Description

Technical Field

[0001] This utility model relates to the field of mold installation technology, and in particular to a quick installation structure for a mold. Background Technology

[0002] In the extrusion production process of plastic profiles, pipes, and other products, the forming die is a key piece of equipment to ensure the accuracy of the product's cross-sectional shape and dimensions. Different forming dies are required to produce products of different specifications.

[0003] Existing mold-making methods typically require hoisting or lifting the heavy mold to the installation position, visually aligning it with multiple bolt holes on the machine, and then inserting and tightening the bolts one by one. This process is cumbersome, consuming significant time and physical effort, and demands a high level of operator skill. Furthermore, because each installation relies on manual alignment, it's difficult to guarantee the repeatability of the mold's positioning accuracy, potentially affecting the consistency of the final product's quality. When frequent mold changes are required, this traditional installation method severely impacts production efficiency.

[0004] Therefore, this application provides a quick-installation structure for molded parts to meet the requirements. Utility Model Content

[0005] The purpose of this application is to provide a quick installation structure for molds, which aims to simplify the installation steps, shorten the mold change time, and improve the installation accuracy and stability of the mold.

[0006] To achieve the above objectives, this application provides the following technical solution: a quick-installation structure for a mold, comprising a mold and a fixed frame. The fixed frame is provided with at least one fixed plate guide groove for initially guiding the mold and at least one locking block limiting groove for precisely positioning the mold. The side wall of the mold is provided with an inner fixed plate that can be slidably inserted into the fixed plate guide groove, and a locking block that can be slidably inserted into the locking block limiting groove. A clamping mechanism for locking the mold is provided above the fixed frame. The clamping mechanism includes a pressure block that can slide along the length of the fixed frame. The pressure block is provided with an adjusting bolt, and the lower end of the adjusting bolt is connected to a pressure plate. The pressure plate is used to press down and fix the mold. This structural combination achieves quick installation and stable locking of the mold.

[0007] Preferably, the opening width of the guide groove of the fixing plate is greater than the opening width of the limiting groove of the card block; this design realizes coarse guidance and fine positioning of the mold, making the installation process smoother and more accurate.

[0008] Preferably, the fixed frame is formed by two sets of clamps connected by at least two parallel connecting rods; the pressure block is provided with a connecting hole and slides through the connecting hole onto the connecting rod located above; this structure ensures the stability of the overall frame and the flexibility of the pressure block position adjustment.

[0009] Preferably, the clamping plate of the fixing frame is provided with through holes for fixing it to the machine body, and bolts for fine-tuning the position of the fixing frame; this facilitates the precise installation of the fixing frame on the equipment.

[0010] Preferably, the mold has symmetrically arranged outer fixing plates on both sides, and the locking block is disposed on the outer fixing plates; this enhances the structural strength of the mold sidewall.

[0011] Preferably, the clamping plate of the fixed frame is provided with a plurality of fixed plate guide grooves and locking block limiting grooves, thereby improving the versatility of the device.

[0012] Preferably, the bottom surface of the pressure plate is a plane for contacting the upper surface of the mold; this ensures uniform application of downward pressure and makes locking more reliable.

[0013] In summary, the technical effects and advantages of this utility model are as follows: In this invention, the traditional and complex bolt-to-hole fastening method is simplified to a two-step operation of "sliding in - pressing down", which greatly shortens the auxiliary time for changing molds and improves production efficiency.

[0014] In this invention, the fixed frame is pre-calibrated on the equipment, and the mold is precisely positioned by the cooperation of the locking block and the limiting groove, which ensures the repeatability of the installation accuracy for each mold change and is conducive to the stability of product quality.

[0015] This invention eliminates the need for tedious hole alignment and multi-point fastening operations, reducing the labor intensity of operators and the reliance on individual skills.

[0016] In this invention, the top-pressing locking method provides strong and uniform pressure, effectively preventing the mold from shifting or floating due to force during production, thus ensuring production stability. Attached Figure Description

Detailed Implementation

[0020] 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. Example

[0021] refer to Figure 1-6 The diagram shows a quick-installation structure for a mold, comprising a mold 4 and a fixing frame 5.

[0022] In one embodiment of this invention, the fixed frame 5 is formed by two sets of vertically arranged clamping plates 51 connected by four horizontal connecting rods 52 to form a stable frame structure. The fixed frame 5 is pre-installed and precisely calibrated on the bottom mold 2 of the machine body 1 through the through holes 54 and nuts 53 on its clamping plates 51, serving as a standardized base for the installation of the mold 4.

[0023] In one embodiment of this invention, each clamping plate 51 has multiple fixing plate guide grooves 56 and locking block limiting grooves 55 formed on its inner sidewall along the insertion direction of the mold 4. In this embodiment, the opening width of the fixing plate guide groove 56 is designed to be greater than the opening width of the locking block limiting groove 55. This design is key to achieving rapid alignment and precise positioning.

[0024] In one embodiment of this invention, an outer fixing plate 41 and an inner fixing plate 43 are symmetrically fixed on both sides of the mold 4. The outer fixing plate 41 is provided with an outwardly protruding locking block 42, while the inner fixing plate 43 is a flat plate structure. The shape and size of the locking block 42 are adapted to the locking block limiting groove 55, and the thickness of the inner fixing plate 43 is adapted to the fixing plate guide groove 56.

[0025] In one embodiment of this work, pressure blocks 57 are slidably mounted on the two connecting rods 52 above the fixed frame 5. The pressure blocks 57 pass through connecting holes 58 on the connecting rods 52, allowing them to slide freely in the axial direction of the connecting rods 52 to accommodate molds 4 of different widths or to move to a position that does not interfere with mold installation. An adjusting bolt 60 is vertically mounted on the top of the pressure block 57, and a pressure plate 59 is connected to the lower end of the adjusting bolt 60. Rotating the adjusting bolt 60 allows the pressure plate 59 to move up and down.

[0026] The working principle of this practical application is as follows: The first step, basic installation and calibration: The fixed frame 5, assembled from the clamping plate 51 and connecting rod 52, is installed onto the bottom mold 2 of the machine body 1 through the through holes 54 and bolts. Its position is then precisely fine-tuned and tightened using adjusting nuts 53. This step only needs to be performed once after the initial installation or equipment maintenance. Simultaneously, the pressure block 57 is installed onto the connecting rod 52 above through its connecting hole 58.

[0027] The second step is mold installation: First, slide the pressure block 57 along the connecting rod 52 to one side, ensuring it does not interfere with the mold 4 to be installed. Then, push the mold 4 into the fixed frame 5 from one end. During the pushing process, the inner fixing plates 43 on both sides of the mold 4 first slide into the wider opening of the fixing plate guide groove 56, providing initial guidance and alignment, so that the operator does not need precise alignment. As the mold 4 continues to be pushed in, the locking block 42 on the outer fixing plate 41 then slides into the narrower opening but tighter fitting locking block limiting groove 55, thereby achieving precise positioning of the mold 4 in both horizontal and vertical directions.

[0028] The third step is to lock the mold: After pushing the mold 4 to the predetermined working position, slide the pressure block 57 directly above the mold 4. Then, rotate the adjusting bolt 60 clockwise to move the pressure plate 59 downwards until its bottom surface presses against the upper surface of the mold 4. Continue rotating to apply sufficient preload, thus stably and securely locking the mold 4 onto the fixed frame 5. Finally, connect the wiring between the mold 4 and the controller 3. This completes the entire mold installation process.

[0029] The disassembly process of the mold is the reverse of the above steps. Simply loosen the adjusting bolt 60 counterclockwise and slide the pressure block 57 open to easily pull the mold 4 out of the fixed frame 5.

[0030] The electromechanical connections involved in this utility model are common practices used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments; they are common knowledge.

[0031] Components not described in detail in this article are existing technologies.

[0032] 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.
