Abstract

The utility model discloses a forming mechanism of a plastics forming machine, which is characterized in that the forming mechanism comprises a forming mould, a motor, a cam, an oscillating bar device, a toggle and a guide column, a lower die holder of the forming mould is arranged on the guide column in a sliding manner, the guide column is fixedly connected with a machine base of a mechanism body, the cam is connected to a cam shaft, the cam shaft is arranged on the machine base in a rotatable manner and in transmission connection with the motor, the oscillating bar device is hinged with the machine base of the mechanism body, the oscillating bar device is provided with a roller contacting the work surface of the cam, and the two ends of the toggle are respectively hinged with the oscillating bar device and the lower die holder. The forming mechanism has the advantages that the die opening and closing speed is high, the mould closing pressure is large and stable, the production efficiency and quality are improved, and the product grade is promoted.

Description

The plastic molding press shaping mechanism
[technical field]
The utility model relates to a kind of plastic molding press, is specifically related to a kind of shaping mechanism of plastic molding press.
[background technology]
Plastic molding press is an equipment of producing various plastic products, uses very extensive.The mould folding of the plastic molding press shaping mechanism of prior art moves up and down by cylinder promotion mould die shoe and finishes, but the influence that is subjected to cylinder and source of the gas causes, and speed is unhappy, thrust not quite and is inadequately stablized, and has restricted efficiency of equipment and product quality.
[summary of the invention]
In view of the problem that present known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of opening and closing mould speed fast, and clamping pressure is the plastic molding press shaping mechanism greatly and stably.
For solving the problems of the technologies described above, the utility model takes following technical scheme to finish:
The plastic molding press shaping mechanism, it is characterized in that: described shaping mechanism comprises mould, motor, cam, fork device, toggle and guide pillar, the die shoe of mould slides and is located on the guide pillar, guide pillar is fixedlyed connected with the body support, cam is connected on the camshaft, rotatable being located on the body support of camshaft is in transmission connection with motor, fork device and body support are articulated and connected, the fork device is provided with the roller that contacts with cam working face, and the two ends of described toggle are articulated and connected with fork device and die shoe respectively.
The utility model with motor as power transmission, promote the swing of fork device by cam, promote die shoe by toggle at last, the folding mould speed of mould is greatly enhanced, mold clamping force is big and steady simultaneously, improve production efficiency and product quality, promoted product specification.
As preferably, described fork device has parallel four-bar linkage structure, comprises a cross bar and two isometric forks that be arranged in parallel, and fork lower end and body support are articulated and connected, and the fork upper end connects by cross bar.
[description of drawings]
The utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model
[specific embodiment]
Accompanying drawing has been represented the technical solution of the utility model, further describes each relevant details and operation principle thereof of the example below more in conjunction with the accompanying drawings.
With reference to accompanying drawing 1, this kind plastic molding press shaping mechanism, comprise mould, motor 1, cam 10, the fork device, toggle 4 and guide pillar 6, the die shoe 5 of mould slides and is located on the guide pillar 6, guide pillar 6 is fixedlyed connected with body support 9, cam 10 is connected on the camshaft 11, camshaft 11 rotatable being located on the body support 9 are in transmission connection with motor 1, the fork device has parallel four-bar linkage structure, comprise a cross bar 3 and two isometric forks that be arranged in parallel 2 and 7, article two, fork lower end and body support 9 are articulated and connected, and two fork upper ends connect by cross bar 3, and fork 7 is provided with roller 8, roller 8 abuts on the working face of cam 10, the two ends of described toggle 4 are articulated and connected with fork device and die shoe 5 respectively, and toggle and fork device are articulated in the A point, and toggle and die shoe are articulated in the B point.
The utility model is work like this: motor rotates, be sent to power on the camshaft and then the rotation of drive cam by deceleration device, cam working face forces the swing of roller belts movable pendulum lever apparatus, the swing of fork device promotes die shoe by toggle and moves up and down on guide pillar, thereby the opening and closing mould action of realization mould, folding mould speed is fast, mold clamping force is big and steady simultaneously.
The utility model with motor as power transmission, promote the swing of fork device by cam, promote die shoe by toggle at last, the folding mould speed of mould is greatly enhanced, mold clamping force is big and steady simultaneously, improved production efficiency and product quality, promoted product specification, will bring very big facility and positive result of use to the user.
