Description

Technical Field

[0001] This utility model relates to the field of casting mold technology, and in particular to a multi-station cable clamp casting mold. Background Technology

[0002] A cable clamp is a device used to secure cables. It can fix the cables in a proper position and prevent them from moving or being damaged. Some types of cable clamps need to be produced using a casting process, which requires the use of casting molds.

[0003] A casting mold generally includes an upper mold and a lower mold. After the upper mold and the lower mold are fitted together, the molten metal material is added through the feed port set inside the upper mold. Then, the molten material added into the mold is cooled by the cooling system inside the mold, thereby realizing the casting production of the fixed frame.

[0004] Therefore, existing casting molds generally consist of two parts: an upper mold and a lower mold. Since the cable fixing bracket is U-shaped and the outer surface of the cable fixing clamp has many reinforcing ribs and reserved holes to strengthen the structure, it needs to be cast vertically. This means that existing molds can only cast one fixing clamp at a time, and most of the interior of the mold is solid, such as the middle part of the U-shaped fixing clamp, which is not well utilized, resulting in wasted space and reduced casting efficiency.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present invention. This embodiment provides a multi-station cable clamp casting mold, including a base 2, a mold assembly 1 on the upper surface of the base 2, and an ejection assembly 3 inside the base 2. The mold assembly 1 includes a lower mold 104 fixedly connected to the upper surface of the base 2, a middle mold 103 on the upper surface of the lower mold 104, an upper mold 102 above the middle mold 103, a plurality of first feed ports 101 inside the upper mold 102, a second feed port 105 inside the middle mold 103, the second feed port 105 being inserted into the first feed ports 101, a plurality of plug-in blocks 106 on the outer surface of the middle mold 103, and a guide port 107 connected to the second feed port 105 inside the plug-in blocks 106 on the lower surface of the middle mold 103. The upper mold 102, the middle mold 103, and the lower mold 104 are all provided with mold grooves for casting.

[0030] Specifically, four limiting shafts 4 are fixedly connected to the upper surface of the base 2. The limiting shafts 4 are inserted into the lower mold 104, the middle mold 103 and the upper mold 102. A gap is left between the first feed port 101 and the second feed port 105 for feeding material into the mold groove inside the upper mold 102. The middle mold 103 and the lower mold 104 are provided with round holes for lifting rod 302 to rise and fall. The diameter of the plug block 106 is the same as the diameter of the through hole reserved inside the cable fixing clamp. The diameter of the plug block 106 is smaller than the diameter of the first feed port 101.

[0031] Furthermore, material is fed into the first feed port 101 inside the upper mold 102 and the second feed port 105 intersecting inside the first feed port 101. The gap between the first feed port 101 and the second feed port 105 guides material into the mold groove inside the upper mold 102 and the mold groove inside the middle mold 103 that connects with the upper mold 102. Material entering the second feed port 105 then enters the mold groove inside the lower mold 104 through the bottom guide port 107. After filling the mold groove inside the lower mold 104, the material... The material rises to the mold groove inside the middle mold 103 and connects with the lower mold 104, ultimately filling the interior of the upper mold 102, middle mold 103, and lower mold 104. The mold groove inside the upper mold 102 and the mold groove inside the lower mold 104 are symmetrically staggered. The positions of the pre-reserved holes for fixing clamps inside the insert block 106, the mold groove inside the upper mold 102, and the mold groove inside the lower mold 104 are kept coaxial, thereby realizing the utilization of the space inside the U-shaped fixing frame during casting. The pre-reserved holes for casting are realized through the insert block 106.

[0032] Example 2

[0033] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 This is the second embodiment of the present invention. Based on the previous embodiment, the ejector assembly 3 includes two first springs 306 fixedly connected to the lower surface of the lower mold 104. The bottom end of the first spring 306 is fixedly connected to a lifting plate 303. A lifting rod 302 is inserted inside the lifting plate 303. The top end of the lifting rod 302 passes through the lower mold 104 and the middle mold 103 and is fixedly connected to the lower surface of the upper mold 102. A first ejector pin 305 is fixedly connected to the upper surface of the lifting plate 303. A second spring 309 is fixedly connected to the lower surface of the lower mold 104. The bottom end of the second spring 309 is fixedly connected to an abutment plate 308. A second ejector pin 307 is fixedly connected to the upper surface of the abutment plate 308. A connecting rod 301 is fixedly connected to the upper surface of the middle mold 103. The top end of the connecting rod 301 passes through the upper mold 102 and is fixedly connected to a locking block 304. The bottom end of the lifting rod 302 passes through the lifting plate 303 and is fixedly connected to the same locking block 304.

[0034] Specifically, the bottom of the circular hole inside the lower mold 104 is connected to a circular groove. The top of the first spring 306 is fixedly connected to the inner wall of the circular groove. When the first spring 306 and the second spring 309 are reset, they can drive the tops of the first ejector pin 305 and the second ejector pin 307 to fit against the inner wall of the mold groove.

[0035] Furthermore, the upper mold 102 is pulled up, opening the gap between the upper mold 102 and the middle mold 103, and causing the second feed port 105 to separate from the first feed port 101. The upper mold 102 continues to move the lifting rod 302 upward, causing the locking block 304 at the bottom of the lifting rod 302 to abut against the lower surface of the lifting plate 303. Thus, as the upper mold 102 continues to be pulled up, the lifting rod 302 rises, causing the first ejector pin 305 on the upper surface of the lifting plate 303 to eject the cast workpiece between the upper mold 102 and the middle mold 103. The upper mold 102 continues to move until the upper surface of the upper mold 102 abuts against the first ejector pin 305 on the upper surface of the lifting plate 303. The locking block 304 at the top of the connecting rod 301 causes the upper mold 102 to move together with the middle mold 103 via the connecting rod 301 and the locking block 304 at the top of the connecting rod 301, thus opening the gap between the middle mold 103 and the lower mold 104. The upper mold 102 continues to move until the upper surface of the lifting plate 303 abuts against the lower surface of the abutment plate 308. At this time, the gap between the middle mold 103 and the lower mold 104 has been opened. Then the upper mold 102 continues to rise, thereby driving the second ejector pin 307 to push the cast workpiece between the middle mold 103 and the lower mold 104 upward through the abutment plate 308.

[0036] Working principle: During the casting production of cable clamps, the upper mold 102, middle mold 103, and lower mold 104 are sequentially connected by the limiting shaft 4. The upper mold 102 compresses the upper mold 102, middle mold 103, and lower mold 104 to fit tightly together. Then, material is fed into the first feed port 101 inside the upper mold 102 and the second feed port 105 inserted inside the first feed port 101. The gap between the first feed port 101 and the second feed port 105 allows material to be poured into the mold groove inside the upper mold 102 and the mold groove inside the middle mold 103 that connects with the upper mold 102. The material enters the second feed port 105. The material enters the mold groove inside the lower mold 104 through the bottom guide port 107. After filling the mold groove inside the lower mold 104, the material rises to the mold groove inside the middle mold 103 that connects with the lower mold 104. Finally, the material fills the interior of the upper mold 102, middle mold 103, and lower mold 104. The pre-drilled hole inside the cable fixing clamp is realized through the plug-in block 106 set on the outer surface of the middle mold 103. After the material inside has cooled down, the upper mold 102 is pulled up, opening the gap between the upper mold 102 and the middle mold 103. The upper mold 102 drives the lifting rod 302 to move upward, so that the locking block 304 at the bottom of the lifting rod 302 and the lower part of the lifting plate 303 are engaged. The surfaces come into contact, and as the upper mold 102 continues to open, it causes the lifting rod 302 to rise, thereby causing the first ejector pin 305 on the upper surface of the lifting plate 303 to eject the cast workpiece between the upper mold 102 and the middle mold 103. The upper mold 102 continues to move until its upper surface abuts against the locking block 304 at the top of the connecting rod 301, causing the upper mold 102 to move together with the middle mold 103 through the connecting rod 301 and the locking block 304 at the top of the connecting rod 301, thus opening the gap between the middle mold 103 and the lower mold 104. The upper mold 102 continues to move until the upper surface of the lifting plate 303 abuts against the abutment plate 3. On the lower surface of 08, the gap between the middle mold 103 and the lower mold 104 has been opened. Then the upper mold 102 continues to rise, thereby driving the second ejector pin 307 to push the workpiece cast between the middle mold 103 and the lower mold 104 upward through the abutment plate 308, and finally completing the casting of the cable clamp. Through the setting of the upper mold 102, the middle mold 103 and the lower mold 104, multiple clamps can be cast at the same time, thereby improving the space utilization rate inside the mold and improving the casting efficiency. As the upper mold 102 is pulled up, the workpieces between the upper mold 102 and the middle mold 103 and between the middle mold 103 and the lower mold 104 are ejected respectively, which is convenient for material removal.
