Description

Technical Field

[0001] The utility model relates to a fixing fixture, in particular to a combined fixing fixture used for assembling a shutoff nozzle of an injection molding machine. Background Art

[0002] The shutoff nozzle of the injection molding machine is a device used to control drool and filaments during the injection molding process of the injection molding machine. Since the main components and some components of the control cylinder are small in size and mostly cylindrical in shape, certain technical requirements are required to fix the parts during assembly. In the early assembly process of the shutoff nozzle, the piston rod, front cover, control cylinder body, main components, etc. were clamped and fixed by vise. There are some problems with this operation: 1. Each time you assemble, you need to unscrew it to change the position or replace the parts, and then tighten the vise to clamp and fix it before proceeding to the next step. Each time you replace a part, you have to repeat the operation, wasting a lot of time and manpower. 2. When tightening the vise, it may be over-clamped, causing damage to some parts. 3. The position of the vise cannot be moved, and each assembly must be moved to a fixed position, which is very inconvenient. 4. Improper operation or failure to clamp the parts during assembly will cause the parts to fall, causing personal injury and product loss. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a combined fixing fixture for assembling a shutoff nozzle of an injection molding machine with fast assembly speed and high safety performance, and various components used in assembling the shutoff nozzle are fixed on one fixture in a combined form.

[0004] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a combined fixing fixture for assembling a shutoff nozzle of an injection molding machine, comprising a fixed base plate and a first fixture seat, a second fixture seat, a third fixture seat and a fourth fixture seat respectively fixedly arranged on the fixed base plate, a first fixture hole for placing a piston rod being vertically arranged in the first fixture seat, a first fixing mechanism for fixing the end of the piston rod being fixedly arranged in the first fixture hole, a second fixture hole being vertically arranged in the second fixture seat, a second fixing mechanism for fixing the front end cover being fixedly arranged on the top of the second fixture seat, a third fixture hole for fixing an inverted control cylinder body being vertically arranged inside the third fixture seat, a fourth fixture hole for horizontally fixing and placing a shutoff nozzle body being horizontally opened on the fourth fixture seat, and a locking mechanism for locking the shutoff nozzle body being arranged on the fourth fixture seat.

[0005] The first fixing mechanism comprises a first fixing rod which is transversely fixedly arranged in the first clamp hole, and the first fixing rod is used for being plugged and fixed in cooperation with the end groove of the piston rod.

[0006] The second fixing mechanism includes at least three positioning posts, which are fixedly arranged upward on the top of the second fixture seat and evenly distributed around the circumference of the second fixture hole, and at least three positioning posts correspond to the positions of the three bolt holes on the front end cover. Since the front end cover is relatively thin, this structure is used to fix the front end cover, and the front end cover does not need to be clamped, so as to prevent the front end cover from being damaged during clamping; after the position of the front end cover is fixed, the assembly operation of the parts on the front end cover can be started.

[0007] The locking mechanism comprises a locking screw hole and a locking screw. The locking screw hole is arranged on a side hole wall of the fourth fixture hole from inside to outside. The locking screw is threadedly arranged in the locking screw hole and is used to lock the shut-off nozzle body.

[0008] Compared with the prior art, the utility model has the advantage that when in use, the piston rod can be fixed by only fixing it on the first clamp seat, so that the fixed piston is installed on the piston rod; the control cylinder body is placed upside down in the third clamp hole of the third clamp seat and fixed with the rear cover facing upward, and the water pipe joint can be installed on the rear cover; the fourth clamp seat locks and fixes the shut-off nozzle body laterally, and the front nozzle head and the rear piston part of the shut-off nozzle body can be tightened in turn, eliminating the steps and time of changing positions; the entire fixing fixture adopts a combined form to simultaneously fix various components used in the assembly of the shut-off nozzle on one fixture, thereby greatly improving the assembly speed, and having higher safety performance, effectively reducing product waste and loss, and preventing product damage, falling, etc. BRIEF DESCRIPTION OF THE DRAWINGS
