Description

Technical Field

[0001] This utility model belongs to the field of injection molding machine technology, specifically relating to a two-plate sliding foot support structure. Background Technology

[0002] When the injection molding machine is working, the tie rod drives the second platen to move on the machine body guide rail. However, the weight of the second platen, mold, tail platen and other mold components is relatively large, which can cause abnormal pulling between the tie rod and the second platen, preventing the injection molding machine from operating normally and affecting the quality of the product. Therefore, a second platen sliding foot device is installed between the second platen and the machine body.

[0003] Chinese Patent No. CN 214266432 U discloses an adjustable two-plate sliding foot with an oblique inclination. The sliding foot includes an upper sliding foot and a lower sliding foot. The lower sliding foot is located at both ends of the bottom of the upper sliding foot. The bottom surfaces of both ends of the upper sliding foot and the upper surface of the lower sliding foot are inclined surfaces that fit together. A protruding plate is provided at the end of the lower sliding foot away from the upper sliding foot. A U-shaped groove is provided in the middle of the protruding plate, and a hexagonal screw is provided in the U-shaped groove. Hexagonal screws 2 and 3 are respectively provided on both sides of the U-shaped groove on the protruding plate, and both hexagonal screws 2 and 3 pass through the protruding plate. A protruding plate 2 is provided at one end of the upper sliding foot, and hexagonal screws 4 and 5 are provided on the protruding plate.

[0004] However, the above-mentioned device has the following problems during use:

[0005] The upper and lower sliding feet can move along a fitted inclined plane. During movement, the direction of movement of the upper and lower sliding feet is limited only by a single hexagonal screw to prevent relative misalignment. However, the strength of the hexagonal screw is limited, and its limiting force on the forward and backward movement of the upper and lower sliding feet is also limited. When the two plates connected by the upper sliding foot are large, especially when the two plates have inertial forces due to high-speed movement, the bolts may bend when the upper and lower sliding feet misalign, resulting in misalignment. Therefore, this application proposes a two-plate sliding foot support structure. Utility Model Content

[0006] The purpose of this utility model is to provide a two-plate sliding foot support structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a two-plate sliding foot support structure, comprising a two-plate body, a two-plate slider seat, and a two-plate slider, wherein a plurality of tie rods are inserted into the two-plate body, and the two-plate body is connected to the two-plate slider seat;

[0008] The two-plate slider seat is provided with a first inclined surface, which is in contact with the second inclined surface in the two-plate slider;

[0009] The two-plate slider is provided with two side plates at the position corresponding to the second inclined surface, and the outer wall of the two-plate slider seat abuts against the outer walls of the two side plates.

[0010] Preferably, there are four pull rods, and the four pull rods are respectively inserted into the four corners of the two-plate body.

[0011] Preferably, a copper sleeve is inserted at the mounting hole position corresponding to the tie rod on the two plate bodies, and the copper sleeve is interference-fitted with the inner wall of the mounting hole.

[0012] Preferably, two pressure caps are provided at each end of the copper sleeve, and the pressure caps are connected to the outer wall of the two-plate body by screws.

[0013] Preferably, the two-plate slider seat and the two-plate body are connected by large bolts.

[0014] Preferably, the bottom of the two-plate slider seat is provided with two first inclined surfaces, and the two first inclined surfaces are symmetrically distributed about the center line of the two-plate slider seat. The first inclined surface has a starting end on the side closer to the center line of the two-plate slider seat and an ending end on the other side, with the height of the starting end being lower than the height of the ending end.

[0015] Preferably, the two-plate slider seat is inserted between the two side plates.

[0016] Preferably, the two side walls of the two-plate slider seat abut against the outer wall of the two side plates on the side away from the second inclined surface.

[0017] Preferably, a fastening bolt is screwed into the second-plate slider seat, and the fastening bolt is inserted into the U-shaped groove in the second-plate slider, and the fastening bolt and the U-shaped groove can slide up and down relative to each other.

[0018] Preferably, a limit bolt is screwed into the two-plate slider, a slider copper pad is installed below the two-plate slider, and a steel strip is provided on the lower side of the slider copper pad.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. When using this utility model, the mold mounting surface is used to install the mold. It is integrated and protrudes onto the two-plate body. The main function of the two-plate sliding foot support structure is to support the weight of the two-plate body and the mold, and to guide the two-plate body in the vertical direction. The pull rod and copper sleeve are horizontal front-to-back guides, preventing the pull rod and copper sleeve from bearing the load in the vertical direction. The combined guidance in the vertical and horizontal front-to-back directions makes the two-plate body run more smoothly at high speed.

[0021] Second, the two-plate sliding foot support structure in this utility model supports vertical forces, preventing insufficient support from causing the tie rod to bear excessive vertical forces, thus avoiding premature damage due to wear and lateral loads. After the mold is installed, this two-plate sliding foot support structure further prevents excessive overturning forces on the two plates, ensuring smooth operation of the two plates, preventing wear on the tie rod, and the integrated reinforced structure prevents damage from overturning forces.

[0022] Third, in this utility model, the two plate bodies are connected to the two plate sliders through the two plate slider seat, and the two plate slider seat is inserted between the two side plates. The two side plates provide obstruction to the movement of the two plate slider seat and the two plate bodies in the front-back direction, so that the two plate slider seat and the two plate slider can only move relative to each other in the left and right, and cannot move relative to each other in the front and back, thus avoiding the situation where the two plate slider seat and the two plate slider separate from each other.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-5A two-plate sliding foot support structure includes a two-plate body 1, a two-plate slider seat 5, and a two-plate slider 6. A mold mounting surface 101 is provided inside the two-plate body 1, and the mold mounting surface 101 is integrally set on the two-plate body 1. The mold mounting surface 101 is used for mold installation. The two-plate sliding foot support structure on the lower side of the two-plate body 1 is for supporting the weight of the mold and the two-plate body 1. Several tie rods 4 are inserted inside the two-plate body 1. There are four tie rods 4 in total, and the four tie rods 4 are respectively inserted into the four corners of the two-plate body 1. The tie rods 4 are slidably connected to the two-plate body 1. The tie rods 4 can support the two-plate body 1. In this way, most of the weight of the two-plate body 1 itself is borne by the four tie rods 4, and the weight borne by the bottom two-plate slider seat 5 and the two-plate slider 6 is relatively small. This allows the components to be used for a long time.

[0031] The pull rod 4 needs to slide relative to the second plate body 1. In order to avoid damage to the internal channels of the pull rod 4 and the second plate body 1 due to direct friction, a copper sleeve 2 is inserted at the mounting hole position of the second plate body 1 corresponding to the pull rod 4. The copper sleeve 2 is interference-fitted with the inner wall of the mounting hole. Two pressure caps 3 are respectively provided at both ends of the copper sleeve 2. The pressure caps 3 are connected to the outer wall of the second plate body 1 by screws.

[0032] The copper sleeve 2 is inserted into the body 1 of the second plate and slides relative to the pull rod 4. Even if wear occurs during the movement, only the inside of the copper sleeve 2 is worn. As a consumable part, the copper sleeve 2 can be replaced after wear. Moreover, the copper sleeve 2 is made of copper, which is relatively soft. When it wears relative to the pull rod 4, it is usually the copper sleeve 2 that is worn, and the wear on the pull rod 4 is negligible. In this way, the pull rod 4 can be used for a long time, and only the copper sleeve 2 needs to be replaced. Overall, the number of consumable parts that need to be replaced during the use of the pull rod 4 and other components in the device is small, and the replacement cost is low.

[0033] The second plate body 1 connects to the second plate slider seat 5. For details, please refer to... Figure 4 The second plate slider seat 5 is connected to the second plate body 1 by a large bolt, which is screwed into the interior of the second plate slider seat 5 from the second plate body 1.

[0034] Specifically, the second-plate slider seat 5 is provided with a first inclined surface 501, which is in contact with the second inclined surface 601 in the second-plate slider 6. It should be noted that the bottom of the second-plate slider seat 5 is provided with two first inclined surfaces 501, and the two first inclined surfaces 501 are symmetrically distributed about the center line of the second-plate slider seat 5. The first inclined surface 501 has a starting end on the side closer to the center line of the second-plate slider seat 5 and an ending end on the other side. The height of the starting end is lower than the height of the ending end.

[0035] It should be noted that two side plates 602 are provided at the position of the second inclined surface 601 corresponding to the second plate slider 6. The outer wall of the second plate slider seat 5 abuts against the outer walls of the two side plates 602, so that the second plate slider 6 and the second plate slider seat 5 can only move relative to each other along the first inclined surface 501 and the second inclined surface 601. There are two cases here. The first case can be referred to Figure 4 When the second plate slider seat 5 is inserted between the two side plates 602, the second plate slider 6 and the second plate slider seat 5 can only slide relative to each other in the left and right, and cannot move relative to each other in the front and back. In the second case, the two side walls of the second plate slider seat 5 can be abutted against the outer wall of the two side plates 602 away from the second inclined surface 601, which can prevent the second plate slider seat 5 and the second plate slider 6 from moving relative to each other in the front and back.

[0036] The first inclined surface 501 is set on the lower end face of the second plate slider seat 5, while the second inclined surface 601 is set on the second plate slider 6. The side plate 602 is also set on the second plate slider 6. The connection between the two only has two components, the second plate slider seat 5 and the second plate slider 6. Both components are processed in an integrated manner. The number of components that need to be assembled at the connection is small, and the disassembly and assembly are more convenient. Moreover, the integrated component is stronger and has a longer service life than the assembled component.

[0037] In a further embodiment, a fastening bolt 604 is screwed into the second-plate slider seat 5. The fastening bolt 604 is inserted into the U-shaped groove 603 in the second-plate slider 6, and the fastening bolt 604 and the U-shaped groove 603 can slide up and down relative to each other.

[0038] More specifically, a limiting bolt 605 is screwed into the second-plate slider 6. There is a gap between the limiting bolt 605 and the second-plate slider seat 5 in its initial state. A slider copper pad 7 is installed below the second-plate slider 6, and a steel strip 8 is provided on the lower side of the slider copper pad 7. The slider copper pad 7 is the part that directly contacts the steel strip 8. Wear will occur during the relative movement of the two. Therefore, a slider copper pad 7 is provided on the lower side of the second-plate slider 6.

[0039] Working principle:

[0040] The two-plate body 1 is connected to the two-plate slider 6 via the two-plate slider seat 5. The two-plate slider seat 5 is inserted between the two side plates 602. The two can only move relative to each other left and right, but cannot move relative to each other front and back, thus avoiding the situation where the two-plate slider seat 5 and the two-plate slider 6 separate from each other.

[0041] A second-plate slider seat 5 is provided on the lower side of the second-plate body 1. The first inclined surface 501 inside the second-plate slider seat 5 is provided on the lower end surface of the second-plate slider seat 5, while the second inclined surface 601 is provided on the second-plate slider 6. At the same time, the side plate 602 is also provided on the second-plate slider 6. There are only two components at the connection between the two: the second-plate slider seat 5 and the second-plate slider 6. Both components are processed in an integrated manner. The number of components that need to be assembled at the connection is small, and the disassembly and assembly are more convenient. Moreover, the integrated component is stronger and has a longer service life than the assembled component.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
