Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a tilting ejection mechanism and a tilting ejection mold. Background Art

[0002] In the manufacturing process of plastic products, the demolding direction of the product is generally consistent with the mold opening direction. However, when the product has an inclined hook, if the demolding method is used in the same direction as the mold opening, it will interfere with the hook and prevent normal demolding. Therefore, the relevant technology usually adopts a tilted ejector mechanism to avoid this problem by using an inclined ejector mechanism. In the current tilted ejector mechanism, the ejector rod and the ejector seat are in flat contact. As the ejector rod slides in the ejector seat, the ejector rod and the ejector seat will gradually wear out, and even cause the ejector rod and the ejector seat to become stuck. The probability of this phenomenon gradually increases with the use of the ejector mechanism. In severe cases, it may cause the ejector seat or the ejector rod to crack and be damaged.

[0034] The present invention is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted under different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0035] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0036] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0037] In order to solve the problem in the prior art that the sliding between the inclined ejector rod and the inclined ejector seat is prone to wear and even jamming, thereby causing the inclined ejector rod and the inclined ejector seat to crack and be damaged, in an embodiment of the utility model, a inclined ejector mechanism and an inclined ejector mold are provided. By configuring the contact between the limit member and the groove wall of the guide groove to be line contact or point contact, the contact area is reduced compared to the surface contact, and the wear and / or jamming caused by excessive contact between the limit member and the guide groove is effectively avoided, thereby reducing the probability of damage to the inclined ejector rod and the inclined ejector seat and improving the durability of the inclined ejector mechanism.

[0038] Please refer to Figures 1 to 3 As shown, the specific composition structure of the inclined lift mechanism 1 provided in the embodiment of the present application includes:

[0039] The inclined top seat 2 has a guide groove 21 extending along the first direction, and the guide groove 21 has an opening extending along the first direction;

[0040] The inclined ejector rod 3 has a first end 31 and a second end 32 arranged opposite to each other along its length direction; the length direction of the inclined ejector rod 3 intersects with the first direction; the inclined ejector rod 3 is arranged through the opening of the guide groove 21;

[0041] The limiting member 4 is provided at the first end 31 ; the limiting member 4 is movably provided in the guide groove 21 and forms a line contact or a point contact with the groove wall of the guide groove 21 ;

[0042] The molding member 5 is provided at the second end 32; the molding member 5 is used as a product mold to perform injection molding on the product;

[0043] The lift seat 2 can move along the second direction to drive the limiting member 4 to move in the guide groove 21, and drive the lift rod 3 to move along the length direction through the limiting member 4; the second direction intersects with the first direction.

[0044] The inclined ejector mechanism 1 is a mechanism used in mold design for forming the barb of a molded product. Its characteristic is that it can be demoulded in an oblique direction, thereby avoiding damage to the barb structure of the molded product.

[0045] The lift mechanism 1 comprises a lift seat 2, which is formed with a guide slot 21 extending in a first direction. The guide slot 21 accommodates a lift rod 3, allowing it to move within the space provided by the slot, thereby limiting the direction of movement of the lift rod 3. The lift seat 2 itself is designed to move, and this movement drives the lift rod 3 to move accordingly, thereby enabling operations such as mold closing and demolding.

[0046] The components of the lift mechanism 1 also include a lift rod 3, wherein the lift rod 3 has two ends along its length direction, namely a first end 31 and a second end 32. The first end 31 is arranged close to the lift seat 2, and the second end 32 is arranged away from the lift seat 2. The length direction of the lift rod 3 intersects with the first direction of extension of the lift seat 2. According to different mold requirements, the angle between the first direction and the length direction can also be set accordingly. Generally, a certain angle is formed between the length direction of the lift rod 3 and the normal direction of the first direction. When moving, the lift rod 3 will translate along its length direction. At the same time, the lift rod 3 will translate along the first direction in the guide groove 21 relative to the lift seat 2. Therefore, the movement of the lift rod 3 is actually a composite result of translation along the length direction and translation along the first direction.

[0047] In order to facilitate the translation of the inclined ejector rod 3 in the guide groove 21, reduce the contact area between the inclined ejector rod 3 and the inclined ejector seat 2 to reduce the wear between the inclined ejector rod 3 and the inclined ejector seat 2, and prevent the inclined ejector rod 3 and the inclined ejector seat 2 from getting stuck, the inclined ejector mechanism 1 in the embodiment of the present application also includes a limiter 4, which is provided at the first end 31 of the inclined ejector rod 3, that is, the end of the inclined ejector rod 3 close to and located in the guide groove 21. The inclined ejector rod 3 forms a contact connection with the inclined ejector seat 2 through the limiter 4, rather than the inclined ejector rod 3 directly contacting the inclined ejector seat 2. Moreover, the contact formed between the limiter 4 and the groove wall of the guide groove 21 is line contact or point contact. Compared with surface contact, the contact area of ​​line contact and point contact is greatly reduced, the wear between the limiter 4 and the inclined ejector seat 2 is improved, and the possibility of the limiter 4 and the inclined ejector rod 3 getting stuck is reduced.

[0048] The molding member 5 is positioned at the second end 32 of the lifter 3. The molding member 5 forms a mold for forming the product. During demolding, the molding member tilts as the lifter 3 moves, avoiding damage to the product's barbs and other structures. The specific demolding angle can be determined based on the product's design.

[0049] The specific operation mode of the tilting mechanism 1 in the embodiment of the present application is that the tilting seat 2 can move along the second direction. Due to the movement of the tilting seat 2, it drives the limiter 4 located in the guide groove 21 to move in the corresponding direction, that is, the limiter 4 will also move in the second direction; and the limiter 4 is fixed to the first end 31 of the tilting rod 3, so the tilting rod 3 will also move due to the movement of the tilting seat 2; the movement of the tilting rod 3 is decomposed into the longitudinal direction extending along the guide hole 61 and the first direction extending along the guide groove 21, thereby achieving the purpose of demolding in the inclined direction. During the movement, the contact between the limiter 4 and the groove wall of the guide groove 21 is point contact or line contact, and the contact area is small. Therefore, the limiter 4 and the guide groove 21 are not easy to wear or get stuck during movement, thereby improving the service life of the tilting mechanism 1. Among them, the second direction intersects with the first direction and also intersects with the length direction of the inclined ejector rod 3. According to the extension direction of the guide groove 21 of the conventional inclined ejector seat 2, the second direction is generally perpendicular to the first direction; or, when the guide groove 21 provided on the inclined ejector seat 2 is irregular, the second direction can also be other directions that do not overlap with the first direction.

[0050] In some optional embodiments, please continue to refer to Figure 5 In order to achieve point contact or line contact between the stopper 4 and the groove wall of the guide groove 21, in the embodiment of the present application, the cross-sectional shape of the stopper 4 can be specifically circular, so that line contact or point contact is formed between the stopper 4 and the groove wall of the guide groove 21. Since the cross-sectional shape of the stopper 4 is circular, the contact between the circle and the groove wall of the guide groove 21 is equivalent to the groove wall of the guide groove 21 being tangent to the edge of the circle, thereby achieving the purpose of line contact or point contact between the stopper 4 and the groove wall of the guide groove 21.

[0051] In some optional embodiments, please continue to refer to Figure 5 To form a circular cross-sectional shape, the outer contour of the stopper 4 can be cylindrical, so that the stopper 4 forms a linear contact with the wall of the guide groove 21; or the outer contour of the stopper 4 can be spherical, so that the stopper 4 forms a point contact with the wall of the guide groove 21. In addition, the outer contour of the stopper 4 can also be an ellipsoid, a disc, etc.

[0052] In some alternative embodiments, please refer to Figure 4 and Figure 5To accommodate the stopper 4, the guide groove 21 may include a first cavity 22 and a second cavity 23, the openings of which are arranged opposite each other and interconnected. Two stoppers 4 are provided, one on each side of the first end 31 and one within each of the first cavity 22 and the second cavity 23, respectively, and form line or point contact with the walls of the corresponding first cavity 22 and the second cavity 23. The first cavity 22 and the second cavity 23 are arranged opposite each other, with their openings facing each other. The first cavity 22 and the second cavity 23, together with the gap therebetween, form the guide groove 21. Two stoppers 4 are provided, corresponding to the first cavity 22 and the second cavity 23: one stopper 4 is provided in the first cavity 22 and one in the second cavity 23. The stoppers 4 can move along the space provided by the first cavity 22 and the second cavity 23. Since the openings of the first groove cavity 22 and the second groove cavity 23 are arranged relative to each other, the limit member 4 can be limited at the upper and lower cavity walls of the first groove cavity 22, and the contact formed between the limit member 4 and the cavity walls of the first groove cavity 22 and the second groove cavity 23 is point contact or surface contact, so as to reduce wear and reduce the possibility of jamming between the limit member 4 and the guide groove 21.

[0053] In some optional embodiments, please continue to refer to Figure 4 In order to prevent the first end 31 of the inclined ejector rod 3 and the limit member 4 from falling off from the guide groove 21, the inclined ejector seat 2 has a bottom wall 25, a first side wall 26 and a second side wall 27 arranged oppositely, and a first top wall 28 and a second top wall 29 arranged oppositely; the first side wall 26 and the second side wall 27 are respectively arranged on the two side edges of the bottom wall 25 along the first direction and extend along the second direction; the first top wall 28 is fixedly arranged at the end of the first side wall 26 away from the bottom wall 25, and the second top wall 29 is fixedly arranged at the end of the second side wall 27 away from the bottom wall 25, and the first top wall 28 and the second top wall 29 extend toward each other to form an opening of the guide groove 21; the bottom wall 25, the first side wall 26 and the first top wall 28 enclose a first groove cavity 22, and the bottom wall 25, the second side wall 27 and the second top wall 29 enclose a second groove cavity 23. Under this structure, when the limit member 4 is set in the first groove cavity 22 and the second groove cavity 23, the top of the limit member 4 is limited by the first top wall 28 and the second top wall 29 respectively, thereby preventing the limit member 4 and even the inclined push rod 3 from detaching from the guide groove 21.

[0054] In some optional embodiments, please continue to refer to Figure 4In order to prevent the inside of the guide groove 21 from directly contacting the lift rod 3, thereby causing wear and jamming of the lift rod 3, the guide groove 21 may further include an avoidance groove 24. The avoidance groove 24 is connected and arranged between the first groove cavity 22 and the second groove cavity 23, and is located on the side away from the opening of the guide groove 21. The avoidance groove 24 is used to accommodate the first end 31, and a preset gap is provided between the groove wall of the avoidance groove 24 and the first end 31. In other words, the avoidance groove 24 can be provided at the bottom of the guide groove 21. Based on the structure of the avoidance groove 24, the lift rod 3 can be prevented from directly contacting the groove wall of the guide groove 21, thereby preventing direct contact between the lift seat 2 and the lift rod 3.

[0055] In some alternative embodiments, please refer to Figure 6 In order to form a connection between the limiter 4 and the lift rod 3, the lift mechanism 1 may further include a fixed shaft 7, which is passed through the limiter 4 and fixedly connected to the lift rod 3, so that the limiter 4 and the lift rod 3 are rotatably connected. The limiter 4 is provided with a corresponding connection hole. By passing the fixed shaft 7 through the connection hole and fixing the fixed shaft 7 to the lift rod 3, the limiter 4 can be restrictedly connected to the lift rod 3, thereby realizing the connection between the limiter 4 and the lift rod 3. Specifically, the fixed shaft 7 can be a connector such as a pin or a bolt, and can form a threaded fit or a shaft-hole fit with the limiter 4.

[0056] In some optional embodiments, please continue to refer to Figure 6 To further reduce the friction between the stopper 4 and the inclined ejector seat 2, the stopper 4 can be rotatably sleeved on the fixed shaft 7, allowing the stopper 4 to rotate relative to the inclined ejector rod 3. In other words, the fixed shaft 7 can serve as the rotation axis connecting the stopper 4 and the inclined ejector rod 3. The stopper 4 can rotate relative to the inclined ejector rod 3 with the rotation axis as the rotation center, thereby achieving rotational contact between the stopper 4 and the inclined ejector seat 2. Compared to sliding contact, rotational contact greatly reduces the friction, thereby further reducing the possibility of contact wear between the stopper 4 and the inclined ejector seat 2, and further reducing the possibility of the stopper 4 and the inclined ejector seat 2 getting stuck.

[0057] In some alternative embodiments, please refer to Figure 3 To facilitate placement of the lift rod 3 and the stopper 4 into the guide groove 21, at least one of the two ends of the guide groove 21 along the first direction is provided with a mounting opening 20 that communicates with the guide groove 21. The shape and size of the mounting opening 20 can accommodate the first end 31 of the lift rod 3 and the stopper 4 inserted into the guide groove 21, thereby allowing the stopper 4 and the first end 31 of the lift rod 3 to be located within the guide groove 21, thereby allowing the stopper 4 and the lift rod 3 to move within the guide groove 21. The mounting opening 20 can be provided at both ends of the mounting opening 20 of the lift seat 2.

[0058] In an embodiment of the present application, a tilting mechanism 1 is provided. Since the contact between the limiting member 4 and the groove wall of the guide groove 21 is point or line contact, the contact area is reduced compared to surface contact, and wear or jamming caused by excessive contact between the limiting member 4 and the guide groove 21 is effectively avoided, thereby reducing the probability of damage to the tilting rod 3 and the tilting seat 2, and improving the durability of the tilting mechanism 1.

[0059] The present application also provides a tilting top mold, please refer to Figures 7 to 9 , including a support frame 92, an ejection mechanism 8, a fixed mold member 91 and the above-mentioned inclined ejection mechanism 1;

[0060] The two ends of the support frame 92 along the second direction are respectively connected to the fixed mold 91 and the ejection mechanism 8;

[0061] The fixed mold member 91 has a first guide hole 93 extending along the length direction. The inclined ejector rod 3 is disposed in the first guide hole 93, with the first end 31 and the second end 32 respectively located at the two ends of the first guide hole 93. The fixed mold member 91 and the forming member 5 cooperate with each other to form a mold for the product.

[0062] The ejection mechanism 8 is supported on the inclined ejector seat 2; the ejection mechanism 8 is used to eject the inclined ejector seat 2 along the second direction to drive the limit member 4 to drive the inclined ejector rod 3 to move along the length direction, so that the molded part 5 and the fixed mold part 91 are separated from each other.

[0063] The inclined top mold in the embodiment of the present application is used for injection molding of plastic products; wherein, the mold used for molding includes a fixed mold part 91 and a molding part 5 in the inclined top mechanism 1 in the above embodiment, wherein the inclined top mechanism 1 may include one or more, and each molding part 5 cooperates with the fixed mold part 91 to form the mold required for product molding.

[0064] After the injection molding process completes the product formation, during the demolding process, in the embodiment of the present application, an ejection mechanism 8 and a tilting mechanism 1 are provided. The ejection mechanism 8 forces the tilting seat 2 in the tilting mechanism 1 to move in the second direction, and the tilting seat 2 correspondingly drives the tilting rod 3 disposed in the guide groove 21 to move in the length direction. At the same time, the tilting rod 3 also moves in the guide groove 21 in the first direction. At this time, the molded part 5 is separated from the fixed mold part 91, thereby achieving the purpose of demolding the product. The fixed mold part 91 refers to the mold that is fixed in position during the product injection molding process.

[0065] In order to limit the movement direction of the lifter 3 and allow it to move along its length, the lifter mechanism 1 may further include a guide member 6. The guide member 6 is disposed on a side of the fixed mold 91 near the ejection mechanism 8 and is fixedly connected to the fixed mold 91. The guide member 6 has a second guide hole 61 extending along the length of the lifter 3. The guide member 6 is sleeved onto the lifter 3 through the second guide hole 61. Therefore, during movement, the lifter 3 moves within the space defined by the second guide hole 61, thereby preventing the lifter 3 from moving outside the direction defined by the second guide hole 61 and avoiding damage to the product during demolding. The same applies to the first guide hole 93 on the fixed mold 91. The interaction between the two can greatly enhance the guiding and limiting effect on the movement direction of the lifter 3.

[0066] In some optional embodiments, in order to smoothly perform the ejection operation on the inclined ejector seat 2, the ejection mechanism 8 may specifically include a base 81, a bottom plate assembly 82 and an ejector 83; the base 82 is fixedly connected to the support frame 92; the bottom plate assembly 82 is supported by the base 81 and is located between the base 81 and the fixed mold 91, and the bottom plate assembly 82 is fixedly connected to the inclined ejector seat 2; the base 81 has a connecting hole passing through along the second direction, and the ejector 83 is passed through the connecting hole and movably connected to the base 81, for ejecting the bottom plate assembly 82 and driving the inclined ejector seat 2 to drive the limiting member 4 to drive the inclined ejector rod 3 to move along the length direction, so that the molded part 5 and the fixed mold 91 are separated from each other. By moving the ejector 83 upward in the connecting hole, the bottom plate assembly 82 is pushed, and then the inclined ejector seat 2 fixedly connected to the bottom plate 82 is pushed, so that the inclined ejector seat 2 moves along the second direction, driving the inclined ejector rod 3 to move along its length direction, and at the same time moving along the first direction in the guide groove 21 to achieve demolding, as shown in FIG. Figure 9 shown.

[0067] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
