Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to an injection mold component with an eccentric structure. Background Art

[0002] Injection molding is a process suitable for mass production of parts with complex shapes. The process first involves combining the male and female molds to form a complete mold cavity. The injection molding machine then applies high pressure to the molten plastic, causing it to eject and fill the mold cavity. After a series of processes such as pressure holding and cooling, the mold can be opened and the finished product can be removed.

[0003] When the male and female molds are closed under high pressure, the compression force during the closing process acts directly on them and is borne by the supporting structure used to support them. When the male and female molds use an eccentric mold structure, the area on the supporting structure that directly bears the compression force during the closing process is not located at its central fulcrum. This can easily lead to uneven deformation of the supporting structure under the eccentric force, which can affect the fit accuracy between the male and female molds, reduce the quality of the injection molded product, and even shorten the service life of the injection molding equipment. Utility Model Content

[0038] Injection molding is a process suitable for mass production of parts with complex shapes. The process first involves combining the male and female molds to form a complete mold cavity. The injection molding machine then applies high pressure to the molten plastic, causing it to eject and fill the mold cavity. After a series of processes such as pressure holding and cooling, the mold can be opened and the finished product can be removed.

[0039] When the male and female molds are closed under high pressure, the compression force during the closing process acts directly on them and is borne by the supporting structure used to support them. When the male and female molds use an eccentric mold structure, the area on the supporting structure that directly bears the compression force during the closing process is not located at its central fulcrum. This can easily lead to uneven deformation of the supporting structure under the eccentric force, which can affect the fit accuracy between the male and female molds, reduce the quality of the injection molded product, and even shorten the service life of the injection molding equipment.

[0040] Based on the above problems, the utility model provides an eccentric structure injection mold assembly, which aims to provide additional support for the bearing structure of the eccentric structure mold, so that the overall force of the bearing structure during the mold closing process is more balanced, thereby reducing the deformation amount and improving the uniformity of the overall deformation degree.

[0041] See also Figure 1 and Figure 2 The eccentric structure injection mold assembly provided by the embodiment of the utility model includes:

[0042] A first support plate 1;

[0043] A second support plate 2;

[0044] A first mold body 3 is eccentrically arranged on a side of the first support plate 1 facing the second support plate 2;

[0045] The second mold body 4 is eccentrically arranged on the side of the second support plate 2 facing the first support plate 1;

[0046] The bearing assembly 5 is arranged on the first support plate 1 and / or the second support plate 2;

[0047] When the first support plate 1 and the second support plate 2 approach each other along the first path and drive the first mold body 3 and the second mold body 4 to close the mold, the bearing assembly 5 is used to form an abutment and limiting effect between the first support plate 1 and the second support plate 2.

[0048] In this embodiment, one of the first mold body 3 and the second mold body 4 is a male mold, and the other of the first mold body 3 and the second mold body 4 is a female mold; the first mold body 3 is eccentrically arranged on the first support plate 1, and the first support plate 1 constitutes the basic bearing structure of the first mold body 3; the second mold body 4 is eccentrically arranged on the second support plate 2, and the second support plate 2 constitutes the basic bearing structure of the second mold body 4.

[0049] The bearing assembly 5 may include one or more columnar members, block members and other irregularly shaped parts; the bearing assembly 5 can be connected to the first support plate 1, or connected to the second support plate 2 by means of threaded connection, welding, snap connection, etc., or divided into two groups and connected to the first support plate 1 and the second support plate 2 respectively; the bearing assembly 5 is located between the first support plate 1 and the second support plate 2, and the bearing assembly 5 is spaced apart from the first mold body 3 and the second mold body 4 on a plane perpendicular to the mold closing direction.

[0050] During the mold closing process, driven by a hydraulic, pneumatic, or electrical drive device, the first support plate 1 and the second support plate 2 approach each other, ultimately pressing the first mold body 3 and the second mold body 4 together, so that the cavity of the first mold body 3 and the cavity of the second mold body 4 form a complete injection mold cavity. When the first mold body 3 and the second mold body 4 are completely closed, the supporting component 5 will also abut between the first support plate 1 and the second support plate 2, forming an additional support role, thereby preventing the first support plate 1 and the second support plate 2 in the area where the supporting component 5 is located from deforming in the direction of approaching each other, thereby balancing the force applied to each part of the first support plate 1 and the second support plate 2, making the overall force applied to the first support plate 1 and the second support plate 2 more balanced during the mold closing process, thereby reducing the deformation amount and improving the uniformity of the overall deformation degree, thereby reducing the adverse effects of uneven deformation on the matching accuracy between the first mold body 3 and the second mold body 4, improving the qualified rate of injection molded products, and extending the service life of the injection molding equipment.

[0051] Among them, when the bearing assembly 5 is only arranged on the first support plate 1, during the mold closing process, the bearing assembly 5 will abut against the second support plate 2; when the bearing assembly 5 is only arranged on the second support plate 2, during the mold closing process, the bearing assembly 5 will abut against the first support plate 1; when the bearing assembly 5 is divided into two groups and is respectively arranged on the first support plate 1 and the second support plate 2, during the mold closing process, the bearing assembly 5 on the first support plate 1 can abut against the second support plate 2, the bearing assembly 5 on the second support plate 2 can abut against the first support plate 1, and the bearing assembly 5 on the first support plate 1 can also abut against the bearing assembly 5 on the second support plate 2; when the bearing assembly 5 on the first support plate 1 abuts against the bearing assembly 5 on the second support plate 2, it can be ensured that the abutting surface is located on the bearing assembly 5, thereby reducing the degree of wear on the surfaces of the first support plate 1 and the second support plate 2, thereby extending the service life of the first support plate 1 and the second support plate 2.

[0052] It can be understood that in order to achieve the above-mentioned auxiliary support effect, under ideal circumstances, when the bearing assembly 5 is only arranged on the first support plate 1 or the second support plate 2, the size of the bearing assembly 5 in the mold closing direction should be equal to the relative distance between the first support plate 1 and the second support plate 2 when the mold is closed; when the bearing assembly 5 is divided into two groups and is respectively arranged on the first support plate 1 and the second support plate 2, the sum of the sizes of the two groups of bearing assemblies 5 abutting each other in the mold closing direction should be equal to the relative distance between the first support plate 1 and the second support plate 2 when the mold is closed.

[0053] Optionally, refer to Figure 1 and Figure 2 The eccentric structure injection mold assembly includes at least two bearing assemblies 5, and the at least two bearing assemblies 5 are arranged around the first mold body 3 and the second mold body 4 at intervals.

[0054] By providing at least two bearing assemblies 5 around the first mold body 3 and the second mold body 4, auxiliary support can be formed in multiple circumferential regions, thereby further improving the overall force balance and further improving the uniformity of the overall deformation of the first support plate 1 and the second support plate 2.

[0055] Among them, since the first mold body 3 and the second mold body 4 are eccentrically arranged on the first support plate 1 and the second support plate 2, in order to balance the reverse force exerted on the first support plate 1 and the second support plate 2 during the mold closing process, the specific placement position and placement quantity of the bearing component 5 can be set according to the deformation of the first support plate 1 and the second support plate 2, so that the force magnitude and deformation degree of the first support plate 1 and the second support plate 2 are more balanced.

[0056] Optionally, refer to Figure 1 and Figure 2The bearing component 5 is extended along the first path, and one end of the bearing component 5 is connected to the first support plate 1 and / or the second support plate 2; the eccentric structure injection mold assembly also includes a distance compensation member 6, which is detachably connected to the other end of the bearing component 5. The distance compensation member 6 is used to raise the other end of the bearing component 5 on the first path.

[0057] When injection molding different products, it is necessary to replace different injection molds (that is, replace different first mold bodies 3 and second mold bodies 4). Since the thicknesses of different first mold bodies 3 and second mold bodies 4 are different (specifically referring to the total thickness of the mold after the first mold body 3 and the second mold body 4 are closed), it is necessary to adaptively adjust the support length of the supporting component 5 along the first path (that is, the closing direction) to ensure that the size of the supporting component 5 in the closing direction is equal to the relative distance between the first support plate 1 and the second support plate 2 when the mold is closed, or to ensure that the two are within an acceptable deviation range.

[0058] Based on the above requirements, this embodiment provides a distance compensating member 6 on the supporting assembly 5. This allows the thickness of the distance compensating member 6 to act as a cushion to raise the supporting assembly 5, thereby changing the support length of the supporting assembly 5 along the first path (i.e., the mold closing direction). Specifically, when the supporting assembly 5 is provided only on the first support plate 1, the distance compensating member 6 directly abuts the second support plate 2 during mold closing. When the supporting assembly 5 is provided only on the second support plate 2, the distance compensating member 6 directly abuts the first support plate 1 during mold closing. When the supporting assembly 5 is divided into two groups and provided on the first support plate 1 and the second support plate 2, respectively, the distance compensating member 6 can be provided on either or both groups of the supporting assembly 5. During mold closing, the distance compensating member 6 on the first support plate 1 can directly abut the second support plate 2 or the distance compensating member 6 on the second support plate 2, and the distance compensating member 6 on the second support plate 2 can also directly abut the first support plate 1 or the distance compensating member 6 on the first support plate 1.

[0059] The distance compensating member 6 can be configured as any structure with a certain thickness, such as a sheet or block. Preferably, the distance compensating member 6 is an adjustable spacer, whose cross-sectional shape matches that of the support assembly 5. In practice, different numbers of distance compensating members 6 can be stacked on the support assembly 5 to adjust the support length of the support assembly 5 along the first path (i.e., the mold closing direction) to meet the auxiliary support requirements during mold closing.

[0060] Optionally, refer to Figure 1 and Figure 2 , the distance compensation member 6 is threadedly connected to the other end of the load-bearing component 5; the distance compensation member 6 is used to be screwed forward or reversely relative to the load-bearing component 5 to adjust the height difference of the distance compensation member 6 at the other end of the load-bearing component 5.

[0061] When the distance compensator 6 is threaded onto the carrier assembly 5, the distance it raises on the carrier assembly 5 can be adjusted linearly and in real time by screwing the distance compensator 6, thereby achieving real-time, linear adjustment of the support length of the carrier assembly 5 along the first path (i.e., the mold closing direction). This adjustment scheme allows the support length of the carrier assembly 5 to be more accurately adapted to injection molds of varying thicknesses. It is particularly suitable for situations where the thickness difference between two injection molds is minimal and the ideal support length cannot be accurately achieved by adding or removing the distance compensator 6.

[0062] Optionally, refer to Figure 1 and Figure 2 The eccentric structure injection mold assembly further includes a fastener 7 ; the fastener 7 is used to connect with the bearing assembly 5 and the distance compensation member 6 to prevent the distance compensation member 6 from rotating relative to the bearing assembly 5 .

[0063] Based on the scheme of adjusting the support length by screwing the distance compensation member 6 in the previous embodiment, when the distance compensation member 6 is screwed to the preset position, the support component 5 and the distance compensation member 6 can be locked by the fastener 7 to prevent the distance compensation member 6 from subsequently rotating relative to the support component 5 under the action of external force, thereby causing deviation in the support length.

[0064] Specifically, the fastener 7 can be any structure that can fix two devices, such as a pin, a buckle, etc. Figure 2 As shown, a threaded through hole connected to the load-bearing component 5 is provided on the distance compensation member 6, and the middle part of the fastener 7 is threadedly connected to the threaded through hole; when the distance compensation member 6 is screwed to a preset position relative to the load-bearing component 5, the fastener 7 can be screwed so that one end of the fastener 7 abuts against the load-bearing component 5, so that the relative fixation between the distance compensation member 6 and the load-bearing component 5 can be achieved through the abutment action of the fastener 7.

[0065] Optionally, refer to Figure 1 and Figure 2 At least two screw-assisting holes 62 are circumferentially spaced apart on the distance compensation member 6 .

[0066] During the commissioning phase before injection molding, the first and second mold bodies 3 and 4 are first closed, and then the distance compensator 6 is adjusted until it abuts. This ensures that the support length of the support assembly 5 is equal to the relative distance between the first support plate 1 and the second support plate 2 when the mold is closed. However, after the first and second mold bodies 3 and 4 are closed, the space around the support assembly 5 is relatively narrow, making it difficult for the operator to insert a standard wrench into the distance compensator 6 and tighten it.

[0067] Based on the above problems, this embodiment opens at least two screw-assisting holes 62 on the distance compensator 6 at circumferential intervals, so that the operator can insert a stick-like structure with a smaller diameter (such as one end of an Allen wrench) into the corresponding screw-assisting hole 62, thereby rotating the stick-like structure around the central axis of the distance compensator 6 in a relatively narrow space to drive the distance compensator 6 to complete the screwing action.

[0068] Optionally, refer to Figure 1 and Figure 2 The bearing assembly 5 includes a first bearing member 51 and a second bearing member 52. The first bearing member 51 is arranged on the first support plate 1, and the second bearing member 52 is arranged on the second support plate 2; the first bearing member 51 is provided with a boss portion 511, and the second bearing member 52 is provided with a cavity portion 521; the boss portion 511 is used to be inserted and matched in the cavity portion 521 when the first mold body 3 and the second mold body 4 are closed.

[0069] Specifically, when a first carrier 51 is provided on the first support plate 1 and a second carrier 52 is provided on the second support plate 2, a boss portion 511 is provided on one end of the first carrier 51 facing the second carrier 52, and a cavity portion 521 is provided on one end of the second carrier 52 facing the first carrier 51. During the mold closing process, when the first carrier 51 and the second carrier 52 abut against each other, the boss portion 511 will be inserted and fitted into the cavity portion 521, which can play a certain limiting role between the first carrier 51 and the second carrier 52, ensuring that the first carrier 51 and the second carrier 52 can complete the abutment more accurately and reliably along the mold closing direction, and at the same time, can prevent the first carrier 51 and the second carrier 52 from relative displacement after the abutment is completed. Among them, the boss portion 511 can be set as a cylindrical protruding structure, and the cavity portion 521 can be set as a cylindrical recessed structure.

[0070] Preferably, the height of the boss portion 511 is smaller than the depth of the cavity portion 521 , so as to prevent the boss portion 511 and the cavity portion 521 from directly bearing the pressing force during mold closing.

[0071] Optionally, refer to Figure 1 and Figure 2 The bearing assembly 5 includes a first bearing member 51 and a second bearing member 52. One end of the first bearing member 51 is connected to the first support plate 1, and the other end of the first bearing member 51 is provided with a boss portion 511. One end of the second bearing member 52 is connected to the second support plate 2, and the other end of the second bearing member 52 is provided with a cavity portion 521. The boss portion 511 is used to be inserted into the cavity portion 521 when the first mold body 3 and the second mold body 4 are closed.

[0072] The distance compensating member 6 is threadedly connected to the other end of the first supporting member 51 and slides along the first path on the boss portion 511 . The distance compensating member 6 is used to be screwed relative to the first supporting member 51 to move closer to or away from the second supporting member 52 .

[0073] When the first carrier 51 is provided with the distance compensation member 6 with a threaded connection in the above embodiment, the boss portion 511 can be used to guide the distance compensation member 6 to ensure that the distance compensation member 6 can always move stably along the first path (i.e., the mold closing direction) during the screwing process, and radial deflection of the distance compensation member 6 during the screwing process due to deviations in the threaded fit can be avoided, so that the abutting surface of the distance compensation member 6 (i.e., the surface abutting against the second carrier 52 during mold closing) can always remain parallel to the abutting surface of the second carrier 52 (i.e., the surface abutting against the distance compensation member 6 during mold closing).

[0074] Specifically, a guide hole 61 can be opened on the distance compensation part 6 along the first path (i.e., the mold closing direction), and the boss portion 511 can be set as a cylindrical protrusion structure and passed through the guide hole 61. In this way, the boss portion 511 can guide the distance compensation part 6 by cooperating with the axial hole between the boss portion 511 and the guide hole 61.

[0075] Optionally, refer to Figure 1 and Figure 2 The eccentric structure injection mold assembly further includes a buffer layer 8, which is disposed on the bearing assembly 5; when the bearing assembly 5 is abutted and limited between the first support plate 1 and the second support plate 2, the buffer layer 8 is used to form a buffering effect.

[0076] The buffering effect of the buffer layer 8 during the mold closing process can reduce the impact damage to the load-bearing component 5 during the abutment and limiting, thereby extending the service life of the load-bearing component 5. The buffer layer 8 can be configured as a flexible structural layer such as a rubber layer, a fiber layer, etc., which is not limited here.

[0077] Optionally, refer to Figure 1 and Figure 2 At least two first mounting positions (not shown in the figure) are arranged on the first support plate 1 around the first mold body 3, and the bearing component 5 is connected to at least one of the first mounting positions.

[0078] Optionally, refer to Figure 1 and Figure 2 At least two second mounting positions (not shown in the figure) are arranged on the second support plate 2 around the second mold body 4, and the bearing component 5 is connected to at least one of the second mounting positions.

[0079] Specifically, taking the example of the load-bearing component 5 being fixed to the first support plate 1 by means of a locking connection of the threaded fasteners 7, the first connection holes on the first support plate 1 for inserting the threaded fasteners 7 can be arranged in multiple groups at intervals around the first mold body 3, and each group of first connection holes constitutes a first mounting position. In this way, the load-bearing component 5 can be flexibly connected to different first mounting positions according to the deformation conditions of various locations on the first support plate 1. In this way, auxiliary support can be provided to the areas on the first support plate 1 that are prone to deformation in a more targeted manner, thereby making the force and deformation degree of various locations on the first support plate 1 more balanced. Among them, the first connection holes in the above-mentioned first mounting positions can also be set as waist-shaped holes, so that the placement position of the load-bearing component 5 can be linearly adjusted within a certain range.

[0080] Similarly, taking the example of the load-bearing assembly 5 being fixed to the second support plate 2 by means of a locking connection of the threaded fasteners 7, the second connection holes on the second support plate 2 for inserting the threaded fasteners 7 can be arranged in multiple groups spaced around the second mold body 4, with each group of second connection holes constituting a second mounting position. In this way, the load-bearing assembly 5 can be flexibly connected to different second mounting positions according to the deformation amount at various locations on the second support plate 2. In this way, auxiliary support can be provided to areas on the second support plate 2 that are prone to deformation in a more targeted manner, thereby making the force and deformation degree at various locations on the second support plate 2 more balanced. Among them, the second connection holes in the above-mentioned second mounting positions can also be set as waist-shaped holes, so that the placement position of the load-bearing assembly 5 can be linearly adjusted within a certain range.

[0081] Optionally, refer to Figure 1 and Figure 2 A first pressure sensor 9 is provided on the side of the first support plate 1 facing away from the second support plate 2. This first pressure sensor 9 is used to obtain the real-time pressure applied to the first support plate 1 during the closing of the first mold body 3 and the second mold body 4. The provision of this first pressure sensor 9 allows the operator to intuitively determine the pressure applied to various locations on the first support plate 1 after the mold is closed. This facilitates the determination of the appropriate placement of the support assembly 5 and allows for more targeted auxiliary support of areas of the first support plate 1 prone to deformation. One or more first pressure sensors 9 can be provided as needed.

[0082] Optionally, refer to Figure 1 and Figure 2A second pressure sensor 10 is provided on the side of the second support plate 2 facing away from the first support plate 1. This second pressure sensor 10 is used to obtain the real-time pressure value exerted on the second support plate 2 when the first mold body 3 and the second mold body 4 are closed. The provision of this second pressure sensor 10 allows the operator to intuitively determine the pressure exerted on various locations on the second support plate 2 after the mold is closed, thereby more conveniently determining the placement of the support assembly 5 and providing more targeted auxiliary support to areas of the second support plate 2 that are prone to deformation. One or more second pressure sensors 10 can be provided based on actual needs.
