Background

The existing extrusion molding device for plastic pipe connectors adopts a press machine which moves up and down as a mode locking device, and the device is mainly used for manufacturing the connectors of plastic pipes. When the production line of the pipe produces the pipe and carries out the production line after the fixed-length cutting, the pipe at the moment can not be directly connected with the pipe, and the extrusion molding device of the plastic pipe connector on the pipe is required to be processed for facilitating the installation and construction of the pipe. The device comprises an outer die (an upper die and a lower die) and a core die for extruding a connector, wherein when a pipe reaches a designated position, the core die props against the inside of the pipe, the outer die moves up and down simultaneously to clamp the outside of the pipe, after the outer die and the core die are tightly closed, a nearly closed space is formed inside the pipe, at the moment, a plastic extruder injects molten plastic into the closed space, and the pipe connector is formed after cooling and forming.

Because the upper and lower die assemblies are driven by the hydraulic oil cylinder, the injection pressure reaches 15-20MPa, the upper and lower oil cylinders are difficult to achieve the high die locking force, and material leakage is easily caused; moreover, the upper and lower movable parts cannot establish high-pressure mold locking, and the core mold is easily crushed. If the high clamping force mold is replaced, the mold cost will rise; if the mold locking oil cylinder is enlarged for improving the mold locking force, the cost of the device is increased, and the action is slowed down after the oil cylinder is enlarged, so that the production efficiency is influenced.

SUMMERY OF THE UTILITY MODEL

To the above problem, the utility model provides a crowded formula of annotating forming device of plastics tubular product connector solves the unable reliable locking mould of current device, and the mould can be because of injection pressure height by the back-up, leads to the unable fashioned problem of connector.

A plastic pipe connector extrusion molding device comprises a core mold, an upper mold and a lower mold, wherein the upper mold is driven by an upper locking oil cylinder, the lower mold is driven by a lower locking oil cylinder, and the plastic pipe connector extrusion molding device further comprises at least two half clamping mechanisms which are oppositely arranged; the upper die and the lower die are arranged on the contact surface of the upper die and the lower die, at least two groups of convex blocks are oppositely arranged outwards from top to bottom, and the half clamping mechanism is used for clamping the opposite group of convex blocks.

Furthermore, the half clamping mechanism comprises a half locking oil cylinder and a half clamp driven by the half locking oil cylinder.

Furthermore, the half clamp is fixed on an output shaft of the half locking oil cylinder.

Furthermore, a first monitoring point is arranged on the half clamp, a second monitoring point is arranged below the protruding block, and when the two monitoring points are overlapped, locking is in place.

Furthermore, the half clamping mechanism is installed on the lower die through a tripod, and the tripod is fixedly connected with the lower die through screws.

The utility model has the advantages that: the arrangement of the half clamping mechanism greatly reduces the pressure of the hydraulic systems of the upper die and the lower die, so that the power of the hydraulic pump of the upper die and the lower die can be reduced, and the energy consumption is saved; the action speed of the hydraulic pump power equipment of the upper die and the lower die is reduced, so that the working efficiency is improved; meanwhile, the upper die and the lower die are more stable in die assembly, can bear larger injection pressure and are not easy to be jacked open, the product percent of pass is improved, the compactness of the connector is improved, and the connector is firmer; the automation degree of the device is improved, the labor is saved, and the requirement on operators can be reduced.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.

Example 1

A plastic pipe connector extrusion molding device is shown in figure 1 and comprises a core mold 1, an upper mold 2 and a lower mold 3, wherein the upper mold 2 is driven by an upper locking oil cylinder 4, the lower mold 3 is driven by a lower locking oil cylinder 5, and the device further comprises at least two half clamping mechanisms which are oppositely arranged; the upper die 2 and the lower die 3 are provided with at least two groups of convex blocks 6 which are oppositely arranged outwards from top to bottom on the contact surfaces of the upper die and the lower die, and the half clamping mechanism is used for clamping the opposite group of convex blocks.

After the upper die and the lower die are assembled, the half clamping mechanism clamps the opposite group of the protruding blocks, so that the upper die and the lower die are kept in a closed state, and the half clamping mechanism can be matched with a switch circuit for protection, thereby ensuring the mechanical safety.

The arrangement of the half clamping mechanism greatly reduces the pressure of the hydraulic systems of the upper die and the lower die, so that the power of the hydraulic pump of the upper die and the lower die can be reduced, and the energy consumption is saved; the action speed of the hydraulic pump power equipment of the upper die and the lower die is reduced, so that the working efficiency is improved; meanwhile, the upper die and the lower die are more stable in die assembly, can bear larger injection pressure and are not easy to be jacked open, the product percent of pass is improved, the compactness of the connector is improved, and the connector is firmer; the automation degree of the device is improved, the labor is saved, and the requirement on operators can be reduced.

Specifically, in the present example, as shown in fig. 2, the half clamping mechanism includes a half locking cylinder 7 and a half clamp 8 driven by the half locking cylinder; the half clamp is fixed on an output shaft 9 of the half locking oil cylinder. Through controlling the first oil port 14 and the second oil port 15 on the half locking oil cylinder to discharge or feed oil, the piston in the half locking oil cylinder can move relatively in the oil cylinder, so that the relative position of the half clamp and the convex block is adjusted.

The half clamp is provided with a first monitoring point 10, a second monitoring point 11 is arranged below the protruding block, when the two monitoring points are overlapped, locking is indicated to be in place, accurate positioning of a die assembly position is achieved, and the die is better protected from mechanical damage. As for how to realize that the locking is in place when the two monitoring points are superposed, the locking can be realized by the prior art, such as infrared detection, namely, an infrared transmitting end is arranged on the first monitoring point, an infrared receiving end is arranged on the second monitoring point, and when the infrared receiving end receives an infrared signal transmitted by the infrared transmitting end, the locking in place is judged, so that the Haff locking oil cylinder stops acting.

The half clamping mechanism is installed on the lower die through a tripod 12, and the tripod is fixedly connected with the lower die through a screw 13.

It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them.
