Description

Technical Field

[0001] This utility model relates to the field of mold application technology, and in particular to a die casting mold gating sleeve insert assembly with 3D printed sealing conformal water channel. Background Technology

[0002] The basic working process of die casting is as follows: First, liquid or semi-liquid metal is poured into the pressure chamber of the die casting machine by casting. Then, the injection mechanism of the die casting machine applies high pressure, causing the molten metal to fill the mold cavity at an extremely high speed and solidify under pressure, thereby obtaining the die casting.

[0003] Existing die-casting molds are subject to damage at the gate due to the interaction of high and low temperatures during casting, which reduces the service life of the die-casting mold gate sleeve and increases the manufacturing cost of the die-casting mold gate sleeve. Therefore, this utility model proposes a die-casting mold gate sleeve insert assembly with 3D printed sealing conformal water channels. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a die-casting mold gate sleeve insert assembly with 3D printed sealing conformal water channels. By using 3D printing technology to seal the conformal water channels inside the die-casting mold, leakage can be prevented when coolant enters the pipes and flows inside. At the same time, the 3D printed material can provide a certain degree of protection against the low temperature and low pressure generated around the cooling pipes inside the insert body during casting, thereby extending the service life of the insert body.

[0005] To solve the above technical problems, the present invention adopts a technical solution as follows: a die casting mold gate sleeve insert assembly with 3D printed sealing conformal water channels is provided, including an insert body, side blocks are symmetrically engaged on both sides of the insert body, and conformal cooling pipes are opened on the top of the insert body near the inner wall.

[0006] A plugging ring is engaged with the top of the inlay body at the corresponding position of the cooling pipe. A cover plate is 3D printed on the top of the plugging ring to protect the central gate of the inlay body and seal the contact point between the plugging ring and the cooling pipe.

[0007] The present invention is further configured such that: the two sides of the inlay body are symmetrically provided with card blocks, and the opposite surfaces of the two side blocks are provided with card slots, and are connected to the card blocks by the card slots.

[0008] The above technical solution facilitates quick installation on both sides of the inlay body using the slots inside the side blocks, thereby enabling handling operations.

[0009] The present invention is further configured such that: a flow guide groove is provided at the bottom front wall of the inlay body, and the flow guide groove is connected to the central gate of the inlay body.

[0010] The above technical solution facilitates the use of the set guide channel to guide the poured liquid or semi-liquid, thereby facilitating the subsequent die-casting operation.

[0011] The present invention is further configured such that: an embedding groove is provided at the top of the cooling pipe, and the plugging ring is engaged with the embedding groove and provides a sealing solution for the top of the cooling pipe.

[0012] The above technical solution facilitates the pre-sealing of cooling pipes with plugging rings, preventing coolant leakage during use.

[0013] The present invention is further configured such that: a printing area is provided on the top of the inlay body, the cover plate is installed in the printing area, and the connection between the plugging ring block and the cooling pipe is sealed.

[0014] The above technical solution facilitates the printing of suitable cover plates in the printing area according to requirements, further sealing the cooling pipes and making it easy to replace later, thus reducing costs.

[0015] The present invention is further configured such that positioning holes are provided at the corners of both side blocks.

[0016] The above technical solution allows the positioning holes on both sides to fix the position of the entire component, facilitating subsequent casting operations.

[0017] The present invention is further configured such that: the front wall of the inlay body is symmetrically provided with liquid inlet holes and liquid outlet holes near the middle position, and the liquid inlet holes and liquid outlet holes are respectively connected to the two ends of the annular cooling pipe.

[0018] The above technical solution facilitates the injection of external cooling medium into the internal cooling pipes through the inlet and outlet holes, enabling circulation and thus cooling the mold gate.

[0019] The beneficial effects of this utility model are as follows:

[0020] This invention proposes a die-casting mold gating sleeve insert assembly with 3D-printed sealing conformal water channels. By using 3D printing technology to seal the conformal water channels inside the die-casting mold, leakage can be prevented when coolant enters and flows into the pipes. At the same time, the 3D-printed material can provide some protection against the low temperature and low pressure generated around the cooling pipes inside the insert body during casting, thereby extending the service life of the insert body.

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0028] like Figure 2 and Figure 3 As shown, a die-casting mold gate insert assembly with 3D-printed sealing conformal water channels includes an insert body 1. A guide groove 12 is provided on the bottom front wall of the insert body 1, and the guide groove 12 is connected to the central gate of the insert body 1. This facilitates the guidance of poured liquid or semi-liquid through the guide groove 12, thereby facilitating subsequent die-casting operations. Side blocks 2 are symmetrically engaged on both sides of the insert body 1. Positioning holes 22 are provided at the corners of both side blocks 2. The positioning holes 22 on both sides can fix the position of the entire assembly, facilitating subsequent casting operations. Clamping blocks 11 are symmetrically arranged on both sides of the insert body 1. The opposite surfaces of the two side blocks 2 are provided with clamping grooves 21, and they are engaged with the clamping blocks 11 through the clamping grooves 21. This allows for quick installation on both sides of the insert body 1 using the clamping grooves 21 inside the side blocks 2, thereby facilitating handling operations.

[0029] like Figures 1-5As shown, a conformal cooling pipe 3 is provided on the top of the inlay body 1 near the inner wall. A liquid inlet 31 and a liquid outlet 32 ​​are symmetrically provided on the front wall of the inlay body 1 near the middle. The liquid inlet 31 and the liquid outlet 32 ​​are respectively connected to the two ends of the annular cooling pipe 3, facilitating the injection of external cooling medium into the internal cooling pipe 3 through the liquid inlet 31 and the liquid outlet 32 ​​for circulation, thereby cooling the mold gate. A plugging ring block 4 is engaged with the top of the inlay body 1 at the corresponding position of the cooling pipe 3. An embedding groove 13 is provided on the top of the cooling pipe 3, and the plugging ring block 4 is engaged with the embedding groove 13, sealing the top of the cooling pipe 3. This allows for pre-sealing of the cooling pipe 3 using the plugging ring block 4, preventing coolant leakage during use. The top of the plugging ring block 4... The part is equipped with a cover plate 5 by 3D printing to protect the central gate of the inlay body 1 and seal the contact between the plugging ring block 4 and the cooling pipe 3. The top of the inlay body 1 has a printing area 14, which makes it easy to print a suitable cover plate 5 according to the needs of the printing area 14, so as to further seal the cooling pipe 3, and facilitate replacement later, reducing the cost investment. The printing area 14 is located at the cooling pipe 3, so low temperature and low pressure will occur here during casting. The cover plate 5 is installed in the printing area 14 and is set to seal the connection between the plugging ring block 4 and the cooling pipe 3. The resulting hot and cold changes will affect the cover plate 5 and cause damage to the cover plate 5, reducing damage to the inlay body 1. Since the cost of 3D printing materials is low, it can be replaced at any time, thereby extending the service life of the inlay body 1.

[0030] In use, the two side blocks 2 are first engaged with the two sides of the inlay body 1 using their slots 21. Then, the blocking ring block 4 is installed inside the embedding groove 13 opened at the top of the cooling pipe 3 for pre-sealing. Finally, suitable materials are printed and fixed in the printing area 14 using 3D printing technology, thereby further sealing and fixing the cooling pipe 3. At the same time, it bears most of the damage caused to the inlay body 1 during casting, thus extending the service life of the inlay body 1.
