Description

Technical Field

[0001] The invention relates to the technical field of casting moulds, in particular to an intelligent temperature-controlled casting mould. Background Art

[0002] A casting mold refers to a solid material formed by pouring molten metal or plastic into the mold and then cooling it. After pouring, the casting mold is usually cooled by self-cooling or liquid cooling contact. This type of cooling method cannot accurately adapt to the complex requirements of different casting materials for mold temperature under different casting processes. Direct contact with liquid cooling will also result in the internal material not being able to be compensated for shrinkage, causing casting defects such as shrinkage cavities and shrinkage, making it impossible for small castings to be formed normally.

[0003] The utility model with announcement number CN217617603U discloses a casting mold for preventing casting defects. By adding a centrifugal force mechanism, a rotating mechanism is provided. The rotating mechanism drives the casting mold to rotate at high speed. When casting the casting, liquid metal is injected from the straight runner of the mold. Under the die-casting effect of the centrifugal force generated by the high-speed rotation, the liquid metal can be cooled and solidified in the state of filling the cavity, so that the cavity of the casting is quickly filled and the casting is quickly formed. Due to the die-casting effect of the centrifugal force on the liquid metal, the casting can be fully compensated for shrinkage and the internal structure of the casting is denser.

[0004] The utility model with announcement number CN217595831U discloses a casting mold for elevator pulley production. When the casting cavity needs to be cooled, circulating cold water can be input into the main cylinder and the auxiliary cylinder respectively. The circulating cold water will flow through the outside of the casting cavity, so as to take away the heat near the casting cavity formed by the lower mold base and the upper mold base, and quickly cool it down. Therefore, when the temperature control treatment of the casting mold is carried out, the forming cavity area inside the casting mold can be quickly cooled down, thereby shortening the temperature control time and being more convenient to use.

[0005] However, the above-mentioned temperature-controlled casting mold still has the following problems during actual use: although cooling is achieved by injecting water into the mold, before the casting mold is cast, the mold at room temperature is in contact with the molten material, which will cause material defects due to the large temperature difference and also affect the service life of the mold. At the same time, the cooling liquid cannot be effectively controlled during the molding process, and rapid cooling can easily cause cracks in the internal material, affecting the molding accuracy.

[0006] Therefore, we proposed an intelligent temperature-controlled casting mold to solve the above problems. Summary of the invention

[0007] The purpose of the present invention is to provide an intelligent temperature-controlled casting mold. In order to solve the problem that the existing temperature control method is to use water injection in the mold to achieve cooling, but before the casting mold is cast, the mold at room temperature contacts with the molten material, which will cause material defects due to the large temperature difference and also affect the service life of the mold. At the same time, the cooling liquid cannot be effectively controlled during the molding process, and rapid cooling can easily cause cracks in the internal material, affecting the molding accuracy.

[0008] To achieve the above object, the present invention provides the following technical solution: an intelligent temperature-controlled casting mold, comprising a bearing base, and supporting columns fixedly installed at the four corners of the top surface of the bearing base, and a protective top plate is fixedly arranged on the top of the supporting columns;

[0011] Preferably, the left and right sides of the top surface of the supporting base are fixedly connected to the bottom end of the lifting side plates, and the top ends of the left and right lifting side plates are fixedly connected to the outer ends of the upper mold body, and the interiors of the symmetrically arranged lifting side plates are provided with through slide grooves, and the interiors of the through slide grooves are fixedly provided with positioning brackets.

[0012] Preferably, a guide gear is rotatably arranged inside the symmetrically arranged lifting side plates and passes through the upper end of the positioning bracket via a bearing, and guide racks are fixedly arranged on the outer sides of the upper ends of the left and right lifting side plates, and the guide racks are meshingly connected with the guide gears.

[0013] Preferably, a driving shaft is rotatably arranged below the symmetrically arranged positioning bracket through a bearing, and the outer end of the driving shaft is meshed and connected with the shaft of the guide gear through a first sprocket mechanism, and the guide rack is driven down by the lifting side plate, so that the meshing guide gear and the driving shaft rotate.

[0014] Preferably, the cooling mechanism includes a closed partition, and the closed partition is fixedly installed at the inner center position of the cooling frame, and a cooling circulation pipe is fixedly arranged between the closed partition and the cooling frame, and a lower mold body is fixedly arranged inside the closed partition, so that cooling of the lower mold body can be achieved through the cooling mechanism.

[0015] Preferably, the cooling mechanism includes a storage water tank, and the storage water tank is connected to the outer end of the cooling circulation pipe through a conveying pipe, and the cooling circulation pipe is arranged in a through connection distributed up and down, and a temperature control module is installed on the top surface of the storage water tank to adjust the cooling mechanism to work.

[0016] Preferably, the preheating mechanism includes a transmission shaft, and the transmission shaft is rotatably arranged on the upper and lower sides of the preheating frame through bearings, and the middle part of the lower transmission shaft is meshedly connected to the inner end of the driving shaft inside the lifting side plate through a bevel gear group.

[0017] Preferably, the preheating mechanism includes a transmission shaft, and the transmission shaft is rotatably arranged on the upper and lower sides of the preheating frame through bearings, and the middle part of the lower transmission shaft is meshedly connected to the inner end of the driving shaft inside the lifting side plate through a bevel gear group.

[0018] Preferably, the front end of the upper transmission shaft included in the preheating mechanism is fixedly connected to the shaft of the upper driving gear, so that the rotation directions of the upper and lower transmission shafts are arranged in opposite directions, and the middle outer walls of the upper and lower transmission shafts are fixedly connected to the outer ends of the preheating flip plates, and preheating nozzles are fixedly arranged at equal distances on the outer sides of the symmetrically arranged preheating flip plates.

[0019] Preferably, the preheating flip plates included in the preheating mechanism are distributed in an inner-outer staggered manner, and the preheating flip plates in the initial state are covered on the inner sides of the upper mold body and the lower mold body through the preheating nozzle, so that the preheating flip plates on the upper and lower sides can be flipped outwards for storage through the descent of the upper mold body to prevent affecting subsequent casting work.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: in the process of merging the upper mold body and the lower mold body, the preheating mechanism is turned over to heat the mold cavities on the upper and lower sides, thereby avoiding the large temperature difference with the material affecting the service life. At the same time, the temperature control module separates the cooling circulation pipe from the lower mold body through the closed partition of the cooling mechanism, thereby avoiding cracks caused by rapid cooling, and improving the casting molding precision and temperature control effect.

[0022] 2. The driving shaft rotates the transmission shaft of the preheating mechanism through the bevel gear group, and the second sprocket mechanism drives the driving gear and the upper transmission shaft to rotate. The transmission shafts distributed on the upper and lower sides drive the preheating flip plate to rotate outward in opposite directions, and heat the cavities of the upper mold body and the lower mold body during the rotation process to reduce the temperature difference between the molten material and the upper mold body and the lower mold body, thereby avoiding difficulty in demolding later.

[0023] 3. The combined upper mold body and lower mold body are cast and formed for the material through the mold cavity. At the same time, the temperature control module detects the temperature of the casting environment and drives the storage water tank of the cooling mechanism to inject water into the cooling circulation pipe inside the cooling frame, thereby realizing autonomous temperature control and heat dissipation assisted molding.

[0024] Furthermore, the cooling frame isolates the cooling circulation pipe from the lower mold body through an internal closed partition, so that the cooling circulation pipe can assist the material in cooling and solidification by wrapping it, so as to improve the accuracy of casting and improve the temperature control effect during the casting process.
