Description

Technical Field

[0001] The utility model relates to the technical field of metal die-casting machines, and specifically relates to a rapid demoulding structure for aluminum alloy die-castings. Background Art

[0002] An aluminum alloy die-casting machine is a device used in the aluminum alloy die-casting process. Aluminum alloy die-casting refers to the process of pressing aluminum alloy materials into a mold through the pressure of a die-casting machine, so that the aluminum alloy materials are formed into the required shapes, and finally aluminum alloy parts with high strength, high precision and smooth surface are formed.

[0003] The prices of existing high-quality materials such as aluminum alloys are relatively high, and losses during production must be strictly controlled. Otherwise, the cost of workpieces will become very high. During die-casting, operators need to remove the castings from the mold. Since the castings have just undergone severe extrusion, they will become extremely hot, posing a safety hazard to the operators. Waiting for the castings to cool down before taking them out ensures safety, but the efficiency will be greatly reduced. The reduction in efficiency means an increase in cost. At the same time, unqualified castings will jam the mold, and manual cleaning is time-consuming and laborious, and there is also a risk of being scratched. Therefore, we propose a rapid demoulding structure for aluminum alloy die-castings to solve the above problems. Summary of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a rapid demoulding structure for aluminum alloy die-castings, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the utility model is realized through the following technical solutions: A rapid demoulding structure for aluminum alloy die-castings includes two groups of mold shells. An active chassis is arranged inside the two groups of mold shells. Wedge-shaped sliders are fixedly installed at the bottoms of the two groups of mold shells. A top block is fixedly connected to the bottom of the active chassis. The wedge-shaped sliders are movably inserted into the inner bottom of the top block, and the wedge-shaped sliders are used to lift the top block and the active chassis.

[0006] One side of the wedge-shaped slider is fixedly connected to a steel cable, and the two steel cables are used to pull the two groups of mold shells towards the middle.

[0007] The other side of the wedge-shaped slider is fixedly connected to a spring, and the two springs are used to pull the two groups of mold shells apart to both sides.

[0008] Preferably, a guide block is movably sleeved at the bottom of the top block, and the guide block is used to guide the movement of the top block.

[0009] Preferably, a machine body is arranged outside the demoulding structure, and a hydraulic mechanism is arranged inside the machine body.

[0010] Preferably, a fixing block is fixedly installed on one side of the spring, the fixing block is fixedly installed at the bottom of the machine body, a guiding column is movably sleeved inside the spring, and the guiding column is used to guide the movement of the spring.

[0011] Preferably, a high-strength spring is arranged in the middle of the steel cable, and the other side of the steel cable is fixedly connected to the bottom of the hydraulic mechanism.

[0012] Preferably, a plurality of pulley shafts are rotatably connected inside the machine body, one end of the pulley shaft is rotatably connected with a pulley, and a steel cable is wound inside the pulley.

[0013] The utility model discloses a rapid demoulding structure for aluminum alloy die-castings, and the beneficial effects thereof are as follows:

[0014] When this structure is in use, the hydraulic press presses downwards, the steel cable pulls the wedge-shaped slider, pulls the two die-casting mold shells towards the middle, and at the same time makes the movable chassis move downwards to complete the automatic assembly of the die-casting mold. After the casting is stamped, the hydraulic press moves upwards, the steel cable connected to the hydraulic press is relaxed, the spring on the wedge-shaped slider pulls the two die-casting mold shells apart, and at the same time the wedge-shaped slider jacks up the top block and the movable chassis together, driving the casting to rise together to complete demoulding. This structure is ingeniously designed and reasonably constructed. At the same time, the semi-open structure facilitates the operation of technicians and the later maintenance and repair of maintenance personnel. The rapid demoulding saves costs at the same time. Unqualified castings will also be directly ejected, avoiding the problem of unqualified castings jamming the mold, and meeting the needs of users. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The embodiment of the present utility model discloses a rapid demoulding structure for aluminum alloy die castings.

[0025] As shown in the attachment Figures 1-4 It includes two groups of mold shells 1. A movable chassis 2 is arranged inside the two groups of mold shells 1. Wedge-shaped sliders 3 are fixedly installed at the bottom of the two groups of mold shells 1. A top block 4 is fixedly connected to the bottom of the movable chassis 2. The wedge-shaped sliders 3 are movably inserted into the inner bottom of the top block 4. The wedge-shaped sliders 3 are used to jack up the top block 4 and the movable chassis 2.

[0026] One side of the wedge-shaped slider 3 is fixedly connected to a steel cable 10. The two groups of steel cables 10 are used to pull the two groups of mold shells 1 towards the middle.

[0027] The other side of the wedge-shaped slider 3 is fixedly connected to a spring 9. The two groups of springs 9 are used to pull the two groups of mold shells 1 apart to both sides. When this structure is in use, the hydraulic press presses downwards. The steel cable 10 connected to the hydraulic press is slowly tightened through the pulley 12. The steel cable 10 pulls the wedge-shaped slider 3, pulling the two groups of mold shells 1 towards the middle. After the casting is stamped, the hydraulic press moves upwards, the steel cable 10 connected to the hydraulic press is relaxed, the spring 9 on the wedge-shaped slider 3 pulls the two groups of mold shells 1 apart, and at the same time the wedge-shaped slider 3 jacks up the top block 4 and the movable chassis 2 together, driving the casting to rise together to complete demoulding.

[0028] A guide block 5 is movably sleeved at the bottom of the top block 4. The guide block 5 is used to guide the movement of the top block 4. The top block 4 has an opening at the bottom, and the guide block 5 arranged in the hole enables it to move only up and down. At the same time, the guide block 5 is fixed to the bottom of the machine body 6, fixing the position of the top block 4 and avoiding the problem that the top block 4 is displaced due to the vibration generated by machine stamping, thereby damaging the casting.

[0029] A machine body 6 is arranged outside the demolding mechanism, and a hydraulic mechanism 14 is arranged inside the machine body 6.

[0030] A fixed block 7 is fixedly installed on one side of the spring 9, and the fixed block 7 is fixedly installed at the bottom of the machine body 6. A guide post 8 is movably sleeved inside the spring 9, and the guide post 8 is used to guide the movement of the spring 9.

[0031] A high-strength spring 13 is arranged in the middle of the steel cable 10. The other side of the steel cable 10 is fixedly connected to the bottom of the hydraulic mechanism 14. The high-strength spring 13 arranged on the steel cable 10 reduces the wear of the steel cable 10, and the stretchable and contractible high-strength spring 13 can better adapt to the stamping process.

[0032] A plurality of pulley shafts 11 are rotatably connected inside the machine body 6. One end of the pulley shaft 11 is rotatably connected with a pulley 12, and a steel cable 10 is wound inside the pulley 12.
