Description

An installation method of a split type in-mold tapping machine

technical field

The invention relates to an installation method, in particular to an installation method of a split type in-mold tapping machine.

Background technique

Due to the needs of the overall processing and transmission structure of the existing integral push-in mold tapping machine, the relative position between the tapping hole and the positioning hole is relatively far. However, the existing processing equipment has a certain position deviation due to the influence of many factors such as processing accuracy and the use of foreigners. The accumulation of the above-mentioned position deviation will cause the tapping hole of the integral tapping machine to be misaligned with the actual tapping position offset, and because the integral in-mold tapping machine for the punch of the slider stroke (less than 60MM, greater than 250MM) in The installation is more troublesome, and the installation accuracy is extremely high, so that the existing integrated format in-mold tapping machine is likely to be inconsistent with the actual required data after the installation is completed, and the installation needs to be re-adjusted.

There are two main installation methods of the existing integrated in-mold tapping machine.

Method 1: Screw fixing seat, in-mold tapping machine, and drive cup nut are installed on the upper mold base, lifting plate, and lower mold base at the same time;

Method 2: First install the in-mold tapping machine and drive nut on the lifting plate and the lower die base, then rotate the drive screw fixing seat to the upper die base and lock it with screws.

Both of the above two installation methods have certain deficiencies. Specifically, when using the first method, when the stroke of the slider of the punch press is too small or too large, it is difficult for the above methods to ensure that the position of the three is consistent with the position on the mold. Turning the transmission screw will result in the change of the set data; if use mode 2, when used on a small-stroke punching machine, due to limited space, there is not enough space for the locking screw.

To sum up, since the machine is integral, there are certain installation limitations on the stroke of the punch. The location of the positioning hole and the tapping hole is far away, which is prone to common processing problems. When the installation positioning hole is offset, it will cause a larger deviation in the front tapping hole. The existing installation method of the integral push-in-mold tapping machine Can not meet the needs of actual production and use.

Contents of the invention

The object of the present invention is to provide an installation method of split type in-mold tapping machine with high accuracy, small error and easy operation after installation.

In order to achieve the above object, the technical solution adopted in the present invention is: a method for installing a split type in-mold tapping machine, comprising the following steps:

Step 1: First select a suitable position in the mold according to the position of the threaded hole to be tapped, add a designed lift plate to install the split type in-mold tapping machine, and divide the in-mold tapping machine into a driving part and a tapping part;

Step 2: First design the mounting pins and screws for the first chute used with the driving part on the lifting plate according to the shape and installation data of the split type in-mold tapping machine, and the pad fixing screws used with the driving part ;

Step 3: Set positioning pins on the lifting plate based on the tapping hole;

Step 4: Install the second chute on the buoyancy plate through the matching backing plate and matching positioning pin;

Step 5: Check whether the size of the first chute is suitable for the driving part, push the driving part into the first chute, and ensure that the installation hole of the driving part matches the positioning pin on the lifting plate;

Step 6: Match the contour screw on the threaded hole on the side of the first chute 1, lock the stop plate to the contour screw, and tighten the driving part with the adjustment wrench on the contour screw to ensure the The positioning hole and the positioning hole on the buoyant plate are in a tight state;

Step 7: Install and fix the second chute on the lifting plate through the matching backing plate and the matching positioning pin, and confirm that the external dimensions of the second chute match the external dimensions of the tapping part, After the confirmation is completed, push the tapping part into the second chute from the side to ensure that the positioning hole of the tapping part matches the pin alignment of the lifting plate;

Step 8: Lock the tapping part from the side through the limit meson to tighten the tapping part to the lifting plate and install the pin;

Step 9: Rivet the tapped part to the buoyancy plate through the existing pin hole of the tapped part with a pin, and fix it to the backing plate through screw locking in the vertical direction.

The present invention divides the integral in-mold tapping machine into two parts for installation and combination, narrows the far positioning pins to the periphery of the tapping hole, reduces the machining accuracy error, and then installs the tapping part using pin positioning and slipping The groove form is pushed in, which reduces the difficulty of installation.
