Description

Technical Field

[0001] This application relates to the field of mold technology, and more specifically, to a mold with convenient positioning and installation functions. Background Technology

[0002] In modern manufacturing, molds are essential tools for producing various parts and products, and are widely used in the automotive, electronics, and machinery industries. The installation and positioning of molds are crucial, as their efficiency and quality directly impact production efficiency and product quality.

[0003] Currently, the installation of traditional molds often relies on repeated manual adjustments. This not only increases the labor intensity of operators but also easily leads to positioning errors due to human error. For example, the installation of injection molds requires manual adjustment of the position and locking the mold, a time-consuming and labor-intensive process. Insecure locking can also cause mold displacement, affecting product quality. Therefore, traditional mold installation generally suffers from difficulties in positioning and cumbersome adjustments, resulting in long installation times and large errors. Utility Model Content

[0004] To overcome the above deficiencies, this application provides a mold with convenient positioning and installation functions to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] A mold with convenient positioning and installation function includes a lower mold and an upper mold that matches the lower mold. The lower mold and the upper mold are respectively integrally formed with two positioning components. The two positioning components are respectively placed inside the lower mold frame and the upper mold frame and are fixedly connected to them by two fastening components. The lower mold frame and the upper mold frame are provided with guide components at the four corners of their opposite surfaces.

[0007] Furthermore, the positioning component includes a positioning groove, a positioning block, and two sets of insertion interfaces. The positioning groove is provided on the inner surface of the lower mold frame and the upper mold frame. The positioning block is installed inside the positioning groove. The fixed ends of the lower mold and the upper mold are integrally formed with the positioning block, and two sets of insertion interfaces are respectively provided at both ends of the side wall. The fastening component is inserted inside the two sets of insertion interfaces.

[0008] Furthermore, the lower mold frame includes a lower mold base and two mounting holes. The lower mold base has a positioning groove on its surface and two mounting holes at each end. The fastening components are provided on both sides of the lower mold base surface, and the guide components are welded to the four corners of the surface.

[0009] Furthermore, the upper mold frame includes an upper template and a mold handle. The upper template has a positioning groove at its top and its top end is seamlessly welded to the bottom end of the mold handle. The upper template has fastening components on both sides of its top and its four corners are slidably connected to the guide components.

[0010] Furthermore, the fastening components include two sets of inverted T-shaped dovetail grooves, two sets of fixing blocks, two sets of threaded holes, and two limiting bolts. The surface of the lower mold base and the top sides of the upper mold plate are respectively provided with two sets of inverted T-shaped dovetail grooves and two sets of threaded holes. The bottom ends of the two sets of fixing blocks are respectively slidably engaged with the inside of the two sets of inverted T-shaped dovetail grooves, and the inner ends are respectively connected to the inner pins of the two sets of insertion interfaces. The bottom ends of the two limiting bolts respectively penetrate the surface of the two sets of fixing blocks and are threadedly connected to the inner wall of the two sets of threaded holes.

[0011] Furthermore, the guiding component includes four guide posts and four guide holes. The bottom ends of the four guide posts are respectively welded to the four corners of the lower mold base surface. The upper mold plate has four guide holes at the four corners of the top. The inner walls of the four guide holes are slidably connected to the outer walls of the four guide posts.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model integrates positioning components into the fixed ends of the lower and upper molds, and correspondingly sets positioning grooves and positioning blocks within the lower mold base and upper mold plate, enabling quick and precise embedding and positioning during mold installation. The mold body only needs to align the positioning block with the inside of the positioning groove for initial positioning, greatly shortening the time for finding and adjusting the alignment position and improving installation efficiency.

[0014] 2. The insertion interface on the positioning component of this utility model cooperates with the fastening component to achieve quick locking. After positioning the mold, the operator only needs to insert the fixing block into the insertion interface and then tighten the limit bolt to complete the fastening. The process is simple and quick, reducing tedious adjustment and tightening steps and lowering the labor intensity of the operator.

[0015] 3. The fastening component of this utility model adopts an inverted T-shaped dovetail groove and a sliding engagement structure with the fixing block. This not only facilitates alignment and insertion but also provides good lateral limiting, preventing the fixing block from shifting during insertion or under stress. Combined with the locking of the threaded hole and the limiting bolt, this ensures a very stable and reliable connection between the mold and the mold frame, preventing loosening.

[0016] 4. The guide posts at the four corners of the lower mold frame and the guide holes of the upper mold plate form a sliding guide pair, which ensures that the relative movement of the upper and lower mold frames is stable and precise during the mold closing and opening process, reduces impact and off-center load, and helps to improve the life of the mold and the consistency of the quality of the molded products.

[0017] 5. The mold structure of this utility model is clear, and the function of each component is well-defined. The design of the positioning component, fastening component, and guiding component makes the installation, disassembly, replacement, and maintenance of the mold more convenient. For example, when replacing a worn mold body, the fastening component can be quickly loosened, the guiding component can be used to smoothly move the old mold out, and then the new mold can be quickly installed and positioned and fastened, reducing equipment downtime.

Detailed Implementation

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0029] Example:

[0030] Please see Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 A mold with convenient positioning and installation function includes a lower mold 1 and an upper mold 2 that matches the lower mold 1.

[0031] The lower die 1 and upper die 2 are used for stamping products. The lower die 1 is designed to form the bottom of the product cavity, while the upper die 2 matches the lower die 1 to form the top of the cavity. A positioning component 3 is integrally formed on the end face of the fixing plate of the lower die 1; similarly, a symmetrical positioning component 3 is also integrally formed on the end face of the fixing plate of the upper die 2. The design of these two positioning components 3 is key to achieving fast and precise installation.

[0032] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 A mold with convenient positioning and installation function includes a lower mold 1 and an upper mold 2, each with two integrally formed positioning components 3. The fixed ends of the two positioning components 3 are respectively placed inside the lower mold frame 4 and the upper mold frame 5, and are fixedly connected to them by two fastening components 6. Guide components 7 are provided at the four corners of the opposite surfaces of the lower mold frame 4 and the upper mold frame 5. The positioning components 3 include positioning grooves 31, positioning blocks 32, and two sets of insertion interfaces 33; the lower mold frame 4 includes a lower mold base 41 and two mounting holes 42; the upper mold frame 5 includes an upper template 51 and a mold handle 52; the fastening components 6 include two sets of inverted T-shaped dovetail grooves 61, two sets of fixing blocks 62, two sets of threaded holes 63, and two limit bolts 64; the guide components 7 include four guide posts 71 and four guide holes 72.

[0033] The positioning component 3 is used to achieve rapid and precise mold installation. The positioning component 3 is not a single element, but rather a series of collaborative structural features integrated into the fixed ends of the lower mold 1 and the upper mold 2. Taking the installation of the lower mold 1 as an example: a positioning groove 31 is pre-machined precisely on the surface of the lower mold base 41 of the lower mold frame 4, i.e., the surface in contact with the lower mold 1. The position and size of this positioning groove 31 are strictly determined according to the design of the lower mold 1. The positioning block 32, integrally formed at the fixed end of the lower mold 1, is pressed into the positioning groove 31 through an interference fit. The shape and size of the positioning block 32 are designed to precisely restrict the degrees of freedom of the lower mold 1. Two sets of insertion interfaces 33 are provided at the connection between the lower mold 1 and the positioning block 32; similarly, two sets of insertion interfaces 33 are also provided at the connection between the upper mold 2 and the positioning block 32; this allows the user to use the fastening component 6 to fix the lower mold 1 in the lower mold base 41, and simultaneously fix the upper mold 2 in the upper template 51. When installing the lower mold 1, the operator first aligns the positioning block 32 of the lower mold 1 with the positioning groove 31 on the surface of the lower mold base 41 and gently presses it down, causing the fixed end of the positioning block 32 of the lower mold 1 to engage in the positioning groove 31. At this point, the lower mold 1 has been accurately pre-positioned. Then, the lower mold 1 is fixed to the lower mold base 41 using the fastening component 6. Similarly, when installing the upper mold 2 at the top of the upper mold frame 5 using the positioning component 3, the operator first aligns the positioning block 32 of the upper mold 2 with the positioning groove 31 at the top of the upper mold plate 51 and gently pushes it in, causing the fixed end of the positioning block 32 of the upper mold 2 to engage in the positioning groove 31. At this point, the upper mold 2 has been accurately pre-positioned. Then, the upper mold 2 is fixed to the top of the upper mold frame 5 using the fastening component 6. Through this design, the positioning component 3 effectively achieves rapid alignment and reliable fixing of the mold, greatly simplifying the installation process and improving installation accuracy and efficiency.

[0034] The lower mold base 4 is the basic structure supporting the lower mold 1 and an important component of the overall mold positioning and guiding system. The lower mold base 4 mainly consists of a lower mold seat 41 and two mounting holes 42. The lower mold seat 41 is typically made of high-strength steel through precision machining. The surface of the lower mold seat 41, which contacts the lower mold 1 and supports its weight, needs sufficient flatness and hardness. A positioning groove 31 is precisely formed on the surface of the lower mold seat 41. The position of this positioning groove 31 is determined according to the design requirements of the entire mold system. It is used to accommodate and cooperate with the positioning block 32 on the fixed end of the lower mold 1, thereby achieving rapid and precise positioning of the lower mold 1. The size and shape of the positioning groove 31 must precisely match the positioning block 32 on the fixed end of the lower mold 1 to ensure positioning accuracy and stability. Two mounting holes 42 are formed at both ends of the surface of the lower mold seat 41. These two mounting holes 42 typically penetrate the upper and lower surfaces of the lower mold seat 41, and their diameter and position are determined according to the position of the screw holes on the worktable of the injection molding machine or other processing equipment. The purpose of mounting holes 42 is to securely fix the entire lower mold frame 4 and the lower mold 1 mounted on it to the worktable of the equipment, preventing displacement during injection molding or stamping processes. Bolts and studs are usually used in conjunction with mounting holes 42 for fixing.

[0035] The upper mold base 5 is the basic structure that supports the upper mold 2 and is responsible for connecting the upper mold 2 to the moving parts of the injection molding machine or stamping machine. It also includes a guiding system that cooperates with the lower mold base 4. The upper mold base 5 mainly consists of two parts: the upper template 51 and the mold handle 52. The upper template 51 is usually made of high-strength steel and precision machined, and its shape matches the lower mold base 41. The inner top surface of the upper template 51, which is the working surface that contacts the upper mold 2 and supports its weight, also needs to have sufficient flatness and hardness. A positioning groove 31 is precisely formed on the inner top surface of the upper template 51. The position of this positioning groove 31 corresponds to the positioning groove 31 on the lower mold base 41. It is used to accommodate and cooperate with the positioning block 32 at the fixed end of the upper mold 2, thereby realizing the rapid and accurate positioning of the upper mold 2. The size and shape of the positioning groove 31 must be precisely matched with the positioning block 32 at the fixed end of the upper mold 2. The top end of the upper template 51 and the bottom end of the mold handle 52 are firmly connected together by seamless welding. The mold shank 52 is a key component connecting the upper mold base 5 to the moving part of the injection molding machine or stamping machine. Its shape and size are usually determined according to the specifications and standards of the equipment used. The top of the mold shank 52 is designed with a flange structure for fixed connection with the telescopic end of the equipment. It can withstand the impact and vibration of the mold during high-speed movement and under stress. The upper mold base 5, through the integrated positioning groove 31, the welded connection with the mold shank 52, the mating structure of the fastening component 6, and the design of the guide hole 72, constitutes a top support unit that can reliably support and fix the upper mold 2, and can precisely match and move smoothly with the lower mold base 4. It is a key component to ensure the overall performance and processing accuracy of the mold.

[0036] The fastening component 6 is a key component for reliably connecting the lower mold 1 and the upper mold 2 to the lower mold base 4 and the upper mold base 5, respectively. The fastening component 6 is not a single part, but a system containing multiple cooperating elements. First, two sets of inverted T-shaped dovetail grooves 61 are pre-formed on the surface of the lower mold base 41 of the lower mold base 4 and on both sides of the top of the upper mold plate 51 of the upper mold base 5. Simultaneously, two sets of threaded holes 63 are also formed on both sides of the surfaces of the lower mold base 41 and the upper mold plate 51. The two sets of fixing blocks 62 are the core movable parts of the fastening component 6. The bottom end of each fixing block 62 is designed to precisely match the shape of the inverted T-shaped dovetail groove 61, allowing it to slide and engage along the track of the inverted T-shaped dovetail groove 61. This dovetail connection method not only provides stable sliding guidance but also effectively prevents the fixing blocks 62 from rotating or dislodging under lateral force. The inner end of the fixing block 62 is designed with a structure that matches the insertion interface 33 on the fixed end of the lower mold 1 and the upper mold 2. The fixing block 62 is connected to the insertion interface 33 by a pin connection. In the actual installation process, the operator first aligns the lower mold 1 or the upper mold 2 with the positioning groove 31 on the mold frame, so that the positioning block 32 on the mold enters the positioning groove 31. Then, the fixing block 62 is pushed so that it slides along the dovetail groove 61 until the inner end of the fixing block 62 is aligned with the insertion interface 33 and inserted. At this time, the fixing block 62 occupies a general position in the dovetail groove 61, but the connection is not yet firm. Finally, the bottom end of the limiting bolt 64 is designed to pass through the pre-drilled hole on the fixing block 62. The operator passes the bottom end of the limiting bolt 64 through the fixing block 62 and then screws it into the preset threaded hole 63. As the limiting bolt 64 is tightened, it moves inward along the threaded hole 63, and its bottom end will generate an inward pushing force on the fixing block 62. This thrust forces the fixing block 62 to move further within the dovetail groove 61 until it is stopped by the end of the dovetail groove 61 or reaches a predetermined position, thus firmly locking the fixing block 62 in the dovetail groove 61. Simultaneously, the limiting bolt 64, through a threaded connection, provides additional axial tightening force to the entire fixing block 62. Through this design, the fastening component 6 not only reliably fixes the mold to the mold frame, preventing loosening or displacement during operation, but also utilizes the guiding effect of the dovetail groove to ensure the accuracy and stability of the fixation. The inverted T-shaped dovetail groove 61 also facilitates the installation and adjustment of the fixing block 62. The entire fastening process is relatively fast and convenient, greatly improving the efficiency of mold installation.

[0037] The guide component 7 is a key component used to guide the movement of the upper mold base 5 to the lower mold base 4, thereby ensuring precise alignment and smooth movement of the lower mold 1 and the upper mold 2 during mold opening and closing. The four guide pillars 71 are typically made of a high-hardness, low-friction material, are cylindrical in shape, and are precision ground to ensure the roundness and surface finish of their outer surfaces. These four guide pillars 71 are symmetrically arranged at the four corners of the lower mold base 41 of the lower mold base 4. To ensure sufficient structural strength and positioning accuracy between the guide pillars 71 and the lower mold base 41, their bottom ends are typically welded to the lower mold base 41. The welding process requires strict control of temperature and deformation to ensure that the axis of the guide pillars 71 is perpendicular to the surface of the lower mold base 41, and that the relative positional accuracy between the four guide pillars 71 is high, thus providing a reliable foundation for subsequent guidance. Corresponding to the guide pillars 71 are four guide holes 72 located at the four corners of the top of the upper mold plate 51 of the upper mold base 5. These guide holes 72 are typically machined into precision cylindrical holes, with their inner walls also precision-machined to match the outer diameter of the guide posts 71. The dimensions of the guide holes 72 are designed to be slightly larger than the diameter of the guide posts 71, forming an appropriate clearance fit. This allows the upper mold plate 51 to slide smoothly on the guide posts 71 while effectively limiting its horizontal displacement. In actual operation, when the telescopic end of the injection molding machine or stamping machine drives the upper mold base 5 downward, the four guide holes 72 on the upper mold plate 51 will respectively fit into the four corresponding guide posts 71 on the lower mold base 41. Due to the precise sliding fit between the guide posts 71 and the guide holes 72, they can guide the upper mold base 5 to move precisely along the axial direction of the guide posts 71, ensuring that the upper mold 2 can close accurately and smoothly with the lower mold 1. At the same time, this guiding structure can also effectively withstand and disperse the lateral forces that may be generated when the mold closes, preventing the mold from being misaligned or damaged due to uneven force, ensuring the stability of mold operation and the processing accuracy of the product.
