mounted HUD shaft.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A mold for reducing the parting difference of a vehicle-mounted HUD shaft comprises a mold body and a HUD mold frame, wherein the HUD mold frame is arranged inside the mold body, an installation groove is opened on an inner wall of one side of the mold body, a mounting frame is arranged inside the installation groove, and the interior of the mounting frame is connected to a fixed mold insert and a movable mold insert through a fixing component.
[0007] As a further solution of the utility model, the fixing assembly includes two fixing screws and two threaded holes, the two threaded holes are respectively opened at one end of the fixed mold insert and the movable mold insert, and one end of the fixing screw passes through the mounting frame and is threadedly connected to the threaded hole.
[0008] As a further solution of the utility model, two mounting holes are provided on one side of the mold body.
[0009] As a further solution of the utility model, a rubber ring is fixedly connected to one side of the mold body.
[0010] As a further solution of the utility model, avoidance grooves are provided at both upper and lower ends of the mounting frame.
[0011] As a further solution of the utility model, the fixing assembly includes two sockets, two threaded rings and two plug posts. The two sockets are respectively opened at one end of the fixed mold insert and the movable mold insert, and the sockets are plugged into the plug posts. The two threaded rings are respectively threadedly connected to the upper and lower ends of the mounting frame, and the top ends of the two plug posts are fixedly connected to a frustum, and the top end of the frustum is fixedly connected to a fixing seat.
[0012] As a further solution of the utility model, a rubber pad is fixedly connected to the top end of the truncated table.
[0013] The beneficial effects of the utility model are:
[0014] 1. Through the coordinated use of the movable mold insert, the fixed mold insert, the mounting frame and the fixing screws, the movable mold insert and the fixed mold insert are installed into the mounting frame, and the fixing screws are tightened into the threaded holes to tightly combine the two inserts, so that the roughly processed half of the shaft cavity of the two inserts are combined into a complete shaft cavity. The two inserts are removed and installed in each automatic mold and the fixed mold. By using the precise positioning of the movable mold and the fixed mold, the step difference of the shaft cavity can be easily controlled within the required tolerance range, thereby improving the processing accuracy of the mold.
[0015] 2. Through the setting of the avoidance groove, when the fixing screw is rotated into the threaded hole, the top of the fixing screw will enter the avoidance groove. When the fixing screw is completely screwed into the threaded hole to fix the two inserts, the upper surface of the fixing screw is flush with the mounting frame, so that the fixing screw will not form a bulge on the mounting frame, thereby improving the surface flatness of the device.
[0016] 3. Through the setting of the rubber pad, the rubber pad has a certain deformation ability. When the threaded ring is screwed into the mounting frame to fix the round table, the rubber pad makes the joint surface of the two more substantial, avoiding the two from not being able to contact and generating a gap, thereby improving the use effect of the device.
