Description

Technical Field

[0001] This utility model relates to the field of injection molding equipment, and in particular to a demolding device for injection molds based on the production of biomimetic fish bait. Background Technology

[0002] Injection molds are tools for producing plastic products, and also tools for giving plastic products a complete structure and precise dimensions. Injection molding involves injecting heated and molten plastic into the mold cavity under high pressure from an injection molding machine. After cooling and solidification, the molded product is obtained. Injection molds consist of two parts: a moving mold and a fixed mold. During injection molding, the moving mold and the fixed mold close to form the gating system and the cavity. When the mold is opened, the moving mold and the fixed mold separate to remove the plastic product.

[0003] However, during injection molding, plastic fragments are easily left in the mold grooves. Existing demolding devices can only remove the plastic product during use, and it is difficult to clean the inside of the mold grooves.

[0004] Furthermore, existing demolding devices are difficult to compensate for wear. Over time, gaps will form between the moving mold and the fixed mold due to wear, which will cause burrs on the edges of the injection molded products, increasing the difficulty of subsequent processing and affecting the efficiency of injection molding.

[0005] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a demolding device for injection molds based on the production of biomimetic fish bait, so as to solve the technical defects mentioned in the background art.

[0007] The purpose of this utility model can be achieved through the following technical solution: a demolding device for injection molds based on biomimetic fish bait production, including a fixed mold and a moving mold, both of which have grooves, and also includes a fixed plate, the moving mold being movably connected to the fixed plate, and a demolding component being fixedly installed on the fixed plate;

[0008] The demolding assembly includes an airbag and a crossbar. The airbag and the crossbar are fixedly mounted on a fixed plate. A through hole is provided on the moving mold. The crossbar is movably mounted in the through hole. A cavity is provided inside the crossbar. An air vent is provided on the crossbar. The airbag is fixedly connected to the crossbar.

[0009] The demolding assembly also includes a cylinder, which is fixedly mounted on the fixed mold. A locking block is fixedly mounted on the top output end of the cylinder, and the locking block is located above the fixed mold and the moving mold.

[0010] Preferably, an electric push rod is fixedly installed on the side of the fixed plate away from the moving mold, a connecting plate is fixedly connected to the output end of the electric push rod, and a connecting rod is fixedly installed on the side of the connecting plate close to the fixed plate.

[0011] Preferably, the connecting rod is movably connected to the fixed plate, and the connecting rod passes through the fixed plate and is fixedly connected to the moving mold.

[0012] Preferably, a fixing tube is fixedly installed on the side of the fixing plate near the moving mold. The fixing tube has a cavity inside. The fixing tube is fixedly connected to the crossbar. The airbag is fixedly connected to the fixing tube through a pipeline.

[0013] Preferably, multiple crossbars are provided, and the crossbars are evenly spaced on the fixed tube.

[0014] Preferably, a guide rod is fixedly installed on the fixed plate, and positioning holes are opened at the four corners of the moving mold, with one end of the guide rod movably installed in the positioning hole.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) This utility model uses the combination of airbag and crossbar. After injection molding is completed, the moving mold moves. At this time, the crossbar gradually extends out of the through hole and pushes the plastic product to fall. While the moving mold moves, it gradually squeezes the airbag. The gas in the airbag enters the crossbar and is ejected from the air outlet. The high-speed airflow causes the plastic stuck in the groove to fall off, thereby achieving rapid cleaning of the groove.

[0017] (2) This utility model uses the cylinder and the clamping block in combination. After the moving mold and the fixed mold are attached, the cylinder is started to drive the clamping block to move down until the clamping block is engaged with one side of the moving mold. The clamping block applies a squeezing force to the moving mold, thereby making the moving mold and the fixed mold fit more tightly, thus compensating for wear and effectively improving the efficiency of injection molding.

[0025] 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.

[0026] Example 1: This example is used to solve the problem that plastic fragments are easily left in the mold groove during injection molding, and the demolding device in the prior art can only remove the plastic product during use, but it is difficult to clean the inside of the mold groove.

[0027] Please see Figure 1 - Figure 4 As shown, this embodiment is a demolding device for injection molds based on biomimetic fish bait production, including a fixed mold 1 and a moving mold 2. Both the fixed mold 1 and the moving mold 2 are provided with grooves 101. It also includes a fixed plate 102. The moving mold 2 is movably connected to the fixed plate 102. A demolding component 3 is fixedly installed on the fixed plate 102.

[0028] The demolding assembly 3 includes an airbag 301 and a crossbar 302. The airbag 301 and the crossbar 302 are fixedly installed on the fixed plate 102. The moving mold 2 has a through hole 303. The crossbar 302 is movably installed in the through hole 303. The crossbar 302 has a cavity inside and an air outlet 304. The airbag 301 is fixedly connected to the crossbar 302.

[0029] An electric push rod 307 is fixedly installed on the side of the fixed plate 102 away from the moving mold 2. A connecting plate 308 is fixedly connected to the output end of the electric push rod 307. A connecting rod 309 is fixedly installed on the side of the connecting plate 308 close to the fixed plate 102. The connecting rod 309 is movably connected to the fixed plate 102. After passing through the fixed plate 102, the connecting rod 309 is fixedly connected to the moving mold 2. In actual use, the electric push rod 307 drives the connecting plate 308 to move, and then the connecting rod 309 drives the moving mold 2 to move.

[0030] A fixed tube 310 is fixedly installed on the side of the fixed plate 102 near the moving mold 2. The fixed tube 310 has a cavity inside. The fixed tube 310 is fixedly connected to the crossbar 302. The airbag 301 is fixedly connected to the fixed tube 310 through a pipeline. Multiple crossbars 302 are provided and are evenly distributed on the fixed tube 310. After the gas enters the cavity of the fixed tube 310, it flows into the fixed tube 310.

[0031] A guide rod 311 is fixedly installed on the fixed plate 102. The four corners of the moving mold 2 are provided with positioning holes. One end of the guide rod 311 is movably installed in the positioning hole. When the electric push rod 307 drives the moving mold 2 to move, the guide rod 311 slides in the positioning hole. Under the action of the guide rod 311, the moving mold 2 moves more stably and avoids the moving mold 2 from deviating.

[0032] When the injection molding is completed, the moving mold 2 moves. At this time, the crossbar 302 gradually extends out of the through hole 303. The crossbar 302 pushes the plastic product to fall off. While the moving mold 2 moves, it gradually squeezes the air bag 301. The gas in the air bag 301 enters the crossbar 302 and is ejected from the air outlet 304. The high-speed airflow causes the plastic stuck in the groove 101 to fall off, thereby cleaning the groove 101.

[0033] Example 2: This example is used to solve the problem that existing demolding devices are difficult to compensate for wear. After long-term use, gaps are generated between the moving mold and the fixed mold due to wear, which leads to burrs on the edges of the injection molded products, increases the difficulty of subsequent processing, and affects the efficiency of injection molding.

[0034] Please see Figure 5 As shown, this utility model also includes a cylinder 305, which is fixedly installed on the fixed mold 1. A locking block 306 is fixedly installed on the top output end of the cylinder 305. The locking block 306 is located above the fixed mold 1 and the moving mold 2. The bottom of the locking block 306 has a locking groove. When the inside of the locking groove is in contact with the top of the fixed mold 1 and the moving mold 2, the inner wall of one side of the locking groove abuts against the moving mold 2.

[0035] After the moving mold 2 and the fixed mold 1 are bonded together, the cylinder 305 is activated to drive the clamping block 306 to move down until the clamping block 306 is engaged with one side of the moving mold 2. The clamping block 306 applies a squeezing force to the moving mold 2, thereby making the moving mold 2 and the fixed mold 1 bond more tightly, thus compensating for wear and effectively improving the efficiency of injection molding.

[0036] Combining Embodiment 1 and Embodiment 2, through the coordinated use of airbag 301 and crossbar 302, after injection molding is completed, crossbar 302 gradually extends out from through hole 303, pushing the plastic product to fall off. At the same time, gas is ejected from air outlet 304, and the high-speed airflow causes the plastic adhering to the groove 101 to fall off, thereby achieving rapid cleaning of the groove 101. Meanwhile, after the moving mold 2 and fixed mold 1 are attached, cylinder 305 is activated to drive the locking block 306 to move down until the locking block 306 is engaged with one side of the moving mold 2. The locking block 306 applies a squeezing force to the moving mold 2, thereby making the moving mold 2 and fixed mold 1 fit more tightly, thereby compensating for wear and effectively improving the efficiency of injection molding.

[0037] The working process and principle of this utility model are as follows:

[0038] First, through the combined use of airbag 301 and crossbar 302, after injection molding is completed, crossbar 302 gradually extends out of through hole 303, and plastic products are pushed off by crossbar 302. At the same time, gas is ejected from air outlet 304, and plastic stuck in groove 101 is removed by high-speed airflow, thereby achieving rapid cleaning of groove 101.

[0039] Furthermore, after the moving mold 2 and the fixed mold 1 are bonded together, the cylinder 305 is activated to drive the clamping block 306 to move down until the clamping block 306 engages with one side of the moving mold 2. The clamping block 306 applies a squeezing force to the moving mold 2, thereby making the moving mold 2 and the fixed mold 1 fit more tightly, thus compensating for wear and effectively improving the efficiency of injection molding.

[0040] In other words, the present invention, through the set demolding component 3, not only achieves rapid cleaning of the groove 101, but also effectively improves the injection molding efficiency.

[0041] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
