Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of in-mold injection, especially to a sliding connector forming die. BACKGROUND

[0002] Referring to Figure 1 The existing connector comprises an internal metal piece 100b and an injection part 100a fixed on the outer circumferential surface of the internal metal piece 100b at the middle position by the in-mold injection process.

[0003] Before the injection operation of the injection part 100a, the internal metal piece 100b needs to be placed into the mold cavity of the forming die of the injection part 100a. In theory, the size of the mold cavity of the forming die should be consistent with the internal metal piece 100b, so that the internal metal piece 100b remains stable after being placed into the mold cavity.

[0004] In fact, there is a certain inspection deviation in mold processing, especially when the length of the internal metal piece 100b is relatively long, it is difficult to make the size of the mold cavity of the forming die match the length of the internal metal piece 100b, and there is often a deviation of about 1mm. If the size of the mold cavity of the forming die is 1mm smaller than the length of the internal metal piece 100b, the internal metal piece 100b cannot be smoothly placed into the mold cavity.

[0005] In order to avoid the situation that the internal metal piece 100b cannot be placed into the mold cavity, the size of the mold cavity of the forming die is generally made to be 1mm longer than the length of the internal metal piece 100b, which will cause the internal metal piece 100b to be not firmly positioned, resulting in burrs and other defects in the injection part 100a obtained by injection.

[0006] Therefore, it is necessary to improve the existing forming die to solve the problem that the size of the mold cavity is difficult to match the internal metal piece, resulting in burrs and other defects in the obtained injection part.

[0007] The above information disclosed in the background section is only included to enhance the understanding of the background of the disclosure, and therefore can contain information that is not prior art known to those of ordinary skill in the art at the present time. UTILITY MODEL CONTENTS

[0008] One purpose of the utility model is to provide a sliding connector forming die, which can effectively solve the problem that the size of the mold cavity of the existing forming die is difficult to match the internal metal piece, resulting in burrs and other defects in the obtained injection part.

[0009] To achieve the above purpose, the utility model provides a sliding connector forming die, which comprises:

[0010] A lower mold assembly is provided with a mold cavity for injection molding an injection part;

[0011] A fixed insert is mounted on the lower mold assembly and is provided with a fixed slot for one end of the inner metal piece to extend into, corresponding to the position of the mold cavity;

[0012] A sliding assembly is slidingly arranged at a side position of the lower mold assembly and is arranged opposite to the other end of the inner metal piece;

[0013] An upper mold assembly is used to push the sliding assembly after the lower mold assembly is combined with the upper mold assembly, so that the sliding assembly pushes the other end of the inner metal piece to clamp and fix the inner metal piece with the fixed insert.

[0014] Optionally, an upper part of the fixed insert is provided with an insert inclined surface for abutting against the upper mold assembly, away from one side of the sliding assembly, and the horizontal distance of the insert inclined surface to the mold cavity gradually increases from top to bottom.

[0015] Optionally, the upper mold assembly is provided with a fixed inclined pushing surface for pushing the insert inclined surface, corresponding to the position of the insert inclined surface.

[0016] Optionally, one side of the sliding assembly away from the fixed insert is provided with a sliding inclined surface for abutting against the upper mold assembly, and the horizontal distance of the sliding inclined surface to the mold cavity gradually increases from top to bottom.

[0017] Optionally, the upper mold assembly is provided with a sliding inclined pushing surface for pushing the sliding inclined surface, corresponding to the position of the sliding inclined surface.

[0018] Optionally, the sliding assembly comprises an inclined sliding plate provided with the sliding inclined surface and slidingly arranged with the lower mold assembly, and a flow channel plate fixedly arranged on one side of the inclined sliding plate close to the inner metal piece.

[0019] The hardness of the inclined sliding plate is greater than that of the flow channel plate.

[0020] Optionally, the lower mold assembly is provided with a plurality of fixed flow channels, and the flow channel plate is provided with a movable flow channel, and part of the fixed flow channels are communicated through the movable flow channel.

[0021] Optionally, the flow channel plate is provided with a pushing rubber block corresponding to the position of the inner metal piece.

[0022] The beneficial effects of the utility model lie in: providing a sliding connector forming mold, and the working process is as follows:

[0023] S10: Preparation stage: First, one end of the internal metal piece is inserted into a fixed slot in the fixed insert on the lower mold assembly. This fixed slot is designed to accommodate one end of the internal metal piece and ensure its stable positioning.

[0024] S20: Place the metal piece: Then, the other end of the internal metal piece is placed opposite the sliding assembly. The sliding assembly is located on the side of the lower mold assembly and can slide along a certain trajectory.

[0025] S30: Mold closing operation: Next, the mold closing operation is performed, that is, the upper mold assembly is closed with the lower mold assembly. In this process, the upper mold assembly pushes the sliding assembly.

[0026] S40: Fix the metal piece: After the sliding assembly is pushed by the upper mold assembly, it moves towards the internal metal piece, thereby pushing the internal metal piece to tightly adhere to the fixed insert. In this way, the two ends of the internal metal piece are fixed by the fixed insert and the sliding assembly, ensuring the correct positioning of the metal piece in the entire mold.

[0027] S50: Injection operation: After the internal metal piece is fixed, the injection operation can be performed. The plastic material is injected into the mold cavity and molded around the internal metal piece in the mold cavity to form an injection part.

[0028] The sliding connector forming mold provided by the utility model uses the fixed insert and the slidable sliding assembly to cooperate to clamp and fix the internal metal piece, and the combination of the fixed insert and the sliding assembly can form a fine clamping system inside the mold, thereby making up for the size mismatch problem. The design of the sliding assembly allows a certain range of size variation, which means that even if the length of the internal metal piece varies, the sliding assembly can adjust the position accordingly to ensure that the metal piece is fixed correctly.

[0029] Since the internal metal piece is firmly clamped in the mold, the internal metal piece will not shift during the injection process, so that the burrs and other defects of the injection part caused by insecure positioning of the internal metal piece can be effectively avoided.

[0030] Therefore, the sliding connector forming mold provided by the utility model can effectively solve the problem that the size of the mold cavity of the existing forming mold is difficult to match the internal metal piece, resulting in burrs and other defects in the obtained injection part.

[0050] Referring to Figures 2-4 The utility model provides a sliding connector forming die, comprising:

[0051] Lower die assembly 1, lower die assembly 1 is equipped with the cavity 101 for injection molding injection molding part 100a,

[0052] Fixed insert 2, fixed insert 2 is installed on lower die assembly 1, and the position corresponding to the cavity 101 is equipped with fixed slot 201 for the one end of internal metal piece 100b to extend into,

[0053] Sliding assembly 3, sliding assembly 3 is slidably arranged at the side position of lower die assembly 1 and is oppositely arranged with the other end of internal metal piece 100b,

[0054] Upper die assembly 4, upper die assembly 4 is used to push sliding assembly 3 after the die closing of lower die assembly 1, so that the other end of internal metal piece 100b is pushed by sliding assembly 3 to cooperate with fixed insert 2 to clamp and fix internal metal piece 100b.

[0055] The sliding connector forming die provided by the embodiment has the following working process:

[0056] S10: preparation stage: first, one end of internal metal piece 100b is inserted into fixed slot 201 in fixed insert 2 on lower die assembly 1. This fixed slot 201 is designed to accommodate one end of internal metal piece 100b and ensure its stable position.

[0057] S20: placing metal piece: then, the other end of internal metal piece 100b is placed opposite sliding assembly 3. Sliding assembly 3 is located at the side of lower die assembly 1 and can slide along a certain trajectory.

[0058] S30: die closing operation: next, the die closing operation is carried out, that is, upper die assembly 4 is folded with lower die assembly 1. In this process, upper die assembly 4 pushes sliding assembly 3.

[0059] S40: Fixing metal piece: After the sliding assembly 3 is pushed by the upper die assembly 4, the sliding assembly 3 moves towards the internal metal piece 100b, thereby pushing the internal metal piece 100b and making the internal metal piece 100b tightly adhere to the fixed insert 2. In this way, the two ends of the internal metal piece 100b are fixed by the fixed insert 2 and the sliding assembly 3 respectively, so as to ensure the correct positioning of the metal piece in the whole mold.

[0060] S50: Injection operation: After the internal metal piece 100b is fixed, the injection operation can be performed. The plastic material is injected into the mold cavity 101 and is formed around the internal metal piece 100b in the mold cavity 101 to form the injection part 100a.

[0061] The sliding connector forming mold provided by the utility model can effectively solve the problem that the size of the mold cavity 101 of the existing forming mold is difficult to match the internal metal piece 100b, so that the injection part 100a obtained has burrs and other defects.

[0062] Because the internal metal piece 100b is firmly clamped in the mold, the internal metal piece 100b will not displace during the injection process, so that burrs and other defects of the injection part 100a caused by the insecure positioning of the internal metal piece 100b can be effectively avoided.

[0063] Therefore, the sliding connector forming mold provided by the utility model can effectively solve the problem that the size of the mold cavity 101 of the existing forming mold is difficult to match the internal metal piece 100b, so that the injection part 100a obtained has burrs and other defects.

[0064] In the embodiment, the upper part of the fixed insert 2 away from the side of the sliding assembly 3 is provided with an insert inclined surface 202 for abutting with the upper die assembly 4, and the horizontal distance from the insert inclined surface 202 to the mold cavity 101 gradually increases from top to bottom. Correspondingly, the upper die assembly 4 is provided with a fixed inclined pushing surface 401 corresponding to the position of the insert inclined surface 202 for pushing the insert inclined surface 202. This design can ensure that the upper die assembly 4 stably abuts against the fixed insert 2 during the mold closing process, thereby uniformly transmitting the force and improving the fixing effect of the internal metal piece 100b.

[0065] Further, the slide assembly 3 is provided with a slide inclined surface 3011 on the side away from the fixed insert 2, which is used to abut against the upper die assembly 4. The horizontal distance of the slide inclined surface 3011 to the mold cavity 101 gradually increases from top to bottom. Correspondingly, the upper die assembly 4 is provided with a slide inclined pushing surface 402 corresponding to the position of the slide inclined surface 3011, which is used to push the slide inclined surface 3011. The design of the slide inclined surface 3011 and the slide inclined pushing surface 402 helps the slide assembly 3 to move smoothly during the clamping of the mold, and further ensures the stable clamping of the internal metal part 100b.

[0066] Optionally, the slide assembly 3 comprises an inclined slide plate 301 provided with the slide inclined surface 3011 and slidingly arranged with the lower die assembly 1, and a runner plate 302 fixedly arranged on the side of the inclined slide plate 301 close to the internal metal part 100b. The hardness of the inclined slide plate 301 is greater than that of the runner plate 302.

[0067] The lower die assembly 1 is provided with a plurality of fixed runners 102, and the runner plate 302 is provided with movable runners 3021. Part of the fixed runners 102 are communicated through the movable runners 3021. Arranging part of the runners on the runner plate 302 is beneficial to reduce the size of the lower die assembly 1, and further improve the compactness of the structure. The hardness of the runner plate 302 is smaller, which is beneficial to the processing and manufacturing of the movable runners 3021.

[0068] In the embodiment, the runner plate 302 is provided with a pushing rubber block 303 corresponding to the position of the internal metal part 100b. When the slide assembly 3 is close to the internal metal part 100b, the pushing rubber block 303 directly pushes the end surface of the internal metal part 100b. The pushing rubber block 303 has a soft texture, which can deform appropriately within a certain range to press the internal metal part 100b, and can also avoid the internal metal part 100b from being damaged.

[0069] Optionally, a spring can be arranged between the slide assembly 3 and the lower die assembly 1. When the upper die assembly 4 is opened upward, the spring automatically pushes the slide assembly 3 away from the lower die assembly 1, so that the slide assembly 3 automatically releases the internal metal part 100b.

[0070] In summary, the slide connector forming mold provided by the embodiment has the following advantages:

[0071] ① Accurate positioning ability: through the cooperation of the fixed insert 2 and the slide assembly 3, the internal metal part 100b can be accurately positioned. Even if there is a small size deviation between the mold and the metal part, the stable positioning of the metal part can also be ensured through the adjustment of the slide assembly 3.

[0072] ② Reduction of burrs and other defects: Since the internal metal part 100b is firmly fixed during the injection molding process, it can effectively reduce the burrs and other defects caused by the displacement of the metal part, improving the quality of the injection molded product.

[0073] ③ Strong adaptability: The design of the sliding assembly 3 allows for a certain range of size changes, which means that the mold can adapt to internal metal parts 100b of different lengths, improving the versatility and adaptability of the mold.

[0074] ④ Fine-tuning system: The fixed insert 2 and the sliding assembly 3 form a fine-tuning clamping system that can fine-tune the position of the internal metal part 100b during mold closing, ensuring the accuracy of injection molding.

[0075] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of the present application, they do not limit the scope of the patent protection of the present application. Any equivalent structure or equivalent process substitution or modification based on the essential concept of the present application, using the content described in the specification and drawings, and directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, etc., are all included within the scope of the patent protection of the present application.
