Description

Technical Field

[0001] The present application relates to the technical field of medical protective cover production equipment, and in particular to a medical protective cover production mold. Background Art

[0002] At present, the packaging boxes of medical incubators are generally processed and produced by injection molding or blister molding. Injection molding has high molding quality, small product defects, and high yield, but it is not suitable for use on packaging boxes due to factors such as high processing costs and low efficiency. Therefore, blister molding is generally used in the market for processing.

[0003] However, since the incubator is relatively high, the depth of the incubator may cause product rupture, bubbles, and white spots during the production process using the blister packaging process. Utility Model Content

[0004] In order to solve the above technical problems, the present application provides a medical protective cover production mold, which has the advantage of reducing the problems of bubbles and white spots in the blister process.

[0005] In order to achieve the above object, the technical solution of the utility model is as follows:

[0006] A medical protective cover production mold, comprising a base, a mold body arranged on the base, and a heating assembly for heating the mold body, wherein a pressing member for pressing a material onto the mold body is arranged above the mold body;

[0007] The heating assembly includes a peripheral heating element and a top heating element arranged in the mold body;

[0008] A negative pressure piece for blister packaging is arranged below the base.

[0009] The above technical solution is implemented so that after the plastic sheet raw material is laid on the mold body, the plastic sheet is softened by the heating device on the blister machine, and then the plastic sheet is adsorbed and adhered to the mold body by the negative pressure piece. After the mold body is heated by the heating component, its surface temperature increases, so that the plastic sheet will not cool down when adsorbed on the mold body, thereby ensuring its flexibility after heating and softening, thereby reducing the occurrence of problems such as bubbles, white spots, and breakage caused by excessive angles of the blister draw rope; that is, simultaneous heating by the peripheral heating element and the top heating element can ensure the uniformity of the mold body surface temperature, thereby ensuring the blister shaping effect.

[0010] As a preferred solution of the present application, the peripheral heating element includes a plurality of peripheral heating rods arranged at equal intervals along the outer peripheral edge direction of the mold body.

[0011] To implement the above technical solution, the peripheral side of the mold body is evenly heated by a plurality of peripheral heating rods, thereby ensuring temperature uniformity, and the heating power of the heating rods is controllable, thereby ensuring controllability of the mold body temperature.

[0012] As a preferred solution of the present application, the top heating element includes a heating groove arranged on the top wall of the mold body, a heat conducting plate is arranged in the heating groove, and a horizontal heating rod is arranged on the heat conducting plate.

[0013] By implementing the above technical solution, the heat of the horizontal heating rod can be evenly transferred to the heat conducting plate, and the contact area between the heat conducting plate and the mold body is large, so that the top surface of the mold body is evenly heated, thereby ensuring the temperature uniformity of the mold body, thereby reducing the occurrence of white spots and breakage during blistering.

[0014] As a preferred solution of the present application, the pressing member includes a bracket, on which is provided a silicone ring for pressing the edge of the mold body, and the silicone ring is provided with an arc-shaped guide surface that fits with the mold body.

[0015] The above technical solution is realized by setting an elastic silicone ring and an arc-shaped guide surface to ensure that the raw material is attached to the mold body while reducing the occurrence of crushing and damage of the raw material.

[0016] As a preferred solution of the present application, an adsorption hood is arranged under the base, a bracket for supporting the base is arranged in the adsorption hood, and an adsorption tube for connecting to a negative pressure device is arranged on the bottom wall of the adsorption hood.

[0017] To implement the above technical solution, that is, after the adsorption tube and the negative pressure device (suction fan, etc.) are connected, the negative pressure device will absorb air, thereby generating negative pressure evenly around the base placed on the support frame, so that the raw material on the mold body is precisely fitted to the mold body under the action of negative pressure, thereby ensuring the yield of product molding.

[0018] In summary, the present application includes at least one of the following beneficial technical effects:

[0019] 1. After the plastic sheet raw material is laid on the mold body, the plastic sheet is softened by the heating device on the blister machine, and then the plastic sheet is adsorbed and attached to the mold body by the negative pressure piece. After the mold body is heated by the heating component, its surface temperature rises, so that the plastic sheet will not cool down when adsorbed on the mold body to ensure its flexibility after heating and softening, thereby reducing the occurrence of bubbles, white spots, breakage and other problems caused by excessive angles of the blister draw rope; that is, the surrounding heating element and the top heating element are heated at the same time to ensure the uniformity of the surface temperature of the mold body, thereby ensuring the effect of blister shaping.
