[0018] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] A car handle box mold, such as Figure 1 - Figure 4 As shown, it includes a compression molding workbench 1, and a lower compression mold 7, an upper compression mold 3 and a cylinder 5 located above the compression molding workbench 1. A cooling shell 2 is fixedly connected to the compression molding workbench 1, and the cooling shell 2 is set as an opening 203 shell. The lower compression mold 7 is slidably connected to the inner wall of the cooling shell 2, and the lower compression mold 7 can be away from or close to the inner bottom surface of the cooling shell 2. A cooling pool 4 is fixedly connected to the compression molding workbench 1. A water pump 1 6 and a water pump 2 8 are set in the cooling pool 4. Two openings 203 are opened on the side wall of the cooling shell 2. The cooling liquid exchange between the cooling pool 4 and the cooling shell 2 is realized through the opening 203, the water pump 1 6 and the water pump 2 8. The cooling cavity 10 formed between the cooling shell 2 and the lower compression mold 7 cooperates with the cooling pool 4 and the water pump 1 6 and the water pump 2 8 to exchange the cooling liquid in the cooling shell 2 and the cooling pool 4, so as to realize the physical cooling of the lower compression mold 7 by the coolant, accelerate the cooling speed of the product after molding, and improve the efficiency of the compression molding operation.

[0020] like Figure 1 and Figure 2 As shown, the cooling shell 2 is fixedly connected to the compression molding workbench 1, and a plurality of limiting rods 9 are fixedly connected to the top surface of the cooling shell 2, a fixing plate 11 is slidably connected to the limiting rods 9, an upper pressure mold 3 is fixedly connected to the end surface of the fixing plate 11 close to the cooling shell 2, and a cylinder 5 is fixedly connected to the top surface of the fixing plate 11. When the cylinder 5 is pressed downward, it drives the fixing plate 11 and the upper pressure mold 3 to move toward the cooling shell 2, and the upper pressure mold 3 and the lower pressure mold 7 fit together to form a cavity.

[0021] like Figure 2 , Figure 3 and Figure 4As shown, the cooling shell 2 is configured as an opening 203 shell, and a receiving cavity 201 is provided inside its side wall, and a plurality of hydraulic rods 12 are fixedly connected inside the receiving cavity 201, and a plurality of sliding grooves 202 are provided on the inner wall of the cooling shell 2, and the sliding grooves 202 are connected to the receiving cavity 201, and a sliding sheet 701 is fixedly connected to the side wall of the lower pressing mold 7, and the sliding sheet 701 is annular, and the sliding sheet 701 is located in the receiving cavity 201 and is fixedly connected to the top of the rod body of the hydraulic rod 12, and a connecting piece is provided between the sliding sheet 701 and the lower pressing mold 7, and the connecting piece is slidably connected in the sliding groove 202. When the compression molding operation is performed, when the upper pressing mold 3 and the lower pressing mold 7 are abutted, the hydraulic rod 12 is pressed and the lower pressing mold 7 continues to move toward the bottom of the cooling shell 2, and when the bottom of the lower pressing mold 7 abuts against the inner bottom surface of the cooling shell 2, the upper pressing mold 3 continuously extrude the material in the lower pressure mold 7 to complete the compression molding of the product. The sliding sheet 701 and the plurality of hydraulic rods 12 are used to improve the stability of the upper pressure mold 3 and the lower pressure mold 7 during the compression molding process, improve the stability of product molding, and improve the yield rate. After the compression molding is completed, the cylinder 5 drives the upper pressure mold 3 to move upward, and the hydraulic rod 12 releases the pressure to drive the lower pressure mold 7 away from the bottom of the cooling shell 2. The volume of the cooling cavity 10 between the cooling shell 2 and the lower pressure mold 7 becomes larger and can accommodate more coolant to physically cool the lower pressure mold 7. Preferably, the maximum distance between the bottom surface of the cooling shell 2 and the bottom surface of the lower pressure mold 7 is greater than 10 cm, and the maximum distance between the inner wall of the cooling shell 2 and the outer wall of the lower pressure mold 7 is greater than 10 cm. The setting of the distance can allow more coolant to enter the cooling cavity 10, thereby improving the cooling effect after the compression molding operation.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the upper pressure mold 3, the lower pressure mold 7 and the cooling shell 2 are made of P20 steel. The good thermal conductivity, mechanical properties and high strength of P20 steel are used to increase the service life of the entire mold, increase the cooling speed of the lower pressure mold 7, and improve the molding efficiency of the product.

[0023] like Figure 2 , Figure 3 and Figure 4As shown, the cooling pool 4 is fixedly connected to the top surface of the compression molding workbench 1, and a water pump 1 6 and a water pump 2 8 are fixedly connected to the side wall of the cooling pool 4. The water inlet of the water pump 1 6 and the water outlet of the water pump are connected to the cooling pool 4. Two openings 203 are arranged on the side wall of the cooling shell 2, and the openings 203 penetrate the outer wall of the cooling shell 2. The water outlet of the water pump 1 6 and the water inlet of the water pump 2 8 are connected to the two openings 203 respectively. When the compression molding operation is performed, the coolant in the cooling chamber 10 is extracted by the water pump 2 8, which facilitates the upper compression mold 3 to pressurize the lower compression mold 7 to ensure the stability during the compression molding operation. After the compression molding operation is completed, the cylinder 5 drives the upper compression mold 3 to move, and the distance between the lower compression mold 7 and the cooling shell 2 gradually increases. The coolant in the cooling pool 4 is pumped into the cooling chamber 10 by the water pump 1 6, and the coolant in the cooling chamber 10 is pumped into the cooling pool 4 by the water pump 2 8. Preferably, the water pump 1 6 and the water pump 2 The flow rate of water pump 2 8 is 25 cubic meters per hour to 50 cubic meters per hour. The flow rate setting ensures that the lower pressure mold 7 can be quickly cooled after the compression molding operation is completed. Preferably, the flow rate of water pump 2 8 is less than the flow rate of water pump 1 6. The flow rate setting of water pump 1 6 and water pump 2 8 can speed up the flow rate of the liquid in the cooling chamber 10, and speed up the exchange rate between the coolant in the cooling chamber 10 and the coolant in the cooling pool 4. The coolant in the cooling pool 4 is in contact with the outside world for cooling, and cooling the lower pressure mold 7 by the coolant has the characteristics of low cost, fast cooling speed and convenient maintenance. The setting of the flow difference can ensure that the liquid in the cooling chamber 10 is at a higher horizontal position, so that the coolant in the cooling chamber can wrap more of the lower pressure mold 7. By increasing the contact area between the outer wall of the lower pressure mold 7 and the coolant, the cooling speed of the lower pressure mold 7 after the compression molding operation is improved, and the molding speed of the product is improved.

[0024] Working principle: When the automobile handle box mold is used for compression molding, the cylinder 5 is started to pull the fixed plate 11 and the upper pressure mold 3 upward to position, and then the preheated material is placed in the lower pressure mold 7. The cylinder 5 is started to move the fixed plate 11 and the upper pressure mold 3 closer to the lower pressure mold 7, and the upper pressure mold 3 fits with the lower pressure mold 7, and a cavity of the handle box structure is formed between the upper pressure mold 3 and the lower pressure mold 7. The material in the lower pressure mold 7 is deformed, and the water pump 6 is turned on to continuously pump the coolant in the cooling pool 4 into the cooling shell 2 to cool the material. The liquid is relative to the outer wall of the lower pressure mold 7, and the lower pressure mold 7 is physically cooled. The water pump 2 8 continuously pumps the liquid in the cooling shell 2 into the cooling pool 4, and the lower pressure mold 7 is continuously cooled by the flowing coolant. When the cylinder 5 works to drive the fixed plate 11 and the upper pressure mold 3 to move upward, the water pump 1 6 and the water pump 2 8 continue to work, and the volume of the cooling cavity 10 gradually increases, which can accommodate more coolant, thereby accelerating the cooling speed of the lower pressure mold 7. Finally, the buckle box workpiece that has been formed and cooled is taken out, and a compression molding operation is completed.
