Description

Steel sheet package silica gel mould

Technical Field

The utility model relates to the technical field of dies, in particular to a steel sheet silicon rubber-coated die.

Background

Because the liquid silica gel raw material is very easy to overflow glue (especially steel sheet rubber coating products), the traditional liquid silica gel product needs to be manufactured into a plastic plug firstly and then put into a mold core together with the product during glue sealing and then is molded and sealed, so that the plastic plug needs to be additionally manufactured, and a plurality of plastic molds need to be opened, so that the cost is higher.

Disclosure of Invention

In order to overcome the defects in the prior art, the utility model aims to provide a steel sheet wrapped silica gel mold, which solves the problem of high processing cost of liquid silica gel wrapped products.

The utility model is realized by the following technical scheme:

a steel sheet silicon rubber coating mold comprises a front mold core, a rear mold core and a rubber inlet flow channel arranged on the rear mold core, wherein a plurality of grooves are formed in the flow channel, a bulge is arranged on the periphery of each groove, and the shape of each bulge is matched with the shape of each groove.

Wherein the thickness of the protrusion is 0.010mm to 0.015 mm.

Wherein the width of the protrusion is 0.05mm to 0.1 mm.

The number of the glue inlet runners is two, and the two glue inlet runners are arranged in a mirror image mode relative to the central line of the rear mold core.

Wherein, the bottom end face of recess is equipped with the grid groove.

Wherein, the glue inlet flow channel is communicated with the groove.

The utility model has the beneficial effects that:

the problem of liquid silica gel rubber coating product processing cost is higher is solved: according to the steel sheet silicon rubber-coated mold, the groove is formed in the position of the rubber inlet flow channel and used for containing liquid silicon rubber of a product, when glue is sealed, the front mold core and the rear mold core are closed, glue is poured into the mold cores, the product and the liquid silicon rubber are pressed and molded due to the existence of the protrusions, and meanwhile, the glue sealing is completed. The utility model can be molded by sealing without using a plastic plug, and has lower cost.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

In the description of the present invention, it is to be understood that the terms "central," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the utility model and to simplify the description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are not to be considered limiting of the utility model.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

As shown in fig. 1 to 3, a steel sheet-coated silica gel mold includes a front mold core 100, a rear mold core 200, and a gel inlet runner 201 disposed in the rear mold core 200, wherein a plurality of grooves 202 are disposed in the runner, a protrusion 203 is disposed around each groove 202, and the shape of the protrusion 203 is adapted to the shape of the groove 202.

Specifically, according to the steel sheet silicone rubber-coated mold of the present invention, the groove 202 is disposed at the glue inlet runner 201, the groove 202 is used for accommodating liquid silicone rubber of a product, when glue is sealed, the front mold core 100 and the rear mold core 200 are closed, and glue is poured into the mold cores. In this embodiment, since the depth of the groove 202 is slightly lower than the height of the liquid silicone rubber, the front mold core 100 is closed; due to the existence of the protrusion 203, a pressing space exists between the liquid silicone rubber and the product, the product and the liquid silicone rubber are pressed and molded under the action of the front mold core 100, and the molding is completed. The utility model can be molded by sealing without using a plastic plug, and has lower cost.

Specifically, in order to enable the front mold 100 to be smoothly pressed with the product, the thickness of the protrusion 203 is set to be 0.010mm to 0.015mm, and the width of the protrusion 203 is set to be 0.05mm to 0.1 mm.

Specifically, the number of the glue inlet runners 201 is two, and the two glue inlet runners 201 are arranged in a mirror image manner about the center line of the rear mold core 200, so that the stress on two sides in the mold core is uniform when the front mold core 100 and the rear mold core 200 are closed, and the accuracy of pressing a product and liquid silica gel is improved.

Specifically, the bottom end face of the groove 202 is provided with the grid groove 204, and the liquid silica gel can be positioned through the grid groove 204, so that the liquid silica gel is prevented from displacing during die assembly.

Specifically, the glue inlet flow channel 201 is communicated with the groove 202, so that the liquid silica gel can be conveniently sealed.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the protection scope of the present invention, although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
