Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to an injection mold for toy production. Background Technology

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, automated operation, a wide variety of colors and shapes, shapes ranging from simple to complex, sizes ranging from large to small, precise product dimensions, easy product updates and replacements, and the ability to produce complex-shaped parts. Injection molding is suitable for mass production and molding processing fields such as complex-shaped products.

[0003] Existing molds, such as the one described in application number 201922155668.4, include a mold base and an upper mold base. A lower mold base and two drive motors are mounted on the top of the mold base. The drive motors are located on both sides of the lower mold base. A cavity is formed at the center of the top of the lower mold base. The output ends of both drive motors are connected to rotating shafts. A stainless steel screw is welded to one end of each rotating shaft. A discharge port is formed at the center of the top of the upper mold base. Threaded holes are formed on the screw hole base, and the two stainless steel screws are threaded into the two threaded holes respectively. This invention has a simple structure. The two drive motors can drive the two rotating shafts to rotate at a uniform speed, thereby causing the two stainless steel screws to rotate. This allows the upper mold base to move downwards at a uniform speed, preventing the upper mold base from impacting and damaging the lower mold base. It also ensures that the upper mold base is firmly pressed against the lower mold base, preventing displacement during injection molding and improving processing quality.

[0004] In the above application, the upper mold plate is moved downward by a drive motor through a screw threaded connection. The threaded connection method is prone to wear of the screw itself. After long-term use, misalignment is likely to occur when the mold is closed, which affects the quality of the finished product. Therefore, we propose an injection mold for toy production to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art where the upper mold plate is controlled by a drive motor through a screw threaded connection. This threaded connection method is prone to wear on the screw itself, and after long-term use, misalignment is likely to occur during mold closing, affecting the quality of the finished product. Therefore, this invention proposes an injection mold for toy production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an injection mold for toy production, comprising an integral structure and a liquid inlet structure, wherein the liquid inlet structure is located on one side of the outer surface of the integral structure near the front side;

[0007] The overall structure includes a base plate, with fixed plates fixedly connected to the top two sides of the base plate. An electric slide is fixedly installed on the inner surface of the fixed plate near the top. A connecting plate is fixedly connected to the outer surface of the electric slide. An air compressor is fixedly installed on the top two sides of the connecting plate. A connecting pipe is provided through the air outlet of the air compressor. A bracket is fixedly connected to the front and rear outer surfaces of the connecting plate. An air outlet pipe is provided through the outer surface of the bracket. An upper mold is fixedly connected to the opposite side of the two connecting plates.

[0008] Preferably, the interior of the connecting pipe is connected to the interior of the air outlet pipe.

[0009] Preferably, a feed pipe is provided through the top center of the upper mold, and a sealing cap is slidably connected to the inner surface of the feed pipe near the top.

[0010] Preferably, a lower mold is fixedly connected to the top center of the base plate, and a liquid outlet pipe is provided through the other outer surface of the lower mold near the rear side. Support legs are fixedly connected to the bottom two sides of the base plate at the front and rear positions.

[0011] Preferably, a sliding rod is fixedly connected to the inner bottom of the lower mold at the front and rear positions, a compression spring is sleeved on the outer surface of the sliding rod, and a groove is formed on the inner surface of the lower mold.

[0012] Preferably, a sealing plate is fixedly connected to the extended end of the slide rod, the outer surface of the sealing plate is slidably connected to the inner surface of the lower mold, one end of the compression spring is fixedly connected to the bottom surface of the sealing plate, and the other end of the compression spring is fixedly connected to the inner bottom of the lower mold.

[0013] Preferably, the liquid inlet structure includes a liquid inlet pipe, and a solenoid valve is fixedly installed on the outer surface of the liquid inlet pipe and the liquid outlet pipe. The interior of the liquid inlet pipe is connected to the interior of the lower mold.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, during use, the electric slide table eliminates the need to control the upper mold's up-and-down movement via a threaded rod and motor. The electric slide table and connecting plate work together to directly move the upper mold up and down, effectively preventing misalignment between the upper and lower molds and improving the quality of the finished product. Furthermore, the air compressor, connecting pipe, and air outlet pipe work together to cool the injection-molded product with air, allowing it to be removed by the user later.

[0016] 2. In this utility model, external coolant can enter the groove through the cooperation of the inlet pipe and the solenoid valve. The groove is located in the lower mold, which can reduce the temperature of the mold. After molding, the compression spring loses its binding force, and the slide rod and sealing plate can move upward by utilizing the elastic force of the compression spring. At the same time as moving upward, the product in the lower mold can be pushed out, making it easier for the user to remove. Attached Figure Description

[0022] 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.

[0023] 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.

[0024] Example 1, as Figures 1-4As shown, an injection mold for toy production includes an integral structure 1 and a liquid inlet structure 2. The liquid inlet structure 2 is located on one side of the outer surface of the integral structure 1 near the front. The integral structure 1 includes a base plate 101. Fixed plates 104 are fixedly connected to the top two sides of the base plate 101. An electric slide 114 is fixedly installed on the inner surface of the fixed plate 104 near the top. A connecting plate 113 is fixedly connected to the outer surface of the electric slide 114. An air compressor 115 is fixedly installed on the top two sides of the connecting plate 113. A connecting pipe 112 is provided through the air outlet of the air compressor 115. A bracket 111 is fixedly connected to the front and rear outer surfaces of the connecting plate 113. An air outlet pipe 110 is provided through the outer surface of the bracket 111. An upper mold 116 is fixedly connected to the opposite side of the two connecting plates 113.

[0025] The effect achieved by the entire embodiment 1 is as follows: Figure 1 and Figure 3 As shown, in actual use, there is no need to control the up and down movement of the upper mold 116 through the cooperation of the threaded rod and the motor. Instead, the electric slide table 114 is used as the power source, and the up and down movement of the upper mold 116 can be directly controlled through the cooperation of the connecting plate 113. This can effectively prevent misalignment between the lower mold 105 and the upper mold 116, ensuring that subsequent operations can proceed normally. Furthermore, through the cooperation of the air compressor 115, the connecting pipe 112, and the air outlet pipe 110, the molded toy can be cooled a second time, making it easier for the user to remove it, thus achieving an auxiliary function.

[0026] Example 2, as Figures 1-4 As shown, the interior of the connecting pipe 112 is connected to the interior of the vent pipe 110. A feed pipe 117 is installed through the top center of the upper mold 116. A sealing cap 118 is slidably connected to the inner surface of the feed pipe 117 near the top. A lower mold 105 is fixedly connected to the top center of the base plate 101. A liquid outlet pipe 103 is installed through the outer surface of the lower mold 105 near the rear. Support legs 102 are fixedly connected to the front and rear positions on both sides of the bottom of the base plate 101. Slide rods 108 are fixedly connected to the front and rear positions on both sides of the inner bottom of the lower mold 105. The outer surface of the slide rods 108... The face sleeve is equipped with a compression spring 107, and the inner surface of the lower mold 105 is provided with a groove 106. The extended end of the slide rod 108 is fixedly connected to a sealing plate 109. The outer surface of the sealing plate 109 is slidably connected to the inner surface of the lower mold 105. One end of the compression spring 107 is fixedly connected to the bottom surface of the sealing plate 109, and the other end of the compression spring 107 is fixedly connected to the inner bottom of the lower mold 105. The liquid inlet structure 2 includes a liquid inlet pipe 201. A solenoid valve 202 is fixedly installed on the outer surface of the liquid inlet pipe 201 and the liquid outlet pipe 103. The interior of the liquid inlet pipe 201 is connected to the interior of the lower mold 105.

[0027] The overall effect of Embodiment 2 is that, by setting the sealing cover 118, foreign objects from the outside are prevented from entering the feed pipe 117 when not in use. Through the cooperation of the slide bar 108, the compression spring 107 and the sealing plate 109, the toy in the lower mold 105 can be lifted after molding, so that part of it can be moved out of the lower mold 105, making it convenient for the user to take it out. In subsequent actual use, the coolant in the groove 106 can cool and solidify the plastic in the lower mold 105.

[0028] Working principle: In use, the electric slide table 114 starts running first, directly driving the connecting plate 113 and the upper mold 116 to move up and down. The air compressor 115, connecting pipe 112, air outlet pipe 110, and support 111 are also driven by the force. When the upper mold 116 moves downward to a certain position, it can enter the lower mold 105 to complete the mold closing. Then, the sealing cover 118 is removed, and the raw material is poured into the feed pipe 117. The raw material can be injected between the upper mold 116 and the lower mold 105 for molding, and the raw material will be on the sealing plate 109. When the mold closing is completed, the slide rod 108, the compression spring 107, and the sealing plate 109 will feel pressure to facilitate subsequent molding. After the toy is ejected and the injection is completed, external coolant can enter the interior of the groove 106 through the liquid inlet pipe 201 for heat exchange and then be discharged through the liquid outlet pipe 103, which accelerates the molding of the workpiece in the mold. After molding, the upper mold 116 is reset by the electric slide table 114. At the same time as the reset, the compression spring 107 gradually loses its restraint. Then, the slide rod 108 and the sealing plate 109 use the elastic force of the compression spring 107 to eject the molded toy, exposing part of it to the outside. Then, through the cooperation of the air compressor 115, the air outlet pipe 110 and the connecting pipe 112, the molded toy is cooled by secondary air blowing. Through the cooperation of multiple components, it is easy for the user to take out the molded toy.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present 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 the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
