Description

Technical Field

[0001] The invention relates to the technical field of gear processing, in particular to a temperature control device for a bevel gear production mold. Background Art

[0002] Gears have always been an important mechanical part. Through the meshing and cooperation of multiple sets of transmission gears, the linkage of various mechanical mechanisms can be realized, thereby completing some complex mechanical movements. In the production process of gears, forging and mold casting are usually used. In the process of mold molding, it is usually necessary to control the temperature generated during casting and the cooling time to ensure that the produced gears meet the use requirements. Poor thermal balance of the mold will cause deformation, thermal cracking, mold sticking and other phenomena in the product. This phenomenon not only affects the firmness and durability of the produced gears, but also causes a certain degree of damage to the mold. Therefore, it is necessary to monitor the temperature generated during casting in real time, and then appropriately reduce it according to the molding effect. Temperature and heating, the patent with application number CN112223659A discloses an injection mold for gears that is easy to open the mold. The mold realizes the opening and closing of the mold by using structures such as a driving motor, a small connecting wheel, and a large connecting wheel. However, the technical party did not propose the use of cooling and heating mechanisms to ensure that the gears will not have thermal cracking and mold sticking during the production process. Therefore, during the casting and gear molding process, it can only be heated and cooled by external equipment. This method not only increases the labor intensity of the personnel, but also the temperature cannot be well controlled and the speed is slow. It will also cause uneven heating, and the temperature cannot be controlled in time. Therefore, the produced gears will still have certain defects. Summary of the invention

This method not only increases the labor intensity of personnel, but also the temperature cannot be well controlled.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a temperature control device for a bevel gear production mold, comprising a base, characterized in that: a support rod is fixedly connected to the upper surface of the base, a display screen is fixedly connected to the upper end of the support rod, an operation keyboard is arranged on the display screen, a lower mold is fixedly connected to the upper surface of the base, an upper mold is arranged on the lower mold, a lower molding cavity is opened on the upper surface of the lower mold, an upper molding cavity is opened on the lower surface of the upper mold, a through hole is opened on the upper surface of the upper mold, the through hole is connected to the upper molding cavity, a vacuum tube is fixedly connected inside the through hole, and a temperature control device is arranged on the lower mold;

[0009] Auxiliary grooves are provided on both sides of the positioning rod, and a spring is also fixedly connected inside the auxiliary groove. The end of the spring that does not contact the inner wall of the auxiliary groove is fixedly connected to the fixing rod. A fixing hole that matches the fixing rod is provided on the inner wall of the built-in groove 2, and the positioning rod is cylindrical.

[0010] Preferably, a temperature control device is also provided on the lower surface of the upper mold, and the temperature control device provided on the upper mold has the same structure as the temperature control device provided on the lower mold.

[0011] Preferably, the base is fixedly connected to a connecting motor inside, the output end of the motor is fixedly connected to a first gear, the upper surface of the lower mold is provided with two rotating holes, the insides of the two rotating holes are rotatably connected to threaded rods, the lower ends of the two threaded rods extend to the inside of the base, the lower ends of the two threaded rods are fixedly connected to a second gear, and the two second gears are connected to the first gear by a chain.

[0012] Preferably, the lower surface of the upper mold is provided with two threaded holes which are adapted to the two threaded rods, and the upper ends of the two threaded rods are threadedly connected to the inside of the two threaded holes.

[0013] Preferably, a push plate is slidably connected inside the lower molding cavity, a temperature sensor and a detector are arranged inside the push plate, and both the temperature sensor and the detector are connected to the display screen for signal transmission.

[0014] Compared with the prior art, the present invention provides a temperature control device for a bevel gear production mold, which has the following beneficial effects:

[0015] 1. The temperature control device for the bevel gear production mold can observe and detect the temperature and molding conditions of the gears inside the upper molding cavity and the lower molding cavity through the set temperature sensors and detectors, and then the detection data is displayed on the display screen. When the gears inside the upper molding cavity and the lower molding cavity need to be heated and cooled again, the heating tube and the condenser are controlled by the operation keyboard to ensure the molding effect and avoid the fracture caused by uneven condensation. At the same time, the start of the condenser can accelerate the molding of the gear and play a cooling effect, thereby increasing the molding speed of the gear and improving the production efficiency. The heating tube and the condenser are set crosswise, so that the temperature that the gear is exposed to during heating and cooling is more uniform, thereby ensuring the molding effect of the gear and reducing the occurrence of defective products, thereby reducing the waste of raw materials and reducing cost expenditure, thereby ensuring that the mold will not be damaged and ensuring that the produced gear meets the use requirements.

[0016] 2. The temperature control device for the bevel gear production mold is movably connected to the inside of the slot through the provided clamping block, so as to facilitate the maintenance and replacement of the heating tube and the condenser. At the same time, the blocking of the slot by the clamping block can effectively prevent dust and foreign objects from entering the inside of the slot to damage the heating tube and the condenser, thereby increasing the service life of the heating tube and the condenser and reducing the cost of replacement and maintenance.

[0017] 3. The temperature control device for the bevel gear production mold is equipped with a vacuum tube. When the bevel gear needs to be injection molded, the liquid can be poured into the upper molding cavity and the lower molding cavity through the vacuum tube. At the same time, an external vacuum extractor can be connected to the vacuum tube to extract the air inside the upper molding cavity and the lower molding cavity, thereby reducing the bubbles inside the bevel gear after molding, thereby improving the firmness of the gear after molding and the stability during use, and at the same time improving the production yield.

[0018] 4. The temperature control device for the bevel gear production mold uses a set motor. When the gear needs to be taken out after forming, the motor is started, and the output end of the motor rotates, which drives the first gear to rotate. The rotation of the first gear causes the chain to drive the second gear to rotate, and the second gear drives the threaded rod to rotate. The rotation of the threaded rod causes the upper mold to move upward, so that the upper mold is separated from the lower mold, and the upper mold and the lower mold are completely separated, so that it is convenient to take out the gear, and it is no longer necessary to manually split it, thereby improving the work process and reducing the labor intensity of the operator. At the same time, the two threaded rods are threadedly connected with the two threaded holes, and then the upper mold is positioned, so as to avoid deviation when the upper mold is combined with the lower mold, thereby ensuring the accuracy of the gear after forming, and reducing the occurrence of defective products, thereby reducing the waste of raw materials and improving the output yield.

[0019] 5. The temperature control device for the bevel gear production mold is equipped with an electric telescopic rod. When the upper mold and the lower mold are separated, the electric telescopic rod is started, and the electric telescopic rod pushes the push plate upward, so that the formed gear is separated from the inside of the lower molding cavity, making it more convenient and quick to take out the gear.

[0020] 6. The temperature control device for the bevel gear production mold has a positioning rod and a telescopic plate. When it is necessary to cast a gear with an axial hole, the positioning rod can be inserted into the interior of the built-in groove, and the fixing rod is inserted into the interior of the auxiliary groove to complete the fixation of the positioning rod. The positioning rod forms an axial hole for the cast gear. When casting a gear without an axial hole, the fixing rod is disengaged from the built-in groove, and the spring inside the built-in groove releases the thrust to push the telescopic plate upward, so that the telescopic plate and the inner wall of the lower molding cavity are flush with each other, thereby completing the closure of the built-in groove, and making the bottom of the cast gear flat. When it is necessary to produce gears with or without axial holes, it is no longer necessary to replace the mold, thereby reducing the labor intensity of the operator, while improving the applicability and diversity of the device, thereby improving work efficiency, and reducing the time wasted in opening axial holes for gears in the later stage.

[0032] The lower molding cavity 201 is slidably connected with a push plate 205, and the push plate 205 is provided with a temperature sensor 209 and a detector 210. The temperature sensor 209 and the detector 210 are both connected with the display screen 5 for signal transmission.

The electric telescopic rod 204 is an existing structure and will not be described in detail here.

[0035] Working principle: When the temperature control device for bevel gear production mold is in use;

[0036] Step 1: Through the vacuum tube 301, when the bevel gear needs to be injection molded, the liquid can be poured into the upper molding cavity 304 and the lower molding cavity 201 through the vacuum tube 301, and an external vacuum extractor can be connected to the vacuum tube 301 to extract the air inside the upper molding cavity 304 and the lower molding cavity 201, thereby reducing the bubbles inside the bevel gear after molding, thereby improving the firmness of the gear after molding and the stability during use, and at the same time improving the production yield;

[0037] Step 2: When the gears inside the upper molding cavity 304 and the lower molding cavity 201 need to be heated and cooled again, the operation keyboard 6 is used to control the start of the heating tube 8 and the condenser 10 to ensure the molding effect and avoid the breakage caused by uneven condensation. At the same time, the start of the condenser 10 can accelerate the molding of the gears and play a cooling effect, thereby increasing the molding speed of the gears and improving the production efficiency. The heating tube 8 and the condenser 10 are cross-set, so that the temperature contacted by the gears during heating and cooling is more uniform, thereby ensuring the molding effect of the gears and reducing the occurrence of defective products, thereby reducing the waste of raw materials and reducing the cost. The card block 9 is movably connected to the inside of the card slot 7, so as to facilitate the maintenance and replacement of the heating tube 8 and the condenser 10. At the same time, the blocking of the card block 9 to the card slot 7 can effectively prevent dust and foreign matter from entering the inside of the card slot 7 to damage the heating tube 8 and the condenser 10, thereby increasing the service life of the heating tube 8 and the condenser 10 and reducing the cost of replacement and maintenance.

[0038] Step 3: By setting the motor 102, when the gear needs to be taken out after forming, the motor 102 is started, and the output end of the motor 102 rotates, thereby driving the first gear 103 to rotate, and the rotation of the first gear 103 causes the chain 101 to drive the second gear 208 to rotate, and then the second gear 208 drives the threaded rod 202 to rotate, and then the rotation of the threaded rod 202 causes the upper mold 3 to move upward, thereby separating the upper mold 3 from the lower mold 2, and then completely separating the upper mold 3 from the lower mold 2, thereby facilitating the removal of the gear, and no longer requiring manual disassembly, thereby improving the work process and reducing the labor intensity of the operator, and at the same time, the two threaded rods 202 are threadedly connected with the two threaded holes 303, thereby positioning the upper mold 3, thereby avoiding deviation when the upper mold 3 is combined with the lower mold 2, thereby ensuring the accuracy of the gear after forming, while reducing the occurrence of defective products, thereby reducing the waste of raw materials and improving the output yield;

[0039] Step 4: The temperature sensor 209 and the detector 210 can be used to observe and detect the temperature and molding conditions of the gears in the upper molding cavity 304 and the lower molding cavity 201, so that the operator can judge whether the gear needs to be heated again and cooled quickly through the data, so as to ensure that the produced gear meets the requirements. At the same time, the actual detection and observation can reduce the occurrence of defective products, so as to improve the output yield. The electric telescopic rod 204 is set, and when the upper mold 3 and the lower mold 2 are separated, the electric telescopic rod 204 is started, and the electric telescopic rod 204 pushes the push plate 205 upward, so that the molded gear is separated from the lower molding cavity 201, so that the gear can be taken out more conveniently and quickly.

[0040] Step 5: By setting the positioning rod 206 and the telescopic plate 213, when it is necessary to cast a gear with an axial hole, the positioning rod 206 can be inserted into the interior of the second built-in groove 211, and the fixing rod 214 is inserted into the interior of the auxiliary groove 216, so as to complete the fixing of the positioning rod 206, and the positioning rod 206 forms an axial hole for the cast gear. When casting a gear without an axial hole, the positioning rod 206 is separated from the second built-in groove 211, and the spring 212 in the second built-in groove 211 is released. The thrust is released to push the telescopic plate 213 upward, so that the telescopic plate 213 is flush with the inner wall of the lower molding cavity 201, thereby completing the closure of the built-in groove 211, and making the bottom of the cast gear flat. When it is necessary to produce gears with or without shaft holes, it is no longer necessary to replace the mold, thereby reducing the labor intensity of the operator, while improving the applicability and diversity of the device, thereby improving work efficiency, and reducing the time wasted in opening shaft holes for the gears in the later stage.
