Description

Technical Field

[0001] This invention relates to a rubber mold for a cable outlet retainer, belonging to the field of rubber mold technology. Background Technology

[0002] When using rubber for hot extrusion molding of a wire guide with a raised outer ring, the raised outer ring can cause obstruction if vertical demolding is used. Existing technology (see Chinese Patent Publication No. CN218111467U) uses two ferrules distributed on both sides for joining; although this facilitates separation and demolding from the left and right sides, it leads to excessive length of the two ferrules when a multi-cavity mold is required. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a rubber mold for a cable outlet retainer.

[0004] The present invention is achieved through the following technical solutions.

[0005] The present invention provides a rubber mold for a cable outlet retainer, comprising: A mold with three haver blocks.

[0006] The three Haval blocks are composed of three blocks: Haval A, Haval B, and Haval C. It includes a lower template for installing the Haval block; the top surface of the lower template has a lower groove in the middle, the lower groove has a boss in the middle, and a number of core rod groups are fixed on the boss, each core rod group has four core rods; the multiple core rod groups are distributed in two rows on the boss.

[0007] A Haval A is installed in the middle of the two columns of protrusions, and Haval B and Haval C are installed on the sides of the two columns of protrusions respectively; The Haval A, Haval B, and Haval C extend outwards through the lower grooves of the lower template at both ends, and the Haval B and Haval C on both sides contact the lower grooves through inclined surfaces.

[0008] The Haval A has multiple spaced semi-formed grooves A on both sides, and the Haval B and Haval C, which are closer to the Haval A, also have multiple spaced semi-formed grooves B on their sides. The semi-formed grooves A and B wrap around the core rod assembly.

[0009] It also includes a middle template that is installed by positioning and cooperating with the lower template through pins, so that a cavity for forming the supply line fixing product is formed between the bottom surface of the middle template, the top surface of the boss, and Haval A, Haval B, and Haval C. There are multiple cavities, and there are core rod assemblies in the cavities.

[0010] The lower template and the middle template are each provided with a mold release opening A at their four corners.

[0011] The cable outlet fixing product includes a cylindrical body with a raised outer ring A at the top and a raised outer ring B in the middle; the middle of the cylindrical body has four spaced cable outlet holes.

[0012] The top surface of the template is provided with a material receiving groove, and the bottom of the material receiving groove is provided with a material injection hole. There are multiple material injection holes, and each material injection hole corresponds to the top of the core rod.

[0013] It also includes an upper template that is installed by positioning and cooperating with the middle template through pins. The bottom of the upper template has an extrusion table, which corresponds to the material receiving groove.

[0014] The middle template and the upper template are each provided with a mold release opening B at their four corners.

[0015] The beneficial effects of this invention are as follows: Haval A has multiple semi-molded grooves A on both sides, and Haval B and Haval C each have multiple semi-molded grooves B corresponding to the semi-molded grooves A, enabling this application to form a mold structure with multiple cavities in one mold, thus solving the problem that using two Haval pieces would result in excessively long lengths when there is a need for a mold with multiple cavities in one mold.

Detailed Implementation

[0017] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0018] like Figures 1 to 5 As shown.

[0019] This application discloses a rubber mold for a cable outlet retainer, comprising: The lower template 1 is used to install the Haval blocks. The Haval blocks consist of three parts: Haval A2, Haval B3, and Haval C4.

[0020] The lower template 1 has a groove in the middle of its top surface, and a boss 11 in the middle of the groove. Multiple core rod groups 12 are fixed on the boss 11, and each core rod group 12 consists of four core rods spaced apart. The multiple core rod groups 12 are arranged in two rows on the boss 11.

[0021] A Haval A2 is installed between the two columns of protrusions 11, and Haval B3 and Haval C4 are installed on the two sides of the two columns of protrusions 11 respectively. The two ends of Haval A2, Haval B3 and Haval C4 extend outward through the lower groove of the lower template 1, and the Haval B3 and Haval C4 on both sides are in contact with the lower groove through the inclined surface.

[0022] The Haval A2 has multiple spaced semi-formed grooves A21 on both sides, and the Haval B3 and Haval C4, which are close to the Haval A2, have multiple spaced semi-formed grooves B34 on their sides. The semi-formed grooves A21 and B34 wrap around the core rod assembly 12.

[0023] It also includes a middle template 5 that is positioned and installed by a pin and a lower template 1, so that a cavity for forming the supply line fixing product 7 is formed between the bottom surface of the middle template 5, the top surface of the boss 11, and Haval A2, Haval B3, and Haval C4. There is a core rod assembly 12 inside the cavity, and there are multiple cavities.

[0024] The lower template 1 and the middle template 5 are each provided with a mold release opening A53 at their four corners.

[0025] The cable outlet fixing product 7 includes a cylindrical column 71 with a raised outer ring A72 at the top and a raised outer ring B74 in the middle. The middle of the column 71 has four spaced cable outlet holes 73, which are formed by a core rod.

[0026] The Haval A2 has eight semi-molding grooves A on each side, for a total of sixteen semi-molding grooves A on both sides. The Haval B3 and Haval C4 each have eight semi-molding grooves B, enabling this application to form a mold structure with sixteen cavities in one mold. This solves the problem that using two Haval pieces would result in excessive length of the two Haval pieces when there is a need for a mold with multiple cavities.

[0027] The top surface of the middle template 5 is provided with a material receiving groove 51, and the bottom of the material receiving groove 51 is provided with an injection hole 52. There are multiple injection holes 52, and each injection hole 52 corresponds to the top of the core rod. After the rubber material is placed in the material receiving groove 51 and pressed down by hot pressing, the rubber can be guided by the core rod when it is injected into the lower cavity through the injection hole 52.

[0028] It also includes an upper template 6, which is installed by positioning and engaging with the middle template 5 via pins. An extrusion table 61 is integrally fixedly connected to the bottom of the upper template 6, and the extrusion table 61 corresponds to the material receiving groove 51. Each of the four corners of the middle template 5 and the upper template 6 is provided with a mold release pry hole B62.
