Description

Technical Field

[0001] The utility model relates to the technical field of forming molds, in particular to a plug connector forming mold. Background Art

[0002] The engine solenoid valve is an actuator in the idle control system. It is mainly used to control or adjust the idle speed, ensure that the engine emissions meet the standards (requirements) and that the engine runs stably, and keep the engine idle speed at the lowest (within the specified range), thereby effectively reducing fuel consumption.

[0003] The engine solenoid valve needs a plug connector to connect to the power supply when in use. The plug connector is generally made by injection molding. After the common molding mold introduces the injection liquid into the plug connector molding cavity, it is usually directly cooled and formed, which makes it easy for bubbles to appear inside the plug connector after injection molding, affecting the quality of the plug connector. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a plug connector molding die, comprising a debubble mechanism, a molding groove, an upper die and a lower die, a molding groove is arranged at the central position of the top of the lower die, and plug connector molding cavities are opened on both sides of the molding groove, an upper die is arranged above the lower die, a debubble mechanism is arranged below the lower die, and a first rotating drive mechanism is arranged at the central position of the top of the debubble mechanism, an eccentric wheel is arranged at the output end of the first rotating drive mechanism through a roller, and the top of the eccentric wheel is in contact with the bottom of the lower die.

[0006] Preferably, spring cylinders are provided at the four corners of the top of the defoaming mechanism, and pressure columns are provided inside the spring cylinders through rigid springs, and the tops of the pressure columns are connected to the bottom of the lower mold.

[0007] Preferably, a screw rod is provided on one side of the lower mold through a frame, and a driving block is sleeved on the screw rod, and one end of the driving block is connected to the upper mold.

[0008] Preferably, a second rotation drive mechanism is fixed to the top of the frame, and an output end of the second rotation drive mechanism is connected to the screw rod.

[0009] Preferably, a guide sleeve is sleeved on the frame, and one end of the guide sleeve is connected to the driving block.

[0010] Preferably, positioning holes are provided at the four corners of the top of the lower mold, and positioning columns are provided at the four corners of the bottom of the upper mold.

[0011] Preferably, the positioning posts are all embedded in the positioning holes, and the bottom ends of the positioning posts are all provided with rubber pads.

[0012] Preferably, guide grooves are provided on both sides of the interior of the spring tube, and guide blocks matching the guide grooves are provided on both sides of the bottom of the pressure column.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The plug connector molding die is equipped with a defoaming mechanism, a lower mold, an upper mold, a molding groove, a plug connector molding cavity, a first rotating drive mechanism, and an eccentric wheel. After the injection liquid is injected into the plug connector molding cavity, the upper mold and the lower mold are merged. Then, the first rotating drive mechanism drives the eccentric wheel to rotate through a roller, and the eccentric wheel drives the lower mold to vibrate up and down, thereby automatically discharging the gas in the plug connector molding cavity, realizing the defoaming function, making it difficult for bubbles to be generated in the plug connector after injection molding, thereby improving the quality.

[0015] (2) The plug connector forming mold is installed with a spring barrel, a pressure column and a rigid spring. When the lower mold shakes up and down, the vibration force causes the bottom of the lower mold to press down the pressure column, causing the pressure column to compress the rigid spring in the spring barrel, and the pressure is dispersed through the resilience of the rigid spring. Guide grooves are opened on both sides of the spring barrel, and guide blocks are set on both sides of the bottom of the pressure column, which is beneficial to limit the range of movement of the rigid spring and prevent it from being twisted and offset.

[0016] (3) The plug connector forming mold is installed with a frame, a screw, a second rotating drive mechanism, a drive block and a guide sleeve. The second rotating drive mechanism drives the screw to rotate, so that the drive block moves up and down along the screw, which can realize the closing and opening of the upper mold and the lower mold, so that the forming mold has an integrated structure and does not need to be installed separately, thereby improving convenience during use.
