Description

Technical Field

[0001] This utility model relates to the field of silicone product technology, specifically to a processing mold for a single-row medical multi-frequency device fixing seat silicone base that is easy to demold. Background Technology

[0002] Based on the manufacturing process, silicone products can be divided into compression molding silicone, extrusion silicone, and liquid silicone. Compression molding silicone products are usually formed by placing solid silicone raw materials with added vulcanizing agents into a high-temperature mold and then applying pressure through a vulcanizing machine to solidify them at high temperature. Extrusion silicone products are usually formed by extruding silicone through an extrusion machine. Generally, extruded silicone is in the shape of long strips or tubes and can be cut at will. Liquid silicone products are formed by injection molding. The products are soft and the hardness can reach 10°C-40°C. Due to its softness, it is widely used in simulated human organs, medical silicone breast pads, etc.

[0003] The above technical conditions also have some drawbacks: most existing silicone seat processing molds adopt an integrated structure, which can easily cause the silicone seat to stick or deform during demolding, making demolding inconvenient.

[0004] Based on this, this utility model designs a single-row medical multi-frequency device fixing silicone base processing mold that is easy to demold, in order to solve the above problems. Utility Model Content

[0010] Preferably, temperature sensors are provided at both the inlet and outlet ends of the insulation channel and the cooling channel.

[0011] By adopting the above technical solution, precise control of the heat preservation and cooling process can be achieved, avoiding the instability of silicone performance caused by temperature fluctuations.

[0013] By adopting the above technical solutions, the insulation block reduces heat exchange and improves the effect of gradient temperature control.

[0014] Preferably, both the lower guide plate and the upper guide plate are provided with guide grooves.

[0015] By adopting the above technical solution, linear guidance is provided during mold closing, ensuring axial alignment of all mold components, improving mold closing accuracy and consistency of silicone seat molding.

[0016] In summary, this application has the following beneficial technical effects:

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0027] A mold for processing a single-row medical multi-frequency device fixing silicone seat that facilitates demolding includes a bottom mold 1, a top mold 2, an upper middle mold 3, and a lower middle mold 4. The upper middle mold 3 and the lower middle mold 4 are combined into a middle mold, which is fixedly connected. After the bottom mold 1, top mold 2, and middle mold are closed, a molding hole for the silicone seat is formed. After subsequent silicone is poured, it cools and solidifies. Lower guide plates 5 are fixedly connected to both sides of the bottom mold 1. A lower mold core 6 is provided at the top of the bottom mold 1. Upper guide plates 7 are fixedly connected to both sides of the top mold 2. An upper mold core 8 is provided at the bottom of the top mold 2. A molding cavity 10 is provided inside the upper middle mold 3 and the lower middle mold 4, which is adapted to the lower mold core 6 and the upper mold core 8. Multiple positioning holes 11 are provided on the upper middle mold 3 and the lower middle mold 4 for positioning and guidance during mold closing. By molding the silicone seat in a modular manner, its demolding efficiency can be improved.

[0028] Furthermore, a heat-insulating channel 12 is provided inside the upper mold 3 to maintain the fluidity of the silicone while keeping it warm, and a cooling channel 13 is provided inside the lower mold 4 to achieve rapid shaping at low temperature. The channel configuration is as follows: Figure 4 As shown, the heat preservation channel 12 and the cooling channel 13 are respectively connected to the external liquid exchange control equipment.

[0029] Furthermore, temperature sensors 19 are installed at both the inlet and outlet ends of the insulation channel 12 and the cooling channel 13, which can monitor the gradient temperature in real time, thereby facilitating subsequent adjustment of the insulation temperature or cooling temperature.

[0030] Furthermore, heat insulation blocks 14 are provided on both sides of the upper middle mold 3 and the lower middle mold 4. The heat insulation blocks 14 are made of solid materials with low thermal conductivity. Positioning plates 15 are fixedly connected to the outer side of both sets of heat insulation blocks 14. Alignment holes 16 corresponding to positioning holes 11 are opened on both sets of heat insulation blocks 14. Then, corresponding guide pillars are inserted to achieve precise alignment of the mold. Snap-fit ​​pillars 17 are fixedly connected to both ends of one set of heat insulation blocks 14, and snap-fit ​​grooves 18 are opened at both ends of the other set of heat insulation blocks 14, so that the two sets of heat insulation blocks 14 can be installed more stably on the middle mold.

[0031] Furthermore, guide grooves 9 are provided on both the lower guide plate 5 and the upper guide plate 7, which are used to guide the guide plates when driving them, thereby improving the mold closing effect.

[0032] The implementation principle of this embodiment is as follows: When the mold is closed, the guide groove 9 guides the lower guide plate 5 and the upper guide plate 7 to align. The positioning hole 11 and the alignment hole 16 achieve precise mold closing through the guide post. After the silicone is injected into the molding cavity 10, the heat preservation channel 12 is filled with constant temperature fluid to maintain the fluidity of the silicone, and the cooling channel 13 is filled with coolant to accelerate curing. The temperature sensor 19 monitors in real time, and the external equipment dynamically adjusts the fluid temperature. When demolding, the top mold 2, bottom mold 1 and upper middle mold 3 and lower middle mold 4 are separated, and then the silicone seat can be quickly removed. The whole process achieves efficient and low-loss silicone seat production through modular structure and temperature gradient control.
