Description

Technical Field

[0001] The present invention relates to the technical field of detonator production equipment, and particularly to a base detonator transfer die device and a transfer die machine. Background Art

[0002] A detonator is the main initiating material in blasting engineering, and its function is to generate initiating energy to detonate various explosives, detonating cords or detonating pipes. Detonators are generally divided into electric detonators and percussion detonators. The production process of detonators usually includes two links: filling and assembling. Filling is to press various initiating agents and components into the detonator shell to make a base detonator, and assembling is to firmly combine the ignition element, delay element, etc. with the base detonator to produce a finished detonator.

[0003] After the production of the base detonator is completed, in order to improve the subsequent filling efficiency, it is necessary to transfer the base detonator to a target mold with a different arrangement and a higher accommodation density. In the related art, the gravity of the base detonator is used to transfer the detonator from one mold to another. However, the dropping height of the base detonator is relatively large, which is likely to detonate the base detonator, and the safety factor during the transfer process is not high. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. For this purpose, the present invention provides a base detonator transfer die device, which can reduce the dropping height of the base detonator during the transfer process and improve the safety factor of the transfer process.

[0005] The present invention also provides a transfer die machine with the above base detonator transfer die device.

[0006] The base detonator transfer die device according to the first aspect embodiment of the present invention is used to transfer the base detonator in the mold to be transferred to the target mold, and includes:

[0007] A first runner seat assembly, including a first runner seat and a first opening and closing assembly. The first runner seat is provided with a plurality of first through holes extending in the vertical direction. Each first through hole is used to receive the base detonator in the mold to be transferred. Each first through hole includes a first upper hole opening and a first lower hole opening. The first opening and closing assembly includes a first opening and closing plate and a first driving assembly. The first driving assembly is used to drive the first opening and closing plate to move to close or open the first lower hole opening of each first through hole.

[0008] The second runner base assembly includes a second runner base and a second opening and closing assembly. The second runner base is located below the first runner base. The second runner base is provided with a plurality of second through holes extending in the up and down direction. Each of the second through holes is used to transfer the base detonators to the target mold. The number of the first through holes is equal to the number of the second through holes. Each of the second through holes includes a second upper orifice and a second lower orifice. The second upper orifice of each of the second through holes can be in one-to-one communication with the first lower orifice of each of the first through holes. The arrangement of the second lower orifices of each of the second through holes on the bottom surface of the second runner base is different from the arrangement of the first upper orifices of each of the first through holes on the top surface of the first runner base. The second opening and closing assembly includes a second opening and closing plate and a second driving assembly. The second driving assembly is used to drive the second opening and closing plate to move so as to close or open the second lower orifice of each of the second through holes.

[0009] The base detonator transfer mold device according to the embodiment of the present invention has at least the following beneficial effects: The plurality of first through holes of the first runner base are used to receive the base detonators in the mold to be transferred. The second runner base is located below the first runner base. Each of the second through holes of the second runner base is used to transfer the base detonators to the target mold. The second upper orifice of each of the second through holes can be in one-to-one communication with the first lower orifice of each of the first through holes. Thus, when the second upper orifice of each of the second through holes is in one-to-one communication with the first lower orifice of each of the first through holes, the base detonators can pass through the first runner base and the second runner base in sequence and be transferred to the target mold. At the same time, the arrangement of the second lower orifices of each of the second through holes on the bottom surface of the second runner base is different from the arrangement of the first upper orifices of each of the first through holes on the top surface of the first runner base, that is, through the conversion of the first through holes and the second through holes, the number of the base detonators does not change, but the arrangement is changed. Thus, the base detonators can be transferred to the target mold with a different arrangement and a higher accommodation density as required. The first driving assembly is used to drive the first opening and closing plate to move so as to close or open the first lower orifice of each of the first through holes. The second driving assembly is used to drive the second opening and closing plate to move so as to close or open the second lower orifice of each of the second through holes. Thus, when the base detonators fall from the mold to be transferred into the first runner base, they will be blocked by the first opening and closing plate. When the base detonators fall from the first runner base into the second runner base, they will be blocked by the second opening and closing plate. Finally, the base detonators fall from the second runner base into the target mold. During the entire falling process, the falling height of the base detonators is divided into three sections. The single falling height is small, the probability of the base detonators being detonated is lower, and the safety factor of the transfer process is higher.

Each of the fourth through holes includes a fourth upper orifice, and at least a part of the fourth upper orifices can be in one-to-one communication with at least a part of the second lower orifices of the second through holes;

[0017] A lifting assembly, including a positioning platform and a lifting driving component. The positioning platform is used to place the target die, the positioning platform is located below the guiding die, the lifting driving component is installed on the mounting frame, and the lifting driving component is used to drive the positioning platform to move in the up and down direction so that the positioning platform approaches or moves away from the guiding die.

[0055] In the description of the present invention, the descriptions with reference to terms such as "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples", etc. mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic descriptions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0056] Referring to Figures 1 to 6 , a base detonator transfer die device according to an embodiment of the first aspect of the present invention is used to transfer base detonators in a to-be-transferred die to a target die 600 (referring to Figure 1 ). The base detonator transfer die device includes a first runner base assembly 100 and a second runner base assembly 300. The first runner base assembly 100 includes a first runner base 110 and a first opening and closing assembly 120. The first runner base 110 is provided with a plurality of first through holes 111 extending in the up and down direction. Each first through hole 111 is used to receive base detonators in the to-be-transferred die, and each first through hole 111 includes a first upper orifice and a first lower orifice. The first opening and closing assembly 120 includes a first driving assembly 121 and a first opening and closing plate 122 (referring to Figure 5 ), and the first driving assembly 121 is used to drive the first opening and closing plate 122 to move to close or open the first lower orifice of each first through hole 111.

[0057] The second runner base assembly 300 includes a second runner base 310 and a second opening and closing assembly 320. The second runner base 310 is located below the first runner base 110. The second runner base 310 is provided with a plurality of second through holes 311 extending in the up and down direction. Each second through hole 311 is used to transfer the base detonators to the target mold 600. The number of the first through holes 111 is equal to the number of the second through holes 311. Each second through hole 311 includes a second upper orifice and a second lower orifice. The second upper orifice of each second through hole 311 can be in one-to-one communication with the first lower orifice of each first through hole 111. The arrangement of the second lower orifices of each second through hole 311 on the bottom surface of the second runner base 310 is different from the arrangement of the first upper orifices of each first through hole 111 on the top surface of the first runner base 110. The second opening and closing assembly 320 includes a second opening and closing plate 322 and a second driving assembly 321. The second driving assembly 321 is used to drive the second opening and closing plate 322 to move so as to close or open the second lower orifices of each second through hole 311.

[0058] Combined with the above, the plurality of first through holes 111 of the first runner base 110 are used to receive the base detonators in the mold to be transferred. The second runner base 310 is located below the first runner base 110. Each second through hole 311 of the second runner base 310 is used to transfer the base detonators to the target mold 600. The second upper orifice of each second through hole 311 can be in one-to-one communication with the first lower orifice of each first through hole 111. Thus, when the second upper orifice of each second through hole 311 is in one-to-one communication with the first lower orifice of each first through hole 111, the base detonators can sequentially pass through the first runner base 110 and the second runner base 310 and be transferred to the target mold 600. At the same time, the arrangement of the second lower orifices of each second through hole 311 on the bottom surface of the second runner base 310 is different from the arrangement of the first upper orifices of each first through hole 111 on the top surface of the first runner base 110, that is, through the conversion of the first through hole 111 and the second through hole 311, the number of the base detonators remains unchanged, but the arrangement is changed. Thus, the base detonators can be transferred to the target mold 600 with a different arrangement and a higher accommodation density as required.

[0059] The first driving component 121 is used to drive the first opening and closing plate 122 to move, so as to close or open the first lower orifices of the first through holes 111. The second driving component 321 is used to drive the second opening and closing plate 322 to move, so as to close or open the second lower orifices of the second through holes 311. Thus, when the base detonators fall from the mold to be transferred into the first runner block 110, they will be blocked by the first opening and closing plate 122. When the base detonators fall from the first runner block 110 into the second runner block 310, they will be blocked by the second opening and closing plate 322. Finally, the base detonators fall from the second runner block 310 into the target mold 600. During the entire falling process, the falling height of the base detonators is divided into three segments. The single falling height is small, the probability of the base detonators being detonated is lower, and the safety factor of the transfer process is higher.

[0060] It should be noted that the first through holes 111 extend in the up and down direction, including not only the case of extending in the vertical direction, but also the case of extending obliquely downward (that is, when the first through holes 111 extend downward, they also extend forward or backward, etc.). The same meaning applies to other extensions in the up and down direction.

[0061] It should be noted that the arrangement of the second lower orifices of the second through holes 311 on the bottom surface of the second runner block 310 is different from the arrangement of the first upper orifices of the first through holes 111 on the top surface of the first runner block 110. That is, the projection of the first upper orifices of the first through holes 111 on the bottom surface of the second runner block 310 will not coincide with the second lower orifices of the second through holes 311 no matter how it is rotated or translated. By changing the arrangement of the second lower orifices of the second through holes 311 on the bottom surface of the second runner block 310, the arrangement of the base detonators when flowing out of the second through holes 311 can be changed, so as to obtain the desired arrangement.

[0062] Specifically, the arrangement of the first upper orifices of the first through holes 111 on the top surface of the first runner block 110 is a rhombus arrangement (refer to Figure 3 ), that is, there are 9 rows in the front and back directions, among which 5 rows have 6 first through holes 111, and the other 4 rows have 5 first through holes 111, with a total of 50 first through holes 111. The arrangement of the second lower orifices of the second through holes 311 on the bottom surface of the second runner block 310 is a matrix arrangement (appropriately refer to Figure 4 ), that is, there are 5 rows in the front and back directions, and each row has 10 second through holes 311, with a total of 50 second through holes 311. Among them, the first through holes 111 arranged in a 4*5 pattern are inclined forward or backward, so that each row of the first through holes 111 arranged in a 5*6 pattern inserts 4 first through holes 111, thus becoming a 5*10 arrangement, and then docking with the second through holes 311.

[0063] Specifically, the first driving assembly 121 includes a first cylinder. The first cylinder includes a cylinder block and a piston rod. The piston rod can extend out of the cylinder block or retract into the cylinder block. The cylinder block of the first cylinder is fixedly connected to the frame 500, and the piston rod of the first cylinder is fixedly connected to the first opening and closing plate 122. After the first cylinder is connected to the air source and operates, it can drive the first opening and closing plate 122 to move linearly. In addition, the first driving assembly 121 can also include a linear motor. The linear motor includes a stator and a mover. The stator is fixedly connected to the frame 500, and the mover is fixedly connected to the first opening and closing plate 122. After the linear motor is powered on and operates, it can drive the first opening and closing plate 122 to move linearly.

[0064] Referring to Figure 4 and Figure 5 , in some embodiments of the present invention, the base detonator transfer die device further includes a third runner seat assembly 200. The third runner seat assembly 200 includes a third runner seat 210 and a third opening and closing assembly. The third runner seat 210 is located between the first runner seat 110 and the second runner seat 310. The third runner seat 210 is provided with a plurality of third through holes 211 extending in the up and down direction. The number of the third through holes 211 is equal to the number of the first through holes 111. Each of the third through holes 211 includes a third upper orifice and a third lower orifice. The third upper orifice of each of the third through holes 211 can be in one-to-one communication with the first lower orifice of each of the first through holes 111, and the third lower orifice of each of the third through holes 211 can be in one-to-one communication with the second upper orifice of each of the second through holes 311. The third opening and closing assembly includes a third opening and closing plate and a third driving assembly. The third driving assembly is used to drive the third opening and closing plate to move so as to close or open the third lower orifice of each of the third through holes 211.

[0065] Limited by the length of the base detonator, the spacing of the first through holes 111, and the spacing of the second through holes 311, the arrangement of the second through holes 311 is restricted. By providing the third runner seat 210, which is located between the first runner seat 110 and the second runner seat 310, the conversion stroke of the base detonator can be increased, and the arrangement of the base detonator after transfer die can be expanded. At the same time, by providing the third opening and closing assembly, the base detonator can still maintain a small drop height.

[0066] It should be noted that the structure of the third opening and closing assembly is similar to that of the first opening and closing assembly 120, and will not be repeated here.

[0067] Specifically, referring to Figure 4, a third slot 212 is provided between the third runner seat 210 and the second runner seat 310. A third driving assembly drives a third opening and closing plate to insert into the third slot 212 to close the third lower orifices of the third through holes 211, and the third driving assembly drives the third opening and closing plate to disengage from the third slot 212 to open the third lower orifices of the third through holes 211. The third slot 212 can be opened at the lower end of the third runner seat 210, or a gap is provided between the third runner seat 210 and the second runner seat 310 to form the third slot 212.

[0068] Referring to Figure 4 , in some embodiments of the present invention, the inner diameter of the second through hole 311 gradually decreases from top to bottom. Thus, when the base detonator enters the second through hole 311, the second through hole 311 can better receive the base detonator and the base detonator is not easily stuck; at the same time, the inner diameter of the second lower orifice of the second through hole 311 is smaller, which can better restrict the falling position of the base detonator and make the base detonator accurately fall into the target mold 600 (referring to Figure 1 ).

[0069] Referring to Figure 4 , in some embodiments of the present invention, a first slot 112 is provided between the first runner seat 110 and the second runner seat 310. A first driving assembly 121 is used to drive a first opening and closing plate 122 to insert into the first slot 112 to close the first lower orifices of the first through holes 111, and the first driving assembly 121 is used to drive the first opening and closing plate 122 to disengage from the first slot 112 to open the first lower orifices of the first through holes 111.

[0070] Thus, by providing the first slot 112, it is convenient for the first opening and closing plate 122 to open or close the first lower orifices of the first through holes 111. At the same time, the first slot 112 can guide and limit the movement of the first opening and closing plate 122.

[0071] Specifically, the first slot 112 can be opened at the lower end of the first runner seat 110, or a gap is provided between the first runner seat 110 and the second runner seat 310 to form the first slot 112.

[0072] Referring to Figures 7 to 9 , in some embodiments of the present invention, the base detonator transfer mold device further includes a receiving assembly 400. The receiving assembly 400 includes a guiding mold assembly 410 and a lifting assembly 420. The guiding mold assembly 410 includes a guiding mold 411 and a mounting frame 412. The mounting frame 412 is used to place the target mold 600, and the guiding mold 411 is fixedly connected to the mounting frame 412. The guiding mold 411 is provided with a plurality of fourth through holes 416 extending in the up and down direction. Each fourth through hole 416 includes a fourth upper orifice, and at least a part of the fourth upper orifices can be in one-to-one communication with at least a part of the second lower orifices of the second through holes 311.

[0073] The lifting assembly 420 includes a positioning platform and a lifting drive assembly. The positioning platform is used to place the target mold 600. The positioning platform is located below the guiding mold 411. The lifting drive assembly is installed on the mounting frame 412. The lifting drive assembly is used to drive the positioning platform to move in the up and down direction so that the positioning platform approaches or moves away from the guiding mold 411.

[0074] Thus, after the target mold 600 is placed on the positioning platform, the lifting drive assembly drives the positioning platform to move upward so that the positioning platform approaches the guiding mold 411 and makes the target mold 600 close to the guiding mold 411. After the base detonators in the second runner block 310 fall off, they fall into the guiding mold 411 and the target mold 600. Then, the lifting drive assembly drives the positioning platform to move downward so that the positioning platform moves away from the guiding mold 411. The guiding mold 411 can make up for the defect of the insufficient height of the target mold 600 and guide the base detonators when the base detonators fall, so that the base detonators accurately fall into the target mold 600.

[0075] Specifically, referring to Figure 8 and Figure 9 , the mounting frame 412 includes vertical plates 413 and a placing plate 414. There are two vertical plates 413. The upper ends of the two vertical plates 413 are respectively fixedly connected to the guiding mold 411 by screws. The upper ends of the two vertical plates 413 are fixedly connected to the placing plate 414 by screws. The placing plate 414 is provided with an avoidance hole 415. The avoidance hole 415 is used for the positioning platform to pass through, so as to lift the empty target mold 600 placed on the placing plate 414 and make the target mold 600 close to the guiding mold 411. After the target mold 600 is filled with base detonators, the positioning platform descends, and the filled target mold 600 is placed on the placing plate 414 for discharging.

[0076] Specifically, referring to Figure 9 the positioning platform includes a first clamping block 421, a second clamping block 422, a positioning plate 423 and a pneumatic clamping jaw 424. The pneumatic clamping jaw 424 is fixed to the lower surface of the positioning plate 423 through a fastener. There are two first clamping blocks 421. The two first clamping blocks 421 are spaced apart in the left and right direction. The two first clamping blocks 421 are respectively fixed to the two jaws of the pneumatic clamping jaw 424. There is one second clamping block 422. The second clamping block 422 is fixed to the upper surface of the positioning plate 423 through a fastener, and the second clamping block 422 is located in the front side area of the positioning plate 423. It should be noted that the positioning platform can pass through the avoidance hole 415 as a whole.

[0077] Specifically, referring to Figure 8 and Figure 9, the lifting drive assembly includes a lifting cylinder 425, fixing blocks 426 and fixing plates 427. There are two fixing blocks 426 and two fixing plates 427. The upper ends of the two fixing plates 427 are fixed to the placing plate 414 by screws. The cylinder body of the lifting cylinder 425 is located between the two fixing plates 427, and the cylinder body of the lifting cylinder 425 is fixed to the fixing plate 427 by screws. The piston rod of the lifting cylinder 425 is fixed to the lower surface of the positioning plate 423 by screws and the two fixing blocks 426. Thus, after the lifting cylinder 425 is connected to the air source and starts to work, it can drive the positioning platform to move in the up and down direction.

[0078] Thus, the lifting cylinder 425 can drive the positioning plate 423 to move upward, so as to contact the empty target mold 600 placed on the placing plate 414. During the process that the positioning plate 423 contacts the empty target mold 600, the second clamping block 422 contacts the empty target mold 600. A guiding inclined surface is provided at the upper end of the second clamping block 422, so as to cooperate with the longitudinal substrate 443 (introduced below) to realize the positioning of the target mold 600 in the front and back directions. Then, the pneumatic gripper 424 drives the two first clamping blocks 421 to approach each other, so as to realize the positioning of the target mold 600 in the left and right directions while clamping the target mold 600. Finally, the lifting cylinder 425 drives the positioning plate 423 to continue moving upward, so that the target mold 600 is closely attached to the guiding mold 411, thereby receiving the basic detonators.

[0079] Refer to Figures 10 to 13 , it should be noted that Figure 11 the cross-sectional view in Figure 10 is the cross-sectional view after being rotated 90° clockwise. In some embodiments of the present invention, the second through holes 311 are arranged in a rectangular array, the fourth through holes 416 are arranged in a rectangular array, and the horizontal spacing of the rectangular array of the second through holes 311 (refer to Figure 10 , the horizontal spacing refers to the spacing between two adjacent second through holes 311 in the left and right directions) is greater than the horizontal spacing of the rectangular array of the fourth through holes 416 (refer to Figure 10 , the horizontal spacing refers to the spacing between two adjacent fourth through holes 416 in the left and right directions). The receiving assembly 400 further includes a lateral drive assembly 430, and the lateral drive assembly 430 is used to drive the guiding mold 411 to move laterally along the horizontal direction of the rectangular array of the second through holes 311.

[0080] To increase the placement density of the base detonators in the target mold 600, the lateral spacing of the rectangular array of the fourth through-holes 416 in the guiding mold 411 needs to be correspondingly reduced. At this time, it may not be possible to transfer all the base detonators in each of the second through-holes 311 to the guiding mold 411 and the target mold 600 at once. By providing a lateral driving assembly 430 to move the guiding mold 411 and the target mold 600 together laterally along the rectangular array of the second through-holes 311, the base detonators in each of the second through-holes 311 can be transferred to the guiding mold 411 and the target mold 600 in multiple times.

[0081] Specifically, the lateral spacing of the rectangular array of the second through-holes 311 can be 1.5 times, 2 times, or other multiples of the lateral spacing of the rectangular array of the fourth through-holes 416.

[0082] Specifically, referring to Figure 12 and Figure 13 , the lateral driving assembly 430 includes a lateral driving cylinder 431, a first sliding assembly 432, and a lateral base plate 433. The cylinder block of the lateral driving cylinder 431 is fixed to the frame 500 by screws, and the piston rod of the lateral driving cylinder 431 is fixedly connected to the lateral base plate 433. The first sliding assembly 432 includes a slide rail and a slider. The slide rail is fixed to the frame 500 by screws, the slide rail and the slider are slidably connected, and the slider is fixed to the lateral base plate 433 by screws. The first sliding assembly 432 has the functions of guiding and bearing loads. The guiding mold assembly 410 is provided on the lateral base plate 433 (how to set it will be described below). Thus, after the lateral driving cylinder 431 is ventilated and operates, it can drive the guiding mold 411 and the target mold 600 to move.

[0083] Referring to Figures 10 to 13 , in a further embodiment of the present invention, the longitudinal spacing of the rectangular array of the second through-holes 311 is greater than the longitudinal spacing of the rectangular array of the fourth through-holes 416. The receiving assembly 400 further includes a longitudinal driving assembly 440, and the longitudinal driving assembly 440 is used to drive the guiding mold 411 to move longitudinally along the rectangular array of the second through-holes 311.

[0084] Similarly, to increase the placement density of the base detonators in the target mold 600, the longitudinal spacing of the rectangular array of the fourth through-holes 416 in the guiding mold 411 also needs to be correspondingly reduced. By providing a longitudinal driving assembly 440 to move the guiding mold 411 and the target mold 600 together longitudinally along the rectangular array of the second through-holes 311, the base detonators in each of the second through-holes 311 can be transferred to the guiding mold 411 and the target mold 600 in multiple times.

[0085] Specifically, referring to Figure 12 and Figure 13, the longitudinal driving assembly 440 includes a longitudinal driving cylinder 441, a second sliding assembly 442, and a longitudinal base plate 443. The cylinder block of the longitudinal driving cylinder 441 is fixed to the transverse base plate 433 by screws, and the piston rod of the longitudinal driving cylinder 441 is fixedly connected to the longitudinal base plate 443. The second sliding assembly 442 includes a guide shaft and a guide sleeve. The guide sleeve is fixed to the transverse base plate 433 by screws, the guide shaft is fixed to the longitudinal base plate 443 by screws, and the guide shaft and the guide sleeve are slidably connected. The second sliding assembly 442 functions to guide and bear the load. The placement plate 414 of the guiding die assembly 410 is fixed to the longitudinal base plate 443 by screws. Thus, after the longitudinal driving cylinder 441 is ventilated and operates, it can drive the guiding die 411 and the target die 600 to move.

[0086] Referring to Figure 6 , in a further embodiment of the present invention, multiple sets of second opening and closing assemblies 320 are provided, and each set of second opening and closing assemblies 320 is respectively used to close or open the lower orifices of a part of the second through holes 311. Thus, the second through holes 311 can be opened or closed in batches, so as to meet the requirement of discharging materials from the second runner base 310 in batches. Furthermore, when the lateral spacing of the rectangular array of the second through holes 311 is greater than the lateral spacing of the rectangular array of the fourth through holes 416, and when the longitudinal spacing of the rectangular array of the second through holes 311 is greater than the longitudinal spacing of the rectangular array of the fourth through holes 416, it is convenient for the second runner base 310 to discharge materials.

[0087] Referring to Figure 6 , in some embodiments of the present invention, each second opening and closing plate 322 is provided with a plurality of fifth through holes 323. The number of the fifth through holes 323 is less than the number of the second through holes 311, and each fifth through hole 323 of each second opening and closing plate 322 can be in one-to-one communication with the second lower orifices of a part of the second through holes 311. Thus, a single second opening and closing plate 322 can discharge the base detonators in a part of the second through holes 311 simultaneously with a smaller stroke, with high action efficiency and small occupied space.

[0088] Referring to Figure 13 and Figure 14 , in some embodiments of the present invention, the base detonator transfer die device further includes a discharging assembly 700. The discharging assembly 700 includes a discharging cylinder 710 and a pushing plate 720. The cylinder block of the discharging cylinder 710 is fixed to the frame 500, and the piston rod of the discharging cylinder 710 is fixedly connected to the pushing plate 720. After the discharging cylinder 710 is connected to the air source and starts to operate, the discharging cylinder 710 can drive the pushing plate 720 to move forward. The pushing plate 720 sequentially passes through the first through hole 434 of the transverse base plate 433 and the second through hole 444 of the longitudinal base plate 443, and pushes the target die 600 filled with base detonators out of the placement plate 414 to complete the discharging.

[0089] Combined with the above, and referring to Figures 15 to 18, for example, illustrate how the second runner base 310 with the second through-holes 311 arranged in a 5 * 10 matrix transfers 50 base detonators to the target mold 600 with storage holes 610 arranged in a 10 * 10 matrix. It should be noted that a single mold to be transferred contains 50 base detonators (refer to Figure 3 , arranged in a rhombus pattern). To fill the target mold 600 with 100 storage holes 610, it is necessary to transfer the base detonators in 2 molds to be transferred. Since the lateral spacing of the second through-holes 311 is twice the lateral spacing of the storage holes 610 (or the fourth through-holes 416, the distribution of the fourth through-holes 416 is exactly the same as that of the storage holes 610, and the storage holes 610 will be used as an example hereinafter), and the longitudinal spacing of the second through-holes 311 is twice the longitudinal spacing of the storage holes 610, the target mold 600 needs to be filled in 4 times.

[0090] First, the guiding mold 411 in the initial state fits with the right half of the second runner base 310 (refer to Figure 1 ). Under the action of the lifting drive assembly, the target mold 600 approaches the guiding mold 411 and fits with the guiding mold 411. Then, the second opening and closing plate 322 on the right moves forward, and the base detonators in 25 second through-holes 311 on the right half of the second runner base 310 are placed into the guiding mold 411 and the target mold 600. At this time, the base detonators are placed in the storage holes 610 located in the odd rows and odd columns (refer to Figure 15 ).

[0091] Next, the guiding mold 411 and the target mold 600 move to the left under the action of the lateral drive assembly 430, so that 25 storage holes 610 in the target mold 600 located in the even rows and odd columns are communicated with the corresponding second through-holes 311. The second opening and closing plate 322 on the left moves forward, and the base detonators in 25 second through-holes 311 on the left half of the second runner base 310 are placed into the guiding mold 411 and the target mold 600. At this time, the base detonators are placed in all the storage holes 610 located in the odd columns (refer to Figure 16 ).

[0092] After that, the two second opening and closing plates 322 move backward, and 50 base detonators are reloaded into the second runner base 310.

[0093] Then, the guiding mold 411 and the target mold 600 move backward under the action of the longitudinal moving assembly 440, so that 25 storage holes 610 in the target mold 600 located in the even rows and even columns are communicated with the corresponding second through-holes 311. The second opening and closing plate 322 on the right moves forward, and the base detonators in 25 second through-holes 311 on the left half of the second runner base 310 are placed into the guiding mold 411 and the target mold 600. At this time, 75 base detonators are placed in the target mold 600 (refer to Figure 17 ).

[0094] Finally, the guiding die 411 and the target die 600 are moved rightward under the action of the lateral driving assembly 430, so that 25 storage holes 610 located in the odd rows and even columns of the target die 600 communicate with the corresponding second through holes 311, filling the last 25 storage holes 610, thereby completing the filling of the target die 600.

[0095] The die transfer machine according to the second aspect embodiment of the present invention includes the above-mentioned basic detonator die transfer device. By using the above-mentioned basic detonator die transfer device, the firing probability of the basic detonator can be reduced, and the safety factor of the die transfer machine can be improved.

However, the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
