Description

Technical Field

[0001] The present invention relates to the technical field of molds, and specifically to a dual-material slider mold. Background Art

[0002] Molds are called the mother of industry. More ingenious mold structure designs will greatly improve the structure, quality and production efficiency of products. Therefore, higher requirements are imposed on mold designers. The development and design of dual-material molds are for meeting the requirements of customers to use different materials, hardnesses and colors at different positions of the same product. It can achieve different positions in the same product and make different materials, colors and hardnesses in the same mold as required.

[0003] During the use of existing dual-material slider molds, it is difficult to apply micro-vibrations to the dual-material joint surface and match it with the molten state of the material, which reduces molecular diffusion. At the same time, it is difficult to improve the melt wettability of the dual-material interface, and the practicability is relatively single. During the use of the existing technology, it is difficult to compensate for the gap between the slider and the mold, which reduces the mold closing accuracy, and thus it is difficult to prevent melt leakage and air gap formation. In addition: during the use of existing dual-material slider molds, it is difficult to configure temperature control regions for the injection molding of each material, and thus it is difficult to solve the thermodynamic contradiction of co-injection of multiple materials, increasing product defects. During the flow process of the melt, stratification is easily formed due to uneven flow velocity. The existing technology is difficult to reduce the local differences in melt temperature and viscosity, resulting in a relatively uneven melt state at the gate, increasing the possibility of local blockage or coverage of the test piece. Finally: during the use of existing dual-material slider molds, it is difficult to perform elastic detection on products completed by one injection molding, and thus it is difficult to provide a basic performance anchor point for two-layer injection molding, increasing the product defect rate and shortening the service life of the product.

The mounting plates 33 facilitate the installation of the electromagnetic slots 34.

[0023] An electromagnetic slot 34 is provided at the right rear end of the mounting plate 33. The right end of the electromagnetic slot 34 is slidably connected to the inner tooth plate of the first gear and rack member 35. Six groups of connecting seats 36 are fixedly connected to the inner bottom of the slider body 31. Fixed rods 37 are fixedly connected to the upper left ends of three groups of connecting seats 36 inside the slider body 31. The connecting seats 36 facilitate the installation and fixation of the fixed rods 37.

[0024] A first knocking block 38 is rotatably connected to the outer wall of the fixed rod 37. The right end of the inner gear of the first gear and rack member 35 is fixedly connected to a second knocking block 39 through a gear rod. Electromagnetic blocks 310 are fixedly connected to the lower right ends of the first knocking block 38 and the second knocking block 39, and the electromagnetic blocks 310 are electrically connected to an external current output device. The second knocking block 39 facilitates the installation and fixation of the electromagnetic blocks 310.

[0025] The electromagnetic slot 34 is composed of a chute provided at the right rear end of the mounting plate 33 and six groups of electromagnetic blocks fixedly connected in the chute, and the electromagnetic blocks are electrically connected to an external current output device. The electromagnetic blocks in the electromagnetic slot 34 are magnetically adsorbed to the inner tooth plate of the first gear and rack member 35.

[0026] The sliding groove in the electromagnetic groove 34 is slidably connected to the internal tooth plate of the first gear tooth plate member 35. The left end of the internal gear of the first gear tooth plate member 35 is rotatably connected to the right front end of the mounting plate 33.

[0027] The working principle of a dual-material slider mold based on Embodiment 1 is as follows: First, when using this device, first place this device in the working area, and then connect the device to an external power source to provide the power required for the operation of this device. Second, when using the dual-material slider mold, the operator connects the material conveying member to the pouring tube 4, and then uses external equipment to perform mold closing and injection molding on the lower mold 1 and the upper mold 2. After the injection molding of the first mold is completed, the external machine table bottom plate drives the lower mold 1 to rotate 180 degrees, and then closes the mold again for the second injection molding, which is perfectly welded to the product of the first injection molding to complete the dual-material injection molding. Third, after the lower mold 1 and the upper mold 2 are closed, six electromagnetic blocks in the electromagnetic groove 34 are driven by an external current output device to work step by step, causing the internal tooth plate of the first gear tooth plate member 35 to move up and down under the influence of the magnetic adsorption of the six electromagnetic blocks in the electromagnetic groove 34. The internal tooth plate of the first gear tooth plate member 35 drives the internal gear of the first gear tooth plate member 35 to rotate. The gear rod at the right end of the internal gear of the first gear tooth plate member 35 drives the second knocking block 39 to knock on the bottom of the slider body 31 through rotation. When it is necessary to change the knocking weight, the electromagnetic block 310 is driven by an external current output device to work. Through the magnetic adsorption of the electromagnetic block 310, the second knocking block 39 is magnetically adsorbed to the first knocking block 38 and the three first knocking blocks 38 are magnetically adsorbed to achieve the adjustment of the knocking weight. Then, the second knocking block 39 drives the first knocking block 38 to knock on the bottom of the slider body 31, thereby applying a micro-vibration to the dual-material joint surface and matching the vibration with the molten state of the material to enhance molecular diffusion and improve the melt wettability of the dual-material interface at the same time.

[0028] Embodiment 2:

[0029] Please refer to Figure 5 , for a dual-material slider mold of the present invention, compared with Embodiment 1, this embodiment further includes: a compensation mechanism 32. The compensation mechanism 32 includes a cemented carbide coating 321. The bottom of the slider body 31 is plasma-sprayed with a cemented carbide coating 321, and the cemented carbide coating 321 is convenient for improving the hardness of the contact surface with the upper mold 2.

[0030] The bottom of the cemented carbide coating 321 is adhesively connected with a flexible metal mesh 322. The bottom of the flexible metal mesh 322 is electrostatically sprayed with a self-lubricating PTFE coating 323. The self-lubricating PTFE coating 323 is convenient for reducing the friction coefficient of the contact surface and reducing the sliding resistance of the slider body 31.

[0031] A self-lubricating PTFE coating 323 is adhesively connected to the bottom of a shape memory alloy 324, and a composite shape memory polymer layer 325 is adhesively connected to the bottom of the shape memory alloy 324.

[0032] In this embodiment: After the lower mold 1 and the upper mold 2 are closed, the hardness of the contact surface of the upper mold 2 is increased by the cemented carbide coating 321 to resist the wear caused by the repeated extrusion of the shape memory alloy 324, and a metallurgical bond is formed with the upper mold 2 to prevent the subsequent layer from falling off. Then, the shear stress generated during the deformation of the shape memory alloy 324 is absorbed by the flexible metal mesh 322 to avoid cracking. At the same time, a small amount of lubricating medium is stored through the mesh structure to assist in reducing friction. The self-lubricating PTFE coating 323 is used to reduce the friction coefficient of the contact surface, reduce the sliding resistance of the slider body 31, fill the pores of the flexible metal mesh 322, form a continuous lubricating film, and prevent the melt from penetrating into the composite layer gap. Then, during injection molding, the melting temperature of the melt is transmitted to the shape memory alloy 324, causing its temperature to rise and undergo a phase change, generating deformation, and changing the shape and size of the shape memory alloy 324 through installation and disassembly, so that the amount of deformation matches the change in the gap of the slider body 31 caused by thermal expansion, thereby compensating for the gap, improving the mold closing accuracy, preventing melt leakage and air gap formation, and the composite shape memory polymer layer 325 softens and expands prior to the shape memory alloy 324 at the initial stage of melt injection to fill the micro gaps. The flexibility of the composite shape memory polymer layer 325 can buffer the melt impact and protect the shape memory alloy 324 from instantaneous high-pressure damage.

Through this control switch 510, the heating wire inside the heating element 51 is driven to work. The heating wire inside the heating element 51 raises the temperature of the melt in the pouring pipe 4 through heat transfer.
