Two sliding blocks are fixed on the sliding block seat, and sliding block cores are respectively connected on the two sliding blocks in a sliding manner.

After the scheme is adopted, because the utility model discloses a cover half bottom plate, fixed die plate, oblique guide pillar, take-up housing, slider core, gyro wheel, movable mould board, location pearl, thimble board, square iron, movable mould bottom plate, gyro wheel and slider core are installed to the outer end of slider core and are passed through the gyro wheel and connect in the inboard spout of slider, and this spout length direction intersects with the moving direction slant of take-up housing for the slider of inclination converts horizontal slider into, in addition, the utility model relates to a big take-up housing drives two little sliders, avoids the interference of two sliders, can accomplish the action of loosing core of product smoothly.

The invention will be further described with reference to the accompanying drawings and specific embodiments.

Detailed Description

As shown in fig. 2-4, the utility model relates to a horizontal slider of little space is loosed core and is changeed double-bevel loose core mould, including cover half bottom plate 1, fixed die plate 2, guide pillar 3 to one side, take-up housing 4, slider 5, slider core 6, gyro wheel 7, movable mould board 8, location pearl 9, thimble 10, thimble board 11, square bar 12, movable mould bottom plate 13.

The top surface of the fixed die plate 2 is fixed on the fixed die bottom plate 1, the upper end of the inclined guide post 3 is fixed on the fixed die plate 2, the lower end of the inclined guide post 3 is movably arranged in an inclined guide post hole 41 of the slide block seat 4 in a penetrating manner, the outer side of the slide block seat 4 is abutted against an inclined wedge 21 on the fixed die plate 2, the slide block seat 4 is connected with the top surface of the movable die plate 8 in a sliding manner, a positioning groove 42 on the bottom surface of the slide block seat 4 can be sleeved with a positioning ball 9 to be positioned, the outer end of the slide block 5 is fixed on the slide block seat 4, the outer end of the slide block core 6 is provided with a roller 7, the slide block core 6 is connected in a slide groove 51 on the inner side of; the movable mould plate 8 is connected with the movable mould bottom plate 13 through the square iron 12, the ejector pin plate 11 is movably installed in a space between the movable mould plate 8 and the movable mould bottom plate 13, the lower end of the ejector pin 10 is fixed on the ejector pin plate 11, and the upper end of the ejector pin 10 penetrates through the movable mould plate 8 and then extends into the cavity.

In this embodiment, two sliders 5 are fixed on the slider seat 4, and slider cores 6 are slidably connected to the two sliders 5, respectively. It should be noted that the number of the sliders 5 may be determined as needed.

The utility model discloses a theory of operation:

as shown in fig. 4-6, in the mold opening operation, the inclined guide post 3 drives the slider seat 4 to horizontally loose core under the mold opening force of the machine, at this time, the roller 7 is fixed with the slider core 6 in the chute 51 of the slider 5 to perform a swing action, so that the slider core 6 can make an inclined motion along the chute 51 of the slider 5, and the horizontal motion is converted into an inclined motion. After the mold is opened, the slider seat 4 is pulled to the position and is positioned by the positioning beads 9. At the moment, the core pulling action is finished, the mold is continuously opened to a certain distance, the ejector pins 10 perform the ejection action under the action of the ejector pin plate 11 to eject the lamp holder product 100, the whole set of action is finished, the mold closing is opposite,
