They should not be construed as limiting the specific protection scope of this utility model.

[0014] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" or "a number" means two or more, unless otherwise explicitly specified.

[0015] See the attached drawings. The material-saving connector accessory molding device described in this embodiment includes a front mold base 1, a rear mold base 2, and an ejection mechanism 3. The front mold base 1 has a front mold core 11 in the middle, and the front mold core 11 has two first molding grooves 12 that are symmetrically arranged on the left and right. The rear mold base 2 has a rear mold core 21 in the middle, and the rear mold core 21 has two second molding grooves 22 that are symmetrically arranged on the left and right. The first molding grooves 12 and the second molding grooves 22 are combined to form a cavity.

[0016] The rear mold frame 2 is provided with a slider 23, which has an oblique insertion hole 24. Two insertion posts 25 are fixed at the front end of the slider 23. The front ends of the two insertion posts 25 are provided with forming parts 26, which can be inserted into two cavities respectively. The forming parts 26 can form an insertion hole 41 on the connector accessory 4. The front mold frame 1 is provided with an oblique insertion rod 13, which is inserted into the oblique insertion hole 24. At the same time, a limiting block 14 is fixed on the front mold frame 1. The limiting block 14 is located behind the slider 23, and the contact surfaces of the limiting block 14 and the slider 23 are both inclined surfaces.

[0017] When the current mold base 1 and the rear mold base 2 are closed, the inclined insert rod 13 drives the slider 23 to push the insert into the cavity, allowing the molding part 26 to be inserted into the cavity. At the same time, the limiting block 14 presses down, and the inclined surface synchronously pushes the slider 23 to one side of the cavity, preventing the slider 23 from shifting and causing the insert position to deviate, thus further ensuring the molding accuracy of the parts. When the current mold base 1 and the rear mold base 2 are separated, the limiting block 14 moves away from the rear side of the slider 23, and at the same time, the inclined insert rod 13 drives the slider 23 to move to the rear side, causing the insert 25 to leave the cavity.

[0018] A fixing plate 27 is installed on the side of the rear mold frame 2, and the fixing plate 27 has a through hole; a support rod 28 is fixed to the rear end of the slider 23, and the tail of the support rod 28 passes through the through hole of the fixing plate 27; a spring 29 is fitted on the support rod 28, with one end of the spring 29 abutting against the end of the support rod 28 and the other end abutting against the fixing plate 27. The spring 29 makes the slider 23 and the inclined insertion rod 13 more stable and less prone to shaking.

[0019] The front mold base 1 is provided with a first sprue groove 15, which connects the first molding groove 12 to the side of the front mold base closest to the first molding groove. The rear mold base 2 is provided with a second sprue groove 210, which connects the second molding groove 22 to the side of the rear mold base closest to the second molding groove. When the front mold base 1 and the rear mold base 2 are assembled, the first sprue groove 15 and the second sprue groove 210 are combined to form a sprue runner 211, which is connected to the cavity. The inlet 212 of the sprue runner 211 is located at the assembly point of the front mold base 1 and the rear mold base 2 closest to the cavity. The sprue runner 211 is Y-shaped, located in the middle of the two cavities, and its outlet connects to the two cavities respectively.

[0020] The ejection mechanism 3 includes an ejection base 31 and an ejector pin 32. The second molding groove 22 and the second sprue groove 210 are provided with ejector pin holes 213 for the ejector pin 32 to pass through. The ejector pin 32 can eject the die-cast connector parts 4 and the waste residue together to complete the demolding.

[0021] The die-casting process is as follows: Before die casting, the liquid material required for molding the connector parts (such as aluminum alloy liquid, etc., selected according to the material of the parts) is heated to a suitable temperature to ensure that the liquid material has good fluidity and meets the die casting requirements.

[0022] During die casting, the front mold base 1 and the rear mold base 2 are driven to move towards each other until they are completely joined. At this time, the first forming groove 12 on the front mold base 1 and the second forming groove 22 on the rear mold base 2 are precisely joined to form a complete cavity. At the same time, the sprue grooves on the opposite sides of the front mold base 1 and the rear mold base 2 are joined to form a sprue runner 211. The inlet 212 of the sprue runner is located at the joining point of the mold base closest to the cavity.

[0023] During mold closing, the angled insert rod 13 on the front mold base 1 is simultaneously inserted into the angled insertion hole 24 of the slider 23 on the rear mold base 2. As the mold base continues to assemble, the angled insert rod 13, guided by the angled insertion hole 24, pushes the slider 23 forward until the insert 25 with the forming part 26 at the front end of the slider 23 is precisely inserted into the cavity. The forming part 26 of the insert 25 and the cavity together form the complete forming space of the connector accessory 4. At the same time, the limiting block 14 on the front mold base 1 contacts the inclined surface of the slider 23 to limit the position of the slider 23 and prevent the insert from shifting due to excessive movement of the slider.

[0024] The heated molten metal is injected into the runner 211 at a uniform speed through the inlet 212. Since the inlet of the runner is close to the mold cavity, the molten metal flows rapidly into the mold cavity along the runner and quickly fills the internal space of the mold cavity, leaving only a small amount of molten metal in the runner during the process.

[0025] After the molten material is injected, keep the front mold base 1 and the rear mold base 2 in the closed state, and wait for the molten material inside the cavity to cool naturally or be cooled faster by the mold cooling system until the molten material solidifies to form a connector accessory that matches the shape of the cavity. At the same time, the residual molten material in the gating channel also cools and solidifies.

[0026] The demolding steps are as follows: After the molten material has completely cooled and solidified, the front mold base 1 and the rear mold base 2 are driven to move in opposite directions to open the mold. During the mold opening process, the inclined insertion rod 13 of the front mold 1 is gradually pulled out from the inclined insertion hole 14 of the slider 23. Under the elastic force of the spring on the rear support rod, the slider 23 moves backward along the guide structure of the rear mold base 2, driving the insertion post 25 to be pulled out from the cavity and return to the initial position.

[0027] The ejection mechanism 3 is activated, and the ejection base 31 drives the ejector pins 32 to move upward along the ejector pin holes on the cavity and the gating channel. The ejector pins first contact the molded connector parts 4 in the cavity and eject them from the cavity; at the same time, another part of the ejector pins contact the cooled residual material in the gating channel 211 and eject it from the channel. The ejected connector parts 4 and residual material are collected manually or mechanically to complete the demolding process.

[0028] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
