Description

Technical Field

[0001] This application relates to the field of mechanical manufacturing technology, and in particular to a press mold adapter. Background Technology

[0002] In applications where industrial equipment such as presses connects to molds, traditional mold-press adapter structures mostly use bolt locking. A typical structure involves inserting the mold adapter pin into the press adapter's inner hole, and then tightening the mold by screwing in locking bolts from the side. From an operational perspective, each mold installation or removal requires tightening or loosening multiple bolts individually, significantly extending mold changeover time and severely reducing production efficiency. Furthermore, during mold changeover operations, one person often needs to lift the mold's upper platen, precisely insert the mold positioning pin into the press adapter, and maintain a tight fit between the pin and the adapter, while another person must simultaneously screw the locking bolts into the adapter from the side and tighten them. This operational mode not only further reduces mold changeover efficiency but also poses significant safety hazards.

[0003] Regarding alignment accuracy, the alignment of locking bolts relies entirely on manual adjustment, which is difficult and time-consuming, directly affecting installation accuracy and repeatability. This can lead to uneven stress on the mold or equipment, thus adversely affecting processing quality. As for the control of preload, the reliability of bolt connections is highly dependent on the precise control of preload. Insufficient preload will cause the connection to loosen, while excessive preload may cause bolt elongation, thread stripping, or damage to the contact surface, making the connection reliability extremely unstable. In environments with high vibration and impact, such as presses, the connection is prone to loosening, posing serious safety hazards and potentially damaging the threads or connection surfaces.

[0004] In addition, bolts are prone to loosening due to vibration during equipment operation, requiring regular inspection and retightening, which increases downtime and maintenance time and costs. If the loosening is not dealt with in time, it may cause safety accidents or damage to equipment and molds. Utility Model Content

[0005] This application provides a press mold adapter to solve the problems of low mold replacement efficiency, difficulty in ensuring alignment accuracy, and poor connection reliability that exist when the traditional press mold and equipment are connected by bolt locking.

[0006] This application provides a press mold adapter, including: a mold end adapter, an equipment end adapter post, and a base plate;

[0007] The mold end adapter is composed of a narrow top and a wide bottom, forming a T-shaped groove;

[0008] The adapter post at the device end is provided with a boss that matches the shape of the groove;

[0009] The mold end adapter and the equipment end adapter are embeddedly connected through the cooperation of the groove and the boss;

[0010] The mold end adapter is provided with a waist-shaped groove and a base. The waist-shaped groove and the base cooperate with each other to connect the mold end adapter and the equipment end adapter and fix them on the base plate.

[0011] Optionally, the orientation of the base is perpendicular to the connection direction of the mold end adapter and the equipment end adapter.

[0012] Optionally, the base is provided with a first waist-shaped groove and a second waist-shaped groove;

[0013] The first waist-shaped groove is disposed at one end of the base;

[0014] The second waist-shaped groove is located at the other end of the base.

[0015] Optionally, the adapter further includes a first bolt and a second bolt;

[0016] The first bolt is adapted to the first slot, and the second bolt is adapted to the second slot;

[0017] The first bolt passes through the first waist-shaped groove and is fixedly connected to the base plate;

[0018] The second bolt passes through the second waist-shaped groove and is fixedly connected to the base plate.

[0019] Optionally, the mold end adapter further includes a gasket, which is disposed between the first bolt and the second bolt.

[0020] Optionally, the bottom width of the groove of the mold end adapter is 26mm; the top width of the groove is 16mm.

[0021] Optionally, the bottom height of the groove of the mold end adapter is 10mm; the top height of the groove is 10mm.

[0022] Optionally, the surfaces of the mold end adapter and the equipment end adapter are provided with anti-slip textures.

[0023] As can be seen from the above technical solutions, this application has the following advantages:

[0024] 1. Traditional bolt-locking methods require tightening or loosening multiple bolts individually during mold installation or disassembly, which is cumbersome and time-consuming. The adapter, through the T-shaped groove on the mold end and the protrusion on the equipment end, achieves quick positioning and initial connection, eliminating the need for complex bolt operations, shortening mold changeover time, and improving production efficiency. Furthermore, a single person can complete the mold lifting, positioning, and connection operations, reducing the number of operators, lowering labor costs, and avoiding potential safety hazards associated with multi-person collaborative operations.

[0025] 2. The embedded connection structure of the adapter also enables the mold end adapter and the equipment end adapter to automatically and accurately align, ensuring the accurate installation of the mold on the press, thereby improving the processing quality and reducing product quality problems caused by installation errors.

[0026] 3. The embedded connection of the adapter and the subsequent fixing method through the waist-shaped groove and the base make the connection more stable and reduce the loosening problem caused by vibration. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] Please see Figure 1 , Figure 2 ,as well as Figure 3 , Figure 1 This is a cross-sectional view of the press mold adapter seat. Figure 2 This is a schematic diagram of the die end adapter structure in a press die adapter seat. Figure 3 This is a schematic diagram of the equipment end adapter column in the mold adapter seat of a press machine.

[0037] This application first provides an embodiment of a press mold adapter, which includes: a mold end adapter 1, an equipment end adapter 2, and a base plate 3;

[0038] The mold end adapter 1 is composed of a narrow top and a wide bottom, forming a T-shaped groove;

[0039] The adapter post 2 at the device end is provided with a boss that matches the shape of the groove;

[0040] The mold end adapter 1 and the equipment end adapter 2 are connected by the cooperation of the groove and the boss to achieve an embedded connection;

[0041] The mold end adapter 1 is provided with a waist-shaped groove and a base 101. The waist-shaped groove and the base 101 cooperate with each other to connect the mold end adapter 1 and the equipment end adapter 2 and fix them on the base plate 3.

[0042] The equipment-end adapter post and the equipment-end adapter post are made of alloy steel. The mold-end adapter seat 1 consists of a narrow top and a wide bottom, forming a T-shaped groove. The narrower upper part provides initial guidance during connection, facilitating the smooth entry of the boss of the equipment-end adapter post 2 into the groove; the wider lower part provides stable support and positioning space for the boss, ensuring reliable connection. Simultaneously, the mold-end adapter seat 1 also features a waist-shaped groove and a base 101. The waist-shaped groove facilitates installation and adjustment, allowing operators to fine-tune the position of the mold-end adapter seat 1 within a certain range to adapt to different installation requirements; the base 101 is used to connect and fix to the base plate 3, ensuring the stability of the mold-end adapter seat 1 during operation.

[0043] The adapter post 2 at the equipment end is provided with a boss that matches the shape of the groove in the adapter seat 1 at the mold end. The shape and size of the boss are precisely designed to perfectly fit the T-shaped groove and achieve an embedded connection.

[0044] During operation, the T-shaped groove of the mold-end adapter 1 is aligned with the boss of the equipment-end adapter 2 to achieve an embedded connection. Then, using suitable bolts or other fasteners, the mold-end adapter 1 and the equipment-end adapter 2 are connected and fixed to the base plate 3 via the waist-shaped groove of the mold-end adapter 1 and the base 101. During the connection process, the guiding effect of the T-shaped groove allows the boss to smoothly enter the groove, ensuring a smooth connection. During mold use, this adapter can stably connect the mold and the press equipment, ensuring smooth processing. When mold replacement is required, the reverse sequence of operations allows for quick and safe mold disassembly and replacement.

[0045] In this embodiment, the adapter seat achieves rapid positioning and initial connection through the embedded engagement of the T-shaped groove of the mold-end adapter seat 1 and the boss of the equipment-end adapter post 2, eliminating the need for complex bolt operations, shortening mold changeover time, and improving production efficiency. Furthermore, a single person can complete the mold lifting, positioning, and connection operations, reducing the number of operators, lowering labor costs, and avoiding potential safety hazards associated with multi-person collaborative operations. The embedded connection structure of the adapter seat also enables automatic and precise alignment of the mold-end adapter seat 1 and the equipment-end adapter post 2, ensuring accurate mold installation on the press, thereby improving processing quality and reducing product quality issues caused by installation errors. The embedded connection method of the adapter seat, along with the subsequent fixing method using the waist-shaped groove and the base 101, makes the connection more stable, reducing loosening problems caused by vibration.

[0046] In an optional embodiment, the orientation of the base 101 is perpendicular to the connection direction of the mold end adapter 1 and the equipment end adapter 2.

[0047] In this embodiment, the connection direction of the mold end adapter 1 and the equipment end adapter 2 is the direction in which the boss is embedded in the T-shaped groove. When the mold end adapter 1 and the equipment end adapter 2 are fixed to the base plate 3 by the base 101, the base 101, which is perpendicular to the connection direction, can provide a fastening force from an angle different from the connection direction. In the connection direction, the engagement between the boss and the groove mainly bears the force along the press stamping direction when the mold is working, while the vertical base 101 can effectively resist the lateral force perpendicular to the stamping direction. The two work together to form a stable force-bearing system, which greatly improves the overall stability of the adapter during operation and avoids loosening or displacement caused by uneven force.

[0048] In an optional embodiment, the base 101 is provided with a first waist-shaped groove 102 and a second waist-shaped groove 103; the first waist-shaped groove 102 is provided at one end of the base 101; and the second waist-shaped groove 103 is provided at the other end of the base 101.

[0049] In an optional embodiment, the adapter further includes a first bolt 104 and a second bolt 105; the first bolt 104 is adapted to the first waist-shaped groove 102, and the second bolt 105 is adapted to the second waist-shaped groove 103; the first bolt 104 passes through the first waist-shaped groove 102 and is fixedly connected to the base plate 3; the second bolt 105 passes through the second waist-shaped groove 103 and is fixedly connected to the base plate 3.

[0050] During installation and fixing, after the mold end adapter 1 and the equipment end adapter 2 are embedded and connected through the groove and boss, the first bolt 104 is passed through the first waist-shaped groove 102 at one end of the base 101, and the second bolt 105 is passed through the second waist-shaped groove 103 at the other end of the base 101. The bolts are then tightened and fixed to the base plate 3, thus fixing the mold end adapter 1 to the base plate 3. Regarding position adjustment, the fit between the bolts and the waist-shaped groove provides a reliable guarantee for fine-tuning of the mold end adapter 1. For example, when the press equipment experiences slight displacement due to long-term use, or when adjusting the position is required to replace a mold of different specifications, the operator only needs to loosen the first bolt 104 and the second bolt 105 to move the base 101 along the length of the waist-shaped groove until it reaches the appropriate position, and then retighten the bolts. This adjustment method does not require disassembling the entire adapter, shortening the adjustment time and improving production efficiency.

[0051] The bolts at both ends form a two-point support structure, which, in conjunction with the overall structure of the base 101, can evenly distribute the impact and lateral forces generated during mold operation. The first bolt 104 and the second bolt 105 respectively bear the force at both ends of the base 101, avoiding bolt loosening or deformation of the base 101 caused by force concentration when fixed at a single point. This ensures the structural stability of the adapter under long-term high-intensity operation and extends the service life of the equipment.

[0052] During mold replacement, the base 101 can be separated from the base plate 3 simply by loosening the first bolt 104 and the second bolt 105, without complicated operations. When installing a new mold, the bolts can be quickly positioned and pass through the waist-shaped groove with the help of the guiding effect of the waist-shaped groove, which shortens the operation time of mold replacement.

[0053] In the above-mentioned optional embodiments, the first waist-shaped groove 102 and the second waist-shaped groove 103 are configured to work synergistically with the vertical direction of the base 101, making the connection between the base 101 and the base plate 3 more stable. When the first bolt 104 and the second bolt 105 pass through the first waist-shaped groove 102 and the second waist-shaped groove 103 respectively and are tightened, the fastening force on both ends of the base 101 is evenly distributed, effectively preventing the base 101 from tilting or shaking during operation.

[0054] In an optional embodiment, the mold end adapter 1 further includes a gasket disposed between the first bolt 104 and the second bolt 105.

[0055] The washer is located between the first bolt 104 and the second bolt 105 and is in contact with the upper surface of the base 101. When the first bolt 104 and the second bolt 105 are tightened, the washer disperses the pressure applied by the bolts over a larger area, reducing the pressure per unit area and thus reducing the risk of the base 101 denting or being damaged due to long-term stress. At the same time, this pressure dispersion also makes the stress on the base 101 between the two bolts more even, avoiding local deformation of the base 101 caused by concentrated bolt tightening force, and further enhancing the stability of the connection between the base 101 and the base plate 3.

[0056] In this embodiment, when the mold is working, the impact force of the press is transmitted to the base 101 and the bolts through the adapter. The shim can absorb part of the impact force, reducing the impact load on the bolts and the base 101, thereby extending the service life of the bolts and the base 101. The press generates continuous vibration during operation, which can easily lead to bolt loosening. The shim can impede the rotation of the bolts through surface friction, reducing bolt loosening caused by vibration.

[0057] In an optional embodiment, the bottom width of the groove of the mold end adapter 1 is 26mm; the top width of the groove is 16mm.

[0058] In an optional embodiment, the bottom height of the groove of the mold end adapter 1 is 10mm; the top height of the groove is 10mm.

[0059] In an optional embodiment, the surfaces of the mold end adapter 1 and the equipment end adapter 2 are provided with anti-slip textures.

[0060] In several optional embodiments, the bottom of the T-shaped groove of the mold end adapter 1 is designed to be 26mm wide and 10mm high, while the top is 16mm wide and 10mm high. The difference in width between the top and bottom guides the boss of the equipment end adapter 2. The narrower top first guides the boss to align, while the wider bottom provides sufficient space and a stable support surface. The consistent 10mm height of the top and bottom creates a symmetrical structure in the groove, ensuring uniform force distribution when the boss is embedded and avoiding localized stress concentration. Combined with the width design, this further enhances connection stability. At the same time, the surfaces of the mold end adapter 1 and the equipment end adapter 2 are provided with anti-slip textures, distributed on the inner wall of the groove and the surface of the boss, which increases the friction of the contact surface and effectively prevents relative sliding caused by vibration and impact during press operation.

[0061] It should be noted that the above description of the disclosed embodiments enables those skilled in the art to implement or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
