Description

Technical Field

[0001] This utility model relates to the field of mold cooling water channel technology, and in particular to a cooling water channel structure for a precision mold. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain desired products through injection molding, blow molding, extrusion, die casting, forging, smelting, stamping, and other methods. In short, molds are tools used to create shaped objects. These tools are composed of various parts, and different molds are composed of different parts. They mainly achieve the processing of the shape of the object by changing the physical state of the material being molded. They are often referred to as the "mother of industry." The cooling water channel of a mold refers to the water channel system opened in the mold. Through the continuous circulation of coolant, the heat inside the mold is carried away, thereby cooling the mold. The cooling water channel system is usually connected to an external water source to form one or more water loops.

[0003] The cooling channel structure of common precision molds is relatively simple, usually located inside the mold. After long-term use, scale will form inside the channel, which will seriously affect the cooling effect of the mold. The scale cleaning process is very cumbersome, and some channels cannot even be cleaned, which will lead to a reduction in the efficiency of mold use. Therefore, we propose a cooling channel structure for precision molds. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. The cooling water channel structure of common precision molds is relatively simple, usually located inside the mold. After prolonged use, scale will form inside the water channel, which will seriously affect the cooling effect of the mold. The cleaning process for scale is very cumbersome, and some water channels cannot even be cleaned, which will lead to a reduction in the efficiency of mold use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cooling water channel structure for a precision mold includes a mold body, wherein a coil is provided inside the mold body;

[0007] The mold body has an annular groove inside, and an auxiliary component is installed at the bottom of the annular groove. A heat-conducting layer is bonded inside the annular groove and on the inner side of the coil. The left and right sides of the mold body have built-in grooves near the top, and a fixing component is installed inside the built-in grooves.

[0008] The coil is installed inside the annular groove. A water inlet pipe is installed at the end of the coil near the bottom of the annular groove, and a water outlet pipe is installed at the end of the coil away from the water inlet pipe.

[0009] As a preferred embodiment of this utility model, a wiring groove is provided on the front of the mold body and around the periphery where the water inlet pipe and water outlet pipe are located.

[0010] The technical advantages of adopting the above-mentioned further solution are: the cable tray facilitates the installation of water inlet and outlet pipes, and at the same time, the cable tray can limit the coil through the water inlet and outlet pipes, preventing it from rotating inside the annular groove during use, thus improving the stability of use.

[0011] As a preferred embodiment of this utility model, a forming groove is provided inside the mold body and on the inner side of the annular groove.

[0012] As a preferred embodiment of this utility model, the auxiliary component includes a base plate, which is a circular stainless steel structure, and a first spring is fixedly connected between the bottom of the base plate and the annular groove.

[0013] The technical effect of adopting the above-mentioned further solution is that the first spring can push the base plate upward, thereby causing the base plate to push the coil above it out of the annular groove, which facilitates the disassembly and replacement of the coil and improves the ease of use.

[0014] As a preferred embodiment of this utility model, the thermally conductive layer is made of thermally conductive graphite sheet with a thickness of 0.5 cm.

[0015] The technical effect of adopting the above-mentioned further solution is that the thermally conductive graphite sheet has excellent thermal conductivity, chemical stability and outstanding mechanical strength. The heat exchange of the coil can be more uniform through the thermally conductive layer, thereby improving the heat exchange and cooling effect.

[0016] As a preferred embodiment of this utility model, the fixing component includes a push plate, which is slidably connected to the built-in groove. An adjusting rod is rotatably connected to the outer side of the push plate extending to the periphery of the mold body. A knob is welded to the end of the adjusting rod away from the push plate. Limiting rods are symmetrically welded to the outer side of the push plate near the front and back. The limiting rods are slidably connected to the mold body. A second spring is fixedly connected between the end of the limiting rod away from the push plate and the mold body.

[0017] The technical effect of adopting the above-mentioned further solution is that the second spring can push the limiting rod, causing the limiting rod to move the push plate inward to the top of the coil, thereby fixing the coil and preventing the coil from falling out of the annular groove during use. The limiting rod can limit the moving push plate to prevent it from deviating and improve the stability of use.

[0018] As a preferred embodiment of this utility model, the push plate is made of semi-circular stainless steel, and a protective pad is adhered to the inner side where it contacts the heat-conducting layer.

[0019] The technical effects of adopting the above-mentioned further solutions are: stainless steel has strong corrosion resistance, which can improve the service life of the push plate; and the protective pad can prevent the push plate from directly contacting the heat-conducting layer, thus improving the protection effect of the heat-conducting layer.

[0020] As a preferred embodiment of this utility model, the outer periphery of the knob has protrusions extending outwards near the front and back.

[0021] The technical effect of adopting the above-mentioned further solution is that by pulling the knob outward to disengage it from the mold body and rotating it 90 degrees, the protrusion can be locked on the outer periphery of the mold body, thereby achieving the purpose of pulling the push plate into the built-in groove and fixing it, preventing the push plate from obstructing the removal of the coil and improving the ease of use.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] In this invention, by designing the mold body and the coil, pulling the knob outward and rotating it 90 degrees allows the knob to pull the push plate into the built-in groove via the adjusting rod, releasing the coil from its fixation. At this time, the second spring pushes the base plate upward, allowing the base plate to push the coil out of the annular groove for cleaning and replacement. Compared with traditional mold water channels, this allows for quick replacement, greatly improving ease of use and effectively increasing the efficiency of the mold body.

[0033] Example 1:

[0034] like Figure 1-4 As shown, this utility model provides a technical solution: a cooling water channel structure for a precision mold, including as follows Figure 1As shown, the cooling water channel structure of the precision mold in this embodiment includes a mold body 1, a coil 2 inside the mold body 1, an annular groove 101 inside the mold body 1, an auxiliary component 102 installed at the bottom of the annular groove 101, a heat-conducting layer 103 bonded inside the annular groove 101 and inside the coil 2, and built-in grooves 104 on the left and right sides near the top of the mold body 1, with fixing components 105 installed inside the built-in grooves 104. The coil 2 is installed inside the annular groove 101, with an inlet pipe 201 installed at one end of the coil 2 near the bottom of the annular groove 101, and an outlet pipe 202 installed at the other end of the coil 2 away from the inlet pipe 201. External equipment injects water into the coil through the inlet pipe 201 and finally discharges it through the outlet pipe 202.

[0035] Example 2:

[0036] like Figure 1-4As shown, a wiring groove 106 is provided on the front of the mold body 1, around the water inlet pipe 201 and the water outlet pipe 202. The wiring groove 106 facilitates the installation of the water inlet pipe 201 and the water outlet pipe 202. At the same time, the wiring groove 106 can also limit the coil 2 through the water inlet pipe 201 and the water outlet pipe 202 to prevent it from rotating inside the annular groove 101 during use, thereby improving the stability of use. A molding groove 107 is provided inside the mold body 1, on the inner side of the annular groove 101. The molding groove 107 can support the hot melt plastic injected into it and cooperate with the external moving mold for injection molding. The auxiliary component 102 includes a base plate 1021, which is annular. The stainless steel structure has a first spring 1022 fixedly connected between the bottom of the base plate 1021 and the annular groove 101. The first spring 1022 can push the base plate 1021 downwards, causing the coil 2 above it to be pushed out of the annular groove 101, facilitating the disassembly and replacement of the coil 2 and improving ease of use. The heat-conducting layer 103 is made of heat-conducting graphite sheets with a thickness of 0.5 cm. These graphite sheets have excellent thermal conductivity, chemical stability, and outstanding mechanical strength. The heat-conducting layer 103 allows for more uniform heat exchange in the coil 2, improving the heat exchange and cooling effect. The fixing component 105 includes a push plate 1051, which is slidably connected to the built-in groove 104. An adjusting rod 1052 is rotatably connected to the outer periphery of the mold body 1. A knob 1053 is welded to the end of the adjusting rod 1052 away from the push plate 1051. Limiting rods 1054 are symmetrically welded to the outer side of the push plate 1051 near the front and back. The limiting rods 1054 are slidably connected to the mold body 1. A second spring 1055 is fixedly connected between the end of the limiting rod 1054 away from the push plate 1051 and the mold body 1. The second spring 1055 can push the limiting rod 1054, causing the limiting rod 1054 to move the push plate 1051 inward to the top of the coil 2, thereby fixing the coil 2 and preventing it from detaching from the annular groove 101 during use. The limiting rod 1054 can... The moving push plate 1051 is limited to prevent it from deviating and improve its stability. The push plate 1051 is made of semi-circular stainless steel, and a protective pad is bonded to the inner side where it contacts the heat-conducting layer 103. The protective pad prevents the push plate 1051 from directly contacting the heat-conducting layer 103, thus improving the protection of the heat-conducting layer 103. The knob 1053 has protrusions extending outward from the front and back. Pulling the knob 1053 outward to disengage it from the mold body 1 and rotating it 90 degrees can make the protrusions lock onto the outer periphery of the mold body 1, thereby achieving the purpose of pulling the push plate 1051 into the built-in groove 104 and fixing it, preventing the push plate 1051 from obstructing the removal of the coil 2 and improving the ease of use.

[0037] The working process of this utility model is as follows: When disassembling and replacing the coil in the cooling water channel structure of a precision mold, firstly, pull the knob 1053 outward and rotate it 90 degrees, so that the protrusion on the periphery of the knob 1053 is locked on the outer wall of the mold body 1, thereby fixing the knob 1053. During the process of pulling out the knob 1053, the adjusting rod 1052 and the push plate 1051 will slide outward together, and the push plate 1051 will enter the interior of the built-in groove 104, disengaging from the coil 2. After the fixation of the push plate 1051 is removed, the first spring 1022 will push the base plate 1021, causing it to move the coil 2 upward, thereby pushing the coil 2 out of the interior of the annular groove 101 for replacement. Compared with traditional mold water channels, this device can quickly replace the coil 2, greatly improving the convenience of use and effectively improving the utilization efficiency of the mold body 1.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
