Description

Technical Field

[0001] The utility model relates to a template sliding foot mechanism, belonging to the technical field of injection molding machines. Background Art

[0002] An injection molding machine is a device for processing plastic products. For the mold used for injection molding, there are requirements for the parallelism between the moving template and the fixed template of the injection molding machine. In an injection molding machine, a sliding foot mechanism is usually adopted to adjust the relative position between the moving template and the fixed template to ensure the parallelism between the moving template and the fixed template. That is, a sliding seat is installed at the bottom of the moving template, and the sliding seat is slidably installed on the guide rail bar. Thus, during the movement of the moving template, the sliding seat slides along the guide rail bar to realize the limitation of the movement track of the moving template. At present, the weight of the moving template acts completely on the structure formed by the sliding seat and the guide rail bar, which requires higher structural strength for the sliding seat and the guide rail bar. Moreover, affected by the weight of the moving template, the sliding seat and the guide rail bar are worn more, affecting the service life of the sliding seat and the guide rail bar. Therefore, it is necessary to design a template sliding foot mechanism that can prevent the weight of the moving template from acting completely on the structure formed by the sliding seat and the guide rail bar. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a template sliding foot mechanism to solve the problems raised in the above background art. The utility model prevents the weight of the moving template from acting completely on the structure formed by the sliding seat and the guide rail bar, and prolongs the service life of the sliding seat and the guide rail bar.

[0004] To achieve the above purpose, the utility model is realized through the following technical solutions: A template sliding foot mechanism includes a guide rail bar, on which a sliding seat for installing at the bottom of the template is slidably installed. One side surface of the sliding seat is installed with a straight cylinder through a connecting piece. The straight cylinder is arranged vertically. The inner surface of the straight cylinder is processed with internal threads, and the internal threads of the straight cylinder are connected with a threaded column. The lower end of the threaded column is installed with a universal wheel in contact with the ground. A pin hole for inserting a lengthening rod is opened on the outer surface of the lower end of the threaded column, and the pin hole is arranged along the radial direction of the threaded column.

[0005] Furthermore, the connecting piece includes a support plate. One side surface of the sliding seat is fixedly connected with the support plate. The support plate is arranged horizontally. A strip-shaped groove is opened on the upper surface of the support plate, and the strip-shaped groove is arranged perpendicular to the guide rail bar. An ear plate is inserted in the strip-shaped groove. The lower end of the ear plate extends to the lower side of the support plate and is fixedly connected with a support plate. The support plate is fixed at the upper end of the straight cylinder and the support plate is in sliding contact with the support plate. The ear plate is connected with the support plate through an adjusting piece.

[0006] Further, the adjusting member includes a threaded rod. A through hole is formed in one side surface of the ear plate. The through hole is arranged above the support plate. A threaded rod is inserted into the through hole. The threaded rod is arranged along the length direction of the strip-shaped groove. Both ends of the threaded rod are fixedly connected to the support plate. A first nut and a second nut are threadedly connected to the threaded rod. The first nut and the second nut are arranged on both sides of the ear plate along the length direction of the threaded rod.

[0007] Further, positioning ears are fixedly connected to both ends of the threaded rod. The positioning ears are fixedly connected to the support plate.

[0008] Further, connecting ears are fixedly connected to the upper positions of two parallel side surfaces of the sliding seat. Two fixing holes for inserting screws are formed in the upper surface of the connecting ear. The support plate is fixedly connected to one of the connecting ears.

[0009] Further, a plurality of uniformly arranged rib strips are fixedly connected to the lower surface of the support plate. The rib strips are fixedly connected to the connecting ears.

[0010] Further, the connecting ear and the sliding seat are of an integrally formed structure. The connecting ear and the sliding seat are arranged perpendicular to each other.

[0011] Further, a groove is formed by downward depression on the upper surface of the supporting plate. The lower end of the ear plate is fixedly connected in the groove.

[0012] Advantages of the utility model:

[0013] 1. A structure formed by installing a straight cylinder, a threaded column and a universal wheel on one side surface of the sliding seat. Adjust the length of the threaded column in the straight cylinder to make the universal wheel contact the ground. Then, during the movement of the sliding seat along the guide rail strip, the sliding seat drives the universal wheel to roll along the ground through the straight cylinder and the threaded column. At this time, the structure formed by the universal wheel, the threaded column and the straight cylinder jointly plays a role in supporting the sliding seat, so that a part of the weight of the moving template is transferred to the ground, preventing the weight of the moving template from acting completely on the structure formed by the sliding seat and the guide rail strip, and extending the service life of the sliding seat and the guide rail strip.

[0014] 2. Adjust the position of the ear plate along the strip-shaped groove. At this time, the relative position between the supporting plate and the support plate changes, that is, the contact position between the universal wheel and the ground changes. At the same time, the threaded rod slides along the through hole relative to the ear plate. When the contact range between the universal wheel and the ground meets the requirements, the relative position between the threaded rod and the ear plate can be limited by using the first nut and the second nut, so as to realize that the universal wheel contacts different areas of the ground and avoid the universal wheel always contacting a certain area of the ground.

Specific embodiments

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please refer to Figure 1 , the present utility model provides a technical solution: a template sliding foot mechanism, including a guide rail bar 1, on which a sliding seat 2 for installing at the bottom of the template is slidably installed. On the upper positions of two parallel sides of the sliding seat 2, connecting ears 16 are fixedly connected. Among them, the connecting ear 16 and the sliding seat 2 are of an integrally formed structure, and the connecting ear 16 and the sliding seat 2 are arranged perpendicular to each other. On the upper surface of the connecting ear 16, two fixing holes for inserting screws are provided. Installing the connecting ear 16 with fixing holes on the sliding seat 2 facilitates the connection between the sliding seat 2 and the template.

[0023] Refer to Figures 1-4, a connecting ear 16 fixedly connected to one side of the sliding seat 2 is fixedly connected to a horizontally arranged support plate 3. A plurality of uniformly arranged ribs are fixedly connected to the lower surface of the support plate 3. The ribs are fixedly connected to the connecting ear 16. The design of the ribs improves the mechanical strength of the connection between the support plate 3 and the sliding seat 2. A strip-shaped groove 9 is formed on the upper surface of the support plate 3. The strip-shaped groove 9 is arranged perpendicular to the guide rail strip 1. An ear plate 13 is inserted into the strip-shaped groove 9. The lower end of the ear plate 13 extends to the lower side of the support plate 3 and is fixedly connected to the support plate 8. A groove is formed by the upper surface of the support plate 8 being recessed downward, so that the lower end of the ear plate 13 is fixedly connected in the groove, increasing the connection range between the ear plate 13 and the support plate 8. The support plate 8 is fixed to the upper end of the straight cylinder 4 and the support plate 8 is in sliding contact with the support plate 3. A through hole 15 is formed on one side surface of the ear plate 13. The through hole 15 is arranged above the support plate 3. A threaded rod 11 is inserted into the through hole 15. The threaded rod 11 is arranged along the length direction of the strip-shaped groove 9. Positioning ears 10 are fixedly connected to both ends of the threaded rod 11. The positioning ears 10 are fixedly connected to the support plate 3. A first nut 12 and a second nut 14 are threadedly connected to the threaded rod 11. The first nut 12 and the second nut 14 are arranged on both sides of the ear plate 13 along the length direction of the threaded rod 11. Adjust the position of the ear plate 13 along the strip-shaped groove 9. At this time, the relative position between the support plate 8 and the support plate 3 changes, that is, the contact position of the universal wheel 6 with the ground changes. At the same time, the threaded rod 11 slides relative to the ear plate 13 along the through hole 15. When the contact range of the universal wheel 6 with the ground meets the requirements, the relative position between the threaded rod 11 and the ear plate 13 can be restricted by using the first nut 12 and the second nut 14, realizing that the universal wheel 6 contacts different areas of the ground and avoiding the universal wheel 6 always contacting a certain area of the ground.

[0024] Refer to Figure 1 , the straight cylinder 4 is arranged vertically. The inner surface of the straight cylinder 4 is processed with internal threads. A threaded column 5 is connected to the internal threads of the straight cylinder 4. A universal wheel 6 in contact with the ground is installed at the lower end of the threaded column 5. A pin hole 7 for inserting an extension rod is formed on the outer surface of the lower end of the threaded column 5. The pin hole 7 is arranged along the radial direction of the threaded column 5. Insert the extension rod into the pin hole 7 to facilitate rotating the threaded column 5 by using the extension rod. Install the structure formed by the straight cylinder 4, the threaded column 5 and the universal wheel 6 on one side surface of the sliding seat 2. Adjust the length of the threaded column 5 in the straight cylinder 4 to make the universal wheel 6 contact the ground. Then, during the movement of the sliding seat 2 along the guide rail strip 1, the sliding seat 2 drives the universal wheel 6 to roll along the ground through the straight cylinder 4 and the threaded column 5. At this time, the structure formed by the universal wheel 6, the threaded column 5 and the straight cylinder 4 jointly plays a role in supporting the sliding seat 2, transferring a part of the weight of the moving template to the ground and preventing the weight of the moving template from completely acting on the structure formed by the sliding seat 2 and the guide rail strip 1, extending the service life of the sliding seat 2 and the guide rail strip 1.

This narrative style of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
