Description

Technical Field

[0001] The present invention relates to mold apparatus, such as a mold apparatus having a mold for forming a sand mold. Background Technology

[0002] For example, Japanese Patent No. 2610197 discloses technology related to mold-making apparatuses. Molds used in mold-making apparatuses are heavy, therefore, as described in Japanese Patent No. 2610197... Figure 1 As described in the text, a movable pressure plate supporting the moving mold is maintained by a structure such as a tie rod. Summary of the Invention

[0003] However, when using tie rods to hold the moving mold in place, the frame used to support the tie rods becomes larger, resulting in increased constraints related to the setup.

[0004] This invention was made to solve such problems and aims to reduce the constraints related to the setup of the mold assembly.

[0005] One embodiment of the mold apparatus according to the present invention includes: a fixed mold base supporting a fixed mold; a movable mold base supporting a movable mold; a frame having the fixed mold base fixed thereon and extending in the moving direction of the movable mold base, and being formed as a wall; and a retaining device supporting the movable mold base in a movable manner on the frame, wherein the frame, when the apparatus is installed, is provided along at least one side of the movable mold base other than its upper surface, and the retaining device supports the movable mold base on one side of the movable mold base.

[0006] In the mold apparatus of the present invention, the movable mold base is made into a cantilever support.

[0007] Through this invention, and the mold apparatus according to this invention, it is possible to reduce the constraints related to the setup of the mold apparatus.

[0008] The above and other objects, features and advantages of this disclosure will be more fully understood from the detailed description and accompanying drawings given below, which are given by way of example only and should not be considered as limiting the disclosure.

[0013] Figure 5 This is a schematic diagram of the mold apparatus involved in Embodiment 4. Detailed Implementation

[0014] Implementation Method 1

[0015] First of all, at Figure 1 A schematic diagram of the mold apparatus 1 according to Embodiment 1 is shown. Figure 1 In the middle, the side view obtained by observing the device from the side when it is in the state of having the mold device 1 installed is shown at the top, and the top view obtained by observing the device from the top is shown at the bottom.

[0016] like Figure 1 As shown, the mold assembly 1 according to Embodiment 1 includes a frame 10, a fixed mold base 11, a movable mold base 12, holding devices (e.g., a track 13 and a guide 14), and driving devices (a cylinder 15 and a plunger 16). Additionally, a fixed mold 20 and a movable mold 21 are provided in the mold assembly 1. The fixed mold 20 is supported on the fixed mold base 11. The movable mold 21 is supported on the movable mold base 12. Furthermore, the fixed mold 20 and the movable mold 21 can be replaced depending on the molded article to be manufactured.

[0017] Regarding the frame 10, it is fixedly connected, and the fixed mold base 11 is mounted in a movable manner. Furthermore, the frame 10 is formed as a wall shape extending in the moving direction of the fixed mold base 11. The fixed mold base 11 supports the fixed mold 20. The movable mold base 12 supports the movable mold 21 along at least one side.

[0018] exist Figure 1 In the example shown, the support device supports the fixed mold base 11 in a movable manner to the frame 10. Figure 1 In the example shown, a combination of track 13 and guide 14 is used as a support device. Track 13 is fixed to the fixed mold base 11. Guide 14 is inserted into the track in a manner that allows it to move on the track and is fixed to the movable mold base 12.

[0019] In addition, Figure 1 In the example shown, the driving mechanism employs a combination of cylinder 15 and plunger 16. Plunger 16 is connected to the central portion of the movable mold base 12. Cylinder 15 moves the movable mold base 12 by sliding plunger 16 in the pushing and pushing directions. Figure 1 It moves laterally (e.g., in the Y direction).

[0020] Here, in the mold device 1 according to Embodiment 1, the frame 10, when the device is installed, is provided along at least one side of the movable mold base 12 except for the upper surface, and the retaining device supports the movable mold base 12 on one side. Figure 1 In the example shown, frame 10 is positioned along one side of the movable mold base 12. That is, in Figure 2 In the mold apparatus 1 according to Embodiment 1 shown, the movable mold base 12 is cantilevered. Furthermore, the mold apparatus 1 according to Embodiment 1 is specifically configured such that other structures do not cover the area where the fixed mold 20 and the movable mold 21 contact.

[0021] In the mold apparatus 1 according to Embodiment 1, molding sand is fed into the mold frame formed by the fixed mold 20 and the movable mold 21 from the upper side (e.g., the Z direction). Therefore, the portion of the upper surface of the mold apparatus 1 where the fixed mold 20 and the movable mold 21 are combined needs to be exposed.

[0022] In addition, Figure 1 In the example shown, the frame 10, fixed mold base 11, movable mold base 12, guide 14, cylinder 15, and plunger 16 are shown exposed, but they may also have covers. In this case, an opening is provided on the cover centered on the area where the fixed mold 20 contacts the movable mold 21.

[0023] like Figure 1 As shown, in the mold device 1 according to Embodiment 1, by using the guide 14 and the track 13 as support devices for the moving mold base 12, the structure for supporting the support device itself, such as the tie rod, is no longer needed, thus reducing the overall volume of the device.

[0024] Accordingly, in the mold apparatus 1 according to Embodiment 1, even though the two opposite sides of the movable mold base 12 are supported by the track 13 and the guide 14 respectively, the overall volume of the apparatus can be reduced because there is no need for a structure that supports the support device itself, such as a tie rod. However, compared with Figure 1 Compared to the mold device 1 with the cantilever support structure shown, the overall volume reduction effect is smaller.

[0025] In addition, Figure 1 In the example shown, track 13 and guide 14 are shown as support devices, but the track can also be replaced with a ball screw, and an actuator can be added to rotate the ball screw. When using a ball screw, a threaded hole that meshes with the ball screw needs to be provided in the moving mold base 12. In this way, even when using a combination of ball screw and actuator, the overall volume of the mold device 1 can be reduced because the structure supporting the ball screw can be extremely simple.

[0026] Furthermore, in the mold device 1 according to Embodiment 1, the support device is only fixed to the frame 10, and there are no restrictions on other parts, so the degree of freedom in setting up control equipment and the like attached to the mold device 1 can be improved.

[0027] Implementation Method 2

[0028] In Embodiment 2, another embodiment of the mold apparatus 1 according to Embodiment 1 will be described. Furthermore, in the description of Embodiment 2, for components that are identical to those described in Embodiment 1, the same reference numerals are used as in Embodiment 1, and their descriptions are omitted.

[0029] At Figure 2 A schematic diagram of the mold device 2 according to Embodiment 2 is shown. Figure 2 As shown, the mold apparatus 2 according to Embodiment 2 has a fixed mold 30 and a movable mold 31 instead of a fixed mold 20 and a movable mold 21. The fixed mold 30 is formed by adding a fixed mold positioning key 30a to the fixed mold 20. Similarly, the movable mold 31 is formed by adding a movable mold positioning key 31a to the movable mold 21. The fixed mold positioning key 30a and the movable mold positioning key 31a are, as shown... Figure 2 As shown in region A of the figure below, the fixed mold 30 and the movable mold 31 are combined and fitted with a concave-convex shape. From another viewpoint, the positioning key is that one of a pair of positioning recesses and protrusions is formed in the fixed mold 20, and the other of a pair of positioning recesses and protrusions is formed in the movable mold 21.

[0030] The positioning key is positioned on at least one side that includes an edge opposite to the edge where a retaining device (e.g., guide 14) is located. Figure 2 In the example shown, a movable mold positioning key 31a is provided on the side of the movable mold base 12 opposite to the side where the guide 14 is provided. Additionally, a fixed mold positioning key 30a is provided on the side of the fixed mold 30 corresponding to the side where the movable mold positioning key 31a is provided.

[0031] In this way, by providing a positioning key, positioning the fixed mold 30 and the movable mold 31 when they are mounted on the fixed mold base 11 and the movable mold base 12 becomes easier. Furthermore, the positioning key formed on the side of the fixed mold 30 where the guide 14 is located facilitates positioning. Figure 2 Compared to the example shown, this method can further improve positioning accuracy.

[0032] Furthermore, the locating key is preferably located near the center of the edge. By placing the locating key near the center of the edge, displacement of the key position caused by thermal expansion of the mold can be suppressed.

[0033] Implementation Method 3

[0034] In Embodiment 3, another embodiment of the mold apparatus 1 according to Embodiment 1 will be described. Furthermore, in the description of Embodiment 3, for components that are identical to those described in Embodiment 1, the same reference numerals as in Embodiment 1 will be used, and their descriptions will be omitted.

[0035] At Figure 3 A schematic diagram of the mold apparatus 3 according to Embodiment 3 is shown. Figure 3 As shown, the mold device 3 according to Embodiment 3 is provided with a scale guide 40 on the frame 10. Figure 3 An enlarged view of the scale guide 40 is shown. Figure 3 As shown, the scale guide 40 has at least one machined surface 41 with a predetermined perpendicularity and flatness. Furthermore, the guide fixture 42 can be mounted on the machined surface 41. The guide fixture 42 can be installed during inspection as described later, or it can be installed periodically.

[0036] Here, the inspection using the scale guide 40 will be explained. Figure 4 A diagram illustrating the steps for inspecting the mold apparatus 3 according to Embodiment 3 is shown. Figure 4 As shown, during inspection, the scale 50 is placed against the frame 10 along the machined surface 41. Additionally, dimensional reference lines RL1 and RL2 are provided on the moving mold base 12, formed at positions based on the machined surface 41. The base-side reference line RL1 is, for example, a line that intersects the machined surface 41 perpendicularly. The base-side reference line RL2 is, for example, a line parallel to the machined surface 41 at a certain distance from it. Furthermore, a scale-side reference line SL is provided on the scale 50 at a position consistent with the base-side reference line RL2. Then, the scale 50 is placed against the machined surface 41, with the base-side reference line RL1 becoming parallel to the edge of the scale 50. By checking whether the base-side reference line RL1 and the scale-side reference line SL overlap, it is confirmed whether the moving mold base 12 is tilted from the reference position. Furthermore, regarding the machined surface 41, although... Figure 4 Not shown, but by using the machined surface 41, the scale 50 can be easily attached to the specified tilt and position.

[0037] In this way, by using the scale guide 40, the tilt of the movable mold base 12 can be easily confirmed in the mold device 3 according to Embodiment 3. In the cantilever mold device 3, the movable mold base 12 is prone to tilting due to deterioration over time. By easily checking this tilt, the maintenance process of the mold device 3 can be simplified.

[0038] Implementation Method 4

[0039] In Embodiment 4, another embodiment of the mold apparatus 1 according to Embodiment 1 will be described. Furthermore, in the description of Embodiment 4, for components that are identical to those described in Embodiment 1, the same reference numerals as in Embodiment 1 will be used, and their descriptions will be omitted.

[0040] At Figure 5 A schematic diagram of the mold assembly according to Embodiment 4 is shown. Figure 5 As shown, in embodiment four, the frame 10 is disposed on the lower side of the fixed mold base 11 and the movable mold base 12. Similarly, the frame 10 can also be disposed on the lower side of the fixed mold base 11 and the movable mold base 12, rather than on the side. By arranging it in this way, the depth direction of the device can be reduced ( Figure 5 The width (in the X direction). In this way, by reducing the size in the depth direction, the footprint of the device can be reduced.

[0041] It will be apparent from the above description of this disclosure that embodiments of this disclosure may be varied in many ways. These variations should not be considered as departing from the spirit and scope of this disclosure, and it will be apparent to those skilled in the art that all such modifications are intended to be included within the scope of the claims.
