DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] See also Figures 1 to 4, which is the first embodiment of the utility model, and the embodiment provides a technical solution: an injection mold, comprising a base 1, a support seat 2, a movable mold top seat 3, an upper movable mold 4 and a lower mold plate 5, two supports 2 are fixed on the top of the base 1, the lower mold plate 5 is installed on the top of the two supports 2, the upper movable mold 4 is fixed on the bottom surface of the movable mold top seat 3, a gate 7 is arranged on the top of the movable mold top seat 3, the upper movable mold 4 is fitted with the top surface of the lower mold plate 5, a plurality of molding cavities are provided on the top surface of the lower mold plate 5, two easy-to-disassemble mechanisms 6 are arranged between the lower mold plate 5 and the support seat 2, the easy-to-disassemble mechanism 6 comprises an insert block 63 welded and fixed to the top surface of the support seat 2, a slot 64 for inserting the insert block 63 is provided on the bottom surface of the lower mold plate 5, and the insert block 63 is inserted into the bottom surface of the lower mold plate 5. The block 63 is inserted into the slot 64. The easy disassembly and assembly mechanism 6 also includes a side end block 61 and a limiting cross bar 65. The limiting cross bar 65 is welded and fixed to the side of the side end block 61. The surface of the plug block 63 is penetrated with a limiting cross hole 66 corresponding to the limiting cross bar 65. The side of the lower template 5 is penetrated with a through hole corresponding to the limiting cross bar 65. The side end block 61 is attached to the side of the lower template 5, and the end of the limiting cross bar 65 passes through the through hole to the limiting cross hole 66, which can effectively limit the lower template 5 and realize the installation of the lower template 5. The easy disassembly and assembly mechanism 6 also includes a side dial plate 62, an inner groove 68 and an inner slider 69. The inner groove 68 is opened inside the support seat 2, and the inner slider 69 and a spring 610 are arranged in the inner groove 68. The top surface of the inner slider 69 is welded and fixed with a limit clamping rod 611, and the surface of the limit cross bar 65 is penetrated with a limit clamping hole 612 corresponding to the limit clamping rod 611. The top of the limit clamping rod 611 penetrates into the limit clamping hole 612, which can stably limit the limit cross bar 65 to ensure the installation stability of the lower template 5. The easy-to-disassemble mechanism 6 also includes a side groove 614 opened on the side of the support seat 2, and a bottom connecting rod 613 is fixed to the bottom surface of the inner slider 69. The bottom end of the bottom connecting rod 613 penetrates into the side groove 614, and a side slider 615 fixedly connected to the bottom connecting rod 613 is arranged in the side groove 614. The side dial plate 62 is arranged on the side of the support seat 2 and covers the side groove 614. One end of the side slider 615 is connected to the side The shift plate 62 is fixedly connected. If the lower template 5 needs to be removed for replacement later, it is only necessary to pull down the side shift plate 62 first, so that the side slide block 615 pulls down the inner slide block 69 through the bottom connecting rod 613, and compresses the spring 610 until the top of the limiting clamping rod 611 moves out of the limiting clamping hole 612. At this time, the limit on the limiting cross bar 65 can be released, and then the side end block 61 is pulled sideways, and the limiting cross bar 65 is pulled out of the limiting cross hole 66, so as to release the limit on the lower template 5. The operator lifts the lower template 5 and can quickly remove the lower template 5 for replacement, which greatly improves the convenience of disassembly and replacement of the lower template 5. Compared with the original technology using bolts and other installation methods, it can save disassembly and assembly time and improve the convenience of disassembly and assembly.

[0020] A rod hole is formed between the inner groove 68 and the side groove 614 , and the rod hole corresponds to the bottom connecting rod 613 , so that the bottom connecting rod 613 can pass through smoothly.

[0021] A vertical hole is defined between the inner groove 68 and the limiting transverse hole 66 , and the vertical hole corresponds to the limiting clamping rod 611 , so that the limiting clamping rod 611 can pass through smoothly.

[0022] The top end of the spring 610 is in tight contact with the bottom surface of the inner sliding block 69 , and the bottom end of the spring 610 is in tight contact with the bottom inner wall of the inner groove 68 .

[0023] Example 2

[0024] See also Figures 1 to 5 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that, by means of the auxiliary structure, when the limiting cross bar 65 has not yet been inserted into the limiting cross hole 66, the positioning protrusion 616 can play a certain auxiliary limiting role on the lower template 5.

[0025] Specifically, the easy-to-disassemble mechanism 6 also includes an auxiliary structure, which includes a rubber inner pad 67 embedded in the inner wall of one side of the slot 64. A positioning protrusion 616 is provided on the surface of the rubber inner pad 67, and the positioning protrusion 616 is embedded in the limiting transverse hole 66. When the plug block 63 is inserted into the slot 64, the positioning protrusion 616 will be squeezed to undergo elastic deformation and be squeezed into the limiting transverse hole 66. At this time, when the limiting cross bar 65 has not yet been inserted into the limiting transverse hole 66, the positioning protrusion 616 can play a certain auxiliary limiting role on the lower template 5, which is convenient for subsequent limiting steps. The positioning protrusion 616 and the rubber inner pad 67 are an integrated structure, both of which are made of fluororubber. When squeezed, they will undergo elastic deformation. A deformation cavity corresponding to the positioning protrusion 616 is opened inside the rubber inner pad 67, so that the positioning protrusion 616 has sufficient deformation space when squeezed.

[0026] Among them, an installation groove matched with the rubber inner pad 67 is opened on the inner wall of one side of the slot 64, and the rubber inner pad 67 is glued and fixed in the installation groove for embedded installation of the rubber inner pad 67.

[0027] The structural principles of the injection mold itself in the utility model are all technologies that have been disclosed in the prior art. For details, please refer to the existing patent with publication number CN209079080U, which will not be described in detail here.

[0028] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), 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.
