Description

Technical Field

[0001] This utility model relates to the field of mold frames, and in particular to a mold frame with a stable connection structure. Background Technology

[0002] A mold base, also known as a mold frame, is the basic skeleton of a mold. It is used to fix and support all the components of the mold, ensuring that they can work together precisely during stamping, injection and casting processes. A complete mold base is an integral part of mold production and design.

[0003] The buffer column part of the existing mold frame is generally fixedly connected to the upper mold frame and the lower mold frame. However, after long-term use, the aging of the spring inside the buffer column will affect the normal use of the mold frame. At the same time, when installing the upper mold and the upper mold frame, they are usually installed directly. After long-term use, the mounting holes of the upper mold frame will be damaged, making the mold frame unusable. In addition, the small space between the upper mold frame and the lower mold frame makes the mold very troublesome to install.

[0004] Therefore, those skilled in the art have provided a mold frame with a robust connection structure to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a mold frame with a stable connection structure. The buffer column part of the mold frame can be replaced. At the same time, when installing the upper mold, the fixing mechanism and the upper mold can be installed first, and then the fixing mechanism and the upper fixing frame can be installed.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mold frame with a stable connection structure, including a lower fixing frame, a base plate being threadedly fixed to the lower end face of the lower fixing frame, buffer posts being provided through the four corners of the lower end face of the lower fixing frame, an upper fixing frame being threadedly fixed to the upper end of each of the four buffer posts, a snap-fit ​​groove being provided on both sides of the lower end face of the upper fixing frame, and a placement groove being provided in the middle of the lower end face of the upper fixing frame;

[0007] The upper fixing frame is threaded with a fixing mechanism on its lower end face. Two second through holes are opened on both sides of the upper fixing frame. The fixing mechanism includes a second fixing plate. Two snap-fit ​​plates are fixedly installed on the upper end face of the second fixing plate. Two first fixing holes are opened on one side of each of the two snap-fit ​​plates. Multiple second fixing holes are opened on the lower end face of the second fixing plate.

[0008] Furthermore, the lower end face of the lower fixing frame is provided with a plurality of first connecting holes, and the upper end face of the lower fixing frame is provided with openings on both sides.

[0009] Furthermore, multiple threaded posts are threaded onto both sides of the lower fixing frame, and a second connecting hole is opened on the lower end face of each of the four buffer posts.

[0010] Furthermore, each of the four buffer pillars has a threaded block fixedly installed on its upper end face, and each of the four threaded blocks has a first threaded hole on its upper end face.

[0011] Furthermore, a threaded plate is fixedly provided on the upper end face of the upper fixing frame, and second threaded holes are opened at the four corners of the upper end face of the threaded plate.

[0012] Furthermore, the substrate includes a first fixing plate, with third through holes at the four corners of the lower end face of the first fixing plate, and multiple through holes on the lower end face of the first fixing plate.

[0013] Furthermore, the upper fixed frame has first through holes at the four corners of its upper end face.

[0014] This utility model has the following beneficial effects:

[0015] 1. The present invention proposes a mold frame with a stable connection structure. During use, buffer columns can be placed at the four corners of the lower fixed frame, so that the upper end of the buffer column can pass through the lower fixed frame and connect with the upper fixed frame. The lower end of the lower fixed frame is threaded with a base plate. During use, fixing screws are placed at the four corners of the base plate to fix the buffer column to the upper end of the base plate, so that the buffer column can be indirectly fixed with the lower fixed frame. When the buffer column is damaged during long-term use, it can be easily replaced.

[0016] 2. This utility model proposes a mold frame with a stable connection structure. The lower end of the upper fixed frame is threaded with a fixing mechanism, which can fix the upper mold. The two snap-fit ​​grooves at the lower end of the upper fixed frame can snap with the two snap-fit ​​plates of the fixing mechanism. After snap-fit, fixing screws can be placed inside the second through holes on both sides of the upper fixed frame, so that the fixing screws can be threaded into the first fixing holes of the snap-fit ​​plates, so that the snap-fit ​​plates can be fixed at the lower end of the upper fixed frame, and the fixing mechanism can be firmly fixed at the lower end of the upper fixed frame. When installing the mold, the fixed frame and the mold can be fixed first, and then the fixing mechanism and the upper fixed frame can be fixed, so that the mold can be installed easily, and the fixing mechanism can be easily replaced when damaged.

[0023] 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.

[0024] Reference Figure 1-4 An embodiment of this utility model is provided: a mold frame with a stable connection structure, including a lower fixing frame 1, a base plate 2 is threadedly fixed to the lower end face of the lower fixing frame 1, buffer posts 3 are provided through the four corners of the lower end face of the lower fixing frame 1, an upper fixing frame 8 is threadedly fixed to the upper end of each of the four buffer posts 3, a snap-fit ​​groove 4 is provided on both sides of the lower end face of the upper fixing frame 8, and a placement groove 17 is provided in the middle of the lower end face of the upper fixing frame 8.

[0025] The upper fixed frame 8 has a fixed mechanism 6 threadedly fixed to its lower end face. Two second through holes 14 are opened on both sides of the upper fixed frame 8. Multiple first connecting holes 15 are opened on the lower end face of the lower fixed frame 1. Openings 9 are opened on both sides of the upper end face of the lower fixed frame 1. Multiple threaded posts 10 are threadedly fitted on both sides of the lower fixed frame 1. Two second connecting holes 16 are opened on the lower end face of the four buffer posts 3. Threaded blocks 5 are fixedly installed on the upper end face of the four buffer posts 3. First threaded holes 7 are opened on the upper end face of the four threaded blocks 5. Threaded plates 12 are fixedly installed on the upper end face of the upper fixed frame 8. Second threaded holes 13 are opened at the four corners of the upper end face of the threaded plate 12. First through holes 11 are opened at the four corners of the upper end face of the upper fixed frame 8.

[0026] Specifically, during use, the lower fixing frame 1 can be fixed to the base plate 2 through the first connecting hole 15 at its lower end. The buffer column 3 penetrating through the lower end of the lower fixing frame 1 is fixed to the base plate 2 through the second connecting hole 16, so that the buffer column 3 is indirectly fixed to the lower fixing frame 1, allowing the buffer column 3 to remain stable during use. A threaded block 5 is fixed to the upper end of the buffer column 3. The threaded block 5 can be engaged with the lower end of the upper fixing frame 8 during use, so that the buffer column 3 can buffer when the upper fixing frame 8 moves the mold downward. The upper end of the threaded block 5 has a first threaded hole 7, which can be aligned with the first through holes 11 at the four corners of the upper end of the upper fixing frame 8, and a fixing screw is placed inside. The threaded block 5 and the upper fixing frame 8 can be fixedly connected. The threaded plate 12 at the upper end of the upper fixing frame 8 has a second threaded hole 13, which allows the upper fixing frame 8 to be fixed with other structures. The snap-fit ​​groove 4 at the lower end of the upper fixing frame 8 can snap-fit ​​the fixing mechanism 6. After the fixing mechanism 6 is snapped in, fixing screws can be placed in the second through holes 14 on both sides of the upper fixing frame 8 so that the fixing mechanism 6 can be firmly set at the lower end of the upper fixing frame 8. When the lower fixing frame 1 needs to fix the mold, the threaded columns 10 on both sides can be rotated to fix the mold with threads, so that the mold can remain stable inside the lower fixing frame 1. The opening 9 at the upper end of the lower fixing frame 1 facilitates the snap-fit ​​of the mold.

[0027] Reference Figure 3 The substrate 2 includes a first fixing plate 201, with third through holes 202 at the four corners of the lower end face of the first fixing plate 201, and multiple through holes 203 at the lower end face of the first fixing plate 201.

[0028] Specifically, when in use, the substrate 2 can be fixed to the lower end of the lower fixing frame 1, so that the buffer pillar 3 can be indirectly fixed to the lower fixing frame 1. The main structure of the substrate 2 includes a first fixing plate 201. The first fixing plate 201 can be fixed by placing fixing screws inside the through hole 203 and threading them to the first connecting hole 15 of the lower fixing frame 1, so that the substrate 2 is fixed to the lower end of the lower fixing frame 1. The third through holes 202 opened at the four corners of the lower end of the first fixing plate 201 can be used to place fixing screws inside, so that the fixing screws can be threaded to the second connecting hole 16 opened at the lower end of the buffer pillar 3, so that the buffer pillar 3 can be fixed to the upper end of the substrate 2.

[0029] Reference Figure 3 The fixing mechanism 6 includes a second fixing plate 601. Two snap-fit ​​plates 602 are fixedly installed on the upper end surface of the second fixing plate 601. Two first fixing holes 603 are opened on one side of each snap-fit ​​plate 602. Multiple second fixing holes 604 are opened on the lower end surface of the second fixing plate 601.

[0030] Specifically, during use, the fixing mechanism 6 can be installed with the mold first, and then the fixing mechanism 6 can be fixed with the upper fixing frame 8. The main structure of the fixing mechanism 6 includes a second fixing plate 601. Two snap-fit ​​plates 602 are fixed on the upper end of the second fixing plate 601, which can snap-fit ​​with the snap-fit ​​groove 4 of the upper fixing frame 8. The first fixing hole 603 of the snap-fit ​​plate 602 facilitates the connection with the fixing screw inserted into the upper fixing frame 8 through the second through hole 14, so that the snap-fit ​​plate 602 can remain stable inside the upper fixing frame 8. The second fixing hole 604 of the second fixing plate 601 can be connected with the mold.

[0031] Working principle: When the lower fixing frame 1 needs to fix the mold, the threaded columns 10 on both sides can be rotated to fix the mold with threads, so that the mold can remain stable inside the lower fixing frame 1.

[0032] The fixing mechanism 6 can be fixed to the mold first and then connected to the upper fixing frame 8. The snap-fit ​​groove 4 opened at the lower end of the upper fixing frame 8 can snap the fixing mechanism 6. After the fixing mechanism 6 is snapped in, fixing screws can be placed inside the second through holes 14 on both sides of the upper fixing frame 8 so that the fixing mechanism 6 can be firmly set at the lower end of the upper fixing frame 8.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
