Description

Technical Field

[0001] This utility model belongs to the technical field of pressure casting equipment, specifically relating to a ring seat and spring punch with a multi-oil-circuit structure. Background Technology

[0002] Pressure casting is a casting method in which liquid or semi-solid metal or alloy, or liquid metal or alloy containing reinforcing phases, is filled into the cavity of a die-casting mold at high pressure and high speed, and the metal or alloy is solidified under pressure to form a casting.

[0003] The injection punch is a key component of a pressure casting machine. During the pressure casting process, it is primarily used to inject molten metal into the mold cavity. The performance of the injection punch directly affects the product quality. In existing technologies, the reciprocating motion of the injection punch, coupled with repeated friction against the molten cup and the injection chamber walls, easily leads to severe wear. This results in poor sealing and further prevents the vacuum effect within the mold cavity from reaching a stable state, causing the obtained products to fail to meet quality requirements. This is especially problematic in high-vacuum pressure casting environments, where it significantly reduces the product yield.

[0004] While conducting early research on the problem of friction and wear between the punch, molten cup, and injection chamber wall, the applicant filed patent application CN202022672005.2, which discloses a spring-supported ring punch. By using a steel ring and a copper ring installed on the punch, under the action of the inner support spring, the frictional loss between the copper ring and the molten cup can be stably compensated, so that the copper ring and the inner wall of the injection chamber are always in close contact. The high sealing state achieved by this compensation method can stably reduce the vacuum value and greatly improve product quality.

[0005] Meanwhile, a lubricating oil channel connected to the connector and the injection rod is provided inside the punch. During the reciprocating motion of the punch, lubricating oil is sprayed out to lubricate the inner and outer walls of the above-mentioned components, thereby extending the service life of the injection chamber and the punch.

[0006] Further research by the applicant revealed the following shortcomings in the actual use of the punch in this technical solution: After the molten aluminum is poured into the barrel, the impact force of the molten aluminum on the punch is relatively large at the bottom horizontal surface of the punch, and the outer wall at the bottom horizontal surface of the punch is most susceptible to erosion, which will adversely affect the service life of the ring seat. The only way to ensure the quality of the casting is to replace the ring seat. Utility Model Content

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A ring seat with a multi-oil-channel structure includes:

[0009] The ring seat body has a closed first end face and an open second end face;

[0010] The oil injection channel is formed inside the peripheral wall of the ring seat body and extends axially towards the second end face along the ring seat body body.

[0011] An oil drain port is provided on the outer wall of the ring seat body and is connected to the oil injection channel;

[0012] A positioning hole is formed on the second end face and extends axially toward the first end face along the ring seat body;

[0013] The oil injection channel is provided in at least two sets, and the oil injection channel and the positioning hole are staggered.

[0014] Furthermore, the oil injection channels and positioning holes are evenly distributed around the second end face.

[0015] Furthermore, a sealing ring is provided at the end of the oil injection channel.

[0016] Furthermore, the ring seat body has a spiral liquid guiding groove, which is formed on the inner side of the first end face.

[0018] Furthermore, the outer periphery of the ring seat body is provided with one or more of the following: a head ring, a copper ring, an oil injection ring, and a tail ring.

[0019] Furthermore, an annular groove is provided on the ring seat body, and the head ring, copper ring, oil injection ring and tail ring are respectively installed in the annular groove.

[0020] Compared with the prior art, this utility model has the following advantages:

[0021] This design employs multiple pre-set oil injection channels within the ring seat body, which can connect to the connector and / or injection rod. When the bottom of the ring seat may be eroded, the entire ring seat and punch are rotated using a tool, connecting another pre-set oil injection channel to the existing oil passages of the connector and / or injection rod.

[0029] like Figure 1 - Figure 3 As shown, the present invention provides a ring seat with a multi-oil-channel structure, comprising:

[0030] The ring seat body 1 has a closed first end face 10 and an open second end face 11;

[0031] The oil injection channel 2 is opened in the peripheral wall of the ring seat body 1 and extends along the axial direction of the ring seat body 1 toward the second end face 11.

[0032] Oil drain port 21 is provided on the outer wall of the ring seat body 1 and is connected to the oil injection channel 2;

[0033] The positioning hole 3 is opened on the second end face 11 and extends along the axis of the ring seat body 1 toward the first end face 10;

[0034] The oil injection channel 2 has at least two sets, and the oil injection channel 2 and the positioning hole 3 are staggered.

[0035] Multiple sets of oil injection channels 2 are pre-set in the ring seat body 1, which can be connected to the connector 8 and / or the injection rod. When the bottom of the ring seat may be in an erosion state, the ring seat and the punch as a whole are rotated using a tool, so that another set of pre-set oil injection channels 2 are connected to the oil passages of the original connector 8 and / or the injection rod. With this structure, the ring seat can be rotated multiple times without frequent replacement, and the ring seat can be reused multiple times, avoiding unnecessary waste. A locating pin can be inserted into the locating hole 3 to connect the connector 8 and the ring seat, aligning their oil passages.

[0036] The rotation angle of the ring seat and the spring punch is related to the number of oil injection channels. In this embodiment, there are 6 sets of oil injection channels.

[0037] A connector 80 is provided between the ring seat body 1 and the connector 8, and a sealing element is fitted on the outer periphery.

[0038] Multiple pin holes 81 that match the positioning holes are provided on the connector 8, and the two are connected by pins.

[0039] Specifically, the aforementioned oil injection channels 2 and positioning holes 3 are evenly distributed around the second end face 11.

[0040] In addition, a sealing ring 20 is provided at the end of the oil injection channel 2.

[0041] This embodiment also discloses a spring punch having the aforementioned ring seat body 1.

[0042] In this embodiment, a spiral liquid guiding groove 100 is provided in the ring seat body 1, and the spiral liquid guiding groove 100 is opened on the inner side of the first end face 10.

The liquid guide tube 9 carries the cooling medium, such as water, in a spiral shape through the first end face 10 under the action of the spiral liquid guide groove 100, increasing the contact area between the ring seat and the cooling medium, thereby achieving a better heat dissipation effect.

[0044] like Figure 3As shown, the outer circumference of the ring seat body 1 is provided with one or more of the following: a head ring 4 with a break line, a copper ring 5, an oil injection ring 6, and a tail ring 7.

[0045] The ring seat body 1 has an annular groove 12, and the first ring 4, copper ring 5, oil injection ring 6 and tail ring 7 are installed in the annular groove 12.

[0046] The oil injection ring 6 can communicate with the oil injection hole 82 of the connector 8 and / or the injection rod to guide the lubricating oil to the metal rings on the outer periphery of the ring seat body 1.

[0047] Specifically, in this embodiment, the first and last rings are made of steel alloy. Their connection to the copper ring and the installation method are existing technologies. For specific structures and connection methods, please refer to the technical solutions mentioned in patent documents CN202022672005.2 and CN201720756503.0. The aforementioned structures are not within the scope of protection of this application.

[0048] This metal ring arrangement can stably compensate for frictional losses between the punch and the molten cup, ensuring that the first ring and / or other metal rings are always in close contact with the inner wall of the injection chamber, greatly improving product quality.
