Description

Technical Field

[0001] The utility model relates to the technical field of plastic molds, in particular to a plastic mold with good exhaust effect. Background Art

[0002] Plastic molds are important tools in the production process of plastic products. They form plastic raw materials into products of desired shapes and sizes through processes such as compression molding, extrusion molding, injection molding, blow molding and low-foaming molding. Plastic molds play an important role in the plastic industry and are widely used in daily life, industrial production, automobiles, electronics and other fields. During the product injection molding process, a certain amount of gas will be generated when the mold and equipment are rubbed, heated and the plastic is melted. In order to solve the problem of gas generated by plastic molds during the injection molding process, exhaust grooves or exhaust holes are opened on the mold parting surface to remove the air in the mold cavity and the gas generated by the plastic;

[0003] Traditional plastic molds mainly vent air through exhaust grooves or exhaust holes. Due to long-term use of the mold or improper process, the exhaust holes or exhaust grooves may be blocked by plastic residues, bubbles or foreign matter, affecting the exhaust effect.

[0004] In order to solve the above problems, the present application proposes a plastic mold with good exhaust effect. Utility Model Content

[0005] Based on the technical problems existing in the background technology, the utility model proposes a plastic mold with good exhaust effect.

[0006] The utility model provides a plastic mold with good exhaust effect, comprising a mold body and a support;

[0007] A frame is installed on the support, a rod-type elastic member is installed in the frame, the mold body is sleeved on the rod-type elastic member, and a driving member for driving the mold body to reciprocate along the rod-type elastic member is installed on the support;

[0008] An exhaust groove is provided in the mold body, and an air outlet member connected to the exhaust groove is connected to the mold body. An airbag member located on the reciprocating movement path of the mold body is installed on the inner wall of the frame, and the airbag member is connected to the air outlet member.

[0009] Preferably, the rod-type elastic member includes two connecting rods, and the two connecting rods are installed in the frame. Blocks are installed on both sides of the bottom of the mold body. The two blocks are slidably sleeved on the two connecting rods respectively. A spring is sleeved on the connecting rod, and the two ends of the spring are respectively connected to the block and the inner wall of the frame.

[0010] Preferably, the driving member comprises a servo motor, the servo motor is mounted on a support, an output end of the servo motor is connected to an eccentrically arranged disc, and the disc abuts against one end of the mold body.

[0011] Preferably, the air outlet member includes an air outlet pipe, an assembly block and an axial flow fan, the air outlet pipe is installed on the side of the mold body and communicates with the exhaust groove, the assembly block is installed in the air outlet pipe, and the axial flow fan is rotatably connected to the side of the assembly block.

[0012] Preferably, the airbag component comprises an airbag ball, which is mounted on the inner wall of the frame and abuts against one end of the mold body away from the disc, and the airbag ball is connected to an air supply pipe, and one end of the air supply pipe away from the airbag ball is connected to the air outlet component.

[0013] The above technical solution of the utility model has the following beneficial technical effects:

[0014] By providing the rod-type elastic member and the driving member, the plastic mold can be driven by the driving member to move the mold body back and forth along the direction of the rod-type elastic member during use, which can cause the mold body to shake. This structure drives the mold body to move back and forth along the direction of the rod-type elastic member, causing the mold body to shake, which helps to promote the flow of gas in the mold body, thereby improving the exhaust effect. At the same time, the shaking can effectively prevent plastic residues, bubbles or foreign matter from being retained in the mold body, thereby improving the quality of plastic products.

[0015] By setting the air outlet piece and the airbag piece, the exhaust groove in the mold body can be discharged through the air outlet piece when exhausting. When the mold body moves back and forth, it can repeatedly squeeze the airbag piece to guide the gas into the air outlet piece, thereby accelerating the speed of gas discharge from the exhaust groove and playing an auxiliary role. This structure utilizes the reciprocating movement of the mold body to repeatedly squeeze the airbag piece to guide the gas into the air outlet piece, thereby accelerating the speed of gas discharge from the exhaust groove.

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0020] like Figure 1 and Figure 2 As shown, the utility model provides a plastic mold with good exhaust effect, comprising a mold body 1 and a support 2;

[0021] In this embodiment, a frame 3 is mounted on the support 2, a rod-type elastic member 4 is mounted in the frame 3, and the mold body 1 is sleeved on the rod-type elastic member 4. The rod-type elastic member 4 includes two connecting rods 41, and the two connecting rods 41 are mounted in the frame 3. Blocks 8 are mounted on both sides of the bottom of the mold body 1, and the two blocks 8 are respectively slidably sleeved on the two connecting rods 41. A spring 42 is sleeved on the connecting rod 41, and the two ends of the spring 42 are respectively connected to the block 8 and the inner wall of the frame 3.

[0022] In this embodiment, a driving member 5 is mounted on the support 2 for driving the mold body 1 to reciprocate along the rod-type elastic member 4. The driving member 5 includes a servo motor 51, which is mounted on the support 2. An eccentrically arranged disc 52 is connected to the output end of the servo motor 51, and the disc 52 abuts against one end of the mold body 1.

[0023] It should be noted that in order to accelerate the discharge of gas and prevent foreign matter from being retained, during the use of the plastic mold, the servo motor 51 can drive the disc 52 to push the sleeve blocks 8 on both sides of the mold body 1 to move along the connecting rod 41. Under the action of the spring 42, the mold body 1 can be reciprocated. The mold body 1 can be shaken. This structure drives the mold body 1 to move back and forth along the direction of the rod-type elastic member 4, causing the mold body 1 to shake, which helps to promote the flow of gas in the mold body 1, thereby improving the exhaust effect. At the same time, shaking can effectively prevent plastic residues, bubbles or foreign matter from being retained in the mold body 1, thereby improving the quality of plastic products.

[0024] In this embodiment, an exhaust groove is provided in the mold body 1, and an air outlet member 6 connected to the exhaust groove is connected to the mold body 1. The air outlet member 6 includes an air outlet pipe 61, an assembly block 62 and an axial flow fan 63. The air outlet pipe 61 is installed on the side of the mold body 1 and is connected to the exhaust groove. The assembly block 62 is installed in the air outlet pipe 61, and the axial flow fan 63 is rotatably connected to the side of the assembly block 62.

[0025] In a further embodiment, an airbag component 7 located on the reciprocating path of the mold body 1 is installed on the inner wall of the frame 3, and the airbag component 7 is connected to the air outlet component 6. The airbag component 7 includes an airbag ball 71, which is installed on the inner wall of the frame 3 and abuts against an end of the mold body 1 away from the disc 52. An air supply pipe 72 is connected to the airbag ball 71, and an end of the air supply pipe 72 away from the airbag ball 71 is connected to the air outlet component 6.

[0026] It should be noted that: in order to further accelerate the discharge of gas, the exhaust groove in the mold body 1 can be discharged through the outlet pipe 61 when exhausting. When the mold body 1 moves back and forth, it can repeatedly squeeze the airbag ball 71, and guide the gas along the air supply pipe 72 to the outlet pipe 61, blowing the axial flow fan 63 to rotate on the assembly block 62, thereby accelerating the speed of gas discharge from the exhaust groove, playing an auxiliary role. This structure utilizes the reciprocating movement of the mold body 1 to repeatedly squeeze the airbag part 7 and guide the gas to the outlet part 6, thereby accelerating the speed of gas discharge from the exhaust groove.
