Description

Technical Field

[0001] This application relates to the field of mold frame technology, and in particular to a novel mold frame. Background Technology

[0002] Mold frames are basic structural components used in industrial production to fix and support molds or tooling fixtures, and are widely used in manufacturing fields such as injection molding, stamping, and casting.

[0003] Traditional mold frames typically employ integral steel plate welding or standard mold frame assembly structures, which suffer from problems such as heavy weight, difficulty in adjustment, and poor versatility.

[0004] Existing mold bases are mostly designed with fixed dimensions, making it difficult to adapt to the rapid changeover requirements of molds of different specifications. Furthermore, they are prone to deformation during long-term use, affecting machining accuracy. With the development of flexible manufacturing, existing mold base structures can no longer meet the requirements for efficient switching between multiple product types and small batch production. To address these issues, a novel mold base is proposed. Utility Model Content

[0005] The purpose of this application is to provide a new type of mold frame, which adopts a modular design and solves the need for rapid mold changeover for different specifications.

[0006] This application provides a novel mold frame with the following technical solution: A novel mold frame includes a base plate assembly, a column assembly, a beam assembly, and a reinforcing assembly. The base plate assembly includes a base plate body, the upper surface of which is provided with a uniformly distributed matrix of holes. The column assembly includes two column bodies, each column body having a connecting base fixedly connected to its bottom end. Each connecting base has a first connecting bolt installed at each of its four corners. Each column body has a sliding groove at its top end, and a slider is slidably connected to the inner wall of each sliding groove. Each slider has a connecting groove on one side, and a locking bolt is threaded to the inner wall of each connecting groove. Each sliding groove has a linear array of positioning holes on its inner wall.

[0007] The crossbeam assembly includes a crossbeam body, with connecting blocks fixedly connected to both sides of the crossbeam body. The dimensions of the connecting blocks are adapted to the dimensions of the connecting grooves, and each connecting block has a through threaded hole on its inner wall. A T-slot is formed on the upper surface of the crossbeam body.

[0008] By adopting the above technical solution, the matrix hole array of the substrate body and the connecting base and first connecting bolt of the column assembly form a modular installation structure, which allows the column body to be installed at different positions in the hole array according to the mold specifications. This solves the problem that the fixed size of the traditional mold frame is difficult to adapt to different molds, realizes the flexible adjustment of the lateral spacing of the mold frame, improves the adaptability of the mold frame to molds of multiple specifications, and the substrate assembly, column assembly and beam assembly are all modularly connected. If a part is damaged, the module can be replaced individually, reducing maintenance costs.

[0009] Preferably, the matrix aperture array covers the entire effective bearing area of ​​the substrate assembly, and the column body is installed inside the matrix aperture array via a connecting base and a first connecting bolt.

[0010] By adopting the above technical solution, the matrix hole array fully covers the effective load-bearing area of ​​the substrate assembly, ensuring that the column assembly can withstand the mold load when installed at any hole position. This avoids the problem of uneven load-bearing caused by the limited installation position of traditional mold frames. At the same time, the stability and reliability of the column body installation are enhanced by fixing the connecting base and the first connecting bolt.

[0011] Preferably, the substrate body has pre-drilled holes at all four corners.

[0012] By adopting the above technical solution, the reserved holes at the corners of the substrate body can be used to fix the whole to the equipment workbench or to install auxiliary positioning components, which solves the problem of lack of fixed interface when installing traditional mold frame, and improves the convenience of connecting the mold frame to external equipment and the installation accuracy.

[0013] Preferably, a limiting guide rail is fixedly connected to the inner wall of each of the slide grooves, and a limiting groove is formed on the other side of each of the sliders. The slider is slidably sleeved on the outer surface of the limiting guide rail through the limiting groove.

[0014] By adopting the above technical solution, the limiting guide rail in the slide and the limiting groove of the slider form a sliding guide structure, which keeps the slider stable when adjusting the height and avoids shaking. This solves the problem of accuracy deviation caused by structural looseness during traditional mold frame adjustment and improves the stability and reliability of mold frame height adjustment.

[0015] Preferably, the crossbeam body is installed between two sliders via a connecting block, a connecting groove, and a locking bolt, with the locking bolt threaded inside the connecting block.

[0016] By adopting the above technical solution, the connecting block of the crossbeam body and the connecting groove of the slider are connected by locking bolts, realizing stepless adjustment of the crossbeam height. When it is necessary to change the mold of different thickness, simply loosen and remove the locking bolts to slide the crossbeam body up and down. This solves the problem that the fixed height of the traditional mold frame is difficult to adapt to different molds, and greatly improves the mold frame changeover efficiency.

[0017] Preferably, the interior of the crossbeam body has evenly distributed mounting holes, each mounting hole having a through T-slot, and a second connecting bolt is installed on the inner wall of the mounting hole.

[0018] By adopting the above technical solution, the T-slots on the crossbeam body, together with the mounting holes and the second connecting bolts, can quickly install various fixtures, solving the problems of cumbersome installation and poor versatility of traditional mold frame fixtures, realizing the fixation and convenience of the mold, while the evenly distributed mounting holes ensure the uniform transmission of mold load.

[0019] Preferably, two connecting iron plates are welded to the outer surface of each column body, and the reinforcing component includes two triangular reinforcing ribs, which are respectively installed on both sides of the two column bodies.

[0020] By adopting the above technical solution, the welding of the connecting iron plates facilitates the subsequent installation of the triangular reinforcing ribs.

[0021] Preferably, each of the four corners of the triangular reinforcing rib is equipped with a third connecting bolt, and the triangular reinforcing rib is reinforcedly connected to the base plate body and the column body through the third connecting bolt, connecting iron plate and matrix hole array.

[0022] By adopting the above technical solution, the triangular reinforcing ribs are connected to the matrix hole array of the connecting iron sheet and the base plate body through the third connecting bolt, forming a multi-angle support structure, which further disperses the force on the mold frame, avoids local stress concentration, solves the deformation problem caused by insufficient structural strength of traditional mold frames, and ensures the stability of the processing accuracy of the mold frame in long-term use.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] This novel mold frame utilizes a modular installation structure formed by the matrix hole array of the base plate body, the connecting base of the column assembly, and the first connecting bolt. This allows for flexible adjustment of the lateral spacing of the column bodies, and stepless adjustment of the beam body height via sliding grooves, sliders, and locking bolts. Furthermore, the beam body and column bodies can be flexibly disassembled and reassembled, enabling the replacement of the beam body and solving the problem of traditional mold frames having fixed dimensions that are difficult to adapt to different molds. The sliding guide structure of the limiting guide rail and limiting groove enhances the adjustment stability, and the T-slot and mounting holes enable rapid mold fixation. The use of triangular reinforcing ribs, connecting iron plates, and the third connecting bolt enhances structural rigidity, distributes stress, and prevents deformation. Moreover, each module is detachable, and damaged parts can be replaced individually, reducing maintenance costs. Attached Figure Description

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0033] Example 1: A novel mold frame includes a base plate assembly 1, a column assembly 2, a crossbeam assembly 3, and a reinforcing assembly 4. The base plate assembly 1 includes a base plate body 101, the upper surface of which is provided with a uniformly distributed matrix of holes 102. Pre-drilled holes 103 are provided at each of the four corners of the base plate body 101. These pre-drilled holes 103 can be used to fix the entire assembly to the equipment workbench or to install auxiliary positioning components, solving the problem of lack of fixing interfaces during traditional mold frame installation and improving the convenience and installation accuracy of connecting the mold frame to external equipment. The column assembly 2 includes two column bodies 201, each column body 201 having a fixed bottom end... The base is fixedly connected to a connecting base 202, and a first connecting bolt 203 is installed at each of the four corners of the connecting base 202. The matrix hole array 102 covers the entire effective load-bearing area of ​​the substrate assembly 1. The column body 201 is installed inside the matrix hole array 102 through the connecting base 202 and the first connecting bolt 203. The matrix hole array 102 fully covers the effective load-bearing area of ​​the substrate assembly 1, ensuring that the column assembly 2 can withstand the mold load when installed at any hole position. This avoids the problem of uneven load-bearing caused by the limited installation position of traditional mold frames. At the same time, the stability and reliability of the installation of the column body 201 are enhanced by the fixing of the connecting base 202 and the first connecting bolt 203.

[0034] Each column body 201 has a groove 204 at its top, and a slider 206 is slidably connected to the inner wall of each groove 204. A limit guide rail 205 is fixedly connected to the inner wall of each groove 204. A limit groove 207 is opened on the other side of each slider 206. The slider 206 is slidably sleeved on the outer surface of the limit guide rail 205 through the limit groove 207. The limit guide rail 205 in the groove 204 and the limit groove 207 of the slider 206 form a sliding guide structure, which keeps the slider 206 stable when adjusting the height and avoids shaking. This solves the problem of accuracy deviation caused by structural looseness during traditional mold frame adjustment and improves the stability and reliability of mold frame height adjustment. A connecting groove 208 is opened on one side of each slider 206, and a locking bolt 209 is threadedly connected to the inner wall of each connecting groove 208. A linear array of positioning holes 210 is opened on the inner wall of each groove 204.

[0035] Example 2: A novel mold frame, based on the same concept as Example 1 above, this example proposes a crossbeam assembly 3 including a crossbeam body 301. Connecting blocks 302 are fixedly connected to both sides of the crossbeam body 301. The dimensions of the connecting blocks 302 are adapted to the dimensions of the connecting grooves 208, and each connecting block 302 has a through threaded hole on its inner wall. A T-slot 303 is formed on the upper surface of the crossbeam body 301. The crossbeam body 301 is installed between two sliders 206 via the connecting blocks 302, connecting grooves 208, and locking bolts 209. Simultaneously, the locking bolts 209 are threaded into the interior of the connecting blocks 302. The connecting blocks 302 of the crossbeam body 301 are connected to the connecting grooves 208 of the sliders 206 via the locking bolts 209, achieving stepless adjustment of the crossbeam height. When different... When using thick molds, simply loosen and remove the locking bolt 209 to slide the crossbeam body 301 up and down. This solves the problem that the fixed height of traditional mold frames is difficult to adapt to different molds, greatly improving the mold frame changeover efficiency. The crossbeam body 301 has evenly distributed mounting holes 304 inside, each mounting hole 304 is penetrated by a T-slot 303, and a second connecting bolt 305 is installed on the inner wall of the mounting hole 304. The T-slot 303 on the crossbeam body 301 cooperates with the mounting hole 304 and the second connecting bolt 305 to quickly install various fixtures. This solves the problem of cumbersome installation and poor versatility of traditional mold frame fixtures, realizing mold fixing and convenience. At the same time, the evenly distributed mounting holes ensure the uniform transmission of mold load. Two connecting iron plates 211 are welded to the outer surface of each column body 201.

[0036] The reinforcing component 4 includes two triangular reinforcing ribs 401, which are respectively installed on both sides of the two column bodies 201. The connecting iron plates 211 welded together facilitate the subsequent installation of the triangular reinforcing ribs 401. Each triangular reinforcing rib 401 has a third connecting bolt 402 installed at each of its four corners. The triangular reinforcing ribs 401 are reinforcedly connected to the base plate body 101 and the column body 201 through the third connecting bolts 402, the connecting iron plates 211, and the matrix hole array 102. The triangular reinforcing ribs 401 are connected to the connecting iron plates 211 and the matrix hole array 102 of the base plate body 101 through the third connecting bolts 402, forming a multi-angle support structure. This further disperses the stress on the mold frame, avoids local stress concentration, solves the deformation problem caused by insufficient structural strength of traditional mold frames, and ensures the stability of the processing accuracy of the mold frame during long-term use.

[0037] The implementation principle of this application embodiment is as follows: First, the column body 201 is installed on the substrate body 101 using the connecting base 202 and the first connecting bolt 203 at the bottom of the column assembly 2 through the uniformly distributed matrix hole array 102 on the substrate body 101. Different positions in the hole array can be selected for installation according to the mold specifications, achieving flexible adjustment of the lateral spacing of the mold frame. In the sliding groove 204 at the top of the column body 201, the slider 206 slides on the limiting guide rail 205 through the limiting groove 207. When the height of the crossbeam needs to be adjusted, the locking bolt 209 is loosened, and the slider 206 can slide up and down in the sliding groove 204. The connecting blocks 302 on both sides of the crossbeam body 301 are inserted into the connecting groove 208 of the slider 206, and then the locking bolt 209 is inserted into the corresponding positioning hole 210 for threaded connection and fixation, thereby achieving stepless adjustment of the height of the crossbeam body 301. The T-slot 303 on the upper surface of the crossbeam body 301, in conjunction with the internal mounting holes 304 and the second connecting bolt 305, allows for the quick installation of various fixtures, fixing the mold onto the crossbeam assembly 3. The connecting iron plate 211 welded to the outer surface of the column body 201 is connected to the triangular reinforcing rib 401 via the third connecting bolt 402. Simultaneously, the triangular reinforcing rib 401 is also connected to the matrix hole array 102 of the base plate body 101 via the third connecting bolt 402, forming a multi-angle support structure that distributes stress, enhances structural rigidity, and prevents deformation caused by localized stress concentration. The pre-drilled holes 103 at the four corners of the base plate body 101 allow for the entire assembly to be fixed to the equipment workbench or for the installation of auxiliary positioning components. When a component of the mold frame is damaged, due to the modular connection between components, the damaged module can be replaced individually, reducing maintenance costs and meeting the efficient switching requirements of multi-variety, small-batch production.
