Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, specifically to a drilling and rotating mechanism for an ejector guide plate of an injection molding machine. Background Technology

[0002] Currently, the machining of ejector guide plates in injection molding machines involves processing three sides, which is accomplished collaboratively by a machining center and a conventional drilling machine. The machining center completes the machining of the holes and surfaces on the two main sides, while the conventional drilling machine completes the machining of the back and side holes.

[0003] The ejector guide plate needs to be machined on both the reverse and side surfaces using a standard drilling machine. However, the worktable of a standard drilling machine is just a flat surface, so machining both surfaces requires flipping the workpiece twice to complete the machining process. Furthermore, the ejector guide plate is a flat, plate-like part. Machining holes on the reverse surface is relatively stable and easy to position by placing it flat on the drilling machine's worktable. However, when machining threaded holes on the side surface, the ejector guide plate needs to be clamped vertically. Since it is a relatively thin plate-like part, standing it vertically poses a significant safety hazard and risks of tipping over. Utility Model Content

[0004] The purpose of this invention is to provide a drilling and rotating mechanism for the ejector guide plate of an injection molding machine, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drilling and rotating mechanism for an ejector guide plate of an injection molding machine, comprising a base, a worktable support body fixedly mounted on the base, a rotating shaft rotatably connected between the worktable supports, a worktable fixedly mounted on the rotating shaft, a worm gear fixedly mounted at one end of the rotating shaft, a fixed seat fixedly mounted on the worktable support body corresponding to the worm gear, a worm rotatably connected to the fixed seat, the worm rotatably connected to the worm gear, a handwheel fixedly mounted on one side of the worm, an ejector guide plate fixedly mounted on the worktable, and a positioning pin inserted into the worktable support body.

[0006] Preferably, the worktable is provided with positioning holes corresponding to the positioning pins.

[0007] Preferably, the ejector guide plate is connected to the worktable via a pull pin positioning pin. The pull pin positioning pin has a stepped two-section structure, with a positioning pin on the upper part and a threaded post on the lower part.

[0008] Preferably, there are two positioning pins, one for the horizontal position of the worktable and the other for the vertical position of the worktable.

[0009] Compared with the prior art, the beneficial effects of this utility model are: the conversion of the drilling angle of the ejector guide plate can be realized through a simple worm gear transmission device, avoiding the risk of tipping and injury caused by manual handling; reducing the original two clamping operations to one clamping operation can improve production efficiency; the indexing pin ensures the positioning angle and guarantees the verticality of the drilling, thus improving the processing quality of the ejector guide plate.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0013] Please refer to 1-2. One embodiment of this utility model provides: a drilling and rotating mechanism for an ejector guide plate of an injection molding machine, including a base 1, a worktable support 2 fixedly mounted on the base 1, a rotating shaft 3 rotatably connected between the worktable supports 2, a worktable 4 fixedly mounted on the rotating shaft 3, a worm gear 5 fixedly mounted at one end of the rotating shaft 3, a fixed seat 6 fixedly mounted on the worktable support 2 corresponding to the worm gear 5, a worm 7 rotatably connected to the fixed seat 6, the worm 7 rotatably connected to the worm gear 5, a handwheel 8 fixedly mounted on one side of the worm 7, an ejector guide plate 9 fixedly mounted on the worktable 4, and a rotating shaft 3 rotatably connected to the worktable support 2. Insert the positioning pin 10, turn the handwheel 8 to make the worktable 4 horizontal. Use the positioning pin 10 to pass through the worktable support 2 and insert it into the corresponding horizontal fixing hole of the worktable 4 to fix the ejector guide plate 9 on the worktable 4. Perform the ejector guide plate 9 and reverse operation processing. After the operation is completed, take out the positioning pin 10, turn the handwheel 8 to make the worktable 4 vertical. Use the positioning pin 10 to pass through the worktable support 2 and insert it into the corresponding vertical fixing hole of the worktable 4 to complete the vertical position fixation of the worktable 4. Then perform the operation on the ejector guide plate 9.

[0014] The worktable 4 is provided with positioning holes corresponding to the positioning pins 10. The worktable 4 is fixed in both horizontal and vertical states by using the corresponding positioning holes.

[0015] The ejector guide plate 9 is connected to the worktable 4 by a rivet positioning pin. The rivet positioning pin has a stepped two-section structure, with a positioning pin on the top and a threaded post on the bottom. The ejector guide plate 9 is fixed by the rivet positioning pin, and the threaded post is connected to the bottom by a nut to fix the ejector guide plate 9.

[0016] There are two positioning pins 10, one for the horizontal position of the worktable 4 and the other for the vertical position of the worktable 4, which facilitates the adjustment of the working state of the worktable 4.

[0017] Working principle: In use, firstly, by rotating the handwheel 8, the worm gear 7 is rotated, which in turn drives the worm wheel 5 to rotate. The worm wheel 5 then drives the rotating shaft 3 to rotate, thereby rotating the worktable 4. Once the worktable 4 is in a horizontal position, the positioning pin 10 is inserted through the worktable support body 2 and into the corresponding horizontal fixing hole of the worktable 4 to fix the worktable 4 in a horizontal position. Then, the ejector guide plate 9 is fixed to the worktable 4 using the pull pin positioning pin, and the holes on the ejector guide plate 9 are machined. After the horizontal position is completed, the positioning pin 10 is removed, and the handwheel 8 is rotated to rotate the worktable 4 until it reaches a vertical position. Then, the positioning pin 10 is inserted through the worktable support body 2 and into the corresponding vertical fixing hole of the worktable 4 to fix the worktable 4 in a vertical position, and the holes on the ejector guide plate 9 are machined.
