Description

Technical Field

[0001] The invention relates to the technical field of die-casting processing, and in particular to a demoulding device for processing a spotlight shell and a use method thereof. Background Art

[0002] Sufficient cooling time must be ensured when demolding the die casting process. The casting needs to be fully cooled after die casting so that its internal structure is stable and shrinks into place. If the cooling time is too short, the casting has not been fully formed and is prone to deformation during demolding. If the cooling time is too long, production efficiency will be reduced. Generally, the cooling time is determined based on factors such as the wall thickness, material and mold structure of the casting. For example, for aluminum alloy or magnesium alloy castings with a wall thickness of 2mm, the cooling time may be around 10-20 seconds.

[0003] In the prior art, water cooling is a commonly used method. However, for special-shaped die-casting molds, the mold wall thickness is uneven, so water cooling cannot achieve uniform cooling, and there will be local temperature differences, which will cause poor local heat dissipation of the die-casting. If the initial temperature of the refrigerant is increased, the temperature difference will be further aggravated, which will cause local warping of the die-casting. If the cooling time is increased, it will affect the production efficiency. For this reason, a demolding device for spotlight shell processing and a method of using the same are proposed. Summary of the invention

[0004] The purpose of the present invention is to provide a demoulding device for processing a spotlight housing and a method of using the same in order to solve the above problems, as described below.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] The present invention provides a demoulding device for processing a spotlight housing and a method for using the same, comprising a base, on which a mold mechanism for die-casting a finished product and an unfolding mechanism for unfolding the mold mechanism are arranged;

[0007] The mold mechanism comprises a core mold arranged on a base, a top mold located on the top of the core mold, and two side molds capable of wrapping the core mold;

[0008] The base is provided with a water-cooling heat dissipation component for dissipating heat from the two side molds;

[0009] The water-cooling heat dissipation component includes two shells, which are respectively fixed on the surfaces of two side molds, and a plurality of heat dissipation grooves are opened on the side molds, and the shells wrap the heat dissipation grooves, and a coolant that can flow is arranged in the shells;

[0010] The base is provided with an air-cooling heat dissipation component for conveying air between the inner wall of the side mold and the surface of the finished product.

[0011] The above-mentioned demoulding device for processing a spotlight housing is used to die-cast the material into the mold mechanism. After the die-casting is completed, the side mold is cooled by a water-cooling heat dissipation component to accelerate the solidification speed of the finished product. Since the surface of the finished product is in contact with the side mold, the position where the finished product contacts the side mold can solidify first.

[0012] After the water-cooling heat dissipation component has been running for a period of time, the two side molds are moved by the unfolding mechanism to create a certain distance between them and the finished product. Then, the air is transported between the finished product and the side molds by the air-cooling heat dissipation component. The fluidity of the airflow can fully dissipate heat on the surface of the finished product, accelerating the finalization of the finished product.

[0013] After the finished product is finalized, the mold mechanism is fully unfolded through the unfolding mechanism, and then the finished product can be taken out.

[0014] Preferably, the water-cooling heat dissipation component includes a water tank radiator and a circulation pump, the water tank radiator is arranged on a base, the water pumping end of the circulation pump is connected to the water tank radiator, the water outlet end of the circulation pump is connected to one of the two shells through circulation pipe 2, the other shell is connected to the water tank radiator through circulation pipe 1, and the two shells are connected through a connecting pipe.

[0015] Preferably, the unfolding mechanism includes a fixed frame, which is fixed on the base, and on which an electric push rod 1 is vertically arranged and two electric push rods 2 are horizontally arranged. The movable end of the electric push rod 1 is fixed to the top mold, and the movable end of the electric push rod 2 is fixed to the shell.

[0016] Preferably, the air-cooled heat dissipation component includes a fan, which is arranged on a base. Channel 1 and channel 2 are opened on the side mold, channel 1 penetrates the side mold, channel 2 is connected with channel 1, a sealing rod is inserted in channel 1 for sealing channel 1 and channel 2, and the output end of the fan is connected with the two channels 2 respectively through two air supply pipes.

[0017] Preferably, a filter element is provided at the air inlet of the fan.

[0018] Preferably, a spring is sleeved on the surface of the sealing rod, and two ends of the spring are respectively fixed to the sealing rod and the side mold.

[0019] Preferably, a fixing rod is fixed to the end of the sealing rod away from the side mold, and a driving assembly is provided on the base. When the unfolding mechanism drives the two side molds away from each other, the sealing rod can be moved by cooperating with the fixing rod and the driving assembly, so that the sealing rod is misaligned with channel 2.

[0020] Preferably, the driving assembly comprises a mounting frame, on which two guide blocks are arranged, the two guide blocks are symmetrical to each other, and a side of the guide block corresponding to the fixing rod is an inclined surface.

[0021] Preferably, the end of the sealing rod inserted into channel one is flush with the inner wall of the side mold.

[0022] A method for using a demoulding device for processing a spotlight housing is carried out according to the following steps:

[0023] (1) The material is die-casted into the mold mechanism. After die-casting is completed, the side mold is cooled by a water-cooling heat dissipation component to accelerate the solidification speed of the finished product. Since the surface of the finished product is in contact with the side mold, the position where the finished product contacts the side mold can solidify first;

[0024] (ii) After the water-cooling heat dissipation component has been running for a period of time, the two side molds are moved by the unfolding mechanism to create a certain distance between them and the finished product, and then the air-cooling heat dissipation component is used to transport air between the finished product and the side molds. The fluidity of the airflow can fully dissipate heat on the surface of the finished product, thereby accelerating the finalization of the finished product;

[0025] (3) After the finished product is finalized, the mold mechanism is fully unfolded through the unfolding mechanism, and then the finished product can be taken out.

[0026] The beneficial effects are:

[0027] 1. The water-cooling heat dissipation component is used to cool the side mold to accelerate the solidification speed of the finished product. Since the surface of the finished product is in contact with the side mold, the position where the finished product contacts the side mold can solidify first. After the water-cooling heat dissipation component has been running for a period of time, the two side molds are moved by the unfolding mechanism to create a certain distance between them and the finished product. The air is transported between the finished product and the side mold through the air-cooling heat dissipation component. The fluidity of the air flow can fully dissipate heat on the surface of the finished product, which can adapt to special-shaped die-casting workpieces and accelerate the finalization of the finished product, which not only improves production efficiency, but also ensures the quality of die-casting demoulding;

[0028] 2. When the unfolding mechanism drives the two side molds away from each other, the sealing rod can be moved by cooperating with the fixed rod and the driving assembly, so that the sealing rod is misaligned with channel two. During die-casting, the sealing rod needs to seal channel one. When the air-cooled heat dissipation assembly needs to dissipate heat, the sealing rod needs to release the blockage of channel two. This design enables the sealing rod to move automatically according to the step of the device, thereby reducing the operating steps of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] See also Figure 1-Figure 6 As shown, the present invention provides a demoulding device for processing a spotlight housing, comprising a base 1, on which a mold mechanism 2 for die-casting a finished product 6 and an unfolding mechanism 7 for unfolding the mold mechanism 2 are arranged;

[0040] The mold mechanism 2 includes a core mold 3 arranged on a base 1, a top mold 5 located on the top of the core mold 3, and two side molds 4 capable of wrapping the core mold 3, and a die-casting hole is arranged on the top mold 5;

[0041] A water-cooling heat dissipation component 11 is provided on the base 1 for dissipating heat from the two side molds 4;

[0042] The water-cooling heat dissipation assembly 11 includes two shells 16, which are respectively fixed on the surfaces of the two side molds 4. A plurality of heat dissipation grooves 18 are provided on the side molds 4, and the shells 16 wrap the heat dissipation grooves 18. A coolant that can flow is provided in the shells 16. The coolant contacts the side molds 4 and can absorb the heat of the side molds 4. The heat dissipation grooves 18 can increase the contact area between the coolant and the side molds 4.

[0043] An air-cooling heat dissipation component 19 is provided on the base 1 for conveying air between the inner wall of the side mold 4 and the surface of the finished product 6. The air-cooling heat dissipation component 19 can further improve the heat dissipation efficiency of the device, and utilize the fluidity of the wind to fully dissipate the heat on the surface of the finished product 6.

[0044] As an optional embodiment, the water-cooling heat dissipation component 11 includes a water tank radiator 13 and a circulation pump 14. The water tank radiator 13 is arranged on the base 1. The water pumping end of the circulation pump 14 is connected to the water tank radiator 13. The water outlet end of the circulation pump 14 is connected to one of the two shells 16 through the circulation pipe 2 15. The other shell 16 is connected to the water tank radiator 13 through the circulation pipe 1 12. The two shells 16 are connected through the connecting pipe 17.

[0045] The water tank radiator 13 includes a cooling fan, and the coolant is made to flow in the two shells 16 through the circulation pump 14. After the coolant carrying heat flows into the water tank radiator 13, the heat of the coolant can be dissipated into the air through the water tank radiator 13.

[0046] The unfolding mechanism 7 includes a fixing frame 8, the fixing frame 8 is fixed on the base 1, an electric push rod 1 9 is vertically arranged on the fixing frame 8, and two electric push rods 2 10 are horizontally arranged, the movable end of the electric push rod 1 9 is fixed to the top mold 5, and the movable end of the electric push rod 2 10 is fixed to the housing 16;

[0047] The shell 16 can be moved by two electric push rods 10, and then the side mold 4 can be moved by the shell 16 until the side mold 4 is completely separated from the finished product 6. After the two side molds 4 are unfolded, the top mold 5 is driven to move upward by the electric push rod 9.

[0048] The air-cooling heat dissipation component 19 includes a fan 20, which is arranged on the base 1. A channel 1 22 and a channel 2 23 are opened on the side mold 4. The channel 1 22 runs through the side mold 4, and the channel 2 23 is connected to the channel 1 22. A sealing rod 24 is inserted into the channel 1 22 to block the channel 1 22 and the channel 2 23. The output end of the fan 20 is connected to the two channels 2 23 through two air supply pipes 21 respectively;

[0049] The fan 20 can deliver the airflow to between the side mold 4 and the finished product 6 through the air supply pipe 21 and the second channel 23 .

[0050] The air inlet of the fan 20 is provided with a filter element 28 , which is used to filter dust and prevent the airflow carrying dust from entering the mold mechanism 2 .

[0051] A spring 30 is sleeved on the surface of the sealing rod 24, and both ends of the spring 30 are fixed to the sealing rod 24 and the side mold 4 respectively. The spring 30 can keep the sealing rod 24 stationary, and the elastic force of the spring 30 is greater than the die-casting pressure. Therefore, during die-casting, the sealing rod 24 will not be pushed by the material.

[0052] A fixing rod 29 is fixed to the end of the sealing rod 24 away from the side mold 4, and a driving assembly 25 is provided on the base 1. When the unfolding mechanism 7 drives the two side molds 4 away from each other, the sealing rod 24 can be moved by cooperating with the fixing rod 29 and the driving assembly 25, so that the sealing rod 24 and the channel 2 23 are misaligned. During die-casting, the sealing rod 24 needs to seal the channel 1 22. When the air-cooled heat dissipation assembly 19 needs to dissipate heat, the sealing rod 24 needs to release the blockage of the channel 2 23. This design enables the sealing rod 24 to move automatically according to the step of the device, thereby reducing the operating steps of the device.

[0053] The driving assembly 25 includes a mounting frame 26, on which two guide blocks 27 are arranged. The two guide blocks 27 are symmetrical to each other, and one side of the guide block 27 corresponding to the fixing rod 29 is an inclined surface.

[0054] When the sealing rod 24 moves with the two side molds 4, the sealing rod 24 will drive the fixing rod 29 to contact the guide block 27. The inclined surface of the guide block 27 cooperates with the fixing rod 29 to pull the sealing rod 24 out of the channel 1 22, and the spring 30 can insert the sealing rod 24 into the channel 1 22 again.

[0055] The end of the sealing rod 24 inserted into the channel 1 22 is flush with the inner wall of the side mold 4, thus ensuring that the surface of the finished product 6 is smooth.

[0056] A method for using a demoulding device for processing a spotlight housing is carried out according to the following steps:

[0057] (i) The material is die-casted into the mold mechanism 2. After die-casting is completed, the side mold 4 is cooled by the water cooling component 11 to accelerate the solidification speed of the finished product 6. Since the surface of the finished product 6 is in contact with the side mold 4, the position where the finished product 6 contacts the side mold 4 can solidify first;

[0058] (ii) After the water-cooling heat dissipation component 11 has been running for a period of time, the two side molds 4 are moved by the unfolding mechanism 7 to create a certain distance between them and the finished product 6, and then the air-cooling heat dissipation component 19 delivers air to between the finished product 6 and the side molds 4. The fluidity of the airflow can fully dissipate heat at various locations on the surface of the finished product 6, thereby accelerating the shaping of the finished product 6;

[0059] (iii) After the finished product 6 is finalized, the mold mechanism 2 is fully unfolded by the unfolding mechanism 7, and then the finished product 6 can be taken out.

[0060] With the above structure, the material is die-casted into the mold mechanism 2. After die-casting is completed, the side mold 4 is cooled by the water cooling component 11 to accelerate the solidification speed of the finished product 6. Since the surface of the finished product 6 is in contact with the side mold 4, the position where the finished product 6 contacts the side mold 4 can solidify first.

[0061] After the water-cooling heat dissipation component 11 has been running for a period of time, the two side molds 4 are moved by the unfolding mechanism 7 to create a certain distance between them and the finished product 6, and then the air-cooling heat dissipation component 19 delivers air to between the finished product 6 and the side molds 4, and the fluidity of the air flow can fully dissipate heat at various places on the surface of the finished product 6, thereby accelerating the shaping of the finished product 6;

[0062] After the finished product 6 is formed, the mold mechanism 2 is fully unfolded by the unfolding mechanism 7, and then the finished product 6 can be taken out.
