Description

Technical Field

[0001] This application relates to the field of mold opening control technology, and in particular to a structure that facilitates control of the mold opening sequence. Background Technology

[0002] In the field of mechanical manufacturing, molds are tools used to shape objects. For molds composed of multiple layers of templates, they play a crucial role in industrial production, especially in the processing of special parts. With the continuous development of industry, the requirements for mold performance and function are also increasing. The ability to accurately control various operations of the mold is becoming increasingly important. Among these, controlling the mold opening sequence of multi-layer template molds is particularly critical in the processing of special parts, as it directly affects the processing quality and production efficiency.

[0003] In existing technologies, the opening operation of multi-layer molds is typically achieved by moving multiple layers together. However, in the production of special parts, this method reveals significant drawbacks. Because the processing of special parts requires specific sequence control of the mold opening sequence, the existing method cannot precisely control the movement order of each mold layer, making it difficult to meet the processing requirements of special parts. This can lead to parts that do not meet quality standards, thus affecting production efficiency and product quality. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this application provides a structure that facilitates control of the mold opening sequence. Through multi-component linkage design, it combines precise control of the mold opening sequence, automatic reset of the stop block, and linkage opening between the templates.

[0005] This application is achieved through the following technical solution:

[0006] A structure for conveniently controlling the mold opening sequence includes a first fixing block fixed on a first template, a second fixing block fixed on a second template, and a third fixing block fixed on a third template, arranged sequentially from top to bottom. The first fixing block has an abutment portion at its bottom. The second fixing block has a sliding hole in its middle, through which a stop block is slidably connected, and an elastic element providing a restoring force to the stop block is provided within the sliding hole. The third fixing block has a pushing portion adapted to the stop block. When the templates are engaged, the abutment portion is located below the stop block and has a set gap with the stop block in the vertical direction. After the abutment portion moves upward a set distance, it abuts against the bottom of the stop block, causing the second fixing block to move upward as well. After the second fixing block moves upward a set distance with the abutment portion, the pushing portion drives the stop block to disengage from the abutment portion, thereby causing the second fixing block to fall back to its original position.

[0007] By adopting the above technical solution, this structure can effectively control the mold opening sequence. The first, second, and third fixed blocks are arranged in sequence, with the abutting part cooperating with the blocking block. Initially, there is a set gap. After the abutting part moves up a set distance, it abuts against the blocking block, causing the second fixed block to move up. When the second fixed block moves up a certain distance, the pushing part causes the blocking block to disengage from the abutting part. Under the action of the elastic element, the second fixed block falls back to its original position, realizing orderly mold opening and ensuring that the mold opening process is stable, efficient, and controllable.

[0008] Optionally, the first fixing block is provided with a first bolt hole; the second fixing block is provided with a second bolt hole; and the third fixing block is provided with a third bolt hole.

[0009] By adopting the above technical solution, the first fixing block, the second fixing block and the third fixing block are respectively provided with the first bolt hole, the second bolt hole and the third bolt hole, which makes it easy to use bolts to firmly install each fixing block on the corresponding template, thereby enhancing the stability and reliability of the overall structure and enabling the structure that facilitates the control of the mold opening sequence to play a more stable role in the mold opening process.

[0010] Optionally, the lower end of the first fixing block is provided with a mating portion extending to the third fixing block, and the abutting portion is a protrusion provided at the lower end of the mating portion; the upper end of the protrusion is provided with a horizontally arranged abutting surface, and the side is provided with a guide slope.

[0011] By adopting the above technical solution, the docking part extends to the third fixing block, which allows the first fixing block and the third fixing block to form a more reasonable spatial layout and enhances structural stability; the abutment part is set as a protrusion at the lower end of the docking part, which facilitates the abutment function; the horizontal abutment surface at the upper end of the protrusion can stably abut against the bottom of the blocking block, driving the second fixing block to move upward, and the guide slope on the side can play a guiding role during docking, making the docking process smoother.

[0012] Optionally, the side of the blocking block is provided with a limiting block; the inner wall of the sliding hole is provided with a positioning groove that matches the limiting block.

[0013] By adopting the above technical solution, when the blocking block slides, the limiting block can move in the positioning groove, which plays a guiding and limiting role for the blocking block, preventing the blocking block from shifting or rotating in the sliding hole, ensuring that the blocking block slides smoothly in the sliding hole, and ensuring the stability and reliability of the entire mold opening sequence control structure.

[0014] Optionally, the limiting blocks are symmetrically arranged on both sides of the blocking block.

[0015] By adopting the above technical solution, limiting blocks are symmetrically arranged on both sides of the blocking block, which can cooperate with the positioning groove on the inner wall of the sliding hole to make the blocking block slide stably in the sliding hole, avoid the blocking block shaking or shifting, and ensure that the blocking block is accurately matched with the abutting part and the pushing part, thereby ensuring that the structure that is easy to control the mold opening sequence can be smoothly molded in the set sequence.

[0016] Optionally, the cross-section of the limiting block is square.

[0017] By adopting the above technical solution, it is convenient to control the mold opening sequence, and at the same time, the limiting block can effectively limit the sliding range and trajectory of the blocking block in the sliding hole, avoid the blocking block from shifting or rotating, ensure the stability and accuracy of the blocking block's movement, and thus ensure the reliability of the entire structure.

[0018] Optionally, the stop block has a positioning hole for fixing the elastic element at the middle of one end near the second template.

[0019] By adopting the above technical solution, the positioning hole can fix the elastic element, ensuring that the elastic element provides a stable reset force for the stop block, ensuring stable operation of the structure, and enabling the stop block to accurately reset when the external force is lost, which is beneficial for controlling the mold opening sequence.

[0020] Optionally, the blocking block is provided with a guide portion, which includes a guide slope and a vertical surface, and the lower end of the guide slope is connected to the vertical surface; the guide slope abuts against the pushing portion.

[0021] By adopting the above technical solution, a guide part and a guide slope and a vertical surface are set up, and the guide slope abuts against the pushing part, so that the pushing part can drive the blocking block to move more smoothly, thereby more smoothly realizing the blocking block disengaging from the contact part, ensuring that the second fixed block can fall back to reset in the set sequence, and thus more conveniently controlling the mold opening sequence.

[0022] Optionally, the upper end of the third fixing block is provided with a C-shaped groove extending to the first fixing block, and the opening of the C-shaped groove is adapted to the docking part; the pushing part is provided on the upper side of the C-shaped groove.

[0023] By adopting the above technical solution, a C-shaped groove extending to the first fixed block and adapted to the opening and docking part is set, making the layout of each component more reasonable and compact; the pushing part is set at the upper side of the C-shaped groove, which can better cooperate with the blocking block, ensuring that the pushing part drives the blocking block to disengage from the contact with the abutment part in the appropriate position, thereby causing the second fixed block to fall back and reset, achieving the purpose of conveniently controlling the mold opening sequence.

[0024] Optionally, the docking part includes an upper connecting part and a lower connecting part. The upper connecting part is provided with a plurality of first fixing holes, and the lower connecting part is provided with a plurality of second fixing holes adapted to the first fixing holes. The upper connecting part and the lower connecting part are fixed by a locking rod passing through the first fixing holes and the second fixing holes.

[0025] By adopting the above technical solution, the docking part is divided into an upper connecting part and a lower connecting part, and a locking rod is used to fix it through the first fixing hole of the upper connecting part and the second fixing hole of the lower connecting part. This facilitates the assembly and disassembly of the docking part, and also facilitates subsequent maintenance, replacement of parts, and adjustment of the height of the docking part. Combined with a structure that facilitates the control of the mold opening sequence, the combination of the components of this structure is more flexible, further ensuring the normal operation of the mold opening sequence control function.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. This application achieves automatic positioning and resetting during template engagement through the linkage design of the abutment part, the stop block and the push part.

[0028] 2. The guide section in this application, through the cooperation of the guide slope and the vertical surface, allows the blocking block to move smoothly upward along the pushing section, ensuring precise disengagement from the abutment section.

[0029] 3. This application uses a limiting block and a positioning groove to prevent the blocking block from disengaging from the sliding hole, thereby enhancing sliding stability and limiting the displacement range. Attached Figure Description

The three fixed blocks 6 are provided with a pushing part 61 that is adapted to the blocking block 511; when the templates are engaged, the abutting part 41 is located below the blocking block 511 and there is a set gap between it and the blocking block 511 in the vertical direction; wherein, after the abutting part 41 moves up a set distance, it can abut against the bottom of the blocking block 511 and drive the second fixed block 5 to move up accordingly. After the second fixed block 5 moves up a set distance with the abutting part 41, the pushing part 61 can drive the blocking block 511 to disengage from the contact with the abutting part 41, thereby causing the second fixed block 5 to fall back to its original position.

[0045] Specifically, refer to Figure 2 The first fixing block 4 has a first bolt hole 42; the second fixing block 5 has a second bolt hole 52; and the third fixing block 6 has a third bolt hole 62. The first bolt hole 42, the second bolt hole 52, and the third bolt hole 62 can all adopt a common circular through hole structure. Their function is to firmly fix the first fixing block 4 to the first template 1, the second fixing block 5 to the second template 2, and the third fixing block 6 to the third template 3 respectively by bolts.

[0046] Reference Figures 2-4 The upper end of the third fixing block 6 is provided with a C-shaped groove 63 extending to the first fixing block 4, and the opening of the C-shaped groove 63 is adapted to the docking part 43; the pushing part 61 is provided on the upper side of the C-shaped groove 63. The C-shaped groove 63 not only provides the docking part 43 with a space for movement, but also plays a certain role in protecting and limiting the docking part 43.

[0047] Reference Figures 5-6 The lower end of the first fixing block 4 is provided with a docking portion 43 extending to the third fixing block 6. The abutment portion 41 is a protrusion 431 provided at the lower end of the docking portion 43. The upper end of the protrusion 431 is provided with a horizontally arranged abutment surface 4311, and the side is provided with a guide slope 4312. The protrusion 431 is provided at the lower end of the docking portion 43, and its upper end is provided with a horizontally arranged abutment surface 4311, and the side is provided with a guide slope 4312. The abutment surface 4311 is used to abut against the bottom of the stop block 511 to transmit upward force; the guide slope 4312 can play a guiding role in the abutment process, making the abutment smoother.

[0048] Reference Figures 6-8The abutment block 511 has a limiting block 5111 on its side; the inner wall of the sliding hole 51 has a positioning groove 513 that matches the limiting block 5111. The cooperation between the limiting block 5111 and the positioning groove 513 ensures that the abutment block 511 slides in the sliding hole 51 and prevents the abutment block 511 from coming out of the sliding hole 51. The limiting blocks 5111 are symmetrically arranged on both sides of the abutment block 511.

[0049] Reference Figure 8 The limiting block 5111 has a square cross-section. A positioning hole 5112 for fixing the elastic element 512 is provided in the middle of one end of the stop block 511 near the second template 2. The elastic element 512 is generally a spring. When the stop block 511 slides under the action of an external force, the spring is compressed. After the external force disappears, the spring force will cause the stop block 511 to return to its original position. A guide portion 5113 is provided on the stop block 511. The guide portion 5113 includes a guide inclined surface 5114 and a vertical surface 5115. The lower end of the guide inclined surface 5114 is connected to the vertical surface 5115. The guide inclined surface 5114 abuts against the pushing part 61. The guide inclined surface 5114 abuts against the pushing part 61, guiding the stop block 511 to slide when pushed by the pushing part 61.

[0050] The implementation principle of this embodiment is as follows: By cleverly designing the first fixing block 4, the second fixing block 5, and the third fixing block 6, as well as the mating components between them, and utilizing the synergistic effect of the abutment part 41, the blocking block 511, the pushing part 61, and the elastic element 512, precise control of the mold opening sequence is achieved. Compared with traditional mechanical locking devices, hydraulic systems, and existing spring technologies, this structure is simpler to operate, reduces manual intervention, lowers the risk of operational errors, and improves the accuracy of the mold opening sequence. At the same time, its structure is relatively simple, its cost is low, and its maintenance is easier. It can be applied to various types of molds, especially complex mold production scenarios with strict requirements on the mold opening sequence. It has strong practicality and innovation, and is an effective improvement on existing mold opening sequence control technology.

[0051] Example 2

[0052] Reference Figures 9-11The difference between this embodiment and Embodiment 1 is that the docking part 43 includes an upper connecting part 432 and a lower connecting part 433. The upper connecting part 432 is provided with a plurality of first fixing holes 4321, and the lower connecting part 433 is provided with a plurality of second fixing holes 4331 that are adapted to the first fixing holes 4321. The upper connecting part 432 and the lower connecting part 433 are fixed by a locking rod 4322 that passes through the first fixing holes 4321 and the second fixing holes 4331. This split design facilitates installation and maintenance, and the fixing by the locking rod 4322 can ensure the overall strength of the docking part 43; at the same time, the height of the docking part 43 can be adjusted, thereby adjusting the gap height between the abutment part 41 and the stop block 511.

[0053] The implementation principle of this embodiment is as follows: by designing the docking part 43 as a split upper connecting part 432 and lower connecting part 433, and fixing it with locking rod 4322, the docking part 43 can be installed and maintained while ensuring overall strength, thus improving the practicality and maintainability of the structure, thereby better realizing precise control of the mold opening sequence and meeting the needs of complex mold production.
