Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, specifically a core-pulling mechanism and a six-way core-pulling vulcanizing mold. Background Technology

[0002] Existing vulcanizing molds typically have core-pulling capabilities in four directions: up / down, front / back, or up / down, left / right. The double-peak damping hydraulic bushing main spring injection vulcanization process requires core-pulling in six directions. To meet the processing requirements, the cores in two directions are usually designed as movable cores. During vulcanization, operators assemble the movable cores, and after vulcanization, the operators remove the movable cores from the line. However, this production method results in poor mold fitting accuracy, high labor intensity, and difficulty in mold storage. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a core-pulling mechanism and a six-way core-pulling vulcanizing mold, which improves product quality, reduces labor intensity, and facilitates mold storage.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a core-pulling mechanism, including a slider, a movable core, a driving block, a connecting member, and a spring stop; the front end of the movable core is provided with a tapered parting surface, and the rear end of the movable core is fixedly connected to the slider; the driving block is used to drive the slider to slide back and forth; the front end of the connecting member passes through the spring stop and is connected to the slider, and a reset spring is provided between the rear end of the connecting member and the spring stop for resetting the slider.

[0005] A further improvement is that the driving block is vertically and vertically positioned above the slider, and a pressing slope is provided on the lower front side of the driving block; a pressure-bearing slope adapted to the pressing slope is provided on the upper rear side of the slider.

[0006] A further improvement is that a limiting protrusion is provided at the upper end of the driving block, and the driving block is embedded in the upper template through the limiting protrusion.

[0007] A further improvement is that the slider is provided with mounting holes for installing the movable core and connecting holes for connecting the connector.

[0008] A further improvement is that the movable core is interference-fitted into the mounting hole, and a positioning block is provided at the rear end of the movable core, and a positioning groove adapted to the positioning block is provided in the mounting hole.

[0009] A further improvement is that the spring stop is provided with a through hole for the connecting piece to pass through, and the lower end of the spring stop is fixedly mounted on the lower template by a base.

[0010] A further improvement is that the slider is slidably mounted on the lower template via a groove or guide bar.

[0011] A further improvement is that the connecting member includes a screw and a limiting sleeve fixedly sleeved on the screw. The front end of the screw extends out from the limiting sleeve and is connected to the slider. The rear end of the limiting sleeve is provided with a flange. The return spring is sleeved on the limiting sleeve, and one end of the return spring abuts against the flange, while the other end of the return spring abuts against the spring stop.

[0012] This utility model also provides a six-way core-pulling vulcanizing mold for a double-peak damping hydraulic bushing, including an upper template, a lower template, and two half-bolts. The lower template is provided with a lower mold insert, and the upper template is provided with an upper mold insert corresponding to the lower mold insert. The two half-bolts are disposed between the upper template and the lower template, and are respectively located on the longitudinal sides of the lower mold insert. A wedge block for driving the half-bolt to translate is provided on the outer side of the half-bolt. It also includes two core-pulling mechanisms as described above, which are respectively located on the transverse sides of the lower mold insert, and the travel of the core-pulling mechanism is less than the travel of the half-bolt.

[0013] A further improvement is that a material-receiving plate and a flow channel plate are sequentially arranged on the upper template.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, by setting a spring or other reset mechanism at the slider, two additional core-pulling directions are added in the conventional core-pulling direction, which reduces the labor intensity of the vulcanization process and is beneficial to mold storage.

[0016] 2. In this utility model, a drive block + slider structure is adopted, and the parting surface is matched with a conical surface, which has high matching accuracy and small flash on the product.

[0017] 3. In this utility model, the parting surface of the movable core adopts a tapered fit, which on the one hand prevents the movable core from bumping, and on the other hand helps to improve the sealing effect. Attached Figure Description
