Description

Technical Field

[0001] This utility model belongs to the field of injection mold technology and relates to a multi-point injection mold for wardrobe guard rings. Background Technology

[0002] Wardrobe guards are a common product used extensively in wardrobe structures. Their main function is to protect critical wardrobe components from damage, thus extending the wardrobe's lifespan. Guards are typically made of rubber or silicone and provide protection, shock absorption, fixation, and insulation. Therefore, they can be produced using injection molding. The raw material is heated to a molten state and then injected into a pre-designed molding cavity. Once the cavity is full, the mold is rapidly cooled, causing the material to solidify and form the desired product. Injection molding for wardrobe guard production offers advantages such as high precision and high efficiency.

[0003] However, existing injection molds used for producing wardrobe guard rings still have some shortcomings. Due to the large size of wardrobes, the length of the matching guard rings is correspondingly long. In the structure of injection molds, multiple nozzles are usually used to feed material into the molding cavity at the same time. However, the amount of material fed into the nozzles cannot be adjusted according to the needs. Since the molding cavity of the guard ring is relatively long and narrow, the nozzles cannot complete the filling of the molding cavity at the same time. This will cause the molten liquid in some areas to cool down first, and the part filled later cannot be completely fused, resulting in layered peeling on the surface of the molded product and reducing the service life of the product. Summary of the Invention

[0004] The purpose of this utility model is to address the problems existing in the current technology by proposing a multi-point glue injection mold for wardrobe guard rings. The technical problem to be solved by this utility model is: how to control the amount of material fed into the molding cavity by the nozzle according to the material feeding requirements.

[0005] The objective of this utility model can be achieved through the following technical solution: A multi-point injection mold for wardrobe guard rings includes a top plate, a flow divider plate fixedly connected to the bottom of the top plate, a fixed template fixedly connected to the bottom of the flow divider plate, a slidingly connected movable template at the bottom of the fixed template, a fixed foot plate at the bottom of the movable template, an annular molding cavity between the fixed template and the movable template, a feed inlet on the top plate, a flow divider mechanism connected to the feed inlet inside the flow divider plate, a flow divider channel inside the flow divider mechanism, a plurality of nozzles at the bottom of the flow divider mechanism, the bottom of each nozzle being inserted into the molding cavity, one end of the flow divider channel being connected to the feed inlet, and the other end being connected to the nozzle, and a plurality of knobs for adjusting the flow rate inside the flow divider mechanism.

[0006] In this solution, the raw material is heated to a molten state and injected into the inlet, then flows into the bottom distribution channel. After being divided by the distribution channel, it flows evenly into the nozzles connected to the bottom. The molten liquid is simultaneously injected into the annular molding cavity through the nozzles, and then cooled and shaped in the molding cavity to form the wardrobe guard ring. Finally, the mold is opened and the guard ring is removed to complete the injection molding. Through the above method, when some nozzles fill the molding cavity too quickly or too slowly, the flow rate inside the distribution channel can be adjusted by the knob to allow each nozzle to receive an appropriate amount of molten liquid, so that the molding cavity at the bottom can be filled evenly, and the molten liquid can better merge and fuse inside the molding cavity to form a wardrobe guard ring product with higher precision and longer service life.

[0007] In the aforementioned multi-point injection mold for wardrobe retaining rings, the flow distribution mechanism is in the form of two connected "+" shapes. The nozzle is located below the end of the flow distribution mechanism, and the feed port is connected to the center of the flow distribution mechanism. The "+" structure facilitates the distribution of molten liquid from the middle to each end, making the flow rate inside the distribution channel more uniform and facilitating the injection of molten liquid into various parts of the annular molding cavity.

[0008] In the aforementioned multi-point injection mold for wardrobe retaining rings, the upper and lower sides of the flow distribution mechanism are respectively provided with coil grooves for placing heating wires, and one side of the flow distribution plate is provided with several wiring ports. The coil grooves are used to place heating wires, which heat the molten liquid and maintain its fluidity. The heating wires are connected to the wiring ports to supply power to the heating wires.

[0009] In the aforementioned multi-point glue-injection injection mold for wardrobe retainers, the fixed mold plate has a placement groove inside, and a detector is installed inside the placement groove. The detector is connected to the nozzle. The detector is used to detect the temperature of the molten liquid inside the nozzle and to prevent clogging inside the nozzle.

[0010] In the aforementioned multi-point injection mold for wardrobe retainers, the moving mold plate is provided with several downwardly recessed molding grooves, which are located at the bottom of the molding cavity. The molding grooves are connected to the molding cavity, and the molten metal can be filled into the molding grooves together, forming an integrally connected strip-shaped reinforcing rib structure at the bottom of the retainer, thereby improving the structural strength of the retainer.

[0011] In the aforementioned multi-point injection mold for wardrobe guard rings, a slidingly connected push plate is provided on the inner side of the foot plate. A fixed ejector pin is provided on the push plate, with one end of the ejector pin slidably passing through the moving mold plate and extending to the bottom of the molding cavity. After the moving mold plate moves to open the mold, it pushes the push plate to one side of the moving mold plate. The push plate then drives the ejector pin to extend from the bottom of the molding cavity, ejecting the molded guard ring product and demolding it.

[0012] In the aforementioned multi-point injection mold for wardrobe retainers, the fixed and moving mold plates are equipped with several cooling channels located on the upper and lower sides of the molding cavity. Coolant is injected into the cooling channels to rapidly cool the molding cavity, thereby increasing the speed of retainer shaping and improving production efficiency.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. In this solution, when some nozzles fill the molding cavity too quickly or too slowly, the flow rate inside the distribution channel can be adjusted by turning the knob, so that each nozzle flows in an appropriate amount of melt, which can evenly fill the molding cavity at its bottom, allowing the melt to better merge and fuse inside the molding cavity, forming a wardrobe guard ring product with higher precision and longer service life.

Detailed Implementation

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] Example

[0022] like Figure 1As shown, a multi-point injection mold for wardrobe guard rings includes a top plate 1, a flow divider plate 2 fixedly connected to the bottom of the top plate 1, a fixed template 3 fixedly connected to the bottom of the flow divider plate 2, a slidingly connected movable template 4 at the bottom of the fixed template 3, a foot plate 5 fixedly connected to the bottom of the movable template 4, a feed inlet 1a on the top plate 1, a wiring port 2a on one side of the flow divider plate 2, several cooling channels 3a on the side walls of the fixed template 3 and the movable template 4, and a reciprocating push plate 5a on the inner side of the foot plate 5.

[0023] like Figure 2 As shown, a forming cavity 7 is provided between the fixed template 3 and the moving template 4. The cooling channel 3a is provided on the upper and lower sides of the forming cavity 7. The flow divider 2 is provided with a flow divider mechanism 6 connected to the feed inlet 1a. The bottom of the flow divider mechanism 6 is provided with a plurality of nozzles 6b. The bottom of the nozzles 6b is inserted into the forming cavity 7 respectively. The flow divider mechanism 6 is provided with a flow divider channel 6a. One end of the flow divider channel 6a is connected to the feed inlet 1a and the other end is connected to the nozzles 6b. The pusher plate 5a is provided with a fixed ejector pin 5b.

[0024] like Figure 3 As shown, the diversion mechanism 6 is in the shape of two connected "+" shapes. The nozzle 6b is located below the end of the diversion mechanism 6. The feed inlet 1a is connected to the center of the diversion mechanism 6. The diversion mechanism 6 is provided with several knobs 6c for adjusting the flow rate inside the diversion channel 6a. The upper and lower sides of the diversion mechanism 6 are respectively provided with coil grooves 6d for placing heating wires. The fixed template 3 is provided with a placement groove 3b. The placement groove 3b is provided with a detector 3c. The detector 3c is connected to the nozzle 6b.

[0025] like Figure 4 As shown, the molding cavity 7 has an annular structure, and the moving template 4 is provided with a plurality of downwardly recessed molding grooves 4a. The molding grooves 4a are located at the bottom of the molding cavity 7, and one end of the ejector pin 5b slides through the moving template 4 and extends to the bottom of the molding cavity 7.

[0026] The working principle of this solution is as follows: Figure 1-4As shown, the raw material is heated to a molten state and injected into the feed port 1a, then flows into the bottom distribution channel 6a. After being divided by the distribution channel 6a, it flows evenly into the nozzle 6b connected to the bottom. The molten liquid is simultaneously injected into the annular molding cavity 7 through the nozzle 6b, and then cooled and shaped in the molding cavity 7 to form the wardrobe guard ring. Finally, the moving template 4 is moved to open the mold, pushing the push plate 5a to one side of the moving template 4. The push plate 5a drives the ejector pin 5b to extend from the bottom of the molding cavity 7, ejecting the molded guard ring product out of the mold. When some nozzles 6b fill the molding cavity 7 too quickly or too slowly, the flow rate inside the distribution channel 6a can be adjusted by the knob 6c to ensure that each nozzle 6b receives an appropriate amount of molten liquid, so that the molding cavity 7 at its bottom can be filled evenly. This allows the molten liquid to better merge and fuse inside the molding cavity 7, forming a wardrobe guard ring product with higher precision and longer service life.
