Description

Technical Field

[0001] The present invention relates to the field of tooling, in particular to cold vulcanization tooling. Background Art

[0002] like Figure 1 As shown, the existing cold vulcanization equipment includes a mold body, which is provided with a mold cavity 4, a glue injection hole 101 and a vent 205; the mold cavity 4 is arranged horizontally, and the glue injection hole 101 and the vent 205 are located above the mold cavity 4.

[0003] During operation, the connector is placed horizontally in the mold cavity, and then vulcanized rubber is injected into the injection hole so that the vulcanized rubber wraps the connector in the membrane cavity to form a rubber sleeve. During the injection process, the gas in the mold cavity is discharged from the exhaust hole.

[0004] The existing cold vulcanization process is to inject glue on the top side, which will form many burrs on the top side of the rubber sleeve. The large number of burrs will affect the appearance and the use of the entire connector and make it difficult to deal with the burrs later. When injecting glue, the bubbles in the mold cavity move upward, and a large number of bubbles will be concentrated on the top of the mold cavity, then many bubble holes will appear on the top side of the rubber sleeve. The large number of bubble holes will affect the airtightness of the rubber sleeve. Summary of the Invention

[0005] The purpose of the present invention is to provide a cold vulcanization equipment for the above-mentioned problems, which can reduce burrs and air bubbles on the side of the rubber sleeve.

[0006] The technical solution adopted in the present invention is as follows:

[0007] A cold vulcanizing equipment, comprising a left mold body and a right mold body;

[0008] The front surface of the left mold body is provided with a glue injection hole, a left half mold cavity and a left half positioning hole which are connected in sequence from top to bottom; the upper end of the glue injection hole passes through the top of the left mold body, and the lower end of the left half positioning hole passes through the bottom of the left mold body;

[0009] The front surface of the right mold body is provided with a wire positioning hole, a right half mold cavity and a right half positioning hole which are connected in sequence from top to bottom; the upper end of the wire positioning hole passes through the top of the left mold body, and the lower end of the right half positioning hole passes through the bottom of the right mold body;

[0010] The top of the right mold body is provided with an exhaust hole, the exhaust hole is located outside the wire positioning hole, the upper end of the exhaust hole passes through the top of the right mold body, and the lower end of the exhaust hole is connected to the upper end of the right half mold cavity;

[0011] When the front of the left mold body contacts the front of the right-left mold body, the left half mold cavity and the right half mold cavity are spliced into a mold cavity, the left half positioning hole and the right half positioning hole are spliced into a positioning hole, and the central axes of the glue injection hole, the wire positioning hole, the mold cavity and the positioning hole coincide.

[0012] Furthermore, the glue injection hole and the wire positioning hole are both connected at the upper and lower ends, and are semicircular holes with a front opening. The diameter of the glue injection hole is larger than the diameter of the wire positioning hole.

[0013] Furthermore, the glue injection hole is in the shape of a funnel that is larger at the top and smaller at the bottom.

[0014] Furthermore, the exhaust hole is located on the back side of the wire positioning hole.

[0015] Furthermore, a glue overflow groove with a top opening is provided on the top of the right plate mold cavity, and the glue overflow groove is connected to the exhaust hole.

[0016] Furthermore, the bottom surface of the overflow glue groove extends downward so that the bottom surface of the overflow glue groove is flush with the upper end of the right half mold cavity. One end of the overflow glue groove extends toward the front of the right mold body, passing through the exhaust hole and the wire positioning hole in sequence; the other end of the overflow glue groove extends toward the back of the right mold body, passing through the back of the right mold body.

[0017] Furthermore, the top surface of the right mold body is higher than the top surface of the left mold body, so that the upper end of the glue injection hole is located below the top surface of the right mold body.

[0018] Furthermore, on the front side of the left mold body, the opening edge of the left half mold cavity is provided with a chamfer; on the front side of the right mold body, the opening edge of the right half mold cavity is provided with a chamfer.

[0019] Furthermore, the left mold body and the right mold body are detachably connected by bolts.

[0020] Furthermore, the diameter of the positioning hole matches the diameter of the connector head; the diameter of the wire positioning hole matches the diameter of the wire.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0022] Because the present invention utilizes tail-filling, burrs on the sleeve are primarily concentrated at the rear end, rather than on the sides. Bubbles are discharged upward, and pores are primarily concentrated at the rear end, rather than on the sides. Because the rear end is smaller than the side, fewer burrs and pores form, facilitating subsequent handling. Furthermore, because the sides of the sleeve are working surfaces, while the rear end is not, burrs and pores are concentrated at the rear end, minimizing the overall usability of the product.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0035] like Figures 1 to 6 As shown, the present invention discloses a cold vulcanization process equipment, which includes a left mold body 1 and a right mold body 2; the front surface of the left mold body 1 is provided with a glue injection hole 101, a left half mold cavity 102 and a left half positioning hole 103 which are connected in sequence from top to bottom; the upper end of the glue injection hole 101 passes through the top of the left mold body 1, and the lower end of the left half positioning hole 103 passes through the bottom of the left mold body 1;

[0036] The front surface of the right mold body 2 is provided with a wire positioning hole 201, a right half mold cavity 202 and a right half positioning hole 203 which are connected in sequence from top to bottom; the upper end of the wire positioning hole 201 passes through the top of the left mold body 1, and the lower end of the right half positioning hole 203 passes through the bottom of the right mold body 2;

[0037] The top of the right mold body 2 is provided with an exhaust hole 205, which is located outside the wire positioning hole 201. The upper end of the exhaust hole 205 passes through the top of the right mold body 2, and the lower end of the exhaust hole 205 is connected to the upper end of the right half mold cavity 202;

[0038] When the front of the left mold body 1 contacts the front of the right-left mold body 1, the left half mold cavity 102 and the right half mold cavity 202 are spliced into the mold cavity 4, the left half positioning hole 103 and the right half positioning hole 203 are spliced into the positioning hole 3, and the central axes of the glue injection hole 101, the wire positioning hole 201, the mold cavity 4 and the positioning hole 3 coincide.

[0039] Due to the above structure, when working, first put the connector head 1001 into the right half positioning hole 203, put the connector body 1002 into the right half mold cavity 202, put the wire 1003 into the wire positioning hole 201, and then cover the left half mold body; make the connector head 1001 located in the positioning hole 3, restrict the movement of the connector head 1001, and make the connector body 1002 located in the mold cavity 4 waiting for glue injection. When injecting glue, the entire connector is set vertically, with the connector head 1001 facing down and the tail facing up. When injecting glue, vulcanized rubber is injected into the injection hole 101, and the vulcanized rubber flows into the mold cavity 4 from the injection hole 101 by its own gravity. In the process of continuously flowing into the mold cavity 4, the bubbles generated will be discharged from the exhaust hole 205. Since the present invention injects glue from the tail, the wire 1003 acts as a natural mold cavity 4 divider, dividing the mold cavity 4 into two halves, so that the vulcanized rubber and the generated bubbles are separated as much as possible, so that the bubbles can be discharged smoothly.

[0040] Because the present invention utilizes tail-filling, burrs on the sleeve are primarily concentrated at the rear end, rather than on the sides. Bubbles are discharged upward, and pores are primarily concentrated at the rear end, rather than on the sides. Because the rear end is smaller than the side, fewer burrs and pores form, facilitating subsequent handling. Furthermore, because the sides of the sleeve are working surfaces, while the rear end is not, burrs and pores are concentrated at the rear end, minimizing the overall usability of the product.

[0041] like Figure 2 、 3 As shown, the glue injection hole 101 and the wire positioning hole 201 are both through-holes at the upper and lower ends, and are semicircular holes with an opening on the front. The diameter of the glue injection hole 101 is larger than the diameter of the wire positioning hole 201, and the diameter of the wire positioning hole 201 matches the diameter of the wire 1003; the diameter of the positioning hole 3 is larger than the diameter of the lower end of the mold cavity 4, and the diameter of the positioning hole 3 matches the diameter of the connector head 1001.

[0042] The diameter of the wire positioning hole 201 matches the diameter of the wire 1003, ensuring that the wire 1003 is stably positioned within the guide positioning hole 3 and preventing the wire 1003 from moving or deviating from the axis of the mold cavity 4 during the glue injection process. The diameter of the positioning hole 3 matches the diameter of the connector head 1001, preventing the connector body 1002 from moving within the mold cavity 4 or deviating from the axis of the mold cavity 4. The diameter of the glue injection hole 101 is larger than the diameter of the wire 1003, facilitating glue injection. Because the glue injection hole 101 is a semicircular hole and larger than the diameter of the wire 1003, an arc-shaped outlet exists between the glue injection hole 101 and the wire 1003. The glue flows into the mold cavity 4 along the arc-shaped outlet, making the glue injection more uniform.

[0043] Furthermore, the glue injection hole 101 is in the shape of a funnel with a larger top and a smaller bottom. When the glue fills the funnel, it flows out naturally along the arc-shaped outlet under the action of gravity, which can ensure uniform glue injection.

[0044] Furthermore, the vent hole 205 is located at the back of the wire positioning hole 201. The farther the vent hole 205 is from the glue injection hole 101, the more it can prevent the vulcanized glue from mistakenly entering the vent hole 205 and blocking the vent hole 205.

[0045] Furthermore, a glue overflow groove 204 with a top opening is provided on the top of the right plate mold cavity 4 , and the glue overflow groove 204 is communicated with the exhaust hole 205 .

[0046] Due to the presence of the overflowing glue groove 204, when the mold cavity 4 is filled with glue, the glue overflows from the exhaust port into the overflowing glue groove 204. This makes it easy to judge whether the overflowing mold cavity 4 is filled.

[0047] like Figure 3 、 4 As shown, the bottom surface of the overflow glue groove 204 extends downward, so that the bottom surface of the overflow glue groove 204 is flush with the upper end of the right half mold cavity 202. One end of the overflow glue groove 204 extends toward the front of the right mold body 2, sequentially passing through the exhaust hole 205 and the wire positioning hole 201; the other end of the overflow glue groove 204 extends toward the back of the right mold body 2, passing through the back of the right mold body 2. The overflow glue groove 204 is formed as a through groove, which facilitates processing.

[0048] Further, such as Figure 6 As shown, the top surface of the right mold body 2 is higher than the top surface of the left mold body 1, so that the upper end of the glue injection hole 101 is located below the top surface of the right mold body 2. This can prevent the glue in the glue injection hole 101 from entering the vent 205 and prevent the vent from being blocked by the glue.

[0049] Furthermore, on the front side of the left mold body 1 , the opening edge of the left half mold cavity 102 is chamfered; on the front side of the right mold body 2 , the opening edge of the right half mold cavity 202 is chamfered.

[0050] When the left and right mold halves 102 and 202 are joined, the chamfered corners create a small groove. This small groove can accommodate any bubbles that are delayed during the vulcanization process. Because the groove is small, any burrs that form can be easily removed, further reducing the generation of air bubbles within the rubber sleeve. The chamfer size is C0.2.

[0051] Furthermore, the left mold body 1 and the right mold body 2 are detachably connected by bolts.

[0052] To facilitate demoulding, the roughness of the mold cavity 4 is 0.1 μm, the roughness of the left mold body 1 and the right mold body 2 is 0.4 μm, and the roughness of the remaining parts is 3.2 μm.

[0053] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
