Description

Multi-layer installation universal fixture for valve plate of injection molding machine

Technical Field

The utility model relates to an injection molding machine clamp, in particular to a multi-layer installation universal clamp for a valve plate of an injection molding machine.

Background

At present, a single-layer profiling fixture is generally directly installed on a workbench of a machining center in the process of machining a valve plate of an injection molding machine, and then the valve plate is fixed on the profiling fixture for machining.

The prior art has the following problems:

The machining of the valve plate is a very time-consuming process, and relates to multi-faceted milling surface drilling, more cross holes and multi-segment counter bores, high steel piece hardness and slower processing speed, the too few stations means that the processing efficiency is low, repeated tool changing can be continuously carried out, the working table is frequently deflected to change the surface, redundant feeding actions are carried out, and the processing efficiency of a single process is low, so that negative effects can be brought to the whole process flow. If the capacity requirement is too high, the single-layer master clamp will affect the production plan, thereby resulting in increased staff workload and increased production risk during the production process.

Disclosure of utility model

The utility model provides a multi-layer installation universal fixture for a valve plate of an injection molding machine, which is used for overcoming the defect of low machining efficiency caused by frequent clamping when a single-layer profiling fixture is used for machining the valve plate in the prior art.

In order to solve the technical problems, the utility model provides the following technical scheme:

The utility model discloses a multi-layer mounting universal fixture for a valve plate of an injection molding machine, which comprises a lower fixture, wherein the lower fixture is connected with an upper fixture through a support column, a plurality of clamping grooves are formed in the periphery of the lower fixture, limiting blocks for limiting the valve plate are arranged on the clamping grooves, and a pressing plate is used for fixing the valve plate on the lower fixture and the upper fixture through bolts.

Further, one end of the support column is fixed with the upper clamp through a screw, and the other end of the support column is fixed with the lower clamp through a screw.

Further, the support column is mounted on the lower clamp through a countersunk hole in the back of the lower clamp through a screw and is fixed on a workbench of the machining center together.

Further, the valve plate is arranged on the lower clamp through a limiting block, and the size of the limiting block is matched with the size of the valve plate and is used for positioning the valve plate.

The beneficial effects achieved by the utility model are as follows: the same double-layer profiling mold can be used for processing different valve plates, repeated disassembly and assembly are not needed, repeated work caused by recalibration of a coordinate system and repeated tool setting during tool replacement is reduced, a double-layer processing clamp can be simultaneously applied to a series of tools, and the problem that special valve plates need to be processed independently is solved, so that production efficiency is affected, and workload of staff is reduced.

Detailed Description

The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings, it being understood that the preferred embodiments described herein are for illustration and explanation of the present utility model only, and are not intended to limit the present utility model.

Example 1

As shown in fig. 1 to 3, a multi-layer installation universal fixture for a valve plate of an injection molding machine comprises a lower fixture 1, wherein the lower fixture 1 is connected with an upper fixture 3 through a support column 2, a plurality of clamping grooves 8 are formed in the periphery of the lower fixture 1, limiting blocks 5 for limiting the valve plate 4 are arranged on the clamping grooves 8, and a pressing plate 6 fixes the valve plate 4 on the lower fixture 1 and the upper fixture 3 through bolts 7.

The valve plate 4 is arranged on the lower clamp 1 through a limiting block 5, and the size of the limiting block 5 is matched with that of the valve plate 4 and is used for positioning the valve plate 4.

The support column 2 is mounted on the lower clamp 1 through a countersunk hole 9 on the back of the lower clamp 1 by screws and is fixed on a workbench of a machining center together.

One end of the support column 2 is fixed with the upper clamp 3 through a screw, and the other end is fixed with the lower clamp 1 through a screw.

Under the condition of higher requirements on the machining efficiency, the double-layer profiling clamp can improve the efficiency, and when the upper clamp 3 is not needed, the support column 2 and the upper clamp 3 are only required to be detached, so that the change of the yield requirement can be flexibly dealt with; if a new special valve plate 4 needs to be processed, a new profiling clamp is not required to be designed, the new valve plate 4 can be corresponding to the size of the valve plate by resetting the position of the limiting block 5, the design period is short, and the early-stage cost investment is low; because the same double-layer profiling clamp can be used by changing the positions of the limiting blocks 5 when different valve plates 4 are processed, repeated disassembly and assembly are not needed, and repeated coordinate alignment caused by tool replacement can be omitted.
