Description

Technical Field

[0001] This utility model relates to the technical field of power box production equipment, specifically to a processing mold for a power box cover made of BMC material. Background Technology

[0002] BMC material, short for Bulk Molding Compound, is a molding intermediate material used in the semi-dry manufacturing of glass fiber reinforced thermosetting products.

[0003] To improve the high-temperature resistance of power boxes and make products safer, BMC material power boxes have appeared on the market. Unlike general injection molding materials, BMC material needs to be cured quickly at high temperatures during the molding process. In the current processing of BMC material power boxes, the molding cavity cannot maintain a relatively high temperature, so the BMC material power boxes cannot be cured quickly, resulting in a relatively low product yield.

[0004] Therefore, further improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a processing mold for a power box cover made of BMC material, which can speed up the curing speed of the power box cover in the molding cavity, avoid deformation and shrinkage due to slow molding speed, and improve the yield of power box production.

[0006] The purpose of this utility model is achieved as follows:

[0007] A processing mold for a power supply box cover made of BMC material includes an upper mold base and a lower mold base. The upper mold base and the lower mold base are respectively provided with an upper mold core and a lower mold core. The upper mold base and the lower mold base are connected and cooperate to form a plurality of molding cavities corresponding to the shape of the power supply box between the upper mold core and the lower mold core. A hot water channel is provided in the upper mold base at a position adjacent to the upper mold core. The hot water channel transfers heat between the upper mold core and the molding cavity. A sprue holder is provided below the lower mold base. A sprue cutter is connected to the sprue holder. The sprue cutter passes upward through the lower mold base and the lower mold core and extends to the feed end position of the molding cavity. The sprue holder can drive the sprue cutter to move upward relative to the lower mold base.

[0008] As a specific embodiment, the upper mold base is connected to a flow divider block, and the upper mold base is provided with a flow divider block mounting cavity corresponding to the flow divider block. The flow divider block is embedded in the flow divider block mounting cavity. The flow divider block is provided with an injection port and a water flow channel, and the water flow channel is connected to the injection port and the molding cavity respectively.

[0009] As a specific embodiment, the diversion block is provided with a middle hot water channel. The upper hot water channel includes several upper through slots that penetrate the front and rear ends of the upper mold base. Adjacent upper through slots are connected end to end by external pipes to form a meandering upper hot water channel. The middle hot water channel is connected to the upper hot water channel. The middle hot water channel is located in the diversion block at a position adjacent to the feed end of the forming cavity.

[0010] As a specific solution, a lower hot water channel is provided in the lower mold base at a position adjacent to the lower mold core, and the upper hot water channel and the lower hot water channel are respectively connected to the molding cavity through the upper mold core and the lower mold core.

[0011] As a specific embodiment, the lower hot water channel includes several lower through slots that penetrate the front and rear ends of the lower mold base. Adjacent lower through slots are connected end to end by external pipes to form a meandering lower hot water channel.

[0012] As a specific embodiment, a demolding seat is provided between the lower mold base and the sprue cutter seat. The demolding seat is provided with several demolding pillars. The demolding pillars pass through the lower mold base and the lower mold core in sequence and extend to the bottom of the molding cavity. The demolding seat can drive the demolding pillars to move upward relative to the lower mold base. The sprue cutter passes through the demolding seat vertically.

[0013] The beneficial effects of this utility model are:

[0014] By setting up a hot water channel, a relatively high temperature can be maintained inside the molding cavity, thereby accelerating the molding efficiency of the power box cover and avoiding phenomena such as deformation and shrinkage due to slow molding speed, thus improving the yield rate of power box cover production.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] See Figures 1-3The processing mold for the power box cover made of BMC material includes an upper mold base 1 and a lower mold base 2. The upper mold base 1 and the lower mold base 2 are respectively provided with an upper mold core 3 and a lower mold core 4. The connection and cooperation between the upper mold base 1 and the lower mold base 2 can form a plurality of forming cavities 8 corresponding to the shape of the power box between the upper mold core 3 and the lower mold core 4. The separation of the upper mold base 1 and the lower mold base 2 can allow each forming cavity 8 to open outward, so that multiple power box covers can be processed at the same time each time the mold is closed, thereby improving production efficiency.

[0020] A hot water channel 11 is provided in the upper mold base 1 at a position adjacent to the upper mold core 3. The hot water channel 11 transfers heat to the molding cavity 8 through the upper mold core 3. By setting the hot water channel 11, the molding cavity 8 can maintain a relatively high temperature, thereby accelerating the molding efficiency of the power box cover, avoiding deformation and shrinkage due to slow molding speed, and improving the yield of power box cover production.

[0021] A sprue cutter seat 5 is provided below the lower mold base 2. The sprue cutter seat 5 is connected to a sprue cutter 51. The sprue cutter 51 passes upward through the lower mold base 2 and the lower mold core 4 and extends to the feeding end of the molding cavity 8. The sprue cutter seat 5 can drive the sprue cutter 51 to move upward relative to the lower mold base 2. The sprue cutter seat 5 can drive the sprue cutter 51 to move upward relative to the lower mold base 2, which can reduce the impact of the sprue on the product.

[0022] Furthermore, the upper mold base 1 is connected to a flow divider block 6. The upper mold base 1 is provided with a flow divider block mounting cavity corresponding to the flow divider block 6. The flow divider block 6 is embedded in the flow divider block mounting cavity. The flow divider block 6 is provided with a material injection port 61 and a water flow channel 62. The water flow channel 62 is connected to the material injection port 61 and the molding cavity 8 respectively. The flow divider block 6 can divert the processing material, so that the processing material can be smoothly diverted into the molding cavity 8.

[0023] Furthermore, the diversion block 6 is provided with an intermediate hot water channel 63, and the upper hot water channel 11 includes several upper through slots that penetrate the front and rear ends of the upper mold base 1. Adjacent upper through slots are connected end to end by external pipes to form a meandering upper hot water channel 11. The intermediate hot water channel 63 is connected to the upper hot water channel 11. The intermediate hot water channel 63 is located in the diversion block 6 at a position adjacent to the feed end of the molding cavity 8, so that the molding cavity 8 can maintain a relatively high temperature, thereby accelerating the molding efficiency of the power box, avoiding deformation and shrinkage due to slow molding speed, and improving the yield of power box production.

[0024] Furthermore, a lower hot water channel 21 is provided in the lower mold base 2 at a position adjacent to the lower mold core 4. The lower hot water channel 21 transfers heat between the lower mold core 4 and the molding cavity 8, so that the lower mold core 4 can also have a relatively high temperature, further increasing the temperature of the molding cavity 8.

[0025] Furthermore, the lower hot water channel 21 includes several lower through slots that penetrate the front and rear ends of the lower mold base 2. Adjacent lower through slots are connected end to end by external pipes to form a meandering lower hot water channel 21. There is no need to set up multiple additional water supply systems, so that the upper hot water channel 11 and the lower hot water channel 21 can share the same water supply system.

[0026] Furthermore, a demolding seat 7 is provided between the lower mold base 2 and the sprue cutter seat 5. The demolding seat 7 is provided with several demolding pillars 71. The demolding pillars 71 pass through the lower mold base 2 and the lower mold core 4 in sequence and extend to the bottom of the molding cavity 8. The demolding seat 7 can drive the demolding pillars 71 to move upward relative to the lower mold base 2. The sprue cutter 51 passes through the demolding seat 7 vertically.
