[0002] The front mold plate, also known as the fixed mold, is a fixed part that includes the main structure of the mold, the front mold plate, and the cavity. The mold frame is the supporting part of the mold, used to assemble and fix the various parts of the mold, ensuring that the mold can be installed on the die-casting machine for operation.

[0003] The patent application CN212860256U discloses a front mold positioning device for injection molds, comprising a fixed mold plate and a movable mold plate. A connecting plate is fixedly connected to the side of the movable mold plate away from the fixed mold plate. A fixing plate is fixedly connected to the side of the connecting plate away from the movable mold plate. A guide plate is provided on the side of the fixing plate away from the connecting plate. A first locking base is bolted to the side of the fixed mold plate away from the movable mold plate. A first locking cylinder is fixedly connected to one side of the first locking base. The advantages of this invention are: the cooperation of the electromagnet and the first guide rod prevents the reduction in mold quality caused by movement; the cooperation of the first locking cylinder, support rod, first locking plate, and second locking plate improves the firmness between the fixed mold plate and the movable mold plate; and the threaded connection of a fixing knob on the side of the second guide rod near the fixing plate allows for a tight connection between the guide plate and the fixing plate, facilitating replacement.

[0004] However, the above-mentioned device still has the following problems during implementation:

[0005] When installing the existing front template and mold frame, bolts are generally used for fixing. After long-term use, the external threads on the bolt surface are prone to wear, making it difficult to disassemble and replace later, thus reducing the practicality of the mold frame. Utility Model Content

[0006] The purpose of this utility model is to provide a mold front template frame to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A mold front template frame includes a mold frame, a front template, and a cavity. The cavity is opened at the top of the front template, and the front template is located at the top of the mold frame. Both sides of the front template are fixedly connected to mating blocks. The bottom of the mating blocks is provided with mating grooves. A shell is provided inside the mating grooves. The bottom of the shell is fixedly connected to the top of the mold frame. A positioning mechanism is provided inside the shell. Several stabilizing mechanisms are provided on both sides of the front template.

[0009] The positioning mechanism includes a linkage block disposed inside the housing, and positioning blocks are disposed on both sides of the linkage block. The positioning blocks are connected to the linkage block by a connecting rod. Two positioning rods are fixedly connected to one side of the positioning block. One end of the positioning rod extends through to the outside of the housing. Positioning holes for use with the positioning rods are provided on both sides of the mating block.

[0010] Preferably, the stabilizing mechanism includes stabilizing blocks fixedly connected to both sides of the front template. The top of the stabilizing block is provided with a stabilizing hole, and a stabilizing column is inserted into the inner wall of the stabilizing hole. The bottom of the stabilizing column is fixedly connected to the top of the mold frame, and a fastening ring is fixedly connected to the inner wall of the stabilizing hole.

[0011] Preferably, the top and bottom of the positioning block are fixedly connected to sliding blocks, and the inner wall of the housing is provided with sliding grooves that cooperate with the sliding blocks.

[0012] Preferably, a tension spring is fixedly connected to one side of the linkage block, and one end of the tension spring is fixedly connected to the inner wall of the housing.

[0013] Preferably, a traction rod is fixedly connected to the side of the linkage block away from the tension spring, and one end of the traction rod extends through to the outside of the housing and is fixedly connected to a pull ring.

[0014] Preferably, the fastening ring is made of rubber, and its inner wall is in contact with the surface of the stabilizing column.

[0015] Preferably, the top of the stabilizing column is conical.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model, by setting a positioning mechanism, allows the pull ring to be pulled away from the housing. The pull ring moves the traction rod and the linkage block, and the linkage block moves the connecting rod around the hinge to make appropriate adjustments. At the same time, it pulls the two positioning blocks along the trajectory of the sliding block and the sliding groove to move closer to each other. The positioning blocks will drive the positioning rod to leave the positioning hole. Then, the front template can be removed by moving it upward. During installation, by aligning the docking groove with the housing, the front template is pushed downward so that the housing enters the docking block. Then, the pull ring is released, and the tension generated by the tension spring drives the linkage block to reset. The steps are reversed. Finally, the two positioning blocks will move away from each other, so that the positioning rod enters the corresponding positioning hole. This completes the fixing of the front template and the mold frame, thereby facilitating disassembly and replacement.

[0018] 2. By setting a stabilizing mechanism, this utility model can ensure that after the docking groove is aligned with the shell, while the front template is pressed down, the tapered part at the top of the stabilizing column will first enter the fastening ring and open it. Then the stabilizing column will completely enter the fastening ring, thereby effectively improving the stability of the connection between the front template and the mold frame.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Please see Figures 1-5 This utility model provides a technical solution:

[0027] Example 1:

[0028] A mold front template frame includes a mold frame 1, a front template 2, and a cavity 3. The cavity 3 is opened on the top of the front template 2. The front template 2 is located on the top of the mold frame 1. Both sides of the front template 2 are fixedly connected to a mating block 4. The bottom of the mating block 4 is provided with a mating groove 5. A shell 6 is provided inside the mating groove 5. The bottom of the shell 6 is fixedly connected to the top of the mold frame 1. A positioning mechanism is provided inside the shell 6. Several stabilizing mechanisms are provided on both sides of the front template 2.

[0029] The positioning mechanism includes a linkage block 7 disposed inside the housing 6. Positioning blocks 8 are provided on both sides of the linkage block 7. The positioning blocks 8 are connected to the linkage block 7 by a connecting rod 9. Two positioning rods 10 are fixedly connected to one side of the positioning block 8. One end of the positioning rod 10 extends through to the outside of the housing 6. Positioning holes 11 that cooperate with the positioning rods 10 are provided on both sides of the mating block 4.

[0030] In this embodiment, considering that the existing front template 2 and mold frame 1 are generally fixed with bolts, the external threads on the bolts are prone to wear after long-term use, making it difficult to disassemble and replace them later, a positioning mechanism is set up. By pulling the pull ring 20 away from the housing 6, the pull ring 20 drives the traction rod 19 and the linkage block 7 to move. The linkage block 7 drives the connecting rod 9 to rotate appropriately around the hinge. At the same time, the two positioning blocks 8 are pulled to move towards each other along the trajectory of the sliding block 16 and the sliding groove 17. The positioning blocks 8 will drive the positioning rod 10 to leave the positioning hole 11. Then, the front template 2 can be removed by moving it upward. During installation, by aligning the docking groove 5 with the position of the housing 6, the front template 2 is pushed downward so that the housing 6 enters the docking block 4. Then, the pull ring 20 is released. The tension generated by the tension spring 18 drives the linkage block 7 to reset. The opposite of the above steps, the two positioning blocks 8 will eventually move towards each other, so that the positioning rod 10 enters the corresponding positioning hole 11. This completes the fixing of the front template 2 and the mold frame 1, thereby achieving the function of easy disassembly and replacement.

[0031] This solves the problem that when the existing front template 2 and the mold frame 1 are installed, bolts are generally used to fix them. However, the external threads on the surface of the bolts are easily worn after long-term use, making it difficult to disassemble and replace them later.

[0032] The top and bottom of the positioning block 8 are fixedly connected to the sliding block 16, and the inner wall of the housing 6 is provided with a sliding groove 17 that cooperates with the sliding block 16.

[0033] In this embodiment, by setting the sliding block 16 and the sliding groove 17, when the connecting rod 9 drives the positioning block 8 and other structures to move, the positioning block 8 and other structures can only move along the trajectory of the sliding block 16 and the sliding groove 17, thereby improving the stability of their movement.

[0034] A tension spring 18 is fixedly connected to one side of the linkage block 7, and one end of the tension spring 18 is fixedly connected to the inner wall of the housing 6.

[0035] In this embodiment, by setting a tension spring 18, when the pull ring 20 is released, the tension generated by the tension spring 18 can drive the positioning block 8 and the positioning rod 10 to move, so that the positioning rod 10 enters the positioning hole 11 and plays a role in resetting.

[0036] A traction rod 19 is fixedly connected to the side of the linkage block 7 away from the tension spring 18. One end of the traction rod 19 extends through to the outside of the housing 6 and is fixedly connected to a pull ring 20.

[0037] In this embodiment, by setting the traction rod 19 and the pull ring 20, the user can easily control the positioning block 8 and the positioning rod 10 to move, which facilitates driving.

[0038] Example 2:

[0039] Based on Embodiment 1, the positioning mechanism in this embodiment facilitates the disassembly and replacement of the front template 2 and the mold frame 1. However, considering that the positioning mechanism is fixed on both sides, it is difficult to guarantee the stability after installation. In this application, the stabilizing mechanism includes stabilizing blocks 12 fixedly connected to both sides of the front template 2. The top of the stabilizing block 12 is provided with a stabilizing hole 13. A stabilizing column 14 is inserted into the inner wall of the stabilizing hole 13. The bottom of the stabilizing column 14 is fixedly connected to the top of the mold frame 1. A fastening ring 15 is fixedly connected to the inner wall of the stabilizing hole 13.

[0040] In this embodiment, considering that the positioning mechanism is fixed on both sides, it is difficult to guarantee the stability after installation. Therefore, by setting a stabilizing mechanism, after the docking groove 5 is aligned with the housing 6, while the front template 2 is pressed down, the tapered part at the top of the stabilizing column 14 will first enter the fastening ring 15, opening the fastening ring 15. Afterwards, the stabilizing column 14 will completely enter the fastening ring 15. Figure 1 , Figure 2 and Figure 3 As shown, this effectively improves the stability of the connection between the front template 2 and the mold frame 1;

[0041] This solves the problem that it is difficult to ensure the stability of the installation when the positioning mechanism is fixed on both sides.

[0042] The fastening ring 15 is made of rubber, and its inner wall is in contact with the surface of the stabilizing post 14.

[0043] In this embodiment, by making the material of the fastening ring 15 as rubber, when the stabilizing rod enters the inside of the fastening ring 15, it will expand the fastening ring 15 by one ring and fit tightly against the surface of the stabilizing column 14, thereby effectively improving the connection between the front template 2 and the mold frame 1.

[0044] The top of the stabilizing column 14 is conical.

[0045] In this embodiment, by setting the top of the stabilizing post 14 to be conical, it is easier for the stabilizing post 14 to enter the fastening ring 15 in the stabilizing hole, which facilitates docking.

[0046] Working principle: The user pulls the pull ring 20 to the side away from the housing 6. The pull ring 20 moves the traction rod 19 and the linkage block 7. The linkage block 7 moves the connecting rod 9 to rotate appropriately around the hinge. At the same time, it pulls the two positioning blocks 8 to move towards each other along the trajectory of the sliding block 16 and the sliding groove 17. The positioning blocks 8 will move the positioning rod 10 away from the positioning hole 11. Then, the front template 2 can be removed by moving it upward. During installation, the front template 2 is pushed downward by aligning the docking groove 5 with the housing 6, so that the housing 6 enters the docking block 4. Then, the pull ring 20 is released. The tension generated by the tension spring 18 drives the linkage block 7 to reset. The steps are reversed. Finally, the two positioning blocks 8 will move towards the side away from each other, so that the positioning rod 10 enters the corresponding positioning hole 11. This completes the fixing of the front template 2 and the mold frame 1, thus achieving the function of easy disassembly and replacement.

[0047] After the mating groove 5 is aligned with the housing 6, while the front template 2 is pressed down, the tapered part at the top of the stabilizing column 14 will first enter the fastening ring 15, opening the fastening ring 15. Then, the stabilizing column 14 will completely enter the fastening ring 15. Figure 1 , Figure 2 and Figure 3 As shown, this effectively improves the stability of the connection between the front template 2 and the mold frame 1.

[0048] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
