[0016] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0017] Example:

[0018] like Figures 1 to 5 As shown, this utility model provides an injection mold that facilitates core replacement, including a template 11, a body 12 mounted on the template 11, and an installation groove 13 on the body 12; two sets of electric locking discs 14 are provided in the installation groove 13, and the extension ends of the two sets of electric locking discs 14 clamp the core 15; a sensor 17 is installed at the bottom of the installation groove 13, and a protective cover 18 is provided on the sensor 17; an installation block 19 is provided at one end of the body 12, and a controller 21 is provided on the installation block 19; the controller 21 is electrically connected to the sensor 17 and the electric locking discs 14 respectively.

[0019] Specifically, template 11 is a high-strength cast iron rectangular plate with excellent load-bearing capacity and deformation resistance, and can be directly fixed to the workbench of the production line; the body 12 is an aluminum alloy block structure, which is vertically fixed to the upper surface of template 11 by bolts, and a rectangular mounting groove 13 adapted to the shape of mold core 15 is opened on its top to accommodate mold core 15. Two sets of electric locking discs 14 are electric locking structures, symmetrically embedded in the inner walls of both sides of the mounting groove 13, and anti-slip rubber pads are attached to the telescopic ends. They can lock both sides of mold core 15 through telescopic movement to prevent mold core 15 from shifting during the process; a sensor 17 is installed in the center of the bottom of the mounting groove 13 to detect whether mold core 15 is installed in place, and a transparent plastic protective cover 18 is covered on its outside to prevent plastic molten material from splashing and contaminating the sensor. Mounting block 19 is an L-shaped metal block welded to the outer wall of one side of the main body 12. The top is embedded with a controller 21. The controller 21 is connected to the sensor 17 and the electric locking disc 14 through wires. When the sensor 17 detects that the mold core 15 is in place, it automatically sends a signal to the electric locking disc 14 to trigger the locking action. At the same time, the working status is displayed on the screen.

[0020] It should be noted that the electric locking disc 14 can be an SMCML GPM20-10 model electric locking disc to quickly and stably lock the mold core 15, preventing the mold core 15 from shifting during operation; the sensor 17 can be an Omron E3Z-D61 model diffuse reflection photoelectric sensor to detect whether the mold core 15 is installed in place, and is adapted to protection requirements to resist molten material splashes and dust contamination.

[0021] The template 11 is provided with a positioning plate 22, the positioning plate 22 is provided with a screw 23, the screw 23 is fitted with a connecting plate 24, and the connecting plate 24 is connected to the body 12.

[0022] Specifically, the positioning plate 22 is a stainless steel circular plate, which is fixed to the upper surface of the template 11 near the body 12 by bolts, and a screw 23 is vertically installed at the center of the plate; the connecting plate 24 is a thin steel plate, with a threaded hole at one end that matches the screw 23, and is fitted onto the screw 23, and the other end is fixed to the side wall of the body 12 by welding. This ensures that the body 12 is fixed to the template 11.

[0023] One end of the mold core 15 is provided with a gasket 25, and the gasket 25 is provided with a positioning hole; the bottom of the mounting groove 13 is provided with multiple sets of fixing sleeves 27, and each fixing sleeve 27 is provided with a positioning pin 28, which cooperates with the positioning hole.

[0024] Specifically, the gasket 25 is a silicone buffer pad, which is attached to the end of the mold core 15 facing the bottom of the mounting groove 13 to prevent the mold core 15 from colliding hard with the bottom of the groove when it is lowered; the positioning holes are circular through holes, evenly spaced along the edge of the gasket 25, with a total of 4 sets; the fixing sleeve 27 is a cylindrical sleeve made of brass, welded to the bottom of the mounting groove 13 corresponding to the positioning hole position, and a positioning pin 28 is embedded inside it. When the mold core 15 is placed into the mounting groove 13, the positioning pin 28 is inserted into the positioning hole, forming a circumferential limit to prevent the mold core 15 from rotating before locking, further enhancing the positioning stability.

[0025] The main body 12 is provided with two sets of card seats 29, and the two sets of card seats 29 are provided with quick-release buckles 31. The quick-release buckles 31 are connected to the electric locking plate 14 through the screw 23.

[0026] Specifically, the mounting base 29 is made of metal and is symmetrically welded to the outer wall of the main body 12, corresponding to the position of the electric locking disc 14 in the mounting groove 13. The quick-release buckle 31 is a flexible metal clip, one end of which is fixed to the outer shell of the electric locking disc 14 by a screw 23, and the other end is engaged in the slot of the mounting base 29. When it is necessary to replace the electric locking disc 14, simply press the flexible end of the quick-release buckle 31 to release it from the mounting base 29, without having to remove multiple sets of bolts, greatly shortening maintenance and replacement time and improving production efficiency.

[0027] The main body 12 is provided with a mounting base 34, and a warning light 35 is installed on the mounting base 34. The warning light 35 is electrically connected to the controller 21.

[0028] Specifically, the mounting base 34 is a cylindrical metal bracket welded to the top edge of the main body 12; the warning light 35 is a tri-color LED light, fixed to the top of the mounting base 34 with bolts and connected to the controller 21 via wires. When the equipment is running normally, the warning light 35 illuminates green; when the mold core 15 is not in place, it illuminates yellow; when the electric locking disc 14 malfunctions or the sensor 17 is abnormal, it illuminates red and flashes, visually reminding the operator of the equipment status and preventing production accidents caused by misoperation.

[0029] It should be noted that the warning light 35 can use a Schneider XVB-C5B3 model tri-color LED warning light to provide a direct indication of the equipment status.

[0030] The mounting slot 13 is provided with a bushing 32, and a wear-resistant sleeve 33 is installed on the bushing 32.

[0031] Specifically, bushing 32 is a copper annular sleeve, which is inserted into the inner wall of the mounting groove 13 by interference fit, serving as a transition buffer; wear-resistant sleeve 33 is a polyurethane wear-resistant ring, which is fitted inside bushing 32 and has a smooth surface. During the installation and removal of mold core 15, it comes into direct contact with wear-resistant sleeve 33, which can reduce frictional wear between mold core 15 and the inner wall of mounting groove 13, while avoiding scratches caused by metal-to-metal collisions, thus extending the service life of mounting groove 13 and mold core 15.

[0032] One end of the template 11 is provided with a support block 36, and the bottom of the support block 36 is equipped with an anti-slip pad 37.

[0033] Specifically, the support block 36 is a cast iron block, welded to the end of the template 11 away from the main body 12, forming a balanced support with the main body 12 to prevent the template 11 from tilting due to unilateral force; the anti-slip pad 37 is a nitrile rubber pad with diamond-shaped anti-slip patterns pressed on the surface, and is fixed to the bottom of the support block 36 by adhesive. The anti-slip pad 37 can increase the friction with the table surface, prevent the equipment from shifting during production vibration, and improve overall stability.

[0034] The specific usage and function of this embodiment are as follows: Before use, fix the template 11 on the injection molding machine worktable. The cast iron support block 36 at one end of the template 11 forms a balanced support with the body 12. The anti-slip pad 37 at the bottom increases friction through a diamond pattern to prevent equipment displacement caused by production vibration. Rotate the positioning plate 22, and the connecting plate 24 driven by the screw 23 finely adjusts the position of the body 12 to ensure that the mounting groove 13 is aligned with the injection molding machine outlet, preparing for subsequent molding.

[0035] During mold installation, the end of the mold core 15 with the gasket 25 is placed downwards and aligned with the positioning pin 28 at the bottom of the mounting groove 13, so that the positioning hole and the positioning pin 28 cooperate to form a circumferential limit. During the lowering process, the silicone gasket 25 buffers the collision between the mold core 15 and the bottom of the groove to avoid damage. When the mold core 15 is fully inserted, the sensor 17 at the bottom of the mounting groove 13 detects the signal and transmits it to the controller 21 in real time. The controller 21 automatically triggers two sets of electric locking discs 14, and the anti-slip rubber pads at their telescopic ends clamp the two sides of the mold core 15 to complete the automatic locking. At this time, the warning light 35 lights up green, indicating that production can be started.

[0036] During injection molding production, the copper bushing 32 and polyurethane wear-resistant sleeve 33 on the inner wall of the mounting groove 13 reduce frictional wear when the mold core 15 is opened and closed, and extend the service life of the parts. If the mold core 15 is loose or the sensor 17 is abnormal, the controller 21 will immediately trigger the warning light 35 to flash red and stop the equipment to avoid the generation of defective parts.

[0037] When the mold core 15 needs to be replaced, an unlocking command is sent through the controller 21, and the electric locking plate 14 retracts to loosen the mold core 15. The old mold core 15 can be directly removed and the new mold core 15 can be installed without any tools. If the electric locking plate 14 malfunctions, the quick-release buckle 31 on the outer side of the main body 12 can be pressed to disassemble and maintain the mold core 15, which greatly shortens the mold replacement and maintenance time.

[0038] This mold solves the problems of cumbersome mold core replacement and inaccurate positioning in traditional molds by automatically positioning, locking, and warning linkage. It is suitable for small-batch, multi-variety injection molding production, improving production efficiency and product qualification rate. It is applicable to injection molding scenarios such as plastic parts and packaging containers.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
