Description

Technical Field

[0001] This utility model belongs to the technical field of mold opening devices, and specifically relates to a mold opening device for an interference fit mold. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping.

[0003] While existing mold-opening devices can meet the basic requirements of opening interference-fit molds and separating the upper and lower molds, current devices rely on manual mold opening using a V-shaped chisel and hammers of varying sizes. One person holds the chisel while another swings the hammer, using the V-angle of the chisel to generate lateral force, forcing the interference-fit upper mold (male mold) and lower mold (female mold) apart. During the hammering of the chisel, metal impacts easily generate flying metal shavings that can injure workers, and the noise generated is extremely loud. Furthermore, operator error during the process can easily lead to hand injuries and other workplace accidents. In summary, this manual mold-opening method suffers from high labor intensity, low efficiency, and significant safety risks. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a mold opening device for an interference fit mold, which not only meets the basic requirements for mold opening, but also features convenient operation, high processing efficiency, and high safety.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a mold opening device for an interference fit mold, including a fixed bracket, a sliding trolley slidably disposed at the bottom of the fixed bracket, a mold rotatably disposed on the sliding trolley, a first telescopic push rod disposed at the top of the fixed bracket, a mounting bracket disposed at the lower end of the output shaft of the first telescopic push rod, and a mold opening cutter for opening the mold rotatably disposed in the mounting bracket. The vertical cross-section of the mold opening cutter is rhomboid. The V-shaped mold opening cutter is suitable for molds of various shapes, especially interference fit molds.

[0006] As a further improvement of this utility model, a second telescopic push rod is provided on one side of the bottom of the fixed bracket. The output shaft of the second telescopic push rod is connected to the sliding trolley, and the bottom of the sliding trolley is slidably connected to the bottom of the fixed bracket.

[0007] As a further improvement of this utility model, the sliding trolley is rotatably equipped with a transmission roller track for supporting and rotating the mold. The transmission roller track has a receiving groove for accommodating the mold. The axial length of the receiving groove is greater than the axial length of the mold. The transmission roller tracks are rotatably connected by chains and sprockets.

[0008] As a further improvement of this utility model, a drive motor is provided on the placement frame, and the drive motor is rotatably connected to a transmission roller conveyor through a gear transmission assembly.

[0009] As a further improvement of this utility model, the vertical cross-section of the mold-opening tool is rhomboid.

[0010] As a further improvement of this utility model, the mold-opening tool is rotatably connected to the mounting bracket. This can prevent the mold-opening tool from being easily damaged.

[0011] As a further improvement of this utility model, the first telescopic push rod is a hydraulic telescopic rod. It can effectively drive the mold opening tool, resulting in more significant mold opening.

[0012] As a further improvement of this utility model, the side end of the mounting bracket is also provided with a guide plate that is vertically slidably connected to the side end of the fixed bracket. The guide plate is provided with a guide hole that is slidably connected to the side end of the fixed bracket. Through the cooperation of the guide plate and the guide hole, the mold opening tool can move vertically stably and avoid the mold opening tool from easily deviating during operation, and also prevent the first telescopic push rod from being easily damaged by non-vertical forces.

[0013] As a further improvement of this utility model, a clamping roller is also rotatably mounted on the mounting bracket to limit the mold's position. The clamping roller prevents the mold from shifting vertically, ensuring the mold remains stable during the mold opening process.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] Firstly, the sliding trolley is driven by the second telescopic push rod to achieve precise positioning of the mold on the fixed support; the first telescopic push rod (hydraulic telescopic rod) drives the V-shaped mold opening cutter to move up and down to complete the mold opening action.

[0016] Secondly, by accommodating the groove, the mold can be prevented from sliding directly off the transmission roller. Furthermore, because the axial length of the accommodating groove is greater than the axial length of the mold, space can be provided for the mold to move after it is opened and separated.

[0017] Third, the drive motor provides rotational driving force to the transmission roller conveyor through the gear transmission assembly. Attached Figure Description

Detailed Implementation

[0023] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0024] like Figure 1 , 2 As shown, a mold opening device for an interference fit mold includes a fixed bracket 101. A sliding carriage 102 is mounted on the bottom of the fixed bracket 101. The mold 100 is rotatably mounted on the sliding carriage 102. A first telescopic push rod 103 is mounted on the top of the fixed bracket 101. A mounting bracket 104 is mounted on the lower end of the output shaft of the first telescopic push rod 103. A mold opening cutter 105 for opening the mold 100 is rotatably mounted in the mounting bracket 104. The mold opening cutter 105 has a rhomboid vertical cross-section. The V-shaped mold opening cutter 105 is suitable for molds 100 of various shapes, especially interference fit molds 100. The first telescopic push rod 103 is a hydraulic telescopic rod.

[0025] A position sensor is also provided on the side of the fixed bracket 101. The position sensor includes a signal transmitter on one side of the fixed bracket 101 and a signal receiver on the other side of the fixed bracket 101. When the signal receiver receives a signal that can be received by the signal transmitter, it means that the mounting bracket 104 has not moved between the signal transmitter and the signal receiver and has not blocked or hindered the signal transmission process between the signal transmitter and the signal receiver. When the signal receiver cannot receive a signal that can be received by the signal transmitter, it means that the mounting bracket 104 has not moved between the signal transmitter and the signal receiver and has not blocked or hindered the signal transmission process between the signal transmitter and the signal receiver. It means that the mounting bracket 104 and the mold cutting tool 105 have moved into position.

[0026] like Figure 1 , 2As shown, a second telescopic push rod 106 is provided on one side of the bottom of the fixed bracket 101. The output shaft of the second telescopic push rod 106 is connected to the sliding trolley 102. The bottom of the sliding trolley 102 is slidably connected to the bottom wall of the fixed bracket 101. A connecting groove 109 is provided at the bottom of the fixed bracket 101. A connecting slider 108 is fixedly connected to the bottom of the sliding trolley 102 and is fixedly connected to the connecting groove 109.

[0027] like Figure 1 , 2 As shown, a transmission roller conveyor 201 is rotatably mounted on the sliding trolley 102 to support and drive the rotation of the mold 100. The transmission roller conveyor 201 has a receiving groove for accommodating the mold 100, the axial length of which is greater than the axial length of the mold 100. The transmission roller conveyors 201 are rotatably connected by chains and sprockets. The transmission roller conveyor 201 supports the mold 100 and drives its rotation through friction during operation.

[0028] The user places the mold 100 to be opened into the receiving groove on the transmission roller 201 of the sliding trolley 102; and adjusts the position of the mold 100 on the transmission roller 201 to ensure that its opening part is directly aligned with the V-shaped mold opening cutter 105. Then, the user drives the sliding trolley 102 and the mold 100 to move to the lower side of the mold opening cutter 105, and then drives the output axis of the first telescopic push rod 103 to extend downward by a certain length until the mold opening cutter 105 is embedded into the mold 100 to a certain depth, thus creating a new opening between the upper and lower molds.

[0029] Since the sliding trolley 102 slides at the bottom of the fixed bracket 101, the mold 100 has good stability during the movement. Through the friction between the mold 100 and the transmission roller 201, the mold 100 can be prevented from easily shifting axially relative to the transmission track, so that the mold 100 maintains the position corresponding to the mold opening cutter 105.

[0030] Then the mold 100 can be driven to rotate relative to the sliding trolley 102. Under the pressing action of the mold opening cutter 105, the entire side of the mold 100 is opened along the initially opened mold opening opening.

[0031] During the mold opening process, after opening a hole in the mold 100, the mold 100 can be opened by directly rotating the mold 100 with the cooperation of the mold opening tool 105. Alternatively, after opening a hole, the mold opening tool 105 can be moved back a certain distance, and then the mold 100 can be rotated at a certain angle before opening another hole in the mold 100. After opening multiple holes in the mold 100 in the above manner, the mold 100 can be rotated and opened with the cooperation of the mold opening tool 105. This method makes it easier for the transmission roller 201 to rotate the mold 100 and to complete the mold opening process.

[0032] Then, the sliding trolley 102 and the mold 100 after mold opening are reset, and the mold 100 can be unloaded and loaded, and then the mold opening process can continue.

[0033] According to another embodiment of the present invention, a drive motor is provided on the placement frame, and the drive motor is rotatably connected to a transmission roller conveyor 201 via a gear transmission assembly.

[0034] By simply starting the drive motor, one transmission roller 201 can be driven to rotate via the gear transmission assembly, and under the drive of the transmission chain and transmission sprocket, both transmission rollers 201 will rotate. The rollers can support the rotating mold 100, preventing the mold 100 from being suspended in the air, and enabling the mold opening cutter 105 to stably open the mold 100.

[0035] According to another embodiment of the present invention, the vertical cross-section of the mold-opening tool 105 is rhomboid. The mold-opening tool 105 is rotatably connected to the mounting bracket 104, which can satisfy the mold-opening of the mold 100 while avoiding damage to the mold-opening tool 105 and extending the service life of the mold-opening tool 105.

[0036] According to another embodiment of the present invention, such as Figure 2 As shown, a clamping roller 107 for limiting the mold is also rotatably mounted on the mounting bracket 104. After the mold opening tool makes a cut in the mold, the clamping roller can press against the top of the lower mold and the upper mold, thereby effectively preventing the mold from shifting vertically and keeping the mold stable during the mold opening process.

[0037] According to another embodiment of the present invention, such as Figure 3As shown, the side end of the mounting bracket 104 is also provided with a guide plate 301 that is vertically slidably connected to the side end of the fixed bracket 101. The guide plate 301 has a guide hole that is slidably connected to the side end of the fixed bracket 101. The guide plate 301 can be vertically slidably connected to the side end of the fixed bracket 101 through the guide hole, thereby enabling the mounting bracket 104 and the mold-opening cutter 105 to move stably vertically, and preventing the mold-opening cutter 105 from easily deviating during operation, and preventing the first telescopic push rod 103 from being easily deformed and damaged by non-vertical forces.

[0038] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
