Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a quick-locking mechanism for automotive body panel molds. Background Technology

[0002] Automotive body panels are large in size and complex in structure, and the molds used in their production are correspondingly very large and heavy. During the stamping and forming process, the upper and lower molds need to be able to close and lock the mold quickly and frequently.

[0003] In order to ensure that the large upper and lower molds can be accurately aligned during high-speed mold closing and to prevent product defects and mold damage caused by deviation, the existing molds are equipped with a guiding mechanism, which consists of guide pillars set on the mold and guide holes set on the corresponding molds.

[0004] However, existing guiding mechanisms have significant shortcomings in practical use. First, due to the heavy weight of the mold and the fast closing speed, any slight positional deviation of the guide post when it is inserted into the guide hole will cause the end of the guide post to violently impact and chip against the edge of the guide hole. This will not only directly damage the guide post and guide hole, but may even lead to the scrapping of the expensive mold body. Second, as high-frequency moving friction mating parts, the guide post and guide hole will inevitably wear. In many traditional designs, the guide hole is directly machined on the mold body and the guide sleeve is pressed in with an interference fit. Whether it is impact damage or natural wear, once the accuracy of the guide hole decreases, repair is extremely difficult. It is necessary to lift the mold off the production line for complex repairs, or even replace the entire mold component. This results in extremely high maintenance costs, long downtime, and seriously affects production efficiency.

[0005] Therefore, this utility model proposes a quick-locking mechanism for automotive body panel molds to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the quick-locking mechanism for automotive body panel molds, such as difficulty in alignment during high-speed mold closing of large molds, which easily leads to collision damage between guide pillars and guide holes, and difficulty in replacing the guide structure after wear and high maintenance costs, this utility model aims to provide a quick-locking mechanism for automotive body panel molds with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a quick clamping mechanism for automotive body panel molds, comprising: Mold 1, and mold 2 which can move relative to mold 1, wherein the bottom of mold 2 is fixedly connected to a guide post; as well as Guide sleeve and guide slope.

[0008] The mold has a mounting groove on its top, the guide sleeve is fitted into the mounting groove, and the guide sleeve has a mounting hole on its top.

[0009] Furthermore, the guide sleeve is detachably fixed to the mold by bolts passing through the mounting hole. A guide hole is provided through the top of the guide sleeve, and a guide slope is machined at the entrance of the guide hole. The guide slope is a tapered inclined surface surrounding the entrance of the guide hole. The guide post is used to insert into the guide hole when the mold is closed, and automatic alignment is achieved through the guide slope.

[0010] Preferably, the device also includes a base and a bracket, with the mold fixedly connected to the top of the base and the bottom of the bracket fixedly connected to the top of the base. The base and the bracket together form the installation and support frame of the device.

[0011] Preferably, it also includes a hydraulic cylinder, the top fixed end of which is fixedly connected to the top of the bracket. The hydraulic cylinder serves as a power source to provide rapid and powerful clamping pressure.

[0012] Preferably, as a specific installation method, the top of the bracket is provided with a reserved groove, and the top fixed end of the hydraulic cylinder is fixedly connected to the reserved groove. This setting facilitates precise positioning and installation of the hydraulic cylinder and ensures operational stability.

[0013] Preferably, it also includes a locking seat, which is fixedly connected to the bottom output end of the hydraulic cylinder. The locking seat is used to collect and transmit the output force of the hydraulic cylinder to the mold.

[0014] Preferably, the second mold is fixedly connected to the bottom of the locking seat, thereby forming a rigidly connected motion assembly of the hydraulic cylinder, the locking seat and the second mold, ensuring the directness and efficiency of power transmission.

[0015] Preferably, in order to achieve uniformly distributed guidance and locking, the mounting grooves are specifically formed at the top four corners of the mold to provide symmetrical and stable support.

[0016] Preferably, corresponding to the position of the mounting groove, the guide post is specifically fixedly connected to the four corners of the bottom of the mold two to ensure that the four guide points correspond one-to-one with the guide sleeve, so as to achieve smooth insertion and precise guidance.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art that large molds are prone to damage due to collision between the guide post and the guide hole when they are closed at high speed due to the difficulty of alignment. It achieves the effects of automatic guidance alignment, smooth mold closing, and effective protection of mold precision by setting a guide slope at the inlet of the guide hole of the guide sleeve.

[0018] 2. This utility model solves the problem in the prior art that the guide sleeve is integrated with the mold body as a wear part, is difficult to replace after wear, and has high maintenance costs by designing the guide sleeve as an independent component and using mounting grooves and bolts to detachably fix it to the mold. It achieves the effects of convenient maintenance, quick replacement, greatly extending the service life of the mold body and reducing costs.

[0019] 3. This utility model, by using a hydraulic cylinder as a power source and in conjunction with a locking seat and a guide structure of guide pillars and guide sleeves, solves the problems of complex and inefficient mold-locking processes in existing technologies for large molds, and achieves the effects of compact structure, fast mold-locking response speed, large and stable mold-locking force, and high degree of automation.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0023] Please refer to Figures 1 to 4This utility model provides a quick clamping mechanism for automotive body panel molds, which aims to solve the problems of existing automotive body panel molds where alignment difficulties during clamping cause damage to guide pins and guide holes, and high maintenance costs due to the difficulty in replacing worn guide structures.

[0024] like Figure 1 As shown, a quick-locking mechanism for an automotive body panel mold includes a base 1, a mold 2 fixedly connected to the top of the base 1, and a bracket 3 fixedly connected to the bottom of the base 1. Mold 2 serves as a fixed mold, the bracket 3 is used to mount driving components, and mold 6 serves as a movable mold, capable of moving relative to mold 2. A guide post 7 is fixedly connected to the bottom of mold 6. The core of this embodiment lies in the guiding structure between mold 2 and mold 6, specifically: the top of mold 2 has mounting grooves 9, which are specifically located at the four corners of the top of mold 2. Figure 2 and Figure 3 As shown, a guide sleeve 10 is fitted into the mounting groove 9. A mounting hole 12 is provided at the top of the guide sleeve 10. The guide sleeve 10 is fixed to the mold 2 by bolts 13 passing through the mounting hole 12. This detachable fixing method allows the guide sleeve 10 to be easily replaced after wear. Figure 4 As shown, a guide hole 11 is provided through the top of the guide sleeve 10. The guide hole 11 is used to slide and insert the guide post 7. Correspondingly, the guide post 7 is specifically fixedly connected to the four corners of the bottom of the mold 6. At the entrance of the guide hole 11, that is, the top surface of the guide sleeve 10, a guide slope 8 is processed. The guide slope 8 is a conical slope that surrounds the entrance of the guide hole 11. It is used to guide the end of the guide post 7 to automatically align and smoothly slide into the guide hole 11 when the mold 6 falls.

[0025] like Figure 1 As shown, it also includes a power and support structure for driving the movement of mold 2 6. The structure includes a bracket 3, a hydraulic cylinder 4, and a locking seat 5. The bottom of the bracket 3 is fixedly connected to the top of the base 1 for mounting and supporting the hydraulic cylinder 4. A reserved groove is opened on the top of the bracket 3, and the top fixed end of the hydraulic cylinder 4 is fixedly connected to the reserved groove. The bottom output end of the hydraulic cylinder 4 is fixedly connected to the locking seat 5. The bottom of the locking seat 5 is fixedly connected to mold 2 6, so that the hydraulic cylinder 4, the locking seat 5, and the mold 2 6 form a linked power transmission system. The action of the hydraulic cylinder 4 is directly transmitted to the mold 2 6 through the locking seat 5 to drive the mold 2 6 to reciprocate relative to mold 1 2.

[0026] As a preferred embodiment, such as Figure 1 As shown, it also includes a base 1, with the mold 2 fixedly connected to the top of the base 1, and the base 1 provides the mounting foundation for the entire mechanism; and it also includes a bracket 3, with the bottom of the bracket 3 fixedly connected to the top of the base 1, and the bracket 3 is used to support the power components to be installed later.

[0027] As a preferred embodiment, such as Figure 1 As shown, the top of the bracket 3 is provided with a reserved slot, and it also includes a hydraulic cylinder 4. The top fixed end of the hydraulic cylinder 4 is fixedly connected in the reserved slot, and the hydraulic cylinder 4 serves as a power source to provide clamping pressure.

[0028] As a preferred embodiment, such as Figure 1 As shown, it also includes a locking seat 5, which is fixedly connected to the bottom output end of the hydraulic cylinder 4 to transmit the output force of the hydraulic cylinder 4; and the mold 2 6 is fixedly connected to the bottom of the locking seat 5, so that the locking seat 5 can drive the mold 2 6 to move synchronously.

[0029] As a preferred embodiment, such as Figure 1 and Figure 4 As shown, in order to achieve stable and evenly distributed guidance, a plurality of mounting slots 9 are provided on the top of mold 2, and these mounting slots 9 are specifically provided at the four corners of the top of mold 2.

[0030] As a preferred embodiment, such as Figure 1 As shown, in order to match the mounting slots 9 at the four corners, a plurality of guide posts 7 are fixedly connected to the bottom of the mold 2 6. These guide posts 7 are specifically fixedly connected to the four corners of the bottom of the mold 2 6, so as to be inserted into the guide holes 11 of the guide sleeve 10 in a corresponding manner.

[0031] Working principle: During mold locking, the hydraulic cylinder 4 installed on the top of the bracket 3 is activated. The bottom output end of the hydraulic cylinder 4 pushes the fixedly connected locking seat 5. The locking seat 5 drives the fixedly connected mold 2 6 to move downward synchronously. Mold 2 6 can move relative to mold 1 2. During the descent of mold 2 6, the ends of the guide posts 7 at the four corners of the bottom first contact the guide sleeves 10 installed in the four corner mounting grooves 9 at the top of mold 1 2. The guide posts 7 contact the guide slope 8 at the entrance of the guide hole 11 on the guide sleeve 10. With the help of the tapered inclined surface structure of the guide slope 8 surrounding the entrance of the guide hole 11, the guide posts 7 are automatically guided under the downward pressure and smoothly slide into the guide hole 11 of the guide sleeve 10. This process realizes the precise alignment of mold 2 6 with mold 1 2 fixed on the base 1. Subsequently, the hydraulic cylinder 4 continues to apply pressure, and the locking seat 5 presses mold 2 6 and mold 1 2 together, completing the rapid mold locking action. When the guide sleeve 10 wears down due to long-term use, the maintenance process is as follows: The operator only needs to loosen and remove the bolt 13 that passes through the mounting hole 12 to take out the failed guide sleeve 10 from the mounting groove 9 of the mold 12; then fit the new guide sleeve 10 into the mounting groove 9 and fix it again with the bolt 13 through the mounting hole 12 to restore the guiding accuracy of the device. The structural design significantly reduces the difficulty and cost of maintenance.
