Description

Technical Field

[0001] The invention relates to the technical field of optical module die-casting equipment, in particular to a zinc-aluminum alloy die-casting mold for an optical module. Background Art

[0002] Modern communications are all transmitted by optical fiber cables, and the terminals send and receive electrical signals. The optical module has become an indispensable conversion device for the photoelectric signals at both ends. Generally, the base and outer cover of the optical module are die-cast. Die-casting has the advantages of high dimensional accuracy and low process cost. It is currently the most commonly used processing technology for optical module housings. The traditional alloys for die-casting of optical modules include No. 3, No. 4 and No. 5 zinc alloys, as well as A360, A380, ADC10, and ADC12 aluminum alloys.

[0003] The die casting of optical modules not only includes the die casting process, but also requires cooling and dewatering operations. During the die casting process, since the die castings of optical modules are relatively small, the die casting molds of general processes will die cast multiple molded parts at a time, and the multiple molded parts are connected by water nozzles to form a whole. After spray cooling and demolding, the integrated molded parts are taken out to the stamping mold position for stamping and dewatering operations. In actual production, for molded parts with large size and a small number of die-cast molded parts at a time, the above-mentioned traditional process can be used. However, in order to improve production efficiency, the molds are currently die-cast with a large number of molded parts at a time. After demolding, the molded parts are connected to each other with water nozzles in the shape of a mesh disk. This will cause many problems in the actual production process: when taking the material, generally after demolding, the surface temperature of the molded part is high, and soft-contact suction cup material taking is generally not used. Aluminum-zinc alloy is non-magnetic, so generally only a manipulator can be used to clamp the high-temperature molded parts. Although the general clamping manipulator can be set with multi-point clamping, it is difficult to face the mesh disk-shaped molding. In the actual clamping process, the molded parts can only be clamped at multiple points such as the four corners and the center. However, the nozzles connecting these molded parts are narrow and slender, and are easy to bend or fall off directly. Therefore, in the actual clamping process, it is easy for individual molded parts to fall and bend, or the connected nozzles to break, causing the molded parts to fall off directly. This requires the inspection personnel to pay attention to the demolding and material collection process on the actual production line. In addition, it is precisely because of the above problems that during cooling, due to the different temperature differences in the cooling order of each area and the inconsistent cooling efficiency, the entire mesh-shaped molded part will be deformed after passing through the cooling channel. The deformation here is mainly caused by the deformation of the cooling of the connecting nozzles, which drives the connected molded parts to change their positions. This leads to the problem of misalignment in the subsequent stamping and de-sprucing operations, and it is necessary to arrange additional operators to align multiple molded parts on the stamping station. This results in the original automated production line being equipped with multiple inspection operators to operate, which increases production costs and affects the overall production efficiency.

For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0038] See also Figure 1-Figure 13The present invention provides a technical solution: a zinc-aluminum alloy die-casting mold for an optical module, comprising a die-casting mold table 1, a clamping assembly, a cooling assembly and a stamping mold table 2, the die-casting mold table 1 comprising a die-casting mold assembly 10, the die-casting mold assembly 10 is used for a demolding member 12 of a die-casting optical module, the demolding member 12 comprises a plurality of moldings 13 and a sprue edge 14 connecting the moldings 13, the stamping mold table 2 comprises a stamping mold assembly 20, the cooling assembly is arranged between the die-casting mold table 1 and the stamping mold table 2 processes and are respectively equipped with a clamping assembly;

[0039] The material clamping assembly and the cooling assembly are integrated on the transfer cooling platform 3. The transfer cooling platform 3 includes a cooling box cover 30. The cooling box cover 30 is provided with a storage channel 38. The bottom of the cooling box cover 30 is provided with a rotating and lifting driving base mechanism.

[0040] The clamping assembly includes an upper pressing plate 5 and a drag plate 4 respectively arranged at upper and lower horizontal positions of the cooling box cover 30, the drag plate 4 is used to drag the demoulding member 12 from the bottom, and the upper pressing plate 5 is used to press the demoulding member 12 from the top, and the cooling assembly is integrated around the inner wall of the cooling box cover 30;

[0041] The cooling box cover 30 is provided with a cooling box cover 30 for the carriage 4 and the upper pressing plate 5 to extend out, and the carriage 4 and the upper pressing plate 5 are respectively driven by a set of screw drive components 31 to move along the cooling box cover 30; a downward pressing electric cylinder 35 is provided on the top of the cooling box cover 30 to drive the upper pressing plate 5 to move vertically downward;

[0042] The carriage 4 and the upper pressing plate 5 both include a connecting box plate 40, and a plurality of spaced inserting plates 41 are installed on the side wall of the connecting box plate 40. A plurality of limiting metal blocks 42 for limiting the formed part 13 are vertically slidably arranged on the surface of each inserting plate 41. A protruding driving mechanism for driving the plurality of limiting metal blocks 42 to protrude is arranged in the inserting plate 41. A selective opening mechanism is arranged on one side of each limiting metal block 42. The limiting metal block 42 on the carriage 4 protrudes on the side of the formed part 13, and the limiting metal block 42 on the upper pressing plate 5 protrudes on the force-bearing surface of the formed part 13.

[0043] The bottom molds of the die-casting mold assembly 10 and the stamping mold assembly 20 are provided with an extended demoulding and lifting assembly 11 for each molded part 13 .

[0044] During operation, the die-casting mold assembly 10 is first die-cast and the additionally provided extended demoulding lifting assembly 11 is used to lift the demoulding part 12. The bottom of the demoulding part 12 and the bottom mold of the die-casting mold assembly 10 are increased in height to facilitate the insertion of the carriage 4. Then the carriage 4 and the upper pressing plate 5 are respectively moved toward the die-casting mold assembly 10 through the screw drive assembly 31. The carriage 4 is inserted from the bottom and slowly lifted and dragged by the driving base mechanism to drag the demoulding part 12, while the upper pressing plate 5 is moved to the top of the demoulding part 12. The demoulding part 12 is pressed down as a whole by a separate downward pressing electric cylinder 35. In this way, the demoulding part 12 can be clamped and dragged as a whole and sent into the cooling box cover 30 for cooling. Both movement and rotation can ensure the stability of the demoulding part 12, and there will be no problem of bending of the nozzle edge 14 or direct falling of a molded part 13 due to uneven force.

[0045] In addition, before the action of the carriage 4 and the upper pressing plate 5, the opening mechanism is selected to determine which limiting metal blocks 42 are specifically driven by the protruding driving mechanism to perform the protruding action according to the overall forming state of the demolding part 12, that is, the distribution of the molded parts 13. Here, the carriage 4 is mainly used to hold up the demolding part 12 and limit it. The limiting metal block 42 on the carriage 4 is raised on the side of the molded part 13 to provide a lateral limiting protection for the molded part 13, and the limiting metal block 42 on the upper pressing plate 5 is mainly used to press the molded part 13 at a fixed point. Therefore, the limiting metal block 42 at the force-bearing surface position of the rotating molded part 13 is raised. As a result, the cooperation between the carriage 4 and the upper pressing plate 5 is improved. It can ensure the accurate positioning of each molded part 13 of the demolding part 12 during transportation, and when cooling in the cooling box cover 30, even if the cooling efficiency is inconsistent and different nozzle edges 14 are deformed due to cooling, the overall contour of the demolding part 12 will not be changed due to the cooperation of the carriage 4 and the upper pressing plate 5. The position of each molded part 13 on the demolding part 12 is within a reasonable error range. When the carriage 4 and the upper pressing plate 5 transport the demolding part 12 as a whole to the position of the stamping die assembly 20, there is no need to consider the problem of inaccurate position of the molded part 13 caused by the deformation of the demolding part 12. Multiple molded parts 13 can be accurately placed in the stamping station of the stamping die assembly 20 for stamping operation;

[0046] Here, the limiting metal blocks 42 of the drag plate 4 and the upper pressure plate 5 adopt the same set of action mechanisms, which is more convenient for driving and adjustment, and each limiting metal block 42 can be selectively opened, so that the protruding position can be appropriately adjusted according to the size of the molded part 13, thereby adapting to the molding positioning of various molded parts 13, greatly improving the adaptability of the product.

[0047] The protruding driving mechanism includes a main air passage 44 opened in each plug plate 41, a lifting air cavity 46 is opened in the plug plate 41 at a corresponding position of each limiting metal block 42, a wind pressure slide plate 47 is vertically slidably installed in the lifting air cavity 46, the limiting metal block 42 is slidably inserted into the lifting air cavity 46 and fixed on the top of the wind pressure slide plate 47, the lifting air cavity 46 is communicated with the main air passage 44 through the side air passage 45, a plurality of air pipe joints 49 communicating with the corresponding main air passages 44 are arranged on the connecting box plate 40, and a high-pressure air supply system 34 for supplying air to the air pipe joints 49 is arranged on the top of the cooling box cover 30;

[0048] The selective opening mechanism includes a ventilation metal valve column 43 provided on one side of each limiting metal block 42, the ventilation metal valve column 43 is sealed and slidably inserted into the side air channel 45, and a column connecting port 48 for connecting the main air channel 44 and the lifting air cavity 46 is provided at the upper side of the bottom of the ventilation metal valve column 43;

[0049] The ventilation metal valve column 43 is set to a normally closed state. The top of the ventilation metal valve column 43 in the normally closed state is flush with the top surface of the plug plate 41. The column connecting port 48 at the bottom of the ventilation metal valve column 43 is misaligned with the side air channel 45. The side air channel 45 at the corresponding position is closed. The wind pressure slide plate 47 is located at the bottom through the built-in spring, and the top end of the limiting metal block 42 is flush with the top surface of the plug plate 41.

[0050] During operation, the protruding driving mechanism provided here adopts the driving mode of high-pressure gas, which can quickly and simply control the multiple limiting metal blocks 42 on the drag plate 4 and the upper pressure plate 5. The high-pressure gas supply system 34 supplies high-pressure gas to the main air channel 44 of each plug plate 41 independently through the air pipe and the air pipe joint 49. The high-density high-pressure gas in the main air channel 44 flows into each lifting air cavity 46 through the side air channel 45 and acts on the wind pressure slide plate 47. The wind pressure slide plate 47 is pressurized to squeeze out the gas upward and drive the limiting metal block 42 to move upward, thereby completing the protruding action of the limiting metal block 42. The opening mechanism selected here adopts a simple ventilation metal valve column 43 to cooperate with the misplaced column connecting port 48, and the operator can simply press and pull it out. It is intuitive to select whether the limiting metal block 42 at this position is protruding. When the ventilation metal valve column 43 is sunken and flush, the high-pressure gas in the main airway 44 cannot flow into the lifting air cavity 46, and the limiting metal block 42 is also in a sunken and flush state. Then, when the limiting metal block 42 and the ventilation metal valve column 43 at this position are not protruding, they will not affect the flatness of the surface of the plug plate 41, reducing the impact of the protrusion of the limiting metal block 42 or the ventilation metal valve column 43. In addition, the drag plate 4 and the upper pressure plate 5 here are made of metal as a whole, which will not be affected by high temperature, and the pneumatic drive method can ensure that the action end is minimized by the impact of high temperature, the overall service life is long, the operation is more stable, and the overflowed gas can also perform local fixed-point cooling on the demolding part 12.

[0051] The wind pressure slide plate 47 and the limiting metal block 42 are both installed in a gap sliding manner. When the side air passage 45 is connected, the high-pressure gas is ejected outward from the gap between the wind pressure slide plate 47 and the limiting metal block 42.

[0052] During operation, the limiting metal block 42 and the wind pressure slide plate 47 do not use the traditional sealing method, but a ventilation gap is specially left to allow the high-pressure gas to overflow directly. As long as sufficient air pressure is guaranteed, the air pressure can ensure the action of the top wind pressure slide plate 47. At the same time, each molded part 13 can be ventilated at a fixed point from the position of the limiting metal block 42 to quickly pre-dissipate heat, which greatly improves the overall cooling efficiency of the demolding part 12.

[0053] Among them, the screw drive assembly 31 corresponding to the carriage 4 is fixedly installed on the inner wall of the cooling box cover 30 by multiple support frames 32, the screw drive assembly 31 corresponding to the upper pressure plate 5 is vertically slidably mounted just above the carriage 4 by multiple horizontally arranged support frames 32, and the downward pressing electric cylinder 35 is invertedly installed on the top of the cooling box cover 30, and the telescopic end of the downward pressing electric cylinder 35 slides into the cooling box cover 30 and is fixedly connected to the screw drive assembly 31 corresponding to the upper pressure plate 5;

[0054] During operation, since the drag plate 4 is integrally connected to the cooling box cover 30, the lifting and lowering of the drag plate 4 is completed by the driving base mechanism, and the upper pressure plate 5 needs to be completed by pressing the electric cylinder 35 downward. Therefore, the screw drive assembly 31 connected to the upper pressure plate 5 needs to be displaced in the vertical direction. Therefore, the support frame 32 corresponding to the upper pressure plate 5 and the inner wall of the cooling box cover 30 adopt a vertical sliding connection.

[0055] The driving base mechanism includes a lifting base 37, a rotating motor 36 is fixed to the top telescopic end of the lifting base 37, and the rotating end of the rotating motor 36 is fixedly connected to the cooling box cover 30;

[0056] During operation, the rotating motor 36 drives the cooling box cover 30 to rotate as a whole, so as to facilitate the transfer of the demolding part 12 between the die-casting mold platform 1 and the stamping mold platform 2, and the lifting base 37 facilitates the adjustment of the overall height of the cooling box cover 30.

[0057] The cooling assembly includes a plurality of jet holes respectively arranged on the inner wall of the cooling box cover 30, and a cooling air supply system 33 for supplying air to the plurality of jet holes is arranged on the top of the cooling box cover 30;

[0058] During operation, the cooling air supply system 33 can be set to cool the intake air in a compression cooling manner and then cool the demoulding member 12 clamped between the carriage 4 and the upper pressing plate 5 from all sides through the air injection holes.

[0059] The side wall of the connecting box plate 40 is provided with a mounting slot for adjusting the extension length and spacing of the plug plate 41, and the plug plate 41 is fixed in the mounting slot by bolt threads;

[0060] During operation, the set installation slots can change the length and spacing of each plug plate 41, so as to adapt to the spacing specifications of different molded parts 13, and ensure that each plug plate 41 can be adjusted to match the distribution of the molded parts 13, and ensure that the plug plate 41 can be inserted into the spacing of the molded parts 13 without being interfered by the extended demolding lifting assembly 11.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
