Description

Technical Field

[0001] This utility model relates to the field of epoxy resin mold technology, specifically a combined epoxy resin mold that facilitates batch demolding. Background Technology

[0002] A resin mold is a tool used to make resin products. By pouring resin into the mold and allowing it to cure for a certain period of time, a resin product of the desired shape can be obtained.

[0003] According to the patent titled "Bionic Demolding Device for Epoxy Resin Molds" (Patent Publication No.: CN111619056A, Patent Publication Date: 2020-09-04), the device includes an inner core seat and a driving structure. Two pincers are pivotally connected to the inner core seat, symmetrically arranged about the central axis of the inner core seat. Each pincer has a needle-like tip, which bends at an angle towards the other pincer. The driving structure drives the two pincers to rotate synchronously around their pivot point with the inner core seat, opening and closing. Compared with existing technologies, this device utilizes the principle of biomimetic insect mouthparts, offering advantages such as strong locking ability with soft rubber products and low energy consumption.

[0004] Based on the aforementioned existing technology, current combined epoxy resin molds still have the following problems: after the epoxy resin cures, especially for molds with complex shapes, deep cavities, smooth surfaces, or fine textures, the product will adhere tightly to the inner wall of the mold due to material shrinkage, surface adhesion, and slight chemical adhesion. Manual demolding requires great patience and skill, often involving prying and tapping with tools, which is very laborious and inefficient. Therefore, this utility model provides a combined epoxy resin mold that facilitates batch demolding. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a modular epoxy resin mold that facilitates batch demolding. It solves the following problems associated with existing modular epoxy resin molds: after the epoxy resin cures, especially for molds with complex shapes, deep cavities, smooth surfaces, or fine textures, the product tends to adhere tightly to the inner wall of the mold due to material shrinkage, surface adhesion, and slight chemical adhesion. Manual demolding requires considerable patience and skill, often involving prying and tapping with tools, which is extremely laborious and inefficient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a combined epoxy resin mold for easy batch demolding, comprising a worktable, wherein a demolding mechanism is provided above the worktable for rapid batch demolding, and the demolding mechanism includes:

[0007] The vibration unit is located above the workbench and includes a fixed frame fixedly installed at the bottom of the workbench. A left rotating shaft is rotatably installed on the left side of the fixed frame, and a right rotating shaft is rotatably installed on the right side. A fixed frame is fixedly installed between the right rotating shaft and the fixed frame, and a template is fixedly installed inside the fixed frame. An installation frame is fixedly installed between the left and right rotating shafts inside the fixed frame, and a set of limiting rails is symmetrically fixedly installed inside the installation frame. A sliding rod is slidably installed inside the limiting rails, and several support plates are fixedly installed on the top of the sliding rod. Several impact columns are fixedly installed on the top of the support plates. The sliding rod is driven to move up and down by the drive assembly, so that the impact columns impact the template to generate vibration and achieve rapid batch demolding.

[0008] The rotation positioning unit is located on the left side of the vibration unit and is used to fix the position of the fixed frame after it rotates 180 degrees.

[0009] Preferably, a rubber pad is fixedly installed on the top of the impact column to reduce the impact noise when the impact column hits the template.

[0010] Preferably, a handle is fixedly installed at the left end of the left rotating shaft through the fixing frame, which is used to drive the fixing frame and the template to rotate through the left rotating shaft.

[0011] Preferably, the drive assembly includes a linkage groove formed on the front side of the sliding rod, a fixing plate is fixedly installed on the top of the inner cavity of the fixing frame, a motor is fixedly installed on the front side of the fixing plate, a rotating rod is fixedly installed through the linkage groove at the output end of the motor, and a linkage column is fixedly installed above one side of the rotating rod, and the linkage column is located inside the linkage groove for sliding.

[0012] Preferably, the rotary positioning unit includes a mounting box fixedly installed inside the throttle, a return spring fixedly installed inside the mounting box, a sliding groove on one side of the mounting box, a plug slidably installed inside the mounting box, and a pull rod fixedly installed on one side of the plug, with the pull rod located inside the sliding groove for sliding adaptation.

[0013] Preferably, the fixing frame has a set of insertion holes on the left side, and the insertion post is slidably inserted into the insertion hole to fix the position of the left rotating shaft.

[0014] This invention provides a modular epoxy resin mold that facilitates batch demolding. Compared with the prior art, it has the following advantages:

[0015] 1. This modular epoxy resin mold, which facilitates batch demolding, is equipped with a vibration unit. When the motor runs, it drives the rotating rod to rotate. The rotating rod drives the linkage column to slide back and forth inside the linkage groove, thereby driving the sliding rod to move up and down back and forth. The sliding rod drives the support plate to move synchronously. The support plate drives the impact column to repeatedly impact the template to generate vibration, which effectively breaks the adhesion between the product and the inner wall of the mold, so that the cured product and the mold have a slight relative displacement, reducing demolding resistance and making it easier and more convenient to remove the product from the mold.

[0016] 2. This modular epoxy resin mold, which facilitates batch demolding, is equipped with a rotary positioning unit. When the user pulls the lever, the insert slides out from the front insertion hole. By rotating the handle, the fixed frame and the template rotate 180 degrees through the left rotating shaft. The return spring pushes the insert through its own elasticity, causing the insert to slide into the rear insertion hole, thereby fixing the position of the fixed frame and the template. This allows the template to face downwards, and the product's own gravity enables better demolding. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] A modular epoxy resin mold for easy batch demolding includes a worktable 1, and a demolding mechanism 2 is provided above the worktable 1 for rapid batch demolding. The demolding mechanism 2 includes:

[0025] The vibration unit 21 is located above the workbench 1 and includes a fixed frame 211 fixedly installed at the bottom of the workbench 1. A left rotating shaft 212 is rotatably installed on the left side of the fixed frame 211, and a right rotating shaft 213 is rotatably installed on the right side. The fixed frame 214 is fixedly installed between the right rotating shaft 213 and the fixed frame 214. A template 215 is fixedly installed inside the fixed frame 214. An installation frame 216 is fixedly installed between the left rotating shaft 212 and the right rotating shaft 213 inside the fixed frame 211. A set of limiting rails 217 are symmetrically fixedly installed inside the installation frame 216. A sliding rod 218 is slidably installed inside the limiting rails 217. Several support plates 219 are fixedly installed on the top of the sliding rod 218. Several impact columns 2110 are fixedly installed on the top of the support plates 219. The sliding rod 218 is driven to move up and down by the drive assembly 3 so that the impact columns 2110 impact the template 215 to generate vibration and achieve rapid batch demolding.

[0026] The rotation positioning unit 22 is located on the left side of the vibration unit 21 and is used to fix the position of the fixed frame 214 after it rotates 180 degrees.

[0027] Motor 33 is a three-phase asynchronous motor with a self-locking function. It is electrically connected to an external power supply and can be opened and closed through a human-operated control panel. Motor 33 drives the sliding rod 218 to move up and down, which drives the impact column 2110 to impact the template 215 at high frequency to generate vibration. This effectively breaks the adhesion between the epoxy resin product and the inner wall of the mold, enabling batch and rapid demolding, significantly improving efficiency and reducing the difficulty of manual operation.

[0028] In this embodiment, a rubber pad is fixedly installed on the top of the impact column 2110 to reduce the impact sound when the impact column 2110 impacts the template 215.

[0029] The rubber pads cushion the impact force, significantly reducing noise pollution during the demolding process, improving the working environment, and preventing hard impacts from damaging the mold surface.

[0030] In this embodiment, the left end of the left rotating shaft 212 is fixedly installed with a handle 2111 through the fixing frame 211, which is used to drive the fixing frame 214 and the template 215 to rotate through the left rotating shaft 212.

[0031] The 2111 throttle design provides convenient manual rotation control, directly driving the mold frame and template to rotate via the left swivel, simplifying the operation process and improving the flipping efficiency.

[0032] In this embodiment, the drive assembly 3 includes a linkage groove 31 opened on the front side of the sliding rod 218, a fixing plate 32 fixedly installed on the top of the inner cavity of the fixing frame 211, a motor 33 fixedly installed on the front side of the fixing plate 32, a rotating rod 34 fixedly installed through the linkage groove 31 at the output end of the motor 33, and a linkage column 35 fixedly installed on the upper side of one side of the rotating rod 34, and the linkage column 35 is located inside the linkage groove 31 for sliding.

[0033] The sliding engagement between the linkage groove 31 and the linkage column 35 converts the rotational motion of the motor 33 into the precise reciprocating linear motion of the sliding rod 218, ensuring that the impact column 2110 transmits vibration to the template 215 stably and efficiently, making the demolding action reliable and energy-efficient.

[0034] In this embodiment, the rotary positioning unit 22 includes a mounting box 221 fixedly mounted inside the throttle 2111. A return spring 222 is fixedly mounted inside the mounting box 221, and a sliding groove 223 is provided on one side of the mounting box 221. A plug 224 is slidably mounted inside the mounting box 221, and a pull rod 225 is fixedly mounted on one side of the plug 224. The pull rod 225 is located inside the sliding groove 223 and is adapted to slide. A set of insertion holes 226 are provided on the left side of the fixing bracket 211, and the plug 224 is slidably inserted into the insertion holes 226 to fix the position of the left rotating shaft 212.

[0035] The reset spring 222 automatically pushes the insert post 224 into the insertion hole 226, realizing one-click locking after the mold is flipped 180 degrees. The operation is simple, the positioning is firm, and the mold shakes during demolding.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] During operation, the user first pulls the lever 225, causing the insert 224 to slide out from the front insertion hole 226. Then, the user rotates the handle 2111, which drives the fixed frame 214 and the template 215 to rotate 180 degrees through the left rotating shaft 212. The return spring 222 pushes the insert 224 with its own elasticity, causing the insert 224 to slide into the rear insertion hole 226, fixing the position of the fixed frame 214 and the template 215 so that the template 215 faces downward.

[0038] Then, the motor 33 runs, driving the rotating rod 34 to rotate. The rotating rod 34 drives the linkage column 35 to slide back and forth inside the linkage groove 31, thereby driving the sliding rod 218 to move up and down back and forth. The sliding rod 218 drives the support plate 219 to move synchronously. The support plate 219 drives the impact column 2110 to repeatedly impact the template 215 to generate vibration for rapid demolding.
