Description

Technical Field

[0001] This invention discloses a guiding assembly device for rapid alignment of multi-cavity mold frames, relating to the field of mold frame assembly technology. Background Technology

[0002] Multi-cavity mold bases are the core support structure of injection molds, specifically designed for molding multiple identical plastic parts in a single operation. They typically consist of two main parts: a fixed mold and a moving mold, composed of standardized components such as a faceplate, base plate, guide pillars and bushings, and ejection mechanism, exhibiting high strength, high precision, and high durability. Mold base assembly is the foundation of manufacturing the entire mold. It refers to the precision machining, positioning, assembly, and debugging of the mold base components according to design drawings and technical specifications, ultimately forming a stable and precisely aligned main frame capable of housing cavities, cores, and other molding parts. Assembly quality directly determines the precision, lifespan, and production efficiency of the entire mold, making it a crucial step in mold manufacturing.

Finally, it can be further locked by the bottom locking nut to prevent movement. By adjusting the spiral groove on the outer circumference of the shaft tube in cooperation with the contact block, the extension length of the upper locking mechanism can be adjusted as a whole to adapt to mold frames of different heights, thereby achieving the effect of rapid alignment and guided assembly on different types of multi-cavity mold frames.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Specific implementation examples:

[0028] like Figure 1 As shown, a guide assembly device for rapid alignment of a multi-cavity mold frame includes an upper locking mechanism 1 and a lower locking seat 2.

[0029] The upper locking mechanism 1 and the lower locking seat 2 can cooperate with each other to achieve a locking effect. The lower locking seat 2 is installed at the bottom of the fixed mold, and the upper locking mechanism 1 is installed in the moving mold. The two can play a precise guiding and automatic alignment function. The installation method is as follows: the lower locking seat 2 is first installed in the mounting hole at the bottom of the fixed mold, and then the moving mold is placed on top of the fixed mold. The upper locking mechanism 1 is installed in the corresponding mounting position of the moving mold. After the upper locking mechanism 1 and the lower locking seat 2 perform preliminary positioning, the two lock together to complete the rapid alignment of the moving mold and the fixed mold in the multi-cavity mold frame. On the moving mold, there are multiple modular mold parts to be aligned and installed due to different mold types. Therefore, multiple modular mold parts need to be accumulated on the mounting surface of the top of the moving mold. The upper locking mechanism 1 can then perform positioning and rapid installation. The specific principle is as follows.

[0030] like Figure 2As shown, the lower locking seat 2 includes a base 21, on which several sets of elastic sheet groups 23 are provided. A locking block 24 is installed inside the elastic sheet group 23, and the locking block 24 is fixedly connected to the base 21.

[0031] The main function of the lower locking seat 2 is to provide an initial guiding position for the moving mold and the fixed mold. It is installed by embedding it into the mounting hole at the bottom of the fixed mold. The outer periphery of the base 21 is provided with an elastic sheet group 23, which causes radial shrinkage deformation during the embedding process. After the base 21 is fully embedded, the elastic sheet group 23 returns to its original shape and clamps the inner wall of the mounting hole, thereby realizing the firm fixation and initial positioning guidance of the lower locking seat 2 at the bottom of the fixed mold.

[0032] To ensure good axial stability and radial self-adaptation after the lower locking seat 2 is installed at the bottom of the fixed mold, a positioning ball 231 is provided on the outer side of the elastic plate group 23. The positioning ball 231 is evenly distributed around the circumference of the elastic plate group 23. The positioning ball 231 forms a point contact elastic support with the inner wall of the mounting hole at the bottom of the fixed mold, thereby effectively absorbing axial impact and minor deformation during the installation process while ensuring radial preload. At the same time, to enable the lower locking seat 2 to be installed into the mounting hole at the bottom of the fixed mold more quickly, a locking wedge 232 is provided at the top of the elastic plate group 23. The locking wedge 232 is wedge-shaped with a rounded transition. The locking wedge 232 can effectively guide the base 21 to slide smoothly into the mounting hole along the axis of the mounting hole, avoiding jamming or damage caused by installation misalignment, and significantly improving assembly efficiency and repeatability accuracy.

[0033] like Figures 2-3 As shown, based on the structure of the lower locking seat 2, in order to enable the upper locking mechanism 1 and the lower locking seat 2 to form a locking engagement, a rectangular through hole 241 is provided in the locking block 24, and a locking hole 242 is provided on the inner wall of the top layer of the locking block 24. The directions of the rectangular through hole 241 and the locking hole 242 are perpendicular to each other, and the rectangular through hole 241 passes through the locking block 24 axially. The locking hole 242 does not pass through the locking block 24.

[0034] The rectangular through hole 241 is used to accommodate the corresponding locking structure in the upper locking mechanism 1, so that it can achieve axial guidance and radial limitation during the insertion process; the locking hole 242 is used to engage and lock with the locking structure corresponding to the upper locking mechanism 1.

[0035] like Figures 4-5As shown, the upper locking mechanism 1 includes an adjustment knob 11, a switching mechanism 18 is installed below the adjustment knob 11, a shaft tube 16 is installed on the outside of the switching mechanism 18, an inner shaft 19 is installed below the switching mechanism 18, a connecting shaft 194 is slidably installed inside the inner shaft 19, an inner sleeve 162 is slidably installed on the outside of the inner shaft 19, the inner sleeve 162 is slidably connected to the inner surface of the shaft tube 16, and a hook 14 is provided at the bottom end of the connecting shaft 194;

[0036] The hook 14 engages with the locking hole 242 of the lower locking seat 2. Simultaneously, the hook 14 can slide axially into the rectangular through hole 241, which serves as a positioning feature, ensuring precise alignment of the hook 14 along its axis during insertion. After alignment, the switching mechanism 18 can be driven by pressing the adjustment knob 11, causing the inner shaft 19 to drive the connecting shaft 194 axially downwards. Simultaneously, the switching mechanism 18 allows the hook 14 to rotate axially by ninety degrees, changing its horizontal position and thus reliably engaging with the locking hole 242, achieving rigid locking between the moving and fixed molds. In this mechanism, the connecting shaft 194 and the inner shaft 19 can slide together, allowing the hook 14 to extend and retract, providing a certain buffering effect. Its specific working principle is as follows:

[0037] A second limiting ring 192 is provided on the connecting shaft 194, a first limiting ring 191 is provided on the inner side of the upper surface of the inner sleeve 162, a third spring 193 is installed below the second limiting ring 192, the third spring 193 is sleeved on the outer periphery of the connecting shaft 194, and the bottom end of the third spring 193 abuts against the inner wall of the bottom end of the inner sleeve 162.

[0038] like Figure 3 As shown, a first spring 25 is provided above the base 21, and a telescopic shaft (not shown in the figure) is also installed above the base 21. The first spring 25 is sleeved on the outer periphery of the telescopic shaft, and a push plate 26 is installed on the first spring 25.

[0039] The elastic force of the third spring 193 is greater than that of the first spring 25;

[0040] After the hook 14 enters the rectangular through hole 241 and completes axial alignment, it enters the locking block 24. At the same time, the hook 14 abuts against the upper surface of the push plate 26. Because the elastic force of the third spring 193 is greater than that of the first spring 25, the hook 14 will continue to press down on the push plate 26, compressing the first spring 25, causing the push plate 26 to move downward along the telescopic axis. Then, the switching mechanism 18 switches and drives the connecting shaft 194 to rotate 90 degrees, causing the hook 14 to rotate 90 degrees horizontally. Then, the adjustment knob 11 is released, and the third spring 193 and the first spring 25 spring back to their original positions. At this time, the hook 14 is firmly embedded in the locking hole 242 under the action of the elastic restoring force, completing the precise alignment and rigid locking of the moving mold and the fixed mold.

[0041] The base 21 is provided with a locking nut (not shown in the figure) at the bottom. After the moving mold and the fixed mold are accurately aligned and rigidly locked, the telescopic shaft in the base 21 can be locked and fixed by the locking nut, thereby completely eliminating the axial movement of the telescopic shaft in the locked state, ensuring the connection between the locking block 24 and the moving mold is rigid and stable, and further improving the repeatability and structural durability of the multi-cavity mold frame under high frequency mold opening and closing conditions.

[0042] The movement relationship of the connecting shaft 194 within the inner sleeve 162 is as follows: the first limiting ring 191 and the second limiting ring 192 limit the maximum travel range of the connecting shaft 194 in the axial direction of the inner sleeve 162, that is, the maximum extension range that the hook 14 can achieve. The third spring 193 can provide a certain preload and buffering effect to prevent the hook 14 from coming out of the through hole 241 due to inertial impact during high-speed movement.

[0043] In this upper locking mechanism 1, the main function of the switching mechanism 18 is to drive the connecting shaft 194 to complete a precise 90-degree rotation after the hook 14 completes axial alignment and presses down on the push plate 26, so that the hook 14 engages in the locking hole 242. Its specific working principle is as follows: Figure 6 As shown;

[0044] The switching mechanism 18 includes a movable block 181, which is fixedly connected to the adjusting knob 11. Four sets of switching plates 182 are circumferentially mounted on the lower end of the movable block 181. The switching plates 182 are slidably connected to the inner wall of the shaft tube 16. Four sets of fixed limiting plates 187 are arranged below the switching plates 182. The fixed limiting plates 187 are fixedly connected to the inner shaft 19. The four sets of fixed limiting plates 187 are evenly distributed on the outer periphery of the inner shaft 19. The fixed limiting plates 187 are fixed to the inner wall of the shaft tube 16. The shaft tube 16 is slidably connected. The inner wall of the shaft tube 16 is provided with four sets of limiting protrusions 188. An upper limit groove 183 is provided between two sets of the switching plate 182. A lower limit groove 184 is provided between two sets of the fixed limiting plate 187. The upper limit groove 183 is slidably connected to the limiting protrusions 188. The lower limit groove 184 is slidably connected to the limiting protrusions 188. A second conversion tooth 185 is provided at the lower end of the switching plate 182. Two sets of first conversion teeth 186 are provided at the upper end of the fixed limiting plate 187.

[0045] As shown in the figure Figures 5-6 As shown, the mechanism exists in an initial state. In the initial state, the third spring 193 is in an extended state, the bottom end of the hook 14 abuts against the top end of the push plate 26, the first spring 25 is in a fully compressed state, and at the same time, the bottom end of the lower limit groove 184 is in contact with the lower end face of the limit protrusion 188, the upper limit groove 183 is always slidably connected with the limit protrusion 188, and at the same time, the second conversion tooth 185UI and the first conversion tooth 186 are not in contact.

[0046] When the movable block 181 is pressed down, the switching plate 182 moves down synchronously with the movable block 181. The upper limit groove 183 formed between the two sets of switching plates 182 slides on the limiting protrusion 188 and gradually approaches the fixed limiting plate 187. Each set of fixed limiting plates 187 is provided with two sets of first conversion teeth 186. The inclined surface on the second conversion tooth 185 contacts the inclined surface of one set of first conversion teeth 186 and generates radial thrust. At this time, the lower limit groove 184 formed between the two sets of fixed limiting plates 187 is still slidably connected with the limiting protrusion 188. The switching plate 182 pushes the fixed limiting plate 187 to slide along the inner shaft 19 and the limiting protrusion 188 until the fixed end of the lower limit groove 184 disengages from the limiting protrusion 188. At the same time, the fixed limiting plate 187 is pressed down. When the inner shaft 19 is pressed down, the connecting shaft 194 moves down synchronously and compresses the third spring 193. When the fixed end slot of the lower limit groove 184 disengages from the limit protrusion 188, the first conversion tooth 186 slides along the inclined surface of the second conversion tooth 185, causing the fixed limit piece 187 to rotate 45 degrees in the circumferential direction. After the movable block 181 is pressed down, the third spring 193 rebounds and resets, pushing the inner shaft 19 and the fixed limit piece 187 to move up. At this time, the straight inclined surface of the other tooth of the lower limit groove 184 re-engages with the limit protrusion 188, realizing circumferential positioning and locking. Pressing the movable block 181 again can repeat the 45-degree step rotation action in the circumferential direction, so that the hook 14 rotates 90 degrees and is completely aligned with the rectangular through hole 241, completing the precise guiding assembly of the moving mold and the fixed mold.

[0047] In the assembly of mold parts, different types of mold frames may need to install different mold components on the mold base. Therefore, the height of different types of mold frames is different. In order to solve the above problems, the upper locking mechanism 1 needs to have a certain degree of adjustability.

[0048] like Figure 7 and Figure 4 As shown, the outer periphery of the shaft tube 16 is provided with a spiral groove 163 and a straight groove 166. A fixing ring 13 is provided on the outer side of the shaft tube 16, and an actuating block 132 is provided on the inner wall of the fixing ring 13. The straight groove 166 passes through the spiral groove 163. A locking step 164 is provided at the intersection of the straight groove 166 and the spiral groove 163. An adjusting step 161 is provided inside the spiral groove 163. A ramp (not shown in the figure) is provided on the side of the locking step 164.

[0049] The retaining ring 13 is an embedded component, which is assembled together with the upper locking mechanism 1 into the hole in the mold frame, and is engaged with the through hole through the limiting straight groove 166 to ensure axial fixation;

[0050] The structure exists in an initial state. In this initial state, the actuating block 132 is located at the bottom end of the straight groove 166. With the latch 14 locked, the limiting protrusion 188 on the shaft tube 16 is locked to the upper limiting groove 183 and the lower limiting groove 184. That is, the movable block 181, the switching piece 182, the fixed limiting piece 187, the inner shaft 19, and the shaft tube 16 are all in an axially locked state. At this time, the movable block 181 reaches the top of the straight groove 166, and rotating the movable block 181 causes it to slide along the straight groove 166 into the spiral groove 163. A locking step 164 is provided at the intersection of each section of the straight groove 166 and the spiral groove 163 so that in the spiral state, the actuating block 132 can only... The shaft tube 16 is unidirectionally slid along the spiral groove 163 and gradually engages with the adjusting step 161 to adjust the axial extension length of the shaft tube 16, thereby adapting to multi-cavity mold frames of different heights. When the actuating block 132 slides into the end of the spiral groove 163, the shaft tube 16 reaches its maximum extension length, and the actuating block 132 enters its initial state. When the actuating block 132 is in the straight groove 166, the actuating block 132 can slide along the slope of the locking step 164 in the straight groove 166 and pass over the locking step 164. The slope is unidirectionally guided, so that the actuating block 132 can only slide upward along the straight groove 166 and cannot slide downward, or enter the spiral groove 163 in the upward movement.

[0051] In order to fix the length after adjustment, a limit ring 131 is installed on the fixing ring 13, a second spring 17 is installed on the limit ring 131, and a positioning sleeve 12 is installed on the second spring 17.

[0052] In practical applications, after assembly, the positioning sleeve 12 is fixed to the top of its mold frame, and the fixing ring 13 remains stationary. During the adjustment of the actuating block 132, the second spring 17 is compressed and stores energy. When the actuating block 132 reaches any adjustment step 161, the second spring 17 releases its elastic potential energy, allowing the actuating block 132 to precisely engage with the corresponding step, achieving instantaneous locking of the axial position. The coordinated design of the ramp and the locking step 164 ensures the unidirectionality and irreversibility of the adjustment process.

[0053] A planar bearing 22 is provided at the connection between the base 21 and the elastic plate group 23. The function of the planar bearing 22 is that when the movable block 181, the switching plate 182, the fixed limiting plate 187, the inner shaft 19 and the shaft tube 16 are in an axially locked state, the hook 14 will rotate when the length of the shaft tube 16 is adjusted. Therefore, the planar bearing 22 is provided to eliminate the axial frictional resistance of the hook 14 when it is in contact with the locking block 24 and the base 21 is fixed, so as to ensure that the hook 14 rotates smoothly and locks accurately.

[0054] In summary, this mechanism, with its dual protection of mechanical self-locking and elastic reset, is used for the rapid and precise positioning and locking of the moving and fixed molds of a multi-cavity mold frame. First, the lower locking seat 2 with elastic plate group 23 is pressed into the fixed mold mounting hole. Automatic centering and elastic fixation are achieved by the outer positioning ball 231. When the moving mold is aligned and placed, the hook 14 of the upper locking mechanism 1 slides into the rectangular through hole 241 inside the lower seat, pressing down the internal push plate 26 for axial pre-centering. At this time, pressing the upper adjustment knob 11 drives the switching mechanism 18, causing the connecting shaft 194 to precisely rotate the hook 14 by ninety degrees. After release, under the action of the internal spring reset force, the rotated hook 14 is pushed upward into the lateral locking hole 242, achieving rigid locking. Finally, it can be further locked by the bottom locking nut to prevent movement.

[0055] By adjusting the spiral groove 163 on the outer periphery of the shaft tube 16 in conjunction with the actuating block 132, the extension length of the upper locking mechanism 1 can be adjusted as a whole to adapt to mold frames of different heights, thereby achieving the effect of rapid alignment and guided assembly on different types of multi-cavity mold frames.
