[0002] The plug is an important component that connects electrical appliances and power sources. One end is inserted into a power socket, and the other end is connected to an electrical appliance or other electrical equipment to provide power supply or signal transmission. The plug mold is a tool specially used to produce plugs. The use of this mold not only greatly improves production efficiency and reduces labor costs, but also improves product quality and consistency.

[0003] The mold of the plug can be customized according to the manufacturer's needs. The mold needs to be combined with the upper and lower mold bases. During production, the plugs are inserted into the mold slots in turn and fixed, and then the mold is placed in the cavity of the lower mold base to facilitate subsequent injection molding. When demolding, the produced plug workpieces need to be manually pulled out of the mold one by one. This demolding method is relatively cumbersome and greatly reduces the efficiency of demolding.

[0034] Example:

[0035] See also Figure 1 - Figure 6 A plug mold demoulding device includes a lower mold base 1 and an upper mold base 101. The upper mold base 101 is arranged on the lower mold base 1. A plug module 102 is arranged in the lower mold base 1 for connecting to a workpiece 103. A fixing frame 2 and a fixing sleeve 201 are provided at one end of the lower mold base 1 for limiting the wire end of the workpiece 103. The fixing sleeve 201 is set to be no less than the workpiece 103.

[0036] Some implementation methods of the present application are described in detail below with reference to the accompanying drawings:

[0037] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The plug mold demoulding device of the present application is mainly composed of a lower mold base 1, an upper mold base 101 and a plug module 102. The plug module 102 is used to cooperate with the insertion of the plugs of multiple workpieces 103. After the plugs are inserted into the mold slots in turn and fixed, the plug module 102 and the workpieces 103 are placed in the cavity of the lower mold base 1 as a whole to complete the subsequent injection molding work. At this time, in order to facilitate the demoulding work, a fixing frame 2 for simultaneously limiting the wires of multiple workpieces 103 is provided at the front end of the lower mold base 1, and the wires of the workpieces 103 are restricted on the outer wall of the lower mold base 1 in turn, wherein the fixing sleeve 201 corresponds to the wire end of the workpiece 103 and is evenly installed inside the fixing frame 2, so that The wires of the workpiece 103 passing through the fixing frame 2 and the lower die base 1 can be clamped into the fixing sleeve 201 in turn. The design between the fixing frame 2 and the lower die base 1 allows the fixing sleeve 201 to tightly fix the wires of the workpiece 103 on the lower die base 1. During operation, they can also be fixed manually. In this way, after fixing the wires of most workpieces 103 on the outer wall of the lower die base 1 at the same time, during the subsequent demolding work, it is only necessary to take out the plug module 102 from the inside of the lower die base 1, and then bend it in the reverse direction to directly pull out the plug module 102 and separate it from the workpiece 103. This design eliminates the need to manually pull out the workpieces 103 one by one, which not only brings convenience to the workers but also improves the efficiency of demolding.

[0038] In some embodiments, the present application further provides a wire groove 3 matching the wire of the workpiece 103, so that the wire end of the workpiece 103 that is led out to the outside of the lower die base 1 and the upper die base 101 can pass along the inside of the wire groove 3 and be led out from the front of the base of the lower die base 1, thereby increasing the friction at the connection and avoiding left-right displacement;

[0039] The present application sets a hydraulic mechanism 5, which is located on both sides of the fixed frame 2 and connected to the outer wall of the lower die base 1. The hydraulic mechanism 5 controls the extension of its hydraulic rod to push out the fixed frame 2 as a whole. When retracting, the fixed frame 2 is driven to move, and the fixed sleeve 201 fixes the wire on the outer wall of the lower die base 1 and locks it. The design of the hydraulic mechanism 5 makes it easy to control the forward and backward movement of the fixed frame 2 to put in the wire of the workpiece 103.

[0040] See also Figure 4 , Figure 5 and Figure 6 In the present application, a bottom plate 501 is also provided, wherein the bottom plate 501 is installed at the tail of the hydraulic mechanism 5 to fix the hydraulic mechanism 5 on the outer wall of the lower die base 1, and the two can be connected by four-corner bolts to facilitate disassembly and assembly.

[0041] The present application also provides a bracket 6 and a connecting plate 601. The bracket 6 is installed at the ejection end of the hydraulic rod of the hydraulic mechanism 5. The connecting plates 601 are respectively installed on both sides of the fixed frame 2. When the two ends inside the fixed frame 2 are attached to the outer wall of the lower mold base 1, the connecting plate 601 can be correspondingly inserted into the end of the bracket 6 away from the connection with the hydraulic rod of the hydraulic mechanism 5. At this time, the connecting plate 601, the bracket 6 and the bottom plate 501 can be on the same horizontal line as the fixed frame 2, and the three can be fixed together with the installation structure. This method is also convenient for the subsequent combination and installation of parts.

[0042] The installation and disassembly structure in the present application is mainly applied by combining a lock plate 7, a handle 701 and a limit spring 702, wherein the lock plate 7 can be movably inserted in a groove where the connecting plate 601, the bracket 6 and the bottom plate 501 are on the same horizontal line, and the lock plate 7 and the handle 701 are designed as an integrated structure, one end of the limit spring 702 is installed on the inner wall of the handle 701, and the other end is installed in the groove of the bottom plate 501. Under the action of the elastic force of the limit spring 702, the lock plate 7 is fixed in the groove of the connecting plate 601, the bracket 6 and the bottom plate 501 to connect them. By pulling the handle 701 outward, the handle 701 is driven to move under the action of force, and the limit spring 702 is stretched, so that the lock plate 7 can be pulled out to perform a separation operation.

[0043] See also Figure 3 and Figure 5 In the present application, a card insertion rod 202 and a card insertion port 203 are also provided. The card insertion port 203 is correspondingly installed on both sides of the fixed sleeve 201 that is in contact with the lower die base 1. The card insertion port 203 is arranged to match the card insertion rod 202 and is located on both sides of the wire groove 3. When the fixed sleeve 201 locks the wire end of the workpiece 103 on the outer wall of the lower die base 1, the card insertion rod 202 is driven to be inserted into the card insertion port 203 to further improve the stability of the connection between the fixed sleeve 201 and the lower die base 1 and ensure the overall use effect.

[0044] See also Figure 1 , Figure 3 and Figure 4 In the present application, a positioning cylinder 4 and an inner cylinder pad 401 are also provided. The positioning cylinder 4 is provided with multiple groups, which are respectively fixed on the upper parts of the wire groove 3. When the wire of the workpiece 103 is driven to pass through the fixing frame 2, the positioning cylinder 4 is designed to have an opening with elasticity, and the wire is driven by the opening to be clamped into the inside of the positioning cylinder 4, which is opposite to the fixing direction of the fixing sleeve 201, so as to further fix the wire of the workpiece 103. A matching inner cylinder pad 401 is glued inside each positioning cylinder 4, and the inner cylinder pad 401 is designed with rubber material. When the positioning cylinder 4 fixes the wire, the inner cylinder pad 401 fits with the outer wall of the wire, so as to further increase the friction of the connection and make the connection more stable.
