Description

Technical Field

[0001] The utility model relates to the technical field related to mechanical parts, in particular to a mechanical parts mold forming device with rapid demoulding. Background Art

[0002] With the continuous development of industrialization in modern society, the significant manifestation of the work of industrial development is the continuous rise of automated equipment. In the process of manufacturing, automated equipment generally requires the use of a large number of mechanical parts. In the existing market, the processing of mechanical parts is generally performed by injection molding. Specifically, a core with a certain shape is arranged inside the lower mold cavity. Then, the upper mold and the lower mold are moved up and down to seal. After the sealing is completed, the injection molding solution is added to the lower mold. After the solution inside is cooled, a mechanical part with a core shape is formed inside the lower mold. After that, the molded mechanical part and the lower mold can be separated from each other.

[0003] However, when the injection molds currently on the market are demoulding, only an ejection mechanism is provided at the bottom of the entire lower mold, and the molded mechanical parts are ejected from the inside of the lower mold by controlling the telescopic mechanism such as a telescopic cylinder, such as an injection mold ejection mechanism and an injection mold disclosed in application No. 202211181817.4, in which a pushing mechanism is provided, which is overall arranged at the bottom of the lower mold, and the upward pushing and demoulding of the mold is completed by the upward movement of the pushing mechanism;

[0004] However, this ejection work is only applicable to mechanical parts that are narrow at the top and wide at the bottom. When the mechanical parts have severe edges or the top is wide, the traditional ejection work directly at the top will not be well applied to them. Therefore, it is necessary to set up a middle-layer mold and disassemble the middle-layer mold to complete the demoulding work. The above-mentioned demoulding work is very time-consuming. Utility Model Content

[0005] The utility model aims to provide a mechanical parts mold forming device with rapid demoulding, so as to solve the problem raised by the above background technology that the mechanical parts injection molds currently on the market can only use molds with a narrow upper and wide lower shape when performing ejection and demoulding work.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rapid demoulding mechanical parts mold forming device, including a support base, which is composed of 4 support seats and a horizontal workbench, used for supporting the entire forming device;

[0007] Connecting vertical rods, of which there are four, are arranged in a rectangular parallelepiped structure and are distributed in a rectangular shape at the top of the horizontal workbench supporting the base;

[0008] A top plate, which is located at the top of the four connecting vertical rods and has a driving mechanism disposed in the middle;

[0009] Also includes:

[0010] The driving mechanism is one of a telescopic cylinder or an automatic telescopic rod, and the top end of the driving mechanism passes through the top plate and is connected to the upper mold mechanism;

[0011] Two limit rods are symmetrically distributed above the top of the upper mold mechanism, which are used to limit the position of the upper mold mechanism;

[0012] The lower mold mechanism is a rectangular frame structure, and is located in the middle of the top horizontal workbench of the support base, and the upper position of the lower mold mechanism corresponds to the position of the upper mold mechanism;

[0013] The core mechanism is located in the middle of the lower mold mechanism and is used to mold the mechanical parts according to the different shapes of the core mechanism;

[0014] The ejection mechanism is composed of an ejection part and a contraction part. The ejection part is used to eject the formed parts, and the contraction part is used to contract the shape of the core mechanism to reduce the contact area between the core mechanism and the parts, so as to facilitate the ejection part to perform rapid ejection.

[0015] Preferably, the upper die mechanism is composed of an upper die baffle and a feed port;

[0016] The position of the upper die baffle corresponds to the position of the lower die mechanism, and is used to seal the top end of the lower die mechanism;

[0017] Preferably, the feed port is arranged at an outer side of the top end of the upper mold baffle, and is used to connect with an external feeding pipe for filling the solution into the lower mold mechanism.

[0018] Preferably, the core mechanism is arranged in an overall rectangular structure, which consists of side blocks and protruding blocks. The bottom of the side blocks is connected to the horizontal workbench on the support base, and the protruding blocks are in contact with the horizontal workbench on the support base. There are 4 side blocks and 4 protruding blocks respectively. The side blocks are in the horizontal position of the rectangle, and the protruding blocks are in the right-angle position of the rectangle.

[0019] Preferably, the top end of the protruding block is connected to an ejection mechanism, and the ejection mechanism is arranged at a middle position of the lower mold mechanism.

[0020] Preferably, a sliding protrusion is disposed on the outside of both sides of the protruding block, and a horizontal sliding groove is also disposed on the outside of both sides of the side block for the sliding protrusion outside the protruding block to slide inside the side block.

[0021] Preferably, the ejection mechanism comprises:

[0022] A control cylinder is located below the horizontal table supporting the base;

[0023] A push rod, which is a cylindrical structure, and its bottom is connected to the top of the control cylinder, and the vertical center axis position of the push rod is collinear with the center axis of the lower mold mechanism;

[0024] The ejector part includes a connecting rod and an ejector block, one end of the connecting rod is arranged at the bottom of the ejector rod, and the other end is connected to the bottom of the ejector block, and the ejector block is arranged in an annular structure, located in the middle position of the horizontal workbench of the support base and flush with it;

[0026] Compared with the prior art, the beneficial effect of the utility model is that the rapid demoulding mechanical parts mold forming device is provided with an ejection mechanism as a whole, and the ejection mechanism is composed of an ejection part and a contraction part. When the top of the mechanical parts is large or there are many edges and corners, the contraction part can be used to first reduce the outer dimensions of the mold core, and then cooperate with the ejection part to perform the ejection work. Therefore, when the top is large, the problem of directly ejecting upward at the lower end causing damage to the parts will not occur. Moreover, the whole process is achieved only through a control cylinder, and the demoulding work can be performed without the staff performing more cumbersome steps. The operation is very convenient and the processing efficiency is higher. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] See also Figure 1-7 , the utility model provides a technical solution: a rapid demoulding mechanical parts mold forming device, including a support base 1, which is composed of 4 support seats and a horizontal workbench, and is used for supporting the entire forming device;

[0037] The connecting vertical rods 2 are provided in four numbers and are arranged in a rectangular parallelepiped structure, and are distributed in a rectangular shape on the top of the horizontal workbench of the supporting base 1;

[0038] A top plate 4, which is located at the top of the four connecting vertical rods 2, and a driving mechanism 3 is arranged in the middle;

[0039] Also includes:

[0040] The driving mechanism 3 is one of a telescopic cylinder or an automatic telescopic rod, and the top end of the driving mechanism 3 passes through the top plate 4 and is connected to the upper mold mechanism 5;

[0041] Two limit rods are symmetrically distributed above the top of the upper mold mechanism 5, which are used to limit the position of the upper mold mechanism 5;

[0042] The lower mold mechanism 6 is a rectangular frame structure, and is located in the middle of the top horizontal workbench of the support base 1. The upper position of the lower mold mechanism 6 corresponds to the position of the upper mold mechanism 5.

[0043] The core mechanism 7 is located in the middle of the lower mold mechanism 6 and is used to mold the mechanical parts according to the different shapes of the core mechanism 7;

[0044] The ejection mechanism 8 is composed of an ejection part and a contraction part. The ejection part is used to eject the formed parts, and the contraction part is used to contract the shape of the core mechanism 7 to reduce the contact area between the core mechanism 7 and the parts, so as to facilitate the ejection part to perform rapid ejection;

[0045] The utility model provides a mold forming device for mechanical parts driving an ejection mechanism. Specifically, during use, according to Figure 1 As shown, first, the entire device needs to be supported by the support seat on the entire support base 1, and then the entire device is connected to an external power supply, so that the entire device can perform injection molding normally, and the telescopic cylinder or automatic telescopic rod on the entire driving mechanism 3 is controlled to drive the upper mold mechanism 5 to descend, and the top of the lower mold mechanism 6 is sealed. After that, the injection molding solution is added to the interior of the lower mold mechanism 6, and after it is cooled, a mechanical component with the same structure as the outside of the core mechanism 7 is obtained inside the lower mold mechanism 6. After that, the ejection mechanism 8 is controlled to start working, and the outer side of the top of the core mechanism 7 is reduced by the contraction part on the ejection mechanism 8, and then the upper and lower telescopic work of the ejection part is coordinated, so that the mold can be ejected, and the injection molding of the mechanical component can be completed.

[0046] according to Figure 1 As shown, the upper mold mechanism 5 is composed of an upper mold baffle 51 and a feed port 52, and the position of the upper mold baffle 51 corresponds to the position of the lower mold mechanism 6, and is used to seal the top of the lower mold mechanism 6. At the same time, the feed port 52 is set at the outer side of the top of the upper mold baffle 51, and is used to connect with the external feeding pipe, and is used to fill the solution into the lower mold mechanism 6.

[0047] Specifically, since the interior of the upper mold baffle 51 and the feed port 52 are mutually interpenetrating, and a liquid outlet of the same size as the feed port 52 is also provided at the bottom of the upper mold baffle 51, when the upper mold baffle 51 and the top of the lower mold mechanism 6 are in a sealed environment, it is only necessary to perform solution filling work at the position of the feed port 52 to achieve the solution filling work of the interior of the lower mold mechanism 6.

[0048] according to Figure 2-4As shown, the core mechanism 7 is arranged in a rectangular structure as a whole, and is composed of a side block 71 and a protruding block 72. The bottom of the side block 71 is connected to the horizontal workbench on the support base 1, and the protruding block 72 is in contact with the horizontal workbench on the support base 1. There are four side blocks 71 and four protruding blocks 72 respectively. The side block 71 is in a rectangular horizontal position, and the protruding block 72 is in a rectangular right-angle position. The top of the protruding block 72 is connected to an ejection mechanism 8, and the ejection mechanism 8 is arranged in the middle position of the lower mold mechanism 6. A sliding protrusion is arranged on the outside of both sides of the protruding block 72, and a horizontal slide groove is also arranged on the outside of both sides of the side block 71, which is used for the sliding protrusion outside the protruding block 72 to slide inside it, so as to ensure that when the shrinking part controls the shrinkage, the protruding block 72 can move horizontally under the action of the slide groove and the sliding protrusion.

[0049] Specifically, since the core mechanism 7 is arranged in a rectangular structure, it has four protruding blocks 72 with direct corners, so when it is directly ejected through the traditional bottom ejection structure, a jamming phenomenon will occur. Since the ejection mechanism 8 is composed of an ejection part and a contraction part, the contraction part on the ejection mechanism 8 can first shrink the position of the protruding block 72 inward, and then the ejection work is performed through the ejection part, so there will be no ejection jamming phenomenon.

[0050] In this embodiment, the core mechanism 7 can also be a larger hemispherical structure at the top. By connecting the contraction part with the four vertices of the hemispherical structure, the effect of controlling the positions of the four vertices to contract can be achieved, which is convenient for subsequent direct ejection work.

[0051] according to Figure 2 and Figure 5-7 As shown, the ejection mechanism 8 includes:

[0052] A control cylinder 81 is located below the horizontal workbench supporting the base 1;

[0053] The push rod 82 is a cylindrical structure, and its bottom is connected to the top of the control cylinder 81. The vertical center axis of the push rod 82 is in line with the center axis of the lower mold mechanism 6.

[0054] The ejector portion includes a connecting rod 83 and an ejector block 84. One end of the connecting rod 83 is arranged at the bottom of the ejector rod 82, and the other end is connected to the bottom of the ejector block 84. The ejector block 84 is arranged in an annular structure and is located in the middle of the horizontal workbench of the support base 1 and is flush with it.

[0055] The contraction part includes a rotating rod 85 and a fixed block 86. The rotating rod 85 is used to connect the top rod 82 and the fixed block 86, and the rotating rod 85 is axially connected to both of them. The top end of the fixed block 86 is connected to the inner side of the protruding block 72;

[0056] Specifically, when it is necessary to eject the mechanical parts, the control cylinder 81 is started to move upward, and then it drives the ejector rod 82 at its top to move upward. First, since the outside of the ejector rod 82 is connected to the rotating rod 85 through the connecting shaft, and the other end of the rotating rod 85 is connected to the external shaft of the fixed block 86, the fixed block 86 will be pulled to move. Since the fixed block 86 is connected to the top of the protruding block 72, and the protruding block 72 is restricted by the slide groove and the sliding protrusion, it cannot rise and can only move inward, so the protruding block 72 can shrink to the center position. At this time, the protruding block 72 does not contact each other with the cooled molding mold. When the ejector rod 82 moves upward, due to the setting of the connecting rod 83, it will also drive the ejection block 84 at its top to move upward, thereby pushing the entire mold to demould.

[0057] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
