Abstract
The utility model belongs to the technical field of molds, and particularly relates to a liquid crystal display press key injection mold. The liquid crystal display press key injection mold comprises a stationary mold core, a movable mold core, and an ejector mechanism used for ejecting manufactured products, wherein the ejector mechanism comprises an ejector plate, an ejector plate fixing plate and an ejector pin fixed on the ejector plate fixing plate, the stationary mold core and the movable mold core form a product mold cavity after being combined, the tail end of the product mold cavity is provided with an excess material cavity, one end of the excess material cavity is connected with the product mold cavity and is a connection end, and the connection end is preferentially cone-shaped. The upper portion of the ejector pin is situated right below the excess material cavity, ejects the manufactured products coordinating with the excess material cavity, and therefore direct contact between the ejector pin and the surface of transparent press key manufactured products is avoided, and good appearance quality of transparent manufactured products is guaranteed.
Description
The utility model belongs to technical field of mold, is specifically related to a kind of LCD button injection mold.
Background technology
Injection moulding as one of forming method important in the plastic processing, has obtained extensive use in industrial circle.Along with the use of plastic products is increasingly extensive, people have higher requirement to surface quality, intensity and the precision of plastic products.This just requires the injection mold of plastic products must possess good formed product performance, and especially for PMMA (polymethyl acrylate the is commonly called as lucite) material of making the LCD transparent push, surface quality requires higher.
At present, in the existing LCD button injection mold production technology, adopt sub marine gate or some cast gate running gate system more.Narrow and small because of the cast gate width, section is irregular, often has the cast gate defective material to stay goods plastic surface, and is prone to produce bubble and current mark; When using thimble to eject goods, be prone to produce the thimble vestige at product surface, influenced the presentation quality of goods, be difficult to satisfy the surface quality requirement of transparent article.
The utility model content
The utility model provides a kind of LCD button injection mold, can effectively avoid the cast gate defective material to stay the deficiency on transparent article plastic surface.
In order to solve the realization above-mentioned purpose, the utility model is taked following technical scheme:
A kind of LCD button injection mold; Comprise cover half core rod, dynamic model core rod and the ejecting mechanism that goods are ejected; This ejecting mechanism comprises push pedal, push pedal fixed head and is arranged on the thimble on the push pedal fixed head; Form the goods die cavity behind cover half core rod and the dynamic model core rod matched moulds, said goods die cavity end is provided with the clout chamber, and thimble top is positioned under the clout chamber.
As the further improvement of the utility model, the end that said clout chamber is connected with the goods die cavity is a link; Wherein, the tapered shape of link, link near the wall thickness of the terminal side of goods die cavity greater than link away from the terminal side of goods die cavity.
As the further improvement of the utility model, the cone angle of said link is 15 degree.
As the further improvement of the utility model, said dynamic model core rod inside is provided with the cooling water channel that goods die cavity inner product is formed cooling.
The beneficial effect of the utility model is:
Goods die cavity end in LCD button injection mold is provided with the clout chamber; And cooperate with thimble under being positioned at the clout chamber, avoided thimble to contact with the direct of transparent push product surface, treat that goods take out after; Can conveniently the clout section be excised; Effectively prevent the appearance of product surface thimble vestige, in actual production, kept the presentation quality of button goods to a great extent; As the advantageous embodiment of the utility model, the link of clout chamber and goods die cavity is chosen cone-shaped, makes that the operability of clout section excision increases greatly after the goods taking-up.
Description of drawings
Fig. 1 is the sketch map of a kind of LCD button injection mold in the utility model;
Fig. 2 is the A portion enlarged drawing among Fig. 1, and the sketch map that the clout chamber cooperates with the goods die cavity has been shown among the figure;
Fig. 3 is the cutaway view along B-B line among Fig. 2;
Wherein, 1-cover half core rod, 2-dynamic model core rod, 30-push pedal, 31-push pedal fixed head, 32-thimble, 4-goods die cavity, 5-clout chamber, 50-link, 6-cooling water channel.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further specified:
Extremely shown in Figure 3 in conjunction with Fig. 1; A kind of LCD button injection mold; Comprise cover half core rod 1, dynamic model core rod 2 and the ejecting mechanism that goods are ejected, ejecting mechanism comprises push pedal 30, push pedal fixed head 31 and is arranged on the thimble 32 on the push pedal fixed head 31 that cover half core rod 1 forms goods die cavity 4 afterwards with dynamic model core rod 2 matched moulds; The end of goods die cavity 4 is provided with clout chamber 5; Above-mentioned thimble 32 tops be positioned at this clout chamber 5 under, thimble 32 cooperates with clout chamber 5 transparent push goods in the goods die cavity is ejected, and can not cause damage or stay the thimble trace product surface; Treat can the excision of the clout section in the clout chamber have been guaranteed the good appearance quality of goods after goods take out.
The end that clout chamber 5 is connected with goods die cavity 4 is a link 50; These link 50 tapered shapes; Increased the operability of taking out clout section excision behind the goods greatly, wherein, link 50 near the wall thickness of goods die cavity 4 terminal sides greater than link away from the terminal side of goods die cavity.As preferably, the cone angle of link 50 is 15 degree.
Dynamic model core rod 2 inside are provided with the cooling water channel 6 that goods die cavity 4 inner product is formed cooling, are used for the cooling to the button transparent article at injection moulding process.
Certainly, above-mentioned explanation is not to be the restriction to the utility model, the utility model also be not limited in above-mentioned for example, the variation that the technical staff in present technique field is made in the essential scope of the utility model also should belong to the protection domain of the utility model.
