Description

Technical Field

[0001] This invention relates to the field of injection molds, and more particularly to injection molds and injection mold lower mold assemblies and embedding methods suitable for insert embedding. Background Technology

[0002] Injection molds can encapsulate electrical semi-finished products such as electromagnetic coils or plugs. During encapsulation, technicians typically embed the electrical semi-finished product as an insert into the groove of the lower injection mold. Then, when the upper and lower injection molds are closed, molten injection material is injected between the upper and lower injection molds. After cooling, the injection material wraps around the outer surface of the insert, thus achieving encapsulation of the insert.

[0003] However, in the aforementioned process, the dimensional accuracy of the insert is crucial when it is embedded in the groove, requiring the dimensional tolerance to be as small as possible. This is because if the insert is too large, its end face will press against and adhere tightly to the groove's end face when it enters, resulting in significant friction between the insert and the groove's end face. This makes it difficult for the insert to be successfully embedded, and the insert's end face is prone to scratches. Conversely, if the insert is too small, it is prone to movement after being embedded in the groove, resulting in low positioning accuracy and poor stability. This can lead to discrepancies between the actual and designed positions of the insert during injection molding, affecting the subsequent injection molding effect. Summary of the Invention

[0004] One advantage of this invention is that it provides an injection mold and an injection mold assembly and method suitable for insert embedding, which have low requirements for the dimensional accuracy of the insert, which is conducive to the smooth embedding of the insert and can ensure the positioning accuracy and stability of the insert after embedding.

[0005] To achieve at least one of the above advantages of the present invention, the present invention provides an injection molding lower mold assembly suitable for insert embedding, comprising: a lower mold having an embedding groove formed on its top surface, the embedding groove having a positioning end face; an embedding member connected to the insert and movable downward for driving the insert into the embedding groove; and a first mating member and a second mating member, the first mating member and the second mating member being disposed in the lower mold and located on opposite sides of the embedding groove, the first mating member and the second mating member each including a mating seat, one of the mating seat and the embedding member having a sliding portion, and the other having an inclined slide groove adapted to the sliding portion, the inclined slide groove extending inclinedly from bottom to top from one end of the inclined slide groove adjacent to the positioning end face to one end of the inclined slide groove away from the positioning end face;

[0006] Furthermore, when the sliding part is located at one end of the inclined groove, a horizontal gap is formed between the insert and the positioning end face in the horizontal direction; when the embedded part drives the insert to be embedded in the embedding groove, the sliding part slides close to the other end of the inclined groove to guide the embedded part to move horizontally towards the positioning end face, so that the insert can move horizontally close to and abut against the positioning end face while being embedded.

[0007] According to an embodiment of the present invention, the embedded part is provided with the inclined groove, the mating seat is provided with the sliding part, and when the sliding part is located at the lower end of the inclined groove, a horizontal gap is formed between the insert and the positioning end face in the horizontal direction. When the embedded part drives the insert to be embedded in the embedded groove, the upper end of the inclined groove slides close to the sliding part to guide the embedded part to move horizontally in the direction close to the positioning end face.

[0008] According to an embodiment of the present invention, the mating seat is provided with the inclined slide groove, the embedded member is provided with the sliding part, and when the sliding part is located at the upper end of the inclined slide groove, a horizontal gap is formed between the insert and the positioning end face in the horizontal direction. When the embedded member drives the insert to be embedded in the embedding groove, the sliding part slides close to the lower end of the inclined slide groove to guide the embedded member to move horizontally in the direction close to the positioning end face.

[0009] According to one embodiment of the present invention, the embedded part has a vertically extending lower sliding groove and an upper sliding groove. The lower sliding groove is connected to the lower end of the inclined sliding groove, and when the sliding part is located in the lower sliding groove, a horizontal gap is formed between the insert and the positioning end face. The upper sliding groove is connected to the upper end of the inclined sliding groove, and the sliding part is located in the upper sliding groove. The insert abuts against the positioning end face in the horizontal direction.

[0010] According to one embodiment of the present invention, the mating seat has a vertically extending lower sliding groove and an upper sliding groove. The lower sliding groove is connected to the lower end of the inclined sliding groove. When the sliding part is located in the lower sliding groove, the insert abuts against the positioning end face in the horizontal direction. The upper sliding groove is connected to the upper end of the inclined sliding groove. When the sliding part is located in the upper sliding groove, the horizontal gap is formed between the insert and the positioning end face.

[0011] According to one embodiment of the present invention, each of the sliding portions is provided with a rolling bearing adapted to be fitted within the inclined groove.

[0012] According to one embodiment of the present invention, the embedded part is provided with a insert shaft, which is adapted to be sleeved within the insert.

[0013] According to an embodiment of the present invention, each of the first mating member and the second mating member further includes a limiting seat and an elastic member. The limiting seat is disposed on the lower mold and is disposed away from the positioning end face relative to the mating seat. The elastic member is disposed between the limiting seat and the mating seat in a compressed state, for pressing the insert against the positioning end face through the mating seat.

[0033] Figure 1 This is a schematic diagram of the structure of an injection molding lower mold assembly 100 suitable for embedding the insert 900 according to an embodiment of the present invention. (See attached diagram) Figure 1 The injection molding lower mold assembly 100 suitable for embedding insert 900 of the present invention includes a lower mold 10, an embedded part 20, a first mating part 30 and a second mating part 40.

[0034] The lower mold 10 has an embedded groove 101 on its top surface, and the embedded groove 101 has a positioning end face 1011.

[0035] Figure 2 This is a schematic diagram of the structure of the embedded member 20 connected to the insert 900 according to an embodiment of the present invention. The embedded member 20 is connected to the insert 900 and can move downward, and is used to drive the insert 900 into the embedding groove 101 when the insert 900 is located directly above the embedding groove 101.

[0036] The first mating member 30 and the second mating member 40 are disposed on the lower mold 10 and located on opposite sides of the embedded groove 101. Both the first mating member 30 and the second mating member 40 include a mating seat 31. One of the mating seat 31 and the embedded member 20 has a sliding portion 311, and the other has an inclined groove 201 adapted to the sliding portion 311. The inclined groove 201 extends inclinedly from bottom to top, from one end of the inclined groove 201 adjacent to the positioning end face 1011 to the end of the inclined groove 201 away from the positioning end face 1011.

[0037] Figure 3 This is a schematic diagram illustrating the process by which the embedded member 20 drives the insert 900 into the embedment groove 101 according to an embodiment of the present invention. (See attached diagram.) Figure 3 When the sliding part 311 is located at one end of the inclined groove 201, a horizontal gap L is formed between the insert 900 and the positioning end face 1011 in the horizontal direction. When the embedding member 20 drives the insert 900 to be embedded in the embedding groove 101, the sliding part 311 slides closer to the other end of the inclined groove 201 to guide the embedding member 20 to move horizontally towards the positioning end face 1011, so that the insert 900 can move horizontally closer to the positioning end face 1011 while being embedded, thereby reducing the horizontal gap L between the end face of the insert 900 and the positioning end face 1011, so that the insert 900 can abut against the positioning end face 1011 after being embedded.

[0038] In other words, when the insert 900 is embedded in the injection molding lower mold assembly 100 as described above, the embedding method may include the following steps:

[0039] S10: Connect the insert 900 to the embedded part 20.

[0040] S20: By setting the sliding part 311 at one end of the inclined groove 201, the connection between the embedded part 20 with the insert 900 and the mating seat 31 is realized, and in this state, a horizontal gap L is formed between the insert 900 and the positioning end face 1011 in the horizontal direction.

[0041] S30: The embedded part 20 drives the insert 900 to be embedded downward into the embedded groove 101, thereby causing the sliding part 311 to slide close to the other end of the inclined groove 201 to guide the embedded part 20 to move horizontally towards the positioning end face 1011, so that the insert 900 can move horizontally to approach and abut against the positioning end face 1011 while being embedded.

[0042] In this way, as the insert 900 is gradually embedded into the embedding groove 101, it gradually approaches the positioning end face 1011 in the horizontal direction, rather than being immediately pressed against the positioning end face 1011 when it begins to enter the opening of the embedding groove 101. Therefore, the insert 900 can be smoothly embedded into the embedding groove 101. Furthermore, after the insert 900 is in place, it connects to the embedding member 20 and abuts against the positioning end face 1011, ensuring the positioning accuracy and stability of the insert 900 after embedding. Thus, the injection molding lower mold assembly 100 of the present invention, suitable for embedding the insert 900, facilitates the smooth embedding of the insert 900 and ensures the positioning accuracy and stability of the insert 900 after embedding.

[0043] In some preferred embodiments of the present invention, see [reference]. Figures 1 to 3 The embedded part 20 is provided with the inclined groove 201, and the mating seat 31 is provided with the sliding part 311. When the sliding part 311 is located at the lower end of the inclined groove 201, a horizontal gap L is formed between the insert 900 and the positioning end face 1011 in the horizontal direction. When the embedded part 20 drives the insert 900 to be embedded in the embedded groove 101, the upper end of the inclined groove 201 slides close to the sliding part 311 to guide the embedded part 20 to move horizontally towards the positioning end face 1011.

[0044] In some preferred embodiments of the present invention, the mating seat 31 is provided with the inclined groove 201, and the embedded member 20 is provided with the sliding portion 311. When the sliding portion 311 is located at the upper end of the inclined groove 201, a horizontal gap L is formed between the insert 900 and the positioning end face 1011 in the horizontal direction. When the embedded member 20 drives the insert 900 to be embedded in the embedding groove 101, the sliding portion 311 slides closer to the lower end of the inclined groove 201 to guide the embedded member 20 to move horizontally towards the positioning end face 1011.

[0045] Further, see Figures 1 to 3 The embedded part 20 has a vertically extending downward sliding groove 202 and an upper sliding groove 203. The downward sliding groove 202 communicates with the lower end of the inclined sliding groove 201, and the upper sliding groove 203 communicates with the upper end of the inclined sliding groove 201. When the sliding part 311 is located in the downward sliding groove 202, a horizontal gap is formed between the insert 900 and the positioning end face 1011 in the horizontal direction. The sliding part 311 is located in the upper sliding groove 203, and the insert 900 abuts against the positioning end face 1011 in the horizontal direction.

[0046] In other words, when the embedded part 20 is located above the embedded groove 101 and the sliding part 311 is assembled with the embedded part 20, the sliding part 311 can be directly assembled in the sliding groove 202 first. At this time, a horizontal gap is formed between the insert 900 and the positioning end face 1011 in the horizontal direction. Then, the embedded part 20 is moved vertically downward. This ensures that when the embedded part 20 drives the insert 900 to enter the embedded groove 101 vertically downward, a horizontal gap is also maintained between the insert 900 and the positioning end face 1011. In this way, the sliding groove 202 allows the end face of the insert 900 to avoid scratching when the insert 900 begins to enter the upper opening of the embedded groove 101, ensuring the aesthetics and quality of the insert 900. The upper groove 203 helps to ensure that after the insert 900 is embedded in the embedding groove 101, the end face of the insert 900 can always be pressed against the positioning end face 1011, which helps to further ensure the stability and positioning accuracy of the insert 900 after it is embedded.

[0047] Of course, it is understandable that when the mating seat 31 is provided with the inclined sliding groove 201 and the embedded part 20 is provided with the sliding part 311, the mating seat 31 can also form a vertically extending lower sliding groove 202 and an upper sliding groove 203. The lower sliding groove 202 communicates with the lower end of the inclined sliding groove 201, and the upper sliding groove 203 communicates with the upper end of the inclined sliding groove 201. When the sliding part 311 is located in the lower sliding groove 202, the insert 900 abuts against the positioning end face 1011 in the horizontal direction, and the sliding part 311 is located in the upper sliding groove 203. A horizontal gap is formed between the insert 900 and the positioning end face 1011 in the horizontal direction. In this way, the upper sliding groove 203 allows the end face of the insert 900 to avoid scratching when the insert 900 begins to enter the upper opening of the embedded groove 101, ensuring the aesthetics and quality of the insert 900. The sliding groove 202 helps to ensure that after the insert 900 is embedded in the embedding groove 101, the end face of the insert 900 can always be pressed against the positioning end face 1011, which helps to further ensure the stability and positioning accuracy of the insert 900 after it is embedded.

[0048] Furthermore, the sliding part 311 is cylindrical. In this way, when the embedded part 20 moves downward, the resistance between the sliding part 311 and the groove wall of the inclined slide groove 201 is small, which can prevent the sliding part 311 from being stuck by the inclined slide groove 201 and ensure that the sliding part 311 and the inclined slide groove 201 can always slide well together.

[0049] Furthermore, Figure 4 This is a schematic diagram of the structure when the first mating member 30 and the second mating member 40 of the present invention are connected to the embedded member 20. Each sliding part 311 is provided with a rolling bearing 3111 adapted to fit within the inclined groove 201. Thus, when the embedded member 20 moves downward, the outer ring of the rolling bearing 3111 will roll, thereby reducing the frictional resistance between the sliding part 311 and the inclined groove 201, preventing the sliding part 311 from being jammed by the inclined groove 201, and ensuring that the sliding part 311 and the inclined groove 201 can always slide well together.

[0050] Furthermore, each of the first mating member 30 and the second mating member 40 further includes a limiting seat 32 and an elastic member 33. The limiting seat 32 is disposed on the lower mold 10 and is located away from the positioning end face 1011 relative to the mating seat 31. The elastic member 33 is disposed in a compressed state between the limiting seat 32 and the mating seat 31, and is used to press the insert 900 against the positioning end face 1011 through the mating seat 31. In this way, after the embedded member 20 and the insert 900 are embedded in the embedding groove 101, the elastic member 33 in the compressed state can provide elastic force to the mating seat 31 and the embedded member 20, so that the embedded member 20 presses the insert 900 against the positioning end face 1011, which helps to ensure the stability of the insert 900 after it is embedded.

[0051] Furthermore, Figure 5 yes Figure 4 See the cross-sectional diagram of the middle component. Figure 5 The embedded part 20 is provided with a insertion shaft 21, which is adapted to be sleeved within the insert 900. Thus, the embedded part 20 is easy to install and disassemble when connected to the insert 900.

[0052] Specifically, the insert shaft 21 is inserted into the embedded part 20 and cooperates with the embedded part 20 to form a fixing slot 2101. The fixing slot 2101 is provided with the fixing pin 22 to fix the insert shaft 21 into the embedded part 20.

[0053] Below, referring to the specific embodiments described above, the present invention will be further described. Figures 1 to 5 The present invention details the specific process of embedding the insert 900 into the injection molding lower mold assembly 100, as follows:

[0054] S1: Fit the insert 900 onto the outside of the insert shaft 21 on the embedded part 20.

[0055] S2: The embedded part 20 with the insert 900 is placed directly above the embedded groove 101, and the sliding groove 202 is vertically aligned with the sliding part 311, and at this time, a horizontal gap is formed between the insert 900 and the positioning end face 1011 in the horizontal direction.

[0056] S3: Move the embedded part 20 downward, and the sliding part 311 slides relative to each other in the downward groove 202, so that the embedded part 20 can drive the insert 900 to enter the upper opening of the embedded groove 101 with a horizontal gap.

[0057] S4: Continue to move the embedded part 20 downwards, and the sliding part 311 slides from its lower end to its upper end in the inclined groove 201, so that when the embedded part 20 drives the insert 900 to continue to be embedded in the embedded groove 101, it also drives the insert 900 to move horizontally closer to the positioning end face 1011, so that the insert 900 can abut against the positioning end face 1011.

[0058] S5: Continue to move the embedded part 20 downwards, and the sliding part 311 slides relative to the upper end of the inclined groove 201 into the upper groove 203 to complete the embedding of the insert 900. At this time, the insert 900 is pressed against the positioning end face 1011 in the horizontal direction to ensure the positional accuracy and stability of the insert 900 after embedding.

[0059] Figure 6 This is a schematic diagram of the injection mold according to an embodiment of the present invention. Figure 6 The present invention also provides an injection mold comprising a lower injection mold assembly 100 and an upper injection mold 200 as described above. The upper injection mold 200 is disposed opposite to the lower injection mold assembly 100 and is used to cooperate with the lower injection mold assembly 100 to injection mold the insert 900.

The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been demonstrated and explained in the embodiments; any variations or modifications can be made to the implementation of the present invention without departing from these principles.
