Description

Technical Field

[0001] This utility model relates to the field of quenching equipment technology, specifically to a mold quenching equipment. Background Technology

[0002] Mold quenching involves placing the mold in a quenching furnace, heating it to above its critical temperature, maintaining this temperature for a period, and then rapidly removing the mold and immersing it in a coolant for quick cooling. In existing technology, heating and cooling are performed in two separate devices. Therefore, workers must remove the heated mold and place it in a cooling chamber. Because the mold surface temperature is high after heating, there is a risk of burns during removal. Furthermore, this process of removing the mold from the heating furnace and placing it in the cooling chamber is inefficient. Therefore, combining the heating furnace and cooling chamber, allowing for rapid cooling after heating, would ensure operational safety and improve work efficiency. Utility Model Content

[0003] In view of this, the present invention provides a mold quenching equipment to solve the technical problem that separating the mold heating and cooling processes not only poses a high risk to operational safety but also makes it difficult to improve work efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A mold quenching device, comprising:

[0006] Quenching box;

[0007] A cooling device connected to the quenching box;

[0008] A lifting mechanism installed on the quenching box, the lifting mechanism including a first drive assembly installed on the quenching box and a lifting assembly connected between the first drive assembly and the quenching box;

[0009] A pair of clamping mechanisms are connected to the lifting assembly. The lifting assembly can control the lifting and lowering of the pair of clamping mechanisms. The clamping mechanism includes a second driving assembly and a clamping limiting assembly. The second driving assembly is connected to the lifting assembly through a Z-shaped support plate. The clamping limiting assembly is connected to the second driving assembly. The second driving assembly and the clamping limiting assembly cooperate to clamp the mold.

[0010] Further, the first driving component includes:

[0011] A drive motor installed on the side of the quenching box;

[0012] A transmission assembly connected to the output end of the drive motor;

[0013] A screw connected to the transmission assembly, the screw being installed inside the quenching chamber.

[0014] Furthermore, the lifting assembly includes:

[0015] A movable seat threadedly connected to the screw, the movable seat being connected to the corresponding Z-shaped support plate;

[0016] A limiting rod is installed inside the quenching box, and the movable seat is slidably engaged with the limiting rod;

[0017] Guide rods installed inside the quenching box;

[0018] A sliding sleeve is slidably mounted on the guide rod, and the sliding sleeve is connected to the corresponding Z-shaped support plate. The sliding sleeve moves synchronously with the movable seat.

[0019] Furthermore, the transmission assembly includes a first bevel gear and a second bevel gear that mesh with each other, the first bevel gear being connected to the output end of the drive motor, and the second bevel gear being connected to the screw.

[0020] Furthermore, the second driving component includes:

[0021] A sliding rod is slidably mounted on the corresponding Z-shaped support plate;

[0022] A pair of sliders fitted onto the slide rod;

[0023] A pair of pull rods, each connected to the corresponding slider;

[0024] An L-shaped handle pivotally connected to a pair of levers;

[0025] A pair of compression springs are sleeved on the slide rod, and the compression springs abut against the corresponding slider and the corresponding Z-shaped support plate;

[0031] A cooling box is installed inside the quenching box, and the water supply pipe is connected to the cooling box;

[0032] A filter screen installed inside the cooling box;

[0033] The water outlet pipe connected to the cooling tank.

[0034] Furthermore, the quenching chamber is equipped with several heating tubes.

[0035] As can be seen from the above technical solution, the advantages of this utility model are:

[0036] 1. This utility model includes a clamping mechanism that can hold the mold in place during both heating and cooling, preventing mold displacement. Furthermore, unlike existing technologies where heating and cooling processes are separate, this utility model integrates these processes. The mold is then moved from heating to cooling without manual handling, making the quenching process safer and more reliable. This integration saves mold handling time compared to existing technologies.

Detailed Implementation

[0046] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0047] refer to Figures 1 to 6 ,like Figure 1 As shown, this embodiment provides a mold quenching device, which consists of a quenching box 1, a cooling device, a lifting mechanism 8, and a pair of clamping mechanisms 9. The front side of the quenching box 1 is hinged with a door 2. By opening the door 2, the mold 100 can be easily placed into and removed from the quenching box 1. The interior of the quenching box 1 is divided into two areas: an upper heating area and a lower quenching area. The size of the door 2 is set according to actual needs. Several heating tubes 11 are installed on the inner wall of the side of the heating area. The several heating tubes 11 are evenly distributed to ensure that the temperature of each position in the heating area is consistent, so that the mold 100 is heated evenly. The cooling device is set in the quenching area. The lifting mechanism 8 is installed on the inner wall of the quenching box 1 and is located between the heating area and the quenching area. A pair of clamping mechanisms 9 are connected to the lifting mechanism 8. The lifting mechanism 8 can control the lifting and lowering of the pair of clamping mechanisms 9. The pair of clamping mechanisms 9 used to clamp the mold 100 can move between the heating area and the quenching area so that the mold 100 can be quickly quenched after heating is completed.

[0048] like Figure 2 and Figure 3As shown, the lifting mechanism 8 consists of a first drive assembly and a lifting assembly. The first drive assembly consists of a drive motor 801, a first bevel gear 802, a second bevel gear 803, and a screw 805. The drive motor 801 is installed on the outer side of the quenching box 1, and the output shaft of the drive motor 801 extends into the quenching box 1. The first bevel gear 802 is connected to the output shaft of the drive motor 801. The second bevel gear 803 is installed at the lower end of the screw 805 and meshes with the first bevel gear 802. The lower end of the screw 805 is connected to the first mounting plate 804 through a bearing seat. The first mounting plate 804 is fixed to the side wall of the quenching box 1. The upper end of the screw 805 is connected to the second mounting plate 808 through a bearing seat. The second mounting plate 808 is fixed to the side wall of the quenching box 1. The first mounting plate 804 and the second mounting plate 808 are spaced apart. The first mounting plate 804 and the second mounting plate 808 ensure that the screw 805 is stably installed on the side wall of the quenching box 1. The lifting assembly consists of a movable seat 806, a limiting rod 807, and a guide rod 809. The movable seat 806 is threaded onto the screw 805 and is connected to one of the clamping mechanisms 9. The limiting rod 807 and the guide rod 809 are distributed parallel to each other at both ends of the heating zone. The movable seat 806 is slidably sleeved on the limiting rod 807. The top of the limiting rod 807 is provided with a positioning block 8071 that can limit the movable seat 806 from rising to the highest point. A sliding sleeve 8091 is slidably sleeved on the guide rod 809 and is connected to another clamping mechanism 9.

[0049] Specifically, Z-shaped support plates 14 are fixedly installed on both the movable seat 806 and the sliding sleeve 8091. The two Z-shaped support plates 14 are symmetrically arranged, and the bottoms of the two Z-shaped support plates 14 are bridged by a connecting frame 15 so that the two Z-shaped support plates 14 can drive the movable seat 806 and the sliding sleeve 8091 to move synchronously.

[0050] The second bevel gear 803 is sleeved on the smooth rod at the lower end of the screw 805. The transmission assembly composed of the first bevel gear 802 and the second bevel gear 803 can transmit the driving force of the drive motor 801 to the screw 805. Then, through the cooperation of a pair of Z-shaped support plates 14, the moving seat 806 and the sliding sleeve 8091 can drive a pair of clamping mechanisms 9 to move up and down synchronously.

[0051] like Figure 2 , Figure 4 and Figure 5As shown, the clamping mechanism 9 consists of a pair of upright plates 901, a second drive assembly, and a clamping and limiting assembly. The pair of upright plates 901 are arranged opposite each other on corresponding Z-shaped support plates 14. The second drive assembly consists of a cylinder 16, a slide rod 903, a pair of sliders 904, a pair of pull rods 905, an L-shaped handle 906, and a pair of compression springs 902. The slide rod 903 is fixed between the pair of upright plates 901, and the sliders 904 are slidably sleeved on the slide rod 903. The pair of sliders 904 are symmetrically distributed front and back. The pull rods 904... 5 is pivotally connected to the L-shaped handle 906 and the corresponding slider 904. A pair of compression springs 902 are sleeved on the slide rod 903. The compression springs 902 abut against the corresponding vertical plate 901 and the corresponding slider 904. The cylinder 16 is installed on the outside of the quenching box 1. A push rod 17 is installed on the cylinder 16. The push rod 17 extends into the quenching box 1. The push rod 17 can push the L-shaped handle 906 to move. The clamping and limiting assembly consists of a pair of limiting clamps 907. The limiting clamps 907 are fixedly connected to the corresponding slider 904.

[0052] Driven by cylinder 16, push rod 17 pushes L-shaped handle 906 to move to the right (reference). Figure 4 and Figure 5 The cylinder 16 allows a pair of pull rods 905 to slide relative to each other along the slide bar 903, compressing the compression spring 902 and simultaneously moving the pair of limiting clamps 907 away from each other, thus releasing the clamping force on the mold 100. Then, the cylinder 16 drives the push rod 17 to reset, eliminating the pressure exerted by the push rod 17 on the L-shaped handle 906. The compression spring 902 then drives the slider 904 to reset the limiting clamps 907, restoring their clamping force on the mold 100. Therefore, before placing the mold 100, the cylinder 16 pushes the L-shaped handle 906, increasing the distance between the pair of limiting clamps 907. After placing the mold 100, the cylinder 16 resets, releasing the pressure of the push rod 17 on the L-shaped handle 906, thus resetting the compression spring 902 and allowing the pair of limiting clamps 907 to clamp the mold 100.

[0053] Preferably, the limiting clamping plate 907 is provided with a pad 908, which has anti-slip texture to increase friction and enhance the clamping effect, while preventing the limiting clamping plate 907 from directly contacting the mold 100 and causing wear on the limiting clamping plate 907 or the mold 100. This can protect the limiting clamping plate 907 and the mold 100.

[0054] like Figure 1 and Figure 2As shown, the cooling device consists of a condenser 4, a cooling tank 6, a filter screen 13, and a water outlet pipe 12. The condenser 4 is located on the side of the quenching tank 1, and the cooling tank 6 is located in the quenching zone. One end of the condenser 4 is connected to the water inlet pipe 3, which is connected to a water source. The other end of the condenser 4 is connected to the cooling tank 6 through the water delivery pipe 5. The other side of the cooling tank 6 is equipped with a water outlet pipe 12. One-way valves are installed on the water inlet pipe 3, the water delivery pipe 5, and the water outlet pipe 12, so that the coolant can only flow in through the water inlet pipe 3 and flow out through the water outlet pipe 12. In addition, a filter screen 13 is installed inside the cooling tank 6. During the quenching process, dirt and debris on the surface of the mold 100 will fall into the quenching pool 18. The filter screen 13 can collect dirt and debris, so that the coolant can be reused.

[0055] The inlet pipe 3 delivers the liquid to the condenser 4, which cools the liquid to make it a coolant. The coolant is then delivered to the cooling tank 6 through the water supply pipe 5 to cool the mold 100. After multiple quenchings, the coolant is discharged through the outlet pipe 12 for recycling.

[0056] like Figure 6 As shown, a pair of support blocks 7 are symmetrically arranged on the inner wall of the cooling box 6. The filter screen 13 is installed on the upper part of the support blocks 7. When the filter screen 13 needs to be cleaned, it can be removed by clamping it in the mesh of the filter screen 13. The operation is convenient and simple. When installing the filter screen 13, it is only necessary to place it on the pair of support blocks 7.

[0057] Working principle: A pair of cylinders 16 are activated, pushing a pair of L-shaped handles 906 towards the center via a pair of push rods 17. This increases the front-to-back distance between the two pairs of limiting clamps 907. After opening the box door 2, the mold 100 is placed between a pair of Z-shaped support plates 14, positioning the mold 100 between the two pairs of limiting clamps 907. The cylinders 16 are then reset, causing the push rods 17 to release their grip on the L-shaped handles 906. The left pair of limiting clamps 907 then clamps the left end of the mold 100 at both the front and back sides, while the right pair of limiting clamps 907 clamps the right end of the mold 100 at both the front and back sides, thus securing the mold 100. The box door 2 is then closed, and the equipment operation begins. The automatic operation (controlled by the controller) involves moving the mold 100 to the heating zone via the drive motor 801. The mold 100 is heated by the heating tube 11. Once the temperature reaches the set value (this process is controlled by the controller), the drive motor 801 starts, driving the screw 805 to rotate via the transmission assembly. The moving seat 806 and the sliding sleeve 8091 then lower the mold 100 via a pair of Z-shaped support plates 14 until the mold 100 enters the quenching pool 18 of the cooling box 6 for quenching. After cooling, the drive motor 801 is started, causing the pair of Z-shaped support plates 14 to move the mold 100 upward. Finally, the box door 2 is opened to remove the mold 100.
