Description

Technical Field

[0001] This utility model belongs to the field of injection mold technology, and in particular relates to a locking module with a safety buckle for injection molds. Background Technology

[0002] In injection molds, locking devices (locking modules) are frequently used to securely connect the stationary and moving molds, preventing loosening or displacement during injection molding and ensuring product quality and mold safety. Traditional locking methods typically employ bolts, set screws, or threaded locking blocks. These methods have the following significant drawbacks:

[0003] 1. Cumbersome operation and low efficiency: Each assembly and disassembly requires the use of special tools such as wrenches and Allen wrenches to tighten and loosen, which is time-consuming and labor-intensive, especially in situations where frequent replacement of inserts or maintenance is required.

[0004] 2. Inconvenient control of locking force: Too tight may cause deformation of parts or damage to threads, while too loose will not lock effectively.

[0005] 3. Prone to wear: The threads are prone to wear under repeated tightening, which leads to a decrease in locking force or failure.

[0006] Therefore, there is an urgent need to develop a mold locking device that is easy and quick to operate, requires no tools, has reliable locking, and is highly safe. Utility Model Content

[0007] The purpose of this invention is to provide a locking module with a safety buckle for injection molds, thereby solving existing problems.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model relates to a locking module with a safety buckle for injection molding, comprising a locking module assembly. The locking module assembly consists of two locking pins, a locking module, and two locking buckles. The upper surface of the locking module has symmetrical locking holes on both sides that match the locking pins. The locking buckles include locking pins, one end of which is fixed to a fixing block. A safety buckle is rotatably connected to the fixing block. The front peripheral side of the locking pin has a pin hole that matches the locking pin, and the tail end of the locking pin has a threaded post.

[0010] In one embodiment, the locking module assembly is disposed on the injection mold, which consists of a moving mold and a fixed mold; an ejector plate is fixedly installed at the lower end of the moving mold, and an injection runner plate is fixedly installed at the upper end of the fixed mold; both the lower end of the ejector plate and the upper end of the injection runner plate are equipped with mounting plates.

[0011] In one embodiment, the moving mold and the fixed mold have mounting holes on their opposite surfaces that match the locking pins. The mounting holes of the moving mold and the fixed mold are positioned to match each other. The mounting holes include threaded holes and smooth holes.

[0012] In one embodiment, the shape and size of the threaded post are adapted to the threaded hole of the mounting hole, the shape and guide of the locking post are adapted to the smooth hole of the mounting hole, and the threaded post is threadedly connected to the mounting hole.

[0013] In one embodiment, the shape and size of the locking pin are adapted to the pin hole, and the locking pin is inserted into the pin hole.

[0014] In one embodiment, the shape and size of the locking hole are adapted to the locking post, the locking hole and the locking post are inserted together, the shape and size of the safety buckle are adapted to the locking post, and the safety buckle and the locking post cooperate with each other.

[0015] This utility model has the following beneficial effects:

[0016] 1. Simple and quick operation, no tools required: The locking pin and pin hole are engaged, and the safety buckle is rotated to lock and unlock the mold quickly. Compared with the traditional threaded locking method, it eliminates the need for wrenches or Allen wrenches, significantly improving assembly and disassembly efficiency. It is especially suitable for occasions where inserts need to be frequently replaced or molds need to be maintained.

[0017] 2. Reliable locking and high security:

[0018] Double locking: The locking pin inserts into the pin hole to provide the main locking force, while the rotating safety buckle acts as a second safety measure, effectively engaging with the locking pin to prevent it from accidentally coming out under the vibration of the injection molding machine or accidental impact, greatly enhancing the reliability of locking and the safety of mold operation.

[0019] Stable interlocking: The precise interlocking of the locking hole and the locking pin, and the matching interlocking of the locking pin and the pin hole, ensure stable and reliable transmission of locking force, avoiding the problems of over-tightening (component deformation, thread damage) or over-loosening (locking failure) caused by human factors in traditional threaded locking.

[0020] 3. Low wear and tear, long service life:

[0021] Core locking without thread wear: The locking action of the core (pin and engagement) does not involve repeated turning of the threads, eliminating the thread wear problem caused by frequent operation of traditional threaded locking blocks, and avoiding the resulting decrease in locking force or failure.

[0022] The thread is only used for installation and fixing: The threaded post is only used to initially fix the locking post in the mounting hole of the mold. After installation, it basically does not bear repeated operating stress, and its thread wear risk is extremely low.

[0023] 4. Modular structure, easy maintenance: The locking module assembly consists of standardized locking pillars, locking modules, and locking buckles, with a clear structure. If individual components are damaged, they can be easily replaced individually, reducing maintenance costs and downtime.

[0024] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0039] Furthermore, the locking module assembly 8 is disposed on the injection mold, which consists of a moving mold 2 and a fixed mold 1; an ejector plate 3 is fixedly installed at the lower end of the moving mold 2, and an injection runner plate 4 is fixedly installed at the upper end of the fixed mold 1. Mounting plates 5 are installed at the lower end of the ejector plate 3 and the upper end of the injection runner plate 4.

[0040] Furthermore, mounting holes 7 matching the locking pins 9 are provided on the opposite surfaces of the moving mold 2 and the fixed mold 1. The mounting holes 7 on the moving mold 2 and the fixed mold 1 are positioned to match the mounting holes 7 on the fixed mold 1. The mounting holes 7 include threaded holes and smooth holes.

[0041] Furthermore, the shape and size of the threaded post 901 are adapted to the threaded hole of the mounting hole 7, and the shape and guide of the locking post 9 are adapted to the smooth hole of the mounting hole 7. The threaded post 901 and the mounting hole 7 are threadedly connected.

[0042] Furthermore, the shape and size of the locking pin 1101 are adapted to the pin hole 902, and the locking pin 1101 is inserted into the pin hole 902.

[0043] Furthermore, the shape and size of the locking hole 1001 are adapted to the locking post 9, and the locking hole 1001 and the locking post 9 are inserted together.

[0044] Example 2

[0045] This utility model discloses a method for using a locking module with a safety buckle for injection molding, comprising the following steps:

[0046] Step 1: Install the clamping columns:

[0047] Screw the threaded post 901 at the tail end of the mold locking post 9 into the threaded hole of the corresponding mounting hole 7 of the moving mold 2 or the fixed mold 1 to ensure that the smooth post part at the front end of the mold locking post 9 fits tightly with the smooth hole of the mounting hole 7, thus completing the fixed installation of the mold locking post 9 on the mold.

[0048] Step 2: Mold Closure and Positioning

[0049] Close the moving mold 2 and the fixed mold 1, so that the front ends of the two locking pins 9 fixed on the moving mold 2 and the fixed mold 1 are aligned with the locking holes 1001 on both sides of the locking module 10.

[0050] Step 3: Insert the lock module:

[0051] Press down the locking module 10 so that the locking holes 1001 on both sides are fully inserted into the front end of the corresponding locking post 9 until the locking module 10 fits against the mold surface.

[0052] Step 4: Insert the locking pin:

[0053] Holding the mold locking buckle 11, insert the mold locking pin 1101 horizontally into the corresponding pin hole 902 on the front peripheral side of the mold locking column 9 until the mold locking pin 1101 is fully inserted into place, thus achieving initial locking.

[0054] Step 5: Lock the safety buckle:

[0055] Rotate the safety buckle 1103 on the mold locking buckle 11 so that it rotates around the fixing block 1102 and engages with the outer surface of the mold locking post 9. When you hear a "click" or feel a clear sense of engagement, the double locking is complete. At this time, the safety buckle 1103 physically prevents the mold locking pin 1101 from disengaging.

[0056] Step Six: Unlocking Operation

[0057] When mold opening is required, first turn the safety buckle 1103 to rotate it away from the surface of the mold locking post 9 (return to the "unlocked" position), then pull out the mold locking pin 1101 horizontally, and finally lift the locking module 10 upwards to disengage the mold locking hole 1001 from the mold locking post 9, thus separating the mold.
