Description

Technical Field

[0001] The utility model relates to the technical field of hot runner plastic molds, in particular to an integrated hot runner plastic mold. Background Art

[0002] The hot runner system is generally composed of several parts such as hot nozzles, manifolds, temperature control boxes and accessories. Hot nozzles generally include two types: open hot nozzles and needle valve hot nozzles. Since the form of hot nozzles directly determines the selection of hot runner systems and the manufacture of molds, the hot runner system is often divided into open hot runner systems and needle valve hot runner systems accordingly. The manifold is used when there are multiple cavities in one mold or multi-point feeding, or single-point feeding but the material level is offset. The material is usually P20 or H13. Manifolds are generally divided into two categories: standard and non-standard. Their structural form is mainly determined by the distribution of cavities on the mold, nozzle arrangement and gate position. The temperature control box includes the main machine, cables, connectors and wiring male and female sockets. Hot runner accessories usually include: heaters and thermocouples, runner sealing rings, connectors and junction boxes, etc., but now hot runner plastic molds are connected to the mounting seat with screws, which requires tools to remove the screws one by one when they need to be replaced, resulting in slow replacement. For this reason, we propose an integrated hot runner plastic mold. Utility Model Content

[0003] The purpose of the utility model is to provide an integrated hot runner plastic mold, which has the advantage of quick replacement and solves the problem that the current hot runner plastic molds are connected to the mounting base with screws, resulting in the need to use tools to remove the screws one by one when replacement is needed, resulting in slow replacement speed.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an integrated hot runner plastic mold, comprising a base and a mold body, grooves are provided at both left and right ends of the bottom of the mold body, a slot is provided on the side of the inner cavity of the groove, an installation groove is provided on the top of the base, a double-headed motor is fixedly connected to the middle end of the bottom of the inner cavity of the installation groove, the output shaft of the double-headed motor is fixedly connected to a threaded rod, the outer surface of the threaded rod is threadedly connected to a threaded tube, the other end of the threaded tube is fixedly connected to a movable plate, a pressure sensor is arranged between the movable plate and the threaded tube, an insert is fixedly connected to the upper part of the side of the movable plate, and the insert is movably connected to the inner cavity of the slot.

[0005] Preferably, both front and rear ends of the left and right sides of the base are fixedly connected with fixing blocks, and bolts are provided on the fixing blocks.

[0006] Preferably, positioning grooves are provided at both left and right ends of the top of the base, and positioning blocks are fixedly connected to both left and right ends of the bottom of the mold body, and the positioning blocks are slidably connected to the inner cavity of the positioning grooves.

[0007] Preferably, a tool box is fixedly connected to the back side of the base, a partition is fixedly connected to the inner cavity of the tool box, and a box door is provided on the tool box.

[0008] Preferably, guide grooves are provided at both left and right ends of the bottom of the inner cavity of the installation groove, and a guide block is fixedly connected to the bottom of the threaded tube, and the guide block is movably connected to the inner cavity of the guide groove.

[0009] Preferably, a display is fixedly connected to the right end of the front side of the base, and an input end of the display is electrically connected to an output end of the pressure sensor.

[0010] Preferably, a PLC controller is fixedly connected to the left end of the front side of the base, and the output end of the PLC controller is electrically connected to the input end of the double-headed motor.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The utility model can play a positioning role through the positioning groove and the positioning block, which is convenient for people to determine the position when installing the mold body. The double-headed motor can be used to drive the threaded rod to rotate, and with the cooperation of the guide block and the guide groove, the threaded tube can be moved left and right. When the double-headed motor rotates forward, the threaded tube will move in the direction away from the double-headed motor, thereby driving the movable plate to move right, allowing the plug block to enter the slot, thereby playing a fixing role. The pressure sensor can be used to detect the pressure between the movable plate and the threaded tube. When the plug block completely enters the slot, the value of the pressure sensor will increase, which is convenient for people to stop the double-headed motor in time. When disassembly is required, the double-headed motor is controlled to reverse, so that the plug block leaves the slot, which is convenient for people to quickly replace it. It solves the problem that the current hot runner plastic molds are all connected to the mounting seat with screws, resulting in the need to use tools to remove the screws one by one when replacement is required, resulting in slow replacement speed.
