[0034] The following is combined with Figures 1 to 9 The present invention is further described in detail, but is not intended to limit the present invention.

[0035] like Figure 1 and 2As shown, in one embodiment of the present invention, the cable forming equipment comprises a protective shell 100 and an inner mold body 200, a middle mold body 300 and an outer mold body 400 which are sequentially arranged inside the protective shell 100; a forming path which can respectively penetrate the inner mold body 200, the middle mold body 300 and the outer mold body 400 is provided in the protective shell 100; and the forming path is also used to convey the metal conductor of the cable; a first feeding channel 101 and a second feeding channel 102 are also provided on the protective shell 100; a first casting gap 601 is provided between the inner mold body 200 and the middle mold body 300; and the first casting gap 601 is connected to the forming path; a second casting gap 602 is provided between the middle mold body 300 and the outer mold body 400; and the second casting gap 602 is connected to the forming path.

[0036] The technical solution of the present invention adopts a three-layer sealed molding setting of an inner mold, a middle mold body and an outer mold body to form a second casting gap and a first casting gap, thereby realizing the molding processing of the inner casting layer and the outer casting layer of the cable, thereby ensuring the orderliness of the molding, improving the operational stability and efficiency, and reducing the defective rate of the cable.

[0037] Wherein, in some embodiments, Figure 1 As shown, the first feeding channel 101 is arranged above the second feeding channel 102. The two protective materials are transported by pouring at the upper and lower sides to achieve staggered pouring and avoid mutual interference and other influences.

[0038] Specifically, in some embodiments, Figure 1 and 2 As shown, the middle mold body 300 is provided with a first conveying channel 301 and a second conveying channel 302; the input port of the first conveying channel 301 is connected to the first feeding channel 101; the output port of the first conveying channel 301 is connected to the first casting gap 601; the input port of the second conveying channel 302 is connected to the second feeding channel 102; the output port of the second conveying channel 302 is connected to the second casting gap 602; and the first conveying channel 301 is not connected to the second casting gap 602; the second conveying channel 302 is not connected to the first casting gap 601. Figure 1 , 2 As shown in FIG. 6 , the first conveying channel 301 includes a first through hole 3011 and a second through hole 3012 vertically arranged; the first through hole 3011 is extended along the height direction of the middle mold body 300 and communicates with the first feeding channel 101; the second through hole 3012 is extended along the thickness direction of the middle mold body 300 and communicates with the first casting gap 601. Figure 1 , 2As shown in Figure 6, the second conveying channel 302 includes a third through hole 3021 and a fourth through hole 3022 arranged vertically; the third through hole 3021 is extended along the height direction of the middle mold body 300 and communicates with the second feeding channel 102; the fourth through hole 3022 is extended along the thickness direction of the middle mold body 300 and communicates with the second casting gap 602. This structure can realize the feeding and conveying of a single component and different materials by performing the feeding of two (same or different) casting materials at the upper and lower ends of the middle mold body 300, which is conducive to the convenience of subsequent maintenance and repair operations of the feeding process and reduces the detection of multiple groups of components. In addition, the material feeding on the front and rear sides is realized through the middle mold body 300 to ensure the smoothness of molding in different processes.

[0039] Specifically, in some embodiments, Figure 1 and 2 As shown, the protective shell 100 includes a partition component 110, a main shell 120 and a locking component 130; the partition component 110 and the locking component 130 are respectively connected to the inner ends of the main shell 120; and the inner mold body 200, the middle mold body 300 and the outer mold body 400 are arranged between the partition component 110 and the locking component 130;

[0040] In addition, a first conveying cavity 111 is provided in the partition component 110; a second conveying cavity 121 is provided in the main housing 120; a fifth conveying cavity 131 is provided in the locking component 130; a third conveying cavity 401 is provided in the outer mold body 400; the first conveying cavity 111, the second conveying cavity 121, the third conveying cavity 401 and the fifth conveying cavity 131 are connected to each other along the direction of the molding path. Further, the partition component 110 is detachably connected to the inside of the main housing 120 through a fixing nut; the locking component 130 is detachably connected to the inside of the main housing 120 through a fixing thread. This structure realizes the limiting effect of the upper, lower, left and right positions of the inner mold body 200, the middle mold body 300 and the outer mold body 400 through the partition component 110, the main housing 120 and the locking component 130, so as to ensure the stable molding process.

[0041] Specifically, in some embodiments, Figure 1 , 3As shown in Figure 5, at least one conductor delivery channel 202 is provided on one side end of the inner mold body 200 facing the first casting gap 601; the conductor delivery channel 202 penetrates the thickness of the inner mold body 200; and the inner diameter of the conductor delivery channel 202 is larger than the outer diameter of the cable metal conductor delivered by the molding path; the input port of the conductor delivery channel 202 is connected to the vacuum pressure pipe; at least one first inflation channel 203 is provided on one side end of the inner mold body 200 facing the first casting gap 601; the first inflation channel 203 penetrates the thickness of the inner mold body 200; and a blowing component 210 is provided at the input port of each first inflation channel 203. Among them, the number of first inflation channels 203 is twelve, and they are symmetrically arranged inside the inner mold body 200. Among them, as Figure 1 and 5 As shown, the air extraction pressure pipe is used to communicate with the extraction and compression machine; the input port of the air extraction pressure pipe is arranged between the outer wall of the cable metal conductor and the inner wall of the conductor conveying channel 202. Figure 5 As shown, the number of the conductor delivery channels 202 is two, and they are symmetrically arranged inside the inner mold body 200. Further, as Figure 3 and 4 As shown, the blowing assembly 210 includes a blowing forming tube 211; a charging hole 212 is provided in the blowing forming tube 211; and the charging hole 212 is connected to the input port of the first charging channel 203. That is to say, when the first material is fed from the first feeding channel 101 to the first casting gap 601, 12 air holes are formed in the initial structure of the cable through the continuous blowing action of the blowing forming tube 211 and the continuous conveying action of the cable metal conductor; and the first material can be more closely attached to the cable metal conductor under the suction action of the conductor conveying channel 202, thereby improving the production and processing quality and efficiency through the action of blowing and sucking.

[0042] Specifically, in some embodiments, Figure 2 and 3As shown, a mounting protrusion 2012 is provided in the surface of one side of the inner mold body 200 away from the middle mold body 300; a guide arc section 2011 is provided between the top of the mounting protrusion 2012 and the inner top of the inner mold body 200; a collecting recess section 2013 is provided between the bottom of the mounting protrusion 2012 and the inner bottom of the inner mold body 200. The guiding arc section 2011 is a semicircular guiding arc; the collecting recess section 2013 is a recess with a W-shaped or inverted Ω-shaped cross section. Since part of the first material will pass through the conductor conveying channel 202 under the action of vacuum and pressure extraction, the W-shaped or inverted Ω-shaped recess is used to collect part of the material, so as to avoid blocking the conductor conveying channel 202 under the action of vacuum and pressure extraction, thereby ensuring the smoothness of production and processing. In addition, through the suction and air extraction action of the upper guide arc segment 2011, the two sides of the bottom of the guide arc segment 2011 can be subjected to negative pressure, so that the excess first material can be blown up onto the metal conductor of the cable, thereby avoiding adhesion and blockage caused by excessive collection, thereby ensuring the smoothness of production and processing.

[0043] Specifically, in some embodiments, Figure 1 , 2 As shown in FIG. 6 , a forming mold 310 is disposed in the middle mold body 300; the forming path is disposed through the forming mold 310; and the forming mold 310 is extended toward the direction of the outer mold body 400.

Figure 7 As shown, the cross section of the molding cavity 303 is a symmetrical cavity of the shape of an 8. The structure transports the cable metal conductor with the first material and multiple pores through the interior of the molding die 310 to form a preliminary casting body with a depression in the middle and at least one groove around the upper and lower ends; to achieve the first process of partial processing of the cable structure; and finally, through the reinforcement casting of the second casting gap 602, a special cable structure (such as Fig. 9 shown).

[0044] Specifically, in some embodiments, Figure 1 , 2As shown in FIG. 8 , a gas delivery component 500 is further provided inside the protective shell 100; the gas delivery component 500 is disposed on a side of the inner mold body 200 away from the middle mold body 300; and the gas delivery component 500 is connected to the blowing assembly 210 and the conductor delivery channel 202.
