As an improvement of the above technical solution, a positioning block is arranged on the outside of the product forming part, which is fixed to both ends of the product forming part through the inclined guide pillars. When the upper mold and the lower mold are in the mold opening state, the inclined guide The columns and row blocks are opened successively.

As an improvement of the above technical solution, the top roller is arranged at the bottom of the lower mold, and above it is the bottom plate of the thimble, the thimble is installed in the air intake pipe, the top of the air intake pipe is located in the forming mold, and its lower end is connected to the bottom plate of the lower mold. The two intake valves are connected, and the thimble bottom plate drives the thimble upwards to open the intake valve under the push of the top roller.

The beneficial effect that the utility model brings has:

Through structural improvement, the utility model provides a double air intake and ejection mold opening structure with side ejection and side double blowing. As a new demoulding method, when the mold is opened and ejected, the double air can Entering the inner side of the product, the product will automatically fall off, thereby ensuring that the product will not break or deform, and avoid the occurrence of strong breakage and deformation of the product. In addition, its structural design is simple and reasonable, and the difficulty and cost of mold release are greatly reduced. It is a plastic spring. An important breakthrough in the technical difficulties of vacuum pump production operations.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described,

Accompanying drawing 1 is a schematic diagram of the structure of the utility model.

Detailed ways

Referring to accompanying drawing 1, the utility model provides us with a vacuum pump double air intake and ejection mold opening structure, and its demoulding method of ejecting on one side and double blowing on the other side can effectively avoid the phenomenon of strong product breakage, deformation and the like.

Specifically, as a new demoulding method, its structure mainly includes an upper mold 1 and a lower mold 2, and a mold parting surface 3 is formed between the upper mold 1 and the lower mold 2, wherein the upper end of the lower mold 2 is provided with a product forming Part 4, the product pushing part is connected under the product forming part 4, and the product pushing part includes a thimble, a thimble bottom plate 51 and a top roller 52, and an air inlet valve 6 is connected to the side thereof.

In the above structure, the product forming part 4 has a symmetrical structure, which is mainly reflected in its left-right symmetrical structure. At the same time, there are two sets of forming molds 41 in front and back, and each set of forming molds 41 corresponds to a product pushing part.

At the same time, both ends of the product forming part 4 are provided with inclined guide grooves, and when the upper mold 1 and the lower mold 2 are in the mold clamping state, inclined guide posts 7 are installed therein. The outer side of the product forming part 4 is provided with a positioning block 8, which is fixed on both ends of the product forming part 4 through the inclined guide pillar 7. When the upper mold 1 and the lower mold 2 are in the mold opening state, the inclined guide pillar 7 and the row position Block 8 just opens successively and is convenient to mold opening.

In addition, the above-mentioned top roller 52 is arranged at the bottom of the lower mold 2, and above it is the bottom plate 51 of the ejector pin. The valve 6 is connected, and the thimble bottom plate 51 drives the thimble upwards under the push of the top roller 52 to open the intake valve 6 . Therefore, a double-inlet ejection mold opening structure with side ejection and side double blowing is formed.

As a new demoulding method, when the mold is opened and ejected, the utility model can enter the inner side of the product, so that the product will fall off automatically, thereby ensuring that the product will not break or deform, and avoid strong product breakage, deformation, etc. In addition, its structural design is simple and reasonable, and the difficulty and cost of mold release are greatly reduced.
