Abstract
A reinforced *-shaped injection molding machine fixed template comprises a *-shaped fixed template; a sloping side reinforcing rib of the * shape turns into two reinforcing ribs, and a reinforcing rib which is distributed peripherally between two pull bar contact surfaces is added. Each pull bar contact surface is connected with four reinforcing ribs, which greatly improve the rigidity of the pull bar contact surface, and transmit mold clamping force to each pull bar contact surface; the deformation of the pull bar contact surface is obviously reduced; the pull bar is only subjected to stretching stress; fatigue break caused by bending stress is reduced; and the service life of the pull bar is greatly prolonged. Meanwhile, since original hollow design is maintained, the weight of the whole template is less than that of an original template; therefore, the template of the utility model is quite suitable for injection molding machines requiring both high-product precision and low-cost large-scale manufacturing, and truly realizes optimization of cost performance.
Description
Technical field
The utility model relates to the fixed form of injection machine.
Background technology
In plastic-injection moulding machine matched moulds process, whole clamping generation strain, wherein fixed form is subjected to producing flexural deformation behind the mold clamping force pressurized, the main tension of pull bar and extending.Because fixed form plays fixed mould and transmits the effect of clamp force, thereby so the rigidity of the fixed form stress that directly influences mould influence performance and the outward appearance of final plastic products.Being to cause one of pull bar major cause of failure owing to pull bar is subjected to the fatigue stress that the distortion of fixed form causes in addition, is main task of the present utility model so improve the rigidity of fixed form.
Common now fixed form has: solid overall structure (especially in medium and small type), and structures such as box, the I-shaped of optimizing gradually afterwards, rice type muscle.Generally be target with the equal strength in the optimal design process of these templates, thus bigger than normal in the distortion of mould and pull bar contact position, cause thus that the mould bearing load is inhomogeneous, distortion is inhomogeneous, finally influenced quality of item and mould and pull bar life-span.
Although Yan Fa Elastic forming board was very big in the even supporting effect improvement of mould in recent years, template itself consumes material but to be increased on the high side; In addition, the increase of template thickness also brings the material of auxiliary device to increase synchronously, increases cost, so this class Elastic forming board is not suitable in enormous quantities, use in the environment cheaply.
The utility model content
Technical problem to be solved in the utility model is that a kind of reinforcement rice font injection machine fixed form is provided for the above-mentioned deficiency that overcomes prior art, and its materials province, stress and distortion are evenly distributed.
The utility model solves the problems of the technologies described above the technical scheme that adopts: strengthen rice font injection machine fixed form, comprise the M shape fixed form, it is characterized in that: the hypotenuse reinforcement of described rice font becomes two reinforcements, increases simultaneously between two pull bar contact-making surfaces along the reinforcement that distributes all around.
Compared with prior art, advantage of the present utility model is: because each pull bar contact-making surface has four reinforcements to connect, increased the rigidity of pull bar contact-making surface greatly, and mold clamping force can be delivered to each pull bar contact-making surface by four reinforcements, the distortion of pull bar contact-making surface obviously reduces, thereby make pull bar only be subjected to tensile stress, reduced bending stress and the fatigue fracture that causes, the first mate has prolonged the service life of pull bar.Simultaneously, because keep original naughty empty design, integral mold plate weight is lighter than original template on the contrary, so be very suitable for both requiring high accuracy goods demand, need simultaneously the injection machine equipment made low-costly and in high volume again, really realized the optimization of cost performance.

Fig. 2 is the E-E cutaway view of Fig. 1.
Fig. 3 is the rearview of the utility model embodiment.
The specific embodiment
Describe in further detail below in conjunction with the utility model of accompanying drawing embodiment.
The M shape structure of injection machine fixed form is the structure of relatively using always, gains the name because its structure is a meter word.
As shown in Figure 1, 2, 3, the tradition rice typing basic structure of injection machine fixed form is constant among the embodiment of the present utility model, and the hypotenuse reinforcement of traditional M shape is become two reinforcements 3 and reinforcement 4.
Between two pull bar contact-making surfaces 5 of four jiaos reinforcement 1 and reinforcement 2 are set, preferably reinforcement 1 and reinforcement 2 outers are raised to pull bar contact-making surface 5 to extension as far as possible.
Owing to have reinforcement 1 and reinforcement 2, reinforcement 3 to support with reinforcement 4 around the pull bar contact-making surface 5, therefore strengthened the rigidity of pull bar contact-making surface 5 greatly.
Injection machine fixed form remainder adopts washes in a pan empty design, transmits clamp force with the fixed form reinforcement, with existing M shape structural similarity, is not described in detail at this.
Claims (1)
1. strengthen rice font injection machine fixed form, comprise the M shape fixed form, it is characterized in that: the hypotenuse reinforcement of described rice font becomes two reinforcements, increases simultaneously between two pull bar contact-making surfaces along the reinforcement that distributes all around.
