Description

Technical Field

[0001] This utility model relates to the field of brake disc mold technology, specifically a truck brake disc mold. Background Technology

[0002] Brake discs are the friction pairs of disc brakes. In addition to having the strength and rigidity required as components, they should also have the highest and most stable coefficient of friction, as well as appropriate wear resistance, heat resistance, heat dissipation and heat capacity. Truck brake disc molds are key equipment used for casting brake discs, and their performance directly affects the molding quality, production efficiency and product life of the brake discs.

[0003] Traditional brake disc molds suffer from the following technical problems: Insufficient cooling efficiency: Traditional molds mostly use natural cooling or simple water cooling, which can lead to uneven cooling and stress concentration inside the casting, resulting in deformation or cracks. Difficult demolding: The brake disc has a complex structure and is prone to sticking to the mold during demolding, requiring manual intervention, reducing production efficiency and potentially damaging the surface of the casting. Short mold life: High-temperature molten metal comes into direct contact with the mold surface, and the lack of effective temperature control and release agent spraying protection makes the mold prone to wear. To address these issues, we propose a new type of truck brake disc mold. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a truck brake disc mold. It adopts a rotating cooling coil on both sides to ensure that the casting is not prone to deformation and cracking. The sprayed release agent can improve the coating effect of the casting to ensure the service life of the mold, which is conducive to the production of truck brake discs and can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a truck brake disc mold, comprising a bottom mold and a top plate;

[0006] Bottom mold: The top surface of the bottom mold corresponds to and fits with the bottom surface of the top mold. The top surface of the bottom mold has grooves on both sides, and a fixing column is fixed inside the groove. The bottom surface of the bottom mold has through holes. The front and rear sides of the top plate are equipped with brackets. The top ends of the brackets on both sides are connected to the bottom surfaces of the corresponding two stripper plates. The top surface of the top plate is equipped with spring seats on both sides. The bottom end of the spring seat is correspondingly engaged with the bottom end of the spring. The top end of the spring is fitted and installed against the top surface inside the bottom mold. The left and right sides of the bottom mold are equipped with cooling units. The inside of the bottom mold is equipped with a spraying unit.

[0007] It also includes a controller, which is located on the front side of the bottom mold, and the input terminal of the controller is electrically connected to the output terminal of an external power supply.

[0008] An external hydraulic rod is used to push the top plate to raise the support frame. The two stripping plates at the top of the support frame can push the truck brake discs out of the disc groove, thus solving the problem of time-consuming and laborious manual stripping.

[0009] Furthermore, the cooling unit includes a fixed plate, cooling coils, a circulating pump, a coolant tank, a thermoelectric cooler, and a cooling trough. There are two cooling troughs, each located on one of the left or right sides of the bottom mold, and they are connected to each other. A cooling coil is fixed to the inner side of the fixed plate, and the cooling coil is located inside the cooling trough. The coolant tank is mounted on the surface of the fixed plate, and its inlet is connected to the outlet of the cooling coil. A circulating pump is mounted on the rear side of the coolant tank, and its outlet pipe is connected to the inlet of the cooling coil. The thermoelectric cooler is mounted on the surface of the coolant tank, and its cooling end is located inside the coolant tank. The input ends of the circulating pump and the thermoelectric cooler are electrically connected to the output end of the controller. The two cooling coils inserted into the cooling trough provide dual-sided cooling for the mold, effectively improving cooling efficiency. Combined with the thermoelectric cooler and the circulating pump, the coolant is circulated to achieve closed-loop forced cooling, thereby increasing the cooling speed.

[0010] Furthermore, the cooling unit also includes a main temperature sensor and a secondary temperature sensor. The main temperature sensor is mounted on the surface of the fixed plate, and the secondary temperature sensor is mounted on the top surface of the coolant tank. The output terminals of the main temperature sensor and the secondary temperature sensor are electrically connected to the input terminal of the controller. The main temperature sensor and the secondary temperature sensor monitor the temperature of the mold and the coolant in real time. The controller dynamically adjusts the cooling power to avoid overcooling or insufficient cooling and reduce thermal stress deformation of the casting.

[0011] Furthermore, the cooling unit also includes a screw and a sealing ring. The screw is rotatably installed in the shaft hole on the surface of the fixed plate, and the sealing ring is bonded to the surface of the bottom mold. The rotating screw facilitates the disassembly and assembly of the fixed plate for subsequent maintenance, while the sealing ring increases the sealing performance of the installation.

[0012] Furthermore, the spraying unit includes a spray head, an annular plate, slide bars, a liquid pump, and a release agent tank. The release agent tank is placed inside the bottom mold. A liquid pump is installed on the top surface of the release agent tank. The outlet pipe of the liquid pump is connected to the inlet of the spray head. The spray head is located inside the fixed column. Slide bars are fixed on both sides of the bottom surface of the annular plate. The bottom end of the slide bar passes through the groove on the surface of the tray and connects to the inside of the bracket. The annular plate is slidably connected to the outside of the fixed column. The input end of the liquid pump is electrically connected to the output end of the controller. The annular plate rises with the bracket to expose the spray head. The liquid pump is started to spray the release agent evenly inside the tray to reduce the risk of adhesion and improve the success rate of demolding.

[0013] Furthermore, the spraying unit also includes a liquid level sensor, which is installed on the front side of the release agent tank. The output of the liquid level sensor is electrically connected to the input of the controller. The liquid level sensor can provide early warning of the remaining release agent level to avoid production interruption.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This truck brake disc mold has the following advantages:

[0015] 1. The mold is cooled on both sides by two cooling coils inserted in the cooling tank, which can effectively improve the cooling efficiency. In addition, the coolant is circulated by a semiconductor cooler and a circulating pump to achieve closed-loop forced cooling and improve the cooling speed.

[0016] 2. The main and secondary temperature sensors are set to monitor the temperature of the mold and coolant in real time. The controller dynamically adjusts the cooling power to avoid overcooling or insufficient cooling and reduce thermal stress deformation of the casting.

[0017] 3. By using an external hydraulic rod to push the top plate and drive the support to rise, the two stripping plates at the top of the support can push out the truck brake disc inside the disc groove, thus solving the problem of time-consuming and laborious manual stripping. The ring plate rises with the support to expose the spray head, and the hydraulic pump is started to spray the release agent evenly inside the disc groove, thereby reducing the risk of adhesion and improving the success rate of demolding.
