[0001] The utility model belongs to the field of molds, and in particular relates to an inclined top parallel auxiliary mechanism for molds. Background Art

[0002] With the rapid development of the machinery industry, people pay more and more attention to the quality of products. Therefore, the smoothness and stability in the product molding process are closely related to the quality of the final product molding.

[0003] At present, in the process of molding products, the existing molds often use the method of extending the inclined ejector rod into the product cavity, so that the through hole on the product can be directly molded during the injection molding process. However, in the process of the moving block pushing the inclined ejector rod to move back and forth along its own inclined direction, due to the following Figure 1 When the moving block shown moves downward in the vertical direction, it is bound to exert a downward extrusion force on the inclined ejector rod, which may easily cause a jam between the inclined ejector rod and the fixed block, affecting the smoothness of the inclined ejector rod in molding the product or ejecting the product, and may also easily cause the inclined ejector rod to tilt and deviate, thereby affecting the molding quality of the product, thereby reducing the qualified rate of the product.

The tilting rod is movably inserted into the fixed block, so that when the moving block approaches or moves away from the fixed block, the tilting rod can reciprocate along its own tilting direction;

[0008] When the moving block approaches the fixed block, the lift rod can be clamped in the moving block in parallel with the auxiliary rod, so that the lift rod always reciprocates along its own tilting direction to prevent position interference between the lift rod and the fixed block.

[0011] In the above-mentioned inclined top parallel auxiliary mechanism for a mold, the clamping member includes:

[0012] A connecting block, detachably connected to the inclined ejector rod and the auxiliary rod;

[0013] A clamping block, with fixed shafts extending outwardly on both sides of the connecting block, the fixed shafts are rotatably connected to the clamping block, and the clamping block is movably clamped in the clamping groove, so that the inclined ejector rod and the auxiliary rod move back and forth synchronously in the clamping groove.

[0014] In the above-mentioned inclined top parallel auxiliary mechanism for a mold, a guide groove connected to the engaging groove is further provided in the moving block, and the auxiliary rod is movably arranged in the guide groove.

[0017] In the above-mentioned inclined ejector parallel auxiliary mechanism for a mold, a guide sleeve is arranged in the movable mold base, and the inclined ejector rod is movably inserted in the guide sleeve.

[0018] Compared with the prior art, the advantage of the utility model lies in that in the process of the moving block pushing the inclined ejector rod to move along its inclined direction, the auxiliary rod is synchronously and parallelly connected with the inclined ejector rod in the moving block, which effectively assists the inclined ejector rod to move back and forth along its own inclined direction.

[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0029] like Figure 1 to Figure 2 As shown, the utility model is a kind of inclined ejector parallel auxiliary mechanism for mold, comprising: a fixed block 1 arranged in a movable mold base; a moving block 2, which is movably arranged in the movable mold base, and the moving block 2 is movably clamped with an inclined ejector rod 3, and the inclined ejector rod 3 is movably inserted in the fixed block 1, so that when the moving block 2 approaches or moves away from the fixed block 1, the inclined ejector rod 3 can reciprocate along its own inclined direction; an auxiliary rod 4, which is movably clamped in the moving block 2 and is arranged parallel to the inclined ejector rod 3, one end of the auxiliary rod 4 is movably hinged on the fixed block 1, and the other end is movably hinged to the movable mold base; when the moving block 2 approaches the fixed block 1, the inclined ejector rod 3 can always reciprocate along its own inclined direction due to the auxiliary rod 4 being parallel to it and clamped in the moving block 2, so as to prevent the inclined ejector rod 3 from interfering with the fixed block 1 in position.

[0030] It is worth noting that the parallel auxiliary mechanism in this solution can be applied to a large angle inclined roof environment. Specifically, when the moving block 2 moves along Figure 1When the lifting rod 3 is lifted up, the lifting block 2 is lifted up, and the lifting rod 3 is lifted up, so that the lifting rod 3 can be lifted up and the lifting block 2 can be lifted up, and the lifting block 2 can be lifted up and the lifting block 2 can be lifted up, so that the lifting rod 3 can be lifted up and the lifting block 2 can be lifted up, and the lifting block 2 can be lifted up and the lifting block 3 can be lifted up, so that the lifting rod 3 can be lifted up and the lifting block 1 can be lifted up, and the lifting block 2 can be lifted up and the lifting block 3 can be lifted up, and the lifting block 2 can be lifted up and the lifting block 3 can be lifted up, and the lifting block 2 can be lifted up and the lifting block 3 can be lifted up, and the lifting block 3 ... Figure 2 The auxiliary rod 4 shown in the figure is arranged in a manner that both ends are movably connected, so that the auxiliary rod 4 and the inclined ejector rod 3 are always placed in parallel. The displacement generated by the auxiliary rod 4 to ensure parallelism with the inclined ejector rod 3 not only gives a certain pulling force to the fixed block 1, but also effectively assists the inclined ejector rod 3 to smoothly reciprocate along its own inclined direction, avoiding the stuck phenomenon between the inclined ejector rod 3 and the fixed block 1, which affects the smoothness and stability of the product molding or product ejection process; it should be noted that the pulling force when the auxiliary rod 4 moves leftward relative to the moving block 2 (that is, perpendicular to the direction of the auxiliary rod 4, relative to the direction of the auxiliary rod 4) Figure 2 The direction of the upper left tilt (not shown in the figure) can just match the extrusion force exerted by the inclined ejector rod 3 on the fixed block 1 (i.e., the direction perpendicular to the inclined ejector rod 3, relative to the Figure 2 The inclined direction along the lower right side (not shown in the figure) is offset to ensure that the fixed block 1 is in a stable posture relative to the movable mold base, while also providing a guarantee for the smoothness and stability of the inclined ejector rod 3 when it reciprocates along its own inclined direction to form or eject the product, which is beneficial to increase the overall structural strength of the inclined ejector parallel auxiliary mechanism, effectively ensuring the quality of the product after molding, and ensuring that the product can meet the customer's usage requirements.

[0031] The inclined ejector rod 3 and the auxiliary rod 4 are commonly connected with a clamping member 5 . Clamping grooves 20 are symmetrically arranged in the moving block 2 . The clamping member 5 is movably clamped in the clamping groove 20 .

[0032] like Figure 2 As shown, the clamping member 5 is connected to the inclined rod 3 and the auxiliary rod 4 at the same time. It is worth noting that the clamping member 5 and the auxiliary rod 4 and the inclined rod 3 are all connected in a movable sleeve manner, that is, when the moving block 2 is moved along the Figure 2 When moving vertically downward, the clamping member 5 can move along Figure 2The direction of the engaging groove 20 moves to the left, thereby pushing the inclined lift rod 3 to move downward along its own inclined direction. At the same time, the movable sleeve of the clamping piece 5 and the auxiliary rod 4 can be used to ensure the parallel movement of the auxiliary rod 4 and the inclined lift rod 3, and the pulling force of the fixed block 1 applied by the auxiliary rod 4 when moving can offset the squeezing force of the inclined lift rod 3 on the fixed block 1, further improving the smoothness and stability of the inclined lift rod 3 when performing the inclined lifting action.

[0033] Preferably, an inclined guide hole 10 is provided in the fixed block 1 in the present embodiment. When the movable block 2 moves downward to push the inclined ejector rod 3 to move, the inclined ejector rod 3 is movably inserted into the inclined guide hole 10, thereby providing a guiding and limiting effect when the inclined ejector rod 3 moves, thereby ensuring that the inclined ejector parallel auxiliary mechanism can smoothly eject the product.

[0034] The clamping member 5 includes: a connecting block 50, which is detachably connected to the inclined ejector rod 3 and the auxiliary rod 4; a clamping block 51, and fixed shafts 52 extend outwardly on both sides of the connecting block 50, and the fixed shafts 52 are rotatably connected to the clamping block 51. The clamping block 51 is movably clamped in the clamping groove 20, so that the inclined ejector rod 3 and the auxiliary rod 4 can move back and forth synchronously in the clamping groove 20.

[0035] Further reference Figure 2 In this solution, the inclined push rod 3 and the connecting block 50 can be connected by screws, screws and other connecting pieces, while the auxiliary rod 4 and the connecting block 50 are connected by a movable sleeve. Figure 2 When moving downward, it can push the locking block 51 to move leftward along the locking groove 20. By utilizing the rotation of the fixed shaft 52 on the connecting block 50 relative to the locking block 51 (that is, the movable hinged connection between the two), the inclined ejector rod 3 can move downward along its own inclined direction while ensuring that the auxiliary rod 4 and the inclined ejector rod 3 are synchronously swung relative to the locking block 51 and are still placed in a parallel posture. This not only ensures the pulling force on the fixed block 1, but also can utilize the auxiliary rod 4 to assist in guiding the inclined ejector rod 3 to reciprocate along its own inclined direction, thereby increasing the overall strength of the mechanism and ensuring the stability of the inclined ejector rod 3 when ejecting or forming products.

[0036] Preferably, the moving block 2 in this solution is further provided with a guide groove 21 connected to the engaging groove 20. Figure 2 As shown, the guide groove 21 is located above the engaging groove 20 and is designed as a waist-shaped groove as a whole. When the moving block 2 moves back and forth in the vertical direction, the auxiliary rod 4 is bound to be pressed against the two side walls of the guide groove 21 in the length direction due to the push of the engaging block 51 and the connecting block 50, thereby limiting the distance of the reciprocating movement of the moving block 2 in the vertical direction, ensuring that the inclined ejector rod 3 can eject the product within the required range and can be reset in time.

[0037] A mounting block 6 is detachably connected to the movable mold base, and a connecting hole 60 is provided in the mounting block 6. A first connecting shaft 40 and a second connecting shaft 41 are respectively provided at both ends of the auxiliary rod 4. The first connecting shaft 40 is rotatably connected in the connecting hole 60, and the second connecting shaft 41 is rotatably connected in the fixed block 1.

[0038] like Figure 2 As shown, in the present scheme, the first connecting shaft 40 and the second connecting shaft 41 at both ends of the auxiliary rod 4 are respectively hinged to the fixed block 1 and the mounting block 6, and the connecting block 50 can rotate relative to the locking block 51 by relying on the fixed shaft 52, so that when the connecting block 50 on the inclined ejector rod 3 rotates relative to the locking block 51 due to the movement of the moving block 2, the connecting block 50 on the auxiliary rod 4 and the top end of the auxiliary rod 4 (relying on the rotation of the first connecting shaft) can rotate synchronously relative to the locking block 51, ensuring that the auxiliary rod 4 and the inclined ejector rod 3 are placed in parallel, thereby playing an auxiliary guiding effect on the inclined ejector rod 3 when it moves back and forth along its own inclined direction, thereby enhancing the overall stability of the mechanism.

[0039] A clearance groove 61 is formed in both the mounting block 6 and the fixing block 1 , and the first connecting shaft 40 and the second connecting shaft 41 are both disposed in the clearance groove 61 to provide space required for the auxiliary rod 4 to move.

[0040] Further, in moving block 2 along Figure 2 When moving vertically downward, the engaging block 51 drives the connecting block 50 to move leftward along the engaging groove 20. With the rotation of the fixed shaft 52 relative to the engaging block 51 and the rotation of the first connecting shaft 40 relative to the mounting block 6, the auxiliary rod 4 can always be parallel to the inclined ejector rod 3. In this process, the clearance groove 61 on the mounting block 6 provides Figure 2 The displacement space when the top end of the middle auxiliary rod 4 rotates around the first connecting shaft 40, similarly, the clearance groove 61 in the fixed block 1 provides Figure 2 The displacement space when the bottom end of the auxiliary rod 4 rotates around the second connecting shaft 41 ensures that the auxiliary rod 4 can always maintain a parallel placement posture with the inclined ejector rod 3 under the movement of the moving block 2.

[0041] Preferably, a guide sleeve is provided in the movable mold base, and the inclined ejector rod 3 is movably inserted in the guide sleeve, which cooperates with the inclined guide hole 10 in the above-mentioned fixed block 1 to further improve the smoothness and stability of the inclined ejector rod 3 when performing the inclined ejection action.

[0042] Preferably, in the present solution, the driving mode of the moving block 2 can be replaced by other driving devices such as a hydraulic cylinder and a pneumatic cylinder.

[0043] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0044] In addition, in the present invention, the descriptions of "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0045] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
