[0021] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0022] Some embodiments of the present invention are described below with reference to the accompanying drawings.

[0023] Example 1:

[0024] Combine Figure 1-3 As shown, this embodiment provides an easy-to-operate injection mold, including: a main body mechanism 100 and an ejection mechanism 200.

[0025] Among them, the main mechanism 100 includes a lower mold 110, a plurality of guide tubes 120 fixed to the top of the lower mold 110, an upper mold 130 slidably sleeved on the guide tubes 120, an ejector 140 arranged at the bottom end of the lower mold 110 and extending through the lower mold 110, a transmission member 150 fixed on both sides of the ejector 140 and extending into the guide tubes 120, a U-shaped frame 160 symmetrically fixed to the bottom end of the lower mold 110, and an elastic member 170 symmetrically installed on the U-shaped frame 160 and fixedly connected to the ejector 140.

[0026] The lower mold 110 and the upper mold 130 cooperate with each other to form a molding space for the product, which is convenient for injection molding of subsequent products. The guide tube 120 is used to guide the movement of the upper mold 130 to ensure the accuracy when the upper mold 130 and the lower mold 110 are closed. There are circular holes 131 at the four corners of the upper mold 130. The guide tube 120 extends through the circular hole 131. A boss 132 is fixed on the inner wall of the circular hole 131. The boss 132 is embedded in the inner cavity of the guide tube 120, so that when the upper mold 130 moves, it can drive the boss 132 to move synchronously, which is convenient for the subsequent boss 132 to drive the transmission part 150 to move.

[0027] The ejector 140 is used to eject the product from the lower mold 110, and includes a base plate 141 arranged below the lower mold 110 and multiple ejector rods 142 fixed on the base plate 141 and extending through the lower mold 110. The base plate 141 is used to install the ejector rods 142 and drive the multiple ejector rods 142 to move synchronously. The ejector rods 142 can eject the product from the inside of the mold to the outside, making it convenient for workers to take it.

[0028] The transmission member 150 is used to drive the ejector 140 to move, and includes support plates 151 fixed on both sides of the base plate 141 and transmission rods 152 symmetrically fixed on the support plates 151 and extending into the guide tube 120. The support plates 151 are used to install the transmission rods 152. At the same time, the transmission rods 152 extend into the guide tube 120. When the upper mold 130 moves downward, the boss 132 and the lower mold 110 move downward synchronously. When the boss 132 contacts the top of the transmission rod 152, it drives the transmission rod 152 to move downward. The transmission rod 152 moves downward, and the ejector 140 moves downward synchronously through the support plates 151, thereby resetting the ejector 140.

[0029] The U-shaped rod is used to limit the ejection part 140 and to install the elastic part 170. The elastic part 170 is used to provide an upward force for the ejection part 140 to facilitate the ejection of the product by the ejection part 140. The elastic part 170 includes a shell 171 fixed to the U-shaped frame 160, a T-shaped rod 172 with one end arranged in the inner cavity of the shell 171 and the other end extending out of the shell 171 and fixedly connected to the ejection part 140, and a spring 173 connecting the end of the T-shaped rod 172 to the inner bottom wall of the shell 171. The shell 171 limits the movement of the T-shaped rod 172. The T-shaped rod 172 is fixedly connected to the ejection part 140 to facilitate the movement of the ejection part 140. The spring 173 provides elastic force to ensure that the ejection part 140 is ejected outward.

[0030] The ejection mechanism 200 is used to push the product out from the inside of the mold, and includes a side plate 210 fixed to one side of the lower mold 110, an electric telescopic rod 220 installed on the side plate 210, a rubber push plate 230 fixed to the end of the electric telescopic rod 220, and a trigger member 240 fixed to the side plate 210.

[0031] The side panel 210 is used to install the electric telescopic rod 220 to ensure the stability of the electric telescopic rod 220. The electric telescopic rod 220 is used to install the rubber push plate 230 and drive the rubber push plate 230 to move, so as to facilitate the ejected product to be pushed out of the mold, so that the workers can directly take it.

[0032] The trigger member 240 is used to trigger the electric telescopic rod 220, including a bracket 241 fixed on the side panel 210 and a touch sensor 242 installed on the bracket 241. The support rod is used to install the touch sensor 242, and the touch sensor 242 is used to detect the touch signal. When the upper mold 130 moves upward and comes into contact with the touch sensor 242, the touch sensor 242 activates the electric telescopic rod 220 to push the product to the outside of the mold.

[0033] The working principle and use process of the utility model are as follows: during injection molding, the upper mold 130 is pressed down, driving the convex column 132 in the guide tube 120 to move downward synchronously. When the upper mold 130 is in close contact with the lower mold 110, the guide column drives the transmission member 150 to move downward, and the transmission member 150 moves downward to drive the ejector 140 to move downward, so that the ejector 140 retracts to its original position, and the injection molding operation can begin. When the product is injected and cooled, the upper mold 130 moves upward, driving the convex column 132 to move upward. At this time, the transmission member 150 moves downward to drive the ejector 140 to move downward, so that the ejector 140 retracts to its original position, and the injection molding operation can begin. Part 150 loses its limit, and under the action of spring 173, it drives the T-bar 172 to move upward. The upward movement of the T-bar 172 drives the ejector 140 to move upward, ejecting the molded product from the lower mold 110. At the same time, when the upper mold 130 contacts the touch sensor 242, the touch sensor 242 detects the touch signal and starts the electric telescopic rod 220. The electric telescopic rod 220 starts to drive the rubber push plate 230 to move, pushing the ejected product to the outside of the mold, making it easier for workers to take it.

[0034] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
