DETAILED DESCRIPTION

[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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0026] like Figures 1 to 7 As shown, the present invention provides an injection mold capable of secondary injection molding, comprising a base 1, a lower mold 2 and a bracket 3 are fixedly installed on the top of the base 1, a connecting block 4 is fixedly installed on the top of the bracket 3, a cylinder 5 is fixedly installed on the top of the connecting block 4, an output shaft 6 is fixedly installed on the output end of the cylinder 5, an upper mold 7 is fixedly installed on the bottom of the output shaft 6, a telescopic shaft 8 is fixedly installed on the bottom of the upper mold 7, a spring 9 is sleeved on the outer side of the telescopic shaft 8, a pressing block 10 is fixedly installed on the bottom of the spring 9, a slide groove 14 is provided inside the lower mold 2, a slider 15 is slidably connected inside the slide groove 14, a connecting bin 16 is provided inside the slider 15, a sliding rod 17 is slidably connected inside the connecting bin 16, a spring 18 is sleeved on the outer side of the sliding rod 17, a connecting plate 19 is fixedly installed above the spring 18, an installation bin 20 is provided inside the connecting plate 19, and a limiting ring 21 is fixedly installed inside the installation bin 20.

[0027] The limiting ring 21 is located inside the connecting plate 19. Its main function is to place the material placement bin into the installation bin 20 when secondary injection molding is required. At this time, the installation bin 20 limits the material placement bin to prevent the material placement bin from continuing to move downward. At the same time, the material is located directly above the shaping component 13. When the cylinder 5 is started and the upper mold 7 is driven downward by the output shaft 6 for pressing, the material is kept in a fixed position, thereby achieving the effect of improving the accuracy of the secondary injection molding.

[0028] A slide groove 11 is provided inside the lower mold 2 , a slider 12 is slidably connected inside the slide groove 11 , and a shaping component 13 is fixedly installed on a side of the slider 12 away from the slide groove 11 .

[0029] The shaping component 13 is located inside the lower mold 2. Its main function is to facilitate shaping of the material during the first injection molding by installing the shaping component 13 inside, thereby achieving the effect of convenient injection molding. At the same time, since the shaping component 13 is installed through the sliding action of the slider 12 and the slide groove 11, the shaping component 13 can be easily disassembled and replaced.

[0030] Among them, a baffle 22 is fixedly installed at the bottom of the slider 2 15, a slide groove 3 23 is opened inside the lower mold 2, a slide plate 24 is slidably connected inside the slide groove 3 23, a connecting column 25 is fixedly installed above the slide plate 24, a top ball 26 is fixedly installed above the connecting column 25, and a control board 30 is fixedly installed above the connecting column 25.

[0031] The baffle 22 and the control board 30 are both located on the left side of the lower mold 2, and the baffle 22 is located on the left side of the control board 30. Its main function is that when the slider 15 is installed through the sliding action with the slide groove 14, the baffle 22 will contact the left side of the control board 30, so that the control board 30 drives the slide board 24 to push to the right, thereby achieving the effect of facilitating the installation of the slide board 24.

[0032] Among them, a slide groove 4 27 is opened inside the slide plate 24, and a slider 3 28 is slidably connected inside the slide groove 4 27. A limit plate 29 is fixedly installed on the left side of the slider 3 28, and the limit plate 29 is located on the left side of the baffle 22.

[0033] When the second injection molding is completed, the limit plate 29 is first installed through the sliding action of the slider three 28 and the slide groove four 27. At this time, when the connecting plate 19 is disassembled to the left side through the sliding action of the slider two 15 and the slide groove two 14, the slider two 15 will push the limit plate 29 to the left side. At the same time, since the limit plate 29 and the slide plate 24 are slidingly connected through the slider three 28 and the slide groove four 27, the slide plate 24 is pushed to the left side, thereby achieving the effect of displacement and disassembly of the slide plate 24.

[0034] Among them, a fixed block 31 is fixedly installed on the left side of the connecting plate 19, a connecting sleeve 32 is provided on the inner side of the fixed block 31, a clamping rod 33 is slidably connected inside the connecting sleeve 32, a limiting ring 36 is fixedly installed on the outer side of the clamping rod 33, a limiting ring 2 34 is fixedly installed on the outer side of the connecting sleeve 32, a spring 35 is fixedly installed in the middle of the limiting ring 36 and the limiting ring 2 34, and the spring 35 is sleeved on the outer side of the connecting sleeve 32 and the clamping rod 33.

[0035] The clamping rod 33 and the fixing block 31 are in a clamping connection. When the connecting sleeve 32 needs to be installed, the clamping rod 33 is pressed in the direction of the connecting sleeve 32 so that the clamping rod 33 and the fixing block 31 are clamped and then released. At this time, the connecting sleeve 32 is fixed to the left side of the connecting plate 19, thereby achieving a convenient connection effect.

[0036] Among them, a connecting rod 37 is fixedly installed above the connecting sleeve 32, and a fixing rod 38 is fixedly installed on one end of the connecting rod 37 away from the connecting sleeve 32. The fixing rod 38 is rotatably connected to the fixing block 2 39, and the fixing block 2 39 is fixedly connected to the upper mold 7.

[0037] When the starting cylinder 5 drives the upper mold 7 to move downward through the output shaft 6, the connecting rod 37 is supported outward by the rotation of the fixing rod 38 and the fixing block 39, so that the connecting sleeve 32 drives the connecting plate 19 to move to the left through the sliding action of the slider 15 and the slide groove 14 through the clamping action of the clamping rod 33 and the fixing block 1 31, so that when the first injection molding is performed, it is convenient for the connecting plate 19 to be located on the left side of the molding component 13, so as not to affect the first injection molding. At the same time, the material that needs secondary injection molding is placed in the installation bin 20. When the upper mold 7 is lifted upward by the action of the output shaft 6, the connecting plate 19 is reset, and then the clamping rod 33 is pressed inward to separate the clamping effect of the clamping rod 33 from the fixing block 1 31, so that when the upper mold 7 falls downward, secondary injection molding can be performed without driving the connecting plate 19 to move.

[0038] The bottom of the shaping component 13 is inclined, lower on the left and higher on the right. There are multiple connecting columns 25 and multiple top balls 26 , and the multiple connecting columns 25 and the multiple top balls 26 are all located at the bottom of the shaping component 13 .

[0039] When the slide plate 24 and the slide groove 3 23 slide to the left, the top ball 26 will be connected to the column 25 and will be driven to move to the left. At this time, since the bottom of the shaping component 13 is inclined, the top ball 26 will push the shaping component 13 upward after contacting the bottom of the shaping component 13, so as to facilitate demoulding.

[0040] Among them, there are multiple connecting chambers 16, multiple sliding rods 17 and multiple springs 18, and the multiple connecting chambers 16, multiple sliding rods 17 and multiple springs 18 are respectively located on the front and back sides of the shaping component 13.

[0041] Multiple sliding rods 17 and multiple connecting chambers 16 are respectively slidably connected, so that during injection molding, the bottom of the connecting plate 19 can be attached to the bracket 3 to facilitate injection molding. At the same time, multiple springs 18 provide elastic force to make the connecting plate 19 pop up, so that during the first injection molding, it is convenient for the connecting plate 19 to move and prevent it from being limited.

[0042] Among them, the limiting ring 21 is located directly above the shaping component 13, a material placement bin is placed inside the installation bin 20, and the pressing block 10 is located directly above the shaping component 13 and the installation bin 20.

[0043] The material placement bin facilitates positioning of the secondary injection material and improves the injection molding accuracy. At the same time, by being placed inside the installation bin 20, it can be disassembled and replaced at will, thereby achieving the effect of being able to inject materials of different shapes.

[0044] The working principle and use process of the present invention:

[0045] First, since the lower mold 2 and the bracket 3 are fixedly installed on the top of the base 1, the connecting block 4 is fixedly installed on the top of the bracket 3, the cylinder 5 is fixedly installed on the top of the connecting block 4, the output end of the cylinder 5 is fixedly installed with the output shaft 6, the bottom of the output shaft 6 is fixedly installed with the upper mold 7, the bottom of the upper mold 7 is fixedly installed with the telescopic shaft 8, the outer side of the telescopic shaft 8 is sleeved with a spring 9, and the bottom of the spring 9 is fixedly installed with a pressing block 10, starting the cylinder 5 can make the output shaft 6 drive the upper mold 7 to move up and down, so that the pressing block 10 can achieve the pressing effect through the connection between the telescopic shaft 8 and the spring 9;

[0046] Secondly, since a second slide groove 14 is provided inside the lower mold 2, a second slider 15 is slidably connected inside the second slide groove 14, a connecting bin 16 is provided inside the slider 15, a slide bar 17 is slidably connected inside the connecting bin 16, a connecting plate 19 is fixedly installed above the slide bar 17, a mounting bin 20 is provided inside the connecting plate 19, and a limiting ring 21 is fixedly installed inside the mounting bin 20, when it is necessary to perform secondary injection molding to put in the material, firstly, the material placement bin is put into the mounting bin 20, at this time, the mounting bin 20 limits the material placement bin to prevent the material placement bin from continuing to move downward, and at the same time, the material is located directly above the shaping component 13, and when the starting cylinder 5 drives the upper mold 7 to move downward for pressing through the output shaft 6, the material is kept in a fixed position, so as to achieve the effect of improving the accuracy of the secondary injection molding;

[0047] At the same time, a connecting rod 37 is fixedly installed above the connecting sleeve 32, and a fixing rod 38 is fixedly installed on the end of the connecting rod 37 away from the connecting sleeve 32. The fixing rod 38 is rotatably connected to the fixing block 2 39, and the fixing block 2 39 is fixedly connected to the upper mold 7. When the cylinder 5 is started to drive the upper mold 7 to move downward through the output shaft 6, the connecting rod 37 is supported outward by the rotation of the fixing rod 38 and the fixing block 2 39, so that the connecting sleeve 32 drives the connecting plate 19 through the slider 2 15 and the slide groove 2 through the clamping action of the clamping rod 33 and the fixing block 1 31. 14 is displaced to the left by the sliding action of the connecting plate 19, so that when the first injection molding is performed, the connecting plate 19 is conveniently located on the left side of the shaping component 13, so as not to affect the first injection molding. At the same time, the material required for the second injection molding is placed inside the mounting bin 20. When the upper mold 7 is lifted upward by the action of the output shaft 6, the connecting plate 19 is reset, and then the clamping rod 33 is pressed inwardly to separate the clamping effect of the clamping rod 33 from the fixing block 31, so that when the upper mold 7 falls downward, the second injection molding can be performed without causing the connecting plate 19 to be displaced.

[0048] Finally, a slide groove three 23 is opened inside the lower mold 2, and a slide plate 24 is slidably connected inside the slide groove three 23. At the same time, a connecting column 25 is fixedly installed above the slide plate 24, and a top ball 26 is fixedly installed above the connecting column 25. The top ball 26 is located at the bottom of the shaping component 13, and the bottom of the shaping component 13 is inclined with the left bottom and the right high. When the slide plate 24 slides with the slide groove three 23 to move to the left, the top ball 26 will be driven by the connecting column 25 to move to the left. At this time, since the bottom of the shaping component 13 is inclined, the top ball 26 will push the shaping component 13 upward after contacting the bottom of the shaping component 13, thereby achieving the effect of facilitating demoulding.
