The invention discloses a demolding device for injection molding production of daily necessities and a using method thereof, and relates to the technical field of injection molding production. The demolding device for injection molding production of the daily necessities and the using method thereof aim to solve the problems that an existing demolding device is complex in structure and inconvenient to demold, and damage is caused due to the fact that the situation of uneven stress is prone to occurring during demolding. A lower mold base is installed at the upper end of a bottom plate; an upper mold base is arranged below a top plate; an injection molding cavity is formed between the lower mold base and the upper mold base; a daily necessity injection molding part is arranged inside the injection molding cavity; inclined bolts are arranged on the two sides of the lower end of the upper mold base; side demolding mechanisms are arranged on the two sides of the upper end of the lower moldbase; inclined guide holes are formed in the two sides of the upper end of each side demolding mechanism; grooves are formed in the inner sides of the side demolding mechanisms; first springs are installed inside the grooves; one end of each first spring is fixedly connected with the corresponding groove, and the other end of each first spring is fixedly connected with the lower mold base; and the lower mold base is slidably connected with the side demolding mechanisms.

The invention discloses a conveying device. The device is used for loading, conveying and releasing an implant; and the conveying device comprises a handle, an inner core tube, a sheath tube and a guide head, the near end of the inner core tube is connected with an inner core tube movable part in the handle, and the guide head arranged at the far end of the inner core tube is fixedly connected with the far end of the sheath tube, wherein the near end refers to one end close to the handle, and the far end refers to one end far away from the handle. In the device, the far end of the sheath tubeis fixedly connected with the guide head, so that the conveying device can only load the implant through the near end of the sheath tube, when the implant is released, the sheath tube should move to the far end, that is, the sheath tube continues moving forward to the target position of the implant, instead of retreating towards the handle, so that problems such as unstable or even wrong implant release caused by retreating through a three-dimensional curved path of a sheath tube can be effectively avoided, and the release quality of the implant can be improved.

The invention provides a column re-attachment demolding device. The column re-attachment demolding device comprises an outer supporting frame (1), an inner supporting frame (2), a transmission mechanism (3) and hangers (4). The inner supporting frame (2) is embedded into the outer supporting frame (1), and the inner supporting frame (2) is connected with the outer supporting frame (1) through thetransmission mechanism (3). The inner supporting frame (2) comprises multiple cross columns, the cross columns are horizontally arranged and arrayed, and the included angle between every two adjacentcross columns is identical. The hangers (4) are arranged at the ends of the cross columns, each cross column is correspondingly provided with one hanger (4), and the hangers (4) and the ends of the cross columns are detachably locked. The transmission mechanism (3) is used for driving the inner supporting frame (2) and the hangers (4) to rise or fall in the vertical direction. By means of the device, it can be guaranteed that in the demolding process, a packaging device is evenly stressed, the demolding quality after column re-attachment is improved, and the success rate after column re-attachment is increased.

The invention relates to the technical field of injection molds, and discloses an injection mold, which includes a hydraulic device, a hydraulic rod movable mold and a fixed mold, and the hydraulic device and the movable mold are connected through a hydraulic rod to form a The mold cavity is equipped with a cooling water channel, and the middle part of the fixed mold is provided with a pouring port. The pouring port is connected with the cavity and the pouring port is connected with the injection molding machine. The action of the iron drives the seal to move down, so that a gradual negative pressure is formed between the seal and the movable mold. The gradual negative pressure acts on the injection molded part, which can ensure that the outer wall of the injection molded part and the inner wall of the fixed mold They can be slowly separated from each other, so that the bonding resistance between them disappears, and they are separated from the fixed mold while the movable mold moves downward. From the perspective of the demoulding process, when the injection molded part is demoulding, its surface and the fixed mold are separated. The mold is not bonded, and the resistance is relatively small, which improves the surface quality of injection molded parts when they are demolded.

The invention relates to the technical field of pouring molds with self-cooling function, in particular to a pouring mold with self-cooling function, including a supporting structure, a first pouring structure, a driving structure, a second pouring structure, and a transmission structure , the first demoulding structure and the second demoulding structure; it is convenient to drive the second casting structure to rotate 90 degrees through the driving structure while lifting, so as to make the second casting structure face the operator, thereby greatly improving Improve the efficiency and quality of the inspection and maintenance of the second casting structure, and then facilitate the drive structure to drive the transmission structure, so that the transmission structure drives the first casting structure to rotate, thereby greatly improving the efficiency and quality of the inspection and maintenance of the first casting structure Quality: it is convenient to use the drive structure to drive the second pouring structure to rotate, so that the first demoulding structure is in contact with the supporting structure, so that the first demoulding structure can quickly demould the workpiece inside the second pouring structure.

The invention relates to a three-dimensional space curved face steel-mould trolley demoulding anti-interference device and method. Through longitudinal rotary shafts arranged on the tops of side moulds and the lower portions of a top mould, side mould action oil cylinders at the bottoms of the side moulds contract, the side moulds are rotated towards the inner side with the longitudinal rotary shafts as the axis, and demoulding of a three-dimensional space curved face steel-mould trolley at the bend section can be achieved successfully. The problem that as the boundaries of the top mould and the side moulds are space folding lines due to limitation of the three-dimensional space structural shape, the side moulds cannot contract transversely for demoulding through conventional arrangement is solved. The demoulding quality is high, templates will not twist or deform, the templates will not intervene in lined concrete, and construction safety is guaranteed.

The present invention provides a multifunctional cable retracting device and its control method, comprising: a base, multiple mounting frames, two winding mechanisms and a first power mechanism, and multiple mounting frames are fixed on the top surface of the base , the winding mechanism is rotatably arranged between two adjacent installation frames. In the multi-functional cable retracting device of the present invention, the two winding drums rotate in opposite directions at the same time, which facilitates the replacement of worn-out and aging cables in the project with new ones, instead of the traditional need to perform two consecutive operations successively, saving energy. Time and convenient operation, reduce labor intensity; improve the flexibility of use, adapt to a variety of construction scenarios; avoid two cables intertwined with each other, ensure smooth operation, improve the quality of new cables, and extend the service life of new cables ; Only one double-axis motor is used, saving production cost and working electric energy.
