Description

Forming die of lawn mower fender mud side cap
Technical Field
The utility model belongs to the technical field of the mould and specifically relates to a forming die of lawn mower fender mud side cap is related to.
Background
Injection molding refers to a process used in mass production of parts having complex shapes. Specifically, the material melted by heating is injected into a die cavity, and a molded product is obtained after cooling and solidification. The injection mold is a tool for producing plastic products and also a tool for endowing the plastic products with complete structures and accurate sizes, and generally comprises a movable mold and a fixed mold, wherein the movable mold is arranged on a movable mold plate of an injection molding machine, and the fixed mold is arranged on a fixed mold plate of the injection molding machine. And when the mold is opened, the movable mold is separated from the fixed mold so as to take out the plastic product.
Fig. 1 shows a lawn mower fender cover, which comprises two cover plates that are bilaterally symmetrical, and is formed by changing an original metal part of the lawn mower fender cover into a plastic part and injection molding the plastic part with a mold, so that the weight of the lawn mower fender cover is reduced, and the qualification rate of products is ensured.
Disclosure of Invention
The utility model aims to solve the technical problem that a forming die of lawn mower fender mud side cap is provided, two sliding block set spares through bilateral symmetry and lower core combination form the die cavity shaping to utilize the back-off device to prevent sliding block set spare swift current, guarantee the goods qualification rate.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: a forming die of a mud blocking side cover of a mower comprises an upper die and a lower die, wherein the lower die is provided with a lower die core, the lower die core is provided with two slide block components which are bilaterally symmetrical, the slide block components and the lower die core are combined to form a die cavity, the slide block components are provided with an inverted buckle for preventing the slide block components from returning, the inverted buckle is fixedly connected with the upper die and is provided with a first surface and a second surface, the slide block components comprise a slide block and an oil cylinder for pushing the slide block, the slide block comprises a forming part and a pushing part, the forming part is provided with a third surface and a forming surface adjacent to the lower die core, the pushing part is provided with a plurality of slide rails and a first groove matched with the inverted buckle, the first groove comprises a fourth surface and a fifth surface, the first surface is in sliding connection with the fourth surface, and the second surface is adjacent to the fifth surface, the lower die is provided with a second groove, and the reverse buckle penetrates through the first groove and is connected with the second groove in an inserting mode.
As a further improvement of the utility model, the first face, the second face and the third face are all provided with wear-resisting blocks. The upper die and the sliding block are frequently rubbed in the moving process, and the sliding block and the inverted buckle are abraded in the long term, so that the whole sliding block or the inverted buckle must be replaced.
As a further improvement, the oil cylinder and the lower die are fixedly connected through a connecting piece, and the oil cylinder and the sliding block are connected through a T-shaped block. Because the volume of the lower die per se is not enough to support the movement stroke of the sliding block, the stroke is increased continuously through the connecting piece, and the T-shaped block facilitates the connection of the oil cylinder and the sliding block.
As a further improvement of the utility model, the lower mould be provided with the thimble and be used for promoting the roof that the thimble removed. When the mould is carrying out the drawing of patterns operation, need drive thimble upward movement through the roof to ejecting fender mud side cap, the workman of being convenient for takes out.
The utility model discloses a theory of operation: two hydro-cylinders of bilateral symmetry promote the slider and form the die cavity with lower core combination, and the shaping goods because there is certain pressure at the in-process of moulding plastics, and the thrust of hydro-cylinder is not enough, then can lead to the slider to produce and roll back, so recycle the back-off and insert first recess until with second groove position, guarantee that the slider can not produce the back-slip to guarantee the goods qualification rate.
Compared with the prior art, the utility model has the advantages of simple structure, reasonable in design, two sliding block set spare through bilateral symmetry combine to form the die cavity with lower core module, shaping goods to utilize the back-off to prevent the slider swift current, in order to guarantee the goods qualification rate. The hydro-cylinder drives the slider and removes, the propulsion portion of slider is provided with a plurality of slide rails, play the guide effect, it is smooth and easy to make the slider activity, the shaping portion of lower mould core and slider merges, can the shaping goods, back-off and last mould fixed connection, along with the downstream of last mould, the back-off also follows the downstream of doing, the first face of back-off and the fourth face sliding connection of first recess, and after the tip of back-off passed first recess, peg graft with the second recess of lower mould, guarantee that the slider can not produce and roll back, in order to ensure the goods qualification rate.
