Problems solved by technology

From a technological point of view, the functions of the injection molding machine are divided into preparation operation items and automatic circulation process functions. Among them, automatic mold adjustment is a preparation function during injection molding, and its goal is to complete the adjustment of the clamping force; if the clamping force is insufficient, It will cause the mold to leave the seam and overflow, but if it is too large, it will deform the mold, shorten the service life, and cause internal stress and unnecessary energy consumption of plastic products
[0003] The mold adjustment mechanism of the current hydraulic injection molding machine, the hydraulic motor control mold adjustment sensitivity is low, the mold adjustment method is complicated, the mold adjustme...

Embodiment 1

[0025] Embodiment 1: A quick mold adjustment method for an injection molding machine,

[0026] Such as figure 1 As shown, the quick mold adjustment method of injection molding machine of the present invention comprises the following steps:

[0027] Pre-set the clamping force according to the actual situation of the injection molding machine;

[0028] Calculate the required specified position according to the relationship between the preset clamping force and the elastic deformation of the mold;

[0029] Control the brake template to move to the specified position;

[0030] Judging whether the movable template and the mold are in contact with the mold after the preset mold confirmation time, if there is contact, go to the next step; if not, continue to move the movable template to the pre-designated position;

[0031] Open the mold, turn the mold adjustment gear, and adjust the pull rod to advance and retreat to achieve fine adjustment of the distance between the template an...

Embodiment 2

[0034] Embodiment 2: A quick mold adjustment device for an injection molding machine,

[0035] Such as figure 2 and image 3 As shown, the quick mold adjustment device of the injection molding machine of the present invention can quickly adjust the mold according to the quick mold adjustment method of the injection molding machine in the first embodiment. The mold adjustment device includes a mold adjustment motor, a large gear 100 , an encoder 200 , four mold adjustment gears 300 , a tail plate 400 , a mold adjustment screw nut 500 , a tie rod 600 and a movable template 700 . Wherein the big gear 100 and the mold-adjusting motor rotate synchronously through the belt, and the encoder 200 is electrically connected to the big gear 100. When the big gear 100 rotates, the encoder 200 starts to count; the mold-adjusting screw nut is installed on the tail plate 400, four A mode-adjusting gear 300 meshes with the large gear 100, and is arranged in a square shape on the periphery o...

Abstract

The invention relates to a rapid mold adjusting method for an injection molding machine. The method includes the following steps that S1, a moving mold plate is controlled to move to a predetermined position; whether the moving mold plate makes contact with a mold or not is judged, and if yes, the next step is performed; otherwise, the moving mold plate is continued to move to the predetermined position; S2, the mold is opened, a mold adjusting gear wheel rotates, and a pulling rod is adjusted to move forwards or backwards, so that the fine adjustment of the distance between the moving mold plate and the mold is achieved; S3, the moving mold plate is finely adjusted to reach the preset mold locking force, and the mold adjusting is successful; and if the mold locking force does not reach or exceeds the preset value, the step S2 is continued. The invention further relates to a rapid mold adjusting device for the injection molding machine. By means of the rapid mold adjusting method and the mold adjusting device for the injection molding machine, the time of the whole mold adjusting process is greatly shortened, and the working efficiency of the injection molding machining is improved.

Description

Technical field: [0001] The invention relates to the field of injection molding machines, in particular to a quick mold adjustment method for an injection molding machine and a mold adjustment device thereof. Background technique: [0002] With the continuous development of injection molding industry automation, there are more and more functional requirements for injection molding machines in the market. From a technological point of view, the functions of the injection molding machine are divided into preparation operation items and automatic circulation process functions. Among them, automatic mold adjustment is a preparation function during injection molding, and its goal is to complete the adjustment of the clamping force; if the clamping force is insufficient, It will cause the mold to leave the seam and overflow, but if it is too large, it will deform the mold, shorten the service life, and cause internal stress and unnecessary energy consumption of plastic products. ...
