Definitions
- the present invention relates to a mold support system, which supports the weight of the movable part of an injection mold, and a method for regulating the position of a movable part of a mold using said support system.
- Conventional injection molds comprise a fixed part and a mobile part.
- the fixed part is perfectly centered and is motionless with respect to the injection machine.
- the mobile part moves horizontally on sliding elements to close the mold.
- This moving part has a very high weight, more than 7,000 kg, and is located offset with respect to the sliding elements of the machine; This causes the sliding elements to be subject to significant wear. In this way, the mobile part of the mold tends to lift vertically and, when closing the machine, there are problems to center the moving part vertically with respect to the fixed part.
- This mold carrier skate is normally a support beam to the mobile plate of the injection machine, where the mobile part of the mold is supported.
- the objective of the present invention is to provide a support system and a method that allow a comfortable and efficient regulation of the support points of the mold carrier with the movable part of an injection mold.
- the mold support system comprises a mold carrier slide provided with vertically movable support elements to support the movable part of the mold, and is characterized in that said support elements are elements Hydraulic support.
- said hydraulic support elements comprise two or more hydraulic cylinders, and are arranged so that each hydraulic support element vertically traverses the mold carrier slide, protruding upper and lower.
- each hydraulic cylinder comprises a protector at its upper end and, in addition, each hydraulic support element comprises a locking flange, which is advantageously arranged at the bottom of each hydraulic support element.
- This flange under normal conditions, is mechanically locked, and to be unlocked (operation that must be performed to move the support elements vertically), it must be hydraulically operated. This allows once the height of the support elements is adjusted, the hydraulics can be completely dispensed with to maintain their position.
- the support system comprises a regulation plate on each side to regulate the horizontal positioning of the mold carrier slide with respect to the mobile plate of the injecting machine.
- the present invention relates to a method for regulating the position of the support elements to a movable part of a mold using the support system mentioned above, which comprises the following steps:
- this pressure is programmable, and must be adjusted taking into account the dimensions of the hydraulic cylinders that are mounted, and the weight of the part of the mold with which it is going to work.
- this pressure we are ensuring that the support elements have touched the surface of the mold, and the force that they must exert must be of the order of approximately 10% of the weight of the mold, to ensure that it does not force or move vertically mold.
- Figure 1 is a perspective view of the mold support system according to the present invention, mounted on a mold, where the movable part of said mold is shown; Y
- Figure 2 is a front view of the mold support system according to the present invention, mounted on the mold of Figure 1.
- the support system according to the present invention is used in a mold, for example, an injection mold, whose moving part has an approximate weight of 10,000 kg, comprising a fixed part (not represented in the drawings) and a movable part 2, which moves horizontally to close the mold.
- said mobile part 2 is mounted on the mobile plate 1 of the injecting machine.
- the movable part 2 of the mold is supported by a support system comprising a mold carrier slide 3, which slides on sliding elements 4.
- the mold carrier skate 3 comprises hydraulic support elements 5, such as two or more hydraulic cylinders, which pass through said mold carrier skate 3 and protrude superiorly and internally, its upper end being in contact with the lower part of the movable part 2 of the mold, of according to the embodiment represented.
- Said hydraulic cylinders 5 comprise a flange 6 in its lower part, in accordance with the embodiment shown.
- the protector 7, which for example is formed by a sheet housing, prevents accidental bumps on the hydraulic cylinders 5, which due to the weight of the mold could break them.
- the flange 6 allows to block the displacement of each hydraulic cylinder 5 when they have been placed in the desired position, which will be described below.
- the support system is connected in solidarity with the mobile plate of the injecting machine, by means of two side plates 8.
- the support system In accordance with the present invention, it comprises the regulating plates 8, provided with a plurality of holes for placing a fixing element between the mold carrier 3 and the mobile plate 1 of the machine, depending on the relative horizontal position want to get.
- the present invention also relates to the process for regulating the position of the movable part 2 of a mold using the support system mentioned above.
- one of the hydraulic support elements 5 moves until it comes into contact with the movable part 2, directly or with the movable plate 2.
- the hydraulic support element 5 will move until it detect a predetermined pressure, which will indicate that the support element Hydraulic 5 is in the correct position, supporting the weight of the moving part 2.
- each hydraulic support element 5 is stopped, blocking the vertical displacement of each hydraulic support element by said flange 6, preventing the hydraulic support element 5 from moving.
- the maximum travel of the support elements 5 is intended to be 50 mm and its minimum travel is 25 mm, with an accuracy of 0.1 mm.
