Description

The center of gravity adjusting device of the movable die wall of ejaculator

Technical field

The utility model relates to the center of gravity adjusting device of the movable die wall of a kind of ejaculator, more particularly, relate to and a kind ofly make movable die wall make level and both sides are just adjusted, make the center of gravity of the movable die wall that is equipped with bulky and heavy mould deflection can not take place, and avoid slide bar and lining impaired and effectively increase the center of gravity adjusting device in service life whereby.

Background technology

As shown in Figure 5, a kind of plastic injection machine 2 that is widely used is that board 21 is provided with raw material heater 22, raw material is injected into after being heated melting does ejection formation processing in the mould 23.Wherein, mould 23 is made up of feature die; and be fixedly installed on the movable die wall 24 and the fixing inner face corresponding position of die wall 25 respectively; and promote movable die wall 24 by the clamping apparatus of forming by toggle before the die holder 26 of back or oil cylinder 27; it is moved, with die sinking or the locked mode that reaches mould 23 on four slide bars 28.

From said structure as can be known, the slidably reciprocating of movable die wall 24 that is promoted by clamping apparatus 27 relies on four slide bars 28 fully, and the two ends of slide bar 28 are installed in fixedly between die wall 25 and the back die holder 26, is hanging shape.And movable die wall 24 itself just weighs several tons, add the load of mould 23 and clamping apparatus 27, be easy to cause centre-of gravity shift, especially when adding the mould 23 of various different sizes, more can make a side that is equiped with mould 23 slightly sagging, thereby make its built-in lining 241 and the center line of slide bar 28 produce skew, and produce unusual contact and wear away, as shown in Figure 6, lose due precision very soon, have a strong impact on the running that adds man-hour.

For this reason, extremely shown in Figure 9 as Fig. 7, group is provided with an adjusting device 29 at the two ends, bottom of movable die wall 24, this adjusting device 29 is used for the levelness of adjustment activity die wall 24 left and right directions, this adjusting device 29 is fixedlyed connected with the bottom of movable die wall 24 by fixing skewback 291, fixedly skewback 291 overlaps with movable skewback 292 again, and regulate by a bolt 293, the adjustment of displacement before and after making movable skewback 292 and fixedly skewback 291 can producing, and adjust whereby and make movable die wall 24 establish the bottom surface that the one side of mould 23 can cooperation activity skewback 292 to make required level and just adjust with contacting of board 21 guide rails 211 in group, make movable die wall 24 can not make the axle center of inner liner 241 produce skew because of the weight of mould 23, reduce the unusual loss that contacts and cause of lining 241 and slide bar 28, can effectively increase service life.

This adjusting device 29 is the adjustment that utilize two corresponding inclined-plane fitted bolts 293, adjust the horizontal high and low position of whole movable die wall 24 left and right directions, but can't do the adjustment of fore-and-aft direction level height simultaneously, therefore still can cause slip between lining 241 in the movable die wall 24 and several the slide bars 28 to be hindered and wear and tear, reduce service life, increase maintenance and operating difficulties on using.

For this reason, creator in the utility model relies on it to be engaged in plastic injection machine for many years and the associated mechanical Specialty Design is made and the experience of research and development, and through concentrating on studies and developing, create a kind of center of gravity adjusting device of innovation eventually, so that the horizontal level of movable die wall all around direction is effectively adjusted.

Summary of the invention

The main purpose of the center of gravity adjusting device of the movable die wall of ejaculator is can only adjust the problem of left and right directions horizontal level in order to solve existing adjusting device in the utility model.

The center of gravity adjusting device of the movable die wall of ejaculator is made up of slide block, adjustment bolt and extension corner bracket in the utility model; On slide block, be provided with several screws, in screw, be screwed into cooperate nut against and can adjust the adjustment bolt of height, this is respectively adjusted bolt and is provided with the projection that can be presented in movable die wall and the described extension corner bracket below locating hole.This adjusting device is by means of the fixed forward and backward and left and right direction level height that can adjust this activity die wall simultaneously that closes of the spiral shell of nut, each lining of movable die wall is aligned really and parallel consistent with the longitudinal center line of slide bar, eliminate retardance and loss that skew is produced, effectively increase the smooth and easy and service life of sliding.

The center of gravity adjusting device of the movable die wall of ejaculator is because the both sides group in movable die wall bottom is provided with the extension corner bracket in the utility model, thereby Support Position that can prolongation activity die wall and adjust effect, and the mode that this extension corner bracket employing activity group is established, wall processing for movable die wall does not have obstruction, in addition, also can according to circumstances do the dismounting combination, it is convenient to use.
