Description

Technical Field

[0001] This utility model belongs to the field of precision mechanical casting, and in particular relates to an auxiliary device for simulating the ejection of a push rod. Background Technology

[0002] Currently, the requirements for the dimensional accuracy of castings are becoming increasingly stringent, and the development cycle for castings is short and demanding. Therefore, a large number of castings require precision casting to meet the needs of technological development. However, castings require high precision molds with dimensional tolerances within 0.02mm. Therefore, every step in the operation of precision molds must be strictly controlled, and the assembly accuracy of precision molds must also be high.

[0003] When using existing precision molds, there is a problem with the ejector pins not being installed correctly. As a result, the ejector pins cannot be ejected to the required height and then reset, causing the precision molds to malfunction and affecting the normal production of castings. If the ejector pins of the precision molds are adjusted on the production line, the limited space may cause the grinding tools to damage the precision mold body.

[0004] Therefore, there is an urgent need to design an auxiliary device to simulate the ejection of the push rod and solve the problems mentioned above. Utility Model Content

[0005] To address the technical problem mentioned in the background art that improper ejector pin installation can affect the normal use of precision molds, and that on-site maintenance can easily lead to damage to the precision mold body by grinding tools, an auxiliary device that simulates ejector pin ejection is provided to solve the problem of molds being unable to reset due to improper ejector pin ejection.

[0006] To achieve the above objectives, the specific technical solution of the auxiliary device for simulating the ejection of a push rod according to this utility model is as follows: An auxiliary device for simulating ejection of a push rod includes a support plate with a clamping assembly that slides along a slide rail on the support plate. The clamping assembly clamps a precision mold onto the support plate via a first cylinder. The support plate has an ejector column connected to a second cylinder. The second cylinder drives the ejector column to lift the top plate of the precision mold, causing the top plate to eject the push rod of the precision mold, thereby simulating the lifting and resetting action of the push rod.

[0007] Furthermore, the clamping assembly includes a first fixing plate and a second fixing plate, which are spaced apart on both sides of the support plate so that the first fixing plate and the second fixing plate clamp the precision mold on the support plate.

[0008] Furthermore, the slide includes a first slide and a second slide, and a first fixed plate and a second fixed plate are slidably disposed on the first slide and the second slide, respectively.

[0009] Furthermore, the first and second slides are spaced apart on the support plate along its length.

[0010] Furthermore, a first cylinder is provided on the side of the support plate away from the precision mold, and the first cylinder drives the first fixed plate and the second fixed plate to slide along the length direction of the support plate.

[0011] Furthermore, a limiting post is vertically connected to the support plate, and an ejector post is provided inside the limiting post so that the ejector post can slide along the length direction of the limiting post.

[0012] Furthermore, a second cylinder is provided on the side of the support plate away from the limiting post. The second cylinder is connected to one end of the ejector post so that the second cylinder drives the ejector post to extend out of the limiting post from the side away from the second cylinder.

[0013] Furthermore, the precision mold abuts against the support plate via the base plate, which has through holes, and the base plate is inserted into the limiting post through the through holes.

[0014] Furthermore, the end of the limiting post away from the support plate abuts against the top plate, and the second cylinder drives the ejector post to extend out of the limiting post, so that the top plate moves upward to eject the ejector rod.

[0015] Furthermore, the base plate is clamped onto the support plate by the first fixing plate and the second fixing plate.

[0016] The auxiliary device for simulating the ejection of a push rod of this utility model has the following advantages: By using ejector pins to lift the top plate, the precision mold with ejector pins can be ejected to a certain height during the fitting of ejector pins. This avoids the time delay caused by irreparable mold damage due to limited production space, which necessitates the re-machining of the mold. Furthermore, the precision mold is secured by the first and second fixing plates. This application simulates whether the precision mold top plate can be reset after ejection following ejection of the ejector pin fitting, eliminating the need for precision mold turnover and adjustment. If the ejector pin of the precision mold is not lifted to the correct position, it can be reinstalled, fitted, and adjusted in the mold manufacturing workshop without occupying on-site production time. This means that the precision mold can be adjusted before being placed on the production line for formal use, shortening maintenance time. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0021] The following is a reference to the appendix. Figure 1 To be continued Figure 4 This invention describes an auxiliary device for simulating the ejection of a push rod.

[0022] like Figure 1 As shown, the auxiliary device for simulating the ejection of the ejector rod in this utility model includes a support plate 1, a clamping assembly on the support plate 1, the clamping assembly sliding along the slide rail on the support plate 1, the clamping assembly clamping the precision mold 4 on the support plate 1 by a first cylinder 2, an ejector column 12 on the support plate 1, the ejector column 12 being connected to a second cylinder 3, the second cylinder 3 driving the ejector column 12 to lift the top plate 5 of the precision mold 4, so that the top plate 5 ejects the ejector rod 6 of the precision mold 4, thereby simulating the lifting and resetting action of the ejector rod 6.

[0023] The ejector column 12 lifts the top plate 5, and the precision mold 4 with the ejector rod 6 can be ejected to a certain height when the ejector rod 6 is being fitted. This avoids the time delay caused by the mold being damaged due to the narrow production space and the need to re-cut the block. The precision mold 4 is fixed by the first fixing plate 7 and the second fixing plate 8.

[0024] Furthermore, such as Figure 1 and Figure 3As shown, the clamping assembly includes a first fixing plate 7 and a second fixing plate 8, which are spaced apart on both sides of the support plate 1 so that the first fixing plate 7 and the second fixing plate 8 clamp the precision mold 4 on the support plate 1; the slide includes a first slide 9 and a second slide 10, which are slidably disposed on the first slide 9 and the second slide 10 respectively; the first slide 9 and the second slide 10 are spaced apart on the support plate 1 along the length direction of the support plate 1.

[0025] In this embodiment, the clamping assembly consists of a first fixing plate 7 and a second fixing plate 8, and the first fixing plate 7 and the second fixing plate 8 have the same shape and size. Preferably, the first fixing plate 7 and the second fixing plate 8 are placed on the upper surface of the support plate 1, and the first fixing plate 7 and the second fixing plate 8 are spaced apart. The precision mold 4 is clamped by the first fixing plate 7 and the second fixing plate 8, thereby fixing the precision mold 4 on the support plate 1.

[0026] A first slide rail 9 and a second slide rail 10 are spaced apart along the length of the support plate 1. The first fixing plate 7 and the second fixing plate 8 slide along the first slide rail 9 and the second slide rail 10 respectively, thereby clamping the precision molds 4 of different sizes on the support plate 1.

[0027] Furthermore, such as Figure 1 and Figure 2 As shown, a first cylinder 2 is provided on the side of the support plate 1 away from the precision mold 4. The first cylinder 2 drives the first fixed plate 7 and the second fixed plate 8 to slide along the length direction of the support plate 1. A limit post 11 is vertically connected on the support plate 1. An ejector post 12 is provided inside the limit post 11 so that the ejector post 12 slides along the length direction of the limit post 11. A second cylinder 3 is provided on the side of the support plate 1 away from the limit post 11. The second cylinder 3 is connected to one end of the ejector post 12 so that the second cylinder 3 drives the ejector post 12 to extend out of the limit post 11 from the end away from the second cylinder 3.

[0028] In this embodiment, preferably, the lower surface of the support plate 1 is connected to the first cylinder 2, and the hydraulic rods on both sides of the first cylinder 2 are connected to the first fixed plate 7 and the second fixed plate 8, so that the first fixed plate 7 and the second fixed plate 8 slide simultaneously along the first slide rail 9 and the second slide rail 10.

[0029] The upper surface of the support plate 1 is connected to a limiting post 11. Preferably, the limiting post 11 is located between the first slide rail 9 and the second slide rail 10. The lower surface of the support plate 1 is also connected to a second cylinder 3. The hydraulic rod of the second cylinder 3 is connected to the ejector post 12 that is slidably disposed in the limiting post 11, thereby driving the ejector post 12 to extend out of the limiting post 11 or retract into the limiting post 11.

[0030] Furthermore, such as Figure 1 and Figure 4As shown, the precision mold 4 abuts against the support plate 1 via the base plate 13. The base plate 13 has a through hole, and the base plate 13 is inserted into the limiting post 11 through the through hole. The end of the limiting post 11 away from the support plate 1 abuts against the top plate 5. The second cylinder 3 drives the ejector post 12 to extend out of the limiting post 11, so that the top plate 5 moves upward to eject the ejector rod 6. The base plate 13 is clamped on the support plate 1 by the first fixing plate 7 and the second fixing plate 8.

[0031] In this embodiment, the precision mold 4 is composed of a base plate 13, a top plate 5 and a push rod 6. The precision mold 4 abuts against the support plate 1 through the base plate 13. Preferably, the base plate 13 is provided with a through hole that matches the shape of the limiting post 11, so that when the base plate 13 abuts against the support plate 1, the limiting post 11 can be inserted into the base plate 13.

[0032] Furthermore, the limiting post 11 is inserted into the bottom plate 13 and abuts against the top plate 5. The second cylinder 3 drives the ejector post 12 to extend out of the limiting post 11, thereby causing the top plate 5 to be lifted by the ejector post 12, realizing the ejection of the ejector rod 6. The construction personnel determine whether the function of the ejector rod 6 meets the standard by judging the extension position of the ejector rod 6. If the ejector rod 6 is not in the correct position, the construction personnel can calibrate the ejector rod 6 before the precision mold 4 is officially used in the production line for production.

[0033] Preferably, the precision mold 4 abuts against the support plate 1 via the base plate 13, and the first fixing plate 7 and the second fixing plate 8 fix the precision mold 4 by clamping the base plate 13.

[0034] The working principle of the auxiliary device for simulating the ejection of the push rod in this utility model is as follows: First, the base plate 13 of the precision mold 4 is placed against the support plate 1, that is, the limiting post 11 of the support plate 1 is inserted into the through hole of the base plate 13 to initially limit the precision mold 4. Then, the first fixing plate 7 and the second fixing plate 8 are driven by the first cylinder 2 to clamp the bottom plate 13; Then, the second cylinder 3 drives the ejector column 12 to extend out of the limiting column 11 and abut against the top plate 5; Then, continue to drive the ejector column 12 to lift the top plate 5, thereby causing the top plate 5 to eject the ejector rod 6, and determine the ejection position of the ejector rod 6; Finally, the push-out column 12 is driven to retract into the limit column 11, and the reset position of the push rod 6 is determined.

[0035] Based on the auxiliary device for simulating ejector pin ejection, this utility model can determine whether the top plate 5 of the precision mold 4 can be reset after being ejected by the simulated ejector pin 6. This eliminates the need for turnover and adjustment of the precision mold 4. If the ejector pin 6 of the precision mold 4 cannot be lifted into place, the precision mold 4 can be placed on the production line for debugging before it is officially used, further shortening the maintenance time.

[0036] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
