When replacing the base plate, the first bolt can be matched with the first thread groove, and the first bolt and the connecting rod are released from the locked state. However, the first bolt needs to be turned out of the first thread groove when disassembling, and cooling grooves are provided on both sides of the auxiliary block, which makes the operating space small. When the first bolt is turned, it is easy to collide with the cooling groove, which is inconvenient to operate.

[0005] In order to solve the above problems, the utility model proposes a die-casting mold pouring structure. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 4 As shown, the technical solution adopted by the utility model is as follows: a die-casting mold pouring structure, including a working box 1, and a water storage tank 6 is vertically slidably arranged inside the working box 1. An electric push rod 5 is fixedly connected to the bottom surface of the inner cavity of the working box 1, and the telescopic rod at the output end of the electric push rod 5 is fixedly connected to the bottom surface of the water storage tank 6.

[0025] The top of the working box 1 is fixedly connected with a fixed mold 3, and the fixed mold 3 cooperates with the movable mold 9 for easy casting. The top of the fixed mold 3 is fixedly provided with a gate 4, which is connected to the injection cavity inside the fixed mold 3. The liquid material is passed into the injection cavity through the gate 4.

[0026] The top of the water storage tank 6 is horizontally slidably provided with a movable mold 9. A plurality of limit blocks 11 are slidably provided on the water storage tank 6. A plurality of limit grooves are provided at the bottom of the movable mold 9. The limit blocks 11 are clamped in the corresponding limit grooves. The cross-sectional shape of the top of the limit block 11 is triangular. The top of the limit block 11 has two inclined surfaces, which are distributed along the sliding direction of the movable mold 9, so that the movable mold 9 can squeeze the limit block 11 through the inclined surfaces.

[0027] Both ends of the bottom surface of the movable mold 9 are fixedly connected with a slide plate 14, and the limit groove is provided on the slide plate 14. Two slide grooves are provided on the top surface of the water storage tank 6, and the slide plates 14 are slidably arranged in the corresponding slide grooves.

[0028] Two symmetrical slots 12 are provided on the bottom surface of each slide slot, and the slots 12 are arranged vertically. Limiting blocks 11 are slidably arranged in the corresponding slots 12, and springs 10 are fixedly connected between the bottom surface of the slots 12 and the corresponding limiting blocks 11.

[0029] The water storage tank 6 is provided with a water inlet and a drain outlet. Cold water is introduced into the water storage tank 6 through the water inlet, and water is discharged through the drain outlet. A water pump 7 is fixedly connected to the top of the water storage tank 6. The water inlet pipe at the input end of the water pump 7 is connected to the water storage tank 6, and a cooling pipe 8 is fixedly connected to the output end of the water pump 7. The cooling pipe 8 is distributed in a plurality of continuous S shapes on the top surface of the water storage tank 6, and the other end of the cooling pipe 8 extends into the water storage tank 6. When the movable mold 9 is located at the top of the water storage tank 6, the bottom surface of the movable mold 9 is in contact with the cooling pipe 8. The cooling pipe 8 has a cooling effect on the movable mold 9.

[0030] The opening on the side of the working box 1 is hinged with a box door 2 through a hinge. When the movable mold 9 is completely located in the working box 1, the side of the box door 2 contacts the end surface of the movable mold 9. The movable mold 9 is positioned again through the box door 2.

[0031] The door 2 is provided with a lock 13. The lock 13 is a commonly used anti-theft lock on the anti-theft door. The lock core of the lock 13 is located in the door 2. When the lock core rotates, the lock bolt is controlled to extend and retract through the linkage mechanism to complete the opening and closing action of the door 2.

[0032] Working principle:

[0033] The two limit blocks 11 in the slide slot are named as the first limit block 1101 and the second limit block 1102 respectively.

[0034] Open the box door 2, move the movable mold 9 to the top of the water storage tank 6, and the slide plates 14 correspond to the chutes respectively. Push the mold 9 to the inside of the working box 1, so that the slide plates 14 slide in the chutes.

[0035] When sliding, the end surface of the slide plate 14 will first squeeze the inclined surface at the top of the first limiting block 1101 , and then press the first limiting block 1101 downward, so that the first limiting block 1101 compresses the spring 10 and slides into the inside of the slot 12 .

[0036] Afterwards, one of the limit grooves on the movable mold 9 will slide to the first limit block 1101. When the limit groove is connected to the clamping groove 12 at the first limit block 1101, the spring 10 will push the first limit block 1101 upward under the action of elastic force, so that the first limit block 1101 is clamped in the limit groove.

[0037] Continue to push the mold 9, the slide plate 14 will squeeze the first limit block 1101 again, and then squeeze the second limit block 1102 until the two limit grooves are connected to the corresponding card slots 12 respectively. At this time, the spring 10 will push the limit block 11 into the corresponding limit groove, thereby positioning the slide plate 14.

[0038] The box door 2 is closed, and the side of the box door 2 is brought into contact with the movable mold 9 , and the movable mold 9 is positioned again, and then the box door 2 is fixed by the lock 13 .

[0039] The electric push rod 5 is started, and the telescopic rod of the electric push rod 5 pushes the water storage tank 6 upward, so that the movable mold 9 moves upward until the movable mold 9 abuts against the bottom surface of the fixed mold 3, and the mold is closed. The liquid material can be injected into the gate 4 and enter the fixed mold 3 and the movable mold 9 for molding.

[0040] After molding, the water pump 7 is started to make the water in the water storage tank 6 enter the cooling pipe 8, and the water in the cooling pipe 8 returns to the water storage tank 6 for circulation. The water flowing through the cooling pipe 8 will cool the movable mold 9.

[0041] When the molded product needs to be taken out, the box door 2 is opened, and the mold 9 is pulled outside the working box 1 to make the slide plate 14 slide in the slide groove. When the slide plate 14 slides, it will squeeze the first limit block 1101 and the second limit block 1102, and compress the spring 10. After the movable mold 9 is completely slid out, the limit block 11 is pushed under the action of the spring 10, so that the top of the limit block 11 extends out of the slot 12.

[0042] After the movable mold 9 is slid out, the product can be taken out and the movable mold 9 can be replaced at the same time.

[0043] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
