[0002] Injection molds are devices that produce products with a certain shape after resin material is injected into a metal mold. During the injection molding process, if the raw material inside the mold is not evenly filled, resulting in a large number of air bubbles in the finished product and air encapsulation, the product needs to be remade. This requires the design of an injection mold. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides an injection mold to solve the problems existing in the background art.

[0004] This utility model provides the following technical solution: an injection mold, comprising an injection mold body, the injection mold body including two connecting members for connecting to an injection molding machine, a lower mold body and an upper mold body respectively disposed between the two connecting members, an injection tube disposed on the upper mold body, the lower mold body and the upper mold body being connected to the connecting members via a vibration assembly, the vibration assembly including a rubber plate, the rubber plate being fixedly installed at one end of the lower mold body and the upper mold body that is away from each other, the other end of the rubber plate being connected to the connecting members respectively, and a steel plate being installed inside the rubber plate. The upper mold body has a rubber plate and a steel plate at the top, with a through hole through which the injection tube passes. A vibration motor is fixedly installed on the outside of the lower mold body, and a switch for controlling the opening and closing of the vibration motor is provided on the outside of the lower mold body. A cooling component is provided inside the lower mold body. During the injection molding process, the vibration motor works, causing the lower mold body and the upper mold body to vibrate. This can vibrate and compact the raw material in the lower mold body during the injection molding process, avoiding the phenomenon of air bubbles and voids in the injection molded parts after injection molding. The rubber plate and steel plate can prevent the vibration from being transmitted to the injection molding machine.

[0005] Furthermore, a protective chamber is fixedly installed on the outer side of the lower mold body outside the vibration motor to wrap and protect the vibration motor.

[0006] Furthermore, the front of the protective chamber is designed to be open, and a lockable door is hinged to the front of the protective chamber. After opening the door on the protective chamber, the vibration motor can be inspected and repaired.

[0007] Furthermore, the lower mold body has a cooling chamber inside, and an inlet pipe connected to the cooling chamber is installed on the outside of the lower mold body. An outlet pipe connected to the cooling chamber is installed on the other side of the lower mold body. After injection molding is completed, water is injected into the cooling chamber through the inlet pipe to cool the lower mold body and the injection molded part. The heated water is discharged into the water supply equipment through the outlet pipe to cool the lower mold body and recover waste heat.

[0008] Furthermore, the liquid outlet pipe is located at the top of one side of the lower mold body, and the liquid inlet pipe is located at the bottom of the other side of the lower mold body, so as to better allow the water source to contact the inner wall of the cooling chamber for cooling.

[0009] Furthermore, the ends of the inlet pipe and outlet pipe away from the lower mold body are fixedly connected with corrugated pipes to prevent vibration from being transmitted to the water supply equipment and water use equipment.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. This utility model adopts this design, which allows the lower mold body and the upper mold body to be in a vibrating state during the injection molding process through the operation of the vibration motor. This can vibrate and compact the raw material in the lower mold body during the injection molding process, avoiding the phenomenon of air bubbles and voids in the injection molded parts after injection molding. The rubber plate and steel plate can prevent the vibration from being transmitted to the injection molding machine.

[0012] 2. This utility model adopts this design, which connects the water supply equipment and the water use equipment to the corrugated pipes on the liquid inlet pipe and the liquid outlet pipe respectively through pipes. After the injection molding is completed, the water supply equipment injects cooling water into the cooling chamber through the liquid inlet pipe to cool and lower the temperature of the lower mold body and the internal molded injection parts. The water source flows into the water use equipment through the liquid outlet pipe, which can recover and utilize the waste heat to assist in cooling the injection molded parts.

Detailed Implementation

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0019] Example 1: Refer to Figure 1-4 This utility model provides an injection mold, including an injection mold body 100. The injection mold body 100 includes two connectors 110 for connecting to an injection molding machine. A lower mold body 111 and an upper mold body 112 are respectively provided between the two connectors 110. An injection tube 113 is provided on the upper mold body 112. The lower mold body 111 and the upper mold body 112 are connected to the connectors 110 through a vibration assembly 200. The vibration assembly 200 includes a rubber plate 210, which is fixedly installed at one end of the lower mold body 111 and the upper mold body 112 that is far apart from each other. The other end of the rubber plate 210... The ends are connected to the connector 110 respectively. A steel plate 211 is installed inside the rubber plate 210. A through hole through which the injection tube 113 passes is opened at the center of the rubber plate 210 and the steel plate 211 at the top of the upper mold body 112. A vibration motor 212 is fixedly installed on the outside of the lower mold body 111. A switch for controlling the opening and closing of the vibration motor 212 is provided on the outside of the lower mold body 111. A cooling component 300 is provided inside the lower mold body 111. A protective chamber 213 is fixedly installed on the outside of the lower mold body 111 outside the vibration motor 212. The front of the protective chamber 213 is open. A lockable door is hinged to the front of the protective chamber 213.

[0020] The working principle of Embodiment 1 of this utility model is as follows: In use, the connector 110 is connected to the injection molding machine. After the lower mold body 111 and the upper mold body 112 are closed, the raw material is injected into the lower mold body 111 through the injection tube 113. At this time, the vibration motor 212 is driven to work. Through the work of the vibration motor 212, the lower mold body 111 and the upper mold body 112 are in a vibrating state. This can ensure that the raw material inside the lower mold body 111 is in a compact state during the injection molding process. The rubber plate 210 buffers the vibration of the lower mold body 111 and the upper mold body 112, preventing the vibration from being transmitted to the injection molding machine.

[0021] Example 2:

[0022] The difference between Embodiment 2 and Embodiment 1 is that: a cooling chamber 310 is provided inside the lower mold body 111; an inlet pipe 311 connected to the cooling chamber 310 is installed on the outer side of the lower mold body 111; and an outlet pipe 312 connected to the cooling chamber 310 is installed on the other side of the lower mold body 111. The outlet pipe 312 is located at the top of one side of the lower mold body 111, and the inlet pipe 311 is located at the bottom of the other side of the lower mold body 111. The inlet pipe 311 and the outlet pipe 312 are far from the lower mold body 111. The end is fixedly connected with a corrugated pipe 313, and the water supply equipment and the water use equipment are connected to the corrugated pipe 313 on the liquid inlet pipe 311 and the liquid outlet pipe 312 respectively through pipes. After the injection molding is completed, the water supply equipment injects cooling water into the cooling chamber 310 through the liquid inlet pipe 311 to cool down the lower mold body 111 and the internal molded injection parts. The water source flows into the water use equipment through the liquid outlet pipe 312, which can recover and utilize the waste heat to help cool down the injection molded parts.
