Description

Technical Field

[0001] The utility model relates to the technical field of die casting moulds, in particular to a die casting mould structure without a soup mouth sleeve. Background Art

[0002] like Figure 1-Figure 4 As shown, the existing sleeve die-casting mold structure includes a sleeve 1, a mother template 2, a blowout plate 3 and a diverter cone 4. The blowout plate and the sleeve are inlaid on the inner and outer sides of the mother template respectively. The center hole of the blowout plate is connected to the sleeve. The sleeve is connected to the material pipe, and the material pipe is connected to the diverter cone through the sleeve. Due to the sleeve connecting to the material pipe, the high-frequency injection action of the material pipe output and the impact of the aluminum liquid on the sleeve, after 30,000 to 50,000 times of use, the sleeve will be cracked, the inner wall is worn, and the clearance between the punch of the material pipe increases and it cannot be used. A new sleeve needs to be made and replaced, which is expensive. In addition, due to the structural limitations of the sleeve, the matching area with the sealing surface of the diverter cone is small, and the problem of downward spraying is prone to affect production. At the same time, the layout space of the cooling water channel on the sleeve is relatively small, which is not easy to process and has frequent cracking and leakage problems. Utility Model Content

[0003] In order to solve the above technical problems, the utility model designs a die-casting mold structure without a soup mouth sleeve.

[0004] The utility model adopts the following technical solutions:

[0005] A die-casting mold structure without a soup sleeve comprises a mother template, an integrated blowout preventer, a diverter cone and a material pipe, wherein a blowout preventer installation groove and a material pipe docking interface are correspondingly arranged on inner and outer sides of the mother template, an integrated blowout preventer is installed in the blowout preventer installation groove, a diverter cone is connected in a center hole of the integrated blowout preventer, a material pipe is installed in the material pipe docking interface, an end of the material pipe passes through the material pipe docking interface and is tightly attached to the integrated blowout preventer, and an inner hole of a punch of the material pipe is directly docked with the diverter cone.

[0006] Preferably, a cooling water channel is provided on the integrated blowout prevention plate.

[0007] Preferably, the material pipe is plugged into the material pipe docking port.

[0008] Preferably, the inner diameter of the center hole of the integrated blowout preventer is 3-5 mm larger than the inner diameter of the punch.

[0009] The beneficial effects of the utility model are as follows: the utility model changes the original two-piece structure of the soup mouth sleeve and the blowout prevention plate into an integrated blowout prevention plate combined structure, and the blowout prevention plate cooperates with the diverter to realize the function of the soup mouth sleeve; the soup mouth sleeve-free integrated blowout prevention plate structure is adopted, and the soup mouth sleeve does not need to be replaced during the life of the mold, which saves mold costs and is simple to make, reduces the mold abnormality rate, and solves the problems of short life of the soup mouth sleeve of the traditional structure, high spare parts cost, punch jamming, soup mouth sleeve leakage, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0020] Example: Figure 5-Figure 8 As shown, a die-casting mold structure without a soup sleeve includes a mother template 2, an integrated blowout preventer 6, a diverter cone 4 and a material pipe 5. The blowout preventer installation groove and the material pipe docking interface are correspondingly arranged on the inner and outer sides of the mother template. The integrated blowout preventer is installed in the blowout preventer installation groove. The diverter cone is connected in the center hole of the integrated blowout preventer. The material pipe is installed in the material pipe docking interface. The end of the material pipe passes through the material pipe docking interface and is tightly attached to the integrated blowout preventer. The inner hole of the punch of the material pipe is directly opposite to the corresponding diverter cone.

[0021] The integrated anti-spray plate is provided with a cooling water channel 7. The material pipe and the material pipe docking interface are plugged in cooperation.

[0022] The inner diameter of the center hole of the integrated blowout preventer is 3-5mm larger than the inner diameter of the punch.

[0023] The utility model changes the original two-piece structure of the soup mouth sleeve and the anti-blowout plate into an integrated anti-blowout plate combined structure. The anti-blowout plate cooperates with the diverter to realize the function of the soup mouth sleeve. The integrated anti-blowout plate structure without the soup mouth sleeve is adopted. There is no need to replace the soup mouth sleeve during the life of the mold, which saves mold cost and is simple to make, reduces the mold abnormality rate, and solves the problems of short life of the soup mouth sleeve of the traditional structure, high spare parts cost, punch jamming, soup mouth sleeve leakage, etc.

[0024] The above-described embodiment is only a preferred solution of the present invention and does not limit the present invention in any form. There are other variations and modifications without exceeding the technical solution described in the claims.
