A large injection molding machine shooting oil cylinder extension rod support structure

Abstract

This invention provides a support structure for the extension rod of a large injection molding machine's injection transfer cylinder, comprising at least two symmetrically arranged support columns; each support column has a fixed base plate at its lower end, which is positioned and connected to the machine frame; each support column has a fixed support plate at its upper end, and an adjustable support frame is mounted on the support plate. A support wheel is rotatably mounted on the support frame, supporting the injection transfer cylinder. This invention effectively supports and holds the injection transfer cylinder, facilitating relative sliding and ensuring good support during the support process. Furthermore, during the support of the injection transfer cylinder, the angle of the adjustment plate can be adjusted as needed by adjusting the adjusting bolts, thereby adjusting the support height of the injection transfer cylinder.

Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, and in particular to a support structure for the extension rod of the injection displacement cylinder of a large injection molding machine. Background Technology

[0002] Currently, different injection molding machine options are available to meet different customer needs. Customers can freely choose different mold closing and injection methods. To meet these needs, more and more large injection molding machines have emerged. However, there are many problems with the support of the injection unit during actual assembly.

[0003] For large injection units, due to the high injection volume required per unit time, a longer barrel is necessary to ensure the polymer material melts fully within it. Correspondingly, an excessively long barrel necessitates an equally long injection cylinder at the front of the injection unit. Current injection molding machines only have a support structure below the barrel for support; the injection cylinder is located to the side of the barrel without any special support structure.

[0004] Because the injection cylinder has a relatively slender structure and is relied upon to control the movement of the injection platform, its front end may sink after prolonged operation, creating a height difference that causes the injection platform to shift position, leading to machine errors and malfunctions. Therefore, it is necessary to further improve the design to address the issue of the injection cylinder being unsupported and prone to front-end sinking. Utility Model Content

[0005] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides a support structure for the extension rod of the injection cylinder of a large injection molding machine, which can effectively support the injection cylinder and adjust the height difference formed by the sinking of the front end of the injection cylinder as needed, so as to effectively ensure the normal operation of the injection unit.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a support structure for the extension rod of a large injection molding machine's injection displacement cylinder, which is set on the frame of the injection molding machine to support the injection displacement cylinder, including at least two symmetrically arranged support columns; each support column has a fixed base plate at its lower end, and the fixed base plate is positioned and connected to the frame; each support column has a support plate fixed at its upper end, and the support plate is provided with an adjustable support frame, and the support frame is rotatably provided with a support wheel, which supports and supports the injection displacement cylinder.

[0007] In the above solution, to address the problem of the injection cylinder's front end being unsupported and prone to sinking, a support column is further designed on the frame. The support column, support plate, and support wheel work together to effectively support the injection cylinder, avoiding the injection stage deviation caused by the front end of the injection cylinder sinking during operation, and effectively ensuring the normal operation of the injection unit.

[0008] Furthermore, in the angle adjustment of the support plate, two supporting vertical plates are fixed on the support plate, and a hinge shaft is rotatably connected between the two supporting vertical plates; one end of the support frame is hinged to the supporting vertical plate through the hinge shaft, and the other end is provided with an angle adjustment hole, which is a threaded hole. An adjusting bolt is threaded into the angle adjustment hole, and the lower end of the adjusting bolt abuts against the support plate. The adjusting bolt rotates relative to the angle adjustment hole, thereby driving the support frame to rotate relative to the hinge shaft.

[0009] Furthermore, the support frame has a groove-shaped structure, wherein an angle adjustment hole is opened at one end of the groove bottom, and the two sides of the groove wall at the other end of the groove bottom extend outward and are hinged to the hinge shaft; the two sides of the groove wall of the groove structure have mounting holes at the positions between the angle adjustment hole and the hinge shaft, and mounting shafts are rotatably mounted thereon, and support wheels are rotatably connected to the mounting shafts.

[0010] Furthermore, to better support the injection cylinder, the outer circumferential surface of the support wheel is an arc-shaped surface that matches the shape of the injection cylinder. This arc-shaped surface provides support and positioning for the injection cylinder.

[0011] Furthermore, the support column is obliquely arranged relative to the fixed base plate, and the angle between the support column and the fixed base plate ranges from 70° to 80°.

[0012] Furthermore, a connecting reinforcing plate connects the two symmetrically arranged support columns. This connecting reinforcing plate allows the support columns on both sides to be connected, further enhancing their support stability.

[0013] Furthermore, the connecting reinforcing plate and the supporting column have a certain degree of adjustability. The connecting reinforcing plate has waist holes at both ends, and the connecting reinforcing plate is adjustablely connected to the corresponding side supporting column through the waist holes by positioning bolts.

[0014] Furthermore, a support reinforcement plate is fixed between the lower end face of the support plate and the support frame. The support reinforcement plate further enhances the support effect between the support plate and the support frame.

[0015] The beneficial effects of this utility model are that the extended rod support structure for the injection transfer cylinder of a large injection molding machine provided by this utility model has a reasonable structural design, which can effectively support and support the injection transfer cylinder. During the support process, it is convenient for the injection transfer cylinder to slide relative to each other and be well supported. At the same time, during the support of the injection transfer cylinder, the angle of the angle adjustment plate can be adjusted as needed by adjusting the adjusting bolts, thereby adjusting the support height of the injection transfer cylinder, further ensuring the accurate position of the front end of the injection transfer cylinder, and avoiding the sinking of the front end of the injection transfer cylinder after long-term operation, which would cause a height difference and lead to errors in the injection unit and failure to operate normally at the set height.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show the components relevant to the present invention. Orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0022] like Figures 1 to 3 The illustrated support structure for the extension rod of a large injection molding machine's injection displacement cylinder is the preferred embodiment of this utility model. This support structure is mounted on the frame of the injection molding machine and is used to support the injection displacement cylinder. It includes two symmetrically arranged support columns 8.

[0023] Each support column 8 has a fixed base plate 9 at its lower end. The fixed base plate 9 and the support column 8 can be connected by, but are not limited to, welding or bolt fixing. The fixed base plate 9 is fixed to the frame on both sides of the support column 8 by bolts and washers.

[0024] Each support column 8 has a support plate 7 fixed to its upper end. In this embodiment, to avoid interference between the support plate 7 and the injection cylinder, injection table, or material cylinder, the support plate 7, after being fixed to the top of the support column 8, typically forms an inverted L-shaped structure with the support plate 7 and the support column 8 opening outwards. Corresponding to the opening direction of the L-shaped structure, a support reinforcement plate 12 is fixed between the lower end face of the support plate 7 and the support frame. The support reinforcement plate 12 further enhances the support effect between the support plate 7 and the support frame.

[0025] Two supporting vertical plates 6 are fixed on the support plate 7, and a hinge shaft 5 is rotatably connected between the two supporting vertical plates 6. The support frame has a groove-shaped structure, in which an angle adjustment hole is opened at one end of the groove bottom 3, and the two side walls 4 at the other end of the groove bottom 3 extend outward and are hinged to the hinge shaft 5. The angle adjustment hole is a threaded hole, and an adjusting bolt 11 is threaded into the angle adjustment hole. The lower end of the adjusting bolt 11 abuts against the support plate 7. The adjusting bolt 11 rotates relative to the angle adjustment hole, thereby driving the support frame to rotate relative to the hinge shaft 5. The two side walls 4 of the groove structure have mounting holes at the positions between the angle adjustment hole and the hinge shaft 5, and mounting shafts are rotatably provided on them. Support wheels 2 are rotatably connected to the mounting shafts. The support wheels 2 are used to roll and support the injection cylinder. The outer circumference of the support wheels 2 is an arc-shaped surface that matches the shape of the injection cylinder. Through the cooperation of the arc-shaped surface, support and positioning of the injection cylinder are provided.

[0026] During the debugging process, by adjusting the rotation of the adjusting bolt 11, the support frame can be rotated around the hinge shaft 5 as the rotation center line, thereby adjusting the angle of the support frame relative to the support vertical plate 6, and thus adjusting the lifting height of the support frame, that is, adjusting the support height of the support wheel 2. While effectively supporting and supporting the injection cylinder, the lifting height of the injection cylinder can be adjusted to a certain extent, thereby avoiding its sinking and causing a height difference, avoiding the deviation of the injection table caused by the sinking of the front end of the injection cylinder during operation, effectively ensuring the normal operation of the injection unit, and avoiding the sinking of the front end of the injection cylinder after long-term operation, which would cause the injection unit to malfunction and fail to operate normally. Even if sinking occurs, it can be adjusted using the adjusting bolt 11 to lift and correct the sinking.

[0027] In this embodiment, to further improve the support effect of the support column 8, the support column 8 is obliquely arranged relative to the fixed base plate 9, and the angle between the support column 8 and the fixed base plate 9 ranges from 70° to 80°, preferably 78° for the required lifting height. Simultaneously, the oblique direction of the support column 8 is towards the rear end of the injection cylinder, meaning the support column 8 supports the injection cylinder at its front end. The front end of the support column 8 forms a stable support angle with the frame plane, and together with the normal positioning connector at the rear end of the injection cylinder, a stable support structure can be formed.

[0028] Meanwhile, a connecting reinforcing plate 1 can be further designed between the two symmetrically arranged support columns 8. Each end of the connecting reinforcing plate 1 has a slotted hole 10, and the connecting reinforcing plate 1 is adjustablely connected to the corresponding side support column 8 via positioning bolts through the slotted holes 10. The adjustable design of the connecting reinforcing plate 1 facilitates the connection of the support columns 8 on both sides, further enhancing the support stability of the support columns 8.

[0029] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
