Description

Technical Field

[0001] This utility model relates to the field of plastic mop technology, specifically to a mold for forming the handle of a plastic mop. Background Technology

[0002] Plastic mops are floor cleaning tools made of plastic. They are lightweight, durable, and corrosion-resistant. A mop consists of two parts: the head and the handle. During manufacturing, a molding die is used. The molding die can process the raw materials into a specific shape through injection molding. The mold cavity is consistent with the product, resulting in high production efficiency, and each product has the same standard.

[0003] Currently, there are still some shortcomings in molding molds, such as plastic products easily sticking to the inside of the mold, making them inconvenient to remove.

[0004] To overcome the problem of inconvenient removal of plastic parts from molds, a prior art Chinese patent (publication number: CN216941466U) discloses a plastic product molding mold. It uses the mutual limiting and locking between the limiting rod and the limiting hole to make the moving mold and the fixed mold accurately positioned. The limiting rod can move relative to each other to clamp the molded plastic parts. As the lifting component moves, it is convenient to remove the molded plastic parts from the mold, avoiding manual removal by the operator. This improves the removal efficiency and prevents the residual heat of the mold from causing damage to the operator during manual operation.

[0005] However, the molding mold currently in use still has certain shortcomings. The document mentioned above uses a clamping method and lifting components to remove the molded product, which can prevent operators from being burned and improve material handling efficiency. However, the clamping method uses threads, and it is difficult to control the clamping force precisely, which may damage the product surface. Therefore, the existing structure needs to be improved. Utility Model Content

[0006] The purpose of this utility model is to provide a mold for forming the handle of a plastic mop, so as to solve the problem mentioned in the background art that the mold is inconvenient for material handling and affects production efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a mold for forming the handle of a plastic mop, comprising a base, a lower mold connected to the top of the base, an upper frame connected to the back of the base, an upper mold connected to the bottom of the upper frame via a hydraulic rod, and injection ports symmetrically connected to the top of the upper mold.

[0008] The lower mold has three sets of arc-shaped blocks connected to its inner side. Guide blocks are symmetrically fixed at the bottom of the arc-shaped blocks. The guide blocks slide on the inner side of the lower mold. The lower mold also has a sliding groove and a lifting mechanism for easy demolding.

[0009] Furthermore, the lifting mechanism includes a sliding rod slidably connected inside the sliding groove, and an electric push rod is also installed inside the sliding groove. The output end of the electric push rod is connected to the right end of the sliding rod. A rotating groove is opened on the side of the sliding groove, and an external block is slidably connected inside the rotating groove. An arc-shaped block is connected to the top of the external block.

[0010] Furthermore, the outer block is symmetrically fixed with limit blocks on its side, and a reciprocating column is rotatably connected inside the outer block, with a gear connected to the bottom end of the reciprocating column.

[0011] Furthermore, the gear rotates inside the rotating groove via a bearing, and a toothed plate is meshed with the side of the gear. A sliding rod is connected to the side of the toothed plate away from the gear, and the toothed plate slides inside the sliding groove. A pressing block is slidably connected to the groove on the side of the reciprocating column, and the pressing block is fixed inside the outer block.

[0012] Furthermore, a T-shaped block is fixed to the top of the outer block, and an assembly mechanism for replacing the arc-shaped block is provided on the top of the outer block. The assembly mechanism includes a positioning ball that slides telescopically inside the T-shaped block.

[0013] Furthermore, a spring connects the positioning ball and the T-shaped block, and a T-shaped groove is provided at the bottom of the arc-shaped block. A positioning groove is provided on the side of the T-shaped groove, and the positioning groove and the positioning ball are positioned together, while the T-shaped groove and the T-shaped block are slidably connected.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The plastic mop handle forming mold has an electric push rod that pushes the sliding rod to move along the sliding groove during material feeding. This can drive three sets of toothed plates to mesh and rotate the gears. Then, through the reciprocating column, the extrusion block is squeezed, causing the outer block and the limit block to move upward. This pushes the arc block and the guide block to slide along the base, pushing the material out of the lower mold and improving material feeding efficiency.

[0016] 2. A guide block is provided to guide the arc-shaped block, ensuring that it does not tilt when pushing the plastic part to pick up the material, thus guaranteeing the stability of the arc-shaped block's operation.

[0017] 3. It is equipped with a reciprocating column. When the reciprocating column rotates, it can squeeze the extrusion block and quickly push the arc block upward, which improves the efficiency of mold material handling.

[0018] 4. Equipped with a sliding rod, which can simultaneously drive three sets of toothed plates to move, allowing the three sets of arc-shaped blocks to move upward synchronously to pick up materials, further improving the efficiency of material picking in the mold.

[0019] 5. Equipped with positioning balls, the T-block can be directly inserted into the T-slot for positioning, facilitating the disassembly and replacement of the arc block and simplifying the later maintenance of mold components. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1, such as Figures 1-6The present invention provides the following technical solution to address the problem of inconvenient material removal from molds, which affects production efficiency: A lifting mechanism is disclosed, comprising a base 1, a lower mold 2 connected to the top of the base 1, an upper frame 3 connected to the back of the base 1, an upper mold 4 connected to the bottom of the upper frame 3 via a hydraulic rod, and injection ports 5 symmetrically connected to the top of the upper mold 4. Three sets of arc-shaped blocks 101 are connected to the inner side of the lower mold 2, and guide blocks 102 are symmetrically fixed to the bottom of the arc-shaped blocks 101. The guide blocks 102 slide within the lower mold 2. A sliding groove 103 is also provided inside the lower mold 2. A lifting mechanism for easy demolding is provided inside the lower mold 2. The lifting mechanism includes a sliding rod 104 slidably connected inside the sliding groove 103, and an electric push rod is also installed inside the sliding groove 103. The electric push rod... The outlet is connected to the right end of the sliding rod 104. A rotating groove 105 is provided on the side of the sliding groove 103. An outer block 106 is slidably connected inside the rotating groove 105. An arc-shaped block 101 is connected to the top of the outer block 106. Limiting blocks 107 are symmetrically fixed on the side of the outer block 106. A reciprocating column 108 is rotatably connected inside the outer block 106. A gear 109 is connected to the bottom of the reciprocating column 108. The gear 109 rotates inside the rotating groove 105 through a bearing. A toothed plate 110 is meshed with the side of the gear 109. A sliding rod 104 is connected to the side of the toothed plate 110 away from the gear 109, and the toothed plate 110 slides inside the sliding groove 103. A pressing block 111 is slidably connected to the groove on the side of the reciprocating column 108. The pressing block 111 is fixed inside the outer block 106.

[0030] When the molding die is in use, the upper mold 4 and the lower mold 2 are merged by the hydraulic drive of the upper frame 3. Then, the material is injected into the cavity of the upper mold 4 and the lower mold 2 through the injection port 5. After cooling, a plastic grip is formed. When unloading the material, the electric push rod is activated to push the sliding rod 104 to move. When the sliding rod 104 moves, it can slide through the sliding groove 103. When the sliding rod 104 slides, it can push the three sets of toothed plates 110 to slide. When the three sets of toothed plates 110 slide, they can drive the gears 109 to mesh and rotate. When the gears 109 mesh and rotate, they can rotate inside the rotating groove 105 through the bearing. When the gears 109 rotate, they can drive the reciprocating column 108 to rotate. When the column 108 rotates, the grooves on its side can compress the extrusion block 111. When the extrusion block 111 is compressed, it can drive the outer block 106 to move upward. When the outer block 106 moves upward, it can drive the limiting block 107 to move. Both the outer block 106 and the limiting block 107 can slide upward through the rotating groove 105. When the outer block 106 slides upward, it can push the arc block 101 to move upward. When the arc block 101 moves upward, it can drive the two guide blocks 102 to move. When the two guide blocks 102 move, they can slide through the base 1. The arc block 101 slides to the bottom of the molding material and pushes it upward. After the material is pushed out of the upper mold 4, it is convenient for workers to take it away, which improves the efficiency of mold material removal.

[0031] Example 2, as follows Figure 7 The present invention provides the following technical solution to address the problem of difficulty in replacing the arc-shaped block 101 of the mold after damage. Based on Embodiment 1, an assembly mechanism is disclosed: a T-shaped block 201 is fixed to the top of the outer block 106, and an assembly mechanism for replacing the arc-shaped block 101 is provided on the top of the outer block 106. The assembly mechanism includes a positioning ball 202 that slides telescopically inside the T-shaped block 201. A spring connects the positioning ball 202 and the T-shaped block 201. A T-shaped groove 203 is provided at the bottom of the arc-shaped block 101, and a positioning groove 204 is provided on the side of the T-shaped groove 203. The positioning groove 204 and the positioning ball 202 are positioned together, and the T-shaped groove 203 and the T-shaped block 201 are slidably connected.

[0032] When the arc block 101 of the mold becomes worn, slightly deformed, or skewed after prolonged use, it needs to be replaced. The arc block 101 can be raised to a certain height. After the arc block 101 is raised to the designated position, it can be pushed to the side. When the arc block 101 is pushed, it can drive the T-slot 203 to move. When the T-slot 203 moves, it can slide through the T-block 201. The T-slot 203 can also drive the inclined surface of the positioning groove 204 to press the positioning ball 202. After being pressed, the positioning ball 202 can slide to the bottom through the T-block 201. When the positioning ball 202 slides out of the positioning groove 204, the T-slot 203 can slide out of the side of the T-block 201. At this time, the arc block 101 and the outer block 106 can be separated and disassembled. After disassembly, a new arc block 101 can be replaced, which facilitates the later maintenance of mold parts.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
