Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to a shot-moving device and an injection molding machine. Background Art

[0002] Injection molding machine is an important equipment used to manufacture plastic products. It injects molten plastic into the mold through heating and high pressure, and forms the plastic product of the desired shape after cooling.

[0003] In related technologies, the injection molding machine's shot-shifting mechanism moves the shooting platform, bringing the nozzle into contact with the mold and establishing a supporting force to prevent plastic overflow during the injection molding process. To accommodate the movement of the shooting platform, a space is often required, which reduces the available space for other components of the injection molding machine. Furthermore, to accommodate the movement of the shooting platform, auxiliary devices require more parts and longer cable runs, making the injection molding machine structure complex and the internal wiring messy. This not only makes it prone to mechanical interference and potential risks, but also increases the response time of the machine's actions, affecting efficiency.

[0004] Therefore, it is necessary to develop a new type of injection molding device and injection molding machine to improve some of the above problems existing in the relevant technology. Utility Model Content

[0005] The purpose of the utility model is to provide a shot-shifting device and an injection molding machine, which can optimize the structure of the injection molding machine, save internal space, reduce the response time of mechanical action, and improve efficiency and safety.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] The utility model provides a shooting and moving device, comprising: a shooting platform mechanism, a driving mechanism, and a power mechanism; the driving mechanism is connected to the shooting platform mechanism and is used to drive the shooting platform to move; the power mechanism is used to provide power to the driving mechanism; wherein, the shooting platform mechanism comprises a shooting platform body and a moving component, and the shooting platform body and the power mechanism can be movably arranged on the moving component.

[0008] Optionally, the driving mechanism includes a connecting rod, which connects the fixed template and the shooting platform body.

[0009] Optionally, at least two connecting rods are arranged oppositely on two sides of the shooting platform body.

[0010] Optionally, the power mechanism is a hydraulic power system.

[0011] Optionally, the power mechanism includes a hydraulic pump, and the hydraulic pump is arranged on a side of the shooting platform body away from the fixed template.

[0012] Optionally, the hydraulic pump is driven by a motor, and the driver of the motor is integrated into the housing of the motor.

[0013] Optionally, the driving mechanism further includes a hydraulic cylinder, which is disposed on the moving component.

[0014] Optionally, the shooting and displacement device further includes a transmission mechanism, the transmission mechanism includes a valve block, and the power mechanism is connected to the shooting platform body via the valve block.

[0015] Optionally, the transmission mechanism further includes a hydraulic pipeline, which connects the valve block and the power mechanism.

[0016] The utility model also provides an injection molding machine, comprising the above-mentioned injection-shifting device.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The utility model arranges the power mechanism and the shooting platform body on the mobile assembly. When the power mechanism provides power to the driving mechanism, the driving mechanism not only drives the shooting platform body to move, but also drives the power mechanism to move along with the shooting platform body. In this way, the position setting of the power mechanism utilizes the installation space and moving space of the shooting platform mechanism, realizes the integration of the shooting platform body and the power mechanism, optimizes the structure, and effectively saves the internal space of the injection molding machine.

[0019] 2. The present invention integrates the shooting platform body and the power mechanism into one, so that the power mechanism moves along with the shooting platform body during its movement, and the relative position between the two does not change. This allows the transmission mechanism connecting the shooting platform body and the power mechanism to be connected without requiring a reserved length, such as a pipeline for transmitting hydraulic oil. This helps to shorten the length of the actual oil circuit, reduce the response time of the mechanical action, and improve efficiency.

[0020] 3. The utility model further reduces the space occupied by the power mechanism by integrating the driver of the motor in the power mechanism into the interior of the motor, and arranges the hydraulic pump and the motor adjacent to each other and connects them to the main body of the shooting platform through the valve block, so that the motor line, valve head line, etc. are all concentrated together. All lines only need to reserve one pipeline passage, making the wiring simpler, reducing the risk of mechanical interference in the line pipeline, and improving safety.
