[0014] A method for using an automobile connector part injection mold with a material taking function, comprising the following steps: Step 1: When in use, the external moving arm drives the movable mold frame to move, so that the movable mold frame and the static mold frame are nested and closed, and the external injection machine is started to inject the molten liquid into the cavity of the static mold frame through the injection hole. After injection filling, the external cold water supply mechanism is started to input cooling water into the liquid inlet; Step 2: As the cooling water is input into the liquid inlet, and is input into the assembly groove through the annular cavity and the middle groove, and is input into the interior of the movable adapter assembly, the control valve is kept open. The cooling water input into the movable adapter assembly absorbs the heat inside the cavity directly through the adapter plate, and is introduced into the cooling cavity through the outer cavity and the connecting hole for cooling. Step 3: After the injection molding is completed and cooled and solidified, the intermittent push component is started, the connecting ring drives the bottom arc-shaped protrusion to rotate, and the ejector rod of the movable adapter component is intermittently pushed, so that each group of movable adapter components moves up and down along the adapter groove and is stably peeled off from the internally solidified molded parts; Step 4: After dynamic stripping is completed, the control valve is closed to block the coolant input into the cooling chamber. As the coolant is continuously fed in to fill the outer cavity and the movable adapter assembly, the hydraulic pressure in the movable adapter assembly increases, and the internally nested clamping assembly is pushed to move, clamping along the outer side of the stripped part. At the same time, the ejector assembly is started, and the external movable arm drives the movable mold frame to move horizontally. The ejector assembly pushes the part outward from the inside and simultaneously removes the part from the static mold frame. After the part is taken out of the cavity, as the movable adapter assembly moves out of the adapter slot, the hydraulic action disappears, the clamping assembly automatically resets, and the removed part is automatically released downward, and the collection is completed in cooperation with the bottom collection part.

[0015] The beneficial effects of the present invention are as follows: (1) The present invention utilizes a movable adapter component added to the movable mold frame and adapts it to the adapter groove provided in the static mold frame. In the actual injection molding process, the molded part is directly molded between the mold cavity and the inner wall of the movable adapter component, so that the outer area of ​​part of the molded part contacts the movable adapter component. After molding and curing, the intermittent pushing component is used to drive multiple groups of movable adapter components to move back and forth, and realize the peeling of the contact area with the outer side of the molded part. While peeling quickly, the original contact area is reciprocated and rubbed to trim, thereby reducing the contact area of ​​the molded part in the static mold frame cavity, combining the dynamic peeling of the movable adapter component, and cooperating with the basic function of the ejector pin component, so as to improve the effect of taking out and separating the molded part from the static mold frame, reduce the adhesion area, and also perform auxiliary grinding and trimming on the local outer side surface, which actually has the effect of easier material removal and separation and auxiliary trimming of the outer side surface, and the comprehensive molding and separation efficiency is high.

[0016] (2) The present invention reuses the movable adapter component and cooperates with the elastically connected and nested clamping component in the movable adapter component. After the movable adapter component reciprocates and completes the stripping with the molded part, the cooling water is fed into the movable adapter component and the clamping component is hydraulically driven to move, so that the clamping block moves and clamps on the outside of the molded part, thereby realizing the clamping of the molded part in the molding cavity. No additional clamping equipment is required. The molded part is directly clamped out of the static mold frame by the movement of the movable mold frame. The above-mentioned stripping and the clamping action are combined with the action of the ejector assembly to realize fast and stable clamping processing. When the part is clamped and removed from the static mold frame, the pressure-releasing movable adapter component is used to automatically release the removed part, and the clamped part is automatically released downward and falls out, thereby saving the investment in special clamping equipment. At the same time, the clamping efficiency is high and the separation speed is fast.

[0017] (3) The present invention reuses the coolant guide of the movable adapter component and cooperates with the corresponding conducting mechanism set in the static mold frame. By controlling the coolant in the movable adapter component, the coolant is directly conducted to the cooling chamber by continuously inputting cooling water before molding and solidification. Before clamping, the guided cooling water is used to achieve rapid cooling of the injection liquid in cooperation with the cooling chamber and the adapter plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Embodiment: When in use, the external movable arm is started and the movable mold frame 2 is driven to move horizontally, so that the movable mold frame 2 and the static mold frame 1 are nested and closed, and the external injection machine is started to inject the molten liquid into the cavity 4 of the static mold frame 1 through the injection hole 3. After injection filling, the external cold water supply mechanism is started to input cooling water into the liquid inlet 14. As the cooling water is input into the liquid inlet 14, it is input into the assembly groove 12 through the annular cavity 16 and the middle groove 17, and is directly input into the interior of the guide cavity 134 through the first port 135 through the connection of the movable adapter component 13 in the assembly groove 12, and the cooling water input into the guide cavity 134 of the movable adapter component 13 is directly input into the guide cavity 134 through the adapter plate 131.

After the part is taken out of the cavity 4, as the movable adapter assembly 13 is moved out of the adapter groove 6, the cooling water introduced into the movable adapter assembly 13 is discharged, the hydraulic action disappears, the clamping assembly 15 automatically resets, and the taken-out part is automatically released downward, and the collection is completed in cooperation with the bottom collection part.

[0023] Firstly, by utilizing the movable adapter component 13 added in the movable mold frame 2 and adapting it to the adapter groove 6 provided in the static mold frame 1, in the actual injection molding process, the molded part is directly molded between the cavity 4 and the inner wall of the movable adapter component 13, so that the outer area of ​​part of the molded part is in contact with the movable adapter component 13, and after molding and curing, the intermittent pushing component 11 is used to drive multiple groups of movable adapter components 13 to move back and forth, and realize the peeling of the contact area with the outer side of the molded part, and at the same time of rapid peeling, the original contact area is reciprocated and rubbed to trim, thereby reducing the contact area of ​​the molded parts in the cavity of the static mold frame 1, and combining the dynamic peeling of the movable adapter component 13, cooperating with the basic function of the ejector component 5, improving the effect of removing and separating the molded parts from the static mold frame 1, reducing the adhesion area, and also performing auxiliary grinding and trimming on the local outer side surface, which actually has the effect of easier material separation and auxiliary trimming of the outer side surface, and the comprehensive molding and separation efficiency is high.

10. The method for using the injection mold for automobile connector parts with a material taking function according to any one of claims 1 to 9, characterized in that: The usage steps include the following: Step 1: When in use, the external movable arm drives the movable mold frame (2) to move, so that the movable mold frame (2) and the static mold frame (1) are nested and closed, and the external injection machine is started to inject molten liquid into the mold cavity (4) of the static mold frame (1) through the injection hole (3). After injection filling, the external cold water supply mechanism is started to input cooling water into the liquid inlet (14); Step 2: As the cooling water is input into the liquid inlet (14), and is input into the assembly groove (12) through the annular cavity (16) and the intermediate groove (17), and is input into the interior of the movable adapter component (13), the control valve (9) is kept open. The cooling water input into the movable adapter component (13) absorbs the internal heat of the cavity (4) directly through the adapter plate (131), and is introduced into the cooling cavity (19) through the outer cavity (7) and the connecting hole (8) for cooling. Step 3: After the injection molding is completed and cooled and solidified, the intermittent pushing component (11) is started, the connecting ring (112) drives the bottom arc-shaped protrusion (114) to rotate, and intermittently pushes the top rod (132) of the movable adapter component (13), so that each group of movable adapter components (13) moves up and down along the adapter groove (6) and is stably peeled off from the internally solidified molded parts; Step 4: After the dynamic stripping is completed, the control valve (9) is closed to block the coolant input into the cooling chamber (19). As the coolant is continuously fed in to fill the outer chamber (7) and the movable adapter assembly (13), the hydraulic pressure in the movable adapter assembly (13) is increased, and the internally nested clamping assembly (15) is pushed to move, clamping along the outer side of the stripped part. At the same time, the ejector assembly (5) is started, and the external movable arm drives the movable mold frame (2) to move horizontally. The ejector assembly (5) pushes the part outward from the inside and synchronously removes the part from the static mold frame (1). When the part is removed from the cavity (4), as the movable adapter assembly (13) is removed from the adapter groove (6), the hydraulic pressure disappears, the clamping assembly (15) automatically resets, and the removed part is automatically released downward, and the collection is completed in cooperation with the bottom collection part.
