Description

Technical Field

[0001] The invention relates to the technical field of plastic mold forming, in particular to an extrusion-molding plastic mold based on recycled waste plastics. Background Art

[0002] Plastic molds are tools used in the plastics processing industry to complement plastic molding machines, giving plastic products complete shapes and precise dimensions. There are many types of plastics and processing methods, including extrusion plastic molds, which use the core inside the plastic mold to extrude the plastic product to give it a complete shape and precise dimensions.

[0003] Patent announcement number CN221872892U discloses a plastic mold extrusion stand, which relates to the field of mold production technology and includes a mounting table, a plurality of support blocks mounted on the upper surface of the mounting table, a top plate mounted on the upper ends of the plurality of support blocks, a cylinder mounted on the upper surface of the top plate, the output end of the cylinder passing through and extending to the bottom of the top plate, an extrusion plate mounted on the output end of the cylinder, mounting slots on both sides of the upper surface of the mounting table, a limiting mechanism disposed above the two mounting slots, a hydraulic rod mounted on the rear side of the lower surface of the mounting table, a fixed frame mounted on the output end of the hydraulic rod, and an opening on the rear side of the upper surface of the mounting table. This patent can limit the two sides of the plastic mold when it is extruded, and the position of the two limit frames is adjustable, which can adapt to plastic molds of different sizes. After the extrusion is completed, the extruded mold can be pushed out using a pushing mechanism, which facilitates continued operation and improves the automation effect of the equipment.

[0004] However, this device still has some shortcomings: the device realizes the limiting function of the plastic mold through the limit frame, but when limiting the lower mold, it is difficult to ensure that the lower mold and the upper mold process the same vertical plane, so it is easy to cause the upper mold and the lower mold to be offset in position during molding and extrusion, making it difficult for the two to fit completely for extrusion, which can easily cause the shape of the molding mold to change, thereby reducing the yield rate to a certain extent.

[0029] A Z-shaped plate 136 is fixedly installed on one side of the back of the cooling mechanism 134, a vertical rod 137 is fixedly installed on the top of one side of the back of the base 1, a mirror surface mechanism 138 is rotatably installed on the outer wall of the vertical rod 137 through a torsional spring, the mirror surface mechanism 138 effectively reduces the observation blind area when the upper die 8 extrudes the bottom die 4 in the rotating process, the outer wall of one end of the mirror surface mechanism 138 close to the cooling mechanism 134 is in contact with one end of the Z-shaped plate 136 close to the rotating rod 132, and the Z-shaped plate 136 limits the mirror surface mechanism 138.

The signal lamp 147 is convenient for the staff to judge whether the internal structure of the base 1 is normally operated through the reciprocating horizontal movement.

[0036] The vibration is generated through the reciprocating knocking of the double ball rods 142, so that the raw materials in the bottom die 4 can be uniformly filled in each corner inside the bottom die 4 before extrusion, and the finished product is ensured to be flawless. After the extrusion is completed, the adhesion between the mold and the bottom die 4 is reduced by the knocking vibration of the double ball rods 142 and the cold air of the cooling mechanism 134, so as to prevent the damage caused by too strong adhesion during demolding; the reciprocating horizontal movement of the signal lamp 147 prompts the staff to know whether the internal structure of the base 1 is normally operated at any time, so that the equipment can be found and repaired in time when the equipment fails, and the possibility of poor quality of the finished product mold caused by improper processing is further reduced.

[0038] According to the above embodiment, the vibration generated by the reciprocating knocking of the double ball bars 142 can make the raw material in the bottom die 4 uniformly fill the corners inside the bottom die 4 before extrusion, so as to ensure the finished product without defects. After the extrusion is completed, the knocking vibration of the double ball bars 142 and the cold air of the cooling mechanism 134 can reduce the adhesion between the mold and the bottom die 4, so as to prevent the mold from being damaged due to excessive adhesion during demolding. The reciprocating horizontal movement of the signal lamp 147 can prompt the workers to know whether the various structures inside the base 1 are in normal operation at all times. Thus, when the equipment fails, it can be found and repaired in time, and the possibility of poor quality of the finished product mold due to improper processing can be further reduced.

5. The extrusion molding plastic mold based on waste plastic recycling according to claim 4, characterized in that: A non-self-locking spiral groove begins on the outer wall of the top end of the rotating rod. The outer wall of the spiral groove of the rotating rod passes through and is movably installed inside the limiting ring. The top end of the rotating rod passes through the inside of the mounting mechanism. The cooling mechanism is used to reduce the temperature of the processing area. The outer wall of the bottom end of the round rod contacts the outer wall of the cam, and the outer wall of the top end of the round rod contacts the surface of the cooling mechanism.

6. The extrusion molding plastic mold based on waste plastic recycling according to claim 5, characterized in that: A Z-shaped plate is fixedly installed on one side of the back of the cooling mechanism, and a vertical rod is fixedly installed on the top of the back side of the base. The outer wall of the vertical rod is penetrated by a torsion spring and a mirror mechanism is rotatably installed. During the rotation of the mirror mechanism, the observation blind spot when the upper mold squeezes the bottom mold is effectively reduced. The outer wall of the mirror mechanism close to the cooling mechanism contacts the end of the Z-shaped plate close to the rotating rod, and the Z-shaped plate limits the mirror mechanism.

7. The extrusion molding plastic mold based on waste plastic recycling according to claim 6, characterized in that: The anti-adhesion device includes a transmission frame, the outer wall of which is observed and fixedly installed inside the round rod, and a double ball rod is slidably installed inside the transmission frame at one end away from the round rod through a spring, and several guide plates are equidistantly and fixedly installed at the center of the bottom of the inner wall of the base.

8. The extrusion molding plastic mold based on waste plastic recycling according to claim 7, characterized in that: The double ball rod relies on spring force to achieve vertical reset, the bottom of the bottom mold is located on the movement track of the top of the double ball rod, the top of the guide plate is designed as an arc surface, and the arc surface of the top of the guide plate is located on the movement track of the bottom of the double ball rod. The top of the double ball rod knocks the bottom mold to optimize the demoulding effect.

9. The extrusion molding plastic mold based on waste plastic recycling according to claim 8, characterized in that: An arc block is fixedly installed on the front of the transmission frame, and a sliding block is slidably installed inside one end of the front of the base through a spring. The sliding block is horizontally reset with the help of a spring, and a roller is rotatably installed inside one side of the back of the sliding block. The outer wall of the roller is in contact with the arc surface of the arc block. The roller is used to reduce the wear between the sliding block and the arc block. A signal light is fixedly installed inside one side of the front of the sliding block. The signal light makes reciprocating horizontal motion convenient for staff to judge whether the internal structure of the base is operating normally.
