Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a high-precision positioning mold blank guide post device. Background Technology

[0002] In modern industrial production, molds are widely used in various manufacturing fields, and their precision directly affects product quality and production efficiency. As a key component of the mold, the precision positioning pin plays a crucial role in ensuring accurate positioning of the mold during the processing.

[0003] However, in the existing technology, the guide sleeve and the guide pillar are often connected by interference fit or fastening, which requires special tools for disassembly and may even require damage to the connection, increasing the difficulty and cost of maintenance. Due to the difficulty in disassembling the guide sleeve, cleaning, inspection or replacement of the guide sleeve becomes cumbersome, affecting the regular maintenance and upkeep of the mold. Utility Model Content

[0004] The purpose of this invention is to solve the problem of the guide post sleeve being inconvenient to disassemble in the existing technology, and to propose a high-precision positioning mold blank guide post device.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: it includes a lower mold, on which four sets of guide post sleeves are provided, each guide post having a sliding guide post inside, and an upper mold being slidably connected to each guide post. An injection port is provided at the top of the lower mold, and an installation component is provided between the lower mold and the guide post sleeves. The guide post sleeves are connected to the lower mold through the installation component, and an adjustment component is provided between the guide posts and the upper mold. The adjustment component is used to adjust the working height of the guide posts.

[0006] Preferably, the mounting assembly includes four sets of limiting grooves formed on the surface of the lower mold. Each limiting groove has a sliding limiting block, and each limiting block has a guide post sleeve fixedly connected to its outer wall. Both sides of the lower mold have spring grooves, and each spring groove has a spring on its inner wall. The other end of each spring is fixedly connected to a sliding rod, which slides within the spring groove. Each sliding rod has a pull rod at its top, and each pull rod has a plug at its front and rear ends. Each guide post sleeve has a socket on its outer wall, and the plug and socket are slidably connected.

[0007] Preferably, the plug is L-shaped, and the socket has a countersunk hole that matches part of the plug.

[0008] Preferably, the pull rod is cylindrical in shape, and the outer wall of the pull rod is provided with anti-slip texture.

[0009] Preferably, the adjustment assembly includes four sets of driven wheels threaded onto the guide post. Each driven wheel has a belt on its outer wall. A bracket is provided on the upper mold surface between two sets of driven wheels. A motor is provided on the top of each bracket. A drive wheel is provided at the bottom of each motor. The outer wall of the drive wheel is in contact with the belt surface.

[0010] Preferably, the outer walls of both the driven wheel and the driving wheel are polished, and the inner wall of the belt is tightly fitted to the outer walls of the driven wheel and the driving wheel.

[0011] Preferably, the motor has a built-in wireless module, and the motor input terminal is wirelessly connected to the controller via the wireless module.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the guide sleeve is driven to slide linearly in the limiting groove by the limiting block and fit against the bottom of the limiting groove. At this time, the socket and the plug are aligned. Then, the spring's restoring force drives the sliding rod to slide back in the spring groove, and the sliding rod drives the plug to insert into the socket, thereby installing the guide sleeve. When it is necessary to replace the damaged guide sleeve, pull the pull rod, which drives the sliding rod to slide in the spring groove and stretches the spring until the plug slides out of the socket. Then, the guide sleeve drives the limiting block to slide out of the limiting groove, which allows for quick disassembly of the guide sleeve. This facilitates quick disassembly and assembly of the guide sleeve by the staff, thereby reducing the difficulty of later maintenance and cleaning of the guide sleeve.

[0014] 2. In this utility model, the motor drives the drive wheel to rotate, which in turn drives two sets of driven wheels to rotate on the guide post via a belt. At the same time, the driven wheels continuously press the upper mold, causing the upper mold to slide on the guide post until the distance between the upper mold and the lower mold is adjusted to a suitable position. Then the motor can be turned off, which makes it easier for the operator to control the distance between the upper mold and the lower mold, and also makes it easier for the operator to adjust the height of the guide post.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example

[0023] like Figure 1-4 As shown, this utility model provides a high-precision positioning mold blank guide post device, including a lower mold 1, four sets of guide post sleeves 2 on the lower mold 1, guide posts 3 sliding inside each guide post sleeve 2, and an upper mold 4 slidingly connected to each guide post 3. An injection port 5 is opened at the top of the lower mold 1. An installation component 6 is provided between the lower mold 1 and the guide post sleeves 2. The guide post sleeves 2 are connected to the lower mold 1 through the installation component 6. An adjustment component 7 is provided between the guide posts 3 and the upper mold 4. The adjustment component 7 is used to adjust the working height of the guide posts 3.

[0024] like Figure 2 and Figure 3 As shown, the mounting component 6 includes four sets of limiting grooves 61 set on the surface of the lower mold 1. Each limiting groove 61 has a sliding limiting block 62. Each limiting block 62 has a guide post sleeve 2 fixedly connected to its outer wall. Each side of the lower mold 1 has a spring groove 63. Each spring groove 63 has a spring 64 on its inner wall. Each spring 64 has a sliding rod 65 fixedly connected to its other end. The sliding rod 65 slides in the spring groove 63. Each sliding rod 65 has a pull rod 66 at its top. Each pull rod 66 has a plug 67 at its front and rear ends. Each guide post sleeve 2 has a socket 68 on its outer wall. The plug 67 and the socket 68 are slidably connected.

[0025] The guide sleeve 2 is driven to slide linearly in the limiting groove 61 by the limiting block 62 and fit against the bottom of the limiting groove 61. At this time, the socket 68 and the plug 67 are aligned. Then, the restoring force of the spring 64 drives the slide rod 65 to slide back in the spring groove 63 and causes the slide rod 65 to drive the plug 67 into the socket 68, thereby installing the guide sleeve 2. When the damaged guide sleeve 2 needs to be replaced, pull the pull rod 66, which drives the slide rod 65 to slide in the spring groove 63 and stretches the spring 64 until the plug 67 slides out of the socket 68. Then, the guide sleeve 2 drives the limiting block 62 to slide out of the limiting groove 61, which allows the guide sleeve 2 to be quickly disassembled. This makes it easier for workers to quickly disassemble and install the guide sleeve 2, thereby reducing the difficulty of later maintenance and cleaning of the guide sleeve 2.

[0026] like Figure 2 As shown, the plug 67 is designed in an L shape, and the socket 68 has a countersunk hole that matches part of the plug 67. This allows the operator to pull the plug 67, causing the plug 67 to slide the slide rod 65 in the spring groove 63 and slide the plug 67 out of the socket 68, thereby releasing the limiting position of the guide sleeve 2.

[0027] like Figure 2 As shown, the pull rod 66 has a cylindrical design and the outer wall of the pull rod 66 is provided with anti-slip texture, which can increase the friction of the staff holding the pull rod 66, so that the pull rod 66 can drive the two sets of plugs 67 to slide out of the socket 68.

[0028] like Figure 1 As shown, the adjustment assembly 7 includes four sets of driven wheels 71 threadedly connected to the guide post 3. Each driven wheel 71 has a belt 72 on its outer wall. Each set of driven wheels 71 has a bracket 73 on the surface of the upper mold 4 between the two sets of driven wheels 71. Each bracket 73 has a motor 74 on its top. Each motor 74 has a drive wheel 75 at its bottom. The outer wall of the drive wheel 75 is in contact with the surface of the belt 72.

[0029] The motor 74 drives the drive wheel 75 to rotate, which in turn drives two sets of driven wheels 71 to rotate threaded on the guide post 3 via the belt 72. At the same time, the driven wheels 71 continuously press the upper mold 4, causing the upper mold 4 to slide on the guide post 3 until the distance between the upper mold 4 and the lower mold 1 is adjusted to a suitable position. Then the motor 74 can be turned off, which makes it easier for the operator to control the distance between the upper mold 4 and the lower mold 1, and also makes it easier for the operator to adjust the height of the guide post 3.

[0030] like Figure 1 As shown, the outer walls of both the driven wheel 71 and the driving wheel 75 are polished. The inner wall of the belt 72 is tightly fitted with the outer walls of the driven wheel 71 and the driving wheel 75, which can increase the friction between the driven wheel 71 and the driving wheel 75 and the belt 72, thereby improving the rotation efficiency of the driving wheel 75 driving the driven wheel 71 to rotate through the belt 72.

[0031] like Figure 1 As shown, the motor 74 has a built-in wireless module. The input end of the motor 74 is wirelessly connected to the controller through the wireless module, which makes it convenient for staff to operate the motor 74 remotely through the controller and prevents the wires from getting tangled and tripping the staff.

[0032] The usage and working principle of this device are as follows: First, pull the lever 66, causing it to slide the slide bar 65 within the spring groove 63, continuously stretching the spring 64 until the lever 66 drives the insert 67 out of the socket 68. Then, the guide post sleeve 2 drives the limiting block 62 out of the limiting groove 61. Next, slide the repaired guide post sleeve 2 into the limiting groove 61 through the limiting block 62, aligning the socket 68 with the insert 67. Then, release the lever 66. The restoring force of the spring 64 causes the slide bar 65 to return to its original position within the spring groove 63, and the slide bar 65 drives the insert 67 into the socket 68, thus achieving the purpose of maintaining and cleaning the guide post sleeve 2.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
