Abstract

The utility model provides a guide-rail-type mold base, which comprises an upper mold body and a lower mold body, which are arranged inside a framework, wherein two sides of the framework are respectively provided with a crossbeam, and a guide rod is vertically and fixedly arranged between an upper frame body and the crossbeams of the framework; and the side wall of the upper mold body is fixedly connected with a guide sleeve, and the guide sleeve is movably clamped on the periphery of the guide rod. The movement friction of the upper mold body is reduced, so that accuracy in movement is achieved, no deviation exists, convenience in production is achieved, and the quality and production efficiency of a machined product can be improved.

Description

A kind of guide tracked mould bases

Technical field

The utility model relates to mechanical equipment technical field, is specifically related to the guide tracked mould bases that a kind of high-pressure foam is used.

Background technology

The use of automobile, passenger vehicle is more and more universal, and in order to create more comfortable, safe environment inside car, the inside gadget of automobile, passenger vehicle such as instrument desk etc. all use high-pressure foam technique to make.Because the semi-rigid expanded material that this foam process is produced can absorb kinetic energy and the noise in various sources, so that instrument desk has the performance of resistance to compression, antidetonation, and improved its surperficial comfort level, guaranteed that the passenger has safer, comfortable driving space.At present, high-pressure foam technique all is to adopt high-pressure foam equipment and robotic device form, be foamed material after high-pressure foam equipment mixes, by carrying out injection mo(u)lding in the mechanical pistol head perfusion progressive die tool, this requires freely free-running operation track in lower mould of manipulator Filling gun head.

The folding of mould is put mould to the automatic open-close of realizing mould with mould bases through initial manually lifting, and has reached the requirement of automation.But present mould bases mostly is greatly the rack-and-pinion mould bases, drive the lifting of upper die body by gear moving up and down on tooth bar, though made things convenient for operation, but because there is dislocation in gear when tooth bar moves, cause the up and down operation of upper die body to have asynchronism with it, then can so that have displacement difference between upper die body and the lower mold body, actual production be brought inconvenience, and cause the defectives such as product quality is defective, production efficiency is low during matched moulds.

The utility model content

The utility model will solve above-mentioned deficiency exactly, and a kind of guide tracked mould bases is provided, and improves the accuracy that mould bases is produced, thereby improves product quality and production efficiency.

In order to reach above-mentioned effect, the utility model provides a kind of guide tracked mould bases, comprises upper die body and the lower mold body of being located at framework inside, and a crossbeam is respectively established in the both sides of described framework, the vertical guide rod that sets firmly between the upper frame body of framework and the crossbeam; Sidewall and the guide pin bushing of described upper die body are affixed, and described guide pin bushing active card is located at the guide rod periphery.

Described guide rod has four, is symmetrically set in the both sides of framework.

Described upper die body top is provided with and drives its cylinder that moves both vertically, and described lower mold body is connected with the cylinder that drives its front and back horizontal movement, and the bottom of lower mold body is installed with guide wheel.

In order to make moving up and down of upper die body more steady, synchronous, described guide pin bushing inside is provided with ball, and guide pin bushing moves both vertically up and down along guide rod.

The utility model is established guide rod in the both sides of framework, to be located at guide rod with the affixed guide pin bushing active card of upper die body hits outward, rely on the tangent rolling-operation that carries out of the inner rolling steel ball of guide pin bushing and guide pillar surface, reduce the frictional force that moves up and down of upper die body, and the deviation that does not have lateral displacement has more guaranteed the accuracy of the lower motion of upper die body.Adopt the axially-movable between guide pin bushing and the guide rod, guarantee relative with moving both vertically of the affixed upper die body of guide pin bushing steadily and synchronously.Guarantee in motion process, upper die body is accurate horizontal and vertical direction, has increased the stability of mould bases operation.

The upper die body top is provided with and drives its cylinder that moves both vertically, and order about upper die body and move up and down, thus the motion of drive guide pin bushing, and guide pin bushing can only be done axially along guide rod, so the accuracy that moves up and down of upper die body is high.When in lower mold body, carrying out material feeding or feeding, can be by its front and back horizontal movement of air cylinder driven that is connected with lower mold body, the guide wheel of lower mold body bottom just seesaws along the guide rail of being located at the framework bottom surface, is convenient for people to operation.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the utility model structural front view;

Fig. 2 is the utility model structure side view;

Among the figure, 1-framework, 2-upper die body, 3-lower mold body, 4-cylinder, 5-guide wheel, 6-guide pin bushing, 7-guide rod, 8-crossbeam, 9-guide rail.

The specific embodiment

As shown in Figure 1 and Figure 2, a kind of guide tracked mould bases comprises the upper die body 2 and lower mold body 3 of being located at framework 1 inside, a crossbeam 8 is respectively established in the both sides of described framework 1, the vertical guide rod 7 that sets firmly between the upper frame body of framework 1 and the crossbeam 8, guide rod 7 has four, is symmetrically set in the both sides of framework 1; The sidewall of described upper die body 2 and guide pin bushing 6 are affixed, and guide pin bushing 6 active card are located at guide rod 7 peripheries, and guide pin bushing 6 inside are provided with ball, and guide pin bushing 6 moves both vertically up and down along guide rod 7.Upper die body 2 tops are provided with and drive its cylinder that moves both vertically 4, and described lower mold body 3 is connected with the cylinder that drives its front and back horizontal movement, and the bottom of lower mold body 3 is installed with guide wheel 5 and seesaws along the guide rail 9 of being located at framework 1 bottom surface.

During work, first the effect of lower mold body by cylinder skidded off along guide rail, add raw material, again it is pushed in the framework, then start the cylinder on upper die body top, driving it down does and moves both vertically, upper die body drives the guide pin bushing that is fixed together with it and down moves, and guide pin bushing can only axially move along guide rod, thereby makes the kinetic friction force of upper die body reduce, accurately not drop on the lower mold body with being offset, overlap completely with lower mold body, so add satisfactory product.Make things convenient for production, and improved into product quality and production efficiency.After machining, upper die body up moves under the drive of its top cylinder and leaves lower mold body, and lower mold body is left framework under the effect of cylinder, take out the product that processes.

Above embodiment is not limited only to protection domain of the present utility model, all make amendment based on basic thought of the present utility model or change all belong to protection domain of the present utility model.
