Description

Technical Field

[0001] This utility model relates to the field of molding equipment technology, and in particular to an automatic separation mechanism between the mold and the machine frame station. Background Technology

[0002] Traditional compression molding equipment involves pushing the mold into a station located within the frame for heating or cooling, and then removing the mold from the frame. Each time the mold moves in and out of the station, it directly rubs against the surface of the lower heating or cooling plate, causing physical wear and tear on these plates. Over time, this affects the heating or cooling efficiency.

[0003] Therefore, there is an urgent need to propose an automatic separation mechanism between the mold and the machine frame station, which can avoid frictional contact between the mold and the heating plate or cooling plate, and reduce the physical wear of the mold on the lower heating plate and the lower cooling plate. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an automatic separation mechanism for molds and machine frame stations.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: An automatic separation mechanism for molds from machine frame workstations is provided to separate molds from workstations within a machine frame. The machine frame includes a lifting drive mechanism, an upper plate, and a lower plate. It comprises two sets of lifting components and a mold. The two sets of lifting components are liftably mounted on both sides of the lower plate. The mold is connected to the lifting components and located on the lower plate. Support components are provided on both sides of the upper plate, and these support components are detachably connected to the lifting components. The lifting drive mechanism is connected to the upper plate. When the lifting drive mechanism drives the upper plate upward away from the lower plate and the support components are connected to the lifting components, the mold and lifting components move upward with the upper plate, separating the mold from the lower plate. When the lifting drive mechanism drives the upper plate downward toward the lower plate and the mold is located on the lower plate, the support components separate from the lifting components.

[0006] Preferably, the lifting assembly includes a mounting plate and an extension plate. The mounting plate is liftable and mounted on the frame and is located on one side of the lower plate.

The support assembly includes a support plate, which is fixedly mounted on the upper plate and is always located below the extension plate.

[0007] Preferably, the lifting assembly also includes an adjusting screw, which is mounted on the extension plate. The bottom of the adjusting screw has an abutment portion, and the distance between the abutment portion and the extension plate can be changed by rotating the adjusting screw. The abutment portion and the support plate can be detachably connected.

[0008] Preferably, the assembly also includes a frame fixing plate, a guide rod, a lifting rail, and a mounting base.

The mold is installed inside the mold frame.

[0010] Preferably, the mold also includes a positioning recess and a positioning telescopic shaft. The positioning recess is mounted on the mold frame, and the positioning telescopic shaft is mounted on the mounting plate. When the mold frame drives the mold to slide to the first position, the positioning telescopic shaft is engaged in the positioning recess.

[0011] Preferably, the inner edge of the positioning concave shaft is arc-shaped, and one end of the positioning telescopic shaft is arc-shaped.

[0012] Preferably, the support plate is provided with a clearance groove, which provides clearance space for the positioning telescopic shaft and the positioning concave shaft when the lifting drive mechanism drives the upper plate to descend.

[0013] Preferably, a mold frame blocking block is also included. The mold frame blocking block is installed on one side of the mold moving track. When the mold frame is slid to the second position, the mold frame blocking block is located on the side of the mold frame away from the lower plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) The automatic separation mechanism between the mold and the machine frame station proposed in this application drives the mold to move up and down through the lifting component, so as to separate the mold from the station in the machine frame, which solves the problem of physical wear of the lower plate caused by direct friction between the mold and the lower plate surface during the process of the mold entering and leaving the station.

The accompanying drawings are merely illustrative to facilitate understanding of the present invention, and their specific proportions can be adjusted according to design requirements. The vertical relationships of relative elements and the definitions of front / back in the graphics described herein should be understood by those skilled in the art to refer to the relative positions of the components; therefore, they can all be flipped to present the same component, and all of this should fall within the scope disclosed in this specification.

[0020] refer to Figures 1 to 6 This application proposes an automatic separation mechanism for a mold from a machine frame station, used to separate the mold from the station within a machine frame 1. The machine frame 1 includes a machine frame fixing plate 14, a lifting drive mechanism 11, an upper plate 12, and a lower plate 13. In a specific embodiment, refer to... Figure 1 and Figure 2The automatic separation mechanism between the mold and the machine frame includes two sets of lifting components 2, a mold, a guide rod 4, a lifting rail 9, a mounting base 5, a mold frame 6, and a mold transfer rail 7. The lower plate 13 is fixedly installed on the machine frame fixing plate 14. The guide rod 4 slides through the machine frame fixing plate 14, and a mounting base 5 is fixedly installed at one end of the guide rod 4. The lifting rail 9 is fixedly installed on the mounting base 5. The mounting plate 21 is fixedly connected to the mounting base 5 to guide the mounting base 5 when the lifting components 2, the mounting base 5, and the lifting rail 9 move up and down, ensuring that the lifting components 2 and the lifting rail 9 move up and down smoothly and that the mechanism operates stably. The two sets of lifting components 2 can be lifted and lowered on both sides of the lower plate 13. The mold transfer rail 7 is fixedly installed on the side of the lower plate 13 adjacent to the two sets of lifting components 2. The lifting rail 9 moves upward with the lifting components 2 until it is docked with the mold transfer rail 7. The mold frame 6 is slidably installed on the mold transfer rail 7 and can be slidably positioned between a first position on the lower plate 13 and a second position on one side of the lower plate 13 via the mold transfer rail 7. The mold is connected to the lifting assembly 2 and is located on the lower plate 13. Specifically, the mold is installed inside the mold frame 6 so that the mold, mold frame 6, mounting base 5, and mounting plate 21 located inside the mold frame 6 move up and down with the lifting assembly 2. Supporting assemblies 3 are provided on both sides of the upper plate 12, and the supporting assemblies 3 can be detachably connected to the lifting assembly 2. The lifting drive mechanism 11 is connected to the upper plate 12. When the lifting drive mechanism 11 drives the upper plate 12 to move upward away from the lower plate 13 and the supporting assemblies 3 are connected to the lifting assembly 2, the mold and the lifting assembly 2 move upward with the upper plate 12 and the mold is separated from the lower plate 13. When the lifting drive mechanism 11 drives the upper plate 12 to move downward toward the lower plate 13 and the mold is located on the lower plate 13, the supporting assemblies 3 are separated from the lifting assembly 2. The automatic separation mechanism of mold and frame station proposed by this utility model uses the lifting assembly 2 to drive the mold to move up and down to separate the mold from the station in the frame 1, which solves the problem of physical wear of the lower plate 13 caused by direct friction between the mold and the surface of the lower plate 13 during the process of the mold entering and leaving the station.

[0021] In a specific embodiment, the lifting assembly 2 includes a mounting plate 21, an extension plate 22, and an adjusting screw 23. The mounting plate 21 is liftably mounted on the frame 1 and is located on one side of the lower plate 13. The extension plate 22 is mounted on top of the mounting plate 21 and extends toward the mounting plate 21 located on the other side of the lower plate 13. The supporting assembly 3 includes a supporting plate 31, which is fixedly mounted on the upper plate 12 and is always located below the extension plate 22. The adjusting screw 23 is mounted on the extension plate 22, and the bottom of the adjusting screw 23 is provided with an abutment portion 231. By rotating the adjusting screw 23, the distance between the abutment portion 231 and the extension plate 22 is changed, thereby changing the height at which the mounting plate 21 and the extension plate 22 rise with the supporting plate 31. In the embodiments of this application, the mounting plate 21 and the extension plate 22 are integrally formed parts.

[0022] For details, please refer to Figure 3 The support plate 31 moves upward with the upper plate 12, driving the mounting plate 21 and the extension plate 22 upward until they stop. The support plate 31 then moves with the upper plate 12 to the target position. The distance between the position of the extension plate 22 before its upward movement and the target position of the support plate 31 is Dr. When the distance d between the contact part 231 and the extension plate 22 is equal to the first interval distance d1, the distance the extension plate 22 moves upward from the moment the contact part 231 just makes contact with the support plate 31 until the support plate 31 is in the target position is the first rise. The distance Du1 is equal to Dr + d1, meaning the lifting assembly 2 rises a distance of Du1. When the distance d between the contact part 231 and the extension plate 22 is equal to the second interval distance d2, the distance the extension plate 22 moves upward from the moment the contact part 231 just contacts the support plate 31 until the support plate 31 is at the target position is the second rising distance Du2, where Du2 = Dr + d1. If the first interval distance is less than the second interval distance, then the first rising distance is less than the second rising distance. In the embodiments of this application, the distance d between the contact part 231 and the extension plate 22 is adjusted by rotating the adjusting screw 23 to change the rising distance of the lifting assembly 2, thereby adjusting the rising distance of the mounting base 5 connected to the lifting assembly 2 and the lifting rail 9, so that the subsequent lifting rail 9 can dock with the mold moving rail 7, facilitating mold moving.

[0023] In a specific embodiment, refer to Figure 1 , Figure 4 and Figure 5 It also includes a positioning recess 81 and a positioning telescopic shaft 82. The positioning recess 81 is mounted on the mold frame 6, and the positioning telescopic shaft 82 is mounted on the mounting plate 21. When the mold frame 6 drives the mold to slide to the first position, the positioning telescopic shaft 82 is engaged in the positioning recess 81. The inner edge of the positioning recess 81 is arc-shaped, and one end of the positioning telescopic shaft 82 is arc-shaped. The positioning telescopic shaft 82 can extend and retract vertically. The structural design of the positioning recess 81 and the positioning telescopic shaft 82 facilitates the entry of the end of the positioning telescopic shaft 82 into the positioning recess 81 to position the mold, thereby placing the mold in a suitable position above the lower plate 13, which facilitates uniform heating or cooling of the mold in the future. Specifically, when the positioning concave shaft 81 moves with the mold frame 6 from outside the machine frame 1 toward the workstation inside the machine frame 1 and moves until the upper edge of the positioning concave shaft 81 abuts against the positioning telescopic shaft 82, the positioning concave shaft 81 continues to move toward the workstation, and the positioning telescopic shaft 82 retracts upward until the arc-shaped portion of the positioning telescopic shaft 82 is located inside the positioning concave shaft 81, at which point the mold frame 6 stops moving. (Reference) Figure 6The support plate 31 is provided with a clearance groove 311. The clearance groove 311 is used to provide clearance space for the positioning telescopic shaft 82 and the positioning concave shaft 81 when the lifting drive mechanism 11 drives the upper plate 12 to lower the support plate 31.

[0024] In a specific embodiment, a mold frame blocking block 15 is also included. The mold frame blocking block 15 is installed on one side of the mold moving track 7. When the mold frame 6 drives the mold to slide to the second position, the mold frame blocking block 15 is located on the side of the mold frame 6 away from the lower plate 13.

[0025] The working process of the automatic separation mechanism between the mold and the frame station proposed in this application is described below.

[0026] During the preparation process, the upper plate 12 is driven by the lifting drive mechanism 11 to move the support component 3, the lifting component 2, the mounting base 5 and the lifting rail 9 upward, and the support plate 31 of the support component 3 is placed in the target position. The distance between the abutting part 231 of the adjusting screw 23 and the extension plate 22 is adjusted to adjust the position of the lifting rail 9 when it stops moving upward, so that the lifting rail 9 is connected with the mold transfer rail 7 located on one side of the lower plate 13.

[0027] During the descent of the upper platen 12, the mold frame 6 and the mold within the mold frame 6 slide from the mold transfer track 7 to the lifting track 9, bringing the mold into the workstation above the frame 1. Then, the lifting and moving drive mechanism drives the upper platen 12 to move toward the lower platen 13, and drives the mounting plate 21, mounting seat 5, lifting track 9, mold frame 6, and mold of the lifting assembly 2 to move downward until the mounting seat 5 is located on the frame fixing plate 14. The lifting assembly 2 then stops descending. At this point, the adjusting screw 23 of the lifting assembly 2 separates from the support plate 31, and the lifting track 9 is offset from the mold transfer track 7. The upper platen 12 continues to move toward the lower platen 13 until it presses down onto the mold, clamping the mold between the upper platen 12 and the lower platen 13, and executing the process corresponding to the workstation.

[0028] During the rising and demolding process of the upper platen 12, after the workpiece in the station is completed, the lifting drive mechanism 11 drives the upper platen 12 to rise. After the support plate 31 abuts against the adjusting screw 23, the upper platen 12 continues to rise, which will drive the lifting assembly 2, the mounting base 5, the lifting rail 9, the mold frame 6, and the mold installed in the mold frame 6 to move upward, so that the mold separates from the lower platen 13. The upper platen 12 drives the support plate 31 to move upward to the target position, and the lifting rail 9 rises to the position of docking with the mold transfer rail 7, so that the mold frame 6 and the mold slide from the lifting rail 9 to the mold transfer rail 7 and are moved out of the frame 1.

[0029] The above embodiments are only used to further illustrate the technical solution of this utility model, but this utility model is not limited to the embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of the technical solution of this utility model.
