Description

Technical Field

[0001] This utility model relates to the field of casting mold technology, specifically to a casting mold for epoxy resin insulation that facilitates venting. Background Technology

[0002] Epoxy resin insulation casting molds are specialized tools used to produce epoxy resin insulation components. Through a casting process, liquid epoxy resin is injected into the mold cavity, and after curing, it forms an insulating component with a specific shape and size. However, common casting molds generate a lot of residual air bubbles inside during the casting process, which are not easy to remove. This causes internal defects in the insulation component due to the retention of air bubbles, which in turn affects the casting operation of epoxy resin insulation components.

[0003] Chinese utility model patent CN223383802U discloses a highly versatile resin casting mold, which includes "a base plate, a soft pad, an inner mold, an outer mold, a first clamping assembly, a second clamping assembly, an adjusting assembly, a wiring board, and an overflow plate; the soft pad is installed on the top surface of the base plate, the inner mold and the outer mold are respectively installed on the top surface of the soft pad, the inner mold is located inside the outer mold, the outer wall of the inner mold and the inner wall of the outer mold are polished surfaces, the overflow plate is detachably installed on the outer mold, and the overflow plate is provided with an overflow port"; however, when using the casting mold to cast epoxy resin, the residual air bubbles in the mold are often difficult to remove, and the residual air bubbles in the mold can easily cause defects in the epoxy resin insulation parts during solidification, thereby affecting the casting effect of the epoxy resin insulation parts. Utility Model Content

[0004] The purpose of this utility model is to provide a casting mold for epoxy resin insulation that facilitates air venting, in order to solve the problem mentioned in the background art that when using a casting mold to cast epoxy resin, the residual air bubbles in the mold are often difficult to remove, and the residual air bubbles in the mold can easily cause defects in the epoxy resin insulation parts during solidification, thereby affecting the casting effect of the epoxy resin insulation parts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an epoxy resin insulating casting mold for easy venting, comprising an outer mold, an inner mold core installed inside the outer mold, a sealing cover installed on the top of the outer mold, an overflow pipe installed at one end of the top of the sealing cover, and multiple venting pipes installed on the top of the sealing cover.

[0006] The bottom of the exhaust pipe is embedded with a guide groove, the top of the guide groove is fixedly connected to a limiting block, the outside of the limiting block is provided with a connecting pipe, the top of the limiting block is provided with an exhaust chamber, and the outer wall of the exhaust chamber is provided with an exhaust hole.

[0007] The beneficial effects of this utility model are as follows: by setting multiple sets of exhaust pipes, air bubbles inside the epoxy resin insulation mold are quickly vented during the casting operation. The inverted funnel-shaped guide groove at the bottom guides the air bubbles, preventing them from accumulating at the top of the casting mold and affecting the casting effect of the insulation. At the same time, the internal limiting block and the inwardly inclined connecting pipe at the bottom, together with the overflow pipe, are used to observe the overflow situation in the casting mold, preventing epoxy resin from overflowing from the exhaust pipe and causing blockage of the exhaust pipe, thereby improving the use effect of the casting mold.

[0008] To enable the replacement of the inner mold core in the outer mold:

[0009] The inner mold core is further configured such that a plurality of mounting screws are installed at the bottom of the inner mold core, and mounting nuts are connected to the external threads of the mounting screws. The mounting screws penetrate the bottom of the outer mold, and the bottom of the inner mold core is in contact with the inner wall of the bottom of the outer mold, and the mounting nuts are in contact with the outer wall of the bottom of the outer mold.

[0010] By adopting the above technical solution, bolts are set at the bottom of the inner mold core to fix it to the outer mold in an external manner. This makes it easy to replace different styles of inner mold cores according to the casting shape requirements of the insulation parts, improves the adaptability of the casting mold, and thus better meets the casting requirements of epoxy resin insulation parts.

[0011] To achieve the mating and fixing of the sealing cap:

[0012] Further configuration: a pouring port is installed at one top end of the sealing cap; multiple connecting screws are evenly distributed around the outer wall of the top of the sealing cap; a threaded hole corresponding to the position of the connecting screw is embedded in the top of the outer mold; an annular protrusion is provided at the bottom of the sealing cap; the annular protrusion at the bottom of the sealing cap is inserted into the top of the outer mold; and the connecting screw and the threaded hole are threadedly connected to each other.

[0013] By adopting the above technical solution, a screw is set on the outside of the sealing cover and connected to the top of the outer mold to fix the sealing cover and the outer mold. This makes it easy to rotate the screw to quickly open and close the sealing cover. The protrusion at the bottom of the sealing cover and the groove at the top of the outer mold can be quickly connected to improve the installation efficiency of the sealing cover and facilitate the discharge of the insulation parts after casting.

[0014] To allow for observation of overflow within the mold during casting:

[0015] The sealing cover is further configured such that: an embedded groove is embedded in the top of the other end of the sealing cover, an overflow pipe is installed in the center of the embedded groove, the overflow pipe is a square tubular structure with its bottom penetrating the embedded groove, a transparent viewing window is installed around the overflow pipe, and a scale strip is installed on one side of the outer wall of the viewing window.

[0016] By adopting the above technical solution, an embedded overflow pipe is set up in conjunction with a viewing window and a scale to observe the overflow of epoxy resin during the pouring of the mold. This avoids the overflow caused by excessive epoxy resin pouring due to mold sealing, thereby improving the performance of the pouring mold.

[0017] To achieve the removal of air bubbles inside the mold:

[0018] The exhaust pipe is further configured such that: an inverted funnel-shaped guide groove is embedded in the bottom of the exhaust pipe, and the top of the guide groove penetrates the bottom of the connecting pipe, and the top of the connecting pipe penetrates the bottom of the exhaust chamber; there are multiple connecting pipes, all of which are annularly embedded inside the exhaust pipe, and the bottom of the connecting pipe is configured as an inwardly inclined curved pipe structure.

[0019] By adopting the above technical solution, an inverted funnel-shaped guide groove is set at the bottom of the exhaust pipe to facilitate the guidance of air bubbles into the guide groove and then into the exhaust chamber through the connecting pipe for exhaust operation. At the same time, a limiting block is set to block the epoxy resin in conjunction with the inclined connecting pipe at the bottom, so as to prevent the epoxy resin from directly entering the exhaust chamber through the exhaust pipe and causing overflow. At the same time, it is easier for air bubbles to enter the exhaust chamber along the connecting pipe and be discharged from the exhaust hole, thereby improving the exhaust effect of the exhaust pipe.

[0020] To prevent epoxy resin from overflowing from the mold:

[0021] The exhaust pipe is further configured such that it is evenly installed at the front and rear ends of the top of the sealing cover, and the interior of the exhaust chamber has multiple sets of exhaust holes that pass through it in a ring shape, and the bottom height of the exhaust chamber is the same as the top height of the overflow pipe.

[0022] By adopting the above technical solution, the bottom height of the venting chamber and the top height of the overflow pipe are set to the same height. This allows for observation of the internal epoxy resin through the overflow pipe, thereby controlling the injection rate at the gate and preventing excessive overflow of internal epoxy resin from the venting pipe. This improves the performance of the casting mold.

[0023] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

A connecting pipe 503 is provided on the outside of the limiting block 502. An exhaust chamber 504 is provided on the top of the limiting block 502. An exhaust hole 505 passes through the outer wall of the exhaust chamber 504.

[0033] In this embodiment, as Figure 1 and Figure 2 As shown, multiple mounting screws 201 are installed at the bottom of the inner mold core 2. The mounting screws 201 are connected to mounting nuts 202 by external threads. The mounting screws 201 pass through the bottom of the outer mold 1, and the bottom of the inner mold core 2 is in contact with the inner wall of the bottom of the outer mold 1, and the mounting nuts 202 are in contact with the outer wall of the bottom of the outer mold 1.

[0034] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a pouring port 301 is installed at one end of the top of the sealing cover 3. Multiple connecting screws 302 are evenly distributed around the outer wall of the top of the sealing cover 3. The top of the outer mold 1 is embedded with threaded holes corresponding to the positions of the connecting screws 302. The bottom of the sealing cover 3 is provided with an annular protrusion. The annular protrusion at the bottom of the sealing cover 3 is inserted into the top of the outer mold 1. The connecting screws 302 and the threaded holes are threaded together.

[0035] In this embodiment, as Figure 3 and Figure 4 As shown, the top of the other end of the sealing cover 3 is embedded with an inset groove 303. An overflow pipe 4 is installed in the center of the inset groove 303. The overflow pipe 4 is a square tubular structure with its bottom penetrating the inset groove 303. A transparent viewing window 401 is installed around the overflow pipe 4. A scale strip 402 is installed on one side of the outer wall of the viewing window 401.

[0036] In this embodiment, as Figure 2 , Figure 3 and Figure 5 As shown, an inverted funnel-shaped guide groove 501 is embedded in the bottom of the exhaust pipe 5, and the top of the guide groove 501 penetrates the bottom of the connecting pipe 503, and the top of the connecting pipe 503 penetrates the bottom of the exhaust chamber 504. There are multiple connecting pipes 503, all of which are annularly embedded inside the exhaust pipe 5, and the bottom of the connecting pipe 503 is set as an inwardly inclined curved pipe structure.

[0037] In this embodiment, as Figure 1 , Figure 3 and Figure 5 As shown, the exhaust pipe 5 is evenly installed at the front and rear ends of the top of the sealing cover 3, and multiple sets of exhaust holes 505 are circumferentially penetrating the interior of the exhaust chamber 504, and the bottom height of the exhaust chamber 504 is the same as the top height of the overflow pipe 4.

[0038] The working process of this epoxy resin insulating and vent-friendly casting mold is as follows:

[0041] Next, the epoxy resin to be poured is poured in through the pouring port 301 at one end of the sealing cap 3, and the volume of the internal epoxy resin is observed through the viewing window 401 and scale bar 402 in the overflow pipe 4 at the other end of the sealing cap 3. At this time, the excess gas during internal pouring is guided to the bottom of the limiting block 502 through the inverted funnel-shaped guide groove 501 at the bottom of the exhaust pipe 5, and transported to the exhaust chamber 504 through the connecting pipe 503, and discharged from the exhaust hole 505 at the top.

[0042] Finally, when the volume of the internal epoxy resin pouring reaches the corresponding scale bar 402 position in the overflow pipe 4, the overall epoxy resin pouring operation is completed. After solidification, the sealing cover 3 can be opened to remove the insulating parts.
