Description

TECHNICAL FIELD

[0001] The present application relates to the field of jig equipment, in particular to a mold ejection mold split jig. BACKGROUND

[0002] Some workpieces such as rings need to be molded by molds, and the molds are divided into upper molds and lower molds. The upper mold and the lower mold make the internal workpiece solidify and form after pouring. After molding, the upper mold and the lower mold need to be separated, and then the workpiece can be taken out from the mold.

[0003] However, due to the pouring forming, the pouring material adheres to the inner wall of the upper mold and the lower mold, and the adhesion is strong. When manually separating, the upper mold or the lower mold needs to be shaken to loosen the pouring material. However, this method is easy to damage the internal workpiece and affect the quality of the workpiece. SUMMARY

[0004] In order to improve the above problems, the present application provides a mold ejection mold split jig.

[0005] The mold ejection mold split jig provided by the present application adopts the following technical scheme:

[0006] A mold ejection mold split jig is used for separating the upper mold and the lower mold of the mold. The mold ejection mold split jig comprises a mounting seat, a supporting seat, a driving member and a limiting member. The supporting seat provides a place for the mold. The supporting seat is mounted on the top surface of the mounting seat, and there is a mounting space between the mounting seat and the supporting seat. A ejection hole is formed in the end of the supporting seat away from the mounting seat. The driving member is mounted on the top surface of the mounting seat and located in the mounting space. The driving member is provided with a driving end which extends outwardly from the supporting seat through the ejection hole. The limiting member is mounted on the top of the supporting seat. When the mold is placed in the supporting seat, the lower mold is inserted into the limiting member. The driving member drives the driving end to rise and penetrate the lower mold, and then the upper mold is ejected to separate the upper mold and the lower mold.

[0007] By adopting the above technical scheme, when the mold is placed in the supporting seat, the lower mold is inserted into the limiting member. Then the driving member drives the driving end to rise. The driving end penetrates the ejection hole and the demolding hole, and continues to move upward until it contacts the upper mold. With the continuous rising, the upper mold is ejected to separate the upper mold and the lower mold, thereby achieving the effect of convenient mold split. The mold split operation is convenient and fast, and the mold split efficiency can be improved.

[0008] Optionally, the driving end is further provided with an ejection plate. A plurality of ejection rods are arranged on the ejection plate. The number of ejection holes is equal to the number of ejection rods, and the ejection rods correspond to the ejection holes one by one.

[0009] By adopting the technical scheme, when the driving member drives the driving end to lift, the ejection plate is lifted, the ejection rods are located on the ejection plate, and the ejection rods are lifted to extend out of the ejection holes and penetrate through the demolding holes to eject the upper mold. The ejection plate is arranged to lift the plurality of ejection rods uniformly, and the ejection rods are used to eject the upper mold synchronously. In this way, the upper mold is subjected to force from multiple ejection points, the ejection is more stable, and the damage of the workpiece caused by the uneven force and the tilting of the upper mold during demolding is avoided.

[0010] Optionally, the mounting seat is provided with a plurality of guide portions; one end of the guide portion is connected with the mounting seat, and the other end is connected with the bottom of the support seat; a guide hole is formed in the ejection plate and is in sliding connection with the guide portion through the guide hole.

[0011] By adopting the technical scheme, the ejection plate can only move up and down along the guide portion, and the guide portion is used for limiting and fixing the moving path of the ejection plate, so that the ejection rod cannot deviate and cannot penetrate the ejection hole.

[0012] Optionally, a stepped port is formed in the top of the support seat, and the ejection hole is located in the stepped port.

[0013] By adopting the technical scheme, the stepped port can make the mold fit the wall of the stepped port, so that the position of the mold is more easily determined, the time for connecting the demolding hole and the ejection port is reduced, and the efficiency of mold splitting is improved.

[0014] Optionally, the limiting member is a limiting rod, and the limiting rod is installed on the vertical wall surface of the stepped port in the horizontal direction.

[0015] By adopting the technical scheme, the lower mold cannot move in the vertical direction due to the limiting of the limiting rod, and can only move in the direction in which the limiting rod is formed, so that the position of the lower mold can be stable when the ejection rod penetrates the ejection hole and the demolding hole.

[0016] Optionally, the number of the limiting rods is several.

[0017] By adopting the technical scheme, the stability of the position of the lower mold is improved by using a plurality of limiting rods, so that the lower mold does not deviate to one side when the force is unbalanced.

[0018] Optionally, the stepped port is in the shape of an L-shaped port, and the mold moves along the L-shaped surface of the stepped port to be inserted with the limiting member.

[0019] By adopting the technical scheme, the stepped port in the shape of an L-shaped port can quickly position the mold, and the mold only needs to move along the wall surface of the L-shaped port to be quickly inserted with the limiting rod.

[0020] Optionally, an inner concave surface that matches the mold pattern is further formed in the step opening.

[0021] By adopting the above technical scheme, the mold can be smoothly placed in the inner wall of the step opening through the inner concave surface, the stability is improved, and the deviation after stress is reduced.

[0022] In summary, the present application has at least one of the following beneficial technical effects:

[0023] 1. When the mold is placed in the support seat, the lower mold is inserted with the limiting piece, then the driving part drives the driving end to rise, the driving end penetrates the ejection hole and the demolding hole, and continues to move upward until it contacts the upper mold. With the continuous rising, the upper mold is ejected, and the upper mold and the lower mold are separated, thereby achieving the effect of convenient mold separation. The mold separation operation is convenient and fast, and the mold separation efficiency can be improved.

[0024] 2. When the driving part drives the driving end to rise and fall, the ejection plate is driven to rise and fall, and the ejection rod is located on the ejection plate, thereby driving the plurality of ejection rods to rise and fall. The ejection rod extends out of the ejection hole and penetrates the demolding hole to eject the upper mold. By setting the ejection plate to uniformly drive the plurality of ejection rods to rise and fall, and using the ejection rod to synchronously eject the upper mold, this way can make the upper mold receive force from multiple ejection points, making the ejection more stable, and avoiding uneven force causing the upper mold to be skewed and causing damage to the workpiece during demolding.

[0025] 3. The ejection plate can only move up and down along the guide part, and the guide part is limited and fixed to allow the ejection plate to move along a fixed path, avoiding the ejection rod from deviating and being unable to penetrate the ejection hole.

[0026] 4. The step opening can make the mold fit the wall of the step opening, thereby making the position of the mold easier to determine, reducing the time of aligning the demolding hole with the ejection port, and improving the mold separation efficiency. BRIEF DESCRIPTION OF DRAWINGS

Figure 1 -Appendix Figure 3 The present application is further described in detail.

[0037] The embodiments of the present application disclose a mold ejection parting jig.

[0038] A mold ejection split mold jig is used for the ejection and separation of an upper mold 11 and a lower mold 12 of a mold 1, and the pattern of the mold 1 can refer to Figure 1 as shown.

[0039] Referring to Figure 1 as shown, the jig comprises a mounting seat 2, a support seat 3, a driving member 4 and a limiting member 5; the mounting seat 2 adopts a rectangular plate structure and is the bottommost mounting platform; the support seat 3 provides a place for the mold 1, and the support seat 3 is installed on the top surface of the mounting seat 2, and there is a mounting space between the mounting seat 2 and the support seat 3; the support seat 3 is in the shape of a Chinese character, and the top surface of the support seat 3 is a placing platform for the mold 1.

[0040] An ejection hole 31 is formed at the end of the support seat 3 away from the mounting seat 2, and the driving member 4 is installed on the top surface of the mounting seat 2 and located in the mounting space; the driving member 4 can adopt any driving element such as an electric push rod, a pneumatic cylinder or an oil cylinder, which can be selected according to requirements; the ejection hole 31 can refer to Figure 2 or Figure 3 .

[0041] The driving member 4 is provided with a driving end which extends out of the support seat 3 through the ejection hole 31; the driving end can be the extension end of any driving element such as an electric push rod, a pneumatic cylinder or an oil cylinder; the driving member 4 can drive the driving end to move towards the ejection hole 31 and contact the mold 1.

[0042] The limiting member 5 is installed on the top of the support seat 3; when the mold 1 is placed on the support seat 3, the lower mold 12 is inserted into the limiting member 5; the lower mold 12 of the mold 1 is provided with an insertion hole matched with the limiting member 5, so that when the mold 1 is placed on the top surface of the support seat 3, the lower mold 12 can move along the limiting member 5 through the insertion hole and be inserted into the limiting member 5; the limiting member 5 can be used to limit and fix the lower mold 12, so that when it is necessary to separate the upper mold 11 from the lower mold 12, the lower mold 12 cannot be ejected and moved.

[0043] The lower mold 12 is provided with an ejection hole through which the driving end penetrates; when the mold 1 is inserted into the limiting member 5, the ejection hole is communicated with the ejection hole 31, so that the driving end can continue to move upwards along the ejection hole until it contacts the upper mold 11, thereby ejecting the upper mold 11.

[0044] Specifically, when the mold 1 is placed on the support seat 3, the lower mold 12 is inserted into the limiting member 5; then the driving member 4 drives the driving end to rise; the driving end penetrates the ejection hole 31 and the ejection hole and continues to move upwards until it contacts the upper mold 11; with the continuous rising, the upper mold 11 is ejected, the upper mold 11 is separated from the lower mold 12, thereby achieving the effect of convenient mold splitting; the mold splitting operation is convenient and fast, and the mold splitting efficiency can be improved.

[0045] In some embodiments, reference can be made to Figure 2As shown, the driving end is also provided with an ejection plate 41, and the ejection plate 41 is provided with a plurality of ejection rods 42. The ejection plate 41 can be a rectangular plate, and the size and pattern of the rectangular plate are smaller than the mounting space, so that the ejection plate 41 can be lifted along the mounting space. The ejection rod 42 is located on the top surface of the ejection plate 41, and the ejection rod 42 is lifted synchronously when the ejection plate 41 is lifted.

[0046] The number of ejection holes 31 is set to be several, and the ejection rod 42 corresponds to the ejection hole 31 one by one, so that the ejection rod 42 can be ejected out of the support seat 3 from the ejection hole 31 when the ejection plate 41 is lifted.

[0047] Specifically, when the driving part 4 drives the driving end to lift, the ejection plate 41 is lifted, and the ejection rod 42 is located on the ejection plate 41, so as to drive a plurality of ejection rods 42 to lift. The ejection rod 42 extends out of the ejection hole 31 and penetrates the demolding hole to eject the upper die 11. By setting the ejection plate 41 to uniformly lift a plurality of ejection rods 42, and using the ejection rod 42 to synchronously eject the upper die 11, this way can make the upper die 11 receive force from multiple ejection points, so that the ejection is more stable, and the uneven force does not cause the upper die 11 to be skewed to damage the workpiece during demolding.

[0048] In some embodiments, referring to Figure 2 As shown, the mounting seat 2 is provided with a plurality of guide parts 21; one end of the guide part 21 is connected with the mounting seat 2, and the other end is connected with the bottom of the support seat 3. The guide part 21 can be a guide rod, and the two ends of the guide rod are respectively fixedly connected with the top surface of the mounting seat 2 and the bottom surface of the support seat 3, which can increase the stability of the support seat 3. When the driving part 4 provides driving force for the driving end or the ejection rod 42 to eject the upper die 11 upward, the upper die 11 will have a reaction force applied to the support seat 3. The connection between the support seat 3 and the mounting seat 2 is more stable through the guide part 21, so that the support seat 3 cannot be separated from the mounting seat 2 even if it is stressed.

[0049] The ejection plate 41 is provided with a guide hole, and the guide hole is slidably connected with the guide part 21. The guide part 21 is located in the guide hole, and the number of guide parts 21 is consistent with the number of guide holes and corresponds to each other, so as to fix the position of the ejection plate 41. The ejection plate 41 can only move up and down along the guide part 21. The guide part 21 is used for limiting and fixing the moving path of the ejection plate 41, so as to avoid the ejection rod 42 from deviating and being unable to pass through the ejection hole 31.

[0050] In some embodiments, referring to Figure 3 As shown, the top of the support seat 3 is provided with a stepped opening 32, and the ejection hole 31 is located in the stepped opening 32. The stepped opening 32 can make the mold 1 fit the wall of the stepped opening 32, so that the position of the mold 1 is easier to determine, the time for connecting the demolding hole and the ejection hole is reduced, and the efficiency of mold splitting is improved.

[0051] Further, the limiting piece 5 adopts a limiting rod, which is installed in the vertical wall surface of the stepped port 32 along the horizontal direction. The insertion hole of the lower mold 12 is consistent with the limiting rod, so that the lower mold 12 can be inserted with the limiting rod through the insertion hole. The limiting rod is arranged along the horizontal direction, so that the mold 1 moves horizontally along the stepped port 32 to the limiting rod and is inserted with the limiting rod. In this way, the lower mold 12 cannot move along the vertical direction due to the limiting of the limiting rod, but can only move along the direction in which the limiting rod is opened. Therefore, when the ejection rod 42 penetrates the ejection hole 31 and the demolding hole, the position of the lower mold 12 can be stable, and the lower mold 12 cannot be simultaneously ejected along the vertical direction when the upper mold 11 is ejected, thereby improving the stability of the lower mold 12.

[0052] The number of limiting rods is set to be several, and the stability of the position of the lower mold 12 is improved by using the plurality of limiting rods to avoid the situation that the lower mold 12 deviates to one side when the force is unbalanced. The plurality of limiting rods realize multi-point fixing and improve the stability of the lower mold 12.

[0053] Further, as shown in Figure 3 The stepped port 32 is in the shape of an L-shaped port, and the mold 1 moves along the L-shaped surface of the stepped port 32 to be inserted with the limiting piece 5. The stepped port 32 in the shape of an L-shaped port can quickly realize positioning of the mold 1. The mold 1 only needs to move along the wall surface of the L-shaped port to be quickly inserted with the limiting piece 5 or the limiting rod, without the need to align the insertion hole of the lower mold 12 with the limiting rod and then move the mold 1. That is, when the mold 1 is attached to the wall surface of the L-shaped port, the insertion hole of the lower mold 12 is already aligned with the limiting rod, thereby achieving the effect of quick positioning and further improving the efficiency of mold splitting.

[0054] Further, an inner concave surface consistent with the mold 1 is further arranged in the stepped port 32. The inner concave surface can fit the placement position of the mold 1, so that the mold 1 can be stably placed on the inner wall of the stepped port 32, thereby improving the stability and reducing the deviation under stress.

[0055] In some embodiments, as shown in Figure 3 The support seat 3 is further provided with a through port, and the through port is communicated with the stepped port 32. The through port is slidably connected with a anti-extraction piece 6. When the anti-extraction piece 6 extends out of the through port, it blocks the moving path of the lower mold 12 from the limiting piece 5, so that the lower mold 12 cannot be separated from the limiting piece 5. When the anti-extraction piece 6 extends into the through port, it opens the moving path of the lower mold 12 from the limiting piece 5, so that the lower mold 12 can be separated from the limiting piece 5.

[0056] The anti-extraction piece 6 can adopt an anti-extraction rod, which intercepts the lower mold 12, so that the lower mold 12 cannot be separated from the limiting piece 5 when the lower mold 12 is separated from the upper mold 11, thereby ensuring the accuracy and stability of the placement position of the mold 1.

[0057] The length of the anti-disengaging piece 6 is longer than the length of the through hole, so that the anti-disengaging piece 6 can be extended or retracted from the through hole at will.

[0058] The anti-disengaging piece 6 is further provided with a handle away from one end of the stepped hole 32, so that the anti-disengaging piece 6 is more convenient to move.

[0059] The embodiments of the present application are the preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same reference numerals are used to represent the same parts in the embodiments. Therefore, any equivalent changes made according to the structure, shape and principle of the present application should be covered by the protection scope of the present application.
