Description

Technical Field

[0001] This utility model relates to the field of mold base technology, specifically a mold base structure that allows for quick mold replacement. Background Technology

[0002] The mold base structure is the base part in the mold used to support and fix the core components of the mold. Its main function is to provide a stable foundation for the mold, ensure accurate alignment and evenly distribute the pressure during the molding process, prevent deformation or displacement, thereby ensuring the dimensional accuracy and molding quality of the product, and extending the service life of the mold.

[0003] However, traditional mold bases rely on manual adjustment of the mold position, which is cumbersome and prone to human error, making it difficult to guarantee consistent positioning. Furthermore, existing technologies often use dispersed locking points for mold fixing, which can easily cause mold skewing due to differences in locking sequence or force, affecting processing accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A mold base structure for quick mold replacement includes a base with four guide grooves at its four corners. These guide grooves are used to engage with guide posts of external equipment for guiding. Multiple fixing holes are located on the side of the base adjacent to the guide grooves for fixing the base to an external support device. An assembly groove is located on the side of the base adjacent to the fixing holes, with four assembly screw holes at its four corners. An assembly mechanism is bolted into the assembly groove, and the outer circumferential surface of the assembly mechanism is clearance-fitted with the inner wall of the assembly groove, enabling quick mold positioning and replacement.

[0010] Preferably, two locking screw holes are symmetrically opened on both sides of the top of the sliding block, and the locking screw holes are used for bolts to pass through so that the sliding block is fixed to the mold.

[0011] Preferably, a positioning groove is provided at the top of the sliding block between two locking screw holes, and a positioning pin for the mold passes through the positioning groove to realize the positioning and installation of the sliding block and the mold.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This mold base structure with quick mold replacement achieves rapid mold positioning and automatic correction through the precise guiding fit of sliding block and sliding groove, and the self-centering structure of positioning pin and positioning groove, which significantly shortens mold replacement time and reduces the traditional manual repeated measurement and adjustment process.

[0014] 2.

[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.

[0021] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0022] A mold base structure for quick mold replacement includes a base 101. Four guide grooves 102 are formed at the four corners of the base 101. These guide grooves 102 are used to connect with guide posts of external equipment for guiding. Multiple fixing holes 103 are formed on the side of the base 101 adjacent to the guide grooves 102. These fixing holes 103 are used to fix the base 101 to an external support device. An assembly groove 104 is formed on the side of the base 101 adjacent to the fixing holes 103. Four assembly screw holes 105 are formed at the four corners of the assembly groove 104. An assembly mechanism 106 is bolted into the assembly groove 104. The outer circumferential surface of the assembly mechanism 106 is clearance-fitted with the inner wall surface of the assembly groove 104 to achieve quick mold positioning and replacement.

[0023] The above scheme enables the guide groove to guide the guide column of the external equipment, the fixing hole to fix the base to the external support device, the assembly groove to install and position the assembly mechanism, the assembly screw hole to connect the assembly screw, and the clearance fit between the assembly mechanism and the assembly groove to achieve the core function of quick positioning and replacement of the mold.

[0024] In this embodiment, preferably, the assembly mechanism 106 includes an assembly block 107, which is embedded in the assembly slot 104, and the assembly block 107 has four assembly holes 108 at its four corners.

[0025] The above scheme enables the main support of the assembly mechanism through the assembly block, the through-installation of the assembly screw through the assembly hole, and the modular assembly function of quick assembly and disassembly through the embedded installation structure of the assembly block and the assembly slot.

[0026] In this embodiment, preferably, an assembly screw 109 is installed through the assembly hole 108, and the end of the assembly screw 109 is screwed into the assembly screw hole 105 by thread, thereby fixing the assembly block 107 in the assembly groove 104.

[0027] The above scheme achieves rigid fixation between the assembly block and the base through the threaded insertion of the assembly screw, and the mechanical transmission of preload is achieved through the threaded connection structure at the end of the screw.

[0028] In this embodiment, preferably, the assembly block 107 has a plurality of sliding grooves 110 on the side adjacent to the assembly hole 108, and a sliding block 111 is slidably disposed in the sliding groove 110.

[0029] The above scheme achieves the guiding sliding function of the sliding block through the sliding groove, the stepless adjustment of the mold position through the free sliding state of the sliding block in the sliding groove, and the minimization of movement resistance through the precision-machined surface of the sliding groove.

[0030] In this embodiment, preferably, two locking screw holes 112 are symmetrically opened on both sides of the top of the sliding block 111. The locking screw holes 112 are used for bolts to pass through so that the sliding block 111 is fixed to the mold.

[0031] The above scheme achieves the through-locking effect of the bolt through the locking screw hole, the rigid connection between the sliding block and the mold is achieved through the axial preload of the bolt, and the stable fixing effect with balanced force is achieved through the symmetrically distributed locking screw hole structure on both sides.

[0032] In this embodiment, preferably, the top of the sliding block 111 is provided with a positioning groove 113 between the two locking screw holes 112, and a positioning pin for the mold passes through the positioning groove 113 to realize the positioning and installation of the sliding block 111 and the mold.

[0033] The above scheme achieves the insertion and guiding function of the mold positioning pin through the positioning groove, the initial positioning function of the mold through the geometric matching structure of the positioning pin and the positioning groove, and the sequential synergistic function of positioning and locking through the layout design of the positioning groove between the locking screw holes.

[0034] In this embodiment, the mold base 101 structure with quick mold replacement is used as follows: First, the operator inserts the positioning pin at the bottom of the mold into the positioning groove 113 at the top of the sliding block 111, forming an initial guide through the geometric matching of the two. Simultaneously, a bolt is used to pre-connect the mold to the locking screw hole 112. After the pre-connection, the sliding block 111 is inserted into the sliding groove 110, allowing it to slide freely within the groove. Then, the operator pushes the mold, causing the sliding block 111 to move laterally. The precision sliding pair between the sliding groove 110 and the sliding block 111 automatically corrects the mold's center position. Once the mold reaches the target station, the assembly block 107 is embedded into the base. The assembly slot 104 of 101 generates a uniform radial constraint force by screwing the four corner assembly screws 109 into the screw holes of the base 101, forcing the assembly block 107 to form a stable fit with the inner wall of the assembly slot 104. At this time, the degree of freedom of movement of the sliding block 111 in the sliding groove 110 is rigidly restricted. Finally, the locking bolts on both sides of the sliding block 111 are tightened. The axial clamping force generated by the bolts causes the contact surface between the sliding block 111 and the sliding groove 110 to form static friction, completely eliminating the assembly gap. The whole process, through the coordinated mechanism of "sliding adjustment - rigid limit - friction locking", enables the mold to be quickly positioned and replaced without the use of external measuring tools, and the repeatability of the positioning accuracy meets the equipment processing requirements.
