Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of molds, in particular to a slider structure mold capable of preventing demolding. BACKGROUND

[0002] The slider structure mold is a mold with a movable lateral forming component, which is mainly used for forming side holes, reverse buckles, threads and other features on the product that cannot be demolded through the conventional mold opening direction. The core feature is to complete the lateral parting or core-pulling action during mold opening or closing by driving the slider to move horizontally through inclined guide pillars, hydraulic cylinders or motors.

[0003] In the prior art, it is difficult to temporarily limit the degree of freedom of the plastic part during mold opening to ensure that the plastic part remains in the predetermined mold cavity. Demolding failure may occur due to reverse buckling, side hole structure, etc.

[0004] In addition, in the prior art, it is difficult to real-time scan the distance between the top of the slider and the upper mold, thereby it is difficult to ensure the uniformity of the closed gap between the slider and the upper mold, and the phenomenon of flash or size deviation caused by misalignment may occur. It is also difficult to monitor the temperature at the bottom of the upper film, which increases the product shrinkage or deformation caused by local overheating. High-speed movement will increase the instantaneous impact force between the slider and the guide rail, accelerate the wear of key components such as guide grooves and inclined guide pillars, and the high-speed inertia is easy to cause the slider to rebound or overshoot after reaching the position, affecting the forming precision of the reverse buckling structure. The prior art is difficult to reduce the moving speed of the slider, and the practicality is relatively single.

[0005] Finally, the local temperature may reach above 150℃ during high-speed movement, and micro-welding may occur on the metal surface. The continuous sliding of the slider and the guide rail will cause the material to gradually wear and the gap to increase. The prior art is difficult to spray lubricating oil on the slider and capture the wear condition of the slider surface through a camera, and the practicality is relatively single. SUMMARY

[0038] First, when using the device, place the device in the working area, then connect the device with the external power supply, and the device can provide the power required for work;

[0039] Second, when the lower mold 1 and the upper mold 5 are combined to perform injection molding, the product is cooled by external equipment, and before the sliding block 41 starts to core, two groups of first motors 36 are started synchronously, the directions of rotation of the two groups of first motors 36 are opposite, the two groups of first motors 36 drive the two groups of cams 35 to rotate, and in the rotating process of the cams 35, the arc-shaped sliding grooves 34 at the top of the cams 35 slide with the first protruding rods 33 at the end of the moving blocks 32, because the water drop-shaped arc-shaped sliding grooves 34 are arranged, the two groups of first protruding rods 33 slide from the near center end to the far center end in the movement process, the distance between the two groups of first protruding rods 33 gradually changes from the farthest distance to the shortest distance, and the distance between the two groups of first protruding rods 33 can also gradually change from the shortest distance to the farthest distance, then the two groups of first protruding rods 33 drive the distance between the two groups of suction cups 31 to gradually shorten, when the two groups of suction cups 31 contact the product, the two groups of suction cups 31 extrude the side of the product to make the airflow in the suction cups 31 flow out, and the suction cups 31 generate suction force to adsorb the product, after the adsorption is completed, the mold is opened, the suction cups 31 release the vacuum, and the product is ejected by the ejector in the lower mold 1, so that the product is fixed by the suction cups 31, the freedom of the product is temporarily limited in the opening process, the product is ensured to stay in the predetermined mold cavity, and the demolding failure caused by structures such as reverse buckling and side hole is prevented.

[0040] Embodiment two:

[0046] Second, when the upper mold 5 is moving, the heat of the upper mold 5 is first transmitted to the ceramic layer 47 through direct contact, the ceramic layer 47 acts as an intermediate medium for heat transfer, and at the same time, the electrical conduction between the upper mold 5 and the top pin 44 is blocked to avoid interference with the thermocouple signal, then the small gap between the ceramic layer 47 and the top pin 44 is filled with the heat-conducting silicone layer 46 to reduce air insulation and significantly improve the heat transfer efficiency, so that the heat of the ceramic layer 47 is quickly transmitted to the top pin 44, thereby making the top pin 44 a "thermal conductor", and then the heat is transmitted to the thermocouple wire 45 welding point on the surface of the top pin 44, and the temperature of the top pin 44 is converted into an electrical signal by using the thermoelectric effect of the thermocouple, thereby realizing indirect detection of the temperature at the bottom of the upper mold 5 and reducing product shrinkage or deformation caused by local overheating.
