Description

Technical Field

[0001] This utility model belongs to the field of mold technology, specifically to a mold with an anti-collision structure. Background Technology

[0002] The mold consists of an upper cavity and a lower core, with the gap between them being the mold chamber. To facilitate demolding, a sliding cavity slider is installed inside the cavity. One end of the slider is attached to the mold chamber. When demolding is required, the cavity slider is pushed, and its end pushes the product away from the cavity.

[0003] When the front mold is in an abnormal state, the ejector in the cavity and the limiting cavity will collide, causing the cavity slider to fail to retract, which will damage the core and the mold, thus damaging the core. Utility Model Content

[0004] The purpose of this invention is to provide a mold with an anti-collision structure to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is as follows: A mold with an anti-collision structure includes an upper mold and a lower mold. At least one pusher is movably inserted into the upper mold near the lower mold. The pusher has a protrusion on the side near the lower mold. The lower mold has a limiting cavity. A spring block is elastically connected to the limiting cavity near the upper mold. The lower mold has a groove perpendicular to the spring block. The groove is connected to one side of the limiting cavity. The pusher can slide relative to the groove. When the protrusion abuts against the spring block, the spring block elastically retracts, causing the protrusion to enter the side abutting the limiting cavity. At this time, the spring block resets and abuts against the side of the protrusion.

[0006] Preferably, the rebound block has a guide slope on the side away from the limiting cavity, which facilitates the timely rebound of the rebound block when the protrusion squeezes it, thus reducing wear.

[0007] Preferably, the upper mold has a through hole, and the pusher has a corresponding circular hole, with the axis of the circular hole and the axis of the through hole at the same horizontal position.

[0008] Preferably, the upper mold is provided with a limiting member on one side of the pusher via an elastic connection, and the pusher is provided with multiple corresponding positioning grooves on the side near the limiting member. When the pusher moves to the corresponding position, the limiting member can engage with a positioning groove.

[0009] Preferably, the lower mold is provided with a detachable first positioning plate on one side of the spring block, and a first spring is provided between the spring block and the first positioning plate, with one side of the first spring abutting against the first positioning plate.

[0010] Preferably, the upper mold is provided with a detachable second positioning plate on one side of the limiting member, and a second spring is provided between the limiting member and the second positioning plate, with one side of the second spring abutting against the second positioning plate.

[0011] Preferably, the positioning groove has rounded corners, and the limiting member has a corresponding arc surface on the side that abuts against the positioning groove.

[0012] Preferably, the outer side of the upper mold is provided with multiple rounded corners.

[0013] Preferably, the upper mold is an integral structure.

[0014] Preferably, the pusher is located on the side of the lower die that is not higher than the outer side of the upper die.

[0015] Compared with the prior art, this utility model provides a mold with an anti-collision structure, which has the following advantages: When the front mold is in an abnormal state, in order to prevent the ejector from impacting the limiting cavity and causing damage to the protrusion and the mold, an elastically connected spring block is set on the lower mold. When the protrusion hits the spring block, the spring block moves down and the protrusion enters the limiting cavity and abuts against one side of the limiting cavity, so that the ejector stops moving forward. To ensure its stability, the spring block is elastically reset to its initial state, and at this time the spring block abuts against the side of the protrusion away from the limiting cavity.

[0028] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0029] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0030] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0033] like Figures 1 to 5 As shown, the device includes an upper mold 1 and a lower mold 2. At least one pusher 11 is movably inserted into the upper mold 1 near the lower mold 2. The pusher 11 has a protrusion 111 near the lower mold 2. The lower mold 2 has a limiting cavity 21. A spring block 22 is elastically connected to the limiting cavity 21 near the upper mold 1. The lower mold 2 has a groove 23 perpendicular to the spring block 22. The groove 23 connects to one side of the limiting cavity 21. The pusher 11 can slide relative to the groove 23. When the protrusion 111 abuts against the spring block 22, the spring block 22 elastically retracts, causing the protrusion 111 to enter the side abutting against the limiting cavity 21. At this time, the spring block 22... Reset, abutting one side of the protrusion 111; when the front mold is in an abnormal state, in order to prevent the ejector 11 from impacting the limiting cavity 21 and causing damage to the protrusion 111 and the mold, a spring-loaded elastic block 22 is provided on the lower mold 2. When the protrusion 111 hits the spring-loaded block 22, the spring-loaded block 22 moves downward, and the protrusion 111 enters the limiting cavity 21 and abuts one side of the limiting cavity 21, so that the ejector 11 no longer moves forward. To ensure its stability, the spring-loaded block 22 is elastically reset to its initial state. At this time, the spring-loaded block 22 abuts the side of the protrusion 111 away from the limiting cavity 21, preventing the ejector 11 from moving back and forth relative to the upper mold 1; Figure 9 As shown, the upper mold is provided with two pushers 11, which are placed opposite each other.

[0034] like Figures 1 to 8As shown, the spring block 22 has a guide slope 221 on the side away from the limiting cavity 21, which facilitates the timely rebound of the spring block 22 when the protrusion 111 presses against it, reducing wear. The upper mold 1 has a through hole 12, and the pusher 11 has a corresponding circular hole 112. The axis of the circular hole 112 and the axis of the through hole 12 are at the same horizontal position, ensuring the stability of the fit between the pusher 11 and the upper mold 1. The upper mold 1 has a limiting member 13 elastically connected to the side of the pusher 11. The side of the pusher 11 near the limiting member 13 has multiple corresponding positioning grooves 113. When the pusher 11 moves to the corresponding position, the limiting member 13 can engage a positioning groove 113, which facilitates precise positioning of the pusher 11 and improves product reliability. The lower mold 2 is located on the side of the spring block 21. A detachable first positioning plate 25 is provided on one side of the upper mold 1. A first spring 24 is provided between the spring block 22 and the first positioning plate 25. The two ends of the first spring 24 abut against the spring block 22 and the first positioning plate 25 respectively. A detachable second positioning plate 14 is provided on one side of the upper mold 1 located on the limiting member 13. A second spring 15 is provided between the limiting member 13 and the second positioning plate 14. One side of the second spring 15 abuts against the second positioning plate 14. A rounded corner 114 is provided in the positioning groove 113. A corresponding arc surface 131 is provided on the side of the limiting member 13 that abuts against the positioning groove 113. Multiple arc corners 16 are provided on the outer side of the upper mold 1. The upper mold 1 is an integral structure. The side of the pusher 11 near the lower mold 2 is not higher than the outer side of the upper mold 1, which can reduce the wear of the pusher 11 by the lower mold 2.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
